摘要

行星轮轴承是风电齿轮箱的关键部件，因其位置的特殊性和受载的复杂性，在风电齿轮箱的设计开发过程中，如何准确分析行星轮轴承的载荷作用中心往往成为设计难点。根据当前风电齿轮箱的设计规范，在10 MW负荷试验台上，对两台3 MW风电齿轮箱进行背靠背测试，试验中对行星级齿轮进行了应变测试。以此次测试的输入级行星轮轴承为例，基于齿轮的应变测试结果，进一步挖掘应变测试数据的应用，使用最小二乘法原理，给出了确定行星轮轴承载荷作用中心的精确方法。

Abstract

The planetary bearing is one of the most important components for wind turbine gearboxes

due to the complication of the load and the special position. How to analyze the load center becomes the critical job for design engineers. Based on current design specifications

two 3 MW gearboxes with back to back arrangement are tested on the 10 MW testing benches

and strain testing is conducted on planetary gears during the experiment. For further utilization of these testing results about the strain of the gear

the least square method is taken to precisely estimate the load position of the applied center for the planetary bearings during the development for the new wind turbine gearbox.
