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.

安装前确认电机和减速机是否完好无损，并且严格检查电机与减速机相连接的各部位尺寸是否匹配，这里是电机的***凸台、输入轴与减速机凹槽等尺寸及配合公差。

Before installation, confirm whether the motor and reducer are in good condition, and strictly check whether the size of each part of the motor connected to the reducer is match. Here is the size and fit tolerance of the motor's locating lug, input shaft and reducer groove.

减速机内部齿面硬度 随着齿轮硬齿面技术的发展，其承载能力大、体积小、重量轻、传动精度高等特点使其应用领域日趋广泛。但为获得硬齿面采用的渗碳淬硬使齿轮产生变形，导致齿 轮传动噪声增大，寿命缩短。

With the development of hard tooth surface technology, the internal hardness of gear reducer has been widely used because of its large bearing capacity, ***all volume, light weight and high tran***ission accuracy. But the carburizing and hardening used to obtain the hard tooth surface causes the deformation of the gear, which results in the increase of the noise of the gear tran***ission and the shortening of the service life.
