Abstract

PURPOSE:To obtain the simple constitution of the captioned apparatus at low cost by forming each semicircular groove in which the center of rotation of a steel ball is automatically determined through the equilibrium of the forces at three points at which the steel ball contacts under pressure, on a driving-side member and a trailing-side member, in a stepless speed change gear in utilization of steel ball. CONSTITUTION:An input shaft 9 and an output shaft 10 are supported through bearings 33, 34, 36 and 37 onto the brackets 7 and 8 which constitute a part of a housing, and an input-side drive cone 28 which point-contacts with the outer periphery of a steel ball 21 and whose outer surface is curved in concaved form is installed at the edge of the input shaft 9 through a spline part 9a. An output- side drive plate 35 having a semicircular groove 35a which point-contacts with the steel ball 21 is fixed at the edge of the output shaft 10, and an outer ring 22 having a conical surface 22a which press-contacts with the steel ball 21 is fixed onto the inner peripheral surface of the housing 6. The input-side drive cone 28 is shiftable in the axial direction through a pin 31 and a positioning plate 29, by the revolution of a nut 32, and thus transmission ratio can be varied.
