Abstract

A cast casing (1) for a large electric motor with a reinforcement component (4), the cast casing for a large electric motor comprising two supporting parts (2) and a connection part (3) connected between the two supporting parts , each of the two supporting parts has a cavity (2-1) and the cavity has a ventilation opening (2-2), the two supporting parts (2) and the connecting part (3) have Mounting through-holes (2‑3) communicating with each other. A reinforcing part (4) with a reinforcing structure is arranged in the ventilation opening (2-2).

Description

technical field [0001] The present invention relates to a cast case for a large electric motor, and in particular to a cast case for a large electric motor having a reinforcement member connected to the cast case for a large electric motor to enhance the strength of the cast case for a large electric motor. Background technique [0002] In the prior art, the casing of a large motor is usually made by casting. In order to obtain a strengthened casing, the casting casing usually has a complex structure and a very thick wall, which will lead to an increase in casting cost. Expensive material and manufacturing costs would result if welded steel shells were utilized. [0003] Based on this reality, there is an urgent need in the art for a large-scale electric motor cast case having a reinforcing part connected to the large-scale electric motor cast case so as to strengthen the strength of the large-scale electric motor cast case. Contents of the invention [0004] In order to ...
