Description

(54) ЭЛЕКТРОМЕХАНИЧЕСКИЙ ПРИВОД ИСКУССТВЕННОЙ КИСТИ(54) ELECTROMECHANICAL DRIVE OF ARTIFICIAL BRUSH

Изобретение относитс  к области медицинской техники, а именно к механизмам протезов верхних конечностей.The invention relates to the field of medical technology, in particular to the mechanisms of upper limb prostheses.

Известен электромеханический привод искусственной кисти, содержащий электродвигатель, редуктор , несамотормоз щуюс  винтовую пару с гайкой и винтом и узел фиксащ1и в виде механизма свободного хода 1 .The electromechanical drive of an artificial brush is known; it contains an electric motor, a reducer, a non-self-braking screw pair with a nut and a screw, and a fixing unit in the form of a free wheeling mechanism 1.

Целью изобретени   вл етс  упрощение конструкции и уменьщение габаритов протеза.The aim of the invention is to simplify the design and reduce the size of the prosthesis.

Это достигаетс  тем, что узел фиксации выполнен в виде подвижного стакана, установленного на шарикоподпшпнике, контактирующего своим тор)цом с корпусом редуктора и св занного с винтом при помощи механизма свободного хода, расположенного внутри стакана. Цричем механизм свободного хода вьшолнен в виде эксцентрика, неподвижно расположенного на винте, и роликов, установленных с возможностью заклинивани  между эксцентриком и стаканом.This is achieved by the fact that the fixing unit is made in the form of a movable cup mounted on a ball bearing in contact with its gearbox and connected with a screw by means of a free wheeling mechanism located inside the cup. The free-wheeling mechanism is executed in the form of an eccentric fixedly mounted on the screw and rollers installed with the possibility of jamming between the eccentric and the glass.

На фиг. 1 изображен электромеханический привод искусственной кисти в разрезе; на фиг. 2 - сечение по А-А на фиг. 1.FIG. 1 shows the electromechanical drive of an artificial brush in the section; in fig. 2 is a section along A-A in FIG. one.

Устройство содержит электродвигатель 1, редуктор 2, несамотормоз щую винтовую пару с гайкой 3 и винтом 4, узел фиксации, вьшолненный в виде подвижного стакана 5, установленного на щарикоподщипнике 6, контактирующего своим торцом и корпусом редуктора 2 и св занного с винтом 4 при помощи механизма свободного хода, расположенного внутри стакана 5 и вьшолненного в виде эксцентрика 7, неподвижно расположенного на винте 4, и роликов 8, установленных с возможностью заклинивани  между эксцентриком 7 и стаканом 5.The device contains an electric motor 1, a gearbox 2, a non-self-locking screw pair with a nut 3 and a screw 4, a fixing unit, made in the form of a movable cup 5 mounted on a ball support 6, contacting with its end face and gear case 2 and connected with screw 4 by means of a mechanism free running, located inside the glass 5 and made in the form of an eccentric 7, fixedly located on the screw 4, and rollers 8, installed with the possibility of jamming between the eccentric 7 and the glass 5.

Устройство работает следующим образом.The device works as follows.

При вращении винта 4 в направлении, соответствующем сближению пальцев кисти и передачи мощности от двигател  1 к винту, последний в стакане 5 благодар  эксцентрику 7 свободно прокрзд1иваетс  и опорным шарикоподшипником  вл етс  подщипник 6. При передаче мощности от винта к двигателю и вращении винта в обратном направлении винт вращаетс  вместе со стаканом 5 и опорным щарикоподщипником  вл етс  подщипник скольжени , образованньш торцом стакана. При раскрытии пальцев с помощью двигател  опорным подщипником  вл етс  щариковый подщипник 9.When the screw 4 is rotated in the direction corresponding to the approaching of the fingers and transferring power from the engine 1 to the screw, the latter in glass 5, thanks to the eccentric 7, is free to move and the supporting ball bearing is bearing 6. the screw rotates with the cup 5 and the supporting ball holder is a slide bearing, formed by the end of the cup. When opening the fingers with the help of an engine, the ball bearing is a ball bearing 9.
