| 475176000 | Gear has plural circumferential tooth sets | 10 |
| 20090298636 | Gear-type reduction unit, particulary for rotary platforms for sun-following devices - A gear-type reduction unit, particularly for rotary platforms for sun-following devices, which comprises two main components, associated for rotation with respect to each other about a main rotation axis, a driving shaft, supported for rotation about the main axis, by a first one of the main components, a transmission element provided with two pinions, which are jointly connected and have an axis that is eccentric with respect to the main axis, a connecting member for mutual eccentric rotation of the transmission element with respect to the driving shaft, a first ring gear and a second ring gear with internal sets of teeth, which are jointly connected respectively to the first and second of the main components and mesh respectively with the first and the second of the pinions, and a play recovery device to take up slack between the pinions and the ring gears. | 12-03-2009 |
| 20140171251 | COAXIALLY ARRANGED REDUCTION GEAR ASSEMBLY - A reduction gear assembly integrates a stationary section having a stationary internal gear configuration, an output section having an output internal gear configuration, an input shaft and planetary carrier comprising an input shaft having a shaft rotational axis and a planetary gear cam having a planetary gear rotational axis, wherein the shaft axis and cam axis are offset. A planetary gear comprising a planet wheel first stage and a planet wheel second stage is rotationally assembled to the planetary gear cam. The first stage planet wheel engages with the stationary gear. The second stage planet wheel engages with the output gear. Rotation of the input shaft rotates the planetary gear about a circular path. Engagement between the first stage and the stationary gear rotates the planetary gear. Second stage teeth engage with the output gear. Difference in first stage and second stage teeth counts causes rotation of the output section. | 06-19-2014 |
| 475177000 | Internal and external tooth sets | 8 |
| 20090192004 | Oscillating inner gearing planetary gear system - An oscillating inner gearing planetary gear system is provided which does not need to occupy a large space even in a state where a driving source is joined. In particular, the axial length thereof can be shortened, and a large diameter hollow shaft therethrough can be formed. The oscillating inner gearing planetary gear system ( | 07-30-2009 |
| 20130231211 | TRANSMISSION WITH RADIALLY STACKED GEAR SETS INCLUDING ANNULAR GEAR - A transmission includes a first gear set with a first sun gear member rotatable about a first axis of rotation, a first carrier member, and a first ring gear member radially outward of and concentric with the first sun gear member. The first ring gear member has a radially inward-facing surface with inner teeth and a radially outward-facing surface with outer teeth. A second gear set has a second carrier member, and a second ring gear member radially outward of and concentric with the first ring gear member. The second ring gear member has a radially inward-facing surface with inner teeth. A first annular gear has a radially inward-facing surface with inner teeth and a radially outward-facing surface with outer teeth. The first annular gear is rotatable about a second axis of rotation and meshes with the first ring gear member. | 09-05-2013 |
| 20130231212 | TRANSMISSION WITH DOUBLE-SUN, ONE RING, AND DOUBLE-ANNULAR GEAR COPLANAR GEAR SET - A transmission includes a first gear set with a first sun gear member rotatable about a first axis of rotation, a second sun gear member rotatable about the first axis of rotation, a carrier member, and a ring gear member radially outward of and concentric with the first sun gear member. A first annular gear meshes with the first sun gear member, and a second annular gear meshes with the first annular gear, the second sun gear member, and with the ring gear member. The first annular gear is rotatable about a second axis of rotation and the second annular gear is rotatable about a third axis or rotation. | 09-05-2013 |
| 20130231213 | TRANSMISSION WITH DOUBLE-SUN, ANNULAR GEAR, AND OUTER GEAR COPLANAR GEAR SET - A transmission includes a coplanar gear set with a first sun gear member rotatable about a first axis of rotation, a second sun gear member rotatable about the first axis of rotation, a carrier member, and an outer gear radially outward of and concentric with the first sun gear member. A first annular gear meshes with the first sun gear member, and the outer gear meshes with the first annular gear and with the second sun gear member. The first annular gear is rotatable about a second axis of rotation and the outer gear is rotatable about a third axis or rotation. | 09-05-2013 |
| 20130231214 | TRANSMISSION WITH DOUBLE-ANNULAR GEAR COPLANAR GEAR SET - A transmission includes a first gear set with a sun gear member rotatable about a first axis of rotation, a carrier member, and a ring gear member radially outward of and concentric with the first sun gear member. A first annular gear meshes with the sun gear member, and a second annular gear meshes with the first annular gear and with the ring gear member. The first annular gear is rotatable about a second axis of rotation and the second annular gear is rotatable about a third axis or rotation. | 09-05-2013 |
| 20140162827 | SEAT FITTING FOR A MOTOR VEHICLE SEAT - A motor vehicle seat fitting includes a fitting top part with a ring gear ( | 06-12-2014 |
| 20160003325 | DRIVING DEVICE - A driving device is provided with a first supporting member disposed in one direction along a rotation axis of a rotated member, and a second supporting member disposed in the other direction. The first supporting member is provided with a first case and a first supporting shaft. The first supporting shaft passes through a first through hole of the first case. The second supporting member is provided with a second case and a second supporting shaft. The second supporting shaft passes through a second through hole of the second case. Only one first bearing is disposed between the first case and the first supporting shaft. Only one second bearing is disposed between the second case and the second supporting shaft. | 01-07-2016 |
