Abstract: An improvement in gear cutting methods and apparatus of the type in which a multiple-tooth gear is manufactured from a blank by the generation of successive tooth slots by a cutter which makes a plurality of cuts during the generation of each successive slot. The improvement comprises an alteration in the timed relationship between the cutting rate and the generating roll during successive tooth slot cutting operations such that the number of cuts made by the cutter differs from slot to slot. While the effective contours of successive tooth slots generated by this improved method and apparatus are substantially identical, their cutting patterns differ, resulting in substantial reduction in the noise produced by power transmission systems utilizing gears generated in this manner.

Abstract: An automatic electrohydraulic chamfering unit, which can be operated with a conveyor means or incorporated into an automated gear-generating machine, comprises upper and lower centering and clamping assemblies for retaining a workpiece therebetween, upper and lower chamfering assemblies for chamfering the tooth edges at the toe and heel of each tooth, an indexing assembly for successively aligning each tooth of the workpiece with the chamfering tools and an automatic control system which governs the operating sequence of the above components during the chamfering cycle. The upper and lower centering and clamping assemblies are actuated by the control system to permit rotational movement of a workpiece during the indexing portion of the chamfering cycle and to firmly lock a workpiece in a fixed position during the chamfering portion of the cycle. The upper and lower chamfering assemblies are mounted on the chamfering unit so that the chamfering assemblies can be independently adjusted relative to the centering and clamping assemblies along the three major axes and about one of the axes for locating the chamfering assemblies relative to the workpiece. The indexing assembly through the reciprocating movement of a spring-biased finger which is received between the workpiece teeth indexes a workpiece by movement of the finger parallel to the axis of rotation of the workpiece. Scales are provided on the indexing assembly, the chamfering assemblies and mountings to facilitate initial and subsequent adjustments of the various components of the chamfering unit.

Abstract: An improved cradle is provided in a gear cutting machine so that bevel gears can be cut by a novel method which involves controlled axial movements of the cradle within its housing toward and away from a work spindle. In addition to providing conventional rotational movements to the cradle, there is provided a means for axially reciprocating the cradle within its housing in a timed relationship with rotations of a work spindle and with rolling movements of the cradle. The cradle includes a cylindrical surface which is journaled within a cradle housing, and hydraulically operated pistons function to advance the cradle axially toward a work spindle. Return movements of the cradle, away from a work spindle, are dictated by a crank member which is oscillated back and forth to accommodate axial movements of the cradle. The crank member derives its oscillating movements from a first cam and follower means associated with a drive means of the gear cutting machine. In addition, a second cam and follower means, which also effects axial movement of the cradle, may be provided for controlling helical motion of a cutter during a cutting operation. The second cam and follower means can override the effects of the first cam and follower means, and the second cam and follower means derives its movements from rotational movements of the cradle.

Abstract: A method for resharpening cutting blades for gear cutting machines in such a way that a front face of each blade is preserved without removal of material therefrom. A cutter head assembly for gear cutting machines is described as including an arrangement of blade-receiving slots at angles to a longitudinal axis of the assembly so as to permit removal, resharpening, and replacement of blades into such slots without removing any stock from the cutting faces of the blades.

Abstract: A gear shaping machine for cutting gears with generation effected by a rotatable work holder and a tool holder carrying a cutting tool adapted to be reciprocated. The tool holder is mounted to a translatable supporting structure, the rate or speed of such translational movement during generation being selectively variable to produce variable ratio gears. Separate and independent power sources are provided for the generating train, for actuating the cutting tool, and for a servo mechanism which controls the reversing operation of the generating train. The tool holder is slidably mounted in a cradle housing for movement in a direction along its own axis (and at right angles to said translational movement) to permit production of an oversized tooth or teeth in the gear or gear sector being cut. Means are also provided to effect insertion and withdrawal of the cutting tool relative to the work for each individual cutting stroke. A counterweight mechanism is provided in operative connection to the structure for reciprocating the cutting tool to provide a smoother and faster cutting stroke.

Abstract: A transfer mechanism for delivering and receiving pinion workpieces to and from a pair of double-station bevel gear cutting machines in timed relation to their operation. The mechanism also includes storage bank means in which partiallyprocessed workpieces may be accumulated, thereby permitting the double-roughing machine to continue operation when the doublefinishing machine must be temporarily shutdown for cutter replacement, daily maintenance, etc., and similarly providing a continuing supply of workpieces to the double-finishing machine when the double-roughing machine is temporarily shutdown.

Abstract: In a bevel gear making machine, a workhead assembly mounts the work for rotation about a vertical or generally vertical axis and in a stable secure position, permitting multiple movements of the workhead for various purposes, as will be understood. The workhead assembly is mounted between and supported by two spaced and parallel upstanding side walls of the machine frame and includes a workhead, a swinging base, and a slidable base connected together so that the workhead assembly is slidable back and forth in a direction parallel to the side walls. The side walls, and the swinging base and workhead are pivotable about an axis extending between the side walls. The horizontal slidable motion of the workhead adapts it for movement between work loading and unloading and cutting positions, and the pivotal movement of the workhead enables the axis of rotation of the work spindle to be adjusted so as to be in a vertical or somewhat inclined from the vertical position during cutting operations.
