Abstract:
1. A rotary carousel apparatus for storing items on shelves comprising: a stationary base for supporting one or more rotating components; a central column fixed relative to the base, the central column having a central axis extending along a longitudinal length of the central column; a rotatable first drive plate configured to rotate about the central axis; at least one rotatable second drive plate configured to rotate about the central axis; at least one torque tube assembly directly or indirectly coupled to the rotatable first drive plate and the at least one rotatable second drive plate for torque transmission between the rotatable first drive plate and the at least one rotatable second drive plate, the at least one torque tube assembly operative for rotational movement with a rotation of the rotatable first drive plate and the at least one rotatable second drive plate; a drive assembly operatively coupled to at least one of the rotatable first drive plate and the at least one rotatable second drive plate; and at least one shelf connected to the at least one torque tube assembly, wherein rotation of the drive assembly causes a corresponding rotation of one of the rotatable first drive plate and the at least one rotatable second drive plate connected thereto, and a rotation of the other of the rotatable first drive plate and the at least one rotatable second drive plate through the at least one torque tube assembly, and wherein the drive assembly is connected to at least one of the rotatable first drive plate and the at least one rotatable second drive plate by a drive hub and a flexible ring disposed between the drive hub and at least one of the rotatable first drive plate and the at least one rotatable second drive plate to compensate for any misalignment conditions between the drive assembly, the drive hub, and at least one of the rotatable first drive plate and the at least one rotatable second drive plate and limit backlash between the drive hub and at least one of the rotatable first drive plate and the at least one rotatable second drive plate.
