The supporting seat is manufactured by welding seamless steel pipes and steel plates in a combined manner, the supporting plate is supported on the upper portion and the lower portion of the wheel body, the stress portion of the roller is arranged in the middle of the wheel body and needs to be assembled twice, namely, the steel pipes and the lower supporting seat are assembled and welded firstly, then the supporting plate is assembled with the wheel body, and then the supporting plate is installed. In order to make the bearing convenient, a manufacturer also adopts a cast steel type bearing seat, but the cast steel bearing seat has rough appearance, often has casting defects such as sand inclusion or sand holes, has large workload of polishing and welding repair, has lower strength than the bearing seat welded by a seamless steel pipe, and has unstable quality.

Disclosure of Invention

The purpose of the invention is as follows: aiming at the defects and shortcomings of the prior art, the problem that the concave-convex wheel manufactured by the traditional method is low in strength is solved, the seamless steel tube is used for manufacturing, the reinforcing rib and the tube wall body are welded and fixed, the manufacturing cost is low, the efficiency is high, the appearance is attractive, and the strength requirement can be met.

The technical scheme is as follows: in order to achieve the above purpose, the present invention provides a concave-convex wheel formed by deforming a steel pipe, which is applied to the preparation of rolling wheels for ships, and comprises a pipe wall, a base and a fixed bottom ring, wherein the base is in the shape of an open horn with two ends of concentric circles with different diameters, the pipe wall is in the shape of a dumbbell with two high ends and a low middle part, the concave-convex wheel is formed by stretching and extruding a seamless steel pipe, the shape of the outer surface of the base changes into a circular arc curve shape, one end of the pipe wall is provided with an end cover, the other end of the pipe wall is provided with the fixed bottom ring, the outer surface of the end cover is an arc surface, the arc surface of the end cover is connected with the arc of the end of the pipe wall, the edge of the outer ring of the fixed bottom ring is fixed in the end socket at one end of the pipe wall far away from the end cover, the shaft sleeve is tightly combined with the small opening of the base through interference fit.

In the inner cavity of the pipe wall, a supporting sleeve is arranged on the outer side of the shaft sleeve and is in a seamless tubular shape.

And reinforcing ribs are arranged between the support sleeve and the inner wall of the pipe wall, and the number of the reinforcing ribs is at least 2.

And an anti-corrosion layer is arranged on the outer surface of the pipe wall.

And the outer surface of the end cover is provided with a wear-resistant layer.

The reinforcing ribs are welded and fixed with the supporting sleeve and the pipe wall.

Has the advantages that: compared with the prior art, the utility model, its beneficial effect is:

compared with the prior art, the utility model discloses marine unsmooth wheel body is through stretch forming by seamless steel pipe for overall structure, and the bearing passes through bearing plate and gyro wheel body welded fastening, and inside axle sleeve passes through interference fit and the base combines closely. The utility model discloses the cost of manufacture is low, production efficiency is high, and is both pleasing to the eye, can satisfy the intensity requirement of marine gyro wheel again, installation convenient to use.
