The establishment of gear fault data warehouse the paper studies several gear cases in drive lab of wuhan university of science and technology. the signal of normal gear pair, the one has been worn seriously, the one which has circular pitch error and the one whose pinion has a ruptured tooth is acquired independently. after fft transformation, the amplitude values of 0 - 0. 4 multiple engage frequency, 0. 4 - 0. 5 multiple engage frequency, 0. 5 - 1 multiple engage frequency, 1 multiple engage frequency, 2 multiple engage frequency, 3 multiple engage frequency, 4 multiple engage frequency and greater then 4 multiple engage frequency of every signal are obtained respectively
論文主要完成下列內容: 1 .齒輪故障數據倉庫的建立以武漢科技大學傳動實驗室的若干臺齒輪箱為研究對象,分別採集正常齒輪副、磨損嚴重的齒輪副、有周節誤差的齒輪副和小齒輪有一個斷齒的齒輪副的振動加速度信號,經過fft變換,分別得到每個信號的0 ~ 0 . 4倍嚙合頻率、 0 . 4 ~ 0 . 5倍嚙合頻率、 0 . 5 ~ 1倍嚙合頻率、 1倍嚙合頻率、 2倍嚙合頻率、 3倍嚙合頻率、 4倍嚙合頻率和大於4倍嚙合頻率幅值。 -
We have advanced production lines and test equipment. we can make ffc with pitch from 0. 3mm to 2. 54mm. ffc working voltage is from 30v t0 300v, and working temperature is from 80 to 105. we not only can make normal ffc, but also make cable for air - bag for cars. we also can help clients to do contacts and housing assemblies. 1. 27mm and 2. 54mm contacts are available
