Easy Installation Strain Wave Gear for Robot Arm and Sealed Rotary Tables

● Introduction

The FSG-II series strain wave gear utilizes a cross slider coupling mechanism for its wave generator. The cam shaft bore dimensions can be customized to accommodate specific motor models. The input shaft directly engages with the wave generator’s inner bore through a keyed connection. This configuration is typically implemented with the circular spline fixed at the base and the flexspline serving as the output end.

Features

● The wave generator adopts an integrated cam structure, which provides greater tolerance to machining precision of components, enables self-aligning capability, and maintains coaxial alignment within required specifications.

● Higher torque capacity with optimized compact design

● Excellent rotational and positioning accuracy

● Coaxial input and output

● Commonly used in robotic arm end-effectors or sealed rotary tables
