挖掘機(jī)回轉(zhuǎn)裝置由轉(zhuǎn)臺(tái)、回轉(zhuǎn)支承和回轉(zhuǎn)機(jī)構(gòu)等組成，挖掘機(jī)回轉(zhuǎn)支承的外座圈由螺栓與轉(zhuǎn)臺(tái)連接，帶齒的內(nèi)座圈與底架用螺栓連接，內(nèi)、外座圈之間設(shè)有滾動(dòng)體。挖掘機(jī)工作裝置作用在轉(zhuǎn)臺(tái)上的垂直載荷、水平載荷和傾覆力矩通過回轉(zhuǎn)支承的外座圈、滾動(dòng)體和內(nèi)座圈傳給底架?；剞D(zhuǎn)機(jī)構(gòu)的殼體固定在轉(zhuǎn)臺(tái)上，用小齒輪與回轉(zhuǎn)支承內(nèi)座圈上的齒圈相嚙合。小齒輪既可繞自身的軸線自轉(zhuǎn)，又可繞轉(zhuǎn)臺(tái)中心線公轉(zhuǎn)，回轉(zhuǎn)機(jī)構(gòu)工作時(shí)，轉(zhuǎn)臺(tái)就相對(duì)底架進(jìn)行回轉(zhuǎn)。
