一、传动装置噪声产生的根源 在一台密封的传动装置里,常常会产生很大的噪声,这主要是由于齿轮传动轴和轴承以及安装结构之间复杂的相互运动或动力传递所造成。当一对齿轮在啮合过程中,由于齿轮的几何参数、制造误差和装配误差等因素,会引起周期性的加速分离或加速啮合,则将产生齿与齿之间的撞击,导致传动齿上的动负荷,其最大的瞬时值发生在运行中的最大误差。见图一。动负荷的产生相似于
First, the source of transmission noise Generated in a sealed transmission, often have a lot of noise, mainly due to the gear shaft and the bearing and the complex structure caused by mutual movement or power transmission caused. When a pair of gears are meshed, due to the geometric parameters of gears, manufacturing errors and assembly errors and other factors, will cause periodic accelerated separation or accelerated engagement, it will produce a tooth-to-tooth impact between, resulting in the drive teeth Dynamic load, the maximum instantaneous value of the maximum error in operation. See figure one. Dynamic load generation is similar to
