The broad gauge diesel locomotive solid wheel that the utility model provides, the external profile diameter scope of wheel rim contact track has satisfied the gauge requirement of broad gauge locomotive bottom, the thickness range of wheel rim has been guaranteed the complete wear consumption range of sizes of wheel, the width of wheel rim has guaranteed that wheel contacts with the normal of track, makes in orbit safe operation of locomotive.
Description of drawings
The front view of the solid wheel that Fig. 1 provides for the utility model;
Fig. 2 be among Fig. 1 along A-A to cutaway view.
The specific embodiment
As shown in Figure 1 and Figure 2, present embodiment provides a kind of broad gauge diesel locomotive solid wheel, this wheel is made of wheel hub 1, wheel rim 2 and the disc 3 that is connected wheel hub 1 and wheel rim 2, the outer rim 21 diameter D of wheel rim 2 contact tracks are between 1080mm ~ 1083mm, the thickness d of wheel rim 2 is more than or equal to 74.5mm, and the width L of wheel rim 2 is between 140mm ~ 143mm.
The broad gauge diesel locomotive solid wheel that the utility model provides, material meets the regulation of T steel among the standard GOST10791-2011, tread 22 is that wheel rim radial edges profile meets " locomotive tread contour profile " requirement among the GOST11018-2000, and the wheel diameter complete wear consumes limit diameter D
1Be 1000mm, outer rim 21 diameter ranges of wheel rim 2 contact tracks can satisfy the gauge requirement of broad gauge locomotive bottom, the thickness range of wheel rim 2 has guaranteed that wheel can reach complete wear consumption range of sizes and guarantee that wheel reaches the minimum thickness value of requirement of strength in complete wear is decreased range of sizes, the width L of wheel rim 2 has guaranteed that wheel contacts with the normal of track, makes in orbit safe operation of locomotive.As the preferred implementation of present embodiment, the thickness d of wheel rim had both been guaranteed the requirement of strength in the wheel complete wear consumption range of sizes between 74.5mm ~ 77mm, can not cause increasing because wheel is overweight extra load again.
