To study the dynamic characteristics of spur gears with crack faults, it is essential to establish meshing stiffness model accurately. In this paper, time-varying (TVMS) and load-sharing ratio (LSR) were established by potential energy method, correctness TVMS was verified KISSsoft. The influence gear depth angle on LSR analyzed introducing into model. multi-degree freedom dynamics centralized ...

Ensuring regular movement and power transmission in gear wheels is possible with a suitable tooth profile. Although involute profiles have structure that can provide conjugate accordance the law of gearing, errors cause vibration noise occur due to flexibility elements system under dynamic conditions. Transmission depend-ing on many parameters from production oil lubrication system. In this stu...
