Patent number: 8366097Abstract: A clutch transmission mechanism of a printing device includes a power input shaft, a power input gear, a gear-shifting arm, a first gear-shifting module and a second gear-shifting module. In the cooperation of these components and modules, the printing device can be operated in a first gear-shifting mode or a second first gear-shifting mode. When the printing device can be operated in a first gear-shifting mode or a second first gear-shifting mode, the clutch transmission mechanism coaxially transmits the driving force. As such, the stability of transmitting the driving force is enhanced.Type: GrantFiled: June 21, 2010Date of Patent: February 5, 2013Assignee: Primax Electronics Ltd.Inventors: Tung-Wen Tu, Jian Zeng, Jian-Gju Yu

Patent number: 8082817Abstract: A power transmission mechanism having a dog clutch for freely connecting and disconnecting power transmission between a first rotor and a second rotor on a common rotational shaft. The dog clutch has a plurality of dog jaws in one of the rotors and has, in the other rotor, a plurality of recess portions or other dog jaws to which the former dog jaws can be engaged. Tapered surfaces are formed at an end face of each of the former dog jaws in the axial direction and each of wall surface portions formed between the recess portions or an end face of each of the latter dog jaws.Type: GrantFiled: March 10, 2009Date of Patent: December 27, 2011Assignee: Kawasaki Jukogyo Kabushiki KaishaInventors: Shuhei Takahara, Shigeru Nishimura

Patent number: 8002097Abstract: A clutch mechanism of an outboard motor includes a forward gear and a reverse gear that are always driven in opposite directions by a drive shaft driven by a drive system, and a dog gear disposed around the output shaft. The forward gear, the reverse gear, and the dog gear are provided with a plurality of engaging projections and engaging recesses that can be engaged with each other, with the dog gear being engaged with either the forward gear or with the reverse gear by forceably moving the dog gear toward one side in the axial direction. A drive shaft has a drive gear and is driven by the drive system generating a maximum output power of about 300 ps or more, the forward gear and the reverse gear have input gears respectively which are always engaged with the drive gear, and the engaging projections and the engaging recesses are located radially inside of the input gears and disposed at least seven in a row along a circumference thereof.Type: GrantFiled: January 31, 2008Date of Patent: August 23, 2011Assignee: Yamaha Hatsudoki Kabushiki KaishaInventor: Haruhiko Tsurumi

Patent number: 7810625Abstract: A sintered clutch ring (1) is described, comprising a rim of clutch teeth (2) which comprise wedge-like face surfaces (3, 4) intersecting in an axial plane and flanks (5) sloping downwardly under an angle of inclination from the tooth back (6) against the tooth root, with the flanks (5) being relieved starting from a re-entrant, axially normal shoulder (7). In order to provide advantageous conditions for press forming the flank reliefs it is proposed that the planes of intersection between the wedge-like face surfaces (3, 4) extend outside of the center of the teeth and that the mutually axially offset shoulders (7) of the two flanks (5) of the clutch teeth (2) separate the relieved flanks (5) from a paraxial flank portion (8) which is substantially triangular and is adjacent to the face surfaces (3, 4).Type: GrantFiled: November 14, 2005Date of Patent: October 12, 2010Assignee: Miba Sinter Austria GmbHInventors: Günter Nelböck, Alexander Weiermair, Franz Heitzinger

Patent number: 7413067Abstract: A first dog clutch member is coupled with a rotation transmitting member rotatably mounted on a power transmission shaft with a relative rotation clearance ?. A second dog clutch member is slidably mounted on the power transmission shaft to be engageable/disengageable with/from the first dog clutch member. A damper spring is interposed between the rotation transmitting member and the first dog clutch member. First dog teeth and second dog teeth, which are engaged/disengaged with/from each other by an axial displacement of the second dog clutch member, are formed in the first dog clutch member and the second dog clutch member, respectively. A chamfer is made in each end portion of the respective first dog teeth and each end portion of the respective second dog teeth, which are opposed to each other, so as to guide the second dog teeth to a position to engage with the first dog teeth.Type: GrantFiled: January 23, 2006Date of Patent: August 19, 2008Assignee: Honda Motor Co., Ltd.Inventors: Yoshiaki Tsukada, Kazuhiko Nakamura
