Abstract
The invention discloses a self-locking nut which comprises a nut. The edge of the nut is polygonal, and the upper end surface and the lower end surface of the nut are concave curved surfaces which are revolution surfaces; the revolution center of the revolution surface is positioned on the axis of a screw hole of a self-locking nut, and the revolution surface can be a cylindrical surface, a spherical surface or a double-curved surface; the edge of the polygon is a regular hexagon or a regular quadrangle; the self-locking nut is made of spring steel or tool steel; and the spring steel is 65Mn. The self-locking nut can be locked by the elastic deformation of the nut without affiliated accessories, so that the self-locking nut is convenient to use, preferably adopts symmetrical curved surfaces as two end surfaces, can realize the function of locking by frontal and reverse installation, has no requirement on the engineering level of workers, and enables the stress on the self-locking nut to be uniform so as to avoid the concentration of stress.
Description
Technical field
The present invention relates to a kind of engineering nut, especially a kind of self-locking nut.
Background technique
Bolts and nuts are widely used in various fields as a kind of fastening piece commonly used.Nut is installed for a long time, can be because the vibration of fastener or move, and become flexible.
Usually prevent nut loosening with the fastening mode of double nut in the engineering, but double nut is the thickening of single nut, can not really plays the locking effect of locking.
Existing other self-locking nuts add to adorn other accessory, add pin or steel ball as groove, with the location card nut cap, can cause operation to nut, or nut adds compression spring, and the distortion dynamics of compression spring causes coupling mechanism force not enough inadequately, or in the nut end face machined grooves, groove easily forms stress and concentrates, and causes crackle or cracking.Simultaneously, the increase of accessory also can make the using method complexity, strengthens labor strength, has improved processing cost.
The binding nut of existing national Specification, the shell-type nut that is stamped to form for steel disc, though this kind nut is saved material, easily manufactured, but because workman's technical merit is uneven, very easily nut is oppositely installed, can't play the self-locking effect fully, material is uneven on the market simultaneously, and the locking effect is also uneven, and sheeting material also causes this kind nut strength not enough.
Summary of the invention
The present invention has overcome aforesaid the deficiencies in the prior art, and a kind of self-locking nut is provided.
The self-locking nut comprises nut, and the nut edge is a polygonal, and the nut upper and lower end face is the depression curved surface.
Described depression curved surface is a turning surface, and its gyration center is positioned on the self-locking nut screw axis, and turning surface is cylndrical surface, sphere or hyperboloid.Described polygon edge is regular hexagon or square.Described polygon edge is a regular hexagon.Described self-locking nut material is spring steel or tool steel.Described spring steel is 65Mn.
The present invention realizes locking by the resiliently deformable of self-locking nut.In use, plain nut is installed earlier, the self-locking nut among the present invention is installed outside plain nut, after tightening, because the depression of self-locking nut end face, coupling mechanism force will make self-locking end face generation resiliently deformable, and the self-locking nut tightens bolt locked.Self-locking nut of the present invention needn't accessory, and is locked, easy to use by himself resiliently deformable, and both ends of the surface are preferably symmetroid, and promptly positive and negative installation all can realize locking function, to the no requirement (NR) of workman's technical merit, make the stressed even of self-locking nut itself simultaneously, avoid stress to concentrate; Preferred regular hexagon nut edge, the opening size of its setting tool such as spanner is identical with plain nut, makes the nut setting tool unified, enhances productivity; Preferred 65Mn spring steel material makes the self-locking nut have the certain elastic deformation ability under the prerequisite of intensity satisfying, and can not crack cracking in the course of the work.
Description of drawings
Fig. 1 is the structural representation of self-locking nut.
Embodiment
As described in Figure 1, the self-locking nut comprises nut 1, and the nut edge is a polygonal, and the nut upper and lower end face is the depression curved surface.
Described depression curved surface is a turning surface, and its gyration center is positioned on the self-locking nut screw axis, and turning surface is cylndrical surface, sphere or hyperboloid.Described polygon edge is regular hexagon or square.Described polygon edge is a regular hexagon.Described self-locking nut material is spring steel or tool steel.Described spring steel is 65Mn.
Orthohexagonal nut edge can make instrument unification in the installation process, and number of tools reduces, and reduces production costs, and enhances productivity.The nut upper and lower end face is easy to process for symmetry depression cylndrical surface makes, and distortion evenly reduces the stress of self-locking nut and concentrates; The self-locking nut material is spring steel 65Mn, and 65Mn is used for making small spring more, is used for making the self-locking nut herein, can determine that the self-locking nut has the high elasticity performance satisfying under the prerequisite of intensity, utilizes its resiliently deformable to realize locking.
