TITLE HOB CLAMPING SYSTEM ABSTRACT A tensioner having screw threads tightened by rotation of a hob drive (15) is used for applying clamping pressure to a hob (10) in a working position in a hobbing machine. The tensioner extend through the hob between the end supports (11 and 12) of the hobbing machine and has threads arranged so that a wrench system can hold part of the tensioner against rotation while the hob drive tightens the threads to a predetermined clamping torque. The tensioner can be a single draw rod (20) extending from driving end support (11), through hob (10), and into threaded engagement with idler end support (12); and the tensioner can include a hob mounting arbor (45) having threaded ends into which a pair of opposed tensioner rods (20 and 46) are threaded.
