KAF97-5.3-A -FL4520 The main reasons for abnormal heating of gear reducers are as follows:
1. Lubrication problem
Insufficient lubricant : Insufficient amount of lubricant inside the reducer will increase friction between gears, bearings and other components, generate too much heat, resulting in excessive temperature rise.
Poor quality of lubricant oil : Use of unqualified quality, aging or deteriorated lubricant will become worse, increasing friction between parts, and causing abnormal heating of the reducer.
2. Load issues
Overload operation : The load borne by the reducer exceeds its rated value, the friction between gears and bearings will increase sharply, heat will accumulate in large quantities, and the temperature will rise rapidly.
Frequent start and stop : Excessive start and stop operations will cause the reducer to bear additional load, resulting in higher temperature rises.
Load fluctuations : The load is unstable and frequently changes, which will cause the reducer to withstand instantaneous overload, thereby increasing temperature rise.
3. The heat dissipation problem
Ambient temperature is too high : If the working environment temperature of the reducer is too high, it will affect its heat dissipation effect, making it difficult to dissipate heat and the temperature rise is too large.
Poor ventilation : The external heat dissipation conditions of the reducer are poor, such as the heat dissipation air duct is blocked or installed in a closed and narrow space, the heat cannot be dissipated into the surrounding environment in time, which will cause the temperature to continue to rise.
4. Internal failure
Gear wear : After long-term use of gears, the wear will be severe and the tooth shape will change, which will increase the friction during meshing and lead to excessive temperature rise.
Bearing damage or wear : The bearing is damaged or worn, which will reduce the operating accuracy of the rotating parts, increase friction, and thus increase the temperature rise.
Poor meshing between gears and bearings : insufficient meshing accuracy of gears and bearings, inaccurate installation, etc., may lead to local overheating and abnormal overall heating of the reducer.
