Abstract

FIELD: flywheels. SUBSTANCE: contour of flywheel is formed by rotation of geometrical figure symmetrical relative to rotation axis such as ellipse or circle. Flywheel is divided by plane inclined relative to rotation axis by angle less than 90 degrees and more than 0 degrees by two portions, for example having equal volumes. Mass of one portion exceeds that of other portion, for example hollow one, by multiple times. EFFECT: lowered natural beating of flywheel. 1 dwg

Description

Демпферные устройства, предназначенные для уменьшения биений, возникающих при вращении децентрированной относительно оси вращения массы, не достаточно эффективны для способа усиления мощности на валу электродвигателя (патент РФ 2114497), в котором применен именно маховик со смещенным относительно оси вращения центром масс. Damping devices designed to reduce beats that occur during rotation of mass decentered relative to the axis of rotation are not effective enough for a method of amplifying power on an electric motor shaft (RF patent 2114497), in which a flywheel with a center of mass displaced relative to the axis of rotation is used.

Изобретение относится к области машиностроения и электромашиностроения. The invention relates to the field of mechanical engineering and electrical engineering.

Задачей настоящего изобретения является создание маховика со смещенным относительно оси вращения центром масс, который, приведенный во вращение, позволяет существенно снизить или предотвратить собственные вибрации по сравнению с маховиками-эксцентриками, имеющими аналогичное смещение центра масс и аналогичную собственную массу. An object of the present invention is to provide a flywheel with a center of mass displaced relative to the axis of rotation, which, driven into rotation, can significantly reduce or prevent intrinsic vibrations compared to eccentric flywheels having a similar center of mass displacement and a similar unladen mass.

Указанный результат достигается тем, что маховик со смещенным относительно оси вращения центром масс, в соответствии с изобретением, выполнен таким образом, что его форма образована вращением симметричной относительно оси вращения геометрической фигуры, например эллипса, и разделена плоскостью, проходящей под углом меньше 90o и больше 0o к оси вращения, на две части, например, равные по объему, причем масса одной части многократно больше массы другой части, например полой.The specified result is achieved in that the flywheel with the center of mass displaced relative to the axis of rotation, in accordance with the invention, is made in such a way that its shape is formed by the rotation of a geometric figure symmetrical with respect to the axis of rotation, for example an ellipse, and is divided by a plane passing at an angle less than 90 o and more than 0 o to the axis of rotation, in two parts, for example, equal in volume, and the mass of one part is many times greater than the mass of the other part, for example hollow.

Оптимальной формой такого маховика является шар, а разделительная плоскость между его частями проходит под углом 45o к оси вращения.The optimal shape of such a flywheel is a ball, and the dividing plane between its parts passes at an angle of 45 o to the axis of rotation.

Сущность изобретения состоит в перекатывании массы маховика со смещенным относительно оси вращения центром масс, которая расположена под углом к оси вращения, за счет чего происходит снижение собственных вибраций маховика на всех частотах вращения вала, на котором закреплен маховик. The essence of the invention consists in rolling the mass of the flywheel with the center of mass displaced relative to the axis of rotation, which is located at an angle to the axis of rotation, due to which there is a reduction in the natural vibration of the flywheel at all rotational speeds of the shaft on which the flywheel is mounted.

На чертеже (а, б) показаны положения массы маховика, занимающей полусферу, причем одно положение от другого отличается на половину полного оборота. Эти положения показывают перекатывание массы маховика вокруг оси вращения. In the drawing (a, b) the positions of the mass of the flywheel occupying the hemisphere are shown, moreover, one position differs from the other by half a full revolution. These positions show the flywheel mass rolling around the axis of rotation.

Экспериментально установлено, что такое выполнение маховика со смещенным относительно оси вращения центром масс соответствует поставленной задаче. It was experimentally established that such a flywheel with a center of mass displaced relative to the axis of rotation corresponds to the task.
