Fault Analysis and Troubleshooting Methods for Motor Bearings

It is generated by the vibration and impact between the retainer and the rolling elements, and can occur regardless of the type of grease used. It is more likely to occur when subjected to high torque, heavy loads, or large radial clearance.

Methods for repairing paper machine bearings

Bearings are wear-prone components in paper machines. Once they wear out and become ineffective, it is necessary to halt production for replacement, which can result in significant economic losses for the paper mill. Therefore, ensuring the reliable operation of bearings is of great importance for the smooth and continuous functioning of paper machines. This article analyzes methods for online bearing repair.

Basic Knowledge of Rolling Bearings

Rolling bearings are precision mechanical components that convert sliding friction between a rotating shaft and its bearing housing into rolling friction, thereby reducing frictional losses.

The impact of bearing installation on the bearing

Whether the bearing is installed correctly directly affects its precision, service life, and performance during operation. The design and installation sections related to bearing installation must be thoroughly studied and carried out in accordance with operational standards, including verification of the bearing model.

The maximum temperature of the bearing

The surface temperature refers to the temperature of the bearing’s outer surface when the bearing is operating under specified service conditions. At this point, the bearing temperature should not exceed the temperature of the conveyed medium by more than 20℃, and the maximum temperature must not exceed 80℃. For externally mounted bearings, the surface temperature should not exceed the ambient temperature by more than 40℃, and the maximum temperature must not exceed 80℃.

SNF Deep Groove Ball Bearing Model Specifications and Parameters

Deep-groove ball bearings (GB/T 276-1994) are the most widely used type of rolling bearing in the original list of radial ball bearings. They are characterized by low frictional resistance and high rotational speeds. These bearings can be used in components subjected to radial loads or combined radial and axial loads. They are also suitable for components under axial loads, such as small-power motors, automotive and tractor gearboxes, machine tool gearboxes, general-purpose machinery, and tools.
