托辊是带式输送机的基本部件,可保证其可靠运行和维修费用低廉的必要条件是设计托辊时正确考虑各种影响托辊使用寿命的因素以及使托辊结构更趋于合理。因近年来国内带式输送机吊挂托辊组应用很少,而吊挂托辊组与槽型托辊组相比,在承载能力、使输送机运行平稳、防输送带跑偏及降 Roller is the basic part of belt conveyor, to ensure reliable operation and maintenance costs are low, the necessary conditions for the design of roller correctly consider the various factors that affect the life of the roller and roller structure more reasonable. In recent years, there are few applications of the domestic conveyor belt suspension roller group, while the suspension roller group and the groove type roller group compared to the carrying capacity, the conveyor running smoothly, anti-conveyor belt deviation and drop
