  • Patent number: 9556933
    Abstract: Provided is an eccentric oscillation gear device including: a crank shaft having eccentric portions; oscillation gears having insertion holes into which the eccentric portions are inserted; an outer cylinder; and a carrier. The outer cylinder and the carrier concentrically rotate relative to each other by the oscillation of the oscillation gears due to the rotation of the crank shaft. The eccentric oscillation gear device includes a storage unit which stores at least one type of information out of: information on a parameter that originates from a processing error and influences rotation angle characteristics; information on a parameter that changes depending on temperature and influences rotation angle characteristics; and information on a parameter that influences time-dependent change characteristics and influences rotation angle characteristics.

  • Patent number: 9074116
    Abstract: Disclosed is a fluororubber composition comprising (A) 100 parts by weight of a peroxide-crosslinkable fluororubber, (B) 1 to 15 parts by weight of ZnO, (C) at least one of a basic metal hydroxide and a metal oxide other than ZnO at a weight ratio of 0.5 or more with respect to the weight of ZnO, and (D) 0.5 to 10 parts by weight of an organic peroxide. When used for contact with biodiesel fuel, the peroxide-crosslinkable fluororubber composition effectively prevents material degradation shown in BDF while maintaining excellent compression set characteristics due to the addition of ZnO, as in conventional peroxide-crosslinkable fluororubbers, and therefore can be suitably used as, for example, a vulcanization molding material for sealing materials.

  • Patent number: 8444520
    Abstract: A gear device has an outer cylinder fixed to a first mating member and a crankshaft inside the outer cylinder. An external gear is mounted to an eccentric portion of the crankshaft and meshes with internal teeth of the outer cylinder. A carrier is fixed to a second mating member. Rocking rotation of the external gear rotates the carrier coaxially to the outer cylinder. A cylindrical body is inserted in an axial through-hole of the carrier. The carrier has a first portion on one end of the cylindrical body and a second portion on an axially intermediate portion of the cylindrical body. The other end of the cylindrical body extends toward a corresponding mating member while protruding axially beyond the second portion. An outer diameter of remaining portions of the cylindrical body do not exceed an outermost diameter of the portion on which the first and second portions are fit.
