现代长距离的带式输送机需用数百个托辊组,其价值约占输送机的25%。因此应力求减少输送机托辊组的数量增大其间距。以往研究这个问题时,通常是在分析任何一个因素——例如胶带的垂度、胶带在托辊上趋入角等等影响的基础上进行的。可是,托辊组的间距由很多综合因素决定,其中主要的是保持胶带槽形断面的形状和托辊所受的荷载。此外,应当考 Modern long-distance belt conveyors require hundreds of idler sets, accounting for about 25% of the conveyor’s value. Therefore, we should strive to reduce the number of conveyor roller sets to increase its spacing. The previous study of this problem was usually based on the analysis of any one factor - such as the dip of the tape, the impact of the tape on the idler roller, etc. However, the spacing of the idlers is determined by a number of factors, the main one being the shape of the tape slot and the load on the idler. In addition, we should test
