- Use bolts of grade 8.8 or greater to secure the gearbox. Tighten the bolts to the rated valuesspecified in the relevant charts.With transmitted torque greater than or equal to 70% of the given « T 2max », and with frequentreversals, use bolts with minimum grade 10.9.Some gearboxes can be fastened using both bolts and pins. If a pin is used, the portion of thepin inserted into the equipment the gearbox is being installed to should be at least 1.5 timesits diameter.b) Connections- When fitting transmission elements onto the input or output shaft do not tap them with hammersor similar tools. To slide these parts in, use the service screws and taps provided at theshaft ends.Be sure to clean off any grease or rust preventative from the shafts before fitting any parts.- Direction of rotationBefore wiring the motor please note the input/output shaft arrangement, as described in thediagram here after:(A9)In lineCombined worm/planetary gear unitRight angleCombined bevel-helical/planetarygear unitc) Paint coating- Use paint compatible with the primer applied to the gearbox, see: Conditions of supply.Prior to painting, tape the seal rings installed on the shafts.Contact with the solvent may deteriorate the seals with subsequent oil leakage.d) Lubrication- Prior to commissioning, fill the gearbox with the recommended type and quantity of oil (see:Lubrication).The level is to be checked through the appropriate plug, each gearbox is provided with, andlocated according to the mounting position originally specified.NOTE: Combined gearboxes feature separate lubrication for planetary stages and for worm gears(series 3/V) or bevel helical units (series 3/A).The operations described above are not to be performed with life-lubed gearboxes, that are factoryfilled with synthetic oil (see tab. A25).18
