Abstract
The utility model provides a butt fusion formula bearing holder, includes the holder body, is provided with the spacer block at the interval on the holder body, forms ball pocket hole between the adjacent spacer block, and the mouth of closing up has been seted up to ball pocket hole top, the peripheral processing in baffle upper portion has the chamfer, and the spacer block top is connected with the upper cover through the butt fusion mode. Compared with the prior art, the welded type bearing retainer provided by the utility model has the advantages that the upper cover is welded above the retainer, so that the retainer filled with balls is integrated, on one hand, the steel balls are not easy to fall off from the retainer, on the other hand, the integral strength of the retainer is improved, and the service life is prolonged.
Description
Technical Field
The utility model relates to the field of bearing processing, in particular to a welding type bearing retainer.
Background
The bearing generally comprises an outer ring, an inner ring and a steel ball, wherein a retainer is arranged between the outer ring and the inner ring, the steel ball is stored by the retainer in a separated mode, the retainer is made of metal or nonmetal nylon, phenolic tape, polytetrafluoroethylene and the like, the retainer made of nonmetal materials has elasticity, and when the bearing works, noise generated by the steel ball and friction between the steel ball and the retainer are small, so that the non-metal retainer is widely applied to miniature bearings, but after the bearing is used for a long time, the retainer is easy to deform.
SUMMERY OF THE UTILITY MODEL
The present invention is directed to a welded bearing retainer, which overcomes the above-mentioned shortcomings of the prior art.
In order to solve the technical problems, the utility model adopts the technical scheme that:
the utility model provides a butt fusion formula bearing holder, includes the holder body, is provided with the spacer block at the interval on the holder body, forms ball pocket hole between the adjacent spacer block, and the mouth of closing up has been seted up to ball pocket hole top, the peripheral processing in baffle upper portion has the chamfer, and the spacer block top is connected with the upper cover through the butt fusion mode.
Furthermore, the retainer body and the upper cover are both made of nylon materials.
Furthermore, first chamfers are processed on the left side and the right side of the upper portion of the spacer block, and second chamfers are processed on the front side and the rear side of the upper portion of the spacer block.
Furthermore, the opening at the upper end of the retainer body is circular; the upper cover is an annular cover plate, the inner diameter of the upper cover is larger than that of the opening, and the outer diameter of the upper cover is smaller than that of the opening.
Compared with the prior art, the welded type bearing retainer provided by the utility model has the advantages that the upper cover is welded above the retainer, so that the retainer filled with balls is integrated, on one hand, the steel balls are not easy to fall off from the retainer, on the other hand, the integral strength of the retainer is improved, and the service life is prolonged.
Drawings
FIG. 1 is a schematic structural view of the present invention;
FIG. 2 is a schematic structural view of the cage body of the present invention;
the cage comprises a cage body 1, a cage body 2, a spacer block 3, a ball pocket hole 4, a closing-in part 5, an upper cover 6, a first chamfer 7 and a second chamfer.
Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below.
As shown in fig. 1 and 2, a welded bearing retainer, including holder body 1, the interval is provided with spacer 2 on holder body 1, forms ball pocket hole 3 between the adjacent spacer 2, and ball pocket hole 3 is used for storing the steel ball, and closing in portion 4 has been seted up to ball pocket hole 3 top, and closing in portion 4 prevents that the steel ball from running out ball pocket hole 3, 2 peripheral processing in upper portion of baffle have the chamfer, and spacer 2 top is connected with upper cover 5 through the butt fusion mode, and in this embodiment, holder body 1 and upper cover 5 all adopt the nylon material, and butt fusion is on holder body 1 in upper cover 5 bottom after the heating, and each spacer 2 upper portion and upper cover 5 bottom make holder body 1 and upper cover 5 combine into a whole, promote the intensity of holder.
First chamfers 6 are processed on the left side and the right side of the upper portion of the spacer block 2, the first chamfers 6 enable a V-shaped inlet to be formed above the closing-in portion 4, and a steel ball can conveniently enter the ball pocket 3.
The upper end opening of the retainer body 1 is circular, the upper cover 5 welded on the retainer body 1 is an annular cover plate, the inner diameter of the upper cover 5 is larger than the inner diameter of the opening, and the outer diameter of the upper cover 5 is smaller than the outer diameter of the opening, so that the appearance deformation generated by welding the upper cover 5 can not influence the inner ring and the outer ring of the bearing; and second chamfers 7 are processed on the front side and the rear side of the upper part of the spacer block 2, and the upper cover 5 is not easy to fall off by utilizing the welding of the second chamfers 7 and the upper cover 5.
The present invention is not limited to the embodiments described above, and those skilled in the art may make modifications or changes within the scope of the disclosure without departing from the spirit of the present invention, so that the scope of the present invention is defined by the appended claims.
