ELECTRIC ACTUATOR FOR A MARINE STEERING SYSTEM |
| 摘要 |
An electric actuator comprises a housing and an output shaft reciprocatingly received by the housing. There is a screw assembly disposed within the housing and coupled to the output shaft. The screw assembly includes a plurality of annular rollers and a central screw received by the annular rollers. The annular rollers are rotatable about the central screw. There is a motor which includes a stator and a rotor. The rotor has an inner bore which engages the annular rollers. Rotation of the rotor causes the central screw to translate axially relative to the rotor and the output shaft to reciprocate relative to the housing. |

1. An electric actuator for a marine steering system, the electric actuator comprising:
a housing; an output shaft reciprocatingly received by the housing; a screw assembly disposed within the housing and coupled to the output shaft, the screw assembly including a plurality of annular rollers and a central screw received by the annular rollers, the annular rollers being rotatable about the central screw; and a motor including a stator and a rotor, the rotor having an inner bore which engages the annular rollers, wherein rotation of the rotor causes the central screw to translate axially relative to the rotor and the output shaft to reciprocate relative to the housing. |
