475011000 | ROTARY PLANETATING OUTPUT | 7 |
20080274849 | Gear Transmission Unit With Planetary Gears - A planetary type gear transmission unit ( | 11-06-2008 |
20080287240 | Structure of Swing Part of Industrial Robot - An object of the invention is to effectively prevent surface abrasion in an eccentric part | 11-20-2008 |
20090005205 | Power transmission device - A power transmission device is provided to transmit power from an engine to a transmission, including a transmission mechanism, a first clutch, a second clutch, a damper mechanism, and a casing. The transmission mechanism is configured to transmit power with two kinds of rotational speeds that vary in stages. The first clutch is configured to switch rotational speed in the transmission mechanism to decrease the speed ratio. The second clutch is configured to set the rotational speed ratio of the transmission mechanism so that output rotational speed equals input rotational speed, that is, the transmission mechanism is in a fixed state. | 01-01-2009 |
20090325752 | Medium transportation apparatus and image forming apparatus having the same - A medium transportation apparatus is provided with a plurality of medium transportation units; a drive source; a sun gear connected to the drive source; a planetary gear engaging the sun gear for transmitting a drive force to one of the medium transportation units according to a rotational direction of the sun gear; and a rotational load member for applying a rotational load to the planetary gear. The rotational load member is disposed on an outer side relative to a rotational shaft of the planetary gear in a radial direction of a rotational shaft of the sun gear. | 12-31-2009 |
20100227724 | MECHANICAL SYSTEM FOR POWER CHANGE BETWEEN THE INPUT AND OUTPUT THEREOF - The system includes at least two power disc elements mounted for rotation about a central axis, with one power disc element including a peripheral gear portion in a first rim portion thereof, and with the other power disc element including a first peripheral gear portion in a first rim portion facing the first rim portion of the one power disc element. An intermediate gear element has a set of teeth around the outer periphery thereof and is positioned so as to mate with the first peripheral gear portions of both the one power disc element and the other power disc element. At least one power disc assembly which includes an additional power disc element is positioned either before the first power disc element or following the other power disc element and includes a plurality of gears for connection with a prior or successive power disc element. An input drive assembly provides input power to the power system and an output assembly takes power off the power system. | 09-09-2010 |
20120142473 | TRANSMISSION - A transmission, comprising a rotary shaft ( | 06-07-2012 |
20120329595 | MANIPULATOR FOR COATING APPLICATION - A coating system includes a coating source and a planetary manipulator assembly that includes a first driveshaft capable of receiving rotational input, a sun gear rotationally fixed to the first driveshaft, a planetary gear engaged with the sun gear, a second driveshaft rotationally fixed to the planetary gear such that torque is transmitted from the sun gear to the planetary gear, a support shaft operatively engaged with the second driveshaft, a carrier body supporting the planetary gear relative to the sun gear, a third driveshaft capable of receiving rotational input, and a drive gear rotationally fixed to the third driveshaft. The support shaft is arranged substantially perpendicular to the second driveshaft. The carrier body is rotatable by the drive gear about a common axis with the sun gear, and rotation of the carrier body rotates the planetary gear and the second driveshaft about the sun gear. | 12-27-2012 |
