This standard specifies the type, size and technical requirements of five series of roller motor reducers: YZD, YGL, YZL, YGX and YZX. This standard is mainly applicable to single insecticide drive transport rollers of rolling mills (transmission ratio i ≤ 12.5) and continuous casting machines (i ≥ 2). Its load characteristics are frequent starts, starting with load, and running in both forward and reverse directions. It can also be used for other mechanical transmissions with similar or lighter loads. The working environment temperature is -40~50℃; when it is lower than 0℃, preheating should be done before starting; when it is higher than 40℃, cooling measures should be taken.

5.5.1 Reducer Gear Lubrication and Cooling
5.5.1.1YZI) series are lubricated with calcium-based grease. YGI., YZL, YGX, and YZX series generally use medium extreme pressure gear oil N220 or NV320 for diffuse oil lubrication. The oil immersion depth is 2~~2.5 tooth heights at the top of the high-speed large gear or the internal ring gear of the planetary transmission. For occasions where the ambient temperature is high, circulating oil lubrication can also be used, with oil entering through the ventilation cover and oil returning through the oil drain hole. 5.5.1.2 New reducers that use oil pool flood oil lubrication must be replaced with new oil after 15 to 20 days of operation; under normal circumstances, the oil should be changed once every 5 to 6 months.
5.5.2 The lubrication method of reducer bearings is the same as the lubrication of lubricating oil and gears. 5.5.3 The reducer gear lubricating oil must not penetrate into the motor. 5.6 Testing and Acceptance
