*1 Overhaul
As a rough indication, perform the overhaul (parts replacement) before reaching 20,000 operation hours of the
Manipulator. The operation hours can be checked in [Controller Status Viewer] dialog - [Motor On Hours].
For details, refer to Maintenance 2.2 Overhaul.
*2 Reduction Gear Unit:
A reduction gear unit consists of the following three parts. When replacing the reduction gear unit, be sure to
replace these parts all together as a set.
Waveform generator
The waveform generator consists of an ellipsoidal
cam and ball bearings on outer circumference.
The inner ring of the 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.
