Claims (3)

1. Героторный механизм, содержащий внутренний (ротор) и наружный (статор) колеса, зубья которых находятся в непрерывном контакте между собой и имеют разницу в числах зубьев, равную единице, а оси смещены на расстояние эксцентриситета, эллипсоидальный профиль зубчатых колес механизма образован по методу обкатки начальных окружностей, одна из которых (единичного радиуса r), концентрично связанная с исходным вспомогательным контуром, расположена внутри другой неподвижной окружности (радиуса R=kr) и обкатывается по ней без скольжения, отличающийся тем, что в качестве исходного вспомогательного контура используют эллипс, при этом коэффициент пропорциональности k, определяющий радиус направляющей окружности принимают равным половине необходимого числа зубьев z колеса (k=z/2).1. A gerotor mechanism containing internal (rotor) and external (stator) wheels, the teeth of which are in continuous contact with each other and have a difference in tooth numbers equal to unity, and the axes are offset by an eccentric distance, the ellipsoidal profile of the gear wheels of the mechanism is formed by the method the run-in of the initial circles, one of which (of unit radius r), concentrically connected with the initial auxiliary contour, is located inside another fixed circle (of radius R = kr) and is rolled around without slipping, distinguishing This is because an ellipse is used as the initial auxiliary contour, while the proportionality coefficient k, which determines the radius of the guide circle, is taken to be equal to half the required number of teeth z of the wheel (k = z / 2). 2. Героторный механизм по п.1, отличающийся тем, что оптимальная форма его зубьев обеспечивается рациональным сочетанием коэффициента формы эллипса λ, равным отношению длин его полуосей и коэффициента внецентроидности вспомогательного контура представляющим собой отношение длины большой полуоси эллипса к радиусу катящейся окружности.2. The gerotor mechanism according to claim 1, characterized in that the optimal shape of its teeth is provided by a rational combination of the shape coefficient of the ellipse λ, equal to the ratio of the lengths of its axle shafts and the coefficient of eccentricity of the auxiliary contour representing the ratio of the length of the major semiaxis of the ellipse to the radius of the rolling circle. 3. Героторный механизм по пп.1 и 2, отличающийся тем, что внутренний и наружный профили выполняют в виде эллипсоидальных профилей от общего контура эллипса, коэффициент формы эллипса λ и коэффициент внецентроидности со для обеспечения условия сопряжения профилей связаны соотношением3. The gerotor mechanism according to claims 1 and 2, characterized in that the inner and outer profiles are made in the form of ellipsoidal profiles from the general contour of the ellipse, the shape coefficient of the ellipse λ and the eccentricity coefficient с о are connected by the ratio
