摘要
由于船用齿轮箱的特殊使用工况,其性能要求远远高于其他齿轮箱。分析了某大功率船用齿轮箱的结构和传动原理,并在大功率齿轮传动试验台上进行试验测试。通过对振动信号FFT分析,发现其振动主要由输入级、中间传动级、输出级的啮合频率及其倍频引起。该大功率船用齿轮箱振动烈度达到4.47mm/s,最大结构噪声131.27dB,对应输出级啮合频率329Hz处。
The performance requirements of marine gear box are much higher 1 due to its special working conditions. The structure and transmission principle box are analyzed, and the experimental test is carried out for the analysis an characteristics and intensity. Measured by FFT analysis of vibration signals, t octave and the engagement frequency of input stage and middle-class transmissi high-power marine gearbox reached 4.47 mm/s. In addition, the calculated structure noise of the measur ing points is at the 1/3 octaves, and the largest structure noise is 131.27 dB which occurred in the frequen cy of 329 Hz.
