FIELD: engines and pumps.SUBSTANCE: invention relates to methods of inertia tests of chain gears. Essence of the invention consists in the fact that to an input shaft of a chain gear there connected is an output shaft of an electric motor and fixed is a body with a reference moment of inertia, and moment of inertia of the chain gear is determined as ratio of a sum of a product of difference of angular acceleration of a system of rotating masses "electric motor, chain gear, body with reference moment of inertia" and angular acceleration of a system of rotating masses "electric motor, chain gear" for moment of inertia of the electric engine and a product of angular acceleration of the system of rotating masses "electric engine, chain gear, body with reference moment of inertia" for moment of inertia of the body with reference moment of inertia to difference of angular acceleration of the system of rotating masses "electric engine, chain gear" and angular acceleration of the system of rotating masses "electric engine, chain gear, body with reference moment of inertia".EFFECT: invention allows determining moment of inertia of a chain gear.1 dwg |
