The utility model has the advantages that the running resistance is small, the energy and the effort are saved, the impact caused by low-temperature environments and lubricating oil shortage is small, the lubricating effect is good, the assembling and the disassembling are facilitated, the limit number of revolution of the bearing in the same model can be improved by more than one time, the service life is long and the like.
Description
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.
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.
The model utility content:
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, a plurality of balls are respectively cylindrical roller, and its two ends have the taper platform respectively, both ends of the surface center at ball convexes with axle bed respectively, is set with the ball axostylus axostyle on axle bed 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, a plurality of locking tooths are replaced in annular groove, back-up ring upper end have with the taper platform be complementary domatic, the back-up ring rear end is connected with a plurality of locking tooths.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, and inner ring is installed in the inboard of a plurality of balls, and the taper platform of a plurality of ball one end mates mutually with inner ring retaining angle respectively.
The utility model will be noted the direction of installing in use, and the face of awl mouthful and the face that has back-up ring 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 locking tooth 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, and integral part can be reduced to the resistance of sliding friction minimum, and running resistance is little, energy and labour saving.Retainer is difficult for abrasion deformation, and the influence that lacked by low temperature environment and lubricant oil is less, high lubricating effect.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, and the limit revolution of same model bearing can be enhanced about more than once, long service life.
