| A traction-drive force transmission mechanism, includes a sun roller rotatable about a first axis and a plurality of shafts. Each is disposed on an adjacent axis inclined relative to the first axis. Planetary rollers are disposed along an outer peripheral surface of the sun roller and are supported respectively by the shaft. A carrier holds each of the shafts in the inclined posture and is adapted to be rotated about the first axis together with the planetary rollers. A pressing member pressingly moves each planetary roller in a direction for reducing a distance to the first axis so as to press each planetary roller against the outer peripheral surface of the sun roller. Thus a driving force can be transmitted to a traction force between the sun roller and each of the planetary rollers. | ||||||

| 170 | Composite planetary device | US10563292 | 2004-12-13 | US20060166781A1 | 2006-07-27 | Kohei Hori |
| A composite planetary speed reduction device (1), wherein gears (11), (12), and (13) and rollers (21), (22), and (23) forming a planetary gear speed reduction mechanism (10) and a planetary roller speed reduction mechanism (20) are integrally rotated around a common rotating center axis, respectively. The radius of the sun roller (21) is larger by Δr1 than the radius r1 of the working pitch circle of the sun gear (11), the radius r21 of the working pitch circle of the planetary gear (12) meshing with the sun gear (11) and the radius r23 of the working pitch circle of the planetary gear (12) meshing with an internal gear (13) are different from each other, and the radius of the planetary roller (22) is smaller by Δr1 than the radius r21 of the working pitch circle of the planetary gear (12). Thus, a slippage ratio s1 between the sun roller (21) and the planetary roller (22) and a slippage ratio s2 between the planetary roller (22) and the ring roller (23) are made equal to each other, and a large output torque can be provided from the planetary roller speed reduction mechanism (20). | ||||||

| A speed change device has an input member rotatable in opposite directions to transmit higher torque as its rotation angle becomes larger, and a variable angle-ratio change mechanism including rollers and teethed wheels that are arranged in parallel to each other. The rollers and teethed wheels are respectively connected to rotate together with each other. The teeth of the wheels have a clearance on a pitch circle between their adjacent teeth so that the clearance is larger than a slip amount of the rollers in a low torque range where the rollers transmit low torque with bypassing the wheels in a normal operation. The wheels are engaged with each other to transmit high torque in a high torque range where the high torque is applied in an exceptional operation and the rollers slip larger than the slip amount in the low torque range. | ||||||

| A hub assembly, which accommodates rotation about an axis with a change in angular velocity, includes a carrier that is attached to a supporting structure, a shaft having a pair of sun rollers located in the carrier, a hub having a pair of rings, each surrounding a different sun roller, and planet rollers arranged in two rows between the sun rollers and the rings. The sun rollers have tapered raceways, as do the rings, and the planet rollers have tapered side faces along which they contact the raceways. The carrier has axles about which the planet rollers rotate, with each axle supporting a roller of each row. The planet rollers bear against each other at beveled end faces such the rollers on each axle back each other. Each roller contains an antifriction bearing which enable it to revolve on its axle and transfer radially and/or axially directed loads to the carrier. The planet roller axles are supported in the carrier such that wheel loads are transferred from the hub to the carrier and then to a supporting structure to which the carrier is mounted such that the wheel loads bypass a central shaft which extends through the hub and carrier. | ||||||
| 173 | Planetary traction drive with multiple inputs | US10778269 | 2004-02-13 | US20040162175A1 | 2004-08-19 | Xiaolan Ai |
| A traction drive has inner and outer rings and drive and idler rollers organized in two rows between the rings, with the drive rollers being in an inner row and the idler rollers being in an outer row. The drive rollers contact the inner ring and the idler rollers contact the outer ring. At least one idler roller exists for every drive roller, with the idler roller and its drive roller being in contact between the two rings. Moreover, each idler roller is offset slightly circumferentially with respect to its drive roller such that the idler roller occupies a convergent space between its drive roller and the outer ring. The drive rollers rotate within an inner carrier, while the idler rollers rotate within an outer carrier and one of the carriers can rotate slightly relative to the other carrier. Each drive roller may be coupled with an electric motor. In one direction of rotation for the drive rollers, the idler rollers that are offset slightly behind the drive rollers are drawn into the convergent spaces between the drive rollers and the outer ring and this increases the contact forces between the rollers and their respective rings and between the rollers themselves. An actuator may be used to effect rotation between the carriers. | ||||||

An output shaft extends from the plate and may or may not be coaxially aligned with the sun roller. The output shaft may be connected via a link to a lever arm on the throttle shaft of the throttle valve, which may be used on an internal combustion engine. | ||||||
| 175 | Eccentric planetary traction drive transmission with a single planetary roller | US10233697 | 2002-09-04 | US06702704B2 | 2004-03-09 | Xiaolan Ai |
| An eccentric planetary traction drive transmission in which a planetary roller is positioned between and in contact with an outer ring member and a sun roller member. Rotation of either the outer ring member or the sun roller member wedges the planetary roller within a convergent gap which squeezes the planetary roller between the outer ring member and the sun roll member. Friction between the planetary roller, the sun roller member, and the outer ring member transmits rotational motion and torque between the outer ring member and the sun roller member. An internal carrier with a plurality of bearings supports the sun roller member within the outer ring member. | ||||||

| A wind driven electrical power generating apparatus includes a rotor rotating by receiving wind force, a gear assembly having an input shaft connected to the rotor, a generator connected to an output shaft of the gear assembly, a sensor for detecting generating capacity of the generator and a controller for varying gear ratio of the gear assembly based on a signal from the sensor. In this construction, the controller controls so that the generator keeps rotating at around the lowest rotational speed within a range of rotational speed, the range being determined so as to include a maximum power operation region of the generator.

| An improved planetary traction drive mechanism for use in actuating a throttle valve assembly. An electric drive motor supports a cup-shaped member defining the outer ring of the mechanism. The drive shaft of the motor extends into the cup-shaped member to define a sun roller and forming an annular space between the sun roller and the outer ring. An output plate is rotatably supported on the drive shaft, and one or more planetary friction rollers disposed in radial compression between the outer ring and the sun roller are mounted on the plate. An output shaft extends from the plate and may or may not be coaxially aligned with the sun roller. The output shaft may be connected via a link to a lever arm on the throttle shaft of the throttle valve, which may be used on an internal combustion engine. The planetary rollers are formed from a resilient composite polymer which is mildly compressible, has a suitably high coefficient of sliding friction against metal, a low coefficient of wear, and a high resistance to flexural fatigue. The rollers may be formed as solid disks of resilient polymer but preferably include deformable cylinders of resilient polymer loosely positioned on the pins. The rollers have unstressed diameters greater than the radial distance between the sun roller and the outer ring, so that the rollers must be compressed in order to be installed therein, thereby creating tractive friction with the sun roller and the outer ring. | ||||||
