在运转200~300小时后，应进行换油，在以后的使用中应定期检查油的质量，对于混入杂质或变质的油须及时更换。一般情况下，对于长期连续工作的减速机，按运行5000小时或每年一次更换新油.

After running for 200~300 hours, the first oil change should be done. The quality of the oil should be checked regularly in later use, and the oil mixed with impurities or deterioration must be changed in time. In general, for a long-term continuous working reducer, new oil is replaced at 5000 hours or once a year.

反力矩支架的安装：反力矩支架应安装在减速机朝向的工作机的那一侧，以减小附加在工作机轴上的弯矩。 反力矩支架与固定支承联接端的轴套使用橡胶等弹性体，以防止发生挠曲并吸收所产生的转矩波动.

Reverse torque support installation: the reverse torque bracket should be installed on the side of the working machine facing the reducer in order to reduce the additional bending moment on the working shaft. The rubber and other elastomers are used in the shaft sleeve of the reverse torque bracket and the fixed support junction to prevent the flexure and absorption of the torque ripple.

减速机内部齿轮齿形修整（修缘和修根）和齿顶倒角 将齿顶的齿形切削成比正确的渐开曲线略呈凸形。当齿轮齿面受外力产生变形时，可以避免对与之啮合的齿轮产生干涉，并且可以降低噪音，延长齿轮寿命。

The internal gear of the reducer is trimmed (trim and trim) and tooth top chamfering to make the tooth shape of the tooth top  convex than the correct involute curve. When the gear tooth surface is deformed by external force, it can ***oid interference to the gears engaged with it, and can reduce noise and prolong the service life of gears.
