摘要： An apparatus is disclosed for performing thermomechanical processing of gears in which precise control of the thermal, metallurgical and mechanical action during the forming process is maintained. The apparatus comprises an induction heating system which reaustenitizes the surface of the gear with minimum decarburization, a material transfer system which provides timely operations on the work piece, tooling and fixture adjustments which provide accurate initial conditions for forming, and a process control architecture that provides the precise sequence and timing necessary to achieve metallurgically sound and dimensionally accurate gears. Using this invention the induction heating cycle can be controlled from the peak, average or minimum gear surface temperature detected with a high response optical pyrometer. An inert environment is maintained around the workpiece during the induction heating and transfer to quenching above the M.sub.s temperature. Both through-feed and in-feed motion are simultaneously controlled by load, position and velocity transducers which provide feedback information to a supervising microprocessor. This apparatus produces metallurgically sound and accurate gears.

摘要： A full form net shape roll finished contacting machine element such as a gear or sprocket is produced from a near net shape workpiece of wrought or forged steel including teeth with an initial outer peripheral contoured surface, each having a tooth flank with a nominally involute surface and a root/fillet region with a trochoidal surface. A rolling die is rotatably supported on a first axis. With the workpiece rotatably supported on a parallel distant second axis, the rolling die is advanced in an in-feed direction to meshingly engage with the workpiece. The involute surface of each tooth of the rolling die engages the involute surface of a mating tooth of the workpiece and the tooth tip of the rolling die engaging the trochoidal root/fillet surface between adjacent mating teeth of the workpiece to effect material flow along the outer peripheral contoured surface. This process continues for all of the teeth of the workpiece.

摘要： A method and apparatus disclosed for cost-effective net shape precision ausform finishing the engagement surfaces of ball and roller bearings, for enhancing the surface strength and durability of bearing inner and outer races. The method consists of induction heating to austenitize the contacting surface layers of rolling element bearing races, followed by martempering (or marquenching), and then net shape roll finishing of the induction heated contacting surface layers in the metastable austenitic condition to finished dimensional accuracy requirements, and finally cooling to martensite. The apparatus utilizes a fixed vertical through-feed axis for the workpiece bearing race with capability for rotation and linear up and down positioning motion, and two coordinated and controlled laterally-moving infeed axes for roll finishing tooling dies. For finishing of the outer contacting surfaces of the bearing inner races, two suitably contoured power-driven dies are arranged symmetrically on diametrically opposing sides of the workpiece. A dual but asymmetric tooling arrangement employs a suitably contoured power-driven finish tooling die is positioned for the internal roll finishing operation, while a plane cylindrically shaped idling support tooling die is located on the opposing side of the work region. The apparatus includes specialized contoured finishing tooling for bearing inner and outer race ausform finishing utilizing specially contoured cylindrical roll finishing tolling dies to facilitate infeed ausforming of bearing inner and outer races, the structure and mechanism for asymmetric mounting, powered drive and infeeding of the roll finishing die and the idling support die with respect to the bearing outer race.
