Abstract: A drive shaft coupling support assembly includes a support beam mounted on a roller support and a housing movable along the beam between use and non-use positions. The housing includes a camming mechanism that can engage and securely hold the drive, shaft in a stationary position relative to the roller support to enable the replacement driven shaft to be readily re-engaged with the drive shaft. The camming mechanism is operable without the use of any tools. and the support assembly is able to be secured directly to a roller support to minimize the complexity of the assembly utilized to hold the drive shaft.

Abstract: A power transmission coupling that includes a drive shaft hub selectively connectable to a driven shaft hub. The drive shaft hub includes a number of ball bearings disposed within bores in the drive shaft that are selectively engageable within a groove disposed on the driven hub. The bearings are selectively locked within the groove by a sleeve movable disposed around the drive hub over the bearings. The drive hub also includes a key secured thereto that is selectively received within notches or apertures formed in the driven hub to mechanically engage the drive hub with the driven hub for effective power transmission via the coupling.
