Design of Axle Gear Case in Tunnel Traction Locomotive Based on Rigid-flexible Coupling Model by Using Romax

Blog Article

The rigid-flexible coupling model of axle gear case in tunnel traction locomotive which included the flexible axle and case body was established using Romax, Inventor and Hypermesh software.Tooth profile modification, gear-tooth fatigue strength, bearing life, and the static strength and modal of orly artificial sweetener case body were calculated and analyzed by applying load spectrum to the rigid-flexible coupling model, in which the effects of the flexible deflection, bearing clearance and misalignments were detected and considered.The calculation results and actual practice showed that the rigid-flexible coupling model of axle gear case could be used ww2 glider infantry uniform for developing the product in the design work.
