Abstract
The utility model provides a retainer for a bearing. The retainer is characterized by comprising an annular retainer seat, wherein the retainer seat is provided with a plurality of grooves; an annular retainer cover is further arranged at one side, which is located at openings of the grooves, on the retainer seat; the retainer seat is in snap joint connection with the retainer cover; a roller containing cavity is defined by the inner walls of the grooves and the retainer cover. With the adoption of the technical scheme, the retainer for the bearing provided by the utility model can be used for preventing the roller from being separated from the retainer; the retainer can be prevented from being broken and the performance is stable when the bearing is operated at high speed.
Description
Technical field
The utility model relates to field of bearings, particularly a kind of retainer of bearing.
Background technique
Traditional bearing has generally comprised outer ring, inner ring, is arranged on retainer, roller between outer ring and inner ring, and described retainer is provided with the containing groove of placing for roller.But, it is simple in structure for existing retainer, after installation, roller easily with retainer disengaging, and, for the more bearing of roller number, such as flexible bearing, in order to satisfy the demand, the sidewall of containing groove is generally thinner, so in use, the impact force that roller produces is carried by the sidewall of containing groove, thereby containing groove sidewall easily ruptures, in addition, because the retainer structure of roller both sides is asymmetric, weight is not reciprocity, therefore in High Rotation Speed, retainer can produce axial thrust load, cause the inner discontinuity equalization of bearing, affect the high speed performance of bearing.
Summary of the invention
The purpose of this utility model: in order to overcome the defect of prior art, the utility model provides a kind of retainer of bearing, it can prevent that roller and retainer from departing from well, and, can prevent retainer fracture, stable performance in the time of can also making bearing high speed operation.
The technical solution of the utility model: a kind of retainer of bearing, it is characterized in that: the maintenance stand that includes ring-type, described maintenance stand is provided with some grooves, the upper retainer lid that is also provided with ring-type in slot opening one side of described maintenance stand, described maintenance stand is connected with retainer cover latch, between described groove inwall and retainer lid, surrounds roller holding cavity.
Adopt technique scheme, the roller holding cavity of this structure, retainer lid can prevent that roller and retainer from departing from well; Owing to keeping stand to be connected with retainer cover latch, in bearing using process, the impact force that roller produces is by maintenance stand and the carrying of retainer lid of both sides like this; And, the retainer lid arranging can be so that roller both sides balanced weight, realize the dynamic balancing in rotation process, improve the high speed rotating performance of bearing, therefore, the retainer of the bearing of this structure, it can prevent that roller and retainer from departing from well, and, can prevent retainer fracture, stable performance in the time of can also making bearing high speed operation.
Further setting of the present utility model: be equipped with bayonet socket on the maintenance stand between adjacent two grooves, described retainer lid includes some cover board bodies that respective slot position arranges, between described adjacent cover board body, be connected with clamp, described clamp is fastened in bayonet socket and forms and keep stand to be connected with the buckle of retainer lid.
Adopt above-mentioned further setting, by clamp being fastened in bayonet socket, forming and keep stand to be connected with the buckle of retainer lid, buckle is convenient like this, dismounting is also convenient; And, bayonet socket is all set on the retainer between each adjacent rollers, retainer covers corresponding bayonet socket position and is equipped with clamp, makes like this retainer lid and keeps stand buckle tightr, and it is more firm to locate, and while highly rotating, bearing capacity is better.
Further setting more of the present utility model: described clamp is the rounded setting in cross section, and described bayonet socket correspondence is circular-arc setting.
Adopt above-mentioned further setting again, the clamp of this structure, bayonet socket set-up mode, convenient buckle, dismounting, used convenient.

Fig. 2 is retainer stand structure schematic diagram in the utility model specific embodiment;
Fig. 3 is retainer lid structural representation in the utility model specific embodiment.
Embodiment
As Figure 1-3, a kind of retainer of bearing, include the maintenance stand 1 of ring-type, described maintenance stand 1 is provided with some grooves 11, on described maintenance stand 1, be positioned at the retainer lid 2 that groove 11 opening one sides are also provided with ring-type, described maintenance stand 1 covers 2 buckles with retainer and is connected, and between described groove 11 inwalls and retainer lid 2, surrounds roller holding cavity 3.The roller holding cavity 3 of this structure, retainer lid 2 can prevent that roller and retainer from departing from well; Owing to keeping stand 1 to cover 2 buckles with retainer, be connected, in bearing using process, the impact force that roller produces is by maintenance stand and the carrying of retainer lid of both sides like this; And, the retainer lid 2 arranging can be so that roller both sides balanced weight, realize the dynamic balancing in rotation process, improve the high speed rotating performance of bearing, therefore, the retainer of the bearing of this structure, it can prevent that roller and retainer from departing from well, and, can prevent retainer fracture, stable performance in the time of can also making bearing high speed operation.In the utility model specific embodiment, keep stand 1, retainer lid 2 to make by nylon, glass fibre, its pliability is better, and tensile strength, the good mechanical performance such as expansion coefficient, and also its mechanical strength and wear resistance are good.
In the utility model specific embodiment, on the maintenance stand 1 between adjacent two grooves 11, be equipped with bayonet socket 12, described retainer lid 2 includes some cover board bodies 21 that respective slot 11 positions arrange, between described adjacent cover board body 21, be connected with clamp 22, described clamp 22 is fastened on the interior formation of bayonet socket 12 and keeps stand 1 to be connected with the buckle of retainer lid 2, wherein, described clamp 22 is the rounded setting in cross section, and described bayonet socket 12 correspondences are circular-arc setting.By clamp 22 being fastened on to the interior formation of bayonet socket 12, keep stand 1 to be connected with the buckle of retainer lid 2, buckle is convenient like this, dismounting is also convenient; And, on the retainer between each adjacent notches 11, bayonet socket 12 is all set, on retainer lid 2, corresponding bayonet socket position is equipped with clamp 22, makes like this retainer lid 2 and keeps stand 1 buckle tightr, it is more firm to locate, and while highly rotating, bearing capacity is better.
