*1 Reduction Gear Unit
A reduction gear unit consists of the following three parts. When replacing the reduction gear unit, be sure
to always replace the waveform generator, flexspline, and circular spline all together as one set.
Waveform generator
This waveform generator consists of an ellipsoidal cam with ball
bearings on its outer circumference.
The inner ring of bearings is secured to the cam, while the outer ring
is capable of flexible deformation through the ball bearings.
Flexspline
A thin, elastic, cup-shaped metal body with gear teeth around the
outer circumference of the opening.
Circular spline
A rigid, ring-shaped body with gear teeth on the inner
circumference.
The circular spline has two more teeth than the flexspline does.
Splines are greased. Be careful not to let grease adhere to clothes.
