Claims

[Claims for Utility Model Registration] A V-groove is formed between a fixed pulley having a conical surface and fixed to the drive shaft, and a fixed pulley having a conical surface similar to the fixed pulley. a driving pulley including a movable pulley that is movably attached in the axial direction of the drive shaft and moved in a direction toward and away from the fixed pulley by a moving means; a fixed pulley having a conical surface and fixed to the driven shaft; It has a conical surface similar to the fixed pulley, forms a V-groove between it and the fixed pulley, is attached to be movable in the axial direction of the driven shaft, and is moved in a direction toward and away from the fixed pulley by a moving means. a driven pulley consisting of a movable pulley; each V of this driven pulley and the driving pulley;
In a V-belt type continuously variable transmission that has a V-belt wrapped around a groove and transmits the rotation of the drive shaft to the driven shaft in a steplessly variable manner, movement of the movable pulley on the drive pulley side or the driven pulley side. As a means, a slider shaft is fixedly provided along the outer periphery of the shaft on the opposite side to the conical surface of the movable pulley, and has a male screw threaded in the same direction as the rotating direction of the V-belt on the outer periphery of the slider shaft; It has a female thread on the inner circumferential surface that engages with the male thread of the slider shaft, and is in contact with the surface opposite to the conical surface of the movable pulley via a bearing so that it can be threaded on the slider shaft. The slider gear is provided with a slider gear and a slider gear drive means meshed with the outer peripheral edge of the slider gear, and when the slider gear is rotated by the drive of the slider gear drive means, the slider gear moves on the slider shaft. 1. A pulley speed drive device for a V-belt type continuously variable transmission, characterized in that the movable pulley can be moved in a direction toward and away from a fixed pulley.
