Abstract

The invention discloses an electrodynamic actuator, which comprises a housing, wherein an electric machine is disposed in a chamber of the housing; an output shaft of the electric machine is connected with a worm; the worm is engaged with a worm wheel at the upper end of the worm; a mid gear is fixedly connected to the worm wheel shaft of the worm wheel; the mid gear is engaged with a transmitting gear at the right end of the mid gear; the transmission gear is connected with a power take-off by a transmission shaft; and the power take-off is a cam. By using the cam as the power take-off, the electrodynamic actuator can make rotational movement, and the rotational movement of the actuator can be converted into lineal movement, thereby achieving the two rotational and linear functions of the actuator. In addition, by adopting the cam as a power transmission device, the transmission can be smooth, without impact, and has small noise.

Example Embodiment

[0013] Please refer to figure 1 As shown, figure 1 It is a schematic diagram of the structure of an electric actuator of the present invention.
[0014] In this embodiment, an electric actuator includes a housing 9. A motor 1 is arranged in the cavity of the housing 9. The motor 1 is a reversible motor and is connected to an external power source through a connecting plate 3. A worm 2 is connected to the output shaft of 1, and the worm 2 is meshed with the worm wheel 4 at the upper end, and an intermediate gear 5 is fixedly connected to the worm shaft of the worm wheel 4, and the intermediate gear 5 meshes with the transmission gear 8 at the right end The transmission gear 8 is connected to a power output device through a transmission shaft 7, and the power output device is a cam 6, and the cam 6 has a crescent-shaped structure.
[0015] The working principle of the present invention is: the external control current enters the motor 1 through the connecting plate 3, the output shaft of the motor 1 rotates under the action of the current and drives the worm 2 to rotate, the worm 2 drives the worm wheel 4 that meshes with it to rotate, and the worm wheel 4 drives it The connected intermediate gear 5 rotates, the intermediate gear 5 drives the transmission gear 8 to rotate, and the transmission gear 8 drives the cam 6 through the transmission shaft 7. Since the power transmission device adopts the cam 6 structure, it can not only rotate, but also rotate the actuator Rotational motion is converted into linear motion, which realizes the functions of actuator rotation and linear motion. In addition, the use of cams as the power transmission device has soft transmission, no impact, and low noise.
