Abstract
The utility model discloses a ball bearing retainer. The ball bearing retainer comprises a ring-shaped retainer main body, wherein a plurality of rolling ball mounting holes for freely rotary installation of rolling balls are formed in the ball bearing retainer, and a plurality of semi-circular oil storage grooves are formed in the end surface on one side of the ring-shaped retainer main body. The ball bearing retainer has the advantages that the disadvantage of insufficient inner storage space of the bearing is eliminated, grease leakage under a condition that the bearing rotates at high speed is effectively avoided and the service life of the bearing is greatly prolonged.
Description
Technical field
The utility model belongs to technical field of bearings, specifically refers to a kind of ball bearing retainer.
Background technique
Automobile tension wheel is owing to being subject to the restriction of installing space, product structure is generally very compact, and expansion tightening wheel bearing is a kind of important component of automobile tension wheel, its structure has generally comprised outer ring, inner ring, and be arranged at outer ring, between inner ring for keeping the retainer of a plurality of ball turns, because expansion tightening wheel operating mode is more severe, operating ambient temperature span is large, subzero 30, spend between 150 degree, and in working environment, there is mud, sand and dust, water is the impurity such as erosion even, in order to prevent impurity, invade bearing inside, and ensure the normal operation of bearing, the outer ring of bearing, on left and right end face between inner ring, can be provided with seal ring, and in seal ring, enclose lubricating grease.Yet expansion tightening wheel bearing turns round after a period of time under the operating mode of high temperature, High Rotation Speed, because bearing interior space is limited, grease is subject to operating on centrifugal force and occurs leaking fat phenomenon, has had a strong impact on the normal service life of bearing.
Summary of the invention
The purpose of this utility model is the shortcoming and defect existing in order to overcome prior art, and a kind of ball bearing retainer of effectively having avoided bearing to occur leaking fat problem under the operating mode of High Rotation Speed is provided.
For achieving the above object, the technical solution of the utility model is to include circular retainer main body, a plurality of spin mounting holes of installing that freely rotate for spin are set on this retainer, on a side end face of described retainer main body, are provided with a plurality of semicircular oil storage grooves.By this setting, utilize this oil storage grooves, when bearing high speed rotating, the guiding by lubricant grease by seal ring is stored in oil storage grooves, thereby effectively prevents that grease from revealing between Sealing and inner ring, has greatly extended the working life in later stage of bearing.
Further arrange be described oil storage grooves circumference uniform distribution in described retainer main body, described a plurality of spin mounting holes are upwards being evenly distributed between two adjacent oil storage grooves in week.By this setting, the storage of lubricant grease is distributed rationally, leakage-preventing effective.
Further arranging is that described oil storage grooves includes 8.
The utility model has the advantages that and eliminated bearing interior storage space deficiency, effectively avoided bearing under the operating mode of High Rotation Speed, to occur leaking fat phenomenon, greatly extended the working life in later stage of bearing.The product promotion of this application, to automobile current generator market, has obviously reduced client's complaint, for further market development provides solid technical support.
Below in conjunction with specification drawings and specific embodiments, the utility model is described further.

Fig. 1 the utility model embodiment stereogram;
Fig. 2 the utility model embodiment side view.
Embodiment
Below by embodiment, the utility model is specifically described, only for the utility model is further described, can not be interpreted as the restriction to the utility model protection domain.
Embodiment of the present utility model as shown in Figure 1-2, include circular retainer main body 1, a plurality of spin mounting holes 2 of installing that freely rotate for spin are set on this retainer 1, on one side end face of described retainer main body, be provided with a plurality of semicircular oil storage grooves 3, described oil storage grooves 3 circumference uniform distributions are in described retainer main body, described a plurality of spin mounting holes 2 are upwards being evenly distributed between two adjacent oil storage grooves in week, in addition, oil storage grooves 3 described in the present embodiment includes 8, so arrange, can ensure the intensity of retainer, also can make oil storage distribute rationally reliable.
This retainer of the present embodiment adopts that nylon material is one-body molded to be processed.
Claims (3)
1. a ball bearing retainer, include circular retainer main body, a plurality of spin mounting holes of installing that freely rotate for spin are set on this retainer, it is characterized in that: on a side end face of described retainer main body, be provided with a plurality of semicircular oil storage grooves.
2. a kind of ball bearing retainer according to claim 1, is characterized in that: described oil storage grooves circumference uniform distribution is in described retainer main body, and described a plurality of spin mounting holes are upwards being evenly distributed between two adjacent oil storage grooves in week.
