However, it has been found that such conventional wheel devices have the following problems:
1. the gear part and the wheel are integrally formed, and the material is 40Cr or 45 steel, so that the gear part is made of medium-hardness materials and has poor wear resistance;
2. when the wheel device rotates, sliding friction exists between the working surface of the wheel and the transition side surface of the gear part and the lower flange of the track beam, so that larger friction noise is generated when the wheel rotates;
3. when the transition side face is worn to a certain degree, the gear part is worn, the gear part made of medium-hard materials is worn quickly and replaced, and the gear part and the wheel are of an integral undetachable structure, so that the replacement of the gear part means the replacement of the wheel, however, the cantilever wheel device needs to detach the crane from the track beam before the wheel is replaced, and then put the crane on the ground, so that the maintenance and the replacement of the wheel take time and effort.
In the traveling wheel 8 of the present utility model, the tooth 81 and the traveling wheel 8 are integrally formed, and the above-described technical shortcomings exist objectively, and the tooth 81 in the cantilever wheel device only serves as a single function of the input gear since the output gear 61 is mounted on the polygonal rod 6 and engaged with the tooth 81 to drive the traveling wheel 8.
Disclosure of Invention

In order to improve the mounting flexibility of the power input part, the wheel shaft is provided with a shaft hole communicated with the internal spline, and the aperture of the internal spline is smaller than that of the shaft hole. Therefore, the power input part can drive the wheels in a mode of extending into the shaft hole and then connecting with the spline hole, and can also drive the wheels in a mode of directly connecting with the spline hole.
The two bearings are arranged along the axial direction of the wheel shaft and are separated by the retainer ring through the holes arranged on the inner hole wall of the wheel, and a oiling passage for grease to pass through is arranged along the axial direction of the wheel shaft and is communicated with the spacing space of the two bearings, so that good lubrication is provided for the bearings.

The gear and the wheel are arranged in a split mode, so that the gear can be made of high-hardness materials to improve the wear resistance of the gear, and similarly, the spline board with the split mode can be made of high-hardness materials.
The utility model has the following advantages and beneficial effects:
1. after the gear and the wheel shaft are separated and detachably arranged, the special strength and hardness requirements can be adopted according to the gear process requirements, the materials are not required to be adopted, and the materials are not required to be adopted, so that not only is the conditions for improving the wear resistance of the gear created, but also the gear worn for a long time is convenient and quick to replace and saves time and labor, thereby overcoming the defect that the gear part and the wheel are integrated and cannot be detached in the prior art, and simultaneously the added separated and detachable flower keyboard has the characteristics of wear resistance, convenient and quick self replacement when worn or damaged, and time and labor saving;
2. because the outer diameter of the gear is smaller than that of the wheel, when the wheel of the device runs on the track beam, the gear always does not generate friction with the lower flange of the track beam, so that the device only has rolling friction between the wheel and the track beam, and the noise is low;
3. the device has two sets of input modes of different forms, namely a gear and a spline, when a driving transmission device (such as a gear motor) is configured, the driving transmission device can select the driving transmission gear, at the moment, the spline board can be used as an output end, and the driving transmission device can also select the connecting spline board, and the gears can be used as the output ends, so that the device has the dual functions of input and output.
