GENERAL DESIGN FEATURES Gear units of the HDP and HDO series make optimum use of advanced design features, to offer: • Top torque density • Superior performance • Silent and vibration-free operation • Total ruggedness and reliability • Lifetime calculation in accordance with the applicable ISO and AGMA standards • Extensive customisation through a wide range of options offered in the catalogue (*) = Refer to the table “Selection of the optimal oil viscosity” for further information about minimum and maximum values of different oil viscosity and for using hydraulic circuits. For values of ta <...

INSTALLATION The following installation instructions must be observed: • Make sure that the gearbox is correctly secured to avoid vibrations. If shocks or overloads are expected, install hydraulic couplings, clutches, torque limiters, etc. • Before the eventual painting, the machined surfaces and the outer face of the oilseals must be protected to prevent paint drying out the rubber and jeopardising the oil-seal function. • Components to be keyed on to the gearbox output shafts should be machined to ISO H7 tolerances to prevent mating surfaces jamming and causing irreparable damage to the gearbox...

LUBRICATION Refer to the User’s Manual available at www.bonfiglioli.com for indications about checking the oil level and its replacement. Do not mix mineral oils with synthetic oils and/or different brands. However, oil level should be checked at regular intervals and topped up as required. Check monthly if unit operates under intermittent duty, more frequently if duty is continuous. 5.1 Selection of the optimal oil viscosity (data relating to Shell Oils) Operating ambient temperature [C° | | Recommended operating limits ; ; Allowed operating limits. © Forbidden operating limits. * = It...

Lubrication for HDP-HDO series gearboxes The internal parts of HDP gearboxes are lubricated with a mixed immersion and splash system. Should the output speed be lower than 1 min-1 or the input speed greater than 1800 min-1, please contact Bonfiglioli Technical Service for advise. In mounting position V5, the top bearings in gearbox sizes HDP 60 to HDP 90 are pre-lubricated with grease and fitted with Nilos seals, unless the order specifies a forced lubrication system with mechanical pump (optional variants OP1, OP2) or electric pump (option MOP). If HDP 100 to 180 gearboxes have to be installed...

STORAGE Observe the following instructions to ensure correct storage of the products: • Do not store outdoors, in areas exposed to weather or with excessive humidity. • Always place boards, wood or other material between the products and the floor. The gearboxes should not have direct contact with the floor. • In case of long-term storage all machined surfaces such as flanges, shafts and couplings must be coated with a suitable rust inhibiting product (Tectile 506 EH or equivalent). Furthermore gear units must be placed with the fill plug in the highest position and filled up with oil. Before...
