Research on Precision Forming Process of Starter Reducer Shaft (3)

4. Economic and social benefits

The starter deceleration shaft is precision-formed, the material is dense and the fiber is not damaged, especially the involute internal gear part, which has a continuous flow of metal fiber, which avoids the formation of a knife at the root of the gear during machining. Insufficient marks, micro cracks and surface roughness, which greatly improve the shear strength and service life of the deceleration shaft, and have good social benefits. The automobile starter deceleration shaft produced by the precision forming process shortens the working hours, reduces the waste of tools, fixtures, manpower and material resources, and improves the precision and quality of the products. Therefore, the production cost is greatly reduced and the profit is improved. Significant economic benefits.

5 Conclusion

Precision forming technology is the key technology to improve product performance and quality. It can shorten the manufacturing cycle of products, reduce production costs, and more importantly, improve the accuracy requirements and comprehensive performance requirements of parts. The deceleration shafts that have been mass-produced are proved by process evaluation, installation test, and running-in:

The precision forming process of the deceleration shaft is reasonable, the scheme is correct, the mold design is simple, the gears in the involute inner shaft are well filled, and can be used without machining, and the design requirements of the deceleration shaft of the starter are achieved. Therefore, the precision forming technology of the deceleration shaft has extensive guiding significance and promotion value for mass production of this type of deceleration shaft and other similar parts.
