Abstract
Provided is an electric actuator, including: a drive part (2); a motion conversion mechanism part (3) configured to convert a rotary motion from the drive part (2) into a linear motion in an axial direction parallel with an output shaft of the drive part (2); a driving force transmission part (4) configured to transmit a driving force from the drive part (2) to the motion conversion mechanism part (3); and a motion-conversion-mechanism support part (5) configured to support the motion conversion mechanism part (3), and wherein the drive part (2) and the motion-conversion-mechanism support part (5) are capable of being coupled to and decoupled from the driving force transmission part (4).
Claims5
An electric actuator, comprising:
- a drive part;
- a motion conversion mechanism part configured to convert a rotary motion from the drive part into a linear motion in an axial direction parallel with an output shaft of the drive part;
- a driving force transmission part configured to transmit a driving force from the drive part to the motion conversion mechanism part;
- and
- a motion-conversion-mechanism support part configured to support the motion conversion mechanism part,
- wherein the drive part comprises a driving motor and a motor case configured to accommodate the driving motor,
- wherein the driving force transmission part comprises a transmission gear mechanism configured to transmit the driving force from the drive part to the motion conversion mechanism part, and a transmission gear case configured to accommodate the transmission gear mechanism,
- wherein the motion-conversion-mechanism support part comprises a support bearing configured to support the motion conversion mechanism part, and a bearing case configured to accommodate the support bearing, and
- wherein the drive part and the motion-conversion-mechanism support part are capable of being coupled to and decoupled from the driving force transmission part.
