High-precision bearings specifically designed for air conditioning compressors, ensuring smooth rotation, low friction, and long service life under high-speed and high-temperature conditions.
Hub bearing is one of the key components of automobile.
Its main function is to support the weight of the vehicle and ensure the wheels can rotate smoothly.
The following is a detailed introduction:
Structure and Composition Inner ring and outer ring Hub bearings usually have two main parts: inner ring and outer ring.
The inner ring is generally closely matched with the half shaft and connected by spline or interference fit.
For example, in the hub bearings of many front-drive vehicles, the inner ring is connected with the driving axle shaft, and the power is transmitted to the inner ring through the axle shaft.
The outer ring is fixed with the wheel hub, which is directly connected with the wheel and bears various forces from the road surface.
Rolling element Rolling body is the key part of hub bearing to realize low friction rotation.
Common rolling elements are ball and roller.
The ball bearing can bear certain radial and axial loads, and the ball rolls between the inner ring and the outer ring.
The point contact mode makes the ball bearing have less friction when rotating at high speed, which is suitable for light load and high-speed operation.
The roller of roller bearing is cylindrical roller or tapered roller, and the roller is in line contact with the inner and outer rings.
It can bear large radial load and certain axial load, and is often used for heavy-duty vehicles.
Cage The main function of the cage is to evenly separate the rollers and avoid them from colliding and rubbing with each other during operation.
Cages are generally made of metal or plastic.
The metal cage has high strength and is suitable for high load and high temperature environment.
Plastic cage has the advantages of light weight and low friction coefficient, which can reduce the noise of bearing operation.
Compatible with rotary, scroll, and reciprocating compressor types.
