Problems solved by technology

However, in practical applications, this type of anti-loosening bolt is still prone to loosening under vibration conditions, which cannot meet actual needs. It is necessary to design a locking component for connecting parts that controls the loosening function to ensure continuous and normal operation of machinery operating under vibration conditions.

Abstract

The invention discloses a bolt anti-loosening structure. The bolt anti-loosening structure is characterized in that the bolt anti-loosening structure comprises a lock bolt, a lock nut and a lock snap spring; the lock nut is screwed into the lock bolt; the lock snap spring is arranged above the lock nut; a lock tongue of the lock snap spring is embedded into a groove of the lock bolt, and a notch of the lock snap spring is embedded into a clamping key of the lock nut; and meanwhile a lock snap spring key is embedded into a groove of the lock nut. According to the anti-loosening bolt method, bolt pretightening force can be controlled within a constant and effective range, connecting parts operating in a vibration state can be effectively connected and safely and normally work, and maintenance operations like mounting and dismounting are made convenient and fast.

Description

technical field [0001] The invention is applicable to a bolt anti-loosening structure and an anti-loosening method for bolts that fail to be tightened due to vibration that loosens the bolts. [0002] technical background [0003] Anti-loosening bolts are mainly used to control the loosening and failure of connecting parts operating under vibration conditions, especially for mechanical equipment such as mining machinery under vibration working conditions, it is necessary to take measures to prevent parts from loosening and affect the normal operation of mechanical connecting parts. The existing anti-loosening bolts use thermal spraying technology to spray special engineering plastics whose main component is nylon on the thread teeth. When the threads are tightened, this layer of engineering plastics is squeezed to generate strong reaction and friction. Thereby preventing the screw from retreating and achieving the effect of anti-loosening. However, in practical applications,...
