Abstract

The present invention provides a planetary gear unit (23) for a gearbox for a wind turbine, the planetary gear unit (23) comprising a ring gear (10), a sun gear (11) and planet gears (25, 26). The ring gear (10) and sun gear (11) are each provided with double helical gearing and are each made of one monolithic piece. The planet gears (25, 26) are rotatably mounted on planet shafts (14) in a planet carrier (24) by means of bearings (13) and are mounted between the ring gear (10) and sun gear (21) for mutual interaction. A first number of planet gears (25) is provided in a first plane (A) and a second number of planet gears (26) is provided in a second plane (B), the second plane (B) being axially displaced over a distance (D) with respect to the first plane (A), and the planet gears (25) in the first plane (A) are axially displaced with respect to the planet gears (26) in the second plane (B). According to embodiments of the present invention, the planet carrier (24) comprises two separate parts (27, 28), wherein a first part (27) of the planet carrier (24) is provided with a first number of planet shafts (14) for the first number of planet gears (25) and a second part (28) of the planet carrier (24) is provided with a second number of planet shafts (14) for the second number of planet gears (26), and wherein the first and second part (27, 28) are complementary.
