Abstract
The invention relates to a transmission unit connected in one end to a driving unit, the transmission unit having a large belt disc with at least one large belt extending around and in contact with the large belt disc, and a high speed shaft. The transmission unit includes a planetary carrier being coupled to the driving unit, the planetary carrier carrying at least two planetary belt pulleys, each belt pulley having a belt pulley shaft which is in rotational coupling with the at least one large belt, each planetary pulley having at least one planetary belt, the planetary belt(s) rotationally coupling the planetary pulleys with the high speed shaft, the large belt disc being stationary mounted, the high speed shaft being coupled to a driven unit.
