Abstract
The utility model relates to an internal-diameter antifriction retainer. The diameter of an outer linear flange (2.1) of an inner ring (2) matching with a retainer body (1) is configured as D, the total width of the retainer is configured as H, the diameter of a pocket hole (1.2) of the cage (1) is configured as d, the width b of each end frame body (1.1) of the pocket hole is equal to (H-d)/2, the internal-diameter end surface of each end frame body is designed to be in a circular arc shape, and the internal diameter value of the each end frame body is equal to (D+2S); when a space between the circular arc internal-diameter end surface and an inner linear flange of an outer ring is S; and when the arc height h of the circular arc internal-diameter end surface is not larger than r, the value of the center distance between corresponding arc heights is equal to (D+2S+2h), and the radius r of curvature of the circular arc internal-diameter end surface is not less than (b/2). According to the internal-diameter antifriction retainer disclosed by the utility model, the circular arc internal-diameter end surface is in point contact with the outer linear flange of the inner ring so that the mutual contact friction is large reduced, the direct effect of antifriction is that the work stability of a rolling bearing is improved, the structure is simple, the process is easy, the weight of the retainer can be reduced, and the internal-diameter antifriction retainer is especially suitable for the rolling bearing rotating at a high speed.
Description
Technical field
The utility model belongs to technical field of bearings, especially a kind of internal diameter antifriction retainer.
Background technique
Common retainer is straight cylindrical surfaces at the internal diameter end face at its pocket Kong Chu two ends, the outer straight line rib of straight cylindrical surfaces and inner ring can be regarded short Oil Wedge Hydrodynamic Bearing as, and this straight cylindrical surfaces is that a kind of line contacts with the outer straight line rib of inner ring, the line contact can cause bearing to produce the larger frictional force of vibration in real work, and this frictional force can affect the flexibility of bearing rotary.
In addition; under desirable working state; because retainer does not have its fixing track and support; retainer can keep a kind of and the contactless suspension attitude of inner ring and outer ring; and in real work; due to the uncertain of suffered load and process existing error, the suspension attitude can occur certain eccentric and tilt usually, and the outer straight line rib of retainer and inner ring also can produce contact friction.
Summary of the invention
For addressing the above problem, the utility model has designed a kind of internal diameter antifriction retainer, this retainer is designed to the internal diameter end face at its pocket Kong Chu two ends circular-arc, this circular arc forms point with the outer straight line rib of inner ring and contacts, greatly reduce mutual contact friction, improved the working stability of rolling bearing.
For achieving the above object, the utility model adopts following technological scheme:
A kind of internal diameter antifriction retainer is set as D with the match outer straight line rib diameter of inner ring of retainer, and the retainer beam overall is set as H, and the pocket bore dia of retainer is set as d, the width b=(H-d)/2 of each end support body of pocket hole; The internal diameter end face of each end support body is designed to circular-arc, when described circular arc is S apart from gap between the outer straight line rib of inner ring, the internal diameter=D+2S of support body; When described circular-arc camber h≤r, the centre distance=D+2S+2h between two corresponding camber, the radius of curvature r of described circular arc 〉=b/2.
S described above is controlled at 0.05 ~ 2. 5 ㎜.
Above-mentioned retainer or made by metallic material, or made by nonmetallic material.
Owing to adopting technological scheme as mentioned above, the utility model produces following beneficial effect:
1, the internal diameter end face of each end supporting frame of retainer is designed to circular-arc, this circular arc forms point with the outer straight line rib of inner ring and contacts, and greatly reduces mutual contact friction, and the direct effect of antifriction is the working stability that has improved rolling bearing.
2, the retainer designed of the utility model can be applied to the rolling bearing of High Rotation Speed, and the rotating speed of rolling bearing is further improved.
3, of the present utility model simple in structure, its processing is uncomplicated, retainer weight saving.
Description of drawings
Fig. 1 is the outer straight line rib structure simplified schematic diagram of the utility model and inner ring.
In Fig. 1: the 1-retainer; 1.1-support body; 1.2-pocket hole; The 2-inner ring; 2.1-outer straight line rib.
Embodiment
The utility model is a kind of internal diameter antifriction retainer, be set as D with match outer straight line rib 2.1 diameters of inner ring 2 of retainer 1, retainer 1 beam overall is set as H, pocket hole 1.2 diameters of retainer 1 are set as d, the pocket hole count is several, these parameters are all the prerequisite basic parameters of rolling bearing, can design retainer of the present utility model according to these parameters.
The width b=(H-d)/2 of its pocket of retainer of the present utility model 1 hole 1.2 each end support body 1.1, be designed to the internal diameter end face of each end support body 1.1 circular-arc, when between the outer straight line rib 2.1 of described circular arc and inner ring, gap is S, internal diameter=the D+2S of support body 1.1, described S is controlled at 0.05 ~ 2.5 ㎜.When described circular-arc camber h≤r, the centre distance=D+2S+2h between corresponding camber, the radius of curvature r of described circular arc 〉=b/2.
This shows: circular arc described above forms point with the outer straight line rib 2.1 of inner ring and contacts, and greatly reduces mutual contact friction, and the direct effect of antifriction is the working stability that has improved rolling bearing.
Retainer of the present utility model or made by metallic material, or made by nonmetallic material, it is simple in structure, processes uncomplicatedly, and can alleviate the weight of retainer, is specially adapted to the rolling bearing of High Rotation Speed.
