卷筒直径不大于两米的卷扬机均属于小型卷扬机,它的卷筒多为整体铸造或将筒壳焊在铸造轮毂上。由于卷筒在工作过程中的应力状态非常复杂,当前进行卷筒强度计算时,通常采用了分别核算单向应力——压缩应力和弯曲应力的方法,并作为较成熟的方法列入了卷扬机设计规范和有关手册中。但依据卷扬机设计规范推荐的公式计算出的卷筒壁厚与实际上采
Winding drum diameter of not more than two meters belong to a small winch, and its reel mostly cast as a whole or the shell welded to the casting hub. Due to the complexity of the stress state during the working process of the reel, current methods of calculating unidirectional stress-compressive stress and bending stress are usually adopted in the calculation of the reel strength, and the winch design is included as a more mature method Specification and related manuals. However, according to the winch design specifications recommended formulas to calculate the drum wall thickness and the actual mining
