  • Patent number: 9267594
    Abstract: Mating bevel gears generally include a pinion gear having a body that rotates about an axis and a side gear having a body that rotates about an axis that intersects the axis of the pinion gear. Pinion gear teeth of the pinion gear have a side that defines a curvature with an involute section through which a pitch line extends and a parabolic shape between the pinion gear teeth. Side gear teeth of the side gear have a side that defines a curvature with an involute section through which a pitch line extends and a parabolic shape between the side gear teeth. The curvatures on the pinion and the side gear teeth cooperatively define a controlled relative radius of curvature section except where the involute sections are located. The controlled relative radius of curvature section defines a sum of values of radius of curvature at a point of contact between the curvatures of the pinion gear teeth and the side gear teeth. The sum has a constant or decreasing value.

  • Patent number: 9027427
    Abstract: A method is described for changing gear-ratio by displacing at least one part of the engaging surface of a composite gear (21) and aligning it to the engaging surface of another gear (22), thus permitting a complementary third gear (25) engaged to the engaging surface, to shift from one composite gear to a different composite gear, while being constantly engaged. The method can be employed in a device, which can be used to form a gear-based, continuously engaged, variable transmission. Such a transmission, enhanced by—being combined with a differential assembly and the appropriate gearing, can provide rotational motion at various speeds in one direction and the reverse direction as well as zero motion.

  • Publication number: 20140076083
    Abstract: An integrated member can comprise different members each formed of materials having different mechanical characteristics. A method for manufacturing such an integrated member can comprise an electric resistance welding step in which the first member is press-fit into the second member and the press-fit portion can be electrically energized to achieve the electric resistance welding so as to integrate the first member and the second member. The method can further comprise a carburized layer forming step in which carburizing-quenching and tempering, or carbonitriding-quenching and tempering, is performed on the integrated member obtained in the electric resistance welding step to form carburized layers therein in accordance with the mechanical characteristics of the first member and the second member.

    Abstract: A drivable projection for a toner cartridge drum gear includes an axially extending support portion having a plurality of axially extending edges and an end face. A plurality of substantially spherical engagement portions are supported by the support portion, and each engagement portion defines a center that may be substantially aligned with the end face and/or substantially aligned with a respective one of the plurality of axially extending edges. The engagement portions are configured to receive driving rotatable force from the drive mechanism of a printer.

  • Publication number: 20140043019
    Abstract: An angle sensor for determining a rotation angle of a rotatable body, such as a steering column in a motor vehicle, includes a gear wheel. The orientation of a magnetic field generated by the gearwheel is configured to be detected by a magnetic field sensor. The gear wheel is comprised of a magnetisable material, such as hard ferrite, into which a magnetisation is introduced. The gear wheel is stronger in a central region than in an edge region in which the teeth are arranged. In order to weakly magnetise the edge region, which minimizes a negative influence of the teeth on the homogeneity of the generated magnetic field, the front face of the gear wheel is configured to be magnetized. The magnetisation process advantageously takes place at the same time as an injection moulding process to form the gearwheel. A method is implemented to produce the gear wheel.

  • Publication number: 20140041476
    Abstract: A driving gear includes a shell for fixed connection with a photosensitive roller, a coupling member detachably mounted inside the shell, and a driving member for being driven by a driving shaft located inside a printer. The shell includes two convexities and a rib for engaging two hook pieces and a fitting slot of the coupling member respectively. The coupling member includes a tunnel and a limiting portion located inside the tunnel. The driving member includes a first end portion located between the limiting portion and a bottom portion of the shell, a second end portion extending out of the coupling member, and a protrusion protruding from the first end portion and located in a limiting slot of the coupling member. Therefore, it will be not difficult for the user to install or detach the driving gear to or from the photosensitive roller.

  • Publication number: 20140013888
    Abstract: Balance shaft for a piston engine comprises a bearing journal, on which the balance shaft is supported, a gear section, on which a gear is connected in a rotation-locked manner thereto via a press fit or another shaft-hub-connection, and an unbalanced section having an integrally connected unbalanced mass or an unbalanced mass fastened on this unbalanced section using machine elements or via another shaft-hub connection. The balance shaft can alternately comprise steel or cast iron material in the case of a friction mounting and its bearing journals can alternately be implemented as hardened or also unhardened. If the balance shaft is mounted in roller bearings and if the roller bodies have direct contact with the bearing surface, it is implemented in a suitable steel and the bearing journals are hardened. The gear comprises nodular cast iron and is not hardened.

  • Publication number: 20140007724
    Abstract: Provided is a method for manufacturing a gear wheel, the method including: preparing an insertion unit formed of a steel material having a hollow pipe shape; injection-molding an outer side unit including teeth on an outer circumference; and molding a connection unit having a wheel shape by injecting resin into at least three points between the insertion unit and the outer side unit so as to connect the insertion unit and the outer side unit after arranging the insertion unit on the inner center of the outer side unit. According to the method, removing of an unnecessarily injected portion may be omitted since the resin is injected between the insertion unit and the outer side unit while injection-molding the connection unit. Also, productivity is increased by decreasing a number of defective products generated due to cracks.

    Abstract: A manufacturing method for a toothed member includes a thickened tooth shaping process in which a toothed shape is formed on a side wall portion while making a thickness of the side wall portion larger than a thickness of a bottom surface portion by relatively moving the compression die with respect to the restraint die and the pressure receiving member in the axial direction from the side of the opening end of the cup-shaped raw material toward the bottom surface portion. The manufacturing method being such that the thickened tooth shaping process includes applying a load against the restraint die such that the restraint die restrains the first surface and the second surface.
