Angular contact ball bearing seal technology for noise prevention play an important role in

  Angular contact ballwheel bearing (Angular Contact Ball Bearings) both radial and axial loads. In high speed work. Larger the contact angle, the higher the axial load capacity. High-precision and high-speed bearings usually take the contact angle of 15 degrees. In the axial force, the contact angle will increase. Single row angular contact ball bearings can withstand axial load in one direction, the radial load, will cause additional axial force. And the only limit shaft or housing in a direction of axial displacement. Angular contact ball bearing contact angle of 40 degrees, so you can bear large axial load. Angular contact ball bearing non-separation type design, inner and outer rings on both sides of the shoulder uneven. In order to improve the bearing load capacity, which would lower side of the shoulder machined, so that the ball bearings can be put more.
Bearing noise is the importance of environmental pollution, but also the bearing industry an important indicator of the need to control, especially for home appliances, office machinery, instrumentation fillet
Ball bearing noise limit is more prominent. Over the past years, China's bearing industry in reducing bearing noise has done a lot of work, so that the bearing noise level has greatly improved, but compared with other countries, there is still a certain gap between users reflect prominent is "different tone" issues , which appears in an irregular bearing operation sudden sound, and even scream. Bearing noise factors are many and complex, requiring the overall design of the bearing, the bearing of each part - the inner ring, outer ring, cage, rolling and lubricants (grease) to analyze the research, but also from the angular contact ball bearings used in each part of the material, add -1-212 Arts process equipment used as well as engineering, process materials and other aspects to analysis. This is bearing noise technology involves the basic content.
