摘要： Multi-chamber furnace for vacuum carburizing and quenching of gears, shafts, rings and similar components has at least two process chambers connected in parallel, with a continuous feeding mechanism for individual workpieces. Those chambers—the first one being a heating chamber, the second being a carburizing chamber and the third one diffusion chamber—are configured in a vertical arrangement, placed in a shared vacuum space with gas-tight division, whereas at the ends of each chamber there are incorporated heating chambers with thermal insulation, with a graphite heating system and stepping feeding mechanism incorporated in the core for the purpose of continuous feeding of individual workpieces. At the ends of those chambers the construction incorporates transport chambers featuring loading and unloading systems X-Y enabling cooperation with individual process chambers through thermal and gas-tight doors installed in chamber ends, while external access to the transport chambers is ensured through loading and unloading locks.

摘要： An object of the present invention is to provide a technique for improving a strength, especially a fatigue strength of a power transmission shaft provided with a serrated portion for torque transmission such as a spline shaft. A power transmission shaft is serration-fitted to an inner joint member of respective constant velocity joints. A drive shaft is provided with a serrated portion as well as a smooth portion having a cylindrical outer circumferential surface. A cut-up portion is formed at the end portion of the serrated portion. When applying an induction hardening to the smooth portion and the serrated portion, a hardening ratio of the smooth portion is set at a different value from that of the serrated portion, and such that a fatigue strength of the smooth portion becomes equal to or greater than that of the serrated portion.

摘要： A method for zone heat treatment of metallic workpiece with a comparatively large cross-section, in which the workpiece is successively passed through a zone of higher temperature in such a way that the temperature of the workpiece initially rises steeply as a function of the displacement in the feed direction, passes through a flat maximum and then falls with a small slope. The method is carried out by passing the workpiece through a heating device equipped with a heating coil and a subsequent insulation body, or alternatively through a furnace. In a special embodiment of the method for obtaining the highest possible temperature gradient, the workpiece is drawn from a water bath and then passed through the heating coil.
