Cylindrical roller bearing retainer

Technical Field

The utility model relates to the technical field of bearings, in particular to a cylindrical roller bearing retainer.

Background

The prior art is usually applied to the bearing in the precision lathe main shaft mostly to the cylindrical roller bearing, and the cage that the cylindrical roller bearing adopted in the prior art has the flange, and the flange can be nearly all with filling groove usually, when the operating personnel loads the roller, push into the cage pocket through the filling groove can, but to the cylindrical roller bearing of small-size, its filling groove is difficult to design, if the too dark easy channel of beating of design still can appear sharp-pointed protruding, leads to the roller to be scratched, still is difficult to process simultaneously, if the filling groove is too shallow can be difficult to assemble.

Disclosure of Invention

Aiming at the defects of the prior art, the utility model provides a cylindrical roller bearing retainer, which aims at solving the problem that a filling groove of the cylindrical roller bearing retainer is difficult to process in the prior art.

In order to achieve the above purpose, the utility model provides a cylindrical roller bearing retainer, which comprises a left frame body, wherein a plurality of beam bodies are circumferentially distributed on the inner peripheral wall of the left frame body, pocket holes for accommodating external rollers are formed between each beam body and each adjacent beam body, the two side wall surfaces of each beam body are arc surfaces for contacting with the surfaces of the external rollers, tangential surfaces for enabling external operators to rapidly install the rollers into the pocket holes are recessed on each arc surface, each tangential surface is arranged close to the opening of each adjacent pocket hole, the radial cross sections of the tangential surfaces are in arc shapes, and the distance between two tangential surfaces in the pocket holes is larger than the distance between the two arc surfaces.

The technical scheme is beneficial in that: the operating personnel put into the pocket hole through the tangent plane with external roller, because of the interval between two relative tangent planes in every pocket hole needs to be greater than the interval between two relative arcwall faces, and the roller contacts with the arcwall face again, make the roller can be through the smooth pocket hole that enters into of tangent plane, and the radial cross-section of tangent plane is circular-arc setting, the roller of laminating more, make operating personnel can quick assembly disassembly roller advance the holder, and then improve bearing packaging efficiency, the tangent plane is offered for the sunken arc face simultaneously, both convenient processing, also can not produce sharp point and come the fish tail roller simultaneously, ensure the normal operating of roller.

The utility model further provides that: the novel beam comprises a right frame body, slots are formed in the outer wall of the beam body along the respective length direction, inserting blocks are arranged on the right frame body corresponding to the positions of the slots, and each inserting block is arranged in an expansion fit with the corresponding slot.

The technical scheme is beneficial in that: the right frame body is in expansion fit with the inserting grooves to realize stacking combination with the left frame body, further sealing of the pocket is realized, and the roller is placed to be separated from the pocket to cause failure of bearing operation.

The utility model further provides that: each insert block is sleeved with an anti-falling sleeve, and the anti-falling sleeves are made of rubber materials.

The technical scheme is beneficial in that: the setting of anticreep cover ensures that the inserted block can not break away from the slot easily among the above-mentioned technique, and the anticreep cover is made by the rubber material simultaneously, and then has improved the friction moment between anticreep cover and the slot inner peripheral wall, has increased the joint strength between inserted block and the slot, has phase change has improved the joint strength between left support body and the right support body.

The utility model further provides that: and a filling plate for filling the tangential plane is extended on the inner peripheral wall of the right frame body corresponding to each tangential plane, and the radial section of each filling plate is arranged in an arc shape.

The technical scheme is beneficial in that: the block of filling board and tangent plane makes the arcwall face more whole, and the arcwall face can be with the better contact of external roller under the condition that coincides with the tangent plane promptly, and then ensures that the roller rotational speed can not receive the influence, can also prevent simultaneously that the roller from upwards breaking away from the pocket through the tangent plane when filling board and tangent plane coincide, and then avoid the roller to break away from the raceway and lead to the bearing to become invalid, fills the tangent plane through the filling board simultaneously and can also prevent to rock under the high-speed operation of bearing in the pocket and lead to the bearing running rate to receive the influence.

The utility model further provides that: the right frame body is hollow and is provided with a fat storage cavity, each filling plate is provided with an oil outlet communicated with the fat storage cavity on the upper end face, and the outer peripheral wall of the right frame body is provided with an oil filling hole communicated with the fat storage cavity.

The technical scheme is beneficial in that: the solid grease is stored in the grease storage cavity, the temperature of the bearing is gradually increased when the bearing runs at a high speed, so that the solid grease is converted into liquid grease, at the moment, the liquid grease can flow onto the surface of the filling plate through the oil outlet, and then the grease can flow into the pocket to coat the roller.
