Popular science bearing knowledge
2017-12-06
With the development of science and technology and the progress of society, the development of brass bushes in various industries is also growing rapidly. For example, in the machinery industry, bearings occupy a very important position in this industry. But for non-professionals, Need to know more about expertise, here is JINTAI for you to popularize some bearing knowledge about information.
Currently, there are many types of bearings, angular contact ball bearings, for example, China Bearing Trading Network for everyone to introduce the characteristics of angular contact ball bearings.
1, Angular contact ball bearings can bear both radial bronze bore bearing load and axial load, high speed, contact resin-based ball holding the larger the angle, the higher the axial bearing capacity. 2, single row bearings can only bear one direction of axial load, radial load, will cause additional axial force. And can only limit the axial displacement of the shaft or the housing in one direction.
Relevant person in charge of China Bearing Trading Network introduced: If the angular contact bearings installed in pairs, so that the outer ring of a pair of bearings relative to the wide end face wide end face, narrow end face narrow end face. This avoids additional axial forces and limits the shaft or housing to axial play in both directions.
Second, the nominal contact angle of 15 °, 25 °, 40 ° three, the greater the contact angle the higher the axial load capacity. High-precision and high-speed bearings usually take 15 ° contact angle, under the action of axial force, the contact angle will increase, at present, the angular contact ball bearing variants as many as 70 kinds.
Generally for the inner ring or outer ring with a lock, the inner and outer rings can not be separated. After the outer ring is heated and expanded, it is assembled with the inner ring, the rolling element and the cage assembly. Filled ball than the number of deep groove ball bearings, the rated load in the ball bearing the largest, strong rigidity, stable operation. You can use the inner and outer rings to adjust the radial displacement of each other. Often used in pairs, and the pre-load, in order to improve bearing rigidity.
