●  Introduction

A planetary hollow rotary table is an integrated system combining a planetary gear reducer with a hollow rotary platform, offering a wider range of gear ratios tailored to specific applications. Its core design features a hollow structure, allowing pipelines (e.g., air tubes, electrical cables) to pass through the center of the turntable, eliminating the cable entanglement issues common in traditional rotary mechanisms. Driven by a servo motor, the platform achieves high-precision angular control through gear reduction or worm gear transmission, delivering exceptional rigidity and repeat positioning accuracy.

Features

● Hollow Structure Design

  • Central hollow channel enables media transmission (air/liquid/electrical), simplifying equipment layout.

  • Side-mounted motor interface prevents interference between pipelines and moving components.


● Integrated Planetary Gear Reducer
Offers multiple gear ratio options to match specific application requirements.


● High-Rigidity Support
Precision cross roller bearings with 90° staggered preloaded rollers withstand radial, axial, and overturning loads, delivering 5-10x higher rigidity than conventional bearings.


● High Rotational Accuracy
Turntable undergoes secondary grinding to ensure strict geometric tolerances (coaxiality, parallelism), achieving superior rotational precision.


● Flexible Compatibility

  • Compatible with any brand of servo/stepper motors; supports custom flanges and shaft-bore interfaces.

  • Modular design enables horizontal/vertical installation for enhanced scalability.
