Introduction to Different Types of Cardithing Bearings

1.adjust the roller bearing

The centered roller bearing has a double-row roller, the outer ring has a common spherical raceway, the inner ring has 2 raceways and is tilted to an angle relative to the bearing shaft. This clever construction makes it automatically adjustable and therefore not susceptible to the influence of shaft and bearing seat angle on error or shaft bending, and is suitable for installation error or shaft deflection and causing angle error. In addition to being able to withstand radial loads, the bearings can also withstand axial loads for two-way use.

The inner hole of the center-tuned roller bearing has cylindrical and conical two kinds, the conical cone hole cone is 1:30 and 1:12, this conical inner hole bearing is equipped with a tight or discharge sleeve, the cone-shaped inner hole centerball bearing can be easily and quickly assembled on the optical shaft or ladder shaft machine.

2. the tuning ball bearing has cylindrical holes and conical holes two structures, the material of the cage has steel plate, synthetic resin and so on. It is characterized by the outer ring raceway is spherical, with automatic centering, can compensate for different centiance and axis deflection caused by the error, but its internal and outer ring relative tilt should not exceed 3 degrees.

3. adjust the roller bearing

The centered roller bearing is a bearing that assembles a drum roller between the inner ring with two raceways and the outer ring of the dome with the dome, as shown in Figure 3. The centered roller bearing has two columns of rollers, mainly to withstand radial loads, but also to withstand the right amount of axial load in either direction, and has a high radial load capacity, especially suitable for operation under radial heavy loads or vibrational loads, but can not withstand pure axial loads.

4. automatic hearting bearings

Integral bearings, sectioned bearings and auto-centered bearings are widely used in machines in radial sliding bearings.

The ratio of bearing width to diameter is B/d. With the increase of B/d, the bending of the shaft or the tilt of the shaft hole can easily cause local contact between the shaft neck and the end of the shaft tile, resulting in severe wear and fever when B/d 1. 5, it is recommended to use automatic centering bearings. This bearing is characterized by a combination of the sphere of the bearing and the inner surface of the bearing seat and the bearing cover, with the ball center on the shaft of the shaft neck, so that when the shaft is bent, the shaft tile can be automatically adjusted to meet the neutral requirements of the shaft neck.
