Abstract
The utility model discloses a roller bearing retainer, belongs to a part on a roller bearing and comprises an upper annular baffle plate and a lower annular baffle plate. The upper annular baffle plate and the lower annular baffle plate are coaxial, a plurality of connecting columns are disposed between the upper annular baffle plate and the lower annular baffle plate and are circumferentially, equidistantly and uniformly distributed, a space among each two adjacent connecting columns, the upper annular baffle plate and the lower annular baffle plate is encircled by a mounting hole used for holding a roller, two or more peripheral bumps used for positioning the rollers are arranged on two peripheral sides of each connecting column, and the distance between each two adjacent peripheral bumps on the corresponding connecting column is smaller than the diameter of the corresponding roller which is placed in the corresponding mounting hole in advance. When the roller bearing retainer is used for assembling the rollers, the rollers can be conveniently placed into the mounting holes from inner sides by assembling workers without being pressed into the mounting holes by the aid of external force, assembly is carried out simply and conveniently, squeezing and abrasion generated when the rollers are assembled are avoided, and accordingly the service lives of the rollers are greatly prolonged.
Description
Technical field:
The utility model relates to a kind of roller bearing, specifically is a kind of roller bearing retainer.
Background technique:
Existing roller bearing retainer generally comprises 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 retainer of wearing and tearing.
The technical solution of the utility model is; A kind of roller bearing retainer with following structure is provided: comprise 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, are with a mounting hole that is used to place roller between adjacent two attachment posts and last annular catch, the following 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 putting into the mounting hole roller in advance.
The described roller bearing retainer 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 retainer has the following advantages: adopt groove to come positioning roller different with existing technology; The utility model roller bearing retainer 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 retainer easily; Need not to be pressed into through external force, assembling is simple, convenient, in addition again; 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.
Description of drawings:
Fig. 1 is the stereochemical structure profile schematic representation of the utility model roller bearing retainer;
Fig. 2 is the stereochemical structure profile schematic representation of the utility model roller bearing retainer when roller is housed.
Embodiment:
Below in conjunction with accompanying drawing and embodiment the utility model roller bearing retainer is done further explain:
As depicted in figs. 1 and 2; In this embodiment; The utility model roller bearing retainer comprises coaxial last annular catch 1 and following annular catch 2; Upward between annular catch 1 and the following annular catch 2 some attachment posts 4 are arranged, some attachment posts 4 equidistantly evenly distribute along circumference, are with a mounting hole 5 that is used to place roller 6 between adjacent two attachment posts 4 and last annular catch 1, the following annular catch 2; All there are two circumferential projection 3 that are used for positioning roller 6 some attachment post 4 circumferential both sides, and the distance on the adjacent attachment post 4 between circumferential protruding 3 is less than the diameter of putting into mounting hole 5 rollers 6 in advance.
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.
