Operating position

The required grease quantity is dependent on the gear size and the operating position. The following operating positions
“Wave Generator above” or “Wave Generator below” refer to the position of the Wave Generator in relative to the Flexspline
flange, see illustration 39.2.

Operation mainly with Wave Generator in vertical position or below

The standard grease quantity defined in table 38.1 is calculated for operating mainly with Wave Generator in vertical position or
below.

Operation mainly with Wave Generator above

If the gear is mainly operated with Wave Generator above, additional grease must be supplied above the Wave Generator, see
illustration 39.3 and table 38.1.

Illustration 39.3

If the gear is used mainly with
Wave Generator above, then
additional grease lubrication
is necessary.
