Gear shaft rotation stopping device

Abstract

The invention belongs to the field of assembling auxiliary tools, and particularly relates to a gear shaft rotation stopping device. The gear shaft rotation stopping device comprises a rotation stopping base. The rotation stopping base is provided with a circular containing groove, and the circular containing groove is used for containing a gear shaft. An installing through hole is formed in the rotation stopping base and communicates with the circular containing groove. The center axis of the installing through hole is perpendicular to the center axis of the circular containing groove. A rotation stopping pin is arranged in the installing through hole and can move back and forth along the center axis of the installing through hole so as to stretch into the circular containing groove to beengaged with or disengaged from a gear of the gear shaft. The gear shaft rotation stopping device can achieve locking of the gear of the gear shaft according to needs, accordingly, rotation stoppingof the gear shaft is achieved, and lock nut screwing is convenient.

Description

technical field [0001] The invention belongs to the field of assembly aids, in particular to a gear shaft anti-rotation device. Background technique [0002] After the gear shaft of the gearbox is assembled, a lock nut is provided at the rear end to ensure the installation position of each transmission gear and bearing, but when the lock nut is tightened, the gear shaft will rotate with the force of the lock nut , causing the lock nut to fail to tighten. [0003] In the prior art, the shaft of the gear shaft is often locked by means of a special wrench tool, so as to realize the locking of the lock nut. [0004] The shaft of the wrench locking gear shaft in the prior art has the following defects and deficiencies: [0005] 1. Lock the shaft of the gear shaft with a wrench, the friction force cannot be guaranteed, it is easy to slip, and the rotation of the gear shaft cannot be effectively avoided; [0006] 2. Manually locking the shaft of the gear shaft with a wrench is t...

AI Technical Summary

Problems solved by technology

[0005] 1. Lock the shaft of the gear shaft with a wrench, the friction force cannot be guaranteed, it is easy to slip, and the rotation of the gear shaft cannot be effectively avoided;

[0006] 2. Manually locking the shaft of the gear shaft with a wrench is time-consuming and laborious, which affects the assembly efficiency of the gear shaft;

[0007] 3. To achieve the locking of gear shafts of different thicknesses, it is necessary to configure wrenches of different sizes, which increases the number of spare parts
