Planetary Gearbox

INTRODUCTION:
The BIGNOZZI Range of planetary gearboxes are built for the most severe power transmission requirements in the highest demanding applications. Among the many industries we service are the following: - earth moving machinery, road construction equipment, forestry, agricultural and plastic machines. The modular design construction allows for maximum interchangeability of standard components. - concentric shaft design, with input & output shaft rotating in the same direction regardless of the reduction stages:
Type Production Ratio 
Sigle  from 3.5 to 7.25 :1
Double from 12 to
43
 :1
Triple from 46 to 305 :1
Consulting factory for higher ratios.
Output torque range from 100 daNm (740 ft-lbs) to 6000 daNm (45000 ft-lbs). Special design to 26000 daNm (200000 ft-lbs).
All gearboxes are arranged to accept different input drives from either direct mounted hydraulic or electric motor, or by power take-off with shaft connection.
Solid male output shaft (cylindrical with key or spline) to support high radial and axial loads. Hollow female spline connections for compact torque transmission only.
A variety of accessories components:
Foot mounting brackets.
Fail safe multi-disc brakes
Backstop to prevent reversing rotation
Primary bevel gear for right angle input design
Shaft connectors-spline coupling, wheel flange, spline rods. pinion gear for slew drive.
Planetary Advantage
High shock load resistance
High torque low speed capabilities
Load reversals
Compact design
CONSTRUCTION:
Gears
- Made from case hardened and tempered steel forgings;
- Ring gear is hardened and tempered steel;
- Gear tooth are designed to give an optimum balance between tooth beam strength and maximum durability rating based on the dimensions of the gear set;
- The planet gears are crown shaved to give an optimum loading along the teeth face.

Planetary carriers
- High quality cast iron for maximum strength and rigidity, to ensure equal tooth loading of the planetary gearing.

Shaft
- Made from case hardened tensile alloy steel, higher resistant to bending and torsion stresses and to maintain rigid support and alignment of all gears even under the most critical loading conditions.

Housings
- The gearbox casing is of high duty cast iron for strength and rigidity against shock loading.
