Sun Gear Bearings
The sun gear is the central component of a planetary gearbox. It operates at high speeds and under significant loads, receiving forces from all planetary gears. Sun gear bearings must ensure high precision and reliability.
Loads
- Radial forces from meshing with planetary gears
- Axial forces from helical gear meshing
- High rotational speed
- Vibration from the planetary mechanism
Solutions
Precision cylindrical roller bearings and angular contact ball bearings are used. Preloaded bearings are employed to increase rigidity. It is recommended to use bearings with heat-resistant lubricants for high-speed operation modes.
