Direct Motor Connection Flange Harmonic Reduction Gear

● Introduction

The LCSG-RDB harmonic reduction gear series is designed based on the FSG-I platform to facilitate direct motor connection for customers. It features pre-designed motor shaft connection holes and motor mounting flanges, with the gear reducer internally sealed with special lubricating grease at the factory. This series typically employs a fixed circular spline end and an output flexspline end directly coupled to the motor during operation. It provides exceptional convenience for applications requiring direct motor connection and custom sealing flanges - customers can simply secure the motor connection with screws for immediate use after procurement. This design streamlines integration while maintaining sealing integrity for users with direct-drive requirements.

Features

● Features a sealed flange and pre-machined motor shaft connection holes based on the FSG series design

● Greatly simplifies customer installation by eliminating the need for custom flange fabrication

● Delivers excellent rotational and positional accuracy

● Coaxial input and output configuration
