A self-aligning bearing is a specially designed bearing with the following structure and function:
Structure:
1. Inner and outer rings: Self aligning bearings usually consist of inner rings, outer rings, rolling elements, and retainers. The inner and outer rings are the main body of the bearing, with the inner ring installed on the shaft and the outer ring installed on the housing or seat.
2. Rolling element: Rolling elements are usually spherical or cylindrical, rolling between the inner and outer rings, transmitting loads and bearing forces.
3. Cage: Cage is used to maintain the positioning and spacing of rolling elements, usually made of metal or plastic.
Function:
1. Automatic centering ability: The self-aligning bearing has the ability to automatically adjust the position of the rolling element to ensure the normal operation of the bearing when the bearing load is uneven or there is a deviation between the shaft and the bearing seat.
2. Can withstand large deflection angles: Self aligning bearings can withstand large deflection angles, making them suitable for situations with harsh working conditions or frequent adjustments, such as excavators, cranes, etc.
3. Bearing radial and axial loads: Self aligning bearings can withstand both radial and axial loads simultaneously, with high load-bearing capacity.
4. Reduce vibration and noise: Due to the good automatic centering ability of self-aligning bearings, vibration and noise caused by deviations can be reduced, and the stability and smoothness of equipment operation can be improved.
In general, self-aligning bearings have the characteristics of automatic centering ability, bearing large deflection angles, and bearing radial and axial loads. They are suitable for working conditions with uneven loads or frequent adjustments, and can ensure the normal operation and long-term stability of equipment.
