Installation and maintenance of reducer of CNC plasma cutting machine

The speed reducer of the CNC plasma cutting machine is equivalent to the joints of the human limbs. In order to pay more attention to the maintenance of the reducer, the following is an introduction to the installation and use of the CNC plasma cutting machine reducer:

1. During the installation and debugging of the CNC plasma cutting machine, 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 use compensation of the coupling used. Good alignment can extend the service life and obtain the ideal transmission efficiency.

2. When installing the transmission parts on the output shaft, it is not allowed to strike with a hammer. Usually, the assembly fixture and the internal thread on 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 best not to use steel fixed couplings. Improper installation of such couplings will cause unnecessary external loads, resulting in early damage to the bearings, and even serious damage to the output shaft.

3. The reducer should be firmly installed on a stable level foundation or base, the oil in the oil drain should be able to be drained out, and the cooling air circulation should be smooth. The foundation is unreliable, causing vibration and noise during operation, and causing damage to bearings and gears. When the transmission coupling has protrusions or gears and sprockets, it should be considered to install protective devices. When the output shaft bears a large radial load, the reinforced type should be selected.

4. The installation device according to the regulations ensures that the staff can easily get close to the oil mark, vent plug, and oil drain plug. After the installation is in place, the accuracy of the installation position should be fully checked in order, and the reliability of the tightening of each fastener should be able to rotate flexibly after installation. The reducer adopts oil pool splash lubrication. Before the operation, the user needs to remove the screw plug of the vent hole and replace it with a vent plug. According to different installation positions, and open the oil level plug screw to 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. The test run shall not be less than 2 hours. The operation should be stable without shock, vibration, noise, and oil leakage, and should be eliminated in time if any abnormality is found.

After a certain period of time, the oil level should be checked again to prevent possible leakage from the cabinet. For example, when the ambient temperature is too high or too low, the grade of lubricating oil can be changed.
