机械工业部1980年10月修订的《单、双点压力机产品质量分等规定》中规定:合格品噪声≤90分贝,优等品噪声≤87分贝,一等品噪声≤88分贝。实际上、机械压力机的工作噪声一般为90～110分贝。这不仅严重危害职工的身心健康,影响工作效率,而且还严重地阻碍了压机的出口创汇。因此,必须采取有效措施控制噪声。机械压力机工作噪声控制的最根本办法是治理噪声源。而机械压力机工作噪声源主要来自模具一工件系统与压机本身传动系 Ministry of Machinery Industry revised in October 1980 “single and double point press product quality regulations” provides: Qualified product noise ≤ 90 dB, superior product noise ≤ 87 dB, first-class product noise ≤ 88 dB. In fact, the working noise of a mechanical press is generally 90 to 110 dB. This not only seriously endanger the physical and mental health of workers, affecting work efficiency, but also seriously hindered the press export earnings. Therefore, effective measures must be taken to control the noise. Mechanical presses the most fundamental way of working noise control is to deal with noise sources. The mechanical press noise source mainly from the mold a workpiece system and the press itself drive train
