Bronze bushings for wind turbine gearboxes
The main function of the gearbox of a wind turbine is to convert the low-speed operating input of the main shaft into the required output of a medium or high-speed generator.
Due to the harsh installation environment: such as mountains, wilderness, beaches, islands, etc. Therefore, the reliability and service life of various accessories including oil seals and floating oil distribution rings are very demanding.
The gearbox copper oil seal and floating oil ring, whose copper ring is mainly made of tin bronze CuSn10P1: has high hardness, good wear resistance, and good corrosion resistance in the atmosphere and fresh water.
