Problems solved by technology

[0002] At present, the wheel sets of cranes in our country are all angular bearing box wheels. This kind of wheel design is outdated, and it is still produced according to the drawings in the 1960s. Gnaw the rail, and it is labor-intensive and time-consuming to manufacture, and the assembly process is complicated

Embodiment Construction

[0008] Embodiments are described in detail in conjunction with the above accompanying drawings, as Figure 1-Figure 4 As shown, the end beam 11 is made of a cold-formed rectangular tube, which not only reduces the weld seam, but also has high strength and aesthetic appearance, and the driving wheel axle 1 is stepped (such as image 3 ), the step 12 at one end is fixed with a self-aligning roller bearing 7, and the other end is fixed with a spacer sleeve 4. The end of the driving wheel shaft connected to the reducer is made into a flat key or splines, the outer shape of the bearing chamber 3 is square, and the spherical roller bearing is assembled in the bearing chamber and cannot be moved by its inner convex edge. Further, from figure 1 The cross-section of the marked bearing chamber 3 shows that the bearing chamber is an inverted Z shape. The purpose of this setting is that when the spherical roller bearing needs to be replaced, only the bearing chamber needs to be removed, a...

Abstract

The invention discloses a bearing box on a European type crane. The bearing box comprises a driving wheel axle, an end beam and a driving wheel, the driving wheel is in a step shape, a self-aligning roller bearing is fixed to a step at one end, a self-aligning roller bearing is fixed to the other end through a spacer sleeve, the end, connected with a reduction box, of the driving wheel axle and ismade into a flat key or a spline, the self-aligning roller bearings are assembled into a bearing chamber and are clamped through internal protruding edges to be free of movement, the protruding edgesinside the bearing chamber abut against outer rings of the self-aligning roller bearing, and fixed bolt holes connected with an end beam are arranged at the four corners of the bearing chamber; innerrings of the self-aligning roller bearing are matched with the driving wheel axle, the driving wheel axle is connected with a driving wheel through the flat key, an opening is formed in the position,in the center of the wheel axle, of the end beam, and the width of the opening is larger than the diameter of the matched position of the driving wheel axle and the driving wheel. The bearing box canbe directly used in cooperation with high-quality reduction boxes such as SEW and ABM, the maintaining cost is reduced, the manufacturing cost of a plant is saved, and a large amount of plant input is saved for clients.

Description

technical field [0001] The invention relates to a European-style crane wheel, which is especially suitable for matching with the European-style crane. Background technique [0002] At present, the wheel sets of cranes in our country are all angular bearing box wheels. This kind of wheel design is outdated, and it is still produced according to the drawings in the 1960s. Rail gnawing, and time-consuming manufacturing, complex assembly process. Contents of the invention [0003] The task of the present invention is to propose a bearing box on a European-style crane with small volume, large bearing capacity and convenient assembly and maintenance. [0004] The task of the present invention is accomplished in this way, it comprises driving wheel axle, end beam and driving wheel, it is characterized in that: driving wheel axle is ladder-shaped, is fixed with self-aligning roller bearing on the step of one end, and its other end uses spacer sleeve The self-aligning roller bear...
