A Review of Feature Extraction Methods in Vibration-Based

Since slew bearing operating at very low speed with highly applied load, the vibration signals exhibit non-linear, non-stationary and chaotic behaviour. The methods such as impulse factor and margin factor measured the statistical properties of vibration signal and therefore could revealed the information related to the impulse level.

Fatigue life analysis of slewing bearings in wind turbines

Jun 01, 2018· Slewing bearings are important components of wind turbines and composed of a yaw bearing and a pitch bearing. They have driving teeth in the inner or outer ring that drive the pinion gear and transmit torque to achieve the wind turbine yaw and pitch movement, as shown in Fig. 1.The common yaw bearing is a four-point contact ball slewing bearing with a zero cross …

- The Latest in Slewing Ring Bearing Technology

Sliding slewing ring bearings have excellent vibration-dampening ability. When tested, our PRT slewing ring bearings outperformed roller bearings in atmospheric conditions at 5G’s. The vibration caused the balls in the roller bearing to fly out, while the sliding slewing bearing absorbed the vibration and remained completely intact. Temperature.
