Abstract
The said ball bearing includes steel balls and at least one of inner ring, shaft with ball groove and outer ring, and it features its ball-retaining casing or ring, which prevents balls from departing from groove and makes the bearing become one without holder and separable. It has the merits of great number of balls, large load-bearing capacity, good performance and detachability, and it is esp suitable for use in steering gear of automobile and in bicycle.
Description
What the present invention relates to is a kind of antifriction-bearing box, and it is fit to all main frames uses, and particularly is fit to the used angular contact ball bearings of deflector such as automobile.
Existing angular contact ball bearing, its non-divergence type be as 968000 bearings, its band outer cover, no retainer, completely adorns ball, and its weak point is just because of inseparable, thereby can not satisfy the requirement that the online assembling of deflector such as automobile and maintenance are loaded and unloaded.Its divergence type dish type commonly used or C shape retainer, use C shape retainer exactly as 9168306 bearings, its weak point is except making complexity, cause the ball bore deformation when also being to assemble crimp and be difficult to and detect, therefore, 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 to decrease ring, the reliable running of main frame there is potential risk.
Purpose of the present invention is exactly a weak point and a kind of separable and angular contact ball bearing that steel ball can not spin off from raceway groove of retainer that do not have is provided in the above-mentioned technology.
The technical solution that the present invention adopts is: a kind of angular contact ball bearing, one of its minimum axle that comprises inner ring or the steel ball raceway groove is arranged, outer ring and steel ball, it is characterized in that: being provided with on inner ring or outer ring or axle neither influences steel ball work, can prevent the block cover or the circle of blocking that steel ball spins off from its raceway groove again.
The described cover or the circle of blocking of blocking, it is solid on the external diameter of inner ring or outer ring or on the internal diameter or in the groove of termination or on the external diameter of axle, its shape and steel ball coupling have the anti-collision space S, its free end internal diameter or external diameter to the distance L at inner ring or outer ring raceway edge less than sphere diameter d, the distance L of the relative standard width of a room in an old-style house of its free end is less than sphere diameter d, steel ball can freely be rotated, it can not be spun off from its raceway groove.
The present invention makes it both have the advantage that the dress nodule number is many, carrying is big, performance is good owing to adopt on inner ring or outer ring or axle and be provided with the block cover or the circle of blocking, and makes it separable and satisfied the main frame assembling and keeped in repair the requirement of loading and unloading again, makes it enlarge field of application.
