辊道是轧钢厂数量最多的设备之一。目前,辊道轴颈与锥齿轮过盈配合的装拆方法有三种:压入法、温差法和静压法。前两者用得最普遍,静压法近年来才获得越来越广泛的应用。压入法仅适用于过盈量不大的地方。当传递较大扭矩时,常常用键作辅助联接,结构复杂,而且削弱了轴的强度。温差法适用于过盈量比较大的地方,能传递较大载荷,也可以不使用辅助联接,但装配后一
Roller mill is the largest number of rolling mill equipment. At present, roller shaft and bevel gear interference fit with the assembly and disassembly methods are three: press-in method, temperature difference method and static pressure method. The first two are most commonly used, and the hydrostatic method has gained more and more widespread use in recent years. Press-fit method is only suitable for small amount of interference. When the transmission of large torque, often with a key for the auxiliary connection, the structure is complex, and weakened the shaft strength. The temperature difference method is suitable for the place where the interference is relatively large, can transmit larger loads, and can not use the auxiliary connection, but after the assembly
