Finite Element Analysis and Dynamic Testing for Hard Gear Cutting by Gear Hobbing Machine

Abstract:

While cutting big modulus hard gear with gear hobbing machine YB3180H, the vibration is big and the efficiency is low. To improve this situation, the pulse excitation method is used in analyzing the six steps modal of the gear hobbing machine. Through comparing with the body test modal analysis result, correcting and establishing 3 D ANSYS modal of the body, and the weakness of the machine tool vibration is confirmed by finite element analysis of 3D modal. the theoretical basis can be provided to the machining, the machinery design, improvement and optimization of the machine body.
