Description
В существующих лентопрот жных сцепных механизмах дл кинопроекционного аппарата отсутствуют устройства, предотвращающие износ кинолент, что сокращает срок их службы и удорожает эксплуатацию установок.There are no devices that prevent the wear of films, which shortens their service life and increases the cost of operation of installations, in the existing tape-type coupling mechanisms for the film-projection apparatus.
Предлагаемый механизм лишен этого недостатка.The proposed mechanism does not have this disadvantage.
Дл уменьшени износа кинолент в нем применены электромагнитные муфты, приводимые в действие исполнительным электрическим устройством, координированным с электромагнитным тормозом дл киноленты , установленным на подходе ленты к барабану.To reduce the wear of films, electromagnetic clutches are used in it that are actuated by an executive electrical device coordinated with an electromagnetic brake for a film mounted on the approach of the tape to the drum.
Устрой,.тво и принцип действи предлагаемого механизма по сн ютс чертежом.The arrangement, principle and principle of the proposed mechanism are explained in the drawing.
Механ;. ,: имеет барабан дл перемешени киноленты, две электромагнитные муфты и электрическое исполнительное устройство, представл ющее собой сочетание известных электротехнических приборовБарабан / дл перемещени киноленты, свободно вращающийс на валу, снабжен по концам дисками 2 и 3, которые поочередно сцепл ютс с дисками 4 к 5 электромагнитных муфт 7 н 8, что- обеспечивает соединение барабана / то с ведущим валом электромотора 6, то с диском 4, св занным с тормозным устройством.Mekhan. ,: has a drum for mixing the film, two electromagnetic clutches and an electric actuator, which is a combination of well-known electrical devices. The drum / for moving the film, which rotates freely on the shaft, is fitted at the ends with disks 2 and 3, which alternately interlock with disks 4 to 5 Electromagnetic clutches 7 n 8, which ensure the connection of the drum / then with the drive shaft of the electric motor 6, then with the disk 4 connected with the braking device.
Электромагнитные муфты 7 и 5 привод тс в дей|Ствие исполнительным электрическим ус1ройством, состо щим из сочетани известных приборов: генератора 9 с контуром 10, задающего импульсы тока; двух преобразователей П и J2; лимитора/5, устанавливающего длительность токового импульса дл тормозной муфты 7; регул тора М, плавно измен ющего длительность пускового импульса с одновременным изменением длительности тормозного импульса; усилителей токовых импульсов 15 и б.Electromagnetic couplings 7 and 5 are driven by an executive electrical device consisting of a combination of well-known devices: a generator 9 with a circuit 10 that gives current pulses; two transducers P and J2; limiter / 5, setting the duration of the current pulse for the brake clutch 7; a regulator M that smoothly changes the duration of the starting pulse with a simultaneous change in the duration of the braking pulse; current pulse amplifiers 15 and b.
Работа усилител 15 координируетс по каналу/7 с электромагнитным тормозом дл киноленты, установленным на подходе ее к барабану.The operation of the amplifier 15 is coordinated along the channel / 7 with an electromagnetic brake for the film, mounted on its approach to the drum.
