Abstract
A generator for a direct driven wind turbine configured to convert kinetic energy of a main shaft of the wind turbine into electrical energy. The generator includes a generator rotor connectable to the main shaft of the wind turbine and a generator stator, the generator includes a generator housing on which the generator stator is arranged. The generator housing includes a front side facing towards a rotor head of the wind turbine in an installed state of the generator and a rear side facing away from the rotor head in the installed state of the generator. The generator includes at least one front generator bearing arranged at the front of the generator housing and a rear generator bearing arranged at the rear of the generator housing.

A generator for a direct driven wind turbine configured to convert kinetic energy of a main shaft of the wind turbine into electrical energy,
- wherein the generator comprises a generator rotor connectable to the main shaft of the wind turbine and a generator stator,
- wherein the generator comprises a generator housing on which the generator stator is arranged,
- wherein the generator housing comprises a front side facing towards a rotor head of the wind turbine in an installed state of the generator and a rear side facing away from the rotor head in the installed state of the generator,
- wherein the generator further comprises at least one front generator bearing arranged at the front of the generator housing and a rear generator bearing arranged at the rear of the generator housing,
- wherein the front and the rear generator bearings are configured to support the main shaft on the generator housing in the installed state of the generator,
- wherein the generator comprises at least one support device which is attached directly to the generator housing and which is configured to support the generator housing on a housing of the wind turbine in the installed state.
A method for disassembling a generator from a main shaft of a direct driven wind turbine comprising:
- loosening a front generator rotor fastening device and a rear generator rotor fastening device;
- loosening at least one support device, preferably several support devices;
- and
- sliding down the generator from the main shaft.
