ABSTRACT:
A cylindrical viscous damper drive assembly for driving the matrix of a rotary regenerator heat exchange apparatus, the drive assembly including an annular ring-like driven sprocket loosely encircling the annular hub at one end of a drive shaft coupled to the matrix, the sprocket being drivingly coupled to the hub by a pair of axially spaced apart split ring torsion springs, each torsion spring being pinned at one end to an end of the hub and having a radially outward extending lip at its other end that projects into a socket in the sprocket to effect the driving connection between the sprocket and hub, a pair of O-rings being positioned in axially spaced apart relation to each other to effect a sealing engagement between the outer periphery of the hub and the inner periphery of the socket whereby to define therewith a sealed annular chamber which is filled with a viscous fluid that will provide, when relative rotational movement occurs between the sprocket and hub, a dampening force to reduce torque oscillations between the hub and the sprocket and, axially spaced apart shoulder means on the sprocket extending radially inward to be in interference relation with respect to the hub and the split ring torsion springs attached thereto to limit axial movement of the sprocket relative to the hub.
