Worm gear box is also called worm gear reduction property, mainly composed of worm gear, shaft, bearing, case and so on. Among them, the chassis is used to support other parts of the worm gear box, so it needs to have enough strength to bear the load to avoid deformation and reduce the transmission quality. In order to maintain the transmission quality of the worm gear box, it is necessary to understand the common faults of the worm gear box during use, so as to avoid problems that cannot be solved quickly. 

Trouble of worm gear box:

1. Due to the damage of the polyurethane sealing ring in the small oil cylinder, the pressure oil will enter the worm gear box, causing the pressure oil in the oil filling hole on the top of the worm gear box to emerge, or the height of the lubricating oil will increase

2. The horizontal pin of the push rod of the worm gear box was broken, which made it impossible to drive the clutch disc and the pressure oil output by the auxiliary pump could not meet the requirements.

3. Due to the problem of the worm gear itself, the bearing lacks oil or is damaged, resulting in noise in the worm gear box.

The above are the common faults of the worm gear box. Knowing the cause of the fault, you can find a solution to the problem.
