Abstract
A transport unit for elongated hot metallic stock, includes a roll or roller having a cooling duct system near its periphery and radially oriented feed and discharge ducts for coolant; a journal pin extends from the roll or roller to one axial end thereof and carrying a gear, the journal pin is traversed by a bore extending into the interior of the roll or roller and is fluid conductively communicating with the coolant discharge duct; a gear transmission including a casing is provided and the journal pin is mounted for rotation by means of roller bearings in the casing, the transmission gear includes the gear on the journal pin so that the journal pin constitutes the output shaft of the transmission gear: a motor is secured to the casing and has its output shaft drivingly connected to the input shaft of the transmission gear; a feed tube for coolant extends through the bore and into the roller for fluid conductive connection with the radial feed duct and being connected to a coolant feed supply; additional cooling ducts traverse the casing particularly the surface thereof and is fluid conductively connected to the bore; the coolant is discharged from the duct system in the casing through a highest point.
