Abstract
The coupling can have a female member having a plurality of female member connections circumferentially arranged along a radially inner face; a male member having a plurality of male member connections circumferentially arranged along a radially outer face; and a coupling member extending annularly around the axis, the coupling member having a strip, the strip having, circumferentially relative the axis, an alternating sequence of outer folds and inner folds, the outer folds connected to the female member via respective ones of the female member connections, the inner folds connected to the male member via respective ones of the male member connections, the inner folds being circumferentially offset from the outer folds in a given angular direction.
Claims15
A coupling comprising:
- a female member rotatable around an axis, defining an axial recess bounded by a radially inner face, and having a plurality of female member connections circumferentially arranged along the radially inner face;
- a male member rotatable around the axis and extending inside the axial recess and having a plurality of male member connections circumferentially arranged along a radially outer face;
- and
- a coupling member extending annularly around the axis between the female member and the male member, the coupling member having a strip, the strip having, circumferentially relative to the axis, an alternating sequence of outer folds and inner folds, the outer folds connected to the female member via respective ones of the female member connections, the inner folds connected to the male member via respective ones of the male member connections, the inner folds being circumferentially offset from the outer folds in a given angular direction.
A system comprising a gas turbine engine having a driving shaft, a generator having a driven shaft, and a coupling between the driving shaft and the driven shaft, the coupling comprising:
- a female member provided as part of one of the driving shaft and the driven shaft, the female member rotatable around an axis, defining an axial recess bounded by a radially inner face, and having a plurality of connections circumferentially arranged along the radially inner face;
- a male member provided as part of the other one of the driving shaft and the driven shaft, the male member rotatable around the axis, the male member extending inside the axial recess and having a plurality of connections circumferentially arranged along a radially outer face;
- and
- a coupling member extending annularly around the axis, the coupling member having a strip, the strip having, circumferentially relative the axis, an alternating sequence of outer folds and inner folds, the outer folds connected to the female member via respective ones of the female member connections, the inner folds connected to the male member via respective ones of the male member connections, the inner folds being circumferentially offset from the outer folds in a given angular direction.
