Angular contact ball bearing is a more common type of rolling bearing, and the basic angular contact ball bearing is composed of an outer side, an inner hole, a group of bearing steel balls and a group of ball bearings. There are two types of angular contact ball bearings: column and double row. The serial number of angular contact ball bearings is 6, and the serial number of double-row angular contact ball bearings is 4. Its structure is simple and practical, and it is a more common and widely used bearing.
Angular contact ball bearing principle: angular contact ball bearing key to bear axial load, but can also bear axial load and radial load. When it bears only axial load, the interfacial tension is zero. Angular contact ball bearings have the characteristics of angular contact bearings when the axial backlash is large and can bear large radial loads.
Angular contact ball bearing bearing structure: angular contact ball bearing structure is simple, compared with other types, easy to achieve higher manufacturing precision, thus conducive to mass production, manufacturing costs are also low. This type also has various shape modification structures, such as: angular contact ball bearings with sealed caps, angular contact ball bearings with silicone seals, angular contact ball bearings with stop grooves, steel ball grooves with stop grooves, double row angular contact ball bearings.
What is angular contact ball bearing contact Angle
1, angular contact ball bearings can bear radial load and axial load at the same time. Can work at higher rotational speeds.
2, the larger the contact Angle, the higher the axial carrying capacity.
3. The contact Angle is the Angle between the contact point connection of the ball and raceway in the radial plane and the vertical line of the bearing axis. High precision and high speed bearings usually take a 15 degree contact Angle.
4, under the action of axial force, the contact Angle will increase. The inner and outer rings of angular contact ball bearings are provided with raceways, and the inner and outer rings can be relative displacements along the bearing axial direction.
5, this kind of bearing is especially suitable for bearing compound load, that is, radial and axial load simultaneously. The axial load bearing capacity of angular contact ball bearing increases with the increase of contact Angle.
6. The contact Angle is the Angle between the contact point connection of the ball and raceway in the radial plane and the vertical line of the bearing axis.
