Main bearing arrangement for a wind turbine

The invention provides a drive train for a horizontal axis wind turbine, comprising -a main shaft provided with a rotor attachment flange adapted to be connected to a rotor of the wind turbine, and -a main bearing housing having a main body at least partly enclosing the main shaft and extending from a first end to a second end, a distance from the second end to the rotor attachment flange being larger than a distance from the first end to the rotor attachment flange, the main body presenting at the second end a component attachment flange for a connection of the housing to a further drive train component, -the main bearing housing carrying the main shaft via a first bearing and a second bearing, a distance between the second bearing and the rotor attachment flange being larger than a distance between the first bearing and the rotor attachment flange, -the main bearing housing having a first seat for the first bearing, and a second seat for the second bearing, -the main bearing housing comprising a seat flange extending from the main body at least partly radially inwards, the second seat being located on a distal end of the seat flange.
