Abstract
Abstract An overrunning clutch of the type having a clamp roller with a first coupling portion which is provided with clamp ramps for the rollers and a second coupling part which forms a cylindrical running surface or journal and a cage which is provided with axially displaced lateral disks of annular shape between which the clamp rollers and associated compression springs are disposed. The construction is such that the clutch can be assembled even when both the two shafts or the like with which the clutch has to be connected are already fixed and in position. To this end the contour of the first disk facing the first coupling portion is essentially cylindrical while the corresponding contour of the second disk is provided with additional projections which support the first coupling part in recesses of the first coupling part after the cage has been assembled.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
176 words
An overrunning clutch, comprising in combination, a plurality of circumferentially spaced clamp rollers; an outer coupling element and an inner coupling element, one of said coupling elements being provided with clamp ramps for said clamp rollers, the other of said coupling elements forming a cylindrical running surface for said clamp rollers; a cage arranged between said outer and said inner coupling elements and including a pair of lateral disks of annular shape and which are axially spaced with respect to each other with said clamp rollers located therebetween; and a plurality of expansion springs each located between said disks and intermediate two circumferentially spaced ones of said clamp rollers, the contour of a first one of said disks facing said one coupling element being of substantially cylindrical shape and the other disk having a corresponding contour but being provided with projections extending beyond its contour, said one coupling element having recesses and said projections of said other disk bearing against said recesses when said cage is assembled and arranged between said outer and inner coupling elements.
Claim 2
Dependent Claim
176 words
An overrunning clutch, comprising in combination, a plurality of circumferentially spaced clamp rollers; an outer coupling element and an inner coupling element, one of said coupling elements being provided with clamp ramps for said clamp rollers, the other of said coupling elements forming a cylindrical running surface for said clamp rollers; a cage arranged between said outer and said inner coupling elements and including a pair of lateral disks of annular shape and which are axially spaced with respect to each other with said clamp rollers located therebetween; and a plurality of expansion springs each located between said disks and intermediate two circumferentially spaced ones of said clamp rollers, the contour of a first one of said disks facing said one coupling element being of substantially cylindrical shape and the other disk having a corresponding contour but being provided with projections extending beyond its contour, said one coupling element having recesses and said projections of said other disk bearing against said recesses when said cage is assembled and arranged between said outer and inner coupling elements.
Claim 3
Dependent Claim
27 words
Clutch as defined in claim 1, wherein said outer coupling element is provided with said clamp ramps and said inner coupling element forms said cylindrical running surface.
Claim 4
Dependent Claim
27 words
Clutch as defined in claim 1, wherein said inner coupling element is provided with said clamp ramps and said outer coupling element forms said cylindrical running surface.
Claim 5
Dependent Claim
25 words
Clutch as defined in claim 1, wherein said clamp ramps are each provided with a cylindrical portion which radially supports said disks of said cage.
Claim 6
Dependent Claim
38 words
Clutch as defined in claim 4, wherein said cylindrical portion of said clamp ramps has a steeply falling portion to provide shoulders which serve as bearing for the projections of said other disk when said cage is assembled.
