Title:
DIRECT ACTING TYPE ELECTRIC ACTUATOR
Document Type and Number:
Japanese Patent JP2018078698
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To downsize and improve mountability of a direct acting type electric actuator in which an electric motor unit and a screw mechanism unit are arranged coaxially.SOLUTION: A direct acting type electric actuator includes an electric motor unit A, a screw mechanism unit B, and an operation unit C. The electric motor unit A and the screw mechanism unit B are arranged coaxially. Rotary motion of a hollow rotor inner 52c of the electric motor unit A is transmitted to a nut 92 of the screw mechanism unit B. In the direct acting type electric actuator 1 in which the operation unit C is provided with a screw shaft 93 of the screw mechanism unit B, the hollow rotor inner 52c and the nut 92 are arranged at a position so as not to be overlapped in the axial direction, and a whirl stop mechanism M of the screw shaft 93 is provided inside the hollow rotor inner 52c in the radial direction.SELECTED DRAWING: Figure 1
