WebbThe motion of planetary gear systems is expressed clearly in the Plantetary Train Equation: -S/R = (ωr-ωa)/ (ωs-ωa). Once this is known, the speeds of the carrier arm, sun and/or ring can be calculated. Multiple series of planetary gear systems can be used to get multiple speeds and directions. Planetary gear systems are used everywhere. Webb1 maj 2024 · This task is all the more difficult the more PGT stages are included in the gear unit.

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”.
