摘要： A manufacturing method and apparatus for gears for a speed change device. The gears having a large end and a small end forming a reverse-tapered tooth part on an outer circumference thereof, spline teeth of an intermediate material having the small end provided in a rim of the large end thereof, a plurality of dies having a radial shape and an inclination angle to a gear axial line and slidably holding to an inclined axial line on a holding member are slid from outside of the radiation direction toward the center by a pushing cam mechanism, thereby pushing the reverse-tapered blade part formed at the leading end of the die, the spline teeth are formed in the reverse-tapered tooth part, and the die is slid by an extracting mechanism from the center of the radiation direction toward the outside along the inclined axial line.

摘要： A raw material of aluminum base alloy is extruded and formed by using a forming pattern comprising an upper pattern having plural through-holes for supplying the raw material into diaphragms of equal angles on the circumference and circular cylindrical protrusions positioned in the center of plural through-holes so as to be surrounded by plural through-holes at the exit side of the through-holes, and a lower pattern positioned in the concave portions commonly penetrating at the exit of the plural through-holes of the upper pattern, having through-holes for inserting the protrusions of circular circumference of the upper pattern by providing a tube forming gap, positioned in the center of concave portions of the concave portions in the circular columnar shape of the upper pattern.

摘要： Provided is a gear material that is for a differential ring gear or the like, and that has a relatively large shape and has spur gear teeth or helical gear teeth at an outer periphery thereof, and with which the yield of a final product is improved, the operating cost of gear cutting by a hobbing machine is reduced, and the rate of cutting is dramatically increased to reduce a machining time, whereby the total manufacturing cost can be reduced. This gear material is in the shape of a ring having an outer diameter of at least 170 mm and an outer peripheral thickness of at least 30 mm, and has, at an outer peripheral surface thereof, spur gear teeth or helical gear teeth with a machining allowance of 0.2 mm to 2.0 mm on either side thereof.
