Abstract

1. Гибкий вал для передачи крутящего момента, содержащий концевые элементы, соединенные закрепленной на них винтовой цилиндрической пружиной, и ось, установленную внутри пружины и сочлененную концами с концевыми элементами, отличающийся тем, что ось выполнена гибкой и состоит из первого набора полых цилиндров, последовательно сочлененных друг с другом сферическими или коническими торцовыми поверхностями, одна из которых выполнена выпуклой, а другая - вогнутой, при этом вал снабжен гибкой оболочкой, охватывающей пружину, состоящей из второго набора полых цилиндров, последовательно сочлененных друг с другом сферическими или коническими торцовыми поверхностями, одна из которых выполнена выпуклой, а другая - вогнутой, при этом гибкий вал установлен в подшипниковых опорах, расположенных периодически по всей его длине, в первом наборе цилиндров периодически установлены подшипники, через которые натянут трос между концевыми элементами.2. Гибкий вал по п.1, отличающийся тем, что по меньшей мере один набор полых цилиндров подпружинен для их поджатия друг к другу.3. Гибкий вал по пп.1 и 2, отличающийся тем, что по меньшей мере на одном полом цилиндре гибкой оболочки смонтирована шестерня.4. Гибкий вал по п.3, отличающийся тем, что полый цилиндр, на котором смонтирована шестерня, сцеплен с пружиной посредством пальца.1. A flexible shaft for transmitting torque, containing end elements connected by a coil spring attached to them, and an axis mounted inside the spring and articulated by ends with end elements, characterized in that the axis is flexible and consists of a first set of hollow cylinders, in series spherical or conical end surfaces connected to each other, one of which is convex and the other concave, while the shaft is provided with a flexible shell covering a spring consisting of a second of a set of hollow cylinders sequentially connected to each other by spherical or conical end surfaces, one of which is convex and the other is concave, while the flexible shaft is installed in bearing bearings located periodically along its entire length, bearings are periodically installed in the first set of cylinders through which the cable is pulled between the end elements. 2. The flexible shaft according to claim 1, characterized in that at least one set of hollow cylinders is spring-loaded to compress them against each other. The flexible shaft according to claims 1 and 2, characterized in that the gear is mounted on at least one hollow cylinder of the flexible shell. The flexible shaft according to claim 3, characterized in that the hollow cylinder on which the gear is mounted is engaged with the spring by means of a finger.
