Abstract

A radial rolling bearing comprises an inner ring, an outer ring, a plurality of balls, a retainer, check rings and elastic check rings, wherein each ball is a columnar roller with cone bosses at the two ends thereof, and ball shaft levers are fixedly arranged on shaft seats of each ball respectively; inner ring horns are arranged on the outer wall of one end of the inner ring, and ring-shaped grooves are formed on the outer wall of the other end thereof; the check rings are sleeved on the ring-shaped grooves while the elastic check rings are clamped in the ring-shaped grooves; outer ring horns matched with the cone bosses at the end parts of each ball are arranged on the inner wall of one end of the outer ring, and conical openings inclined outwards are formed on the other end of the outer ring; and the retainer comprises two ring-shaped catches and a plurality of supporting pieces, wherein ball shaft level sockets, oil storage grooves and oil penetration holes are formed on the retainer respectively, and the balls are mounted between the two ring-shaped catches respectively. The utility model has the advantages of large loading amount, energy and labor conservation, little possibility of abrasion and deformation of the retainer, little influence of a low-temperature environment and the deficiency of lubricating oil, good stability, convenient assembly and disassembly, long service life, etc.

Description

Radial antifriction bearing

(1) technical field:

The utility model relates to a kind of bearing, particularly relates to a kind of improvement to the rolling bearing structure that has retainer.

(2) background technique:

The present rolling bearing of usefulness, ball majority be spheroidal and cylindrical and by the retainer location, and its deficiency is when bearing rotates, and retainer contacts generation with ball resistance is big, consumes energy greatly, and is easy to wear, working life weak point.

(3) summary of the invention:

The technical problems to be solved in the utility model provides a kind of rolling friction that makes full use of, and reduces sliding friction, adopt the location, the center of circle of ball, the resistance of sliding friction is reduced to minimum, it is little to consume energy, retainer is difficult for abrasion deformation, the radial antifriction bearing that can increase the service life.

Radial antifriction bearing, comprise inner ring, outer ring, a plurality of ball, retainer, back-up ring and circlip, a plurality of balls are respectively cylindrical roller, and its two ends have the taper platform respectively, convex with axle respectively in the both ends of the surface center of ball and sit, take at axle and be set with the ball axostylus axostyle respectively.With a plurality of ball end tapered platforms matching part inner ring retaining angle is arranged on the outer wall of inner ring one end, on the other end outer wall of inner ring, annular groove is arranged, and be set with back-up ring, circlip is fastened in the annular groove, back-up ring upper end have with the taper platform be complementary domatic, the back-up ring rear end is replaced on circlip.The retaining angle, outer ring that is complementary with ball end tapered platform is arranged on the inwall of outer ring one end, and the outer ring the other end has outward-dipping awl mouth, is convenient to the bearing loading and unloading.Retainer is made of two annular catch and a plurality of supporting element, and two annular catch be arranged in parallel, and a plurality of supporting element is fixedly installed between two annular catch by desired location respectively.Inboard two annular catch correspondences, and between per two supporting elements, be respectively equipped with ball axostylus axostyle socket, on the annular catch between two ball axostylus axostyle sockets, be provided with oil storage tank, and oil seepage hole leads in the ball axostylus axostyle socket on both sides, make the contact position of retainer and a plurality of balls, can keep good lubricated the long term.A plurality of balls are installed in respectively between two annular catch, and the ball axostylus axostyle at two ends is plugged in respectively in the ball axostylus axostyle socket, the outer ring is set on the exterior edge face of a plurality of balls, inner ring is installed in the inboard of a plurality of balls, and the inner ring retaining angle that the taper platform of a plurality of ball one end is complementary with it respectively closely cooperates.

The utility model will be noted the direction of installing in use, and the face of awl mouthful and the face that has circlip be in the same side, and two bearings when installing and using on axle want symmetry to install, and on-stream like this back-up ring and circlip are basic just not to have born external force.

The utility model has the advantages that: a plurality of balls adopt cylindrical roller, and location, the center of circle has reduced the sliding-frictional resistance between retainer and a plurality of ball.The ratio comparatively dense that a plurality of balls are arranged, load quantity is big, energy and labour saving, retainer is difficult for abrasion deformation, and the influence that lacked by low temperature environment and lubricant oil is less.Under the state that separates in the outer ring, inner ring, ball, retainer etc. can mutual restriction, become one closely, and good stability is convenient to installation and removal, long service life.
