随着我国国民经济的发展,电机噪声已被视为“公害”;同时,我国出口电机数量日益增大,且均对噪声要求严格。基于上述原因,降低电机噪声、特别是降低出口电机噪声的问题已成为当前广泛重视且急待解决的问题。几年来,为了满足电机对低噪声轴承的要求,一方面抓紧制定了有关的专业标准;另一方面又不断改进了轴承制造工艺。到目前为止,许多轴承厂已正式生产电机专用轴承(带补充代号Z或Z_1,Z组适用于一
With the development of our country’s national economy, motor noise has been regarded as “public hazard”. Meanwhile, the number of export motors in our country has been increasing day by day, and both require strict noise. For the above reasons, the problem of reducing the motor noise, especially the noise of the outlet motor, has become a currently widespread issue and an urgent problem to be solved. In recent years, in order to meet the motor requirements for low noise bearings, on the one hand, quickly developed the relevant professional standards; the other hand, the continuous improvement of the bearing manufacturing process. So far, many bearing factory has been formally produced motor bearings (with additional code Z or Z_1, Z group for a
