齿轮传动系统仿真

Simulation of Gears Transmission System

提出一种新的齿轮误差测量方法,即以实际齿面上的点相对于对应理论齿面上点的法向偏移量为齿轮误差。该误差可以包含齿轮所有误差信息。考虑齿轮对啮合过程中的正常啮合、脱啮和齿背啮合及碰撞的情况建立齿轮传动系统振动数学模型。通过对该模型的分析,探讨了在考虑齿轮传动误差的情况下,作用在该系统的静力矩以及动力矩之间的关系对齿轮对啮合拍击的影响。

The errors of the bevel gear was expressed with a new form, that was the deviation of real tooth surfaces from the theoretical ones were measured by an invented new kind of measuring device. A model was provided for simulating the bevel gear transmission system concerning the time variant stiffness and bevel gears errors under static load and cyclic loads. Through the model the computerized analysis of speed, angle and acceleration of gear real tooth surface could be accomplished. Rattle was discussed under condition of different static loads and the constant cyclic loads.
