Abstract
The invention provides a novel rolling bearing which comprises an inner ring, an outer ring, a plurality of balls, a retainer and a retainer ring. The plurality of balls are cylindrical rollers, two ends of one cylindrical roller are respectively provided with conical tables, and ball axles are respectively fixed on axle seats; an inner ring retaining horn is arranged on an outer wall at one end of the inner ring, an annular groove is arranged on an outer wall at the other end of the inner ring and is sleeved with the retainer ring, and a plurality of retaining teeth abut in the annular groove; an outer ring retaining horn matching with the conical table at the end of the ball is arranged on an inner wall at one end of the outer ring, and a conical opening outwardly inclined is arranged at the other end of the outer ring; the retainer composed of two annular retaining plates and a plurality of support members is respectively provided with faucets for the ball axles, an oil storage tank and oil permeating holes, and the plurality of the balls are respectively arranged between the two annular retaining plates. The novel rolling bearing provided by the invention has the advantages of small running resistance, conservation of energy and labor, small possibility of being influenced by a low temperature environment and shortage of lubricating oil, a good lubrication effect, convenient installation and dismounting, capacity of improving extreme revolution by more than one time compared with the extreme revolution of a bearing of a same type, a long service life, etc.
Description
Technical field:
The present invention relates to a kind of bearing, particularly relate to a kind of having the rolling bearing of 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.
Summary of the invention:
The technical problem that the present invention will solve provides a kind of rolling friction that makes full use of, and reduces sliding friction; Adopt the location, the center of circle of ball, be reduced to the resistance of sliding friction minimum, it is little to consume energy; Retainer is difficult for abrasion deformation, a kind of new-type rolling bearing that can increase the service life.
A kind of new-type rolling 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, on axle bed, is 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; 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 up of two annular catch and a plurality of supporting element, and two annular catch laterally arrange, and a plurality of supporting element is fixedly installed between two annular catch by desired location respectively.Two inboards that annular catch is corresponding; 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, makes 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 interior barium J of a plurality of balls, and the taper platform of a plurality of ball one end matees with inner ring retaining angle respectively each other.
The present invention will note 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 have not basically just born external force.
Advantage of the present invention is: 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.
