Product Details
Design and analysis of rotor bearing for wind turbine In the actual design process, the rotor bearing of wind turbine should be selected and analyzed first, and then implemented with the help of modern CAD technology. (1) selection of rotor bearings for wind turbines The rotary table bearing of wind turbine mainly has four point contact ball, three row roller and cross roller. The two-row four-point contact ball structure has relatively long service life, strong bearing capacity and small rotary resistance, but it has relatively large wear amount and low motion precision. The cross roller structure has relatively high precision and long life. The static bearing capacity of three-row roller structure is relatively high. (2) calculation of the service life of the rotor bearing of wind turbines The service life of the rotor bearing of wind turbine is calculated in practice due to its relatively large size and relatively low rotating speed. In the calculation of the life of the rotor bearing of wind turbines, the bearing capacity curve method and equivalent dynamic load method are mainly adopted. Carrying capacity curve method in the calculation of actual process, to ensure that the specifications of the wheel bearing transformation has a certain bearing capacity, the load and the ratio of the actual load to work out, and then obtain the basic life of wheel bearings, on the life of the wind turbine wheel bearing in the process of solving, is combined with the actual situation of working condition of a comprehensive analysis was carried out on the wheel bearing life. In the actual solving process of equivalent dynamic load method, first of all, the rated dynamic load capacity should be solved, the adjustment coefficient of life and equivalent dynamic load should be determined, and finally, the life of rotary bearing should be calculated. (iii) application of CAD technology
