摘要
目的研究功率封闭机械式变速器齿轮寿命试验台．方法利用定轴式齿轮、传动箱及弹性扭轴进行功率封闭；利用行星传动、谐波传动及计算机控制技术进行动态加减载．结果电气机械加载器加载速度为１２．８ｍｒａｄ／ｓ，试验台功率损失率约５７％．结论功率封闭机械式变速器齿轮寿命试验台可进行动态加载，运转过程中载荷稳定，节能率约４３％，实现了试验过程的自动控制．
Aim To study the powerclosed mechanical transmission gear life test stand Methods Using planetary transmission, harmonic drive, and computercontrol techniques, to realize dynamical loading Using fixedaxes gear trains and an elastic torque axle, to realize powerclosed Results The loading speed of the electrical and mechanical loader is 128 mrad/s, the loss of efficiency of the test stand is about 57% Conclusion Loading could be done dynamically by the powerclosed mechanical transmission gear life test stand, the load is stable under test Saving power efficiency is about 43% The procedure of test is controlled automatically by computer
