Synthesis of elastic rotatable support of blade swing of a wind turbine based on the elastic coupling

Abstract

Engineering development requires the creation and use of new high-performance rotary elastic supports for solving not only the problem of shaft-type object orientation around the elements of body and the problem of reduce the friction between them but also other important tasks: ensuring appropriate angular orientation of a shaft-type object relatively to the body under the action a certain momentum, reduce the negative manifestations of overloads and vibrations. On the basis of the modified technique using kinematic graphs the synthesis iscarried out and new theoretically informed decision on the establishment of an elastic rotary support of swing of rotor blade based on a flexible coupling with mechanical feedback is proposed. It is shown that synthetic device is obtained on the basis of multiple solutions for different combinations of additional mechanical structures in the form of ordinary and planetary gears. It is found that the results obtained by a particular solution can be used with other existing devices to improve their functionality.
