The present disclosure is directed to a working platform mounted within a nacelle of the wind turbine during a repair procedure. More specifically, the working platform may be mounted to a bedplate within the nacelle in an area where one or more drivetrain component(s) would normally be during operation of the wind turbine, but have been removed due to repair or replacement thereof.

Working platform within a nacelle of a wind turbine

The present disclosure is directed to a clamping apparatus for securing a main bearing of a wind turbine. The clamping apparatus includes a clamp member configured for securement to a seal ring arranged with the main bearing, at least one clamping fastener configured through the clamp member, and at least one jacking fastener configured through the clamp member. Thus, the clamping fastener is configured to tighten the clamp member around the seal ring, whereas the jacking fastener is configured to push against the main bearing when tightened so as to maintain the main bearing in place during and installation and/or repair procedure.

Clamping apparatus for securing a main bearing of a wind turbine during an installation and/or repair procedure

An apparatus and method for removing or installing a bearing unit at the downwind end of the bedplate in wind turbine uses a frame erected at the downwind end of the bedplate. The frame has cradle members located such that the bearing unit can be slid out of the bedplate and supported on the cradle members, or supported on the cradle members and pushed into the bedplate.

Apparatus and method for removing or installing a bearing unit in a wind turbine bedplate with an adjustable bearing support

A method and system for removing or installing a main shaft and attached main bearing assembly of a wind turbine from a bedplate form an extension onto a downwind end of the main shaft with one or more support elements to support the mains shaft on a bearing unit as it is pulled or pushed into the bedplate.
