Abstract
A heat-dissipating coupling securing first and second shaft sections together for co-rotation and inhibiting heat transfer between the shaft sections. In an exemplary embodiment, the coupling includes a first coupling half secured to the first shaft section, and a second coupling half secured to the second shaft section. A plurality of air ducts extending generally transversely of the rotational axis of the shafts are formed between the first and second coupling halves. The ducts may be formed by grooves in the first coupling half, which are closed by a planar surface of the second coupling half. The ducts extend generally radially, and may be straight, or curved concavely or convexly with respect to the direction of the rotation of the shaft sections. Air may be supplied to the air ducts by providing one of the shaft sections as a hollow shaft in fluid communication with the coupling. Alternatively, air may be supplied to the ducts via a plurality of air inlet holes formed in the coupling itself.
