A wiper motor assembly process

Abstract

The invention provides a novel wiper motor assembly process. The assembly process includes A, motor gear oiling process; B, gear and worm fast running-in process; C, put the run-in worm into the gear and its supporting motor that have been coated with lubricating oil in step A, and assemble it into a gear-worm motor linkage mechanism. The new wiper motor assembly process of the present invention has the characteristics of high degree of automation, thorough and even oiling, stable and reliable oiling quality, simple and easy structure, low cost, etc., and the metal gear and the worm can be meshed and run-in, and the worm root can be removed Round burrs, while achieving the best meshing fit, can make the plastic gears fit into the best meshing state. Improve the noise here by more than 50%, and increase the overall life of the motor by about 10%.

Description

technical field [0001] The invention relates to the mechanical field, in particular to an assembly process of a wiper motor. Background technique [0002] In recent years, my country's automobile market has developed very rapidly. The annual car sales volume has reached more than 20 million vehicles, and more than 22 million automobiles have been manufactured. Correspondingly, more than 23 million kits have to be produced for each automobile component as a wiper assembly system. In general, the quality of the motor and gear itself is very important. At present, adding grease to motor wheel surfaces in the industry is still manually added and applied, which is complicated to operate, high in labor costs, and low in efficiency. Moreover, the worm has not been run-in in advance, and the plastic gear and the worm are assembled before running-in in normal operation, resulting in high noise at the joint between the worm and the gear, and affecting the pass rate of the product at t...

AI Technical Summary

Problems solved by technology

At present, adding grease to the surface of motor wheels in the industry is still manually added and applied, which is complex in operation, high in labor costs, and low in efficiency.

In addition, the worm has not been run-in in advance, and the plastic gear and worm are assembled before running-in in normal operation, resulting in high noise at the joint between the worm and the gear, and affecting the first-time pass rate of the product

[0003] In addition, because the grease on the gear box is directly applied to the gear surface with simple tools, the amount of grease added will be different due to different personal operation methods, and the grease will be applied unevenly or the grease will leak out, resulting in some parts without grease lubrication. There will be abnormal noise during the process, which will affect the entire motor life cycle after a long time
