THG200 Hollow Rotary Actuator Rotating Platform Table With High Precision Planetary Gearbox

The THG200 Hollow Rotary Actuator Rotating Platform Table With High Precision Planetary Gearbox is a precision mechanical device used for rotating loads around a fixed axis. It consists of a high-precision planetary gearbox and a hollow rotary platform, also known as a hollow rotary table. This product is widely used in various industries such as robotics, aerospace, medical equipment, military equipment, optical instruments, and industrial automation.

Basic Structure

The basic structure of the Hollow Rotary Actuator is made up of five main parts, including:

1. Crossed roller bearing
2. High-precision gear
3. Input mounting flange
4. Input shaft
5. Sensing device

Each component plays a significant role in the operation of the actuator. The crossed roller bearing provides support for the rotary table, while the high-precision gear ensures accurate and smooth movement. The input mounting flange and shaft connect the device to the power source, while the sensing device provides real-time feedback to the control system.

Working Principle

The Hollow Rotary Actuator typically uses a motor as its power source, such as a servo motor, stepper motor, or DC motor. The motor converts electrical energy into mechanical energy, which is transmitted to the transmission system via the input shaft. The transmission system consists of a precise set of gears, such as a planetary gear set. The motor's power is transmitted to the sun gear, which drives a set of planetary gears that orbit around the sun gear and rotate around their own axes. This design allows the actuator to provide high torque output while maintaining a compact structure size.

The core feature of the actuator is the hollow rotary axis, which allows cables, fluid pipelines, or other necessary components to pass through the axis without affecting the actuator's rotational function. To achieve precise position control, the actuator is equipped with position sensors, such as encoders or magnetostrictive displacement sensors. These sensing devices detect the actuator's rotational angle in real-time and feedback the data to the control system, forming a closed-loop feedback mechanism to ensure the actuator's accurate motion according to the set target position. The actuator's output end is connected to the load that needs to be rotated, such as robot joints, radar antennas, medical equipment, etc., through flanges or other interface methods, enabling precise continuous or intermittent rotation.

Design and Selection Considerations

When designing and selecting a Hollow Rotary Actuator, factors to consider include:

Applications

The Hollow Rotary Actuator has a wide range of applications in various fields, including:

1. Robotics technology: used in robotic arms, grippers, and other motion control applications
2. Aerospace: used in satellite tracking systems, missile guidance systems, and other aviation and space applications
3. Medical equipment: used in CT scanners, X-ray machines, and other medical imaging applications
4. Military equipment: used in radar systems, surveillance systems, and other military applications
5. Optical instruments: used in telescopes, laser scanners, and other precision optical instrument applications
6. Industrial automation: used in CNC machines, packaging machines, and other industrial automation applications

Each application requires precise control and positioning of loads around a fixed axis, which is made possible by the Hollow Rotary Actuator.
