Abstract
The utility model provides a kind of bearing, comprise inner ring, outer ring and a plurality of support rollers being arranged between described inner ring and described outer ring, described bearing also comprises two symmetrically arranged supplemental support assemblies in the two ends in described support rollers: described supplemental support assembly comprises auxiliary inner ring and auxiliary outer ring, between described auxiliary inner ring and described auxiliary outer ring with the equal corresponding auxiliary rolling element structure that arranges of support rollers described in each, described auxiliary rolling element structure comprises five rolling elements that become star arrangement, between adjacent described auxiliary rolling element structure, a supplemental support roller is all set, described supplemental support roller becomes star arrangement with four adjacent rolling elements, one end of described supplemental support roller is stretched between corresponding adjacent supports roller described support rollers is supported.By the utility model, can further reduce the frictional force of support rollers, improve bearing performance, extend the working life of bearing.
Description
Technical field
The utility model relates to mechanical field, in particular to a kind of bearing.
Background technique
In current cylindrical roller bearing, although support rollers can be rolled, supporting frame is fixing, and frictional force is still larger, and the rotational speed of roller bearing is limited, excess Temperature during rotation, and in the time of performance deficiency, the life-span of bearing itself is also subject to certain impact.
Therefore, need a kind of new bearing, can further reduce the frictional force of support rollers, improve bearing performance, extend the working life of bearing.
Model utility content
Technical problem to be solved in the utility model is, a kind of new bearing is provided, and can further reduce the frictional force of support rollers, improves bearing performance, extends the working life of bearing.
In view of this, the utility model provides a kind of bearing, comprise inner ring, outer ring and a plurality of support rollers being arranged between described inner ring and described outer ring, described bearing also comprises two symmetrically arranged supplemental support assemblies in the two ends in described support rollers: described supplemental support assembly comprises auxiliary inner ring and auxiliary outer ring, between described auxiliary inner ring and described auxiliary outer ring with the equal corresponding auxiliary rolling element structure that arranges of support rollers described in each, described auxiliary rolling element structure comprises five rolling elements that become star arrangement, between adjacent described auxiliary rolling element structure, a supplemental support roller is all set, described supplemental support roller becomes star arrangement with four adjacent rolling elements, one end of described supplemental support roller is stretched between corresponding adjacent supports roller described support rollers is supported.
In this bearing, rolling element and support rollers are synchronized, rotating Vortex, supplemental support roller and support rollers are synchronized, counterrotating (sense of rotation), and rollers all when bearing rotary are by identical linear velocity running, and bearing inside is rolling friction substantially.
In this technological scheme, between supplemental support roller and support rollers, it is rolling friction, avoided the sliding friction between support rollers and supporting frame in existing bearing, reduced the frictional force of bearing inside, the rotational speed of the supplemental support assembly that is can be faster, can increase fatigue life, heating reduces, and inside temperature during use reduces, and extends the working life of bearing, and the parts of the supplemental support assembly parts that more convenient replacing damages when damage, reduced maintenance cost.
Accompanying drawing explanation
Fig. 1 is according to the structural representation of model utility embodiment's bearing;
Fig. 2 is the perspective view of supplemental support assembly in Fig. 1;
Fig. 3 is the plan view of supplemental support assembly in Fig. 1;
Fig. 4 is the local enlarged diagram of supplemental support assembly in Fig. 3.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.It should be noted that, in the situation that not conflicting, the application's embodiment and the feature in embodiment can combine mutually.
As shown in Figures 1 to 4, according to embodiment's of the present utility model bearing, comprise inner ring 1, outer ring 2 and a plurality of support rollers 3 being arranged between described inner ring 1 and described outer ring 2, described bearing also comprises two symmetrically arranged supplemental support assemblies 8 in the two ends in described support rollers 3: described supplemental support assembly 8 comprises auxiliary inner ring 4 and auxiliary outer ring 5, between described auxiliary inner ring 4 and described auxiliary outer ring 5, with support rollers described in each 3 is all corresponding an auxiliary rolling element structure 6 is set, described auxiliary rolling element structure 6 comprises five rolling elements 61 that become star arrangement, between adjacent described auxiliary rolling element structure 6, a supplemental support roller 7 is all set, described supplemental support roller 7 and adjacent 6 one-tenth star arrangement of four rolling elements, one end of described supplemental support roller 7 is stretched between corresponding adjacent supports roller 3 described support rollers 3 is supported.
Particularly, 2-4 by reference to the accompanying drawings, in Fig. 2, can see the outside outstanding one end of supplemental support roller 7, Fig. 3 with in Fig. 4, can see each auxiliary rolling element structure 6 in five rolling elements 61 that become star arrangement and supplemental support roller 7 and adjacent 6 one-tenth star arrangement of four rolling elements (in Fig. 4, auxiliary rolling element structure 6 use heavy lines represent).
In this bearing, rolling element 6 is synchronized with support rollers 3, rotating Vortex, supplemental support roller 7 is synchronized with support rollers 3, counterrotating (sense of rotation), and rollers all when bearing rotary are by identical linear velocity running, and bearing inside is rolling friction substantially.
In this technological scheme, between supplemental support roller 7 and support rollers 6, it is rolling friction, avoided the sliding friction between support rollers 6 and supporting frame in existing bearing, reduced the frictional force of bearing inside, the rotational speed of the supplemental support assembly 8 that is can be faster, can increase fatigue life, heating reduces, and inside temperature during use reduces, and extends the working life of bearing, and the parts of supplemental support assembly 8 parts that more convenient replacing damages when damage, reduced maintenance cost.
In sum, content of the present utility model is not limited in the above-described embodiment, and those skilled in the art can propose other embodiment within technological guidance's thought of the present utility model, but within this embodiment is included in scope of the present utility model.
