Abstract
The utility model discloses a track and needle roller bearing. The key points of the technical scheme are as follows: an inner ring has a penetrating through hole, an end surface at one end of the inner ring is connected with an end surface at one end of an outer ring in a propping-against way, a hollow part is formed by the inner ring and the outer ring through connection, rolling needles are placed in the hollow part between the inner ring and the outer ring, a retainer ring is arranged on the end surface of the outer ring, which is opposite to the end surface where the outer ring and the inner ring are in propping-against connection, an elastic piece is arranged between the retainer ring and the propping-against connection part of the inner ring and the outer ring, and the retainer ring and the inner ring are at the same level. The track and needle roller bearing has small possibility of sliding and high stability precision.
Description
Technical field
The utility model relates to a kind of mechanical transmission, and more particularly, it relates to a kind of bearing.
Background technique
Bearing is to work the parts of fixing and reducing the load friction factor in mechanical transmission course.Also can say, when other parts produce relative movement each other on axle, be used for reducing the fixing parts of friction factor and retainer shaft central position in power transmission process.Bearing is a kind of very important component in contemporary machinery.Its major function is the supported mechanical solid of rotation, the mechanical load friction factor in order to reduction equipment in transmission process.Bearing easily occurs that in the process of installing contact is unstable or slides now, and easily skew to a certain degree occurs.
The model utility content
The deficiency existed for prior art, the purpose of this utility model is to provide a kind of not being prone to slide and the high bearing of stable precision.
For achieving the above object, the utility model provides following technological scheme: a kind of outer ring and roll assembly, comprise needle roller, inner ring and outer ring, described inner ring is placed in outer ring, described inner ring is provided with the through hole run through, described inner ring one end end face is conflicted and is connected with outer ring one end end face, be connected to form hollow part between inner ring and outer ring, described needle roller is placed between the hollow part between inner ring and outer ring, described outer ring connects relative place, other end conflict with the inner ring conflict and is provided with back-up ring, described back-up ring and inner ring and conflict joint, outer ring are provided with elastic component, described back-up ring flushes with inner ring.
By adopting technique scheme, by being provided with the through hole that runs through inner ring, can make when bearing fixedly the time, among inserting bearing, the axle part makes, the air of the inside can be pushed away from the through hole of inner ring, can well make between axle and bearing fully fixing, and inner ring contacts end face and outer ring with outer ring and back-up ring conflict end is provided with elastic component by arranging, can finely by this elastic component, make the axle part be not easy skew, add in outer ring and conflict and be connected with back-up ring, by coordinating of back-up ring and elastic component, further make the axle part can be good at avoiding occurring that placement location is inaccurate, improved the precision of bearing.
The utility model further is set to: described elastic component is jump ring.
By adopting technique scheme, elastic component is set to jump ring, can well play a part to stop on axle or the motion of the part axial on hole.
The utility model further is set to: described jump ring removably connects and is placed in conflict end face inside and outside and outer ring and outer ring and back-up ring.
By adopting technique scheme, inside and outside being removably connected, jump ring with outer ring and outer ring and back-up ring, is convenient to dismounting and the assembling of bearing, be convenient to maintenance.
The accompanying drawing explanation
The schematic diagram that Fig. 1 is the utility model embodiment outer ring and roll assembly.
Reference character in figure: 1, needle roller; 2, inner ring; 3, back-up ring; 4, jump ring; 5, outer ring.
Embodiment
With reference to Fig. 1, the utility model embodiment is described further.
A kind of outer ring and roll assembly, comprise needle roller 1, inner ring 2 and outer ring 5, described inner ring 2 is placed in outer ring 5, described inner ring 2 is provided with the through hole run through, described inner ring 2 one end end faces are conflicted and are connected with outer ring 5 one end end faces, be connected to form hollow part between inner ring 2 and outer ring 5, described needle roller 1 is placed between the hollow part between inner ring 2 and outer ring 5, described outer ring 5 connects relative place, other end conflict with inner ring 2 conflicts and is provided with back-up ring, described back-up ring 3 and inner ring 2 are provided with elastic component with 5 conflict joints, outer ring, and described back-up ring flushes with inner ring 2.
By adopting technique scheme, by being provided with the through hole that runs through inner ring 2, can make when bearing fixedly the time, among inserting bearing, the axle part makes, the air of the inside can be pushed away from the through hole of inner ring 2, can well make between axle and bearing fully fixing, and inner ring 2 contacts end face with outer ring 5 and outer ring 5 is provided with elastic component with back-up ring 3 conflict ends by arranging, can finely by this elastic component, make the axle part be not easy skew, add that 5 conflicts are connected with back-up ring 3 in outer ring, by coordinating of back-up ring 3 and elastic component, further make the axle part can be good at avoiding occurring that placement location is inaccurate, improved the precision of bearing.
The utility model further is set to: described elastic component is jump ring 4.
By adopting technique scheme, elastic component is set to jump ring 4, can well play a part to stop on axle or the motion of the part axial on hole.
The utility model further is set to: described jump ring 4 removably connects and is placed in conflict end inside and outside and outer ring 5 and outer ring 5 and back-up ring 3.
By adopting technique scheme, inside and outside being removably connected, jump ring 4 with outer ring 5 and outer ring 5 and back-up ring 3, is convenient to dismounting and the assembling of bearing, be convenient to maintenance.
Because the utility model example solves the outer ring and roll assembly not high problem of precision that easily occurs sliding, improved its precision and stability and be difficult for sliding capability.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, those skilled in the art carries out common variation and replaces should being included in protection domain of the present utility model in the technical solutions of the utility model scope.
