Embodiment Construction

[0021] The present invention will be specifically introduced below in conjunction with the accompanying drawings and specific embodiments.

[0022] refer to Figure 2 to Figure 4 , the assembly method of the tracked vehicle load wheel assembly of the present invention adopts a special connection method of threaded mechanical connection plus welding, fastening and airtight, so that the load wheel and the wear-resistant steel ring are firmly combined into one body to form the load wheel assembly. Specifically include the following steps:

[0023] (1), manufacture wear-resistant steel ring 4 blanks by any method, and process to required size, wear-resistant steel ring 4 is preferably made of 38CrSi steel. Then offer the connection concave hole on the wear-resistant steel ring 4, or directly form the connection concave hole when manufacturing the wear-resistant steel ring 4 blank. The angle α of the opening of the connecting recess is preferably 90°.

[0024] (2) Use any method...

Abstract

The invention discloses an assembling method for a bogie wheel disc assembly of a tracked vehicle. The assembling method is characterized by comprising the following steps: concave connecting holes are formed in a wear resistant steel ring; bolt holes which are aligned to the concave connecting holes are formed in a bogie wheel; the wear resistant steel ring is fastened and connected to the bogie wheel through fastening bolts; the concave connecting holes in the wear resistant steel ring are sealed through welding. The bogie wheel is made of aluminum alloy or magnesium alloy materials, and the wear resistant steel ring is made of 38CrSi steel. A special connection mode combining the threaded mechanical connection and the welding and fastening sealing enables the bogie wheel and the wear resistant steel ring to be firmly combined into a whole to form the bogie wheel disc assembly. Compared with the prior art, the method has the advantages that the firmness of the connection of the parts made of two kinds of materials is higher, and the falling-off is prevented; the surface is complete and free of assembling traces, and the quality is high; and the impact resistant performance of the parts manufactured according to the process is far better than that of the parts manufactured according to the conventional process, and a technical support is provided for further improving the motor performance of the tracked vehicle.

Description

technical field [0001] The invention relates to an assembly method of a steel ring, in particular to an assembly method of a wear-resistant steel ring of a load wheel assembly of a crawler vehicle, and belongs to the technical field of assembly design. Background technique [0002] Tracked vehicles, such as crawler cranes, crawler cranes, crawler tractors, crawler bulldozers, etc., will be applied to road wheels on their walking parts. At present, the cold-formed aluminum alloy or magnesium alloy matrix road wheels are produced by cold and hot pressing methods to inlay steel wear-resistant rings. The structure of the obtained road wheel assembly is as follows figure 1 shown. In the road wheel assembly obtained by this method, the inlaid steel wear-resistant ring is easy to detach in an extremely harsh working environment, resulting in a running failure and unstable product quality. [0003] Due to the special requirements of tracked vehicles, the load wheel assembly must h...
