The invention provides a rotating wheel and engineering equipment. The rotating wheel comprises a main shaft, a wheel body and a support; the wheel body is arranged on the main shaft in a sleeving mode, and the support is connected with the main shaft; and the main shaft penetrates through the wheel body and the support, the support is provided with an extending-in part extending into the wheel body, and an elastic sealing ring is arranged between the extending-in part and the wheel body. According to the rotating wheel and the engineering equipment, the elastic sealing ring is arranged between the support and the wheel body, axial extrusion is formed between the wheel body and the support, radial expansion is formed on the elastic sealing ring through rotation of the wheel body, therefore the elastic sealing ring can block an internal channel where a medium flows to the wheel body, and the sealing effect is achieved.
本发明提供了一种旋转轮和工程设备。旋转轮包括:主轴;轮本体,轮本体套设于主轴上;支架,支架与主轴连接;其中,主轴贯穿轮本体与支架,支架具有伸入轮本体内的伸入部分,伸入部分与轮本体之间设有弹性密封圈。本发明通过在支架与轮本体之间设置弹性密封圈,使得轮本体与支架形成轴向的挤压,且轮本体的转动对弹性密封圈形成径向扩张,从而使得弹性密封圈能够堵塞介质流向轮本体的内部通道,从而起到密封的作用。
