According to the roller bearing disclosed by the utility model, the rollers can be effectively prevented from being squeezed and abraded when assembling is performed.

Description

Roller bearing

Technical field:

The utility model relates to a kind of bearing, specifically is a kind of roller bearing.

Background technique:

Existing roller bearing generally comprises roller and coaxial last annular catch and following annular catch; Go up annular catch and between the annular catch some attachment posts are arranged down; Some attachment posts equidistantly evenly distribute along circumference; Be with a mounting hole that is used to place roller between adjacent two attachment posts and last annular catch, the following annular catch, be provided with the groove that is used for the setting-in roller on the attachment post of the circumferential both sides of mounting hole.When packing into roller in the above-mentioned mounting hole, need be pressed in the groove on the attachment post with external force, assembling is effort, and in being pressed into the process of roller, can produce to squeeze to roller inevitably and hinder and wearing and tearing, and this will directly influence the working life of roller.

The model utility content:

The technical problem that the utility model will solve is, provide a kind of roller produced to squeeze can effectively avoid assembling the time hinder and the roller bearing of wearing and tearing.

The technical solution of the utility model is; A kind of roller bearing with following structure is provided: comprise roller, be used to limit elastic locating sleeve that roller radially inwardly deviates from and coaxial last annular catch and annular catch down; Go up annular catch and between the annular catch some attachment posts are arranged down; Some attachment posts equidistantly evenly distribute along circumference; Be with a mounting hole that is used to place roller between adjacent two attachment posts and last annular catch, the following annular catch, the elastic locating sleeve upper/lower terminal all has a plurality of mutual dislocation and along the equidistant equally distributed axial groove of circumference, elastic locating sleeve is arranged in the inner chamber that some rollers surround; The elastic locating sleeve upper end is provided with the lug that can ride on the annular catch; Wherein, all there are two or more circumferential projection that is used for positioning roller the some circumferential both sides of attachment post, and the distance on the adjacent attachment post between the circumferential convexity is less than the diameter of roller.

The described roller bearing of the utility model, wherein, the axial depth of axial groove can equal 1/2～3/4 of elastic locating sleeve axial length.

The described roller bearing of the utility model, wherein, the axial depth of axial groove can equal 1/2,2/3 or 3/4 of elastic locating sleeve axial length.

The described roller bearing of the utility model, wherein, the quantity that some circumferential both sides of attachment post are used for the circumferential projection of positioning roller can be two, three, four, five or six.

After adopting above structure, compared with prior art, the utility model roller bearing has the following advantages: adopt groove to come positioning roller different with existing technology; The utility model roller bearing is provided with the circumferential projection that is used for positioning roller in the circumferential both sides of attachment post, therefore, and during the assembling roller; The assembler can put into mounting hole with its inboard from the utility model roller bearing easily; Need not to adopt external force to be pressed into again, assembling is simple, convenient, in addition; Extruding and wearing and tearing that the saving of external force and groove produced when effectively having avoided the roller assembling, thus working life of roller prolonged significantly.

Embodiment:

Below in conjunction with accompanying drawing and embodiment the utility model roller axle is made further explain:

Like Fig. 1, Fig. 2 and shown in Figure 3; In this embodiment; The utility model roller bearing comprises roller 5, be used to limit elastic locating sleeve 1 that roller 5 radially inwardly deviates from and coaxial last annular catch 3 and annular catch 9 down; Go up annular catch 3 and between the annular catch 9 some attachment posts 8 are arranged down, some attachment posts 8 equidistantly evenly distribute along circumference, and all there are two circumferential projection 7 that are used for positioning roller 5 some attachment post 8 circumferential both sides; Distance on the adjacent attachment post 8 between circumferential protruding 7 is less than the diameter of roller 5; Be with a mounting hole 6 that is used to place roller 5 between adjacent two attachment posts 8 and last annular catch 3, the following annular catch 9, elastic locating sleeve 1 top and bottom all have a plurality of mutual dislocation and along the equidistant equally distributed axial groove 4 of circumference, the axial groove 4 of elastic locating sleeve 1 upper end has two; These two axial grooves 4 are 180 ° of symmetrical distributions on circumference; The axial groove 4 of elastic locating sleeve 1 lower end also has two, and these two axial grooves 4 also are 180 ° of symmetrical distributions on circumference, and the axial groove 4 of elastic locating sleeve 1 upper end is 90 ° with the axial groove 4 of elastic locating sleeve 1 lower end along circumference angle each other; The axial depth of axial groove 4 equals 2/3 of elastic locating sleeve 1 axial length; Elastic locating sleeve 1 is arranged in the inner chamber that some rollers 5 are surrounded, and the diameter of elastic locating sleeve 1 equals the inscribe diameter of a circle that several rollers 5 are surrounded, and elastic locating sleeve 1 upper end is provided with the lug 2 that can ride on the annular catch 3.As shown in Figure 4; Elastic locating sleeve 1 is loaded on 10 last times of axle at the utility model roller bearing and can is ejected and do not participate in work by axle 10; In other words, 1 of elastic locating sleeve positions plurality of rollers 5 before dispatching from the factory, and prevents it and in transportation process, in mounting hole 6, radially inwardly deviates from.

Above-described embodiment describes the preferred implementation of the utility model; Be not that scope to the utility model limits; Under the prerequisite that does not break away from the utility model design spirit; Various distortion and improvement that those of ordinary skills make the technological scheme of the utility model all should fall in the definite protection domain of the utility model claims.
