| 20090056488 | SPIRAL-TOOTHED GEAR WHEEL FOR RACK AND PINION STEERING - A spiral-toothed gear wheel for a rack and pinion steering. The spiral-toothed gear wheel includes a pinion, which meshes on the power take-off side with a toothed rack, and a spiral-toothed gear, which is arranged on the pinion on the drive side in such a way that they rotate in unison, and on which a torque caused by a steering power or/and steering assist power acts. The spiral-toothed gear is designed as a built-up gear and includes a gear rim, which is arranged, relative to the axial direction of the gear or of the pinion thereof, between two flanges. The gear rim is pushed over a hub formed at one of the flanges and is fitted together with the flanges in a positive-locking manner. One of the flanges, namely, the flange having the hub for the gear rim, is made in one piece with the pinion. | 03-05-2009 |

| 20090199667 | MODULAR POWER ACTUATOR - A power actuator assembly includes a torque transmission device, a motor mounted to the torque transmission device extending along a motor axis, and a screw coupled to the torque transmission device and extending along a screw axis. An adjustment mechanism interconnects the screw and the torque transmission device and permits selective rotational adjustment between the adjustment mechanism and the torque transmission device to rotate the motor relative to the torque transmission device. A connecting device releasably interconnects the adjustment mechanism to the torque transmission device to permit repeated re-positioning of the motor relative to the torque transmission device. | 08-13-2009 |

| 20080210037 | Gear - A helical gear having helical tooth portions of the helical gear being worked by a punch and a die having a land of a smaller distance between opposed working surfaces formed to be inclined than that of other portion, formed on predetermined portions in tooth directions of respective opposed working surfaces thereon, in which worked surfaces on both side of the helical tooth portions on the helical gear as a work are ironed by the land in response to the helical tooth portions passing through the land when the work is forged by the punch. | 09-04-2008 |
| 20090241711 | HELICAL GEAR AND METHOD OF MANUFACTURING THE SAME - A method of manufacturing a helical gear, includes a gear cutting process for forming a roughly-processed gear by applying a gear cutting to an outer circumferential surface of a blank, and a tooth surface forming process for forming a tooth surface by pressing a rolling die against a roughly-processed tooth surface of the roughly-processed gear, wherein a length of a portion of the roughly-processed tooth surface, to which a plastic deformation is applied by the rolling die, in a face width direction is formed to be shorter than a length of a face width of the roughly-processed tooth surface. | 10-01-2009 |
| 20090282939 | SPIRAL-TOOTHED GEAR - A spiral-toothed gear is provided with a toothed ring ( | 11-19-2009 |
| 20100005915 | IRREVERSIBLE TRANSMISSION DEVICE - The invention relates to a geared, irreversible motion transmitting device comprising a massive casing supporting an input means and an output means, one end of the input means being fitted with a pinion whereas one end of the output means is fitted with a gear wheel, said pinion and said gear wheel constituting a gear system. Said gearwheel and pinion are designed in a manner that, in operation, pinion rotation generates an effective force acting a distance off the center (C | 01-14-2010 |
| 20110017005 | REDUCED FRICTION RING AND PINION GEAR SET - A ring and pinion gear set comprises a ring gear and a pinion gear. The pinion gear has a plurality of rolling elements. The ring gear has a plurality of mating grooves. The plurality of rolling elements of the pinion gear is adapted to interact with the plurality of mating grooves of the ring gear. | 01-27-2011 |
| 20150377337 | Power Transmission Device - A power transmission device, including a transmission, a case member, a bearing, a counter drive gear that is coupled to an output member of the transmission, that is rotatably supported by the case member via the bearing, and that is formed by a helical gear, and a counter driven gear that meshes with the counter drive gear so that a resultant force of a radially inward force and a force in one direction in an axial direction is applied to the counter drive gear during forward traveling of a vehicle. | 12-31-2015 |
