我矿选矿车间所用的筛子为自定中心振动筛。传动系统在筛子负荷略重时,筛子偏心轴就下沉,导致轴端的皮带轮也随之下降,这样振动筛开动起来三角皮带因松而打滑,造成筛子不能振动,直接影响生产。为了解决上述矛盾,我们在三角皮带的松边增加张紧槽轮,见图。此槽轮的轮槽同两传动皮带轮的轮槽一样,用定位销定好位置,一般情况下开车正常。若矿石来的过多或过猛时,即使筛子被压死, The sieve used in my mineral processing plant is a self-center shaker. Transmission system in the sieve load is slightly heavy, the screen eccentric shaft sinks, leading to the shaft end of the pulley also will fall, so that the vibrating screen to start up the V-belt due to loose and slippery, causing the sieve can not be vibration, a direct impact on production. In order to solve the above contradictions, we increase the tension pulley in the loose side of the V-belt, see figure. The wheel groove of this sheave is the same as the wheel groove of the two transmission pulleys, and the position pin is used to set a good position, under normal circumstances, the car is normal. If the ore comes too much or too much, even if the sieve is crushed,
