Connecting reducer to driven shaft

Figure. Attachment Using a Spacer and Retaining Ring
(Customers need to provide their own spacer, bolts, and retaining rings.)
Note) Be careful when tightening the bolt, as tightening it too much can distort the shape of the retaining ring.
Coat the driven shaft surface and interior surface of hollow shaft with a lubricant (molybdenum disulfide)
suitable to the atmosphere in which they are used and connect the reducer to the driven shaft.
When used with uniform loads, a driven shaft tolerance of h7 is recommended. Additionally, when
dealing with impact loads or large radial loads, make sure they fit each other tightly. The tolerance of
the interior surface of hollow shaft is designed to be H8.
4-3. Installing/Removing FS/F3S Type Hollow Shaft
If the shafts are a tight fit, use a plastic hammer on the end of the hollow shaft to insert it. When doing
so, be sure not to hit the casing. If you make a jig like the one in the diagram below, driven shaft
insertion will be easier.
It is recommended that axial runout for the shaft be 0.05 mm or less at the shaft end. If major wobbling
occurs during operation, it may have a negative effect on the reducer.
For the length of the turn-stop key for the driven shaft, tolerance range H8 for the internal diameter on the
fixed side is recommended.
