Abstract
A transmission comprises a rotary input member, a rotary output member and a housing. Disposed in the housing is at least one rolling member such as a ball for transmitting a rotary movement between the rotary input and output member. The rolling member is arranged between at least first and second substantially circular tracks forming a gap that decreases in the peripheral direction. The rolling member is held in contact at a drive rolling radius with the one track and at a driven rolling radius with the other track, in the decreasing gap, by a positive-action guide.
Claims9
A transmission comprising a housing, a rotary input member, a rotary output member, at least a first and a second at least substantially circular track means forming therebetween a gap which decreases in the peripheral direction, at least one rolling member arranged rollably between said track means and adapted to transmit rotary movement between the rotary input member and the rotary output member, a positive-action means adapted to hold the rolling member in contact at a drive rolling radius with one of said first and second track means and at a driven rolling radius with another of said first and second track means in said decreasing gap, steplessly adjustable adjusting means for adjusting the spacing between contact location of the rolling member with said one of said first and second track means and said other of said first and second track means, and auxiliary transmission means operatively associated with at least one of said first and second track means.
A transmission comprising:
- a rotary input member;
- a rotary output member;
- first and second at least substantially circular rolling track means each operatively associated with respective ones of said rotary input member and said rotary output member and disposed one within the other in eccentric relationship with each other thereby to define therebetween a gap whose width in a radial direction relative to said rotary input and output members varies in the peripheral direction of the gap;
- at least one rolling member arranged rotatably in said gap between said first and second track means for rolling contact therewith, thereby to transmit a rotary movement between the track means and accordingly between the rotary input and output members;
- and a means adapted to urge said rolling member into contact at a drive rolling radius with one of said first and second track means operatively associated with the rotary input member and at a driven rolling radius with the other of said first and second track means operatively associated with the rotary output member, steplessly adjustable adjusting means for adjusting the spacing between contact locations of the rolling member with said one of said first and second track means and said other of said first and second track means, and auxiliary transmission means operatively associated with at least one of said first and second track means.
