FAQ

1. The relationship between "bearing clearance" and motor performance
   Bearing clearance Also known as bearing clearance. The so-called bearing clearance refers to the amount of movement when the bearing is not installed on the shaft or bearing housing, one of the inner ring or the outer ring is fixed, and then the side with the bearing clearance that is not fixed is moved radially or axially. .
   
   Influence of bearing working clearance
   
   Bearing clearance is an important parameter in the use of motor bearings. If the working clearance is too small, it will cause heat generation or even high temperature locking. If the working clearance is too large, it will cause vibration and reduce the service life of the bearing.
   
   High temperature of motor bearing and bearing noise are common problems encountered by motor manufacturers. In addition to the factors of the bearing itself, the processing quality, assembly process, and matching relationship of other parts and components related to the motor and bearings will affect the final product to varying degrees. Assembly effect.
   
   
   Adjust and correct bearing working clearance
   
   The clearance-free operation of the bearing is an ideal state that the assembly process strives to achieve. Some motor manufacturers will use the actual matching method for large-size motors to achieve the purpose of adjusting the working clearance of the bearing, but considering the tolerance zone of the specially equipped parts Factors, the cost of achieving a good state of bearing clearance through actual matching is relatively high;
   
   If an axially acting spring element is used to adjust the bearing, backlash-free operation can also be achieved. The spring element is generally placed between the bearing cover and the outer ring of the axially movable bearing.
   
   Under the working conditions of the motor, the electric bearing can withstand a certain bidirectional axial force in addition to the radial load.
   
   The bearings at both ends of the small motor use ball bearings, and the problem of swimming must be considered; the medium motor uses cylindrical roller bearings at the load end and ball bearings at the non-load end. Deep groove ball bearings are generally used as locating end bearings and do not have the ability to move axially. Cylindrical roller bearings are mostly used at the load end, bear large radial loads, and have the characteristics of axial swimming.
