Title:
CONTINUOUS VARIABLE SPEED CHANGE GEAR
Document Type and Number:
Japanese Patent JP2017032145
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a method for transmitting a power force through a speed change gear having a plurality of balls respectively comprising tiltable axis and rotating around the axis.SOLUTION: A method of this invention comprises the steps for receiving an input power force through a rotatable input disc arranged adjacent to balls and contacted to each of the balls; determining a desired output power force of a speed change gear; adjusting inclination angles of a plurality of balls on the basis of one of a desired speed ratio or a torque ratio corresponding to a desired output power force; and routing a power force received through one of the output disc or a rotatable idler. The output disc is arranged to be adjacent to the balls at an opposite side of the input disc and contacted with each of the balls. The idler is arranged to be contacted with each of the balls inside in a radial direction of each of the balls. The idler is connected to an idler shaft receiving an output power force from the idler and adapted for feeding out the output power force from the speed change gear.SELECTED DRAWING: Figure 1
