      Lubrication and maintenance of the reducer: Before putting it into operation, put the recommended model and value of grease into the reducer. The reducer is lubricated with lubricating oil. For the vertically installed reducer, since the lubricating oil may not guarantee the reliable lubrication of the uppermost bearing, additional lubrication measures are adopted.

      Before operation, inject an appropriate amount of lubricating oil into the reducer. The viscosity of lubricating oil is selected according to the following list. The reducer is usually equipped with an oil filling hole and an oil drain plug. Therefore, the installation location must be specified when ordering the reducer. Note: For applications with unconventional working conditions, please consult the manufacturer. The working oil temperature cannot exceed 80°C. The life-time lubricated combination reducer is filled with synthetic oil in the manufacturer. In addition, the reducer is usually supplied without lubricating oil, and comes with an oil filling plug and an oil drain plug. The quantity of lubricating oil for the reducer listed in this catalog is only an estimate. Set the position of the oil level plug according to the installation position specified when ordering to ensure correct oil filling. The oil filling amount of the reducer should be determined according to different installation methods. If the transmission power exceeds the heat capacity of the reducer, an external cooling device must be provided.

Precautions for the inspection and maintenance of the reducer of Jiangsu Changzhou City Heavy Industry Gearbox Manufacturing Co., Ltd.:

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 circulation should 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 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 should be comprehensively checked in order, the reliability of the pressing of the fasteners, and the flexible rotation after installation should be possible. The 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 trial 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 grade of the 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 the 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 rigid fixed coupling, because improper installation of this type of coupling will cause unnecessary external load, which will cause early damage to the bearing, and even cause the output shaft to break in severe cases.
