A SIMPLIFIED CALCULATION METHOD FOR FIXED VALUE OF P/M SWING ROTOR IN OIL PUMP

The fixed value of swing type of oil pump rotor is an important target for controlling and inspecting rotors quality. By using the principle of the formation of rotor thread contour and the relevant knowledge,the present article deduced a principle for calculating the fixed value of rotor and gave a more simplified method. The method has been widely used in the practice of producing rotor products in the plant, and has achieved good results.
