After the successful completion of the main gearbox sliding bearing test for the 6MW semi-direct drive model and the achievement of milestones, Changsheng Bearing has continued to push forward the relevant work in an orderly manner and has recently obtained the wind power main gearbox sliding bearing order from the mainframe. After the delivery of the relevant products, the main gearbox with sliding bearings will soon be installed into the wind turbine by the mainframe plant for hook-up tests.

 

 

 

 

Changsheng Bearing cooperated with the host manufacturer to build the first 1:1 scale main gearbox sliding bearing test rig in China, which simulates the rotation of planetary gears relative to planetary pins, and successfully completed the main gearbox sliding bearing test for 6MW semi-direct drive models. At the same time, it has laid a solid technical foundation for the development and mass production of main gearbox sliding bearings for subsequent higher power models.

 

 

 

Wind power main gearbox planetary gear bearings with sliding bearings instead of rolling bearings can greatly improve the torque density of the main gearbox, at present, the torque density of the main gearbox with sliding bearings has reached 220Nm/kg, making the structure of the main gearbox more compact. Compared with rolling bearings, the bearing capacity of sliding bearings is greater, sliding bearing oil film has good vibration absorption and impact resistance, sliding bearing structure is simple and the price has obvious advantages, therefore, under the double drive of technology and cost, the future wind power main gearbox planetary gear bearings by sliding bearings instead of rolling bearings is an inevitable trend.

Committed to becoming a global strategic partner for high-performance tribology and polymers, Changsheng Bearings will actively provide customized solutions for wind and nuclear energy and other clean energy sectors, helping to achieve the "double carbon" goal and contributing to the care of the earth.
