Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clear, the present invention is further described in detail below. It should be understood, however, that the description herein of specific embodiments is only intended to illustrate the invention and not to limit the scope of the invention.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs, and the terms used herein in the specification of the present invention are for the purpose of describing particular embodiments only and are not intended to limit the present invention.
As shown in fig. 1, a road roller press wheel comprises a wear-resistant steel rim 1, a left sealing plate 2, an internal reinforcing rib 3, an inner ring 4, a right sealing plate 5, an external reinforcing rib 6, a left support plate 8 and a right support plate 7;
the left sealing plate 2 and the right sealing plate 5 are welded on the wear-resistant steel rim 1, and inner holes in the left sealing plate and the right sealing plate are coaxial with the wear-resistant steel rim 1; the inner ring 4 is welded between the left sealing plate 2 and the right sealing plate 5 and is coaxial with the inner holes of the left sealing plate and the right sealing plate; the left support plate 8 and the right support plate 7 are welded on the inner ring 4, and the inner holes of the left support plate and the right support plate are coaxial with the inner holes of the left sealing plate and the right sealing plate; the inner reinforcing ribs 3 are welded on the inner side of the left sealing plate 2, the inner side of the right sealing plate 5 and the outer side of the inner ring 4; and the external reinforcing ribs 6 are respectively welded on the outer side of the left sealing plate 2, the inner side of the wear-resistant steel rim 1 and the outer side of the right sealing plate 5.
As shown in fig. 2, an asymmetric weld is used at the edge-rolling weld of the wear-resistant steel rim 1, and further, the size of the outer groove 9 is small, and the size of the inner groove 10 is large, so that the bead grinding amount of the outer groove 10 can be reduced, and the influence of the strength and hardness of the outer bead on the entire rim can be reduced.
