<p>A clutch-brake unit incorporates a clutch disk pack, and a separate brake disk pack with an interposed piston unit which is coupled in one direction to engage the clutch and in the opposite direction to engage the brake. The housing is formed in three major sections which includes an input section generally enclosing the input shaft and the clutch pack. An output housing generally contains the output shaft and the brake pack, and an intermediate piston housing generally contains the actuated piston and associated fluid pressure inputs. The output shaft is provided with integral impellers and oil access apertures for delivering a constant supply of oil to the clutch and brake packs and for providing an inlet in which the oil may flow by centrifugal force when the output shaft is not turning. A heat exchanger consists of a heat exchange subassembly forming a series of finned tubes which assembly may be inserted in surrounding relation to the clutch pack. A shrouded fan assembly may be substituted where thermal capacity does not require internal cooling.</p> |
