Gear device for wind turbine

Abstract

There is described a gear device (1) comprising: - two parallel planetary gears (22) arranged one behind the other along a rotation axis (A) of the gear device (1), each planetary gear comprises a sun gear (24), a ring gear (28) and a set of planet gears (26), the two sets of planet gears (26) are arranged in a common planet gear carrier (30), and the two sun gears (24) are connected to a common rotary shaft (32) along the rotation axis (A) of the gear device (1); - a gear device housing (42) which encircles at least a portion of the two planetary gears (22), where the gear device (1) further comprises an internal torque distributor (43) connected to each of the ring gears (28) and to the gear device housing (42), so that the two ring gears (28) are allowed to twist relative to each other around the rotation axis (A) during use. Also described is a gear assembly (10) comprising two such gear devices (1) as well as a wind turbine comprising a gear device (1) or a gear assembly (10).
