这篇论文是关于高速直齿轮噪声与振动特性的试验研究.齿轮的噪声与振动受齿轮系统各种因素的影响是复杂的,要弄清楚其特性必须系统地分析各种因素之间的相互关系.在这项研究中、齿宽和齿轮的运行条件是变化的,试验是在功率吸收型高速齿轮试验台上进行,运行转速3000-13000转/分.这项研究中所用的试验齿轮,其模数为3,压力角为20°,齿数比Z_1/Z_2为35/70,齿宽为15,50/50毫米.试验结果搞清楚了在自然频率下,齿轮噪声、振动与运行条件之间的关系,并且讨论了运行特性和齿轮齿廓修形的影响.
This paper is an experimental study of the noise and vibration characteristics of high-speed spur gears.Gear noise and vibration are complicated by various factors of the gear system. To clarify its characteristics, we must systematically analyze the interrelationship between various factors In this study, the width of the teeth and the operating conditions of the gears varied and the tests were conducted on a power-absorbing high-speed gear test rig operating at 3000-13000 rpm The test gear used in this study, Modulus 3, pressure angle 20 °, tooth ratio Z_1 / Z_2 35/70, tooth width 15, 50/50 mm Test results Clearly at natural frequency, gear noise, vibration and operating conditions between And discusses the operational characteristics and the effects of gear profile modification.
