High Rigidity High torque High Precision Strain Wave Drive

● Introduction

The FHG-II series strain wave drive features a cross roller bearing coupling structure for its wave generator, allowing for automatic fine-tuning of coaxiality. The size of the cam shaft hole can be adjusted according to the customer's motor model, with the input shaft directly fitting into the inner bore of the wave generator and connected via a flat key. It incorporates a built-in high-rigidity cross roller bearing (main bearing). Generally, it is used with the rigid wheel end fixed and the flexspline end output, or with the flexspline fixed and the rigid wheel end output as the connection method.

Features

● The wave generator with a cross roller bearing coupling structure is easier to install.

● Excellent rotational accuracy and positioning accuracy.

● High torque capacity.

● High rigidity.

● Input and output are coaxial.
