Inspection and maintenance of reducer Different lubricating oils are not allowed to be mixed with each other. The positions of the oil level plug, the oil drain plug and the breather are determined by the installation position. Their relative positions can be determined with reference to the installation position diagram of the reducer. Check the oil level • Cut off the power to prevent electric shock! Wait for the reducer to cool down! • Remove the oil level plug to check if the oil is full. • Install the oil level plug. Oil inspection • Cut off the power to prevent electric shock! Wait for the reducer to cool down! • Open the oil drain plug and take an oil sample. • Check the viscosity index of the oil. ——If the oil is obviously turbid, it is recommended to replace it as soon as possible. • For reducers with oil level plugs ——Check the oil level to see if it is qualified. ——Install the oil level plugs. • Cut off the power to prevent electric shock! Wait for the reducer to cool down and there is no danger of burning! Note: The reducer should still be warm when changing the oil. • Place an oil pan under the oil drain plug. • Open the oil level plug, breather and oil drain plug. • Drain all the oil. • Install the oil drain plug. • Inject new oil of the same brand. • The amount of oil should be consistent with the installation position. • Check the oil level at the oil level plug. • Tighten the oil level plug and breather.
Precautions for inspection and maintenance of reducer
1. The reducer should be firmly installed on a stable level foundation or base, the oil in the oil drain groove should be drained, and the cooling air should circulate smoothly. 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 gears or sprockets for transmission, consider installing protective devices. When the output shaft bears a large radial load, a reinforced type should be selected.
2. Install the device according to the regulations 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, the reliability of the pressing of the fasteners, and the flexibility of rotation after installation should be checked in order. The reducer adopts oil pool splash lubrication. Before running, the user needs to remove the screw plug of the vent hole and replace 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 and free of shock, 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.
3. When installing the 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.
4. When installing the transmission parts on the output shaft, it is not allowed to hit with a hammer. Usually, use the assembly fixture and the internal thread of the shaft end to press the transmission parts 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.
