8.1 General
8.2 Lubrication
All mounting bolts must be retightened after a short period of operation.
The wear of the lifting screw nut (worm gear) must be checked after approx. 200 hours of
operation (sooner if operating conditions are harsh).
The lifting screw nut must be replaced when the axial backlash with a single-start thread
is more than ¼ of the thread pitch.
Fig. 14: Lubricating nipple
N/V-version:
At 30-50 operating hours after initial operation, then every 200-300 operating hours,
The worm gear screw jack must be lubricated at the grease nipples (see picture 14).
R-version:
Lubrication of gear box every 700 operat-ing hours.
R-version screw
R-version screw is not lubricated due to assembly reasons.
For lubrication of R-version screw we recommend:
gleitmo 805, gleitmo 585M, Fa. Fuchs Lubritech GmbH
For R-TGS:
lubricate well
For R-KGS:
Too much lubricant increases the friction and there-with the temperature.
The amount of lubricant is sufficient when a slight fettoutlet can be seen at the seal lips.
Standard grease
Alternate greases
Castrol Spheerol BM2
Lithogrease G421,
Fa. Gmehlin
Mobil Mobilgrease XHP
Tightening torque of the screws for bearing lids depends on the gear model (see table
in section 9.3 "Tightening torques").
