Vibration locknut assembly and machining method thereof

Abstract

The invention discloses a vibration locknut assembly and a machining method thereof. The vibration locknut assembly comprises a first outer hexagonal part and a second outer hexagonal part, the innerwall of the first outer hexagonal part is provided with a shaft axis and a first internal thread eccentrically distributed on the shaft axis of the first outer hexagonal part, and the outer wall of one end of the first outer hexagonal part is provided with a shaft axis and a cylindrical surface coinciding with the shaft axis of the first internal thread; a first external thread is arranged on thecylindrical surface, a shaft axis, a second internal thread eccentrically distributed with the shaft axis of the second external hexagonal part and an inward-protruding limiting part arranged at one end of the inner wall of the second external hexagonal part are arranged in the axial direction of the second external hexagonal part, wherein the shaft axis of the inward-protruding limiting part coincides with the shaft axis of the second internal thread; and a gasket is arranged between the end surface of the end, provided with the cylindrical surface, of the first outer hexagonal part and the inner end surface of the inward-protruding limiting part, the end, away from the inward-protruding limiting part, of the second outer hexagonal part is sleeved with the cylindrical surface, the first outer thread is in threaded connection with the second inner thread, and an annular matching surface perpendicularly connected with the cylindrical surface is arranged on the outer wall of the first outer hexagonal part.

Description

technical field [0001] The invention relates to a vibration lock nut assembly and a processing method thereof. Background technique [0002] In the construction of high-speed railway track, in order to connect and fix the rail and the substructure (sleeper rail, backing plate) so that the track forms a stable and reliable overall structure, fasteners such as nuts and bolts are often used for fixing, and in order to make the track have a shock-absorbing effect , there will be a spring bar under the nut. However, due to the large vibration of the high-speed railway track, it is very important to prevent the fasteners from retreating and loosening. Once the fasteners become loose, it will affect the integrity and stability of the track structure. [0003] There are many inventors who design to lock the nut by means of gaskets, but there is still room for further improvement in the locking stability of this way. Contents of the invention [0004] The object of the present in...

However, due to the large vibration of the high-speed railway track, the anti-loosening of the fasteners is very important. Once the fasteners loosen, it will affect the integrity and stability of the track structure

[0003] There are many inventors who have designed the lock of the nut by using the washer method, but there is still room for further improvement in the locking stability of this method
