[0002] Railway is an important part of my country's transportation, and railway track is one of the basic infrastructures of railway transportation. In particular, turnout track, due to its large number, complex structure, short service life, speed limit, low driving safety, and high maintenance investment, has become the three weak links of railway along with curves and joints.

[0003] When the rails on the railway line are rolled to a certain extent, their contour shape changes, the contact geometry between the wheelset and the rails deteriorates, and the smoothness of operation and the service life of the rails are damaged. Therefore, since the speed increase of my country's railways, the railway department has attached great importance to the profile grinding of the line rails. In the related technology, the profile grinding of railways is usually mainly carried out by grinding machines, but because there are tracks with a certain deflection angle in the rails, when the grinding device grinds this area, it is usually necessary to stop grinding and adjust the output position of the motor according to the direction of the track, thereby affecting the grinding efficiency of the track.

The driving assembly 5 includes an offset reduction motor 51, and a driving gear 52 is fixedly connected to the output shaft of the offset reduction motor 51, and the driving gear 52 is coaxially arranged with the output shaft of the reduction motor 51. A transmission housing 10 is provided outside the driving gear 52, and the transmission housing 10 is fixedly connected to the outer shell of the offset reduction motor 51.

[0027] A hexagonal hole gear 53 is meshed with one side of the driving gear 52. A hexagonal sleeve 6 is passed through and fixedly connected to the center of the hexagonal hole gear 53, and the hexagonal sleeve 6 is fixedly connected to the transmission housing 10. A hexagonal shaft 9 is fixedly connected inside the hexagonal sleeve 6.

The connector 54 in this embodiment is configured as a cross universal shaft coupling, and the two ends of the cross universal shaft coupling are respectively connected to the worm 3 and the hexagonal shaft 9. At the same time, in order to ensure the synchronization of the master and slave ends, the cross universal shaft coupling adopts a double-connection type in this application, and the double connection method can be connected by welding or flanges and bolts. The cross-axis universal coupling utilizes the characteristics of its mechanism. Its two shafts are not on the same axis.
