Abstract: A powertrain for a wind turbine (100) comprises at least a first powertrain component (21, 22, 23, 26) and a second powertrain component (21, 22, 23, 26). A rotating output of the first powertrain component (21, 22, 23, 26) is coupled to a rotating input of the second powertrain component (21, 22, 23, 26) and a powertrain housing enclosing the powertrain components (21, 22, 23, 26), the powertrain housing comprising at least a first powertrain housing section (211, 221, 231, 261) enclosing at least part of the first powertrain component (21, 22, 23, 26) and a second powertrain housing section (211, 221, 231, 261) enclosing at least part of the second powertrain component (21, 22, 23, 26). A connection between the first and the second powertrain housing sections (211, 221, 231, 261) comprises a plurality of bolts (42) installed in corresponding bolt holes (421) of the first and the second powertrain housing sections (211, 221, 231, 261), and a plurality of dowel pins (43) installed in corresponding dowel pin holes (431) of the first and the second powertrain housing sections (211, 221, 231, 261), the dowel pins (43) having been installed in the dowel pin holes (431) by shrink fitting.

Abstract: A wind turbine drive train component (22) comprising a rotating shaft (61) with a radial seal (50) is provided. The radial seal (50) comprises a stationary part and a rotating part. The stationary part comprises a ring (51) with an inner edge and an outer edge, the inner edge being configured for contactlessly surrounding the shaft (61). The rotary part comprising a disc (52), coaxially connected to the shaft (61) for rotation therewith and comprising a flange (53) that wraps around the outer edge of the ring (51). The radial seal (50) further comprises an annular air lock gap (55) for containing an amount of lubrication fluid (64) and thereby closing off the air lock gap (55) when the rotary part rotates at a rotational speed above a predetermined threshold speed, the annular air lock gap (55) being formed by an inner surface of the flange (53), an outer part of the opposing parallel surface of the disc (52) and the outer edge of the ring (51).
