Abstract
A drivetrain for a horizontal axis wind turbine includes a main shaft, 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 bearing housing: carries 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; has a first seat for the first bearing, and a second seat for the second bearing; and includes 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.
