Abstract
The utility model discloses a non-contact-type special-shaped wedge block overrunning clutch. The outer diameter d of an inner ring (1) is an outer rolling path. The inner diameter D of an outer ring (2) is an inner rolling path. A plurality of special-shaped wedge blocks (3) are arranged in a configured mode in the gap formed by the inner rolling path and the outer rolling path. The inclined direction of each special-shaped wedge block is the same. The upper portions of each two adjacent special-shaped wedge blocks are separated at an interval through a holder. Two end faces of each special-shaped wedge block are respectively and tightly pressed on the outer rolling path through a spring. The outer convex side of each special-shaped wedge block and the inner rolling path of the outer ring are in a non-contact state under the effect of pressing force of the spring. Excessive rolling-over of the special-shaped wedge blocks will not occur under the effect of an auxiliary supporting face, and therefore a certain tiny gap is kept between each special-shaped wedge block and the inner rolling path of the outer ring. The non-contact-type special-shaped wedge block overrunning clutch has the advantages of being simple in structure and small in appearance and size and achieving a bi-directional overrunning function.
Description
Technical field
The utility model belongs to the Clutch Technology field, refers more particularly to a kind of contactless special-shaped voussoir free wheel device.
Background technique
The CKS type is a kind of common contact-type free wheel device, and the working principle of contact-type free wheel device is: inner ring also rotates the outer ring clockwise or when rotating counterclockwise synchronously, and how to rotate its outer ring and all can not rotate when the outer ring is subjected to moment of face to make the time spent inner ring.The contact-type free wheel device can produce friction and wear when running up, reduced the operating life of contact-type free wheel device.
Summary of the invention
For prolonging the operating life of clutch, the utility model has designed a kind of contactless special-shaped voussoir free wheel device, this contactless special-shaped voussoir free wheel device can rotate and transmitting torque its outer ring clockwise or when rotating counterclockwise synchronously at inner ring, and can be clockwise and freely rotate counterclockwise but transmitting torque not in its outer ring when inner ring does not rotate, and special-shaped voussoir and outer ring are contactless state.
For achieving the above object, the utility model adopts following technological scheme:
A kind of contactless special-shaped voussoir free wheel device, the outside diameter d of inner ring is outer raceway, the inside diameter D of outer ring is interior raceway, described D＞described d, in described raceway and described outside dispose several special-shaped voussoirs in the gap that forms of raceway, the true dip direction unanimity of each special-shaped voussoir is implemented equidistant the isolation by retainer between the first half of adjacent special-shaped voussoir, and the both ends of the surface of several special-shaped voussoirs are pressed on it on described outer raceway by spring respectively.
The upper-end surface of above-mentioned special-shaped voussoir is outer convex surface, the lower end surface of abnormity voussoir is made of interior convex surface and secondary support surface, the both ends of the surface of abnormity voussoir are provided with horn-like groove, the radius of curvature of outer convex surface is less than described D/2, the radius of curvature of interior convex surface is less than described d/2, secondary support surface and interior convex surface intersect, and in the horn-like groove spring are set.
Owing to adopt technological scheme as mentioned above, the utility model produces following beneficial effect:
1, overall structure of the present utility model is simple, boundary dimension is little, has realized the bidirectional overtaking function of clutch.
2, the utility model is surmounting under the state, raceway is to be contactless state all the time in abnormity voussoir and the outer ring, avoid the friction phenomenon that in running up special-shaped voussoir produces owing to raceway in the contact outer ring and caused wearing and tearing therefrom or the heating phenomenon, thereby prolonged working life of the present utility model.
Description of drawings
Fig. 1 is a structural representation sketch of the present utility model.
Fig. 2 is that sketch is amplified in the part at A place among Fig. 1;
Fig. 3 is the stereochemical structure simplified schematic diagram of special-shaped voussoir;
Among the above-mentioned figure: 1-inner ring; 2-outer ring; 3-special-shaped voussoir; 3.1-outer convex surface; 3.2-interior convex surface; 3.3-secondary support surface; 3.4-horn-like groove; 4-retainer; 5-spring.
Embodiment
The utility model is a kind of contactless special-shaped voussoir free wheel device, raceway is in contactless state all the time in abnormity voussoir and the outer ring, avoid the friction phenomenon that in running up special-shaped voussoir produces owing to raceway in the contact outer ring and caused wearing and tearing therefrom or the heating phenomenon, thereby prolonged the working life of contactless special-shaped voussoir free wheel device.
In conjunction with Fig. 1, the outside diameter d of inner ring 1 is outer raceway, and the inside diameter D of outer ring 2 is interior raceways, described D＞described d.
In conjunction with Fig. 2, the utility model in described raceway and described outside dispose several special-shaped voussoirs 3 in the gap that forms of raceway, the true dip direction unanimity of each special-shaped voussoir 3, implement equidistant the isolation by retainer 4 between the first half of adjacent special-shaped voussoir 3, the both ends of the surface of several special-shaped voussoirs 3 are pressed on it on described outer raceway by spring 5 respectively.
In conjunction with Fig. 3, special-shaped voussoir of the present utility model 3 its upper-end surfaces are outer convex surface 3.1, the lower end surface of abnormity voussoir 3 is made of interior convex surface 3.2 and secondary support surface 3.3, the both ends of the surface of abnormity voussoir 3 are provided with horn-like groove 3.4, the radius of curvature of outer convex surface 3.1 is less than described D/2, the radius of curvature of interior convex surface 3.2 is less than described d/2, and secondary support surface 3.3 intersects with interior convex surface 3.2, in the horn-like groove 3.4 spring 5 is set.
Because spring 5 is pressed on several special-shaped voussoirs 3 on the outer raceway of inner ring 1 by horn-like groove 3.4, therefore the spring 5 special-shaped relatively voussoir 3 of surface of contact that compresses horn-like groove 3.4 has upwarping of several angle, can make spring 5 be difficult for the generation obscission like this in the horn-like groove 3.4 of packing into.
Special-shaped in addition voussoir 3 is under the effect of spring 5 impacting forces, outer convex surface 3.1 is contactless state with outer ring 2 interior raceways, and excessive upset can not take place in special-shaped voussoir 3 under the effect of secondary support surface 3.3, makes special-shaped voussoir 3 keep certain micro-gap with outer ring 2 interior raceways all the time.
Bidirectional overtaking is meant:
When inner ring rotates the clutch transmitting torque in its outer ring clockwise or when rotating counterclockwise synchronously;
Its outer ring can freely be rotated clockwise or counterclockwise when inner ring is motionless, and the clutch bidirectional overtaking is transmitting torque not.
