Title:
STEPLESS SPEED-CHANGE GEAR
Document Type and Number:
Japanese Patent JPS6081564
Kind Code:
A
Abstract:
PURPOSE:To reduce power loss and vibration, by a method wherein a nonuniform-rotation crank mechanism and a one-way clutch are intermediately provided between an input intermediate gear and an output intermediate gear, and one rotational phase of the crank mechanism is made to be different from another. CONSTITUTION:The nonuniform-rotation crank mechanism 18 and the one-way clutch 16 for transmitting power only from the input side to the output side are intermediately provided between the input intermediate gear 6 and an output intermediate gear 17, and at least one rotational phase of the crank mechanism 18 is made to be different from another rotational phase of the mechanism. Accordingly, since power is transmitted mainly through the gears, power loss is reduced, and since nonuniform rotation is obtained by the rotating motion of the crank mechanism 18, generation of vibration at a high-speed rotation can be reduced.
