SGS supplies gears for coal crushers to Russia

SGS Sonder Getriebe Service GmbH has supplied gears for two double roll sizers (DRS) for use in Russia. The gears are designed for high impact loads and at the same time they must resist temperature fluctuations between -40 °C and +40 °C. For this purpose, the gears are heated, the lubrication system is optimized and materials with subzero toughness, which fulfil the required impact work without any problems at -40 °C, are employed. The construction of the gears comprises spur gears including fluid couplings with elastic, vibration-damped couplings, contact-free thermal shifting devices and curved teeth couplings on the output side designed according to the requirements. The drive units for the double roll sizer DRS 2000 weighs 8000 kg, the two drive units for the double roll sizer DRS 1500 weigh 1200 kg each (Fig.).
