Lubrication
6
The gear pairs and the bearings are oil bathed, splashed or lubricated «for life» with grease (with or without NILOS ring).
Unless otherwise stated, gearmotors are supplied
FILLED WITH POLYGLYCOL BASIS SYNTHETIC OIL
(KLÜBER Klübersynth
GH 6-220, MOBIL Glygoyle 220, SHELL Omala S4 WE 220), providing lubrication – assuming pollution-free surroundings – “for
life”.
We recommend that you check the oil level; each gear reducer is equipped with a lubrication plate.
For lubricant type, gear reducer delivery condition, plugs, fi lling instructions, lubrication intervals, etc., see ch. 6.2 and 6.3.
Attention!
Ensure that the gear reducer is complete with oil and (metal) breather plug mounted in the correct position as per
required mounting position; for BX mounting positions, it is supplied loose and must be mounted in the position
corresponding to the desired mounting position.
The breather plug must be activated prior to commissioning by removing the tab provided (see fi g. 6.1.1).
It is necessary to keep the breather free from dirt that could compromise its functionality.
If this is not possible, please contact Rossi S.p.A. to fi nd a diff erent solution
The lubricant quantity to add shall be the one that will allow you
to reach the required level, shown in the middle of the plug
,
with the gear reducer not running, and not the indicative quantity mentioned in the catalog.
Fig. 6.1.1 Activating the breather
The bearings are normally automatically and continuously lubricated (oil bath, splash method) by the gear reducer lubricant or by
"lifetime" grease with or without a metal shield.
For gear reducers in vertical V6 mounting position, the upper bearings are independently lubricated with special grease for
"lifetime" lubrication, if no external pollution is present
(the outer bearing on the low speed shaft is always grease lubricated).
Make sure that the gear reducer is fi tted according to the mounting position specifi ed in the order - including inclined
mounting positions (e.g. B3 38° V5) - as indicated on the name plate (see ch. 3.2).
For mounting positions, oil quantity and plug position, see ch. 6.3 and 6.4.
