Maintenance method

The usage frequency and intensity of each machine are different. Adjust the lubriion cycle appropriately according to your own situation. Another point to note is that the lubriion cycle cannot be too short, otherwise too much oil in the bearing will break the dust ring and cause oil leakage. At the same time, impurities will be mixed into the bearing, which will affect the normal use of the machine.
The frequency of lubriing oil replacement at the rotary motor of the excavator is between the first two, and it is maintained every 1,000 hours.Observe the amount of lubriing oil from the dipstick. When any abnormality is found, check whether there is any lubriing oil leakage.

Theory

The Swing motor is a key component of the excavator's slewing mechanism. It converts the oil pressure provided by the main pump into mechanical energy and inputs it to the reducer. Its working performance will directly affect the rotation speed, driving torque, and rotation of the entire machine. Parking and parking brakes are key to determining the productivity of the entire machine. After the excavator has been working for a long time, the swing motor often appears weak in rotation and unstable in rotation. At this time, it is necessary to replace the internal parts based on the test results.
