FAQ

1. Quality Failure Case - Consequences of Incorrect Motor Shoulder Dimensions
      Main Dimension Chains of Motor Products
   For motor products, bearings are the key components that support the mechanical movement of the motor. Whether it is the radial fit size or the axial size relationship, it plays a vital role in the normal operation of the motor.
   
   In the radial direction, the bearing ensures that the radial clearance of the bearing does not appear abnormal through direct or indirect cooperation with the shaft, the bearing chamber, the end cap lip, and the seat lip; The relationship between the length of the bearing chamber of the cover and the height of the inner and outer cover of the bearing ensures that the axial clearance of the bearing is normal when the motor is running.
   
   On the premise that other dimensions meet the requirements, we analyze the most common problems of non-conformance of the shoulder dimensions of the ball bearing structure. If the shoulder size is too large or too small, the axial relative position of the bearing and the associated components will deviate, and in severe cases, the bearing cannot enter the bearing chamber. For the motor that has been inspected and passed the factory, it means that the error range of the shoulder size is relatively close to the allowable size of the motor's axial dimension chain.
   
   For most motor bearings, one end is the fixed end, that is, it is limited by the inner and outer covers of the bearing, leaving no axial gap, while the other end is the floating end, leaving a gap of about 0.5mm in the axial length of the bearing chamber, that is After normal assembly, the nominal distance between the end face of the bearing outer ring and the end face of the bearing inner cover and outer cover is 0.5mm to ensure the axial thermal expansion and contraction of the rotor part when the motor is running or the ambient temperature changes. changing needs.
   
   When the size of the shaft shoulder is larger than the normal size, the outer ring of the bearing is in a relatively static state due to the limiting effect of the outer cover of the bearing, while the inner ring of the bearing will undergo axial displacement due to the elongation of the shaft. The position of the rolling elements deviates, and the abnormal friction with the cage causes the bearing heating problem.
   
   On the contrary, when the size of the shaft shoulder is smaller than the normal size, the outer ring of the bearing is subjected to an outward axial force due to the limiting effect of the inner cover of the bearing, and the final result is the deviation of the relative position of the rolling elements and the abnormal friction with the cage. .
   
   From the above analysis, we can see that if the size of the motor shaft shoulder does not meet the requirements, it will inevitably lead to the abnormal operation of the bearing, and the motor will cause serious faults such as holding the shaft or even burning due to the heating of the bearing.
   
   From the perspective of quality inspection and control, the shaft shoulder size should be regarded as a key quality control point during the machining process of the shaft. For the repair of the faulty motor, in most cases, it is solved by adjusting the height of the bearing cover, and if necessary, adjust the length of the bearing chamber of the end cover. However, for the repaired motor, the parts involved are non-standard parts, and there is no good interchangeability.
