Abstract: A pressure angle of the worm is set to be greater than a pressure angle of the worm wheel so that a maximum number of meshing teeth becomes smaller than or equal to n (where n is a natural number) with respect to the speed reduction mechanism in which a number of meshing teeth is always n+1 or changed between n+1 and n by rotation under a condition in which the pressure angles of the worm and the worm wheel are the same with respect to each other.

Abstract: A gear assembly that can prevent a reduction in power transmission efficiency and a manufacturing method thereof are provided. The gear assembly comprises a first gear and a second gear. The gear assembly is designed in such a manner that first gear tooth and the second gear tooth are contacted properly to each other in a plane of action when operated in a predetermined condition. A rigidity reducing portion is formed on a first base portion to avoid improper contact in the plane of action when the gear assembly is operated in a different condition.

Abstract: A method for manufacturing a flexible externally toothed gear includes: a first step (ST1) for producing a primary molded article by performing near-net-shape plastic working on a material comprising a nickel-free low-alloy steel having a silicon content of 1.45-1.5 wt %; a second step (ST2) for martempering the primary molded article; a third step (ST3) for producing a secondary molded article from the primary molded article; and a fourth step (ST4) for shot-peening the secondary molded article to change the surface portions of the tooth part and other parts to martensite. A flexible externally toothed gear can be obtained in which the surface hardness is kept within a prescribed range and the fatigue strength and abrasion resistance are high.

Abstract: Plural ejector pins are made to project before a molten resin containing reinforcing fibers is injected into an inside of a cavity through pin point gates in a web forming portion in the inside of the cavity and at positions outside the pin point gates in a radial direction. The ejector pins are retracted from the inside of the cavity after a flow of the molten resin containing reinforcing fibers injected into the inside of the cavity through the pin point gates impinges on the ejector pins and is divided and before a tooth portion forming portion in the inside of the cavity is filled with the molten resin containing reinforcing fibers. Accordingly, weld lines which extend along the radial direction are formed at positions outside the ejector pins in the radial direction, and the molten resin is filled in portions formed after the ejector pins are retracted.
