• Abstract:There are a series of advantages about the double involute gear with ladder shape of tooth. But whether the ladder-shaped of the double involute gear will cause the increase of the vibration or bring some other vibration components? This problem is especially concerned by people all the while. The essence of wavelet packet analysis is to make further decomposition of wavelet decomposed result, so the analysis will yield much better frequency localization. Duo to wavelet packet has agile and changeful characteristics in disposing signals, it can be used to analyzed and compared the vibration characteristics of common involute gear and double involute gear conveniently and exactly by decomposing and reconstructing signal components of correlative frequency components. The result shows that the double involute gear has lower noise, smaller vibration and better dynamics characteristic than common inlovute gear.
