Abstract
A hydraulic rotary gearless actuator includes an input stage and an output stage. The input stage includes a piston linearly translatable within an input cylinder. The output stage includes first and second output cylinders defining first and second tracks, respectively, and a trunnion assembly connected to the piston and including first and second rollers engageable with the first and second tracks, respectively. The output stage is configured to convert linear translation of the piston into rotation of the first output cylinder relative to the second output cylinder by the trunnion assembly being driven linearly by the linear translation of the piston and the first and second rollers engaging with the first and second tracks, respectively.
