Abstract
An actuator includes an input shaft, a wave generator, a pair of flex splines, a pair of earth annuli, and an output annulus. Each of the pair of flex splines are earthed to an earth annulus. The output annulus comprises a circular spline. The wave generator is configured to be activated by rotation of the input shaft, and the wave generator is configured to elastically deform both of the pair of flex splines when the input shaft activates the wave generator.
Claims14
An actuator, in which the actuator comprises an input shaft, a wave generator, a pair of flex splines, a pair of earth annuli, and an output annulus, in which
- each of the pair of flex splines are earthed to an earth annulus,
- the output annulus comprises a circular spline,
- the wave generator is configured to be activated by rotation of the input shaft, and
- the wave generator is configured to elastically deform both of the pair of flex splines when the input shaft activates the wave generator;
- wherein each of the pair of the flex splines is cup shaped including a radially extending cup base and a side wall extending from the cup base, the input shaft and each of the flex splines are coaxial, and the flex splines face in opposite directions.
