ABSTRACT:
A device for automatically changing the speed ratio between a drive shaft and a driven shaft, including a pair of pulleys mounted on the drive and driven shafts and each having two opposing flanges of truncated cone shape, the pulleys being linked by a V-belt and one pulley being loaded with centrifugally displaceable weights for the speed-change operation.
One of the flanges of each pulley is provided with a cover plate having a flat surface portion perpendicular to the rotational axis in face-to-face relation with a truncated-conical surface of the flange. Centrifugally displaceable weights in the form of rollers are located in contact with and between the flat surface portion and the truncated-conical surface portion displaceably radially outward for the speed-change operation. Each roller is constituted by a pair of cylindrical members fixed in opposite end portions of a short shaft and a cylindrical rotary member rotatably mounted in the middle portion and having an outer diameter slightly greater than the cylindrical members. The roller is held in rolling contact with the truncated-conical surface portion of the flange at the opposite end portions and with the flat surface portion of the cover plate in the middle portion to preclude sliding resistance.
