Abstract
Provided is an electric actuator, including: a driving motor (2); a motion conversion mechanism (6) configured to convert a rotary motion of the driving motor (2) to a linear motion; a transmission gear mechanism (5) configured to transmit a driving force from the driving motor (2) to the motion conversion mechanism (6); and a speed reduction mechanism (3) configured to reduce a speed of the rotary motion of the driving motor (2), and output the rotary motion reduced in speed to the transmission gear mechanism (5), wherein a side of one end portion of a rotation shaft (18) of a gear (16) of the transmission gear mechanism (5) is rotatably supported by a bearing (19), and a side of another end portion of the rotation shaft (18) of the gear (16) is rotatably supported by the output shaft (2a) of the driving motor (2).
Claims4
An electric actuator, comprising:
- a driving motor;
- a motion conversion mechanism configured to convert a rotary motion of the driving motor to a linear motion in an axial direction parallel with an output shaft of the driving motor;
- a transmission gear mechanism configured to transmit a driving force from the driving motor to the motion conversion mechanism;
- and
- a speed reduction mechanism configured to reduce a speed of the rotary motion of the driving motor, and output the rotary motion reduced in speed to the transmission gear mechanism,
- wherein a side of one end portion of a rotation shaft of a gear of the transmission gear mechanism is rotatably supported by a bearing, and a side of another end portion of the rotation shaft of the gear is rotatably supported by the output shaft of the driving motor.
