Problems solved by technology

[0002] The defect of the existing technology is that: the gear teeth need subsequent high-frequency quenching treatment to improve the hardness and performance of the teeth, while the rotor needs surface hardening treatment (such as nitriding treatment, steam treatment, etc.), two different treatment methods lead to It is not easy to realize the combined cycloidal rotor

Abstract

The invention relates to the field of machines, in particular to a combined cycloid rotor and a preparation method thereof. The combined cycloid rotor comprises an outer rotor body with an outer circle being provided with a tooth disc, and an inner cycloid rotor body matched in the molded line. The outer rotor body comprises the cylindrical outer circle. The tooth disc is arranged at the end face,close to the cylindrical outer circle, of the outer rotor body and formed by N sets of tooth crests and tooth troughs which are arranged alternately and distributed circumferentially and evenly. A groove is formed in the intersection of the tooth disc and the outer circle. An inner cavity of the outer rotor body is a cavity designed according to the pump flow requirement. The cavity is formed bycircumferentially and evenly distributing N tooth-shaped arcs and 2N transition arcs r. The inner rotor body comprises a cylindrical inner hole. The two ends of the cylindrical inner hole are providedwith chamfers facilitating assembling. An outline curve of the inner rotor body is a cycloidal curve conjugated with an inner cavity curve of the outer rotor body. The number of teeth of the cycloidal curve is one fewer than that of the outer rotor body.

Description

technical field [0001] The invention relates to the field of machinery, in particular to a combined cycloidal rotor and a preparation method thereof. Background technique [0002] The defect of the existing technology is that: the gear teeth need subsequent high-frequency quenching treatment to improve the hardness and performance of the teeth, while the rotor needs surface hardening treatment (such as nitriding treatment, steam treatment, etc.), two different treatment methods lead to It is not easy to realize the combined cycloidal rotor. Contents of the invention [0003] The purpose of the invention: to provide a combined cycloidal rotor with better effect and its preparation method [0004] For the specific purpose, see the multiple substantive technical effects in the specific implementation part. [0005] In order to achieve the above object, the present invention takes the following technical solutions: [0006] A combined cycloidal rotor, characterized in that ...
