摘　　要：高速电动机目前被广泛用于汽车自主驾驶系统。由于高速电动机采用小质量设计,因此为了使转速和输出扭矩达到目标值,通常将渐开线齿轮组和它配套使用。然而,传统的渐开线齿轮在工作中噪声较大,因此一种新型的具有不规则轮齿设计的低音调(Low⁃Tone)齿轮被开发,以减少齿轮传动装置的噪声。通过优化算法,开发设计了一种Low⁃Tone齿轮,并应用于一个驱动电动车尾门启闭的电动推杆系统。之后在该系统运行期间,对使用Low⁃Tone齿轮和使用传统齿轮所产生的声压进行测量对比。结果表明,Low⁃Tone齿轮对于噪声有较好的抑制作用,其优势特别体现在音调特性方面。Electric motors with very high speeds are used widely for highly automated and autonomous driving.A low weight design of high-speed electric motors can reduce the demand for environmentally harmful materials.However,due to the regular involute gears,which are usually used with high-speed motors to bring the rotation speed and output torque into target values,a noticeable and extremely annoying tonal noise occurs,which compromises the comfort of passengers significantly.Thus,an innovative low-tone gearing with irregular design of tooth is introduced to reduce the noise of gear transmissions.To obtain a low-tone gearing design for an electric push-rod system,which operates the tailgate of vehicles to either open or close,an optimization is conducted.Then for comparison,the sound pressure of the low-tone gearings and a regular design is measured during the operation of the push-rod system.Finally,the reduction of noise by using the low-tone gearing,especially from the aspect of the tonality,is validated by analyzing the measured data.
