    摘要： A machine for cutting the teeth of a rack for a variable ratio rack and pinion steering gear employing a helical pinion having a plurality of identical teeth engaged with a rack having some tooth gaps of varying form and angular disposition to the rack axis, the machine having a spindle carrying a tool with a single cutting tooth having cutting edges which lie on the surface of a single tooth of the helical pinion; the spindle is arranged for helical reciprocation in a housing between two predetermined limits about a mid position in which the tool is directed normally to the plane of the teeth of the rack, a rack holding fixture, the fixture or the housing being moveable with a relative translatory curvilinear motion during the cutting of a gap of the rack, the motion for any one gap being a part of the locus of the helical pinion when slid without rotation in the same gap of the rack.

    摘要： A gear hobbing machine having a gear train interconnecting a hob and a workpiece to be machined by the hob, the gear train being disconnectable to permit of cutting a stationary workpiece by a milling cutter substituted for the hob, a subsidiary motor operable to impart an increment of indexing rotation to the workpiece between successive cutting operations of the milling cutter, an index plate geared to a table supporting the workpiece and arranged when the milling cutter is in operation to perform a predetermined integral number of revolutions for each indexing movement of the workpiece, a bolt which is engageable with the index plate to lock the table against rotation, and a counter for counting the rotations made by the index plate when the bolt is withdrawn and causing arrest of the index plate and re-engagement of the bolt after the predetermined number of revolutions of the index plate have been performed.
