A positive axial clutch including a first inner having a surface of revolution about the axis of rotation of the clutch, which surface is substantially a hyperboloid through every point on which two straight line generators may be drawn so as to lie wholly in the surface. A second outer race defined with the first inner race, an annular space between confronting surfaces of the races, one of which is the surface of revolution. A plurality of thrust transmitting rollers are disposed in the annular space between the races so as to engage with the surfaces thereof to make thrust transmitting contact between confronting surfaces for driven rotation of the first or second races in at least one direction, with each roller contacting the surface of revolution of the first inner race along a generator of the surface or a line which approximates to such a generator. The rollers are all similarly inclined with respect to radial planes. Means is provided at the interface between at least one end portion of each of the rollers and at least one of the races to permit slidable movement therebetween at least in a first direction while supporting the rollers axially thereof.

A positive axial clutch including a first member having a surface of revolution about the axis of rotation of the clutch, which surface is derived from a hyperboloid, a second member defining with the first member an annular space between confronting surfaces of the members, one of which is said surface of revolution, and a plurality of thrust transmitting rollers disposed in said annular space so as to engage with the surfaces to make thrust transmitting contact between confronting surfaces for driven rotation of said first or second member in at least one direction, said rollers each having a longitudinal rolling central axis, said hyperboloid from which said surfaces are derived being generated by using said central axis of said rollers as the straight line generators thereof, each roller contacting said surface of revolution of said first member along a generator of said surface or a line which approximates to such a generator, the rollers all being similarly inclined with respect to radial planes, means at an interface between at least one end portion of each of said rollers and at least one of said first and second members to permit slidable movement therebetween at least in a first direction while supporting the rollers axially thereof; wherein the surfaces approximate generally conical hyperboloidal surfaces having a diameter at one end portion of each member greater than the diameter at the other end portion of the same member; wherein said means at the interface between said rollers and at least one of said first and second members in an annular support member positioned on and supported by at least one of said members beneath said rollers at the portion of contact of said rollers with said surfaces corresponding to the larger diameter end of each member; wherein said annular support member is capable of slidable rotation relative to at least one of said members so as to freely support said rollers rotatably relative to at least one of said members.
