How to determine whether the heating of the KAT47D90S4/1.1KW/39.6 reducer is normal

Comparative temperature range: Referring to relevant standards and experience, under normal operating conditions, the surface temperature of general industrial reducers is within the normal range of 35℃-85℃. Among them, 35℃-50℃ is the ideal temperature for no-load or light-load operation; 50℃-70℃ is the stable operation interval for medium loads; 70℃-85℃ is the critical safety value for heavy-load conditions. If the temperature of the reducer is within this range and the operation is stable and there are no other abnormal phenomena, then heating is usually normal.

Observe the temperature change trend: You can regularly measure the temperature of key parts of the reducer such as gears, oil tanks, bearings, etc. and record them, and draw them into a chart. If the temperature continues to rise or suddenly rises, it means there may be problems, such as poor heat dissipation, overload, poor lubrication, etc.

Check operating conditions: Confirm whether the load of the reducer is within the rated range and whether there is overload operation. If the load is too large, the pressure on the reducer will increase, resulting in excessive heat generation. At the same time, check whether the reducer is installed correctly, such as whether the alignment between the reducer and the passive shaft exceeds the allowable range. If the alignment is not good, the output bearing of the reducer will be subjected to excessive radial force, thereby generating a large amount of heat.

Check lubrication status: Check whether the amount of lubricating oil is appropriate. If the oil level is too high or too low, it may cause heat. If the oil level is too high, the oil will lose power and cause a large amount of heat to be generated; if the oil level is too low, the friction between the gears and bearings and other components will increase, which will also generate too much heat. In addition, we should also pay attention to the quality of the lubricant, such as whether the oil quality is worse and whether it is contaminated. Deteriorated or contaminated lubricant will affect its lubricating performance, which will lead to abnormal heating.

Listen to the sound of the equipment: The normally operating reducer should make a smooth mechanical movement sound. If there is abnormal sound or noise, it may indicate that there are problems with the reducer, such as gear wear, bearing damage, etc. These problems may also be accompanied by abnormal heating.

Feel the vibration: Touch the reducer case with your hands to feel the vibration amplitude. Under normal circumstances, the vibration of the reducer should be relatively mild. If the vibration is significantly intensified, it may be caused by failure of internal components, such as gear imbalance, bearing damage, etc., which may also lead to abnormal heating.
