The higher the speed, the larger the contact angle, Angular Contact Ball Bearing the higher the axial bearing capacity. Single row bearing can only bear axial load in one direction, which will cause additional axial force when bearing radial load. And can only limit the axial displacement of the shaft or housing in one direction.
make the outer rings of a pair of bearings opposite, that is, the wide end face to the wide end face, and the narrow end face to the narrow end face Angular Contact Ball Bearing. In this way, additional axial force can be avoided, and the shaft or housing can be limited to the axial clearance in both directions. There are more than 70 variant structures of angular contact ball bearings.
are 15 °, 25 ° and 40 °. The larger the contact angle is, the higher the axial bearing capacity is. High precision and high-speed bearings usually take 15 ° contact angle, which will increase under the action of axial force.
is provided with a locking port, and the inner and outer rings cannot be separated. The outer ring is assembled with the inner ring, rolling element and cage assembly after heating and expansion. The number of Angular Contact Ball Bearing balls installed is more than that of deep groove ball bearing. The rated load is large in the ball bearing, with strong rigidity and stable operation.
can be adjusted by the mutual displacement of the inner and outer rings. It is often used in pairs and preloaded to improve the rigidity of the Angular Contact Ball bearing.
Because the rolling body in the thrust tapered roller bearing is a tapered roller, structurally, the rolling bus and the raceway bus of the washer meet at a point on the axis line of the bearing, so the rolling surface can form pure rolling, and the limit speed is higher than that of the thrust cylindrical roller bearing. The thrust tapered roller bearing can bear unidirectional axial load. The type code of thrust tapered roller bearing is 90000.
most of the models produced by various factories are non-standard overall dimensions, while there are few varieties of series with standard overall dimensions. Therefore, at present, there is no Angular Contact Ball Bearing national standard for the overall dimensions of this kind of bearings.
The contact angle of thrust angular contact ball bearing is generally 60 °. The commonly used thrust angular contact ball bearing is generally a two-way thrust angular contact ball bearing, which is mainly used for the spindle of precision machine tools. It is generally used together with double row cylindrical roller bearing, and can bear two-way axial load. It has the advantages of high precision, good rigidity, low temperature rise, high speed, convenient assembly Angular Contact Ball Bearing and disassembly, etc.
There are many structures of double row tapered roller bearings, a large number of which are 35000 type. There is a double raceway outer ring and two inner rings. There is a spacer between the two inner rings. The clearance can be adjusted by changing the thickness of the spacer. This kind of bearing can bear both radial load and bidirectional axial load, and can limit the axial displacement of shaft and housing within the range of axial clearance of bearing.
The type code of tapered roller bearing is 30000, and the tapered roller bearing is a separate bearing. In general, especially in GB / T307 The outer ring and inner assembly of tapered roller bearing within the size range involved in 1-94 tolerances for radial bearings of rolling bearings can be used interchangeably. The angle of the outer ring and the diameter of the outer raceway are the same as the overall dimensions and are standardized. It is not allowed to change during design and manufacturing.
can be interchanged all over the world. Tapered roller bearings are mainly used to bear the combined radial and axial load dominated by radial load. Compared with angular contact ball bearing, the bearing capacity is large and the limit speed is low. Tapered roller bearing can bear axial load in one direction and limit axial displacement of shaft or shell in one direction.
