1 问题的提出麻阳铜矿选矿厂有6台TD62系列胶带运输机,其尾轮拉紧装置均采用螺旋拉紧装置,它是利用拧动螺杆来移动尾轮,从而拉紧皮带的。尾轮轴通过整体式滑动轴承支持在滑座上,轴承用油杯润滑,滑座可在支架上滑动,螺杆穿过嵌入滑座上部凹槽中的方螺母,当旋转螺杆时,滑座带动尾轮轴一起移动,而使皮带拉紧或放松。近几年,随着我矿井下开采条件日益恶化,进入选矿厂的矿石含泥明显增多,在这种潮湿、多泥
1 PROBLEM PROPOSED Mayang Copper Mine concentrator has 6 sets of TD62 series of belt conveyors. The tail tightening device adopts the spiral tightening device. It tightens the belt by tightening the screw to move the tail wheel. The tail shaft is supported on the sliding seat by an integral sliding bearing, the bearing is lubricated by a oil cup, the sliding seat can slide on the supporting frame, the threaded rod passes through a square nut embedded in the upper groove of the sliding seat, and when the screw is rotated, The axles move together, straining or relaxing the belt. In recent years, with the mine deteriorating mining conditions, ore into the ore dressing plant significantly increased, in this wet, mud more
