An improved collar assembly (11) adapted for easing the disassembly of stacked members on a shaft (50) subjected to compressive loading is disclosed. The collar assembly (11) includes a pair of collar members (10,12) which are mounted contiguously abutting one another along a planar angulated interface. One of the collar (10) members defines a bore therethrough configured to closely correspond to the exterior diameter or exterior configuration of the shaft (50) in which the collar assembly (11) is to be mounted. The second collar (12) assembly defines a bore therethrough which is dimensioned to be substantially larger than the shaft (50) exterior configuration in which the assembly is to be mounted. The disparity in the bore sizes permits the second collar (12) to be displaced laterally as well as axially along the shaft with respect to the shaft (50) and along the planar interface of the two-collar members. The two-collar members (10,12) define the respective exterior engagement surface adapted to engage and otherwise abut against a member stacked on the shaft. The distance between the opposing engagement surfaces thereby adjustable dimensionally as the second collar member is displace along the surface of the first collar member. A cover (14), adapted to retain the two collars (10,12) in alignment one with the other, is configured to be positioned about the two collars. One or more jack screws (97) may be mounted within the second collar member (12) to releasably retain that member in a selected orientation vis-a-vis the shaft (50). <IMAGE> |
