Balancing of a continuous variable clutch assembly

Abstract

A continuous variable clutch is provided. The continuous variable clutch includes a first sheave member and a second sheave member. The first sheave member includes a first central hub and a first conical-faced surface extending radially from the first central hub. The second sheave member includes a second central hub and a second conical-faced surface that extends radially from the second central hub. The second central hub of the second sheave member is received in a cavity of the first central hub such that the first conical-faced surface of the first sheave member facing the second conical-faced surface of the second sheave portion. The second central hub moving axially within the first central hub based on an amount of torque on the continuous variable clutch. The first sheave member and the second sheave member further forming a central passage to receive an input shaft of a transmission.

1 . A method of balancing a clutch, the method comprising:
 mounting an assembled clutch on a test shaft;   rotating the test shaft;   determining if the assembled clutch is balanced; and   when the assembled clutch is determined not to be balanced, balancing the assembled clutch before engaging the assembled clutch with an input shaft of a transmission.   
     
     
         2 . The method of  claim 1 , wherein balancing the assembled clutch further comprises:
 determining a location to remove material of the clutch;   determining an amount of material to be removed; and   removing the determined amount of material from the clutch at the determined location.   
     
     
         3 . The method of  claim 1 , wherein removing the determined amount of material at the determined location further comprises:
 drilling out the determined amount of material at the determined location.
