Serve Motor Drive High Precision Standard Hollow Rotary Platform

  • Serve Motor Drive High Precision Standard Hollow Rotary Platform

●  Introduction

The standard hollow rotary platform is an integrated device combining precision transmission and positioning functions. Its core design features a hollow structure, allowing pipelines (such as tubes and wires) to pass through the center of the rotating table. It can be directly connected to a servo motor. Driven by a servo motor and utilizing gear reduction, this platform achieves high-precision angular control and boasts characteristics such as high rigidity and high repetitive positioning accuracy. It can serve as a replacement for DD motors and cam dividers.

Features

● Hollow Structure Design

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

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


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


● Ultra-High Rotational Accuracy

  • Turntable undergoes secondary grinding to ensure strict geometric tolerances (coaxiality, parallelism), achieving micrometer-level rotational accuracy.

  • Repeat positioning accuracy ≤5 arc-seconds for select models, meeting precision alignment requirements.


● Flexible Compatibility

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

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


● High-Reliability Transmission

  • Single-stage helical gear reducer (precision class ≤5) with adjustable backlash design minimizes transmission error.

  • Precision bevel gear system enables infinite angular adjustment.
