ABSTRACT:
A flexible hub apparatus for securing a power takeoff element to a shaft includes a hub formed of resilient material and having a first end and a second end and a hub spacing unit for selectively moving the hub between a shaft removal position and a shaft clamping position. The hub defines an inner circumference for receiving the shaft therein for clamping engagement by the hub. The first and second hub ends are movable relative to one another between the shaft clamping position in which the effective inner circumferential extent of the hub is such that the hub clamps the shaft and the shaft removal position in which the effective inner circumferential extent of the hub is such that the shaft is freely removable from the hub. The hub spacing unit includes a movable member disposed between the first and second hub ends for selective surface-to-surface engagement therewith and at least one of the engagement surfaces is tapered.
