Gear reducers are widely used in metallurgy, mining, lifting, transportation, cement, construction, chemical, textile, printing and dyeing, pharmaceutical and other fields. Next, Weigao Transmission will tell you the precautions for installing gear reducers.

1. When installing the gear reducer, attention should be paid to the centering of the transmission center axis, and the error should not be greater than the compensation amount of the coupling used. Good alignment can prolong service life and obtain ideal transmission efficiency.

　　2. When installing the transmission part on the output shaft, it is not allowed to hit with a hammer. Usually the assembly fixture and the internal thread of the shaft end are used to press the transmission part in with bolts, otherwise it may cause damage to the internal parts of the reducer. It is best not to use a rigid fixed coupling, because improper installation of this type of coupling will cause unnecessary external loads, which will cause early damage to the bearing, or even break the output shaft in severe cases.

　　3. Install according to the specified requirements to ensure that the staff can easily approach the oil mark, vent plug, and oil drain plug. After the installation is in place, the accuracy of the installation position should be comprehensively checked in order, the reliability of the pressing of the fasteners, and it should be able to rotate flexibly after installation. The gear reducer adopts oil pool splash lubrication. Before operation, the user needs to remove the screw plug of the vent hole and replace it with the vent plug. Check the height of the oil level line by opening the oil level plug screw according to different installation positions. Add oil from the oil level plug until the lubricating oil overflows from the oil level plug screw hole. Load test run, the time shall not be less than 2 hours. The operation should be stable, without impact, vibration, noise and oil leakage. Any abnormality should be eliminated in time. After a certain period of time, the oil level should be checked again to prevent possible leakage from the casing. If the ambient temperature is too high or too low, the brand of lubricant can be changed.
