Abstract

1. МЕХАНИЗМ КОМПЕНСАЦИИ РАБОТЫ ОБТЮРАТОРА ПРИ КОРРЕКЦИИ КАДРА В КИНОПРОЕКТОРАХ С ЗУБЧАТОРЕМЕННЫМ ПРИВОДОМ, состо щий из ведущего и ведомого зубчатых колес обтюратора , св занных основным зубча Я , ремнем, и рычага, св занного с корпусом мальтийского механизма с помощью поворотного устройства, о тличающийс тем, что, с целью упрощени конструкции, рычаг имеет Т-образную форму и установлен в плоскости основного зубчатого ремн , причем на противоположных кра х полки Т-образного рычага установлены :зубчатые ролики, взаимодействующие с основным зубчатым ремнем, а поворотное устройство состоит из зубчатых колес, св занных между собой дополнительным зубчатым ремнем, одно I из которых жестко установлено на корпусе мальтийского механизма по СЛ оси его вращени , а второе посредством вала жестко св зано с ножкой Т-образного рычага.1. COMPENSATION MECHANISM obturator WORK WITH IMAGE CORRECTION In cinema projector toothed belt drive, consisting of the driving and driven gears obturator associated main ribbed I belt, and a lever associated with the housing Geneva mechanism with the rotary device of the tlichayuschiys that, in order to simplify the design, the lever has a T-shape and is installed in the plane of the main toothed belt, and on the opposite edges of the shelf of the T-shaped lever are installed: toothed rollers that interact with the main toothed belt, and the swivel device consists of gears, connected to each other by an additional toothed belt, one I of which is rigidly mounted on the body of the Maltese mechanism along the SL axis of its rotation, and the second is rigidly connected to the leg of the T-shaped shaft.

Description

2. Механизм по п. 1, о т л ичающийс тем, что, с целью повьшени компактности, он содержит два ограничительных ролика, расположенных в плоскости основного зубчатого ремн на оси, проход щей через2. The mechanism according to claim 1, which is based on the fact that, in order to increase the compactness, it contains two restrictive rollers located in the plane of the main toothed belt on the axis passing through

точку креплени ножки Т-образного рычага.point of attachment of the legs of the T-shaped lever.

3. Механизм поп. 1,отличаю щ и и с тем, что, с целью органичени колебаний основного зубчатого ремн , в нем установлен подпружиненный ролик .3. The mechanism of pop. 1, I differ by the fact that, in order to limit the oscillations of the main toothed belt, a spring-loaded roller is installed in it.

Claims

1. MECHANISM OF COMPENSATION OF THE OPERATION OF THE OBTURANT AT CORRECTION OF THE FRAME IN CINEMA PROJECTORS WITH A GEAR DRIVE, consisting of the drive and driven gear wheels of the obturator connected by a main gear belt and a lever connected with the case of the Maltese device, which in order to simplify the design, the lever has a T-shape and is installed in the plane of the main gear belt, and gear wheels interacting with the bases are installed on opposite edges of the shelf of the T-shaped lever th toothed belt, and the swivel device consists of gears interconnected by an additional toothed belt, one of which is rigidly mounted on the housing of the Maltese mechanism on its axis of rotation, and the second shaft means rigidly connected with the leg of T-shaped lever.

2. The mechanism by π. 1, characterized in that, in order to increase compactness, it contains two restrictive rollers located in the plane of the main gear belt on an axis passing through the attachment point of the legs of the T-shaped lever.

3. The mechanism of pop. 1, it is distinguished by the fact that, in order to limit the vibrations of the main gear belt, a spring-loaded roller is installed in it.
