| 143 | A PLANET GEAR | PCT/DK2006000189 | 2006-03-31 | WO2006102906A3 | 2006-12-14 | PEDERSEN TROELS |

| 144 | PLANETARY, FRICTION GEAR SYSTEM | PCT/DE9701360 | 1997-06-27 | WO9800657A3 | 1998-10-29 | HEINZL JOACHIM; ZEHENTBAUER HANS; DORMANN JENS |
| A precision gear system as described in claim 1 is suitable for stepping down fast engines. The working principle as a straight differential, wherein rotating gears (2, 3, 4) and central gears (5, 7) exhibit slight radial differences and one (5) of the two central gears is fixed to the frame, allows a very high reduction in a range higher than about 2500:1 in a single stage. The design as friction gear ensures a smooth run, which can be further improved for the most stringent requirements by reducing redundancy, which in turn is achieved by arranging the three rotation gears, of which two (2, 3) are decoupled. As both central gears are designed as ring gears (5, 7), the mass moment of inertia is reduced by a compact pinion cage. The normal forces caused by the wedging effect between the conical ring gears and the camber ground friction gears (2, 3, 4) are generated by the pressure of a spring washer packet (9). Together with a transmission rod (11) which is laterally pressed against the driven ring gear, this gear system may be used as a forward feeding drive for precision machines. | ||||||

| The present invention is related to a traction drive synchronous governor and a multi-axis drive gearbox with the same, and includes a governor chamber and a speed change gear chamber. The present invention uses the synchronous governor that is deposited in the governor chamber to transmit the power of engine to an output set of the gearbox.
