Rotation driving device for railway ballast excavation
The invention relates to a rotary driving device for railway ballast excavation, and belongs to the technical field of rail transit. The bottom of a supporting piece of the device is formed by connecting a middle large ring and small rings on the two sides to form a bottom plate, the middle of the bottom plate is connected with a flange ring on the top, the middle of the lower surface is fixedly connected with an inner ring, and the inner ring and an outer gear ring form a rotating pair. The outer gear ring is fixedly connected with the upper end of the box body; the two sides of the lower surface of the supporting piece bottom plate are fixedly connected with half-shell-shaped shaft end covers correspondingly and used for installing a gear shaft, and the gear shaft is provided with a lower outer tooth part meshed with the outer gear ring. The top of the supporting piece is fixedly connected with the hanging lug, and small rings on the two sides of the supporting piece support and install the brake and the motor with the brake respectively. The braking ends of the two brakes are connected with the corresponding gear shafts in a clutch mode respectively, and the output shaft of the motor is in transmission connection with the spline parts of the gear shafts through a spline pair. By the adoption of the device, driving asynchronization can be avoided, large holding torque is provided, railway ballast excavation is more convenient and reliable, and meanwhile the safety of constructors is guaranteed.
本发明涉及一种道砟挖掘回转驱动装置，属于轨道交通技术领域。该装置支撑件的底部由中部大环与两侧小环连体底板构成，底板中部与顶部的法兰圈连体、下表面中部与内圈固连，内圈与外齿圈构成转动副；外齿圈与箱体的上端固连；支撑件底板的下表面两侧分别固连半壳体状轴端盖，用于安装齿轮轴，齿轮轴具有与外齿圈啮合的在下外齿部；支撑件顶部与挂耳固连，且其两侧小环分别支撑安装制动器和带制动器的马达；两制动器的制动端分别与相应的齿轮轴可离合衔接，马达的输出轴通过花键副与齿轮轴的花键部传动连接。采用本发明可避免驱动不同步，又提供较大的保持力矩，使道砟挖掘更加便捷可靠,同时保证施工人员安全。
