Exemplary embodiments of the present invention are described in detail below with reference to the accompanying drawings. The same reference numerals in the drawings denote the same parts. As shown in FIG. 1 to 4, a hydraulic synchronizer according to the present invention includes: a closed first case 1 including a first support base 18 and a first disposed opposite to the first support base 18. The second support base 19, the first support base 18 and the second support base 19 may be respectively sealingly mounted to the box body 1, or at least one of them may be integrally formed with the first box body 1; Input shaft 2 and output shaft 14 on first support base 18 and second support base 19, in an exemplary embodiment, input shaft 2 and output shaft 14 are mounted on the same axis; and are disposed on the input shaft 2 and a coupling means between the output shaft 14, which couples the rotation of the input shaft 2 to the output shaft 14, and finally causes the output shaft 14 to rotate in synchronism with the input shaft 2, thereby causing the output shaft 14 to drive the load.

In an exemplary embodiment of the invention, the coupling device comprises: a second housing 5 comprising a first end cap fixedly connected to the input shaft 2 extending into the interior of the first support base 18 3. And a second end cover 9 mounted between the output shaft 14 and the second support base 19 by a bearing structure, the second end cover 9 being rotatable relative to the second support base 19 and the output shaft 14, respectively; the support frame 21 The support frame 21 is rotatably mounted on the output shaft 14 between the first end cover 3 and the second end cover 9: a plurality of bucket wheels 22, the plurality of bucket wheels 22 are equally spaced through the bucket The axle 4 is rotatably mounted between the first end cap 3 and the support frame 21, wherein each bucket wheel 22 is fixedly mounted on a respective bucket wheel axle 4 and located at the periphery of the input shaft 2, each bucket axle 4 being disposed at On the circle centered on the axis of the input shaft 2; a plurality of pinion gears 7, each fixedly mounted on the bucket wheel shaft 4 extending from the support frame 21, in one embodiment, the pinion gear and the bucket An axle is integrally formed; an output device, the output device position Between the support frame 21 and a second end cap 9, and includes a large gear fixedly mounted on the output shaft 14 6. The bull gear 6 includes a flange 8 and a ring gear portion having an engaging tooth on the inner side extending perpendicularly from the end of the flange 8. The ring gear portion of the large gear 6 is located outside the plurality of pinion gears 7 and meshes with each of the pinion gears 6 by gear meshing. In the present invention, the number of the bucket wheel 22 and the pinion 7 may be 2 - 10, preferably 4 - 8, and most preferably 6.

According to the present invention, each bucket wheel 15 includes two mutually spaced support plates 24 fixedly mounted on the bucket wheel shaft 4, and a plurality of bucket wheel blades 25 mounted between the support plates 24 around the bucket wheel axle 4. As shown in Fig. 2, the cross section of the bucket wheel blade 25 in the direction perpendicular to the axial direction of the input shaft has an arcuate shape, so that the bucket wheel blade 25 and the two support plates 24 constitute an open container structure capable of accommodating a certain liquid. The specific number of bucket wheel blades can be set as desired, and each bucket wheel blade 25 has a predetermined spacing therebetween. Thus, when the second casing 5 is rotated, the liquid contained in the second casing 5 is allowed to enter the container structure.

In an exemplary embodiment of the invention, at least one (such as one or two) fusible plugs 20 may be provided on the side wall of the casing 5 between the first end cap 3 and the second end cap 9. . When the pressure or temperature in the second tank 5 Above the predetermined value, the fusible plug 20 is automatically smashed, thereby discharging the liquid (e.g., oil) 28 in the second tank 5, thereby preventing damage to the second tank 5.

When the hydrodynamic synchronizer according to the present invention is operated, a driving device such as an electric motor drives the second casing 5 to rotate through the input shaft 2 while the working fluid 28 such as oil stored in the first casing 1 is to be stored. It is delivered into the second tank 5 by means of a working pump. When the second casing 5 has just started to rotate, the flange 8 and the large gear 6 fixedly coupled to the output shaft 14 are not rotated due to the load on the output shaft 14. At this time, the pinion gear 7 meshing with the large gear 6 revolves around the bucket wheel shaft 4 in the direction opposite to the rotation direction of the input shaft 2 while revolving around the input shaft 2 as the second casing 5 revolves, and drives the bucket The wheel 22 rotates around the bucket wheel shaft 4 in a direction opposite to the direction of rotation of the input shaft 2. As the second casing 5 continues to rotate, the liquid contained in the second casing 5 forms an annular liquid surface on the cylindrical inner surface of the second casing 5 due to the centrifugal force. When the liquid level reaches a predetermined height, the liquid enters the concave bucket wheel blades 25 of the respective bucket wheels 22. Due to the centrifugal force, the liquid entering the bucket wheel 25 forces the rotation speed of the bucket wheel 22 to decrease due to the centrifugal force, so that the rotational speed of the bucket wheel 22 and the pinion 7 is not synchronized with the rotational speed of the input shaft 2. Thus, the pinion gear 7 gradually drives the large gear 6 meshing therewith to rotate, thereby rotating the output shaft 14, thereby driving the load coupled to the output shaft 14 from the stationary state to the moving state, realizing a soft start of the load.

As the second casing 5 continues to rotate, the liquid 28 entering the concave bucket wheel blades 25 of the respective bucket wheels 22 continues to increase, and the centrifugal force increases, which forces the bucket wheel 22 and the pinion gear 7 to no longer wrap around the bucket. The axle 4 rotates. At this time, the pinion 7 drives the large gear 6 meshed therewith to rotate synchronously with the input shaft 2, thereby causing the input shaft 2 and the output shaft 4 to rotate synchronously, thereby achieving complete driving of the input shaft 2 to the output shaft 14. It can be understood that in the case of full drive, the centrifugal torque of the liquid is balanced by the action of the gear mechanism and the drag torque of the load.

According to the invention, an adjustment device for adjusting the liquid level of the liquid 28 in the second tank 5 is provided. As can be seen from the above description, when rotating, the liquid level of the liquid attached to the inner surface of the second casing 5 determines the magnitude of the centrifugal force, and the magnitude of the centrifugal force determines whether the output shaft 14 can be the same as the input shaft 2.歩 Rotate. Further, the greater the centrifugal force, the more the output shaft 14 tends to rotate in synchronization with the input shaft 2, and the smaller the slip between the output shaft 14 and the input shaft. Conversely, the greater the slip.

In an exemplary embodiment of the present invention, the third end cover 10 is further disposed on the outer side of the second end cover 9, and one end of the third end cover 10 is connected to the second end cover 9 by a bolt structure. Alternatively, it is formed integrally with the third end cap 10 to form an attachment cavity 23 between the second end cap 9 and the third end cap 10. The chamber 23 is in communication with the second tank 5 such that the liquid level of the liquid 28 in the second tank 5 is the same as the liquid level of the liquid in the chamber 23. The other end of the third end cap 10 is rotatably coupled to the support base 19 by a bearing structure. Further, a duct housing 13 is provided on the support base 19. The duct casing 13 is provided in a cylindrical structure through which both ends pass, and passes through the third end cover 10 and the second end cover 9 into the attachment chamber 23 between the second end cover 9 and the third end cover 10. A conduit 15 is provided within the catheter housing 13 that is movable along the catheter housing. As an embodiment, the outer end of the catheter 15 extends from the catheter housing 13 and is coupled to the actuator 11, while the inner end of the catheter 5 extends into the liquid within the attachment chamber 23. The actuator acts to deepen the inner end of the catheter 15 into the liquid located within the attachment chamber 23 or pull the entire catheter 15 out of the catheter housing 13 to pull the inner end of the catheter 15 to a shallower position in the liquid.

In an exemplary embodiment, the actuator 11 includes a motor 26, a crank 27 mounted on the output shaft of the motor 26, and a connecting rod 12 having one end coupled to the crank 27, the other end of the connecting rod 12 and the conduit 15. The outer ends are connected. With this configuration, the depth of the inner end of the duct 15 into the liquid can be controlled by controlling the rotational direction and the rotational angle of the motor 26. In another embodiment, the actuator may also be an electromagnetic attraction structure or a rack and pinion structure driven by a servo motor. The outer end or side of the catheter 15 can be connected to a catheter, and the other end of the catheter is connected to the inlet tube of the first tank 1. As the inner end of the catheter 15 is inserted into the liquid in the cavities, part of the liquid will flow into the catheter 15 due to the centrifugal force and flow into the first casing 1 through the catheter. It can be understood that the deeper the inner end of the duct 15 is inserted into the liquid 28, the more liquid 28 is discharged from the duct 15, and the less liquid remaining in the second tank 5, the liquid that can enter the bucket wheel 25. The less the rotation speed of the bucket wheel 25 is increased, the lower the rotation speed of the output shaft 14 is. When no liquid 28 is present in the bucket wheel 25, the bucket wheel 22 will rotate synchronously with the output shaft 2 and rotate, and the output shaft 14 will stop rotating, thereby achieving a soft disengagement between the input shaft 2 and the output shaft 14. Therefore, in this embodiment, by adjusting the depth of the inner end portion of the duct 15 into the liquid by the actuator, the rotational speed of the output shaft 14 can be adjusted, and the output shaft can be never rotated, gradually rotated, finally reached and input. The shaft rotates completely synchronously.

Further, the liquid guiding tube may be provided with a filtering device and/or a cooling device, and the outer end of the conduit 15 may also be closed. The conduit ₁₅ and the conduit housing ₁₃ are respectively provided with oil outlet holes, and the liquid 28 is discharged. The hole flows back into the first case 1. It will be appreciated that in this configuration, the catheter housing 13 can also be omitted, and the catheter 15 can be inserted directly into the attachment chamber by providing an opening in the second end cap and the third end cap.

In summary, the invention adds a catheter, a catheter housing, an actuator, a connecting rod, a third end cap, a third end cap and a second end, based on the "hydraulic synchronizer" of the patent number 2006100698771. The cover and the bearing housing form an attachment chamber 23, and the attachment chamber communicates with the second housing and is formed as a working chamber. The conduit 15 is free to move under the driving of the electric actuator. When the conduit 15 extends into the attachment chamber 23, due to the working chamber The pressure difference between the centrifugal force of the liquid and the centrifugal force of the liquid in the first tank 1 allows the liquid to be quickly discharged through the conduit 15 into the tank, so that the oil in the working chamber can be quickly evacuated, thereby disengaging the power; When the conduit 15 is pulled out of the liquid level of the working chamber, it is not in the second tank 5 The oil supply is disconnected, and the power transmission between the input shaft 2 and the output shaft 14 can be quickly joined. When the duct 15 is moved in the above intermediate position, the speed control function can be realized.

In another embodiment, the third end cap 10 can also be disposed on the outside of the first end cap 18. Alternatively, two third end caps 10 may be provided on the outside of the first end cap 3 and the second end cap 9, respectively.

Referring to Figure 5, a second embodiment of the hydrodynamic synchronizer of the present invention is illustrated. Instead of the duct structure in the first embodiment, a spout 29 is provided on the side wall of the second casing 5, and is provided in the first casing 1 or outside the first casing 5 for the second casing 5 The supply device 30 supplies the liquid 28 therein. The supply device 30 is preferably a variable frequency pump. Thus, during operation of the hydrodynamic synchronizer, the opening 29 is always expelling the liquid 28 in the second tank 5, while the variable frequency pump 30 delivers liquid into the second tank 5. If the amount of liquid delivered from the variable frequency pump to the second tank 5 is greater than the amount of liquid discharged from the second tank 5 through the opening 29, the liquid in the second tank 5 is gradually increased, so that the input shaft 2 can be made The output shaft 14 is gradually driven until the two rotate synchronously. If the amount of liquid delivered from the lead pump to the second tank 5 is less than the amount of liquid discharged from the second tank 5 through the port 29, the liquid in the second tank 5 is gradually reduced, so that the output can be made The rotational speed of the shaft 14 is gradually lowered until the rotation is stopped. Therefore, the speed of the output shaft 14 can be adjusted by adjusting the amount of liquid delivered by the variable frequency pump.

Referring to Figure 6, a third embodiment of the hydrodynamic synchronizer of the present invention is shown. In the third embodiment, on the basis of the duct structure of the first embodiment, the duct is fixedly mounted, and the duct 33 connected to the first tank 1 is mounted on the duct 15. The liquid guiding tube 33 is provided with a switch-regulated or continuously-regulating valve device such as a solenoid valve 32. A bypass pipe 34 is connected to the upstream side of the valve 32 of the liquid conduit 33, and the bypass pipe 34 is connected to the second casing 5. Thus, the amount of liquid 28 flowing from the catheter 33 into the second tank 5 can be adjusted by adjusting the temperature of the solenoid valve 32 during operation of the hydrodynamic synchronizer. If the amount of liquid delivered by the supply means and the bypass pipe 34 into the second casing 5 is increased, the liquid in the second casing 5 is gradually increased, so that the input shaft 2 can be gradually driven to the output shaft 14, until both Rotate at the same time. If the degree of opening of the solenoid valve 32 is increased, the amount of liquid delivered by the supply means and the bypass pipe 34 into the second casing 5 is reduced, and the liquid in the second casing 5 is gradually reduced, so that the output shaft 14 can be made. The speed of the speed gradually decreases until it stops rotating. Therefore, by adjusting the twist of the solenoid valve 32, the rotational speed of the output shaft 14 can be adjusted. Alternatively, a solenoid valve 31 may be disposed on the delivery line of the supply device 30 to the second tank 5, and the working chamber may also be changed by changing the degree of twist of at least one of the electromagnetic valve 31 and the solenoid valve 32. The liquid level of the liquid 28. Further, the supply device 30 can also be selected as a variable frequency pump.

In a further embodiment, a conduit is disposed in the attachment chamber 23, and a first electromagnetic reversing valve is installed in the catheter of the catheter. The catheter is divided into two paths by the first electromagnetic commutation, one path and the first box. Body 1 is connected, the other is connected to the second case 5 connected. On the other hand, the liquid supply line of the supply device is provided with a second electromagnetic reversing valve, and the liquid supply line is divided into two paths through the second electromagnetic reversing valve, one way is connected with the first box 1 and the other is connected to the second box. Body 5 is connected. With this structure, the following operation can be realized by controlling the electromagnetic reversing valve according to the feedback signal from the load and the actual needs:

When the working liquid in the conduit returns from the liquid guiding tube to the first tank 1 via the electromagnetic reversing valve, and the liquid supply line of the supply device flows to the first tank 1 through the first electromagnetic reversing valve, the second tank The liquid in 5 is reduced, and the output speed of the output shaft 14 is lowered; when the working liquid in the conduit flows from the liquid guiding tube through the first electromagnetic switching valve to the second tank 5, and the supply line of the supply device passes through the second When the electromagnetic reversing valve flows to the first tank 1, the liquid in the second tank 5 does not change, and the output speed does not change; when the working liquid in the duct passes from the liquid guiding tube to the second box through the first electromagnetic reversing valve When the liquid supply line of the supply device flows to the second tank 5 via the second electromagnetic reversing valve, the liquid in the second tank 5 increases, and the output speed of the output shaft increases. Thereby, the speed regulation process of the multiple output shaft is realized.

The invention is particularly applicable to high power fans, water pumps, conveyor belts and the like.
