Abstract
A transmission gearing includes a sun gear, a planetary unit and a high speed unit. The sun gear is mounted on a slowly rotating gear shaft. The planetary unit includes a planetary toothed gear wheel and a planetary shaft gear wheel, which are both mounted on a planetary shaft. The planetary shaft gear wheel has a diameter that is larger than that of the planetary toothed gear wheel and smaller than that of the sun gear. The planetary toothed gear wheel engages the sun gear. The high speed unit includes a quickly rotating gear shaft on which a high speed shaft gear is mounted. The high speed shaft gear has a diameter that is smaller than that of the planetary shaft gear wheel. A drive belt engages both the planetary shaft gear wheel and the high speed shaft gear. The slowly rotating gear shaft is parallel to the planetary shaft.
