Importance of Bearing System in Electric Motors and the Need for Careful Bearing Selection

The bearing system is a critical and important control element for electric motor products, and the performance requirements for bearings vary depending on the different motors and operating conditions.

Some operating conditions require motors to have higher load capacity, some require electric motors to have axial load, and some environmental conditions require motors to be free from noise.

Therefore, careful consideration should be given to the matching of bearings for electric motors.

Considerations for Bearing Fit and Axial Movement in Electric Motors

Regarding the fit between bearings and associated components, on the one hand, it is necessary to control the radial fit relationship of the bearings, and on the other hand, it is also necessary to consider the necessity of axial direction movement.

As for the shielded bearings themselves, when there is no axial force acting, or its axial force does not affect the axial clearance of the bearing life, the radial fit relationship should be considered.

From the analysis of the axial force of the electric motor bearings, for locating ball bearing, since their axial displacement has been limited by associated components, only the radial fit relationship needs to be considered.

Radial and axial play are critical factors in the design and performance of electric motors

However, for the floating-end bearings of the electric motor, it is necessary to adjust the fit relationship between the cylindrical roller bearings and the associated components according to the selected type of bearings.

Bearing Fit Considerations for Rotating Rotor in Electric Motors

According to the special nature of rotor rotation in electric motor operation, the inner ring of both locating-end and floating-end bearings should be fitted with an interference fit with the shaft to prevent circumferential relative motion between the inner ring and the shaft during rotation, which is commonly known as inner or outer ring spinning.

Electric motor bearings typically consist of both inner and outer rings, which are designed to support the rotating shaft and maintain its position within the motor assembly

The fit between the outer bearing ring and the bearing housing should be distinguished according to the type of bearing.

The load carrying capacity of an electric motor is an important consideration in selecting the appropriate motor for a particular application

When a separable bearing is used for the floating end, a small clearance fit between the outer ring of the bearing and the bearing housing can be used, and the clearance selection should ensure that the working clearance of the bearing during operation meets the requirements.

When a non-separable bearing is used for the floating end, there should be sufficient clearance between the outer ring of the bearing and the section of the bearing inner and outer cover stop grooves to allow for axial sliding of the bearing due to thermal expansion and contraction.

It is particularly important to emphasize that the surface roughness and roundness of the bearing housing are crucial to ensuring that the outer ring of the bearing is not damaged due to excessive external forces.

Comprehensive Evaluation of ball Bearings Clearance Control and Importance of Communication with Bearing Suppliers

The control of radial clearance of bearings is related to both the fit relationship between the inner ring of the ball bearings and the shaft, and the fit relationship between the outer ring of the bearing and the bearing housing.

Different manufacturers have different tendencies in choosing tolerances, and the effectiveness of processing parts may also vary.

Therefore, when choosing bearing clearance, a comprehensive evaluation should be conducted based on the characteristics of the specific application, and communication with the bearing supplier is particularly important.

Bearing clearance refers to the gap between the rolling elements of the deep groove ball bearings and the inner and outer ring shells of the bearing.

The amount of movement when the unfixed side of the bearing ring clearance is radially or axially moved is referred to as the bearing clearance.

According to the direction of movement, it can be divided into radial loads clearance and axial clearance.

The size of the operating clearance during operation affects the rolling fatigue life, temperature rise, noise, vibration, and other performance characteristics of the bearing.
