Basic Construction

The basic construction of the Hollow Rotary Actuator includes the following parts:

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

1. Crossed roller bearing: This bearing provides the rotary support for the Hollow Rotary Actuator. It is designed to handle heavy loads and provide high stiffness and accuracy.2. Precision gear: A high-precision planetary gearbox is used to reduce the output speed and increase the output torque. It consists of a sun gear, planet gears, and ring gear.3. Input mounting flange: The input flange is used to attach the Hollow Rotary Actuator to a motor or other drive system.4. Input shaft: The input shaft transfers the motion from the motor to the planetary gearbox.5. Sensing device: A feedback device such as an encoder or magnetostrictive displacement sensor is used to provide closed-loop position control of the Hollow Rotary Actuator.

Working Principle

The working principle of the Hollow Rotary Actuator can be described in the following steps:

1. Drive source: The Hollow Rotary Actuator is powered by a motor, which can be a servo motor, stepper motor, or DC motor. The motor converts electrical energy into mechanical energy and transmits it to the transmission system via the input shaft.
2. Transmission mechanism: The transmission system usually 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 rotate around the internal ring gear and rotate simultaneously, 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 size.
3. Hollow shaft design: The core feature of the actuator is an internal hollow rotating shaft that allows cables, fluid pipelines, or other necessary components to pass through the axis without affecting the actuator's rotation function. This feature greatly enhances the equipment's integration 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 actuator's rotation angle in real-time and transmit the data back to the control system, forming a closed-loop feedback mechanism to ensure that the actuator moves accurately to the target position.
5. Load application: The output end of the actuator is connected to the load that needs to be rotated, such as robot joints, radar antennas, medical equipment, etc., through a flange or other interface, allowing for precise continuous or intermittent rotation operations.
