sliding noise

Mechanism of noise during the running of sintered metal self-oiling bearings and the instrument and method for the determination of sliding noise have been described . The present paper gave emphasis on the main factors of influences on the sliding noise of self-oiling bearings during running .

介绍了烧结金属含油轴承运转时产生噪音的机理和测定滑动噪音的装置及方法，重点介绍了影响含油轴承运转时滑动噪音的主要因素。

Identification of the wear of metal sliding friction by noise envelope spectrum

金属滑动摩擦磨损的噪声包络谱识别

Double wall construction of the sliding door : noise reduction , energy saving and heat protection ;

前门双层壁式结构：隔热、隔噪音，操作舒适节省能源；

WPC treatment could produce many fine pits on the metal surface , which can contain lubricant so that wearing and friction of the sliding part and noise can be reduced .

WPC加工使其金属表面产生无数细小凹痕，能起到积存润滑油的作用，因而减小了滑动部分的磨损和摩擦，并可降低噪声。
