The working principle of self-aligning bearings is based on their special structural design, mainly including the following aspects:
1. Rolling element rolling: Rolling elements (usually spheres) are placed between the inner and outer rings of self-aligning bearings, which can roll between the inner and outer rings and withstand loads from axial and radial directions.
2. Automatic centering ability: When the shaft is subjected to uneven loads or there is a deviation between the shaft and the seat, the rolling element automatically adjusts its position to maintain the relative position and angle between the inner and outer rings. This automatic centering ability enables the bearing to adapt to different working conditions and environments, ensuring the normal operation of the bearing.
3. Can withstand large deflection angles: The design of self-aligning bearings allows them to withstand large deflection angles, usually up to a few degrees or even more. This makes self-aligning bearings suitable for applications that require frequent angle adjustment during operation or are subject to significant vibrations and impacts.
4. Bearing radial and axial loads: Self aligning bearings can withstand both radial and axial loads simultaneously, with high load-bearing capacity and stability.
In summary, self-aligning bearings achieve effective load-bearing and stable operation under different working conditions by rolling between the inner and outer rings with rolling elements, automatic self-aligning ability, and the ability to withstand large deflection angles.
