ABSTRACT:
A transmission including a main transmission and a subtransmission. The subtransmission is a planetary gear mechanism incoporating a sun gear, planetary pinions, and a ring gear. The main transmission incorporates a tubular intermediate shaft and an output shaft parallel to it, and several pairs of helical gears mounted on the shafts for transmitting rotational power between them. A driven power input shaft passes through the central hole of the tubular intermediate shaft, protrudes from its end, and is connected to a carrier which supports the planetary pinions. The ring gear is connected to the intermediate shaft. The handednesses of the helical ring gear and of at least one of the helical gear wheels on the intermediate shaft are so arranged that when the subtransmission is transmitting power in the speed increasing state, and that helical gear wheel is transmitting power to the power output shaft, the senses of the axial forces exerted on these two gears by the meshing contacts on their teeth are opposed, so that they tend to cancel one another.
