Top drive with EC-gearing ( Extraction and processing of raw materials )




The proposal to potential partners, investors and just interested parties

Our company has developed a promising solution to the use of EC-gearing in the Top gear drive for drilling rigs. This solution has several competitive advantages:

  • Reducing the number of stages in the gearbox from two to one, which will reduce the cost of gear and reduce the probability of a possible failure of the system;
  • Increasing the thickness of the tooth will raise the overloading characteristics of the drive and increase the longevity of his work;
  • Reducing the axial dimensions of the drive will reduce the manufacturing cost of the drive as a whole;
  • EC-gearing requires a smaller amount of lubricant that will positively affect the performance at low temperatures;
  • The new tooth profile reduces losses within the drive.
