Technical Parameter

Basic Structure of Hollow Rotary Actuator

The basic structure of Hollow Rotary Actuator includes:

1. Cross roller bearings
2. Precision gears
3. Input mounting flange
4. Input shaft
5. Induction device

Cross Roller Bearings

Cross roller bearings are the key components of the Hollow Rotary Actuator that provide high rigidity, high load capacity, and high precision.

Precision Gears

The precision gears of the Hollow Rotary Actuator are designed to provide high torque output and low backlash. The planetary gearbox is commonly used in the Hollow Rotary Actuator due to its compact design and high gear reduction ratio.

Input Mounting Flange

The input mounting flange is used to mount the Hollow Rotary Actuator onto a device. It is designed to provide a rigid connection and accurate alignment.

Input Shaft

The input shaft connects the Hollow Rotary Actuator to the driving source, such as a motor. It is designed to provide high torque transmission and accurate position control.

Induction Device

The induction device, such as an encoder or magnetostrictive displacement sensor, is used to provide accurate position feedback for closed-loop control.

Working Principle of Hollow Rotary Actuator

The Hollow Rotary Actuator works based on the following principles:

1. 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.
2. Transmission Mechanism: The transmission system usually contains a set of precision gears, such as a planetary gearbox. The power from the motor is transmitted to the sun gear through the input shaft, and the sun gear drives a set of planetary gears that rotate around the sun gear and also rotate around their own axes. This design provides high torque output and low rotation speed.
3. Hollow Shaft Design: The core feature of the Hollow Rotary Actuator is the hollow rotating shaft, which allows cables, fluid pipes, or other necessary components to pass through the center of the shaft without affecting the rotation function of the actuator itself. This feature greatly enhances the integration ability of the equipment in limited space.
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 sensors detect the rotation angle of the actuator in real-time and send the data back to the control system to form a closed-loop feedback mechanism, which ensures the actuator moves accurately according to the set target position.
5. Load Application: The output end of the actuator is connected to the load, such as robot joints, radar antennas, medical devices, etc., through a flange or other interface, so that it can rotate accurately and continuously or intermittently.
