Research of Reducing Gear Bending Stress based on Multi-parameter Optimization

Autor: Zhao Xiangfei, Cui Yan, Zhang Tianyi

Publikováno v: Jixie chuandong, Vol 42, Pp 31-33 (2018)

Gear is an important part for mechanical transmission. In order to avoid the case of bending fatigue fracture during transmission,with the maximum bending stress of the tooth root as the objective function,and the tooth thickness greater than 0. 25 m

Theoretical Analysis and Quick Calculation of Spur Gear Tooth Deformation

Autor: Zhang Jingcai, Liu Hongqi, Zhao Xiangfei, Yang Chao

Publikováno v: Jixie chuandong, Vol 39, Pp 48-55 (2015)

A quick calculation method of gear tooth deformation based on mechanics of materials,and calculation formulas for each deformation are analyzed and demonstrated. A modified gear tooth basic deformation Weber- Banaschck formula is proposed. The result

Study on Allocation Method of Root Bending Stress based on Gear Tangential Modification

Autor: Cao Yaguang, Zhao Xiangfei, Li Xiuming

Publikováno v: Jixie chuandong, Vol 39, Pp 46-48 (2015)

Gear is an important part for mechanical transmission.For the case of bending fatigue fracture of pinion during the transmission,the gear tooth thickness is reassigned by tangential modification.The center distance and transmission ratio unchanged,th
