6.2.2. Vertical shaft installation
The target range for filling the lubricant (the
areas in the diagram) inside the reduction gear when
the reduction gear is installed in the vertical shaft is indicated below. The amount does not include the
space (the
areas in the diagram) on the motor mounting side. Therefore, if there is a blank space,
also fill the space. Leave a space about 10% of the total volume of the internal capacity of the reduction
gear (the
areas in the diagram) and the space on the motor mounting side (the
areas in the
diagram). Be sure to fill the amount of lubricant described in the separately provided “Outer dimensions”
drawings. If there is no indication in the “Outer dimensions” drawings, contact our service representative
individually.
Fig. 6-2
Be sure to leave a space about 10% of the total volume. If overfilled, the temperature increases
during operation and the internal pressure also increases. As a result, oil seals could fall off or
lubricant could leak.
If the lubricant is not filled sufficiently, it could lead to premature damage of the reduction gear.
The shape of the reduction gear may differ from the illustration in Fig. 6-2 above, depending on the
ordered specifications. For details on the shape, refer to the separately provided “Outer dimensions”
drawings and specification sheet.
