摘要

摘要。节距轴承对风力涡轮机的安全、高效运行至关重要。它们将转子叶片连接到转子轮毂,并允许俯仰运动来控制负载和转子速度。虽然四点接触球轴承在过去一直占主导地位,但由于在相同直径下具有更高的负载能力,三列滚子轴承在当前设计中越来越多地使用。滚道磨损是节距轴承可能的损伤机制之一。由于滚子轴承与以前的设计有很大不同,并且风力涡轮机的运行条件与其他工业应用不同,因此在此类轴承调试之前进行磨损测试是一种合理的降低风险的做法。本研究概述了基于气动弹性模拟数据和风速测量的磨损测试程序的开发过程。然后将该过程应用于示例滚子轴承。最后的程序包括静止状态和俯仰周期。第一种方法是对前几种方法的主要补充。有了现有的测试设备和合理的预算和时间表,该计划可以执行。

Wear test programs for roller-type pitch bearings of wind turbines
Abstract. Pitch bearings are critical for the safe and efficient operation of wind turbines. They connect the rotor blades to the rotor hub and allow for pitching movements that control loads and rotor speeds. While four-point-contact ball bearings have been dominant in the past, three-row roller bearings are increasingly used in current designs due to their higher load capacity at the same diameter. Wear of the raceways is one of the possible damage mechanisms in pitch bearings. As roller bearings differ significantly from previous designs and because the operational conditions of wind turbines differ from other industrial applications, it is a reasonable de-risking exercise to undergo wear tests prior to the commissioning of such bearings. This study outlines a process for developing a wear test program based on aero-elastic simulation data and wind speed measurements. The process is then applied to an example roller bearing. The final program covers both standstill conditions and pitch cycles. The first is the main addition to former approaches. With existing test rigs and a reasonable budget and timeline, the program can be executed.
