High Torque Hat Style Large Hollow Shaft Harmonic Reduction Gear

● Introduction

The FHG-AH series harmonic reduction gear is engineered for high-torque, large hollow shaft, and heavy-load applications. Featuring a top-hat style flexspline and a wave generator cam with an oversized hollow shaft structure, this series enables effortless routing of cables, lead screws, and optical pathways through its central cavity, effectively addressing challenges associated with passing large components. It delivers an optimized solution for such requirements. The series typically employs synchronous pulley connections or large hollow shaft gear structures for input integration.

Features

● Large hollow shaft and bore design facilitates passage of oversized components

● Increased torque capacity, enhanced load-bearing performance, and superior rigidity

● Exceptional rotational accuracy and repeatable positioning precision

● Ideal for machinery demanding specialized torque, hollow shaft/bore integration, and high-load capabilities
