Abstract
The utility model relates to a high-speed angular contact ceramic ball bearing, which belongs to the field of bearing manufacturing, and includes an outer ring, an inner ring, a cage and a rolling body, wherein the rolling body is arranged between the outer ring and the inner ring through the cage. The rolling body adopts the material component of Cr14Mo4, the outer ring and the inner ring are made of bearing steel, and the cage is made of stainless steel bearing steel wire material and adopts the component of Cr4M4V. The rolling body of the bearing is made of ceramic material with small density, thereby effectively reducing the centrifugal force produced during high-speed rotation, prolonging the service life of the bearing, and improving the limit rotation speed.
Description
Technical field
The utility model relates to a kind of high speed angle contacting ceramic ball bearing, belongs to bearing and makes the field.
Background technique
Angular contact ball bearing can bear radial load and axial load simultaneously, can under high rotational speed, work.The inner ring of present angular contact ball bearing, outer ring, rolling element and retainer adopt the Bearing Steel manufacturing more.Yet bearing is in the process of high speed rotating, because action of centrifugal force often produces contact stress to lasso, and contact stress is the main cause that bearing fatigue damages.For this reason, we provide a kind of highi degree of accuracy angle contacting ceramic ball bearing, and the rolling element of this bearing adopts the little stupalith of density to process, and can effectively reduce the centrifugal force that in the high speed rotating process, produces, and prolongs the bearing physical life, improves limit speed.
Summary of the invention
Defective in view of the prior art existence; The purpose of the utility model provides a kind of high speed angle contacting ceramic ball bearing; The rolling element of this bearing adopts the little stupalith of density to process; Can effectively reduce the centrifugal force that in the high speed rotating process, produces, prolong the bearing physical life, improve limit speed.
The utility model solves the technological scheme that its technical problem adopted: a kind of high speed angle contacting ceramic ball bearing, comprise outer ring, inner ring, retainer, rolling element, and rolling element is arranged between outer ring and the inner ring through retainer.The material composition that described rolling element is selected for use is Cr14Mo4, and described outer ring and inner ring adopt Bearing Steel to process, and described retainer adopts stainless steel bearing steel wire material, and composition is Cr4M4V.
The beneficial effect of the utility model is: a kind of high speed angle contacting ceramic ball bearing, comprise outer ring, inner ring, retainer, rolling element, and rolling element is arranged between outer ring and the inner ring through retainer.The material composition that described rolling element is selected for use is Cr14Mo4, and described outer ring and inner ring adopt Bearing Steel to process, and described retainer adopts stainless steel bearing steel wire material, and composition is Cr4M4V.The rolling element of this bearing adopts the little stupalith of density to process, and can effectively reduce the centrifugal force that in the high speed rotating process, produces, and prolongs the bearing physical life, improves limit speed.
