The locator bearing combines a single-row tapered roller bearing with a secondary rib ring and is an ideal substitute for a cross locating single-row arrangement, a double-row arrangement or a combined four-point contact ball and cylindrical roller bearing.
This design requires less axial space, improves output shaft efficiency and enhances the performance of the wind turbine’s output system.
Design Attributes:
- Offers reduced axial space due to single-row configuration, which results in a narrower design that also decreases the required length and weight of the heavy gearbox housing.
- Provides great adaptability to existing gearbox designs.
- Allows for improved gear contact positioning due to the centering characteristic of the bearing operating within a 360° load zone.
- 360° load zone reduces stress and increases bearing life.
- More compact design offers reduced system cost.
- Design optimizes race/roller contact angle to keep the bearing seated.
- Smaller out flange is available on wither end of the outer race to prevent the possibility of reversing orientation during assembly.
Applications:
- Wind turbine gearbox high-speed output and intermediate shafts
