Dismantling a gear mechanism of a wind power plant

摘要

A gear mechanism (22) of a wind power plant (10) that includes at least one planetary stage (24.1, 24.2) that has at least one planet gear carrier (41, 61) and a method for dismantling a multi-stage gear mechanism (22) of a wind power plant (10). The gear mechanism (22) is arranged in a nacelle (15) arranged on a tower (11) of a wind power plant (10). The gear mechanism (22) has at least one planetary stage (24.1, 24.2) and the at least one planetary stage (24.1, 24.2) has a planet gear carrier (41, 61) and several planet gears (45, 65) held in the planet gear carrier (41, 61) using planetary bolts (47, 67). The planet gears (45, 65) are in operative connection with a ring gear (49, 69) of the planetary stage (24.1, 24.2) surrounding the planet gears (45, 65).

1. A method for dismantling a multi-stage gear mechanism (22) of a wind power plant (10), the gear mechanism (22) being arranged in a nacelle (15) arranged on a tower (11) of a wind power plant (10), the gear mechanism (22) having at least one planetary stage (24.1, 24.2) that has a planet gear carrier (41, 61) and a plurality of planet gears (45, 65) held in the planet gear carrier (41, 61) using planetary bolts (47, 67), the planet gears (45, 65) being in connection with a ring gear (49, 69) of the planetary stage (24.1, 24.2) surrounding the planet gears (45, 65), the method comprising the steps of:
axially distancing the ring gear (49, 69) and the planet gears (45, 65) from each other along a substantially horizontal axis such that engagement between the planet gears (45, 65) and the ring gear (49, 69) is released, wherein at least one of the planet gears (45, 65) that are held in the planet gear carrier (41, 61) are accessible from an outside, releasing a retaining connection between the planet gear (45, 65) and the planet gear carrier (41, 61) before or after the axial distancing of the ring gear (49, 69) and the planet gears (45, 65), releasing the planetary bolt (47, 67) from a clamped position thereof in a clamp device before the removal of the planet gear (45, 65) from the retained position in a bolt receptacle of the planet gear carrier (41, 61), removing the planet gear (45, 65) released from the retaining connection to the planet gear carrier (45, 65) in a radially outward direction to a longitudinal axis of the gear mechanism.
