Can the planet carrier support shaft of the wind power gearbox use full complement cylindrical roller bearings?

The planet carrier support shaft of wind power gearboxes is a critical component that supports the planet gears and transmits torque from the rotor to the generator. 

The full complement cylindrical roller bearings has several advantages:

1.High load capacity: Full complement cylindrical roller bearings have more rolling elements than standard bearings, which allows them to handle higher loads. This is especially important in wind power gearboxes, which operate under heavy loads.

2.Improved stiffness: The increased number of rollers in full complement cylindrical roller bearings provides improved radial stiffness, which is important in applications with high radial loads or shock loads.

3.Reduced friction and wear: With more rolling elements, the load is distributed over a larger area, which reduces friction and wear. This can lead to longer bearing life and reduced maintenance costs.

4.Simplified assembly: Full complement cylindrical roller bearings can be assembled without the use of a separate cage, which makes assembly simpler and reduces the risk of cage failure.

Therefore, the use of full complement cylindrical roller bearings in the planet carrier support shaft of wind power gearboxes is possible but depends on various factors such as the gearbox design, operating conditions, and load requirements.

However, we need to consider some factors when we use the full complement cylindrical roller bearings.​​​​​​​

One critical factor to consider is the load distribution within the gearbox. The planet carrier support shaft of the wind power gearbox experiences a combination of radial and axial loads, and the bearing selected must be capable of handling these loads without premature failure. Full complement cylindrical roller bearings are better suited to handle radial loads than axial loads, and if the axial load is significant, it may be necessary to use a separate thrust bearing.

Another factor to consider is the gearbox operating conditions, such as speed, temperature, and lubrication. Full complement cylindrical roller bearings may not be suitable for high-speed applications, and if the operating temperature is high, it may affect the bearing's performance. Lubrication is also critical, and the bearing must be properly lubricated to ensure adequate performance and longevity.

Overall, proper analysis and consideration of the gearbox design, operating conditions, and load requirements are necessary before selecting the appropriate bearing for the application.
