Webb10 mars 2024 · A planetary gear can also be used as a so-called direct drive. The carrier and the sun gear are firmly fixed to the ring gear. In this case, the rotary motion is transmitted directly from the input shaft to the output shaft (transmission ratio 1:1). Such a direct drive is used, for example, in three-speed gear hubs as the “2nd gear”.

Actually there are … WebbThe Ravigneaux improves upon earlier planetary automobile transmissions, such as the Simpson, which has two complete planetary gearsets. As originally invented, the Ravigneaux puts two planetary gear trains on a single planet carrier. It has two sun gears, two ring gears, and two sets of planet gears on a single carrier. Webb4 Planet gears (pinions) A typical gear train includes the input shaft; planetary gear set, and output shaft. Two different types of gear trains are used. A simple, or “Simpson,” gear train and a compound or “Ravigneaux” gear train. A planetary gear set has three members: the ring gear, the sun gear, and the pinion (or “planet”) gears. how to resolve gap in standby database
