Abstract
An arrangement for providing a driving connection between a shaft and an essentially annular member, such as a gear, sprocket, bushing or the like, in which the shaft is provided with spaced flats, at least at one end, and the bore of the power transmission member is provided with complimentary surfaces to receive the shaft, generally with a light press fit.
Claims4
A connecting arrangement comprising:
- a cylindrical member having a plurality of flat surfaces spaced around at least a portion of its periphery, each flat surface being spaced from an adjacent flat surface by an arcuate surface, the radius of which equals the radius of the cylindrical member, said flat surfaces being chordal surfaces of said cylindrical member;
- an annular member having a bore with a plurality of arcuate surfaces of at least two different radii and a plurality of flat surfaces;
- the radius of one group of arcuate surfaces of said annular member being substantially equal to the radius of the arcuate surfaces of said cylindrical member and being in engagement therewith, the flat surfaces of said annular member contacting juxtapositioned flat surfaces of said shaft, and said other arcuate surfaces of said annular member having a smaller radius than that of said one group and each such other arcuate surface being flanked by a flat surface of said bore.
An arrangement for drivingly connecting a power transmission part such as a gear or sprocket and the like to a shaft comprising:
- a cylindrical shaft having a plurality of flat surfaces spaced around at least a portion of its periphery, each flat surface being spaced from an adjacent flat surface by an arcuate surface, the radius of which equals the radius of the cylindrical shaft, said flat surfaces being chordal surfaces of said cylindrical shaft;
- a power transmission part having a central bore with a plurality of arcuate surfaces of at least two different radii and a plurality of flat surfaces said flat surfaces joining adjacent arcuate surfaces;
- the radius of one group of arcuate surfaces of said part being substantially equal to the radius of the arcuate surfaces of said shaft and being in engagement therewith, the flat surfaces of said part contacting juxtapositioned flat surfaces of said shaft, said other arcuate surfaces of said part having a smaller radius than that of said one group and each such other arcuate surface being flanked by a flat surface of said bore.
