变速箱振动谱很复杂，并且充满了伪影，使得眼睛很难记录由于故障而产生的变化。为了克服这一困难，本文提出了一种齿轮箱的状态指标，它可以趋势。齿轮箱状态指示器基于齿轮啮合频率的前三个谐波周围的边带电平的总和。建议的齿轮箱状态指示器损坏的敏感性进行了研究，使用播种不适当的间隙下的一系列操作条件。
The gearbox vibration spectrum is complicated and overloaded with artefacts, making it difficult for the eye to register a change due to a fault. In order to overcome this difficulty this paper presents a gearbox condition indicator, which can be trended. The gearbox condition indicator is based on the summation of the sideband levels around the first three harmonics of the gear mesh frequency. The sensitivity of the proposed gearbox condition indicator to damage is investigated using seeded improper backlash under a range of operational conditions.
