In Order To Give Full Play To The Performance Of Harmonic Reducer, Please Pay Attention To The Follo

Make the input shaft, circular spline, output shaft, and shell concentric.

Wave generators can produce axial force. Please make the input shaft into some structure that can support the force.

Since the china harmonic reducer is a small device that can transmit larger torque, please adopt suitable tightening torque to tighten the screw that connects the flex spline with the output shaft.

Flexspilne can have elastic deformation, so please adopt the recommended size to design the inner wall of the shell.

Input shaft and output shaft must adopt matched bearings (leave space for 2 - point support) and the structure that can bear radial load and axial load. Please do not exert too much force on the wave generator and flex spline.

Make sure the flange diameter of the flex spline does not exceed the wheel bore diameter of the flex spline and process fillet on the flange that connects the diaphragm. Please adopt the recommended size to design all parts.

Use a C-shape clamp ring to fix the hub of the wave generator and make sure the hook of the clamp ring does not touch the flex spline or wave generator.

How Do You Calculate The Gear Ratio On A Harmonic Drive?

Calculating the gear ratio on a Harmonic Drive involves understanding the structure and components of the drive. The gear ratio is determined by the number of teeth on the circular spline, flexspline, and wave generator. To calculate it, divide the number of teeth on the circular spline by the number of teeth on the flexspline.
