Basic Construction of Hollow Rotary Actuator

The basic construction of the Hollow Rotary Actuator includes:

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

Cross Roller Bearing

The cross roller bearing is designed to handle both radial and axial loads. It provides high rigidity and accuracy for the actuator.

Precision Gear

The precision gear is used to transmit power from the input shaft to the output shaft. It is a high-precision component that ensures the accuracy and efficiency of the actuator.

Input Mounting Flange

The input mounting flange is used to connect the actuator to the driving source, such as a motor or a gearbox.

Input Shaft

The input shaft is used to transmit power from the driving source to the actuator. It is connected to the precision gear.

Sensing Device

The sensing device is used to detect the position of the actuator and provide feedback to the control system. This allows for precise position control of the actuator.The Hollow Rotary Actuator uses a driving source, a transmission mechanism, a hollow shaft design, position control and feedback, and load application to achieve precise and continuous rotation in various applications.

Working Principle of Hollow Rotary Actuator

The working principle of Hollow Rotary Actuator can be divided into five parts:

1. Driving source
2. Transmission mechanism
3. Hollow shaft design
4. Position control and feedback
5. Load application

The driving source is usually 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. The transmission system usually includes a set of precision gears, such as a planetary gearbox. The power from the motor is transmitted to the sun gear, which drives a set of planetary gears that rotate around the sun gear and also rotate around their own axis. This achieves torque amplification and reduces the rotation speed. The hollow shaft design allows cables, fluid lines, or other necessary components to pass through the center of the actuator without affecting the rotation of the actuator itself. The position control and feedback system includes position sensors, such as encoders or magnetostrictive displacement sensors, which detect the rotation angle of the actuator and provide data to the control system. Load application is achieved by connecting the output end of the actuator to the load through a flange or other interface.The Hollow Rotary Actuator provides high torque output in a compact size, which makes it suitable for various applications that require precise and continuous rotation.
