Study on Rotor’s Tooth Profiles of Double Enveloping Cycloid Pump
Abstract This paper proposes a new type of internal meshing cycloid rotor pump-Double enveloping cycloid pump. It is characterized by double contact lines between the inner and the outer rotor so that it has outstanding advantages, such as better sealing capacity, higher outlet pressure and volumetric efficiency etc. Based on the brief introduction of the equations of the inner and the outer rotors’ tooth profile, the composition and characteristics of the outer rotor’s tooth profile for the double enveloping cycloid pump are discussed in detail, the calculation method of the normal meshing clearance between the outer rotor and the modified inner rotor is introduced, and the calculation example is given. Result shows that the works in this paper will help to design the new type cycloid rotor pump with high performance.
