A gear set (200) comprising: an input shaft (201); an output shaft (215); two or more pairs of helical gears (202, 203, 213, 214) of opposite hand, each pair of gears being fixed relative to each other, axially moveable in tandem and mounted on the input or the output shaft; three or more lay shafts (207, 208, 209) each having an input gear (204, 205, 206) engaged with one of the pairs of helical gears (202, 203) and an output gear (210, 211, 212) engaged with a gear (213, 214) on the output shaft (215) for transmitting rotational movement from the input shaft (201 ) to the output shaft (215), wherein the gear set (200) is configured such that an imbalance in load sharing between the lay shafts (207, 208, 209) results in axial movement of the pairs of helical gears (202, 203, 213, 214) tending to reduce the imbalance. |
