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 fittin…
