[0003] In order to adapt to the new situation of the leap-forward development of the railway, the traditional equipment and facilities in the train can no longer meet the needs of the development of the situation. The equipment and facilities in the train are humanized to improve the comfort, practicality, safety and interior The beauty of the environment has become a topic for rail vehicle equipment and component manufacturers

[0004] As we all know, the rotation function of the rotating seat on domestic bullet trains is realized by the rotation of the turntable or the bearing. Whether it is the turntable or the bearing, after a period of operation, the mechanism will wear out and its stability will decrease. With the prolongation of the running time of the passenger car, the wear and tear of the parts of the rotating part is increasing, which leads to the continuous decline of the reliability and stability of the rotating seat, and the cost of the existing rotating seat is also very high
