Abstract
The utility model discloses a lightweight high-speed bearing holder, a serial communication port, include: the cage comprises a cage body, wherein a plurality of cage single bodies and cage ball pockets are arranged between the inner diameter and the outer diameter of the cage body; a retainer bottom groove is formed in the arc bottom of the retainer ball pocket; the retainer shoulder of the retainer monomer is of an inward inclined fillet structure. The utility model discloses an at the grooved lightweight design in ball pocket bottom, reduce the influence that bearing moving centrifugal force caused to the holder, when the ball rotation simultaneously, store in the lubricating oil of tank bottom and can in time supply, improve lubricated, and improve the shoulder body of holder and compare 70% and kept the intensity of holder, increase fillet design and can effectively avoid making holder and bearing inner race internal diameter take place the friction because of the centrifugal force that high-speed rotation produced.
Description
Technical Field
The utility model relates to a holder field of making, concretely relates to lightweight high-speed bearing holder.
Background
The application working condition of the bearing in the high-speed motor is quite bad, and the rotating speed of the bearing reaches 30000r/min under the high rotating speed.
If a conventional bearing is used, the retainer is easily abraded and even damaged due to the friction between the centrifugal force and the outer ring. Meanwhile, under high-speed operation, the lubrication of the bearing is difficult to ensure.
SUMMERY OF THE UTILITY MODEL
In order to overcome the above-mentioned defects of the prior art, the present invention provides a light-weight high-speed bearing retainer.
In order to realize the utility model discloses an aim, the technical scheme who adopts is:
a lightweight high speed bearing cage comprising:
the cage comprises a cage body, wherein a plurality of cage single bodies and cage ball pockets are arranged between the inner diameter and the outer diameter of the cage body;
a retainer bottom groove is formed in the arc bottom of the retainer ball pocket;
the retainer shoulder of the retainer monomer is of an inward inclined fillet structure.
In a preferred embodiment of the present invention, the width of the retainer bottom groove is half of the width of the corresponding region retainer body.
In a preferred embodiment of the present invention, the depth of the retainer bottom groove is 30% of the depth of the corresponding region retainer body.
In a preferred embodiment of the present invention, the holder single body comprises a first and a second upper end surfaces connected to the holder pockets on both sides, and the first and the second upper end surfaces are connected to each other through a first and a second pocket claw outer spherical surface and a holder shoulder.
The beneficial effects of the utility model reside in that:
the utility model discloses an at the grooved lightweight design in ball pocket bottom, reduce the influence that bearing moving centrifugal force caused to the holder, when the ball rotation simultaneously, store in the lubricating oil of tank bottom and can in time supply, improve lubricated, and improve the shoulder body of holder and compare 70% and kept the intensity of holder, increase fillet design and can effectively avoid making holder and bearing inner race internal diameter take place the friction because of the centrifugal force that high-speed rotation produced.

Detailed Description
The light-weight high-speed bearing retainer shown in fig. 1-4 comprises a retainer body 100, wherein a plurality of retainer single bodies 8 and retainer ball pockets 1 are arranged between the inner diameter 7 and the outer diameter 5 of the retainer body 100; the arc bottom of the retainer ball pocket 1 is provided with a retainer bottom groove 6.
The width of the retainer bottom groove 6 is half of the width of the corresponding region retainer body 100, and the depth of the retainer bottom groove 6 is 30% of the depth of the corresponding region retainer body 100.
The retainer single body 8 comprises a first upper end surface 2 and a second upper end surface 2 which are connected with the retainer ball pockets 1 on the two sides, and the first upper end surface 2 and the second upper end surface 2 are connected with the retainer shoulder 3 through a first pocket claw outer spherical surface 4 and a second pocket claw outer spherical surface.
The retainer shoulder 3 of the retainer unit 8 is a fillet structure inclined inward.
The utility model discloses a set up the lightweight design of holder kerve 6 in holder ball pocket 1 bottom, reduce the influence that bearing moving centrifugal force caused to the holder, when ball (not shown in the figure) rotation, store in the lubricating oil of tank bottom and can in time supply, improve the lubrication simultaneously.
The specific structure of the bottom groove 6 of the retainer is arranged, so that the shoulder body ratio of the retainer body 100 is improved to 70%, and the strength of the retainer is maintained.
The retainer shoulder 3 can effectively avoid the friction between the retainer body 100 and the inner diameter of the bearing outer ring due to the centrifugal force generated by high-speed rotation by adding a fillet design.
Claims (4)
