    摘要： 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 extends 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.

    摘要： A gear hobbing machine, which comprises a hobbing spindle which is supported at its outboard end in a bearing assembly attached to but removable from a supporting member and including a bearing sleeve surrounding the spindle, and means between the sleeve and the spindle which normally occupies a position in which it eliminates any significant radical play between the sleeve and the spindle but is movable to an alternative position in which it permits movement of the sleeve with respect to the spindle to enable the hob to be changed.
