双轴直线振动筛是具有较高生产率和筛分效率的筛分机械之一(见图1)。目前在国内外都得到广泛的应用。振动器是它的发振机构;是振动筛的主要部件,其激振力是由两个质量相等的偏心轴(偏心块)作反向同步旋转而产生的,通常采用的结构是用一对大小相等齿数相同的齿轮将两个偏心轮联接,由电机经三角皮带传动,使两偏心轴作反向同步旋转(见图2)。 Biaxial linear vibrating screens are one of the screening machines with high productivity and screening efficiency (see Figure 1). Currently at home and abroad have been widely used. Vibrator is its vibration mechanism; Vibrating screen is the main component, the excitation force is two equal mass eccentric shaft (eccentric block) for reverse synchronous rotation generated, the commonly used structure is a pair of Equal number of teeth of the same number of gears will be linked to two eccentric, by the motor through the V-belt drive, the two eccentric shafts for reverse synchronous rotation (see Figure 2).
