为了减少由有缺陷的传动系引起的风力涡轮机故障，必须用个位数的千分尺不确定度广泛地确定大齿轮（直径大于或接近1 m）的几何形状的偏差。固定的测量体积限制了标准测量方法，如用于大型齿轮测量的坐标和齿轮测量仪器。为此，提出了一种基于模型的齿轮齿形参数扫描多距离测量方法。该测量方法具有可扩展的设计，包括共焦色传感器，旋转台作为扫描单元和基于模型的信号处理。以一个中型直齿圆柱齿轮为例，验证了基于模型的多距离扫描测量方法的可行性。结果，作为基本齿形参数的平均基圆半径被确定，其不确定性为
To reduce wind turbine failures by defective drive trains, deviations in the geometry of large gears (diameter greater than or similar to 1 m) must be extensively determined with single-digit micrometer uncertainties. Fixed measuring volumes limit standard measuring methods like coordinate and gear measuring instruments for large gear measurements. Therefore, a model-based scanning multi-distance measurement approach for gear shape parameters is presented. The measurement approach has a scalable design and consists of a confocal-chromatic sensor, rotary table as a scanning unit and model-based signal processing. A preliminary study on a midsize spur gear demonstrates the general feasibility of the model-based scanning multi-distance measurement approach. As a result, the mean base circle radius as the fundamental gear shape parameter is determined with an uncertainty of
