| 带式输送机缓冲托辊的正确选择 Correct Selection of Buffer Roller for Belt Conveyor 托辊在带式输送机中的应用十分重要，它支撑着输送带，并且承受着物料的重量。由此可见托辊的作用十分重要。所以托辊的结构性能就显得更加的重要。 The application of idler in belt conveyor is very important. It supports the conveyor belt and bears the weight of material. It can be seen that the role of idlers is very important. So the structure and performance of the idler is more important. 缓冲托辊专用高分子材料，重量轻，比重是钢材的七分之一，用这种材料制成的托辊，重量是普通托辊配件的二分之一左右，旋转惯性小，托辊与皮带之间的磨擦小，有效的减少之间的摩擦。 Buffer roller special polymer material, light weight, specific gravity is one seventh of the steel. The weight of the roller made of this material is about one-half of the ordinary roller fittings, small rotary inertia, small friction between roller and belt, effectively reducing friction between them. 缩小托辊间距可减少模拟摩擦系数，但阻力总值会增大，除在卸载点为保护胶带外在一般承载段不要加大托辊密度。此外，缓冲托辊橡胶圈耐磨损，使用寿命长。托辊辊体专用高分子材料，其继续性能类似于青铜，具有很好的耐磨性，而且具有良好的自润滑性能，不伤皮带。 Reducing the spacing of idlers can reduce the simulated friction coefficient, but the total resistance will increase. The density of idlers should not be increased in the general load-bearing section except for the protective tape at the unloading point. In addition, the rubber ring of cushioning roller is wear-resistant and has a long service life. The special polymer material for roller body has good wear resistance, good self-lubrication and no damage to the belt, and its continuing performance is similar to that of bronze. |
