Correct assembly of component sets may be checked in one of four ways:
Illustration 39.1
• By visual observation, if the tooth mesh is exposed.
• In case the gearing is not visible, the input shaft can be rotated by hand. Uneven rotation suggests dedoidal tooth mesh.
• If the Wave Generator is connected to a motor, an unusually high motor current indicates dedoidal tooth mesh.
• A dial gauge can be inserted through an access hole near the Circular Spline to touch the surface of the Flexspline. A
quasi sinusoidal deflection during one revolution of the Flexspline indicates correct assembly as shown in illustration 39.1.
