Description

В насто щее врем  лентопрот жный механизм кннопр01.ктора соедин етс  с ведущим электродвигателем посредством шестеренчатой, ре1Менной или фрикционной передачи. Такие передаточные приспособлени  имеют р д недостатков: они не обеспечивают белнумнэсти передачи, посто нство передаточного отношени  от двигател  к проектору и. кроме того, сложны по устройству.At present, the tape mechanism knop01.ktor mechanism is connected to the driving motor through gear, alternating or friction transmission. Such gears have a number of drawbacks: they do not provide protein transfer, constant gear ratio from the engine to the projector and. besides, are complicated on the device.

Предлагаема  конструкци  устран ет указанные недо ;татки тем, что ротор электродвигател  использован одновременно в качестве обтюратора кинопроектора.The proposed design eliminates these disadvantages by the fact that the rotor of the electric motor is used simultaneously as a shutter of the film projector.

На фиг. 1 схематически изображен обтюратор-ротор электродвигател  в разрезе; на фиг. 2 - вид сбоку.FIG. 1 shows schematically the obturator-rotor of an electric motor in section; in fig. 2 - side view.

Ротор выполнен в виде диска /, диаметр которого позвол ет иметь отверсти , необходимые дл  свободного прохождени  луча света. На диске / укрепл етс  наборный обод 2 ротора, а в корпусе 3 механизма проектора укреплен статор 4. Благодар  значительному радиусу ротора, при сохранении потребной мощности двигател , конструкци  его получаетс  плоской.The rotor is made in the form of a disk /, the diameter of which allows for openings necessary for the free passage of a beam of light. On the disk / the composing rim of the rotor 2 is fastened, and the stator 4 is strengthened in the housing 3 of the projector mechanism. Due to the considerable radius of the rotor, while maintaining the required engine power, its design is flat.

Таким образом, предлагаемое устройство устран ет специальные передаточные приспособлени  от электродвигател  к кинопроектору и приводит в движение лентопрот жный механизм кинопроектора.Thus, the proposed device eliminates special transmissions from the electric motor to the film projector and drives the film-throwing mechanism of the film projector.

Предмет изобретени Subject invention

Обтюратор-ротор электродвигател  дл  кинопроектора, отличающийс  тем, что, с целью устранени  специальных передаточных приспособлений от электродвигател  к лентопрот жному механизму кинопроектора , а также обеспечени  посто нства передаточного числа, он выполнен в виде диска с отверсти ми, который одновременно служит ротором электродвигател , привод щим в движение лентоп ют жный механизм кинопроектора.An obturator-rotor of an electric motor for a film projector, characterized in that, in order to eliminate special transmission devices from the electric motor to the tape-drawing mechanism of the film projector, as well as to ensure the stability of the gear ratio, it is made in the form of a disk with holes, which simultaneously serves as a rotor of an electric motor, drive the movement of the film-projection mechanism.
