 (02系列)雙排球式回轉(zhuǎn)支承——內(nèi)齒式

 

結(jié)構(gòu)特點(diǎn)、性能、適用范圍

雙排球式回轉(zhuǎn)支承具有三個(gè)座圈,鋼球和隔離塊可直接排入上下滾道,根據(jù)受力狀況,安排了上下兩排直徑不同的鋼球。這種開式裝配非常方便,上下圓弧滾道的承載角都為90°,能承受很大的軸向力和傾翻力矩。當(dāng)徑向力大于0.1倍的軸向力時(shí)滾道須特殊設(shè)計(jì)。雙排球式回轉(zhuǎn)支承的軸向、徑向尺寸都比較大,結(jié)構(gòu)緊固。特別適用于要求中等以上直徑的塔式起重機(jī),汽車起重機(jī)等裝卸機(jī)械上。
