Abstract
Hydraulic powered assemblies 10 and 110 are disclosed. The assembly 10 includes a support unit 12, a hydraulic motor 14, and a driven member 16 that is integral with the hydraulic motor 14. The hydraulic motor 14 includes a power group 32 that includes six gerotor power units 34a-34f. Each gerotor power unit 34a-34f includes an inner rotor 40 that is fixed to a stationary through-shaft 24 and an outer rotor 42 that is mounted for hypocycloidal movement relative to the inner rotor 40. The driven member 16 includes segments 51 that support the outer rotors 40 within the segments 51. The segments 51 carry a winch cable receiving member 60 when the assembly 10 is used as a winch. The hydraulic powered assembly 110 is an alternative embodiment that includes two power groups 131 and 132. The power groups 131 and 133 may be symmetrical or asymmetrical.
