一种风电增速箱用圆锥滚子轴承的减摩设计

Antifriction design of a kind of tapered roller bearing for speed-up gear box of wind-driven generator

为了提高风电增速箱中圆锥滚子轴承的寿命,降低轴承在高速运转时各部件之间的摩擦,对圆锥滚子轴承的滚子球基面和内圈挡边接触形式进行了优化减摩设计,改善了滚子球基面和内圈挡边运转时的润滑条件,减少了摩擦热,提高了轴承的使用寿命。

In order to improve the life of tapered roller bearing in speed-up gear box of wind-driven generator and reduce friction between components during high speed running of bearings, the optimum antifriction design of the contact form between the roller spherical fiducial surface and the inner ring rib of tapered roller bearing is made to improve the lubrication conditions between the roller spherical fiducial surface and the inner ring rib during running, reduce the friction heat and improve the service life of the bearing .
