Пример осуществления изобретения An example embodiment of the invention
Тороидально-винтовой редуктор-преобразователь включает винт 1, преобразователь 2. Винт 1 выполнен в виде тороида (далее тороидальный винт) правильной геометрической формы с непрерывной резьбой 3 на поверхности по всей длине окружности тора. В примере конкретного выполнения тороидальный винт 1 содержит трехзаходную резьбу. Шаг резьбы, форма и направление (правая, левая) могут быть выполнены различным образом. Тороидальный винт 1 может быть выполнен различного диаметра и сечения. Тороидальный винт 1 выполнен из металла. Также для его изготовления могут быть использованы различные материалы, например: полимеры (фторопласт, капролон, полиуретан и т.д.), комбинированные материалы (металл-полимер, металл-магнитные компоненты) и т.д. Преобразователь 2 выполнен в виде цилиндрического тела с внутренней
полостью 4, отверстиями 5, взаимосвязанными с шариками 6. Тороидальный винт 1 размещен во внутренней полости 4 преобразователя 2 посредством зацепления шариков 6 с соответствующими витками резьбы 3 тороидального винта 1. В точке взаимодействия преобразователя 2 и тороидального винта 1 их оси 7 и 8 совпадают. Преобразователь 2 в свою очередь взаимосвязан с планетарной парой отбора мощности, выполненной в виде зубчатых колес 9, 10 . Также редуктор содержит опорно-приводные ролики 11, маховик привода 12. Toroidal helical gearbox-converter includes screw 1, converter 2. Screw 1 is made in the form of a toroid (hereinafter toroidal screw) of regular geometric shape with a continuous thread 3 on the surface along the entire circumference of the torus. In a specific embodiment, the toroidal screw 1 comprises a three-way thread. The thread pitch, shape and direction (right, left) can be performed in various ways. Toroidal screw 1 can be made of various diameters and cross sections. Toroidal screw 1 is made of metal. Also, various materials can be used for its manufacture, for example: polymers (fluoroplast, caprolon, polyurethane, etc.), combined materials (metal-polymer, metal-magnetic components), etc. The Converter 2 is made in the form of a cylindrical body with an internal cavity 4, holes 5, interconnected with balls 6. A toroidal screw 1 is placed in the inner cavity 4 of the transducer 2 by meshing the balls 6 with the corresponding threads of the toroidal screw 3 screw 1. At the point of interaction of the transducer 2 and the toroidal screw 1, their axes 7 and 8 coincide. Converter 2, in turn, is interconnected with a planetary power take-off pair made in the form of gears 9, 10. The gearbox also contains support-drive rollers 11, the flywheel of the drive 12.
При работе редуктора вращение с маховика привода 12 передается на опорно-приводные ролики 11, приводящие в движение тороидальный винт 1. Вращаясь вокруг оси 13, тороидальный винт 1 совершает поступательное движение через преобразователь 2, шарики 6 которого, двигаясь по резьбе 3 винта 1 как по направляющим сообщают преобразователю 2, взаимосвязанному с планетарной парой 9, 10 вращательное движение. When the gearbox is operating, the rotation from the flywheel of the drive 12 is transmitted to the supporting-drive rollers 11, which drive the toroidal screw 1. Rotating around the axis 13, the toroidal screw 1 translates through the converter 2, the balls 6 of which, moving along the thread 3 of the screw 1 as the guides inform the transducer 2, interconnected with the planetary pair 9, 10 rotational motion.
В работе заявляемого устройства используют «централизованный» метод взаимодействия - угловая скорость тороидального винта 1 увеличивает угловую скорость преобразователя 2 за счет прохождения в осевой части 7 преобразователя 2 шаго-витка 14 и достигается эффект передачи вращательно-поступательного движения во вращательное в замкнутом динамическом цикле, за один шаго-виток 14 - один оборот зубчатого колеса 9 любой длины окружности. Чем короче шаго-виток 14, тем длиннее шаговый цикл тороидального винта 1 на расчетной длине окружности. Эффективность закручивания преобразователя 2 достигается за счет многозаходности шаго-витка 14, при этом длина окружности тороидального винта 1 решающим образом не влияет на эффективность работы редуктора, а увеличение числа оборотов зависит от количества шаго- витков14 на одном шаговом цикле (шаговый цикл- количество шаго-витков 14 на длине окружности тороидального винта 1, совершающих один оборот).
Заявителем разработан опытный образец заявляемого изобретения, который имеет следующие параметры: In the operation of the inventive device, a “centralized” interaction method is used — the angular velocity of the toroidal screw 1 increases the angular velocity of the transducer 2 due to the passage of step-turn 14 in the axial part 7 of the transducer 2 and the effect of transferring rotational-translational motion to rotational in a closed dynamic cycle is achieved, for one step-turn 14 - one revolution of the gear wheel 9 of any circumference. The shorter the step-turn 14, the longer the step-by-step cycle of the toroidal screw 1 at the calculated circumference. The twisting efficiency of the converter 2 is achieved due to the multi-start of the step-turn 14, while the circumference of the toroidal screw 1 does not decisively affect the efficiency of the gearbox, and the increase in the number of revolutions depends on the number of step-turns 14 in one step cycle (step cycle - number of steps turns 14 on the circumference of the toroidal screw 1, making one revolution). The applicant has developed a prototype of the claimed invention, which has the following parameters:

Общий вес 5 кг Total weight 5 kg
За один оборот маховика 12 тороидальный винт совершает 15 шаго- витков, что соответствует 15 оборотам в секунду или 900 оборотам в минуту на преобразователе 2. For one revolution of the flywheel 12, the toroidal screw makes 15 steps, which corresponds to 15 revolutions per second or 900 revolutions per minute on the converter 2.
