挖掘机回转装置由转台、回转支承和回转机构等组成，挖掘机回转支承的外座圈由螺栓与转台连接，带齿的内座圈与底架用螺栓连接，内、外座圈之间设有滚动体。挖掘机工作装置作用在转台上的垂直载荷、水平载荷和倾覆力矩通过回转支承的外座圈、滚动体和内座圈传给底架。回转机构的壳体固定在转台上，用小齿轮与回转支承内座圈上的齿圈相啮合。小齿轮既可绕自身的轴线自转，又可绕转台中心线公转，回转机构工作时，转台就相对底架进行回转。

转台的主要承载部分是由钢板焊成的抗扭和抗弯刚度很大的箱形结构，主架、动臂及其液压缸就支承在主梁的凸耳上。液压挖掘机工作时转台上部自重和载荷的合力位置是经常变化的，并偏向载荷方向。为平衡载荷力矩，转台上的各个装置需要合理布置，并在尾部设置配重，以改善转台下部结构的受力，减轻挖掘机回转支承的磨损，保证整机的稳定性。

挖掘机在工作中能够左右转动，离不开回转装置，回转支承就回转机构的重要一部分。由于挖掘机的回转支承一般都在大载荷工况工作，再加上挖掘机工作环境都比较恶劣，回转支承很容易出现故障。挖掘机回转支承厂家提醒您，为保障挖掘机回转支承的优良性能，进行定期保养
