Siemens SINAMICS G115D Operating Instructions Manual page 427

Procedure
1. Attach the torque arm ⑦ to the gearbox, see Torque arms with slip-on gearboxes
(Page 427).
2. Remove the corrosion protection coating using white spirit or a solvent on:
– The shaft ends of the machine shaft ①
– The clamping ring ③
– The bronze bushing ②.
3. Check the seats or edges of the hollow shaft ⑥ and the machine shaft ① for damage. Please
contact Technical Support if you notice any damage.
4. Place the clamping ring ③ on the bronze bushing ②.
5. Position the bronze bushing ② with the clamping ring ③ on the machine shaft ①. Observe
the tightening torque of the tightening bolt ④ and the tolerance dimension to10.
6. Oil lightly the locating holes in the hollow shaft ⑥ for the tapered bushing ⑨ and bronze
bushing ②. Remove any excessive oil using a clean cloth.
7. Push the gearbox with the installed torque arm ⑦ on the machine shaft ① against the
clamping ring ③.
8. Tighten the torque arm ⑦ with the bolts ⑧ only gently because the gearbox must have
clearance for the subsequent mounting.
9. Ensure that the thrust collar⑨ is placed at the correct position.
If the thrust collar ⑤ is not placed at the correct position, bring the ring ⑤ into the correct
position by tightening the tightening bolts ⑩ with turned tapered bushing ⑨.
10.Place the tapered bushing ⑨ on the machine shaft ①.
11.Use the torque wrench to turn each of the tightening bolts ⑩ equally (not crosswise),
repeating this procedure several times. Observe the tightening torque of the tightening
bolt ⑩.
12.Tighten the bolts ⑧ of the torque-arm fastening, see Torque arms with slip-on gearboxes
(Page 427).
13.Attach the rubber cover or protection cover ⑪ included in the scope of delivery, see
Removing and installing the protection cover (Page 414).
