Types of Hollow Rotary Actuator
Hollow Rotary Indexing Table
A hollow rotary indexing table is a mechanical transmission component with high-precision positioning capabilities. Its core feature is a through hollow hole in the center, combining the dual advantages of rotational motion and precise indexing positioning.
Hollow Rotating Platform
The Hollow Rotating Platform has a hollow design, with a large hollow hole that allows for easy passage of air pipes, wiring, etc. Grinding gear shafts with nitriding treatment results in small deformation, high precision, and good wear resistance. The use of a face gear structure at a 90°angle greatly reduces noise.
Hollow Shaft Rotary Actuator
The Hollow Shaft Rotary Actuator has a hollow design,with a large hollow hole that allows for easy passage of air pipes, wiring, etc.Grinding gear shafts with nitriding treatment results in small deformation,high precision,and good wear resistance. The use of a face gear structure at a 90°angle greatly reduces noise.

Advantages of Hollow Rotary Actuator

 
Hollow Rotary Indexing Table

Simplified Wiring and Piping:The hollow center allows for the passage of cables, pneumatic lines, and even optical fibers through the actuator.This eliminates the need for external routing, reducing clutter and potential interference.Equipment can be designed with a smaller footprint due to the reduced need for space around the actuator for wiring and piping.

 

Reduced Assembly Time and Parts Count:The hollow flange design allows for direct mounting of loads, eliminating the need for couplings or other connecting parts. This reduces the number of components, simplifying assembly and reducing the potential for errors. Reduced parts count also translates to lower costs and less maintenance.

 

Enhanced Precision and Stability:By eliminating the need for external couplings and transmission mechanisms, hollow rotary actuators minimize the impact of component rigidity and assembly errors on accuracy.This leads to more precise and repeatable positioning.

Compact and Lightweight Design:The integrated design, with the motor and hollow output table, results in a more compact unit compared to traditional designs using separate components.This is especially beneficial in applications where space is limited.

 

Increased Flexibility and Design Options:The hollow center provides flexibility in how the actuator is integrated into the overall system. For example, equipment tables or arms can be mounted directly onto the hollow output table, simplifying the design and reducing the need for custom mounting solutions.

 

Improved Rigidity and Load Capacity:Some hollow rotary actuators, like the DGII series from Oriental Motor, utilize cross-roller bearings for high rigidity and load capacity.This allows for handling of heavier loads and withstanding higher moment loads.

Application of Hollow Rotary Actuator
 

Robotics

The hollow shaft facilitates the routing of cables for operating a robot's manipulator arms or hands.

Semiconductors

The actuator's hollow shaft can also accommodate wiring and tubing for inspection equipment and wafer handling systems used in semiconductor manufacturing.

Automation

Actuators enable the routing of pneumatic lines and cables for factory automation equipment.

Machine tools

Milling machines and similar equipment can use hollow shaft actuators to permit the running of sensor cables and coolant lines.

 

Installation Precautions of Hollow Rotary Actuator

Before connecting the motor and the hollow rotating platform, please ensure that the motor shaft keyway is perpendicular to the clamping bolt.

 

To ensure even force, first screw in the installation bolts at any diagonal position, but do not tighten them, then screw in the other two diagonal installation bolts, and finally tighten all four installation bolts one by one.

 

Finally, tighten the clamping bolts. All clamping bolts must be fixed and checked with a torque wrench according to the specified fixed torque data.
