1. The internal structure design of the reducer is not standardized
In the structure of the reducer, due to the design of the cover plate above the inspection hole is too thin, it is easy to deform locally after tightening the screw, resulting in contact gaps and oil leakage. During the manufacturing process, the castings are not annealed and deformed, resulting in gaps and oil leakage. It is also possible that because there is no oil return groove on the box body, when too much lubricating oil accumulates on the end cover of the reducer box and the structural joint surface, the pressure difference causes the lubricating oil to leak out from the joint gap.
2. Poor lubrication of gear pair causes tooth surface wear
Due to the harsh operating environment of the reducer, the lubricating oil film is not easy to form and exist stably between the meshing surfaces, resulting in the formation of pitting, friction, wear, and deformation on the gear surface, the bearing chamber, and the gear shaft diameter surface, until the gear surface is seriously damaged. Wear.
3. Oil leakage in the tank causes environmental pollution
In the reducer, oil leaks from the box due to factors such as oil seal damage, gasket damage, loose oil plug, or damaged oil mark. It may also cause excessive oil volume, high oil level, or multiple cold starts to cause lubricating oil. The blistering phenomenon causes a large amount of oil leakage at the vent plug, which seriously pollutes the environment.
4. Vibration and noise cause environmental pollution
After the reducer is started, due to gear and bearing wear, or poor assembly of the transmission device, the machine will vibrate greatly. For reasons such as bearing damage, gear wear, gear damage, or jamming of foreign objects, the machine will emit a loud and long-lasting harsh sound. The occurrence of these faults will cause serious noise pollution.
5. Excessive oil temperature causes device damage
During the operation of the reducer, due to insufficient lubricating oil or overloading of the equipment, the temperature of the lubricating oil inside the reducer rises rapidly, causing partial damage to the relevant parts of the reducer. Some devices have not been eliminated due to internal stress, and large thermal deformation will cause the accuracy of the reducer to decrease, and some devices may be damaged due to reduced material strength under high temperature conditions. In addition, some reducers with inflexible operation and severe power loss during operation may cause the transmission parts to be jammed when foreign objects invade, causing uneven operation or abnormal vibration.
