The roller bearing comprises rollers, an elastic positioning bush, an upper ring-shaped separation blade and a lower ring-shaped separation blade, wherein the elastic positioning bush is used for limiting the radial inward emersion of the rollers, and the upper ring-shaped separation blade and the lower ring-shaped separation blade are coaxially arranged; a plurality of connecting columns are arranged between the upper ring-shaped separation blade and the lower ring-shaped separation blade, and the plurality of connecting columns are circumferentially and uniformly distributed at equal intervals; and two adjacent connecting columns, the upper ring-shaped separation blade and the lower ring-shaped separation blade define an installing hole for placing the rollers; the upper and lower ends of the elastic positioning bush are respectively provided with a plurality of mutually-staggered axial grooves which are circumferentially and uniformly distributed at equal intervals, the elastic positioning bush is arranged in an inner cavity defined by a plurality of rollers, the upper end of the elastic positioning bush is provided with a lug which can be lapped on the upper ring-shaped separation blade, the plurality of connecting columns are all elongated columns, and the distance between two adjacent elongated connecting columns is less than the diameter of each roller. The roller bearing disclosed by the utility model is simple and easy to process, and can effectively avoid the damage and abrasion on the rollers caused by extrusion in the process of assembling.

Description

A kind of 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.Because the requirement on machining accuracy of groove is higher, therefore, above-mentioned roller bearing is processed and is wasted time and energy; In addition; When packing into roller in the 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 crowded the wound and wearing and tearing to roller inevitably, this will directly influence the working life of roller.

The model utility content:

The technical problem that the utility model will solve is to provide a kind of processing simply, conveniently, the roller bearing that in the time of can effectively avoiding assembling roller is produced crowded wound and weares and teares.

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 several rollers surround; The elastic locating sleeve upper end is provided with the lug that can ride on the annular catch; Wherein, some attachment posts are all elongated, and the distance between the adjacent long strip attachment post is less than the diameter of roller.

The described a kind of 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 a kind of 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.

After adopting above structure, compared with prior art, a kind of roller bearing of the utility model has the following advantages:

1, because some attachment posts in a kind of roller bearing of the utility model all are conventional simple long strip structure, therefore, a kind of roller bearing of the utility model is processed simple, convenient;

2, the assembler can put into mounting hole with roller from the inboard of a kind of roller bearing of the utility model easily; Need not to adopt external force to be pressed into again; Assemble more 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 prolonged working life of roller significantly.

Embodiment:

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

Like Fig. 1, Fig. 2 and shown in Figure 3; In this embodiment; A kind of roller bearing of the utility model 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 8 down; Go up annular catch 3 and between the annular catch 8 some attachment posts 7 are arranged down, some attachment posts 7 equidistantly evenly distribute along circumference, and some attachment posts 7 are all elongated; Distance between the adjacent long strip attachment post 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 7 and last annular catch 3, the following annular catch 8, 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 several rollers 5 are surrounded, and the diameter of elastic locating sleeve 1 equals the inscribed circle diameter 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 9 last times of axle at a kind of roller bearing of the utility model and can is ejected and do not participate in work by axle 9; 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.
