Assembly steps and technical requirements of reducer

1. When installing the reducer, attention shall be paid to the alignment of the transmission center axis, and the error shall not be greater than the use compensation of the coupling used. Good alignment can prolong service life and obtain ideal transmission efficiency.
2. When installing the transmission parts on the output shaft, do not knock them with a hammer. Generally, the assembly fixture and the internal thread at the shaft end are used to press the transmission parts in with bolts, otherwise the internal parts of the reducer may be damaged. It is better not to use rigid fixed coupling, because improper installation of this kind of coupling will cause unnecessary external load, resulting in early damage of bearing and even fracture of output shaft in serious cases.
3. The reducer shall be firmly installed on a stable and horizontal foundation or base, the oil in the oil drain tank shall be drained, and the cooling air circulation shall be smooth. The foundation is unreliable, which will cause vibration and noise during operation, and cause damage to bearings and gears. When the transmission coupling has protrusions or adopts gear and sprocket transmission, it shall be considered to install protective devices. When the output shaft bears large radial load, the reinforced type shall be selected.
4. Install the device according to the regulations to ensure that the staff can easily access the oil standard, vent plug and oil drain plug. After the installation in place, the accuracy of the installation position and the reliability of the compression of each fastener shall be comprehensively checked in order. It shall be able to rotate flexibly after installation. The reducer adopts oil pool splash lubrication. Before operation, the user needs to remove the plug of the vent hole and replace the vent plug. According to different installation positions, open the screw of the oil level plug, check the height of the oil level line, add oil from the oil level plug until the lubricating oil overflows from the screw hole of the oil level plug, screw on the oil level plug, and then conduct no-load test run, which shall not be less than 2 hours. The operation shall be stable without impact, vibration, noise and oil leakage. Any abnormality shall be eliminated in time. The oil level shall be checked again after a certain period of time to prevent possible leakage of the casing. For example, when the ambient temperature is too high or too low, the brand of lubricating oil can be changed.
