| A gear roll-forming apparatus includes: a pinion die that is substantially the same in configuration and size as a bevel pinion; a pinion die holder for supporting the pinion die so as to allow rotation of the pinion die about a first axis of the pinion die while preventing axial movement B of the pinion die in an axial direction thereof from a small-diameter side toward a large-diameter side thereof, a gear die that is substantially the same in configuration and size as a bevel gear and meshes with the pinion die; and a pressing member for bringing a bevel gear blank into press contact with the pinion die, the bevel gear blank being arranged so as to sandwich the pinion die in cooperation with the gear die. By relatively rotating the gear die and the pinion die holder about a second axis of the gear die, the teeth of the pinion die are rolled with respect to the bevel gear blank. | ||||||

| Teeth are ring rolled in a closed die formed between upper and lower clamping elements in a starting workpiece that is a pretreated blank whose shape outside a region to be deformed by upper and lower profiled tools already corresponds generally to a desired finished shape. Prior to rolling the region to be deformed is heated and the upper profiled tool together with the upper synchronously rotating clamping element form a closed cavity around the heated region to be deformed of the workpiece with the upper tool angled relative to the workpiece. The tools and elements are rotated while engaging the workpiece and deformation takes place between the rotating tools. The angled upper tool is advanced along its symmetry line into the workpiece as the workpiece is deformed. The upper clamping element is axially retracted opposite to the upper tool and away from the workpiece during the rolling process along the symmetry line of the upper profiled tool as the workpiece is deformed. | ||||||

| The invention relates to a process for ring rolling the teeth of bevel gears, preferably hypoid-toothed bevel gears, in a closed die, in which use is made of a pretreated blank of which the outline outside the shaping region of the profiled tools already substantially corresponds to the finished outline, the outline to the shaped is heated before rolling, the shaped tool together with at least one closing device rotating with it forms a closed space with respect to the heated outline of the tool, shaping is performed between two rotating tools and the bevelled upper tool is set in the direction of its line of symmetry. The invention proposes that the closing device is axially shifted along the line of symmetry of the upper shaped tool during the rolling process. The tooling of the invention for implementing the process consists of two rotating tools which are inclined towards each other in accordance with the outlines of the bevel gear to be produced. The upper shaped tool is axially adjustable towards its line of symmetry and the outline of the workpiece to be shaped is arranged during the rolling process in a closed space formed by the upper shaped tool and at least one closing device rotating with it. The closing device (4, 5) consists of an inner (4) and an outer (5) band which can be moved in the adjusting direction in relation to the upper shaped tool (3) during the rolling process. | ||||||

| PURPOSE:To roll a tapered surface with a simple mechanism by immovably holding a work having the tapered surface on the outside periphery in the axial direction and rotationally pressing plural bevel rolling dies or bevel rolling die pair rotating in the directions opposite from each other at the center line perpendicular to the axial center. CONSTITUTION:The work 22 having the tapered surface 16 on the outside periphery is attached by a holder 20 and is freely rotatably held in such a manner that the work cannot move in the large-diameter direction of the tapered surface at the axial center. The plural bevel rolling dies 64, 66 are pressed to the tapered surface 16 to roll said surface or a pair of the bevel rolling dies 30, 32 having rolling parts 38 rotating in the directions opposite from each other at the common center line XY perpendicular to the axial center of the work 22 are rotationally pressed to the tapered surface 16 of the work 22, by which said surface is rolled. The rolling of the tapered surface of the work is easily executed by the simple mechanism. The rolling may also be executed by successively providing a notch, a lead part, parallel tooth part and relief tooth part to the objective rolling part 38 of the dies 30, 32 and rotating and quickly stopping the dies 30, 32. | ||||||

| PURPOSE:To improve operability and reduce cost either facilitating or omitting an after process by setting a ring like material for insertion to a concentric central mandrel of a lower die provided with an annular tooth part, and performing an oscillation forging by means of a upper die and thereby improving a concentricity of a tooth part of a bevel gear and the shaft hole. CONSTITUTION:An annular material 2 is set for insertion to a concentric central mandrel 3 of a lower die with an annular tooth part 1a. An oscillation forging is performed by the draft of an upper die 7. An error on the concentricity on the tooth part 1a of a forged bevel gear 2' and the shaft hole is eliminated. Thus, a working in a succeeding stage is facilitated, and depending on a case a succeeding finishing stage may be omitted. And a productivity of the bevel gear is increased and the cost price is reduced. | ||||||

| A method for hot rolling of bevel gears by infeeding a rotating gear roll die having a synchronizing member into a rotating work gear having a synchronizing member. First, the teeth of the synchronizing members are brought into engagement, and then rough forming of teeth on the work gear takes place under the action of the teeth of the gear rolling die, wherein the synchronizing member of the work gear is acting as the driving member, and finish rolling of the rolled teeth of the work gear takes place, with the rotating gear rolling die acting as the driving member.An apparatus for carrying out the above method for hot rolling of bevel gears includes a work gear spindle having its power rotation drive and a gear rolling die spindle having power drives for its rotation and axial movement, the spindles being installed in the bed at an angle with respect to each other. There is also provided a power distribution unit connected to the power drives for rotating the gear rolling die spindle and work gear spindle, respectively. | ||||||
