How to check the slew drive?

As a key part of the main engine, whether the slew drive can work normally is related to the operation performance of the main engine. Although the slew drive can be used in different industries, the slew drive will be damaged. If it is found that the rotary drive is damaged in use, we do not know where the damage is. Only comprehensive anatomy can find the damage point.

1.What is slew drive?            

Slewing drive device, also known as rotary reducer, rotary reducer and slewing mechanism, is a modular device with worm or gear, motor or reducer installed on slewing ring. Because of the modular operation, the slew drive device can save the installation time of the user, and the function centralization is convenient for the designer to design the product. At present, it is widely used in industrial robots, solar power generation and other fields.

2.Check the slew drive            

When disassembling the slew drive, the outer ring of the slew drive should be connected with the upper carriage, and the inner ring should be connected with the lower vehicle. The sealing ring on the slew drive should be cleaned and put in place. The equipment should be separated by the well crane, and the screws and bolts on the slew drive should be taken out. Take out the steel ball and isolation sleeve completely, check the steel ball and isolation sleeve. If there is crack or damage on the isolation sleeve, it is necessary to replace it in time. To check the steel ball is to clean the steel ball and put it in the sunlight to see whether there are pits or pits on the steel ball.

3.Maintenance and inspection of slewing drive            

How do we maintain the slewing drive in winter? Maintenance of slew drive in winter should start from the following aspects: when the slew drive leaves the factory, it is coated with a small amount of No. 2 extreme pressure lithium base grease, and the user should refill with new grease according to different working conditions. It should be comprehensive working factors, users can also choose the best grease according to specific requirements.            

The slew drive raceway should be filled with grease regularly. Generally, ball bearings should be oiled every 100 hours and roller bearings should be lubricated every 50 hours. In special working environment, such as tropical, humidity, dust, temperature difference and continuous operation, the lubrication cycle should be shortened. The machine must also be filled with new grease before and after long-term shutdown. The raceway must be filled with grease every time until it seeps from the sealing belt. When filling grease, rotate the slew drive slowly to fill the grease evenly.            

The tooth surface should always be cleaned of debris and coated with corresponding grease. After the first 100 hours of operation of the slew drive, the bolt preload should be checked, and then it should be checked every 500 hours. Sufficient preload must be maintained. Pay attention to the operation of the slew drive during use. In case of noise, impact and sudden increase of power, the machine should be shut down immediately for inspection and troubleshooting. If necessary, it should be disassembled for inspection. It is forbidden to wash the slew drive directly with water to prevent ice and snow from entering the raceway. Strictly prevent hard foreign matters from approaching or entering the gear meshing area. Check the sealing condition regularly. If the sealing bag is damaged, it should be replaced in time. If it is found to fall off, it should be reset in time.

The cold weather in winter will have a certain impact on the normal operation of the slew drive. The above details should be checked in place, kept clean, and prepared for possible situations in advance to improve the service life of the slew drive.
