Abstract

The invention discloses a novel structure of a rotor and a manufacturing technology of the novel structure of the rotor. The manufacturing technology comprises the following steps that the step (1), parts are manufactured, specifically, a rotor blade is manufactured through a mold, a rotor front cover plate and a rotor rear cover plate are manufactured in a machining mode, and a rotor shaft is manufactured in a machining mode; the step (2), the parts are assembled, specifically, the rotor blade sleeves the rotor shaft in an empty mode, and then the rotor front cover plate and the rotor rear cover plate are connected to the rotor shaft and the rotor blade in an expanded mode or welded on the rotor shaft and the rotor blade, so that the whole rotor is formed; and the step (3), finish machining is conducted, specifically, the shaft neck, the excircle and the end face of the whole rotor obtained in the step (2) are subjected to precision machining, the profile of the whole rotor is subjected to precision milling or planing machining, and finally the novel precise structure of the rotor is obtained. The novel structure of the rotor and the manufacturing technology of the novel structureof the rotor well overcome the defects that in the prior art, the rotor weight is large, materials are not uniform, the manufacturing technology is relatively complex, the quality is poor, and the cost is high.

Description

technical field

[0001] The invention relates to the technical field of engineering machinery, in particular to a novel structure of a rotor and a manufacturing process thereof. Background technique

[0002] The rotor is the main part of the rotor pump used to pump and discharge various liquids. The quality of the rotor affects the overall performance of the entire pump body. It is increasingly urgent to improve the quality of the rotor and reduce the cost.

[0003] At present, the existing traditional rotors mainly adopt sand casting, which has problems such as difficult casting, complex casting process, long production cycle, poor quality of rotor blanks, and unstable mechanical properties of the rotor. There are many defects in the traditional rotor manufacturing method, which easily leads to poor material uniformity and thermal stability of the rotor, and reduces the service life of the rotor.

[0004] Therefore, there is an urgent need for a new rotor structure with pr...
