Function of the Main Taper Roller Bearings:

• Machine weight

• Travel forces in wheeled and crawler vehicles / Chain tightening forces

• Reaction forces from hydraulic working cylinders, e.g. in excavator applications

• Rope forces in winch applications

• Pull-/ Push- forces in dozer applications

• Drilling- & Cutting forces in drill-riggs, trenchers- or road - cutters

Advantage of Taper Roller Bearing versus Ball Bearings

• Line contact of rollers versus Point contact in ball bearings gives low-level specific pressure

• Unexpected shock- or overloads create less damage from over-pressure compared to ball bearing




Grinding Process (Sun / Planetary Gears)• Grinding on planetary- and sungears after hardening• Grinding includes evolute profile, tooth root & bearing race for planet roller bearing• All deformations from heat treatment process/quenching are 100 % taken away from gear• Gear root fatigue life is improved due to smooth shape and perfect surface roughness

Gear

Sungear Planetgear 1 Planetgear 2 Pinion - Sungear




Process:

• Ringgear material is forged IQT- steel, typically 42CrMo4V

• Part is keept in a Nitrogen atmosphere at 480 °C / 80h duration

• Nitrogen diffusion into material creates hardness-values of 60 HRC without need for quenching

Benefit:

• Low process temperature and missing of quenching minimizes gear deformations

• High accuracy (Carraro drives use up to 7 planetaries are used ) guarantees even load distribution

Nitrating Ring Gears




Gear-Grinding & Nitrading - Benefits

• Gear grinding and nitriding creates high accuracy for the gear - meshing contact

• Carraro planetary drives use up to 7 planet gears

• High accuracy guarantees even load distribution

• Measurement tests in 5 - planet carrier system showed differences < 3 %

T1

T2

• T = 100 %

• T = T1+T2+T3+T4+T5

• Tmax / Tmin < 3 %
