Title: Variable diameter pulley
Inventor: HASUDA YASUHIKO
IPC: F16H55/56
Filed: 1998-06-19
Abstract: PROBLEM TO BE SOLVED: To prevent an excessive stress from being generated in the periphery of a connecting hole engaging with a first connecting shaft and to improve the durability of a diaphragm spring by permitting the first connecting shaft for transmitting torque only to transmit torque and the axial displacement of the diaphragm spring. SOLUTION: A power transmitting ring 6 on which a belt 7 is wound is held between a pair of pulley main bodies 2 and 3 so as to be decentered. A diaphragm spring 11 and an inertia member 42 for urging the power transmitting ring 6 toward a concentric side through the pulley main bodies 2 and 3 are included. The diaphragm spring 11 rotates integrally with both the pulley bodies 2 and 3 and with a rotating shaft 1 through a connecting member 12. To the connecting hole of the diaphragm spring 11, first and second connecting shafts 51 and 52 fixed to the connecting member 12 are fitted. The first connecting shaft 51 regulates only the circumferential rotation of the diaphragm spring 11. The second connecting shaft 52 regulates the axial displacement of the diaphragm spring 11.  The connecting shafts are divided into one for transmitting torque and one for regulating the axial displacement to reduce a load.
