在捷尔任斯基冶金厂的烧结厂中,采用由电动机经三角皮带传动而带动振动器的自定中心振动筛来实现烧结矿的筛分(图1)。由于烧结矿是断续地加到振动筛上去的,所以除了由振动器引起的振动作用外,在振动筛的弹性系统中还产生了由于所加上去的料而引起的附加振动。这导致了三角皮带传动装置的中心矩的周期性变化,变化量达9毫 In the sintering plant at the Dzerzhinsky Metallurgical Plant, sifting of the sinter is carried out using a self-centering shaker driven by a motor driven by a V-belt drive and vibrator (Fig. 1). Since the sinter is intermittently applied to the vibrating screen, in addition to the vibrating action caused by the vibrator, additional vibrations due to the added material are also generated in the vibrating screen elastic system. This resulted in a periodic change in the center moment of the V-belt drive with a variation of 9 milliliters
