Reduction Gear Unit
A reduction gear unit consists of the following three parts (for Joint #1 and Joint #2). 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.
The splines are greased. Be sure to keep the grease from being attaching to the clothes.
