COMPACT ELECTRICALLY DRIVEN LINEAR ACTUATOR |
摘要 |
A compact electrically driven linear actuator having an electric motor in a housing. The electric motor has a cylindrically-shaped rotor assembly which is attached to and circumscribes a threaded spindle. A portion of the threaded spindle is received in an axial bore of a non-rotatable extendable arm. A nut attached to one end of the non-rotatable extendable arm is threadably received on the threaded spindle. Rotation of the threaded spindle by the electric motor linearly displaces the nut and the non-rotatable extendable arm along the length of the threaded spindle. In the preferred embodiment, the threaded spindle has a helical ball groove and the nut is a mating ball nut. |
