| 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. | ||||||

| This invention pertains to a rack and pinion type steering gear for an automobile and a method for cutting rack teeth in the gear. The gear comprises a housing, a pinion rotatably supported within the housing and operatively connected to a steering wheel and a rack bar supported within the housing for slidable movement in the axial direction and rotation and provided with rack teeth in engagement with the pinion. The rack teeth are formed on the rack and along a varying pitch line so that the axial movement amount of the rack varies as the pinion rotates. | ||||||
