Method and a jig for mounting a stack of belleville springs

摘要

A method and a jig for mounting of a stack of Belleville springs about a shaft. The individual springs of the stack are first positioned over the shaft. A jig is then placed over the shaft and the springs and has at least one axially extending pressure bar that is radially inwardly biased to urge the inner circumferences of all the springs into contact with axially aligned points on the surface of the shaft. The springs are then compressed using a compression element while they are still urged by the pressure bar against the shaft. Finally, to retain the springs on the shaft and maintain the springs in compression, a split retaining clip is pressed onto to the shaft until it engages in a groove.
