Analysis of Tapered roller bearings area

In roller bearings generally operate only part withstand load, while the area where this part of the roller bearing area we call the Tapered roller bearings . The bearing load size, the size of the clearance operation will have an impact on bearing area. If the bearing area is too small, tapered roller bearings the roller in the actual operation is prone to slippage. For the wind turbine gearbox, if the spindle is designed with double Tapered roller bearings support programs, then theoretically only torque is transmitted to the gear box. In this case, after a simple mechanical analysis, we find that the planet carrier supporting the bearing load is relatively small, precision bearings so the load zone of the bearing is often relatively small, roller prone to slipping. In the design of wind turbine gearbox carrier support bearings generally use two single row tapered roller bearings or cylindrical bearing two full programs. We can properly preload tapered roller bearings or cylindrical roller bearings reduce clearance methods to improve the bearing area.
