What are angular contact ball bearings, their characteristics and installation methods?
Angular contact ball bearings can withstand axial force and radial force in one direction at the same time. The line connecting the upper and lower points of the rolling element stress point has a certain angle with the radial direction. This type of bearing is an angular contact bearing.
What kind of bearings do angular contact ball bearings belong to?
1. Angular contact bearings belong to ball bearings in rolling bearings.
2. Since angular contact bearings can withstand radial force and a certain axial force at the same time, their installation methods are mostly in pairs, with back-to-back and face-to-face forms.
3. Angular contact bearings] are available in two types: integral and separable. During installation, a certain axial force is generally given to eliminate bearing clearance. Therefore, bearings generally do not provide clearance.
What is the difference between angular contact ball bearings and aligning ball bearings?
Angular contact ball bearings can bear both radial and axial loads. Can work at higher speeds. The larger the contact angle, the higher the axial load capacity.
Because the raceways of the inner and outer rings can have relative displacement on the horizontal axis, they can bear radial loads and axial loads at the same time - combined loads (single row angular contact ball bearings can only bear axial loads in one direction, so they are generally Installed in pairs).
Since the outer ring raceway surface is spherical, the self-aligning ball bearing has self-aligning performance, so it can automatically adjust the axis misalignment caused by deflection or non-concentricity of the shaft or shell. The tapered bore bearing can be easily installed on the bearing by using fasteners. Steel plate stamping cage on shaft
The inner wheel and steel balls can tilt freely toward the outer wheel. Therefore, a certain degree of assembly error (misalignment) or deflection of the axis can be automatically adjusted without damaging the bearing.
Characteristics and uses of angular contact ball bearings:
Angular contact ball bearings have a high limit speed and can bear both radial and axial loads, as well as pure axial loads. Their axial load capacity is determined by the contact angle and increases with the increase of the contact angle. Single row angular contact ball bearings can only bear axial load in one direction. When bearing radial load, additional axial force will be caused, and corresponding reverse load must be applied. Therefore, this type of bearing is generally used in pairs.
Double row angular contact ball bearings can withstand large combined radial and axial bidirectional loads and moment loads, mainly radial loads. They can limit the bidirectional axial displacement of the shaft or shell, and the contact angle is 30 degrees. Angular contact ball bearings installed in pairs can withstand combined radial and axial bidirectional loads, mainly radial loads, and can also bear pure radial loads.
The tandem configuration can only bear axial loads in one direction, while the other two configurations can bear axial loads in either direction. This type of bearing is generally submitted to the user in pairs selected by the manufacturer. After installation, there is preload interference, and the ferrule and steel ball are in an axial preload state, thus improving the entire set of bearings as a single support stiffness and rotation.
