Problems solved by technology

(3) Cracks are prone to occur at the joint between the rim and the rim, mainly due to low mold preheating temperature and unreasonable structure
If the arc at C is too small, sharp corners will be formed, which will increase the tendency to form cracks and easily form crack defects

Abstract

The invention discloses a metallurgy mine vehicle wheel which comprises a tread and a hub. The tread and the hub are integrally formed and perpendicularly connected; the connecting position of the tread and the hub extends outwards in the horizontal direction of the hub to form a rim; the hub and the rim are located on the same horizontal plane; and a shaft hole is formed in the center of the hub.Through tread force analysis, the bearing requirement can be met, and the metallurgy mine vehicle wheel is higher in load-bearing capacity; and the wheel is simple in designed structure, low in costand beautiful in appearance.

Description

technical field [0001] The invention relates to the technical field of making mine car parts, in particular to a metallurgical mine wheel. Background technique [0002] Mine car wheels are one of the conventional products of industrial and mining machinery, and most of them are produced by metal mold casting. In many years of production practice, corresponding preventive measures have been taken for the defects that are more likely to occur, which effectively reduces the metal mold casting of mine wheels. The probability of defect generation makes the yield of mining wheels reach more than 95%. Defects such as pores, shrinkage cavities, shrinkage porosity, and cracks are prone to occur in the metal mold casting of mine wheels; the main reasons for this are (1) pores are easily generated at the shaft hole. In the original process, the shaft hole was formed by a metal mold (sand core No. 2 was not used in the past, and it was originally a part of the upper mold of the metal m...
