Description

A kind of bearing
Technical field
The present invention relates to a kind of bearing, specifically be a kind of resistance less, be suitable for bearing at axial and radial load.
Background technique
Bearing is a kind of component that are used for confirming running shaft and other part relative movement positions, a supporting or leading role, is the parts that carry gravity, transferring power.
The deficiency of existing bearing is: on the resistance that quite a few of power produces in the time of can being lost in bearing operation; This resistance mainly comes from the friction between interior roller of bearing and the retainer; Bearing is big more, and the resistance that its retainer produces is just big more, and then the power of loss is just big more.In addition, the axial load ability of existing bearing is less, has limited its application.
Summary of the invention
The technical problem that the present invention will solve provide a kind of simple in structure, resistance is less, be suitable for the bearing at axial and radial load.
In order to solve the problems of the technologies described above; The invention provides a kind of bearing, comprising: secondary inner ring, be distributed in roller on the secondary inner ring, be located at roller between the adjacent a pair of roller, be set in annular bridge hoop on each roller, tightly be enclosed within the secondary outer ring on this bridge hoop and tightly be placed in the outer ring on this pair outer ring; Said roller axial distribution, each roller are provided with the circular groove that the cross section is a circular arc, and said roller is between the circular groove of adjacent roller; The inner ring of said bridge hoop is provided with and is suitable for and the movable curve bath that cooperates of said roller; Said secondary inner ring comprises a pair of of axial symmetrical distribution, and the outer side edge of secondary inner ring has the flanging that extends radially outwardly, and the exterior edge face of roller is in the inboard of this flanging; Said secondary outer ring comprises and axially is symmetrically distributed in the said outer ring a pair of of week, this inner ring to secondary outer ring constitute one be used for fixing said bridge hoop big circular groove.
Particularly, the joint of the end face of the body of said secondary inner ring and the inner side surface of said flanging had oil groove, and this crosses oil groove integral body ringwise, was used to carry more lubricant oil, to reduce resistance.
Further, have first gap between the inner side end of described a pair of secondary inner ring, be used to carry lubricant oil, to reduce resistance.
Further, have second gap between the inner side end of described a pair of secondary outer ring and be used to carry lubricant oil, to reduce resistance.
During practical implementation; The internal diameter size of the quantity of said roller, the diameter of roller and bridge hoop is suitable for being fitted to each other; So that said roller activity is engaged between the circular groove of curve bath and adjacent roller of bridge hoop inner ring, and the diameter that makes roller is greater than the spacing of said adjacent a pair of circular groove; Cooperating of roller and the curve bath of bridge hoop inner ring, the circular groove on the roller, limited the moving position of roller, and reduced movable resistance.
As a kind of scheme of global optimization, in same radian position, respectively be provided with a roller on the described a pair of secondary inner ring, to symmetrical distribution, said circular groove is located at the inner end of contiguous each roller to roller axle for this; Said roller is between the circular groove with the adjacent roller of circle distribution; Said bridge hoop inner ring be suitable for and the movable curve bath that cooperates of said roller comprise with said circular groove be oppositely arranged a pair of.
As the scheme of further optimization, the end face of the body of said secondary inner ring is centroclinal inclined-plane,, radial load ability axial with further raising.
During practical implementation, said roller is truncated cone, and the tip portion of the roller of this truncated cone is said inner end; Said roller integral body is located on the body of single secondary inner ring.The roller of truncated cone is suitable for axial force is decomposed radially, therefore has better axial load ability, and roller can not produce displacement; The roller clearance that the bearing of this structure adopts is less, is suitable for adopting a fairly large number of roller, is beneficial to the radial load ability that increases.
Further, axially the tip portion of adjacent roller has the gap, and to rub between the tip portion that prevents adjacent roller, this gap is suitable for carrying lubricant oil simultaneously, to increase the lubricant oil space.
As the scheme of further optimization, the outer side edge of said secondary outer ring has second flanging that extends radially inwardly, and the exterior edge face of roller is in the inboard of this second flanging, preventing roller axle to displacement, and improves the radial load ability.
Be to improve the bulk strength of bearing, the inboard drive fit of said secondary inner ring has inner ring, and said secondary inner ring comprises and axially is symmetrically distributed in a pair of of said inner ring periphery.
The assembly method of above-mentioned bearing comprises successively:
Said bridge hoop is located in the said outer ring, then said a pair of secondary outer ring is symmetricly set between outer ring and the bridge hoop;
Said roller and roller are located at successively the inner ring of said bridge hoop;
Said a pair of secondary inner ring is symmetricly set on each roller inboard;
Said inner ring is a tight fit in the inner ring of described a pair of secondary inner ring.
Technique scheme of the present invention is compared existing technology and is had the following advantages: (1) bearing of the present invention, removed the flower basket type retainer that traditional bearing adopts, the power loss of having avoided retainer to cause.Adopt the combination of bridge hoop, roller and roller to realize relatively rotating of Internal and external cycle, because the stress surface between bridge hoop, roller and the roller is an arc-shaped surface, so resistance is less; Cooperating of roller and the curve bath of bridge hoop inner ring, the circular groove on the roller, limited the moving position of roller, said secondary inner ring and secondary outer ring are played the axial limiting effect respectively, and roller can not produce displacement; Therefore, bearing of the present invention has axial preferably and radial load ability.(2) roller that adopts in the twin columns bridge-type bearing of the present invention is truncated cone, and the tip portion of truncated cone roller is oppositely arranged, and the roller of truncated cone is suitable for axial force is decomposed radially, therefore has better axial load ability, and roller can not produce displacement; The roller clearance that the bearing of this structure adopts is less, is suitable for adopting a fairly large number of roller, is beneficial to the radial load ability that increases.(3) bearing of the present invention is applicable to any kind bearing, and for example automobile, wind-driven generator etc. with respect to traditional bearing, can reduce resistance more than 50%; On large size bearing, use, effect is remarkable, is beneficial to energy-conservation.(4) bearing assembly method of the present invention, step is simple, assembling is easy, and product quality ensures easily.
