Title:
STEPLESS SPEED CHANGE FREE WHEEL
Document Type and Number:
Japanese Patent JPS5578822
Kind Code:
A
Abstract:
PURPOSE:To simplify the construction, by applying a multi-free wheel for the stepless speed change wheel, and performing an operation of stepless speed change in the method of transmission between ratchet tooth and up-down movable hook. CONSTITUTION:With a toothed part 20 rotated by a chain 19, a ring-shape unit 13 rotates in one unit. Rotation of the ring-shape unit 13 makes an engagement between a ratchet tooth 14 and a hook 15 of a slider 8b, to rotate a disk 5. When rotated to an amount of prescribed angle, the hook 15 comes to be contacted to a pressing substance 18 to disengage the ratchet tooth 14, causing the disk 5 to be not in rotation. Each slider 8, capable of sliding within the guide hole 7, moves a ring-shape substance 21 to provide an eccentricity with respect to the shaft 1, thus can be steplessly changed the rotational speed.
