Anti-loosening safety device for power gear

Abstract

The invention discloses an anti-loosening safety device for a power gear. The anti-loosening safety device comprises a locking mechanism mounting plate and a locking mechanism, wherein the locking mechanism mounting plate is mounted on the outer end surface of a power gear; the power gear is mounted on the output shaft of a motor through a bolt; the bolt comprises a screw and a screw head part; the screw head part is an external hexagonal structure or an internal hexagonal structure; the locking mechanism comprises a one-way rotary wheel, an axial protective plate, an eccentric cam, a tensionspring and a force sensor; and a hexagonal hole which is matched with the external hexagonal structure or a hexagonal lug boss which is matched with the internal hexagonal structure is arranged on theone-way rotary wheel. The anti-loosening safety device for the power gear is simple in structure, is convenient to operate, and can lock a connecting gear with the bolt on the output shaft of the motor to prevent the bolt from rotating and loosening, so that the power gear is not separated from the output shaft of the motor, potential safety hazards are avoided, repeated utilization can be achieved, the cost is low, and maintenance is convenient.

Description

technical field [0001] The invention relates to an anti-loosening safety device, in particular to a power gear anti-loosening safety device, which belongs to the technical field of bolt anti-loosening. Background technique [0002] Gear transmission is the most widely used form of transmission in mechanical transmission. Its transmission is relatively accurate, high in efficiency, compact in structure, reliable in operation, and long in life. Common gear transmissions include gear and rack meshing transmission, and gear and gear meshing. As a power gear, it is generally installed on the motor through bolts. On the output shaft, such as in the automobile welding workshop, the movement of the body-in-white stamping parts in the spatial position is largely achieved by the reciprocating conveying trolley. Due to the various advantages of gear transmission, the conveying trolley mainly uses rack and pinion For transmission, the usual method is to fix the rack, and the length of ...

AI Technical Summary

Problems solved by technology

However, in the welding workshop, as the running time is too long, it is inevitable that a small amount of welding slag will adhere to the meshing surface of the rack and pinion, which will not only reduce the service life of the gear, but also cause the rack and pinion to run stuck, with shock and vibration. The connection with the motor shaft is realized by only one bolt. Although spring washers are installed on the bolts, there are still bolts loosening, which eventually makes the gear and the output shaft of the motor disengage, causing equipment failure, delaying production, and causing huge economic losses.

[0004] Facing the above problems: 1. In the body-in-white welding workshop of automobiles, sparks splash, and welding slag particles can bypass the protective cover and adhere to the meshing surface of the rack and pinion

2. During the rack and pinion transmission process in the middle and later stages of the project, because the meshing surface is not smooth, there is always impact and vibration during transportation, causing the bolts to loosen

If the bolts are loose and allowed to develop, it may eventually cause the gears to fall off, resulting in no power control of the equipment, causing a huge safety accident
