  • 3. Dow Corning INTERNALThreaded Connections Shrink Disc
  • 4. Dow Corning INTERNAL Threaded Connections Threaded connections in yaw slewing bearing, blade slewing bearing, generator, gearbox, and thread bolts of tower Equipment Application Molykote Feature and benefit Constant coefficient of friction over wide Blades to Hub 1000 range of various steels and protection coatingsThreadedConnections Hub to Tower G-n Plus Low coefficient of friction Dry service coating, used as top coating to Rotor anchor D-321R reduce the coefficient of friction
  • 5. Dow Corning INTERNALApplication Case-Hub• APPLICATION: Molykote 1000 on Bolts. Bolting the Blades to the Hub• COMMENTS : Use of Molykote 1000 ensures correct tensioning of bolts therefore better balancing. Good Corrosion Protection is essential as the Wind Mills are mostly installed near to the coasts. The Weight of each blade is 750 kg.
