Abstract
The utility model relates to a deep groove ball holder with store up fat structure, including deep groove ball holder body, set up the ball pocket of placing the steel ball on the deep groove ball holder body, have the linkage segment between the two adjacent ball pockets, set up the arc wall that upwards arches on the bottom face of linkage segment, each arc wall is along deep groove ball holder body evenly distributed, the arc wall top center has been seted up and has been stored up fat groove. The deep groove ball retainer with the grease storage structure has the advantages that through the special arc-shaped groove and the grease storage groove structure, the weight of the retainer can be reduced, the integral strength of the retainer is not affected, after grease is injected into the bearing, certain grease can be stored in the grease storage groove, the bearing can fully lubricate the inner ring raceway, the outer ring raceway and the steel ball of the bearing during high-speed operation, the service life of the bearing is prolonged, and the temperature rise is reduced.
Description
Technical Field
The utility model relates to a bearing technical field especially relates to a deep groove ball holder with store up fat structure.
Background
In the existing deep groove ball retainer, poor lubrication often occurs among a steel ball, a bearing inner ring and a bearing outer ring raceway in the high-speed operation process, so that the noise is overlarge in the operation process, and the bearing operation temperature is increased to cause the bearing failure. Although some bearing retainers begin to adopt an oil storage tank mechanism, for example, a bearing retainer with an oil storage tank on the inner and outer diameters disclosed in patent No. CN201547135U, the structure of the bearing retainer is complicated, the structure of the oil storage tank needs to be formed by post secondary processing, the processing technology is complicated, and the bearing retainer is very inconvenient.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a weight is lighter, lubricated effectual, processing is convenient, can improve the deep groove ball holder that has a fat storage structure of bearing life-span.
The utility model discloses a realize through following technical scheme: the utility model provides a deep groove ball holder with store up fat structure, includes deep groove ball holder body, sets up the ball pocket of placing the steel ball on the deep groove ball holder body, has the linkage segment between two adjacent ball pockets, set up the arc wall that upwards arches on the bottom face of linkage segment, each arc wall is along deep groove ball holder body evenly distributed, store up the fat groove at arc wall top center.
In order to avoid affecting the overall strength of the cage, the depth of the arc-shaped groove is preferably smaller than the depth of the ball pocket, and the width of the arc-shaped groove is smaller than the width of the ball pocket.
Preferably, the grease storage tank is a rectangular or circular grease storage tank, but other similar-shaped tanks can be adopted instead.
Likewise, in order to avoid affecting the overall strength of the cage, the depth of the grease storage groove is less than one third of the thickness of the connecting section.
The utility model has the advantages that: the deep groove ball retainer with the grease storage structure has the advantages that through the special arc-shaped groove and the grease storage groove structure, the weight of the retainer can be reduced, the integral strength of the retainer is not affected, after grease is injected into the bearing, certain grease can be stored in the grease storage groove, the bearing can fully lubricate the inner ring raceway, the outer ring raceway and the steel ball of the bearing during high-speed operation, the service life of the bearing is prolonged, and the temperature rise is reduced.
Drawings
Fig. 1 is a schematic perspective view of a deep groove ball retainer with a grease storage structure according to the present invention;
fig. 2 is a bottom view of the deep groove ball retainer with a grease storage structure of the present invention;
in the figure: 1. the deep groove ball retainer comprises a deep groove ball retainer body, 2 ball pockets, 3 connecting sections, 4 arc-shaped grooves and 5 grease storage grooves.
Detailed Description
The following detailed description of the preferred embodiments of the present invention will be provided in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, and the protection scope of the present invention can be clearly and clearly defined. In the present invention, directional terms such as "up", "down", "front", "back", "left", "right", "top", "bottom", etc. refer to directions of the attached drawings only. Accordingly, the directional terms used are used for describing and understanding the present invention, and are not used for limiting the present invention.
As shown in fig. 1 and 2, a deep groove ball retainer with a grease storage structure comprises a deep groove ball retainer body 1, ball pockets 2 for placing steel balls are uniformly arranged at the top end of the deep groove ball retainer body 1, two adjacent ball pockets are connected through a connecting section 3, an arc-shaped groove 4 which is arched upwards is arranged on the bottom end face of the connecting section 3, each arc-shaped groove 4 is uniformly distributed along the deep groove ball retainer body 1, the depth of each arc-shaped groove 4 is smaller than that of each ball pocket 2, the width of each arc-shaped groove is approximately the same as that of the connecting section 3, a rectangular grease storage groove 5 is arranged at the center of the top end of each arc-shaped groove 4, the grease storage groove 5 extends upwards and does not penetrate through the connecting section 3, and the depth of each arc-shaped groove is smaller.
Tests prove that the overall weight of the deep groove ball retainer with the grease storage structure is about two thirds of the weight of the original deep groove ball retainer, but the overall strength of the deep groove ball retainer is basically the same as that of the original deep groove ball retainer, the grease storage groove 5 and the arc-shaped groove 4 can be formed with the body in one step, additional processing is not needed, and the deep groove ball retainer is very convenient and low in processing cost.
The above-mentioned embodiments only represent some embodiments of the present invention, and the description thereof is specific and detailed, but not to be construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention.
