THG130 Hollow Rotary Actuator Rotating Platform Table With High Precision Planetary Gearbox
THG130 Hollow Rotary Actuator Rotating Platform Table With High Precision Planetary Gearbox
Overview
THG130 Hollow Rotary Actuator Rotating Platform Table With High Precision Planetary Gearbox is a high-precision, high-performance motion control product. It is also known as Hollow Rotary Platform and Hollow Rotary Table. It is widely used in many areas, such as robot technology, aerospace, medical equipment, military equipment, optical instruments, and industrial automation. The product has a compact structure and a hollow rotary shaft, which allows cables, fluid pipelines, or other necessary components to pass through the center of the shaft without affecting the rotation of the actuator itself.

Construction
The basic construction of the Hollow Rotary Actuator includes the following parts:
- Crossed roller bearing.
- Precision gear.
- Input mounting flange.
- Input shaft.
- Induction device.
Each part has its own definition and function. The crossed roller bearing provides high rotational accuracy and rigidity. The precision gear ensures high torque transmission with minimal backlash. The input mounting flange allows for easy installation and connection to other equipment. The input shaft connects the actuator to the motor or other power source. The induction device provides feedback on the position of the actuator.

Working Principle
The working principle of the Hollow Rotary Actuator can be explained in the following five points:
- 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 input shaft.
- Transmission Mechanism: The transmission system generally includes 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 rotate and revolve around the internal ring gear, thereby achieving torque amplification and reducing the rotation speed. This design allows the hollow rotary actuator to provide high torque output while maintaining a compact structure.
- 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 shaft without affecting the actuator's rotation function. This feature greatly enhances the equipment's integration in limited space.
- 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 sensors detect the actuator's rotational angle in real-time and transmit the data back to the control system, forming a closed-loop feedback mechanism, ensuring that the actuator operates accurately according to the set target position.
- Load Application: The output end of the actuator is connected to the load that needs to be rotated through a flange or other interface method, such as robot joints, radar antennas, medical equipment, etc., enabling precise continuous or intermittent rotation operations.

Design and Selection Considerations
The design and selection considerations of the Hollow Rotary Actuator include the following factors:
| Factor | Description |
|---|---|
| Load requirements | The type, weight, and size of the load that the actuator needs to handle. |
| Motion requirements | The required range of motion, speed, and accuracy for the specific application. |
| Environmental requirements | The environmental factors that affect the operation of the actuator, such as temperature, humidity, and vibration. |
| Integration requirements | The compatibility of the actuator with other equipment and systems in the application. |
Applications
The applications of the Hollow Rotary Actuator include the following areas:
- Robot technology: The actuator is widely used in robot joints, providing high-precision and high-reliability motion control.
- Aerospace: The actuator is used in satellite antennas, solar panels, and other aerospace equipment.
- Medical equipment: The actuator is used in medical equipment such as CT scanners, X-ray machines, and surgical robots.
- Military equipment: The actuator is used in military equipment such as missile launchers and surveillance systems.
- Optical instruments: The actuator is used in optical instruments such as telescopes, cameras, and laser cutting machines.
- Industrial automation: The actuator is used in various industrial automation equipment, such as assembly lines, conveyors, and packaging machines.
