Analysis of Common Problems of Worm Gear Reducers

Worm gear reducers may encounter some common problems during use. The following are these problems and their possible causes:

1. Heat generation and oil leakage of reducers: Due to the combination of non-ferrous metal worm gears and harder steel worms, reducers generate a lot of heat during operation. If the material matching is unreasonable, the meshing surface quality is poor, the lubricant selection or addition amount is incorrect, or the assembly quality is poor, gaps may form, which may lead to oil leakage. In addition, the ambient temperature will also affect the viscosity of the oil and increase the risk of leakage.

2. Worm gear wear: The worm gear is usually made of tin bronze, and the worm is hardened with 45 steel. When the reducer is operating normally, the worm acts like a "file" to wear the worm gear. If the wear is too fast, it may be caused by factors such as inappropriate selection, overload operation, material problems or poor assembly quality.

3. Wear of small helical gears: In vertically installed reducers, the wear of small helical gears is mostly due to insufficient lubricating oil and improper selection. When the machine is stopped, the oil is lost, and there is a lack of effective lubrication during startup or operation, which can easily lead to gear wear. Ensuring proper lubrication is key to preventing this problem.

4. Bearing damage: Bearing damage in the reducer is common due to oil deterioration, which may be caused by moisture generated by the gear oil during hot and cold changes, causing rust and corrosion. In addition, the quality of the bearings and the assembly process are crucial to preventing such problems.

Extended information
The worm gear reducer is a power transmission mechanism that uses a gear speed converter to reduce the number of revolutions of the motor to the desired number of revolutions and obtain a larger torque. Among the mechanisms currently used to transmit power and motion, the range of applications of reducers is quite wide.
