Posiplan range of gear reducers has been expanded to 12 sizes with peak torque now up to 89,000 Nm, with a ratio range from 13:1 to 10,000:1.

First released in Australia in 2006, the gearbox range manufactured by PIV Posiplan of Italy has found good initial acceptance in the local market, with a number of installations as take up winches used in conveyor drive applications.

The compact design has made the Posiplan range of gear reducers ideal for this type of application, which allows fitting in restricted spaces. Other applications that are ideal for these units include screw conveyors, travel cranes, continuous casting machinery and so on.

A unique hybrid design, which combines planetary with helical gears, or planetary and bevel-helical gears, allows Posiplan range of gear reducers to provide high reliability, with little maintenance.

The Posiplan range of gear reducers also exhibit high efficiency, due to the good quality of the gearing and bearing choices. Efficiencies at greater than 97% for two-stage units are typical, with slightly lower efficiencies for three- and four-stage units.

All Posiplan range of gear reducers come with a torque arm as standard. Optional accessories include shrink discs, common bed frames, backstops, brakes, auxiliary drives and cooling/lubrication systems.

All Posiplan range of gear reducers are shaft-mounted with either a hollow through shaft with keyway, hollow shaft with shrink disc, or splined hollow shaft.

The teeth correction and crowning design guarantee optimum performance under load.

Gleason bevel gears are case hardened, and profile ground or lapped in pairs. Planetary ring-gear is nitride hardened, pinion and planet gears are case hardened with the profile ground for maximum performance and quiet operation.

Posiplan range of gear reducers feature special seals to protect against lubricant leakage and contamination, with labyrinth seals or double seals, with separate grease-filled chamber.

Output hollow shafts are available in cylindrical with key, cylindrical hollow shaft for shrink disc and splined shaft.

PIV Drives is part of the worldwide Brevini Power Transmission Group, of which Brevini Australia is a subsidiary.
