Patent number: 8351831Abstract: An displacement correcting device is provided and includes: a rotation supporting member having a rotation shaft and rotating to support the endless belt-shaped member; a shaft supporting frame supporting a one-end supporting portion of the rotation shaft movably relative to an opposite-end supporting portion and supporting one end of the rotation shaft to be tilted about the other end; and a shaft displacing member having a rotation center disposed closer to one end portion in the axial direction than a rotation shaft supporting body and intersected by the axial direction and a rotation shaft contact portion contacting with the one end of the rotation shaft. The shaft displacing member allows the rotation shaft contact portion to rotate about the rotation center to tilt the rotation shaft when a movement sensing member detects the movement of the endless belt-shaped member to the one end of the rotation shaft.Type: GrantFiled: October 7, 2009Date of Patent: January 8, 2013Assignee: Fuji Xerox Co., Ltd.Inventors: Satoru Hori, Naohisa Fujita

Publication number: 20080058139Abstract: An automated adjustment system is provided for positioning a speed reduction belt assembly to receive an elongated wood article exiting a processing machine. The speed reduction belt assembly has opposite first and second ends. The automated adjustment system includes a horizontal adjustment mechanism operable to adjust an angle of the speed reduction belt assembly in a horizontal plane. The automated adjustment system also includes a vertical adjustment mechanism operable to adjust the height of one of the first and second ends of the belt assembly relative to the other of the first and second ends of the belt assembly, thereby adjusting an inclination of the belt assembly. The automated adjustment system further includes a control unit in communication with the horizontal and vertical adjustment mechanisms for sending control signals thereto. The control signals determine the angle and inclination of the belt assembly.Type: ApplicationFiled: August 31, 2006Publication date: March 6, 2008Applicant: LES PRODUITS GILBERT INC.Inventors: Sylvain Gilbert, Daniel Pare

Patent number: 7252610Abstract: In a belt drive system 20 for transmitting torque at a crankshaft 11 of an automotive engine 10 to a supercharger (engine accessory) 130a, an output pulley unit 40 formed of a first flat pulley 50 and a second flat pulley 60 is coupled to the rotational shaft 131a of the supercharger 130a. A flat belt 70 entrained between the output pulley unit 40 and the crank pulley 30 of the crankshaft 11 is shifted from the first flat pulley 50 to the second flat pulley 60 or vice versa by a speed ratio selector 80. The rotational shaft 131a can thereby be driven into rotation with the switching between a high speed ratio during acceleration and a low speed ratio during constant speed cruise. As a result, the supercharger 130a can bring out its capability into full play without using parts involving increases in weight, cost and power consumption, such as a solenoid-operated clutch, and concurrently suppress the deterioration of fuel economy.Type: GrantFiled: June 2, 2004Date of Patent: August 7, 2007Assignee: Bando Chemical Industries, Ltd.Inventor: Hirofumi Miyata

Patent number: 7237638Abstract: A belt continuously variable transmission apparatus having a case which includes a power transmission case (which is part of a crankcase of an engine), a power transmission case cover, and an actuator cover assembled forwardly of the power transmission case cover (displaced forwardly on a vehicle body). The actuator cover is formed as a separate member from the power transmission case cover, and supports a motor for driving a movable part of a driving pulley. In addition, the actuator cover covers a gear system. The actuator cover is integrated with a cover of the water pump. The resulting configuration improves the assembling of the actuator cover of the belt continuously variable transmission apparatus.Type: GrantFiled: August 27, 2004Date of Patent: July 3, 2007Assignee: Honda Motor Co., Ltd.Inventors: Hideo Ishikawa, Kenji Oki, Michio Asumi, Fuminori Kamemizu, Hirokazu Komuro, Junichi Sakamoto

Patent number: 5273493Abstract: A tracking device for endless belts moves on a pair of rollers--a driving roller (RM) and a tension roller (1)--especially for an emery cloth belt (TS) moving on the cantilevered rollers (1, RM) of a belt sander (S) for wooden floors. The tension roller (1) is formed in two parts: a minor portion (3), close to a support (5) of the roller shaft (2), mounted--rotatable but not inclinable in respect of said shaft--onto an eccentric rotary sleeve (11), its part closest to the support (5) being of frustoconical shape; and a major portion (4), mounted revolving on a bush (12) coaxial to the roller shaft (2) and inclinable on a ball joint (13) but not rotatable in respect of the shaft. A unilateral contact ball constraint (15) is moreover provided between the sleeve (11) and the bush (12), and at least one spring (16) is provided to cause the inclination of the bush (12) in respect of the roller shaft ( 2) in the direction allowed by the constraint (15).Type: GrantFiled: April 29, 1992Date of Patent: December 28, 1993Assignee: Unibase S.p.A.Inventor: Alberto Felici

Patent number: 5236397Abstract: A belt tension adjustment mechanism having a pivoting pulley support plate adapted to cooperate with a pivoting ratchet plate. The pulley support plate directly or indirectly anchors a belt to be tensioned. A tension spring is associated with the ratchet plate to bias the ratchet plate towards a position of increased belt tension. The ratchet plate includes a teeth and pawl arrangement for preventing the ratchet plate from spontaneous rotation to a position of reduced belt tension.Type: GrantFiled: May 3, 1991Date of Patent: August 17, 1993Assignee: Rover Mowers LimitedInventor: Douglas F. Green

Patent number: 5234382Abstract: An apparatus for limiting deviation of an endless belt/belt sleeve from a desired rotational path. The apparatus has first and second rollers each having a rotational axis and cooperatively supporting an endless belt/belt sleeve trained therearound for rotational movement in a predetermined path. A first member is mounted on one of the first and second rollers for movement axially relative to the one of the first and second rollers. A blocking structure defines a shoulder for engagement with an edge of an endless belt/belt sleeve trained around the first and second rollers to limit movement of an endless belt trained around the first and second rollers in a first axial direction relative to the one of the first and second rollers.Type: GrantFiled: November 26, 1991Date of Patent: August 10, 1993Assignee: Mitsuboshi Belting Ltd.Inventors: Misao Fukuda, Yoshihiro Hayami, Toshihiro Ueda
