Title:
STEPLESS SPEED CHANGE DEVICE
Document Type and Number:
Japanese Patent JP2015001266
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a stepless speed change device capable of reducing a load onto a bearing by restraining vibration.SOLUTION: A connecting rod 15 of a stepless speed change device 1A comprises an expansion mechanism 21 for changing a distance Lcon between an input side fulcrum P3 and an output side fulcrum P5 according to a load applied to the connecting rod 15. When an oscillation link 18 does not transmit a driving force to an output shaft 3, the distance Lcon satisfies conditional expressions (1) and (2). In the expressions, Lp is a distance between a rotation center axial line P1 of an input part and a rotation center axial line P4 of the output shaft 3, R1 is a distance between the rotation center axial line P1 of the input part when a rotation radius of a rotation radius adjusting mechanism 4 is a predetermined rotation radius and the input side fulcrum P3, and R2 is a distance between the rotation center axial line P4 of the output shaft 3 and the output side fulcrum P5.
