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 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.
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. This ratio represents the speed reduction or multiplication achieved by the Harmonic Drive. It's important to note that the gear ratio can be further influenced by the specific design and configuration of the Harmonic Drive.
The transmission ratio of a Harmonic Drive, also known as the gear ratio or reduction ratio, is determined by the number of teeth on the circular spline, flexspline, and wave generator. The gear ratio represents the speed reduction or multiplication achieved by the Harmonic Drive. In a typical Harmonic Drive, the gear ratio can range from 30:1 to 320:1, or even higher in specialized versions. This means that for every rotation of the input shaft, the output shaft rotates a certain number of times determined by the gear ratio. The specific gear ratio of a Harmonic Drive depends on the configuration and specifications of the particular model, we have model for harmonic gear reducer, check for more information with this link.
