Application Handbook

The relative perpendicularity and concentricity of the three basic gear elements have an important influence on accuracy and service life. Misalignments may adversely affect performance and reliability. Compliance with recommended assembly tolerances is essential in order for the advantages of the gear to be fully exploited.

Careful attention should be paid to the following points:

1. Input Shaft, Circular Spline, and housing must be concentric.
2. The oil drain also enables assembly verification.
3. The Flexspline pilot diameter must be concentric to Circular Spline.
4. A clamping ring with corner radius increases torque transmission capacity and prevents damage to the Flexspline diaphragm.
5. A radial shaft seal for oil lubrication.
6. Double bearing support for output shaft.
7. Axial location of Flexspline.
8. Air vent depending on the application.
9. Flexspline and Circular Spline must be located both parallel and perpendicular to the output shaft.
10. Axial location of Wave Generator.
11. Oil input. (also enables assemble verification)
12. Double bearing support for input shaft.
