Sino&Germany (Z&D) sharing: the structural characteristics of the 6 -type angle contact of the ball bearings

Release Time : 2022/01/17 Read：

Dual -column -angle contact ball bearings can withstand large radial loads, axial -oriented loads and torque loads, which are mainly radial loads. It can limit the two -way axial displacement of the shaft or shell, and the contact angle is 30o.

The limit speed of the bearing of the corner contact is high, which can withstand the radial load and axial load at the same time. It can also withstand the axial direction load. ) Decisions and increased with the contact angle.

This type of bearing is suitable for double support shafts with low support spacing and rigidity.

The main structural forms of angle contact ball bearings are: single -column angle contact ball bearings, dual -column angle contact ball bearings, and pair -paired corner contact ball bearings, four -point contact ball bearings.

There are two types: separate and non -separated type of ball bearing. The basic type of the separation angle contact is S70000. The SN70000 type is a separate type, and its inner and outer ring can be installed separately, suitable for the limited parts of the installation conditions. The inner ring and outer ring of non -separated angle contact cannot be installed separately. The contact angles are 15O, 25O, and 40O. The limit speed of the lock mouth in the inner ring bearing is higher than the limit speed of the lock mouth in the upper bearing of the outer ring.

Single -rowed angle contact ball bearings can only withstand axial loads in one direction. When withdrawing the radial load, the additional axial force will be caused. The corresponding reverse axial load must be applied. Therefore, this bearing is generally used in pairs.

The pair -paired corner contact ball bearings are composed of two sets of single -row angle of the same specifications of the same specifications. The ball bearings are composed of different groups. According to the combination of the outer ring end surface, it can be divided into: series configuration (70000/dt), back -to -back configuration (70000) /Db) and face -to -face configuration (70000/df).

This type of bearing can withstand radial and axial loads mainly based on radial loads, and can also withstand pure radial loads. The series configuration can only withstand the axial load in one direction. The other two configurations can withstand the axial load in any direction. This type of bearing is generally submitted to the user after the production manufacturer is selected and combined. After the installation, there is a pre -pressure hyperbench. Rotate and rotation accuracy.

Four points of contact with the ball bearings are separated bearing. Among them, the QJ0000 (17600) has a double inner circle, the QJF00 port type (116000) has a double half -outer ring, the contact angle is 35O, and when the load -free and pure radial load effect, the steel ball and the sleeve circle are four o'clock in four o'clock. touch. Under the action of pure axis load, steel balls and sleeves are in two contacts, which can withstand two -way axial load. This type of bearing can also withstand the power load of the power, and has the functions of single -column and dual -column angles. This type of bearing can ensure normal work only when two points of contact.
