Description

Variable-tooth type locknut

Technical Field

The utility model relates to a locking work piece technical field specifically is a become tooth type locknut.

Background

The threaded connection is the connection mode which is most frequently used and most widely used in mechanical products. People put forward more and more high demand to threaded connection reliability in the use, when dynamic vibration, easily produce the displacement between the threaded connection is vice, and "not hard up" phenomenon promptly leads to the vice pine of threaded connection to take off, and especially the screw lead angle is the bigger, and the possibility of "not hard up" is also bigger, causes equipment to break down very easily, can cause the accident when serious. At present, after the bolt connection is completed, the locknut is fixed through modes such as chemical gluing or welding, and the like, so that the locknut achieves the effect of locking.

The prior art developed a modified-profile release nut, such as one of CN204127074U, which changed the angle of the profile so that the normal force generated by the contact applied between the threads was 60 ° to the bolt axis, rather than 30 ° as in the case of the conventional threads. The normal pressure of the variable-thread type thread is far greater than the fastening pressure, so the generated anti-loosening friction force is increased, but the anti-loosening friction force has the following defects in the use process, the anti-loosening nut is screwed on the bolt, and when the anti-loosening nut needs to be disassembled, the thread slipping phenomenon easily occurs on the anti-loosening nut, so that the thread on the anti-loosening nut is damaged, and the subsequent use of the anti-loosening nut is influenced.
