ABSTRACT:
A viscous coupling for a drive shaft has an elongated tubular first shaft and an elongated cylindrical second shaft extending into and cooperating with the first shaft to define a cylindrical clearance therebetween. Bearings for accommodating both relative rotation and axial displacement of the first and second shafts are interposed therebetween at opposite ends of the clearance. Seals are associated with the bearings to hermetically seal the ends of the clearance, which is filled with a viscous fluid. The viscous resistance of the fluid to rotation of one shaft relative to the other provides a means of transmitting torque therebetween.
