Common Problems of Worm Gear Reducers - Part 1
Worm gear reducers are transmission machinery with a compact structure, large transmission ratio, and self-locking function under certain conditions. Various problems may also occur during use. Here is an analysis of the causes of some common problems:
Common Problems and Causes:
1. Reducer overheating and oil leakage. To improve efficiency, worm reducers generally use non-ferrous metals for the worm wheel, while the worm is made of harder steel. Due to sliding friction transmission, more heat is generated during operation, causing thermal expansion differences between various parts and seals of the reducer, thus forming gaps at mating surfaces. The lubricating oil becomes thinner due to temperature increase, which easily causes leakage. There are mainly four reasons for this situation: first, unreasonable material matching; second, poor surface quality of the meshing friction surface; third, incorrect selection of lubricating oil amount; fourth, poor assembly quality and usage environment.
2. Worm wheel wear. The worm wheel is generally made of tin bronze, with the paired worm material being 45 steel hardened to HRC45-55, or 40Cr hardened to HRC50-55 and then ground on a worm grinding machine to a roughness of Ra0.8μm. Under normal operation, the wear of the reducer is very slow, and some reducers can be used for more than 10 years. If the wear rate is relatively fast, it is necessary to consider whether the selection is correct, whether it is operating under overload, and reasons such as the material of the worm wheel and worm, assembly quality, or usage environment.

Worm gear reducers are transmission machinery with a compact structure, large transmission ratio, and self-locking function under certain conditions. Various problems may also occur during use. Here is an analysis of the causes of some common problems and corresponding solutions:
Common Problems and Causes:
1. Wear of drive small helical gear. This generally occurs in vertically installed reducers and is mainly related to the amount of lubricating oil added and the oil type. In vertical installation, it is easy to cause insufficient lubricating oil. When the reducer stops operating, the gear oil between the motor and reducer is lost, and the gears do not receive proper lubrication protection. When the reducer starts, the gears experience mechanical wear or even damage due to lack of effective lubrication.
2. Worm bearing damage. When a fault occurs, even if the reducer box is well sealed, it is often found that the gear oil inside the reducer is emulsified, and the bearings are rusted, corroded, and damaged. This is because after the reducer operates for a period of time, condensed water generated from the heating and cooling of the gear oil mixes with water. Of course, it is also closely related to the bearing quality and assembly process.
