Correct Use and Faults of Rolling Bearings
Rolling bearngs are widely used in machinery and production equipment due to its low friction coefficient, good sealing performance, low noise, easy maintenance and high reliability. Therefore, correct use and maintenance of rolling bearings is also very important.
First of all, before using a rolling bearing, the user needs to check its running clearance. The clearance of the bearing is an important condition for its normal work. If the clearance is too large, it will easily cause vibration, which affects the life of the bearing. If the clearance is too small, the bearing will be prone to heating and cannot operate normally.
Secondly, even if the bearing is properly assembled, but there is no lubrication, it will cause premature failure of the bearing. Therefore, after inspection, the rolling bearing should be filled with grease and often inspected. The grease should be added in time in accordance with the regulations of the bearing product. At the same time, attention should be paid to the choice of lubricant, and lubricants of different viscosity should not be mixed.
Thirdly, during the operation of the rolling bearing, it should pay attention to the temperature rise of the bearing. When the bearing runs, its internal friction produces heat. Therefore, the temperature of the bearing will rise accordingly. When the bearing temperature rises, it will not only reduce the bearing life, but also easily cause the bearing to deform or even burn. Therefore, during the operation of the rolling bearing, attention should be paid to the temperature rise of the bearing and appropriate measures should be taken to ensure the normal operation of the bearing.
In addition, misalignment may also cause bearings to fail prematurely. To ensure the normal operation of the rolling bearing, it is necessary to ensure the accuracy of the installation position and perpendicularity, otherwise it will easily cause misalignment, reduce the service life of the bearing and cause vibration or noise.
Lastly, when the rolling bearing is found to be abnormal or loses its original accuracy, it must be replaced in time. When replacing the bearing, the rolling bearing needs to be checked and it is not allowed to use inferior bearing products with poor quality.
In conclusion, the correct use of rolling bearings is very important. Rolling bearings need to be inspected and disassembled properly, wear parts need to be timely replaced, and time should be spent to choose the corresponding lubricants for timely lubrication, inspection and maintenance of rolling bearings is necessary, so as to ensure the safe and normal operation of rolling bearings. In addition, attention should be paid to the misalignment of bearings and the temperature rise of bearings, and timely treatment measures should be taken to ensure the normal operation and life of rolling bearings.
