Hollow Rotary Actuator Basic Construction

The basic construction of the THS130 Hollow Rotary Actuator Rotating Platform Table With High Precision Planetary Gearbox includes:

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

The product image is shown below:Each part plays a crucial role in the overall functionality of the actuator. The crossed roller bearing provides high rigidity and accuracy in rotary motion. Precision gears ensure smooth and efficient power transmission. The input mounting flange and shaft allow for easy installation and connection to external systems. The sensing device provides real-time feedback of the actuator's position, which enables precise control of the motion process.

Working Principle

The THS130 Hollow Rotary Actuator Rotating Platform Table With High Precision Planetary Gearbox works based on the following principles:

1. Drive Source: The actuator is typically powered by a motor, which can be a servo motor, stepper motor, or DC motor. The motor converts electrical energy into mechanical energy and delivers it through the output shaft to the transmission system.
2. Transmission Mechanism: The transmission system generally consists of a set of precision gears, such as a planetary gearbox. The motor's power is transmitted to the sun gear through the input shaft, and the sun gear drives a set of planetary gears that rotate around it. These planetary gears simultaneously rotate and revolve around the internal ring gear, thereby achieving torque amplification and reducing the rotation speed. The hollow design of the actuator allows external cables, fluid pipes, or other necessary components to pass through the center of the actuator without affecting its rotation function.
3. Hollow Shaft Design: The core feature of the actuator is an internal, hollow rotating shaft that allows cables, fluid pipes, or other necessary components to pass through the shaft center without affecting the actuator's rotation function. This feature greatly enhances the device's integration in limited spaces.
4. Position Control and Feedback: To achieve precise position control, the Hollow Rotary Actuator is equipped with position sensors, such as encoders or magnetostrictive displacement sensors. These sensing devices detect the actuator's rotation angle in real-time and send 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. Applied Load: The output end of the actuator is connected to the load that needs to rotate through a flange or other interface methods, such as robot joints, radar antennas, medical equipment, etc. This allows for precise continuous or intermittent rotation operations.

The product image is shown below:In summary, the THS130 Hollow Rotary Actuator Rotating Platform Table With High Precision Planetary Gearbox provides high-precision rotary positioning with a compact design, making it an ideal solution for various applications.
