ABSTRACT:
A pulley with a variable working diameter, including two coaxial disks which are rotatable relative to one another, of which the one has a radial and the other at least one spiral-shaped guide groove. A plurality of support members with a segmentlike form are positioned between the disks and can be clamped with their front sides between the disks in different radial positions so that their radially outer peripheral areas define a polygonal path which is similar to a circle. The support members having projections engaged in the guide grooves of both disks so that relative rotation of the disks moves the support members radially for changing the respective circle diameter. Each support member--viewed in the direction of the axis of rotation of the disks--has the shape of an asymmetrical segment, preferably a circular-ring segment, with a longer and a shorter diagonal. An extension of the longer diagonal is spaced from but passes by on the same side of the axis of rotation of the disks as a perpendicular to a tangent on the spiral-shaped guide groove in the area of the support member.
