Валы 7 и 8 сид т JB подшипниках 72 и .i/5 рычагов 14 и /5 подвижных ,рамок 16 и 17. Подвижные рамкн 16 и 17 ход т в направл ющих 18, получа  свое движение от привода в виде кулачков 19 и 20, установленных диамет эально-противоположно друг другу на оси 2/ шагового двигател  22. Рычаг 10 через вал 9 и рычаг // через йал (не показан) св заны ,с рычагами 23 и 24 подвижных, рамок 25 и 25, в которых расположены .кулачки 27 и 25,-жестко закрепленные на валу 29 электродвигател  30.rigidly connected to the lever-differential mechanismol, which are levers 5 and 6, rigidly connected to shafts 7 and 8, and lever 10 mounted on shaft 9 and lever // mounted on shaft (not shown). Shafts 7 and 8 sit JB bearings 72 and .i / 5 of the arms 14 and / 5 of the moving, frames 16 and 17. Movable frames 16 and 17 move in the guides 18, getting their movement from the drive in the form of cams 19 and 20, the diameters established are aially opposite to each other on the axis 2 / of the stepper motor 22. The lever 10 through the shaft 9 and the lever // through the yal (not shown) are connected, with the arms 23 and 24 moving, the frames 25 and 25 in which the cams are located 27 and 25, rigidly mounted on the shaft 29 of the electric motor 30.

Механизм поочередного ввода шторок в Световой поток состоит из -перемещающейс  в направл ющей 5/ т ги 32, на которой закреплены .штифты , .которые вход т в пазы а, б, в, г рычагов 5, 5, 10 к 11..The mechanism of alternate entry of the shutters into the luminous flux consists of a moving 5 / ti rail 32, on which pins are fastened, which enter the grooves a, b, c, and d of the levers 5, 5, 10 to 11.

На т ге 32 жестко закреплен штифт 37, св занный с пружинами 38 и 39, которые посредством штифтов 40 и 41 св заны с кареткой 42, ход которой осуществл етс  от привода аппарата (не показан). Положение штифта 57 и соответственно т ги 32 фиксируетс  поочередно рцчагами 43, и 44 ,сТ1ружинамй 45 и 46. Рычаги 43 и 44 сид т на ОСЛУ. 47 и 48. ;A pin 37 is rigidly fixed on the t 32 and associated with the springs 38 and 39, which by means of the pins 40 and 41 are connected with the carriage 42, the stroke of which is driven by the drive of an apparatus (not shown). The position of the pin 57 and, accordingly, of the gig 32 is fixed alternately with the 43 and 44 grips, the CT 45 and 46 grips. The levers 43 and 44 are mounted on the OSL. 47 and 48.;

Пружины 38VL 39 имеют удлиненные петли д VI е. Т га 32 имеет ограничители . . . .Устройство работает следующим образом .The springs 38VL 39 have elongated loops d VI e. T ha 32 has stops. . . The device works as follows.

Шторки / и 2 наход тс  (-фиг. I) в рабочем положении. Штopkи 3 к 4 выведены из рабочего положени . Двигатель 30. вращаетс . Кулачками 27 и 28, сид щими на валу 29 двигател  30, перемещаютс  рамки 25- ,и 26, определ ющие рассто ние между шторками 5 и 4. Когда нужное рассто ние между шторками 3 к 4 будет nuJiy4eHO,двиг ,атель 30 останавливаемс . За опреде .ленноеврем  до смены плана начинает двигатьс  каретка 42, при этом штифт 41 освобождает рычаг 44, а штифт 40 заводит пружнну 55, В конце своего движени  Щхнфт 40 удар ет рычаг 43 и освобождает штифт 57. Под действием заведенной пружины 55 т га 5i2 перемещаетс  влево до ©граничи гел  50 и фиксируетс  -рычагом 44. Под действием пружины SS т га 52 через штифты 55, .54, 55 и56, вход щие впазы ,. . . - ; .. X 1.,The shutters / and 2 are in the working position (-fig. I). Strokes 3 to 4 are out of working position. Engine 30. rotates. The cams 27 and 28, which sit on the shaft 29 of the engine 30, move the frames 25- and 26, which determine the distance between the shutters 5 and 4. When the desired distance between the shutters 3 and 4 is null, the engine 30 is stopped. After some time before the plan change, the carriage 42 begins to move, while the pin 41 releases the lever 44, and the pin 40 starts the spring 55, At the end of its movement, Shchnft 40 hits the lever 43 and releases the pin 57. Under the action of the spring 55 tons ha 5i2 moves to the left up to the edge of the gel 50 and is fixed by the lever 44. Under the action of the spring SS t ha 52 through the pins 55, .54, 55 and 56, the incoming grooves,. . . -; .. X 1.,

Далее повтор етс  то же самое со, шторкам,и 1 и 2, т. е. они выставл кЗтс  на определенное рассто ние, -друг от- друга симметричйо оптической оси и когда .нужноввод тс  в рабочее положение. Соответственно Щторкй 5 и 4 одновременно будут выведены; В результате повышаетс  быстродействие; устройства, так .как оноопредел етс  быстродействием механизма по очередного ввода шторок в световой поток, которое обеспечиваетс  за счет того, что перемещение т ги мало (не превышает 3-4. лгж); повыш:аетс  точность регулировани  светового потока, котора  определ етс  работой привода, масса деталей и узлов которого не вли ет отрицательно на фа,бЬту предлагаемого устройства; .повышаетс  .стабильность работы устройства, так как износ элементов деталей, работающих с большой скоро-стью, не оказывает существенного вли ни  на точность работы во времени.a, b, c, and d of levers 5, 6, 10, and 11, moves, shields, curtain 5, and 4- s working position, and curtains / and 2 are removed from the working position. Then the same is repeated with the curtains and the curtains 1 and 2, i.e., they exhibit a spike over a certain distance, a friend from the other with a symmetrical optical axis and when it is necessary to move to the working position. Accordingly, Shtorky 5 and 4 will be simultaneously withdrawn; As a result, the speed increases; the device, as it is determined by the speed of the mechanism by the next input of the blinds into the luminous flux, which is ensured by the fact that the movement of the rod is small (does not exceed 3-4 lg); increase: the accuracy of the adjustment of the luminous flux, which is determined by the operation of the drive, the mass of parts and assemblies of which does not adversely affect the phase of the proposed device; The stability of operation of the device increases, since the wear of elements of parts operating at high speeds does not significantly affect the accuracy of work in time.
