Description

Technical Field

[0001] The utility model relates to the technical field of composite cast iron wheels, in particular to a composite cast iron wheel. Background Art

[0002] Currently, cast iron wheels used in many heavy machinery applications, such as cranes, conveyor belts and road rollers, are mainly manufactured through iron metal injection molding. This cast iron wheel uses an integrated injection molding method to ensure that the cast iron wheel has a good integrity. At the same time, such a cast iron wheel has a high degree of stability and reliability, which is very important in different and harsh working environments.

[0003] However, the disadvantage is that this integrated design limits the partial disassembly and independent repair or replacement of parts. During use, if the cast iron wheel parts are partially worn or damaged, simple local repair or replacement cannot be carried out, and the entire wheel must be replaced. This not only increases the complexity of maintenance work, but also leads to a significant increase in maintenance costs, especially for this type of heavy equipment, the repair and replacement costs are already relatively high.

[0004] Based on this, we propose a composite cast iron wheel to solve the above-mentioned problems. Utility Model Content
