Abstract
The invention discloses a coding disk of an alternating current induction motor. The coding disk comprises a main coding disk body, wherein a mounting hole connected with a rotating shaft of the motor is formed in the center of the main coding disk body. The coding disk is characterized in that the main coding disk body is of a disc ferrule structure molded once by sheet steel in a stamping manner, a plurality of long slotted holes are formed in one side of the outer circumference surface of the main coding disk body, and a mounting hole with a flange is formed in the center of the main coding disk body. As being molded once by the sheet steel in the stamping manner, the coding disk has a more reasonable structure and is energy-saving and environment-friendly, and the labor cost is also reduced. In addition, original cast steel or round steel is replaced by the sheet steel, so that the material cost is reduced by over 70%, and the coding disk is easy to process, good in consistency and suitable for mass production. The coding disk is simple and reasonable in structure, low in material cost, light in weight and easy to process, and can reduce inertia and noises of a motor rotor in running so as to effectively improve the performance of the motor.
Description
Technical field
The present invention relates to machine field, particularly relate to a kind of AC induction motor coding disk by the outside output pulse signal of external encoder.
Background technology
AC induction motor is as a kind of new technology, is widely applied, just bringing into play great function at industrial vehicles such as the electrocar of modern logistics industry and electri forklifts.
Along with the continuous progress of motor speed control technology, electric industry vehicle is controlled future development from the earliest rheostatic speed regulation control, the control of direct current series-excited motor speed, the control of direct current separately excited machine speed to AC induction motor speed.
The advantage that AC induction motor is the most outstanding is not have carbon brush, its characteristics: efficient is high, volume is little, lightweight, simple in structure, non-maintaining, good heat dissipation, degree of protection height and long service life.But for the rotating speed of controlling AC induction motor with turn to, two phase differences of output are the pulse signals of 90 degree when needing the motor rotation.Majority adopts the methods of external encoder at present, and as shown in Figure 4, this method need to be installed a coding disk at machine shaft, at motor housing an encoder is installed, and encoder just can be exported required pulse signal when motor rotates.
At present, AC induction motor coding disk (as shown in Figure 3) adopts all that cast steel or round steel cut, Gear Milling, and manufacturing procedure complexity, long processing time, material cost and labour cost are high, is not suitable for producing in enormous quantities.
Summary of the invention
Technical problem to be solved by this invention is that a kind of simple and reasonable, the AC induction motor coding disk that the cost of material is low, process velocity is fast is provided for the above-mentioned state of the art, adopt the sheet metal material to replace original cast steel or round steel, not only the cost of material is low, simultaneously handling ease, good product consistency.
The present invention solves the problems of the technologies described above the technical scheme that adopts: a kind of AC induction motor coding disk, it comprises the coding disk main body, the center of described coding disk main body is provided with the installing hole that is connected with machine shaft, it is characterized in that: described coding disk main body is to adopt the one-time formed plate-like ferrule arrangement of steel plate punched, outer circumference surface one side in the coding disk main body is distributed with a plurality of long slot bores, forms the installing hole of a flange at the center of coding disk main body.
As improvement, an end opening of described coding disk main body, the other end form the groove of an annular to the center, inwardly be step-like turnover between the turnover face of installing hole and coding disk main body
Improve, evenly offer a plurality of long slot bores on the outer circumference surface of described coding disk main body, the plane of described long slot bore and described coding disk main body is perpendicular, and is connected with the turnover face of described coding disk main body.
At last, the length of described long slot bore be described coding disk main body the outer circumference surface width 80%～90%, the quantity of long slot bore is decided according to the motor needs.
Compared with prior art, the invention has the advantages that: product is to form by the steel plate punched moulding, so that structure is more reasonable, not only energy-conservation but also environmental protection has reduced labour cost; In addition owing to adopt steel plate to replace original cast steel or round steel, so that material cost reduced more than 70%, and handling ease, good product consistency, be fit to produce in enormous quantities; The present invention is simple and reasonable, the cost of material is low, lightweight and handling ease, also can reduce simultaneously inertia and the noise of rotor when operation, the performance of Effective Raise motor.

Embodiment
Embodiment is described in further detail the present invention below in conjunction with accompanying drawing.
As shown in the figure, a kind of AC induction motor coding disk is installed on the machine shaft of AC induction motor 2 on 3, cooperates with external encoder 4 on being installed in motor 2 shells, and encoder 5 just can be exported required pulse signal when motor 2 rotation; Described AC induction motor coding disk comprises coding disk main body 1, and described coding disk main body 1 is to adopt the one-time formed ferrule arrangement that is plate-like of sheet metal punching press, forms the installing hole 11 of a flange at the center of coding disk main body 1, is connected with machine shaft 3; One end opening of described coding disk main body 1, the other end form the groove 13 of an annular to the center, inwardly be step-like turnover between the turnover face of installing hole 11 and coding disk main body 1; Evenly offer a plurality of long slot bores 12 near turnover face one side on the outer circumference surface of described coding disk main body 1, the length of described long slot bore 12 be described coding disk main body 1 the outer circumference surface width 80%～90%, described long slot bore 12 is perpendicular with the plane of described coding disk main body 1, and is connected with the turnover face of described coding disk main body 1; The quantity of long slot bore 12 is decided according to motor 1 needs.
Described coding disk is when adopting sheet metal to produce, first by stamping die punching blanking, again by the shaping mould punch forming.
The present invention adopts the punch forming of sheet metal material to replace original cast steel or round steel, so that material cost can reduce more than 70%, and handling ease, good product consistency, be fit to produce in enormous quantities.Owing to lightweight, also can reduce inertia and the noise of rotor when operation, the performance of Effective Raise motor simultaneously.
