Assembly Of Belt Drive Rt80; Tightening Belt Drive Rt80 - THOMSON WIESEL FORCELine Instructions De Montage Et De Maintenance

Mechanical Linear Drive Unit WIESEL FORCELine
Assembly of Belt Drive RT80 (only MLSM 60 KGT)
1. Fig. 7: Attach WIESEL
to housing (1).
2. Press ball bearings (2 and 3) onto synchronous spro-
ckets (4 and 5).
3. Push the synchronous sprockets (4 and 5) with
DKWN tension sets (6 and 7) onto profiles of motor
®
and WIESEL linear drive unit, and clamp them.
Tightening torque for screws on DKWN tension set
depends on inside diameter (see table in Chapter 10
"Technical Data"). Distance between top of housing
and synchronous sprocket: 5 or 3mm (see Fig. 10).
4. Insert toothed belt (8).
5. Insert tensioning roller (9) in housing, and fix with
screw (10) and washer (11).
