Basic Construction of the Hollow Rotary Actuator

The Hollow Rotary Actuator consists of five main components:

1. Cross-roller bearing
2. Precision gears
3. Input mounting flange
4. Input shaft
5. Sensing device

Cross-roller bearing

The cross-roller bearing is a key component of the Hollow Rotary Actuator. It provides high rigidity and accuracy, making it ideal for applications that require high precision and repeatability.

Precision gears

The precision gears are another important component of the Hollow Rotary Actuator. They ensure accurate positioning and high torque output. The use of a planetary gearbox allows the device to provide high torque output while maintaining a compact design.

Input mounting flange and input shaft

The input mounting flange and input shaft are used to connect the Hollow Rotary Actuator to the driving motor. The input shaft transfers the motor's power to the gearbox, which then drives the output shaft.

Sensing device

The sensing device is used to detect the device's position accurately. This information is used to provide feedback to the control system, ensuring that the Hollow Rotary Actuator moves to the desired position.

Working Principle of the Hollow Rotary Actuator

The Hollow Rotary Actuator typically uses an electric motor to provide the driving force. The motor can be a servo motor, stepper motor, or DC motor. The motor converts electrical energy into mechanical energy, which is then transmitted to the driving system via the input shaft. The driving system usually consists of a set of precision gears, such as a planetary gearbox. The motor's power is transmitted to the sun gear via the input shaft, and the sun gear drives a set of planetary gears that rotate around it. These planetary gears also revolve around the internal gear, reducing the rotation speed and increasing the torque output. The hollow shaft design is a core feature of the Hollow Rotary Actuator, allowing cables, fluid pipelines, or other necessary components to pass through the shaft center without affecting the device's rotation function. To achieve accurate position control, the Hollow Rotary Actuator is equipped with position sensors, such as encoders or magnetostrictive displacement sensors. These sensors detect the device's rotational angle in real-time and transmit the data back to the control system, forming a closed-loop feedback mechanism that ensures the device moves accurately to the desired position. The device connects to the output end via a flange or other interface method to the rotating load, such as a robot joint, radar antenna, or medical equipment, enabling precise continuous or intermittent rotation operations.
