1.引言今天在愈来愈广泛的工业领域要求降低噪声,随着机械化的增加而增加的噪声构成,以及与此相连系的环境污染,带来了大量以法律形式固定下来的条文和数目更多的个别规定。另外,竞争的形势要求工业品的生产者更严格的减小噪声。在运输机械中除了发动机外,首先要求传动系最后直到轮胎的元件减少噪声,特别是齿轮箱和轴。尽管10kW以上传递功率的行星传动原则上比同样功率的圆柱齿轮传动噪声小,如《德国工程师协会》(VDI)2159条所指出的,同样对它也要求大幅度的降低噪声。下面要讨论的是对运输机械,功率范围在50
1. INTRODUCTION Today’s demanded reduction of noise in an increasingly widespread industrial area, the increased noise composition associated with increased mechanization, and the associated environmental pollution have led to a large number of provisions and numbers more legally fixed More individual provisions. In addition, the competitive situation requires producers of industrial products to reduce noise more strictly. In transportation machinery, in addition to the engine, it is first required that the driveline last until the components of the tire reduce noise, in particular gearboxes and shafts. Although planetary transmissions above 10 kW transmit power in principle, they are less noisy than spur gear drives of the same power, as also pointed out by the German Society of Engineers (VDI) 2159, which also requires significant noise reduction. The following discussion is on the transport machinery, the power range of 50
