河北What are the causes of overheating of winding machine bearings?

Winding machine damage, many reasons are caused by winding machine overheating, therefore, in the operation of winding machine, there are provisions, such as winding machine bearing temperature shall not exceed the allowable value, bearing cover edge can not have oil leakage phenomenon, eliminate these two phenomena, basically there will be no other reasons, so, we focus on the analysis of winding machine bearing heating reasons. There are many reasons for winding machine bearing overheating, the common reasons are:

1. The imbalance of the inner and outer rings of ball bearings is one of the reasons leading to the heating of bearings. The imbalance between the inner ring and the outer ring may be due to machining. Because the winding machine frame and the end cover are processed separately, sometimes the bearing holes on the two end covers are not coaxial (that is, the center line is not in the same straight line). In addition, poor assembly, uneven tightening of end cap screws, dust and dirt on the block may also lead to the imbalance of the inner and outer rings. If the inner and outer rings of the bearing are not balanced, the steel ball and the inner and outer rings will be scraped, thus increasing friction and heat. If there is no other reason, clean the machine port and reassemble it. Tighten the screws one by one in diagonal order. By automatic adjustment step by step, a small amount of errors formed in the process of processing can be improved.

2. Bearing cover and shaft rub against each other. Because the axis of the shaft and the axis of the shaft driven mechanical equipment are not in the same straight line when assembling, or because of inaccurate processing, resulting in the bearing cover inner ring eccentric, so that the bearing cover and the shaft friction. Light is the bearing heating, heavy is smoking, large high-speed motor friction quickly red. At this time should stop immediately, otherwise the winding machine will be burned.

3. Too much or too little lubricating oil is also the cause of fever. If the bearing is used for a long time, the internal lubricating oil will gradually decrease, leading to insufficient lubrication, increased friction loss, and bearing heating. If the bearing lacks oil for a long time, the bearing will be damaged. Too much oil or too thick oil can also cause bearings to overheat. In addition, if the lubricating oil is mixed with hard impurities, the bearing is not cleaned, or the bearing is cleaned with dirty oil, so that there are sand and iron filings in the bearing, it will increase the mechanical friction of the bearing, so that the bearing is heated, and the bearing is easy to damage the impurities.

4. If the belt is too tight or the winding machine is not in the same straight line with the axis of the motor, that is, the bearing load will increase and heat.

Through the analysis of the above reasons, it is hoped that everyone can pay more attention when using the winding machine, the correct use of the winding machine equipment, prevent the winding machine overheating caused by equipment damage, to protect the life and property safety of employees.
