Description
The present invention relates to a kind of antifriction-bearing box, it is fit to the angular contact ball bearing that all steering boxs such as main frames use, particularly suitable automobile are used.
Existing angular contact ball bearing, its divergence type dish type commonly used or C shape retainer, as 9168306 is exactly with C shape retainer, its weak point also is to cause the ball bore deformation and can't detect when the assembling crimp, therefore except making complexity, in use normal because ball and the bad contact of ball hole, cause the ball hole to be worn and torn too early, even cause its fracture and cause bearing failure, the reliable running of main frame is had potential hidden danger.Its non-divergence type is as 968000 bearings, the band outer cover, do not have retainer, fills ball, and its weak point is just because of inseparable, thereby can not satisfy the requirement of online assembling of steering box such as automobile or maintenance loading and unloading.
Purpose of the present invention is exactly that weak point provides a kind of ball to contact good retainer with the ball hole in the above-mentioned technology in order to avoid, or assembling does not need the retainer of crimp or is not with outer cover, the separable angular contact ball bearing of no retainer.
Technical solution of the present invention is: a kind of angular contact ball bearing, it comprises outer ring, inner ring, steel ball and retainer, it is characterized in that retainer is entity taper sheath or C shape cover, the dress ball hole of retainer is according to the bearing contact angle corresponding angle that tilted, with a fore shaft method or a retaining mouthful method steel ball is placed the ball hole, it can not be dropped out from the hole.
A kind of angular contact ball bearing, it comprises outer ring, inner ring, steel ball and taper or C shape retainer, its feature is being provided with the frame of blocking at least in the hole of described retainer one end.
A kind of angular contact ball bearing, it comprises outer ring, inner ring, reaches steel ball, it is characterized in that being provided with the cover of blocking that prevents that steel ball from dropping out from its raceway on the internal diameter of the two rib outer rings of zanjon one end or on the external diameter of two rib inner ring one ends of zanjon.
Owing to adopted retainer entity or that the frame of blocking is arranged, therefore, can make the ball hole easy to manufacture, assembling does not need crimp and has guaranteed that bearing in running condition ball and ball hole keep well contacting, and makes the bearing revolution flexibly, helps the reliability of bearing and the raising in life-span.On interior cover or outer ring, be provided with the cover of blocking, make it both keep the advantage that the dress ball is many, carrying is big, make it separable and satisfied the requirement that the online assembling of main frame and current maintenance are loaded and unloaded again.
