Hollow Rotary Actuator Structure

1. Cross roller bearing: The cross roller bearing can provide high-precision guidance and rotation support for the rotating platform.
2. Precision gears: The precision planetary gearbox can reduce the rotating speed and increase the output torque.
3. Input flange: The input flange can make the installation more convenient and flexible.
4. Input shaft: The input shaft connects the motor and the gearbox.
5. Sensing devices: The sensing devices such as encoders or magnetostrictive displacement sensors provide accurate position feedback for closed-loop control.

The hollow rotary actuator is mainly driven by a motor and a planetary gearbox. The gearbox consists of a set of precision gears, such as planetary gears. The motor's power is transmitted to the sun gear through the input shaft, driving a set of planetary gears that rotate around the sun gear and also spin around their own axes. This design can reduce the rotating speed and increase the output torque. The hollow shaft design allows cables, fluid pipelines or other necessary components to pass through the center of the actuator without affecting its rotation function. The sensing devices provide accurate position feedback, which can ensure precise motion control of the device.

Hollow Rotary Actuator Working Principle

1. Drive source: The hollow rotary actuator is usually powered by a motor, such as a servo motor, stepper motor or DC motor. The motor converts electrical energy into mechanical energy and transmits it to the transmission system through the output shaft.
2. Transmission mechanism: The transmission system usually contains a set of precision gears, such as planetary gears. The motor's power is transmitted to the sun gear through the input shaft, driving a set of planetary gears that rotate around the sun gear and also spin around their own axes. This design can reduce the rotating speed and increase the output torque.
3. Hollow shaft design: The core feature of the actuator is the internal hollow rotating shaft, which allows cables, fluid pipelines or other necessary components to pass through the center of the actuator without affecting its rotation function. This feature greatly enhances the integration of equipment in limited space.
4. Position control and feedback: To achieve precise position control, the hollow rotary actuator is equipped with sensing devices such as encoders or magnetostrictive displacement sensors. These sensing devices detect the rotational angle of the actuator in real-time and transmit the data back to the control system to form a closed-loop feedback mechanism, ensuring that the actuator moves accurately according to the set target position.
5. Load application: The output end of the actuator is connected to the load that needs to be rotated through a flange or other interface, such as robot joints, radar antennas, medical devices, etc., enabling precise continuous or intermittent rotation operations.
