SYHG-Ⅰ Series Harmonic Drive

SYHG-Ⅰ Series Harmonic Drive
Hollow Shaft Flanged Structure | Large Passage | Fully Sealed

Product Overview
The SYHG-Ⅰ Series features a hollow, flanged, standard-structure flexspline. A large-diameter hollow shaft passes through the center of the wave generator cam. The reducer incorporates internal support bearings and a fully sealed design for easy installation — making it especially suitable for applications where cables or other components must pass through the center of the reducer.

Key Features

Cup-Type Standard Structure
Proven, robust design with strong mounting compatibility for easy system integration.
Zero Backlash
Gear engagement without backlash eliminates lost motion and improves control response.
Coaxial Input & Output
Simplifies the drivetrain and reduces installation space.
High Positioning & Rotational Accuracy
Delivers excellent angular precision and repeatability for demanding positioning tasks.

Typical Application Scenario
Rigid circular spline fixed, flexspline as output – ready for integration into robotic joints, rotary tables, and precision positioning systems.
