Threaded connecting mechanism capable of preventing looseness and transmitting torque

Abstract

The invention relates to a threaded connecting mechanism capable of preventing looseness and transmitting torque. The threaded connecting mechanism is located at the joint of a rotor shaft and a structural arm; the shaft end of the rotor shaft is connected with the structural arm through a threaded structure, and the shaft end of the rotor shaft is internally provided with a set screw, wherein theset screw is arranged to be parallel to the axis of the rotor shaft in a non-collinear mode; and the front end of the set screw abuts against the structural arm so as to lock the rotor shaft and thestructural arm, so that mutual rotating at the joint of the rotor shaft and the structural arm is prevented. The threaded connecting mechanism capable of preventing looseness and transmitting torque solves the problem of looseness preventing of threaded connection, and meanwhile, any opening hole cannot be seen on the outside. Compared with the looseness preventing method by using threaded adhesive, looseness preventing through the threaded adhesive usually prevents freely loosening of a screw and a nut and cannot transmit the torque, the threaded connecting mechanism capable of preventing looseness and transmitting torque can bear the repetitive torque transmitted by the rotor shaft, and non-loosening is ensured; and meanwhile, compared with a mode that the side wall face of an internal thread sleeve directly adopts the set screw for locking, the threaded connecting mechanism does not destroy the overall coordination feeling and has the advantages that the appearance is attractive, and looseness preventing is reliable.

Description

technical field [0001] The invention relates to the field of threaded connection mechanisms, in particular to a threaded connection mechanism that is anti-loosening and can transmit torque. . Background technique [0002] Generally, threaded connections must be anti-loosening, and the anti-loosening requirements are different in different applications. In the connection between the rotor shaft and the structural arm of the hand-held stabilizer, a threaded connection can save a lot of space. Since the rotor transmits torque to the structural arm, a threaded connection mechanism that can prevent loosening and transmit torque is very important. [0003] There are two common anti-loosening methods for threaded connection mechanisms. One is to drill and tap on the vertical wall surface of the internal threaded sleeve of the structural arm, and use the side of the machine screw to withstand the thread to prevent loosening. The other is to use the thread Glue to prevent loosening...

AI Technical Summary

Problems solved by technology

However, drilling and tapping on the vertical wall surface of the internal thread sleeve of the structural arm, and using the side of the machine screw to withstand the thread for anti-loosening will cause the anti-loosening threaded hole to be exposed and destroy the overall aesthetic feeling; the use of thread glue for anti-loosening method, can only prevent free loosening, and cannot reliably transmit the repeated torque of the rotor shaft to the structural arm
