Title: ELECTRIC ACTUATOR
Abstract:
Provided is an electric actuator equipped with a drive unit 2, a motion converting mechanism 3 for converting rotary motion from the drive unit 2 to linear motion in an axial direction parallel to the output shaft of the drive unit 2, a driving force transmission unit 4 for transmitting driving force from the drive unit 2 to the motion converting mechanism 3, and a motion converting mechanism support unit 5 for supporting the motion converting mechanism 3, the drive unit 2 being provided with a driving motor 10 and a motor case 11 for housing the driving motor 10, the driving force transmission unit 4 being provided with a transmission gear mechanism 28 for transmitting driving force from the drive unit 2 to the motion converting mechanism 3, and a transmission gear case 29 for housing the transmission gear mechanism 28, and the motion converting mechanism support unit 5 being provided with a support bearing 40 for supporting the motion converting mechanism 3, and a bearing case 41 for housing the support bearing 40. The drive unit 2 and the motion converting mechanism support unit 5 can be connected to and separated from the driving force transmission unit 4.
