Embodiment 1

[0023] In this implementation, the motor motor teeth of the model: FE-ZGR335 are selected for operation, and the motor motor teeth of the model: FE-ZGR335 are ground by the eddy current grinder, and the burrs on the top of the sharp teeth of the motor motor teeth are rounded and smooth. Smooth, the burr height is reduced by 0.04-0.08mm; specifically include the following steps:

[0024] 1) Prepare the vortex grinder and check that all aspects of the vortex grinder are in good condition;

[0025] 2) According to the capacity of the vortex grinder, prepare anti-rust water, abrasive, water and grinding stone in proportion; and the grinding stone can be set to 6*6mm corundum grinding stone or 6*6mm corundum triangular stone ; In this embodiment, 6*6mm corundum triangular stone is selected; and the ratio of antirust water, abrasive and water is set to 1:1:40, and the antirust water and abrasive are both existing technologies, and both use Hengxin Antirust water and abrasives produ...

Abstract

The invention discloses a method for improving abnormal sound of an automobile parking motor gear box. The method is characterized in that an eddy mill is adopted to grind motor teeth in the automobile parking motor gear box, burrs at sharp tooth tops of the motor teeth are machined to be round and smooth, and heights of the burrs are reduced by 0.04 mm to 0.08 mm. Through the method, the burrs on the sharp tooth tops of the motor teeth are machined to be rounder and smoother, the heights of the burrs can be reduced by 0.04 mm to 0.08 mm, meanwhile, meshing precision of gears is greatly improved, and noise and abnormal sound of the gear box are greatly improved after the gears are installed finally; and the method is simple to operate, convenient to use and very suitable for large-scale production, and has high practicability.

Description

technical field [0001] The invention relates to the technical field of gearbox planetary frame welding, in particular to a method for improving the abnormal sound of a gearbox of an automobile parking motor. Background technique [0002] The motor gear PINION GEAR in the prior art is widely used in the gearbox of the automobile EPB system or the gearbox of the sanitary products; in the prior art, according to the requirements of the customer manufacturer, the size and performance of the product can be designed to meet the According to the requirements of the customer's drawings, but the motor teeth of the motor are actually installed in the gearbox of the terminal assembly. During the actual operation, abnormal sounds and noises will be generated. [0003] After many tests and inspections, it is found that the tooth tops of the motor teeth are sharp and have more burrs. The sharp burrs are not convenient to remove through processing, and the sharp burrs will also affect the ...
