Sumitomo Drive Technologies TAPER-GRIP ST Installation And Maintenance

Note: Satisfactory performance depends on proper installation.
Therefore all instructions on this leaflet must be carefully followed.
1. Check the size and condition of the shaft to which the reducer will be fitted. Maximum tolerance is h11
although this should be improved upon where possible. Ensure the shaft and Taper-Grip® Bush bore
are free from burrs and corrosion. Clean both bore and shaft with solvent to remove all traces of grease
and oil.
2. Lightly oil the screws and insert into the Taper-Grip
face.
3. Fit the thrust collar onto the Taper-Grip® Bush, ensuring it is located on the spigot immediately behind
the flange. Screw the Taper-Grip
trapped between the flange and the reducer hub.
4. Unscrew the bush until a gap of approx. 1 mm is seen between the flange and the thrust collar (see
diagram). Tighten all screws until they are finger tight. On reducers with a keyslot on the end of the hub,
ensure that a screw is NOT positioned over the keyslot.
5. Slide the reducer onto the shaft at least as far as the counter bore, if present, in the Taper-Grip® Bush.
Gradually tighten each screw in turn to the torque levels shown below. If the shaft has passed through
the counter bore, grease fill the cavity at the shaft end to prevent the build up of corrosion. Installation
details of V-drive, torque arm, etc. are given in the leaflet provided with each gear unit.
6. After the reducer has been running for 20 or 30 hours, re-torque the screws to the values in the table
below.
Screw torques should be subsequently checked at normal service intervals (i.e. every 6 months).

REMOVING THE REDUCER FROM THE SHAFT

Slacken each screw gradually until they are free from the thrust collar. Give the Taper-Grip
tap with a mallet to break the taper, this will free the reducer. Finger tighten two of the screws against the
thrust collar to prevent the Taper-Grip
from the shaft.
