300 series - Planetary drives

New product

The best solution to all situations when heavy duty needs high power

The series 300 gearboxes are extremely compact, but even though they develop a high specific power. The planetary gears are the ideal solution for all applications but above all for the severest ones, that is to say when bumps and overload are a standard condition rather than an exception. The product configuration is extremely versatile thanks to various options available for the type of fixing, the physical disposition of the reductions, the hollow shaft and the motor interface. All these features can be found in each one of the 18 versions that cover the range of transmissible torque from 1.000 to 1.100.000 Nm. Finding the ideal solution for any transmission problem is therefore more than a desire, it's something on which the end users can steadily count on - always.

CONSTRUCTION:

Gears

  • Case hardened high tensile alloy steel gears
  • Ring gear induction hardened
  • Tooth profiles optimized to gain maximum root strength and minimize sliding contact to ensure high efficiency
  • All external tooth profiles shaved
  • Planet gears have an elliptically crowned tooth profile to give ideal loading along the teeth. The gears rotate on needle rollers mounted on case hardened pins.

Planetary carriers

High quality cast iron for strength and rigidity to ensure equal tooth loading in the planetary gearing.

Shafts

Case hardened high tensile alloy steel is resistant to bending and torsional stresses to maintain proper support and alignment of all gears even under the most critical loading conditions.

Housings

Gearbox casing of nodular cast iron for strength and rigidity.

Steel housings are also available on request.
