Abstract
The utility model provides a ball bearing nylon retainer, and belongs to the technical field of bearings. The ball bearing nylon retainer comprises a plurality of continuously arranged pockets, lock claws are arranged at the end parts of the pockets, reinforcing ribs are processed between the lock claws and the end parts of the pockets, and the deflection directions of all the lock claws are the same; the inside fat groove A that is equipped with of pocket hole, the pocket hole terminal surface bottom is equipped with fat groove B. The ball bearing nylon retainer can reduce the rotation resistance, effectively reduce the noise, save the production cost and facilitate the demoulding.
Description
Technical Field
The utility model belongs to the technical field of bearings, and particularly relates to a nylon retainer for a ball bearing.
Background
The locking notch of the ball bearing nylon retainer in the prior art is composed of two locking claws, and the design of the two locking claws causes large rotation resistance, more materials, heavy weight of the retainer and high production cost; in addition, the retainer of the two locking claw locking openings is difficult to demould, and the production efficiency is low.
SUMMERY OF THE UTILITY MODEL
Aiming at the defects in the prior art, the utility model provides the ball bearing nylon retainer, which saves the production cost, reduces the rotation resistance and improves the production efficiency.
The present invention achieves the above-described object by the following technical means.
The utility model provides a ball bearing nylon keeps ware, includes a plurality of pockets that set up in succession, and the locking claw is installed to pocket hole tip, and all locking claws's deflection direction is the same.
In the technical scheme, a reinforcing rib is processed between the locking claw and the end part of the pocket.
In the technical scheme, the pocket is internally provided with the fat storage groove A.
In the technical scheme, the bottom of the end face of the pocket hole is provided with a fat storage groove B.
In the above technical solution, the radius SR of the pocket is 0.515 the diameter of the bearing steel ball.
In the above technical solution, the outer diameter H of the retainer is the center diameter +0.48 × the diameter of the bearing steel ball.
In the above technical solution, the inner diameter h of the retainer is equal to the central diameter-0.48 × the diameter of the bearing steel ball.
The utility model has the beneficial effects that:
(1) according to the ball bearing nylon retainer, the locking claws with the same rotating direction are arranged at the end parts of the continuously arranged pockets, namely, a single-claw locking opening is adopted, so that the material is saved, the weight of the retainer is reduced, and the production cost is reduced; the deflection direction of the locking claw is consistent with the rotation direction of the bearing, so that the rotation resistance can be reduced, and the noise is effectively reduced; in addition, the single-claw locking port retainer is convenient for demoulding and improves the production efficiency.
(2) The grease storage grooves are formed in the inner portion of the pocket hole and the bottom of the end face of the ball bearing nylon retainer, and are used for storing lubricating media, so that the lubricating performance of the retainer is improved, and the service life of the ball bearing is prolonged.
(3) According to the utility model, the locking claw is arranged at the end part of the pocket hole through the reinforcing rib, so that the strength of the locking claw is improved, and the deformation of the locking claw is prevented.

FIG. 2 is a cross-sectional view of a single pawl latch according to the present invention;
in the figure: 1-locking claw, 2-reinforcing rib, 3-grease storage tank A, 4-grease storage tank B.
Detailed Description
The utility model will be further described with reference to the following figures and specific examples, but the scope of the utility model is not limited thereto.
As shown in fig. 1 and 2, the ball bearing nylon retainer of the present invention has the following main dimensions: the outer diameter H of the retainer is equal to the diameter of the steel ball at the center, the inner diameter H of the retainer is equal to the diameter of the steel ball at the center, and the radius SR of the pocket of the retainer is equal to the diameter of the steel ball at 0.515; the central diameter is as follows: after the retainer is provided with the steel balls, the distance between the centers of the two steel balls is opposite.
The ball bearing nylon retainer comprises a plurality of continuously arranged pockets, the end parts of the pockets are provided with locking claws 1, reinforcing ribs 2 are processed between the locking claws 1 and the end parts of the pockets, and the reinforcing ribs 2 can improve the strength of the locking claws 1 and prevent the locking claws 1 from deforming; the deflection directions of all the locking claws 1 are the same and are consistent with the rotation direction of the bearing, so that the rotation resistance is reduced, and the noise is effectively reduced; the inside fat groove A3 that is equipped with of pocket, pocket terminal surface bottom are equipped with fat groove B4, and fat groove A3 and fat groove B4 can store the lubricant, improve and keep ware lubricating property, and then improve ball bearing's life.
When the ball bearing nylon retainer is used, the steel ball of the ball bearing is arranged in the retainer pocket, and the steel ball is tangent to the outer ring channel and the inner ring channel of the ball bearing.
The present invention is not limited to the above-described embodiments, and any obvious improvements, substitutions or modifications can be made by those skilled in the art without departing from the spirit of the present invention.
