摘要： PROBLEM TO BE SOLVED: To provide an injection molding resin gear for further enhancing accuracy by reducing a contraction difference between respective parts. SOLUTION: This injection molding resin gear 1 has the rim 6 for forming a tooth 7 on the outer periphery, a hub 4 fitted with a shaft and a web 5 for connecting these rim 6 and hub 4. The thickness t1 of the tooth bottom 15 of the rim 6 is formed thinner than the thickness t2 of the web 5. Side surfaces 8 and 8 of the web 5 form annular peripheral directional ribs 10, 11 and 12 projecting in concentrically circular shape to the rim 6 and the hub 4. The relationship between the thickness t1 of the tooth bottom 15 of the rim 6, the thickness t2 of the web 5 and the thickness t3 of the peripheral directional ribs 12 is formed so as to become t1 ≤ t3 COPYRIGHT: (C)2004,JPO

摘要： PROBLEM TO BE SOLVED: To provide a highly accurate and rigid injection molded resin bevel gear for meeting the demands of precise instrument suppliers by scheming a gear structure. SOLUTION: A rimmed portion 13 of a tooth part 5 has almost the same thickness along a tooth bottom 14 and almost the same thickness as a web 4. The radially outward end of the web 4 is connected to the side of an inner end 6a of the rimmed portion 13. A portion out of the rimmed portion 13, ranging from a tooth part connecting portion 12 of the web 4 close to the side of an outer end 6b, is connected to the outer peripheral face of a boss 3 with a plurality of first radial ribs 16. A portion out of the rimmed portion 13, ranging from the tooth part connecting portion of the web 4 close to a tooth-cross-direction central portion 10, is connected to the radially outward end of a second radial rib 20. The first and second radial ribs 16, 20 are formed thinner than the web 4 and the rimmed portion 13 so that the flow of molten resin is guided in priority from the web 4 to the tooth part 5 during injection molding.

摘要： PROBLEM TO BE SOLVED: To provide a new gear having superior durability, heat resistance and dimensional stability in comparison with a conventional polyamide resin made wheel, with a reduction gear using the same and with an electric power steering device using the reduction gear. SOLUTION: In a gear, a gear body having a tooth face is formed by a blend polymer or a copolymer of PA66 and PA6 as a composite resin in which a parts having molecular structures of PA 66 and of PA6 are contained in the weight ratio of PA66/PA6 = 99.9/0.1 to 95.0/5.0. In a reduction gear 50, the gear is employed as a worm wheel 12 (a large gear). The electric power steering device decelerates the output of an electric motor M for steering assistance through the medium of the reduction gear 50 so as to be transmitted to a steering mechanism.

摘要： PROBLEM TO BE SOLVED: To effectively suppress the occurrence of a weldline, to arrange the orientation properties of the reinforcing fiber-containing resin in a web over the whole periphery of the web, to uniformize the flow speed of a resin in a diametric direction before the flow of the resin arrives at a rim not only to enhance the strength of the web but also to enhance molding precision even in a case that an injection-molded resin gear (injection-molded resin rotary body) is molded using a pinpoint gate. SOLUTION: When the resin injected from the pinpoint gate 13 flows through a cavity 2 outward in the diametric direction of the cavity, the flow speed of the resin is uniformized by the parts of resin flow speed adjusting grooves 11 and further uniformized when the resin passed through the part of the resin flow speed adjusting grooves 11 passes through the part of a peripheral direction groove 12 on an outer peripheral side. Accordingly, the flow speed of the resin is uniformized in the web 6 before the resin arrives at the rim 7 having teeth 8 formed thereto on the outer peripheral side thereof.
