Abstract
A numerical value calculation model of a variable capacity-type gear pump is constructed on a computer (step 1); one or two or more temporary levers are provided on an outer ring and it is assumed that contact points of a compression spring are located at the temporary levers (step 2); a movement rule of the outer ring is defined (steps 3, 4, and 5); the outer ring is moved based on the movement rule to obtain a set of positional coordinate values of the contact points (steps 6, 7, 8, and 9); based on a statistical amount obtained by statistical processing on the set of coordinate values (step 10), appropriateness of the position of the temporary lever is determined (steps 11, 12, and 13).
