Research on Abrasive Flow Machining for the outer rotor of cycloidal pump
In order to reduce the surface roughness and improve the manufacturing precision of the outer rotor surface of the cycloidal pump,the method that outer rotor tooth surface on the abrasive flow machining (AFM) is adopted.First of all,a power-law model to describe the form of abrasive flow was created,simulation analysis on AFM for the external rotor tooth surface,and the distribution of shear stress that the boundary layer abrasive subjected near the various parts of the outer rotor tooth surface can be draw.Then,choose abrasives with different particle size for processing.Experimental results demonstrate that tooth top,tooth surface and tooth root surface roughness Ra of the outer rotor from the 2.48um 2.192um and 2.107um down to processed 0.054um,0.094um and 0.185um,material removal is 0.4g.AFM method can improve the manufacturing precision of the outer rotor,reduce the radial tooth tip meshing gap,reduce friction and wear of the tooth surface,extend the working life of cycloidal pump.
