Abstract: A driving force transmission device includes a rim having a toothed outer periphery, with bottom lands being formed between respectively adjacent teeth and top lands being formed at teeth crests. Outer ribs are disposed at positions on an inner peripheral surface of the rim corresponding to the bottom lands, whereby there is neither variance in angle speed nor uneven rotation of a member driven by the transmission device. Moreover, the outer ribs are radially offset from inner ribs, whereby tensile forces generated between the outer and inner ribs and caused by material shrinkage cancel each other out and defective molding of teeth crests can be minimized. Accordingly, the radius of an imaginary circle formed by joining the top lands is uniform in a circumferential direction.

Abstract: A hollow rack shaft is produced by forming a plate work piece and has continuous metal flow along the contour of rack teeth surface without being cut. A series of wave-like concave-convex sections is formed on the inner surface of the shaft. Thickness of tooth body and tooth bottom of the rack teeth is adjusted by dimensions of the unevenness. Thereby, stress concentration at each point of the rack shaft is prevented and the shaft is strengthend and lightweightized.

Abstract: Helical or spur gear drive comprising a driven gear and driving gear wherein the driving gear has double crowned teeth defined as (i) an envelope to a family of surfaces generated by a skew or straight rack-cutter having a parabolic tooth profile in normal section and then (ii) as an envelope to a family of tool surfaces that are generated while the tool performs a plunging motion with respect to the driving gear in the direction of the shortest distance between the axes of rotation of the tool and the driving gear and tool plunging motion is varied by a parabolic function, whose variable is displacement of the tool in a direction parallel to the rotational axis of the driving gear. The driven gear has a tooth surface defined as the envelope to a family of surfaces generated by a rack-cutter which surface is parabolic cylinder or a plane. The generated pinion/gear tooth surfaces are in theoretical point contact at every instant and they produce a preselected parabolic function of transmission errors in the process of meshing. The pinion/gear exhibit reduced vibration and noise, reduced shift of bearing contact caused by misalignment, and reduced contact stresses due to convex-concave contact of tooth surfaces.

Abstract: A method for the manufacture of a machine part with external toothing from a circular sheet metal blank. According to this method the blank is fixed between a tool and a tail stock. Subsequently the circumferential edge of the circular sheet metal blank is bent by a first metal working roll towards the side of the tool by an angle of more than 180.degree. to form a curl. This curl is radially flattened with a second metal working roll. Subsequently the flattened curl is pressed against the tool with a gear cutting roll and shaped to form an external tooth system.
