A design method of a multi-eccentricity eccentric interstage casing lubricating oil pump
The present application belongs to the technical field of structural design and lubricating system design, and relates to a lubricating oil pump structure, in particular to a design method of a lubricating oil pump with a multi-eccentricity eccentric inter-stage shell. The spatial positions of inner and outer rotors are repositioned by offsetting the rotation center of the inner rotor, and the eccentric sleeve is designed along the eccentricity direction based on the value of the large eccentricity. The inter-stage shell structure is designed according to the positions of the inner and outer rotors, i.e. the inter-stage shell is an eccentric inter-stage shell. Compared with the traditional concentric inter-stage shell structure, the radial dimensions of the eccentric sleeve and the inter-stage shell are greatly reduced. The great reduction in size directly reduces the weight of the eccentric sleeve and the inter-stage shell, thereby reducing the overall weight of the lubricating oil pump. In addition, the radial space of the lubricating oil pump is directly reduced, thereby reducing the overall size of the lubricating oil pump.
