The Requirement

We were approached for an urgent need to refurbish a double drum shaft sink kibble winch in the mining sector. The functional design layout made it necessary to keep the existing distance between the output shaft and input shaft to just over 2.7 meters.
Our task was to maintain the center distance between input and output shafts, conserve the total gearbox ratio of the existing design, and improve gearbox reliability, thereby reducing maintenance requirements.

our solutions

The original gearbox layout used a bevel helical main gearbox with another bevel gearbox connected to the input shaft, while our solution used an NBE extended center gearbox providing the exact same ratio as the previous design and keeping within 1 mm of the original center distance between shafts.

The only effective way to respond to each requirement was to conceive a fully customized product. Our single gearbox solution replaced the two gearboxes that regularly required alignment of the flexible coupling. The NBE80 was equipped with bearing temperature and vibration monitoring on each bearing and a forced lubrication system provided filtered oil to each bearing.

Working with the Dana team in Bad Homburg, Germany, we were able to offer a custom-built gearbox meeting the stated requirements:

  • equivalent ratio to previous design
  • shaft center distance compatibility with previous design
  • reduced maintenance needs compared to previous design
  • increased reliability through
    – vibration and temperature monitoring
    – filtered forced lubrification
