Abstract
A continuously variable belt transmission device, including driving and driven pulley assemblies on parallel axes. Each pulley assembly includes an axially fixed and an axially movable pulley member with confronting conical face which define a V-shaped groove between them whose width is variable according to axial movement of the movable pulley member wherein the axial orders of the fixed and movable pulley members are opposite in the two pulley assemblies. An endless belt assembly is fitted in a power transmitting manner in the V-shaped grooves of the driving and driven pulley assemblies, and thus by alteration of the widths of the grooves the power transmission ratio can be varied. When the widths of the two V-shaped grooves of the two pulley assemblies are substantially equal, with the endless belt assembly being substantially taut between the pulley assemblies, the axial center of the V-shaped driving pulley groove of the driving pulley assembly is, relative to the axial center of the V-shaped driven pulley groove of the driven pulley assemblies, offset towards the axially movable driven pulley member along the axial direction. The maximum amount of skewing of the endless belt assembly is thereby reduced.
