Main shaft system for steel rail online milling and grinding equipment and steel rail milling and grinding vehicle
The embodiment of the invention provides a main shaft system for steel rail online milling and grinding equipment. The main shaft system comprises a box body, the main shaft is arranged in the base; the main shaft can rotate relative to the base; the milling and grinding assembly is connected to one end of the main shaft; the unloading assembly is connected to the other end of the main shaft; and the belt pulley is connected with the unloading assembly and drives the main shaft to rotate through the unloading assembly. The problems that the milling and grinding operation control difficulty is increased and the steel rail milling and grinding operation precision requirement cannot be met due to various forces and vibration impacts borne by a main shaft system of milling and grinding equipment of an existing steel rail milling and grinding vehicle in the operation process are solved. After the main shaft system is subjected to weight reduction design and unloading design, the rigidity of the main shaft is increased, the deflection is reduced, the rotation precision of the main shaft is improved, the whole milling and grinding performance becomes better, the milling and grinding quality of the steel rail is greatly improved, the service life of the steel rail is prolonged, and the railway operation safety is ensured.
本申请实施例提供用于钢轨在线铣磨设备的主轴系统，包括箱体；主轴，设置于所述基座内；所述主轴可相对于所述基座转动；铣磨组件，连接于所述主轴的一端；卸荷组件，连接于所述主轴的另一端；皮带轮，与所述卸荷组件相连，通过所述卸荷组件带动主轴转动。本申请解决了现有钢轨铣磨车铣磨设备主轴系统在作业过程中受到的各种力和振动冲击，进而导致铣磨作业控制难度增加，不能满足钢轨铣磨作业精度要求的问题。主轴系统经过减重设计和卸荷设计后，主轴的刚性增大，挠度减小，主轴的回转精度提高，整个铣削、磨削性能变优，钢轨铣削、磨削质量得到较大提升，延长了钢轨使用寿命，保证了铁路运营安全。
