双排异径球式回转支承(02系列)
双排球式回转支承有三个座圈,钢球和隔离块可直接排入上下滚道,根据受力状况,安排了上下两排直径不同的钢球。这种形式装配非常方便,上下圆弧滚道路的承载角都为90度。能承受很大的轴向力和倾翻力矩。当径向力大于0.1倍的轴向力时,滚道路须特殊设计,结构坚固。特别适用于要求中等以上直径的塔式起重机,汽车起重机等装卸机械上。
the double-row ball style slewing ring has three seat-rings, steel balls and spacers may be poured directly into upper&nether; orbits.two rows of upper&nether; steel balls of different diameters can be assembled according to undertaking power situation.the kind of open-pattern-assembly is very convenience. the load-angles of upper&nether; circular orbit are 90 °, so it is able to undertake very large axial force and tipping moment.when radial force is 0.1 multiple of axial force,the orbit need to be redesigned.the axial&radial; size of this kind of slewing ring all are rather big and the structure is firm,so it is especially suitable for some loading&unloading; machines of over-medium diameter,such as,tower crane,truck crane,and so on.
