How to Clean and Maintain the Planetary Gearbox ？
First parts
After using the gearbox on this reducer for a period of time, clean and maintain it. Cleaning and maintenance can make the inside cleaner and cleaner, which means that the gears can ensure better operation during operation, achieve better lubrication, minimize friction, and better performance,
Second parts
Second partsThere may be slight wear on the gears inside. It is necessary to check the wear of the gears inside the gearbox. If the wear is within an acceptable range, then the gear can still working. If the wear is already severe, a certain tooth inside needs to replace. After maintenance is complete, add the lubricating oil to the equipment, and the lubricating oil to this equipment has relevant requirements. This lubricating oil should be selected according to the standards in the manual so that a matching lubricating oil can be used to repair this gear. In addition, the lubricating oil inside this gearbox may become contaminated after being used for a period of time, so it is necessary to regularly replace the inner wheel lubricating oil during maintenance.
The last
Another task that needs to be done during maintenance is to inspect the transmission shaft inside the gearbox, because the transmission shaft plays a role in bearing a large amount of load during actual use. After a long time of use, it is necessary to check whether the transmission shaft can still be used normally. During inspection, many aspects need to be examined, For example, if there are obvious scratches or cracks on the external appearance of the transmission shaft inside the inspection, it is possible that the transmission shaft has already been damaged. At this time, further inspection is necessary. If the inspection is not carrying out, the small sliding marks or cracks may become larger and larger, which will affect the overall use of the equipment.
