Patent number: 10113596Abstract: A power transmission device that transmits a rotational driving force outputted from a driving source to a target device to be driven includes: a driving rotor rotated by the rotational driving force; a driven rotor that rotates with a rotary shaft of the target device; and a connection member. The connection member has a plate shape extending perpendicular to the rotary shaft. The connection member is connected at least one of the driving rotor and the driven rotor, and is capable of connecting the driving rotor and the driven rotor to each other. The connection member has a through hole, and the driven rotor has an overlapping portion disposed overlapping with the through hole when viewed in the axial direction of the rotary shaft.Type: GrantFiled: March 24, 2015Date of Patent: October 30, 2018Assignee: DENSO CORPORATIONInventors: Hiroshi Nakajima, Youhei Kushida, Kiyomi Okuda, Akira Kishibuchi, Toshihiro Hayashi

Patent number: 9958043Abstract: A power transmission device includes a pulley constituting a driving-side rotor, an inner hub, a washer and a limiter which constitute a driven-side rotor, and a plate configured as a linking elastic member that connects the driving-side rotor and the driven-side rotor. A flat spring that elastically deforms in a direction along a rotation shaft is adopted as the plate. A distance in an axial direction between a pulley-side attachment portion of the plate which is attached to the pulley and a hub-side attachment portion of the plate which is attached to the inner hub is adjusted to fall within a predetermined standard range by interposing a shim as an adjustment member between the plate and the pulley.Type: GrantFiled: March 28, 2014Date of Patent: May 1, 2018Assignee: DENSO CORPORATIONInventors: Yousuke Nakamura, Manabu Saiki, Kiyomi Okuda

Patent number: 6609980Abstract: In a flexible joint having a first rotating body connected to a shaft of an engine, a second rotating body coaxially connected to the first rotating body via a first rubber damper, and a third rotating body whose outer circumference is coaxially coupled with the second rotating body via a second rubber damper and whose center axis is coaxially connected to a shaft of a compressor, the second rotating body is rotatably held by a front housing of the compressor. Accordingly, eccentric load acting on the joint according to the rotation thereof is received by the housing of the compressor so that the shaft of the compressor receives lower bending moment. Further, as the first and second rubber dampers are used, a composite elastic coefficient thereof is smaller so that torque fluctuation applied to the joint is adequately absorbed.Type: GrantFiled: October 5, 2001Date of Patent: August 26, 2003Assignee: Denso CorporationInventors: Yasuo Tabuchi, Masao Nakano, Junichi Ohguchi, Kiyomi Okuda, Manabu Saiki

Patent number: 5899811Abstract: A device for transmitting rotational power from an automobile engine to a compressor for use in an automobile air conditioning system is provided. The device includes a pulley, which is supported on a housing of the compressor for rotation, for receiving rotational power from the automobile engine, and a hub connected to the drive shaft. At least one elastic member which defines outer and inner peripheral surfaces is provided. A first holder member is provided along the outer periphery of the hub for holding the elastic member. A second holder member, which is connected to the pulley, is provided for holding the elastic member. The first and second holder members radially cooperate with each other to circumferentially hold the elastic member during normal operation to transmit the rotation. The first and second holder members are disconnected by deformation of the at least one elastic member when a relative rotation between the pulley and drive shaft occurs.Type: GrantFiled: February 27, 1997Date of Patent: May 4, 1999Assignee: Denso CorporationInventors: Akira Kishibuchi, Kiyomi Okuda, Yasuo Takahara

Patent number: 5683299Abstract: A device for transmitting rotational power from a rotational power source to a rotational driven member is provided with a first rotating member provided for rotation in a rotational direction about an axis, and a second rotating member provided for rotation about the same axis. The first rotating member is connected to the rotational power source and the second rotating member is connected to the rotational driven member. An mechanism for rotationally connecting the first and second rotating member is provided. The connecting mechanism is provided with at least one elastic member made of a rubber material; a first holder member for holding the elastic member from the radially outside of the elastic member; and a second holder member for holding the elastic member from the radially inside of the elastic member. The first and second holder members are mounted to one of the first and second rotating members.Type: GrantFiled: September 13, 1995Date of Patent: November 4, 1997Assignee: Nippondenso Co., Ltd.Inventors: Akira Kishibuchi, Kiyomi Okuda, Junichi Toyama, Yasuo Takahara, Kazuo Oyobe
