Abstract
The utility model discloses a retainer and a ball bearing, and relates to the technical field of bearings. The retainer comprises an outer retainer ring beam (3) and a framework sealing ring (4), wherein the extending framework sealing ring (4) is arranged on the outer side surface of the outer retainer ring beam (3); the outer rim surface of the framework sealing ring (4) is in small-clearance fit with a step surface B (5) on the outer surface of an inner bearing ring (7) and a step surface A (2) on the inner surface of an outer bearing ring (1). The retainer is simple in structure and easy to process, and the cost of the bearing is effectively lowered.
Description
[technical field]
?the utility model relates to technical field of bearings, and specifically the utility model relates to a kind of retainer and ball bearing.
[background technique]
Known, the ball bearing of band sealing mainly contains ball, inner ring, outer ring, retainer and seal ring composition, conventionally seal ring is arranged between the inner ring and outer ring at bearing two ends, the sealing configuration of shape matched bearings, this sealing configuration, need to be at the seal groove of the Internal and external cycle both ends of the surface processing structure complexity of bearing, and not only work efficiency is lower, complicated operation, and cost is higher.
[model utility content]
In order to overcome the deficiency in background technique, the utility model discloses a kind of retainer and ball bearing, and simple in structure, be easy to processing, effectively reduce the cost of bearing.
For achieving the above object, the utility model adopts following technological scheme:
A kind of retainer, comprise retainer outer-ring beam and backbone sealing ring, on the outer side surface of retainer outer-ring beam, be provided with the backbone sealing ring of extension, the step surface B of the outer edge surface of described backbone sealing ring and bearing inner race outer surface and the step surface A of bearing outer ring internal surface are little Spielpassung.
Described retainer, described retainer outer-ring beam and backbone sealing ring are integrated setting.
Described retainer, described little Spielpassung is 0.5-0.8mm.
Described retainer, the pocket hole arranging on retainer outer-ring beam outer edge surface is the pocket hole with fore shaft.
A kind of ball bearing, comprise the bearing that two row same structures arrange, wherein an arbitrary row bearing comprises bearing outer ring, bearing inner race, rolling element and retainer described in the utility model, outside at bearing inner race is provided with bearing outer ring, described rolling element is arranged in the raceway between bearing inner race outer surface and bearing outer ring internal surface, and described retainer is disposed on a plurality of rolling elements in pocket hole uniformly.
Described ball bearing, the bearing of two described row same structure settings is for being set up in parallel.
Owing to having adopted technique scheme, the utlity model has following superiority:
Retainer described in the utility model and ball bearing, simplify the sealing configuration of bearing, save the seal ring of bearing face, avoid the seal groove of bearing inner race ferrule arrangement complexity, greatly improve Production of bearing efficiency, effectively reduce cost of production, increased the lubricated space of bearing inside simultaneously, extended the bearing lubrication life-span.
[brief description of the drawings]
Fig. 1 is structural representation of the present utility model;
In the drawings: 1, bearing outer ring; 2, step surface A; 3, retainer outer-ring beam; 4, backbone sealing ring; 5, step surface B; 6, rolling element; 7, bearing inner race;
[embodiment]
Can explain in more detail the utility model by the following examples, the utility model is not limited to the following examples;
A kind of retainer described in 1 by reference to the accompanying drawings, comprises retainer outer-ring beam 3 and backbone sealing ring 4, is provided with the backbone sealing ring 4 of extension on the outer side surface of retainer outer-ring beam 3, and described retainer outer-ring beam 3 and backbone sealing ring 4 are integrated setting; The pocket hole arranging on retainer outer-ring beam 3 outer edge surfaces is the pocket hole with fore shaft; The step surface A2 of the step surface B5 of the outer edge surface of described backbone sealing ring 4 and bearing inner race 7 outer surfaces and bearing outer ring 1 internal surface is little Spielpassung; Described little Spielpassung is 0.5-0.8mm.
A kind of ball bearing, comprise the bearing that two row same structures arrange, wherein an arbitrary row bearing comprises bearing outer ring 1, bearing inner race 7, rolling element 6 and retainer described in the utility model, be provided with bearing outer ring 1 in the outside of bearing inner race 7, described rolling element 6 is arranged in the raceway between bearing inner race 7 outer surfaces and bearing outer ring 1 internal surface, and retainer described in the utility model is disposed on a plurality of rolling elements 6 in pocket hole uniformly; The bearing of two described row same structure settings is for being set up in parallel.
Implement retainer described in the utility model and ball bearing, bearing identical two array structures is set up in parallel, wherein the outer side surface of the retainer outer-ring beam 3 of arbitrary row is provided with the backbone sealing ring 4 of extension, described retainer outer-ring beam 3 and backbone sealing ring 4 are integrated setting, the backbone sealing ring 4 arranging on described retainer outer-ring beam 3 outer side surfaces and the little Spielpassung of bearing outer ring 1 for 0.5-0.8mm, and on the outer edge surface of retainer outer-ring beam 3, be provided with the pocket hole with fore shaft, what energy was firm blocks rolling element 6, effectively plays positioning action; The utility model has been simplified the sealing configuration of bearing, save the seal ring of bearing face, avoid the seal groove of bearing inner race ferrule arrangement complexity, greatly improve Production of bearing efficiency, effectively reduce cost of production, the lubricated space that has simultaneously increased bearing inside, has extended the bearing lubrication life-span.
The utility model does not describe part in detail for prior art.
The embodiment who selects in this article for open goal of the invention of the present utility model, currently thinks suitablely, still, will be appreciated that, the utility model is intended to comprise that all belong to all changes and the improvement of the embodiment within the scope of this design and model utility.
