Abstract
Изобретение позвол ет повысить удобство и оперативность изменени нагрузки на конечных участках траектории движени весла. Нагрузочный узел содержит направл ющую 1 дл лопасти весла 2. В направл ющую 1 вмонтирован электромагнитный блок 3. Полюсные наконечники 7 и 8 магни- топровода блока 3 имеют гребенчатую структуру. Выступы одного наконечника расположены во впадинах другого и разделены диамагнитной прокладкой 10. Между наконечниками 7,8 и закрепленной на направл ющей прокладкой 4 из немагнитного материала имеетс щель дл размещени сменного экрана 13 из диамагнитного материала с профилированным продольным окном 14. На весле 2 закреплена ферромагнитна пластина 5. Обмотка электромагнитного блока 3 подключена к источнику переменного напр жени . Исход из требуемого режима тренировки, подбираетс экран 13 с соответствующим режиму окном 14. Контур действующего на пластину 5 магнитного пол определ етс профилем окна 14, а сила прит жени весла и направл ющей регулируетс напр жением, подаваемым на обмотку электромагнита 3. Сменный экран 13 обеспечивает оперативность изменени нагрузки на концевых участках траектории движени весла. 1 з.п.ф-лы, 4 ил. сл СThe invention makes it possible to increase the convenience and efficiency of changing the load on the end portions of the path of the paddle. The load unit contains a guide 1 for the paddle blade 2. An electromagnetic unit 3 is mounted in the guide 1. The pole tips 7 and 8 of the magnetic conductor of the unit 3 have a comb-like structure. The protrusions of one tip are located in the depressions of the other and are separated by a diamagnetic gasket 10. Between the tips 7.8 and a nonmagnetic material fixed on the guide gasket 4 there is a slot for accommodating a removable screen 13 of diamagnetic material with a shaped longitudinal window 14. At the oar 2 there is a ferromagnetic plate 5. The winding of the electromagnetic unit 3 is connected to the alternating voltage source. Based on the required training mode, the screen 13 is selected with the window 14 corresponding to the mode. The circuit of the magnetic field acting on the plate 5 is determined by the profile of the window 14, and the force of gravity of the oar and the guide is regulated by the voltage applied to the winding of the electromagnet 3. The replaceable screen 13 provides the efficiency of changing the load on the end sections of the path of the paddle. 1 hp ff, 4 ill. sl C
