Abstract

A main shaft assembly of a wind turbine and method for manufacturing the same are provided. Accordingly, the main shaft assembly includes a structural / shaft body defining a cavity therein. The shaft body is configured to transmit a load of the wind turbine developed in response to the wind. An inner body is located within the cavity. The inner body is non-loadbearing with respect to the load. At least one sensor is coupled to the inner body and positioned within the cavity for detecting a deflection of the shaft body in response to the load.

Description

Technical field [0001] The present disclosure generally relates to a wind turbine, and more specifically, involving a spindle assembly having a wind power of an embedded sensor. Background technique [0002] Wind power is considered to be one of the most cleaned, most environmentally friendly energy available, and wind turbines have received more and more attention in this regard. Modern wind turbines typically include tower, generators, gearboxes, naches, and one or more rotor blades. The cabin includes a rotor assembly coupled to the gearbox and generator. The rotor assembly and gearbox are mounted on the backplane support frame, which is located in the cabin. One or more rotor blades use known airfoil principles to capture the kinetic energy. The rotor blade is passed in the form of a rotation energy to allow the rotor blade to be coupled to a gearbox (or if the gearbox is not used, directly coupled to the generator) rotor axis. The generator then converts the mechanical energ...
