Description
Применением тормозного ремн , номещенного в выточке холостого шкива фрикционной муфты и соединенного своими концами со шнинде.1 ми рычагов двух половин кулачковой муфты, сид щей свободно на втулке первой муфты, имеетс в виду получить фрикционную передачу дл швейных машин, при чем один из рычагов кулачковой муфты св зан т гой со станиной машины , а другой, при иомош,и стержн , соединен с ее педалью.By using a brake belt placed in the recess of the idler pulley of the friction clutch and connected to the ends with shninde.1 levers of the two halves of the cam clutch, which sits loosely on the hub of the first clutch, it is intended to get a friction gear for sewing machines The clutches are connected to the machine bed, and the other, with an iomosh, and rod, is connected to its pedal.
На схематическом чертеже фиг. 1 изображает общий вид предлагаемого фрикциона , фиг. 2 - вид кулачковой муфты п фиг. 3-вид рычагов этой муфты.In the schematic drawing of FIG. 1 shows a general view of the proposed clutch; FIG. 2 shows a cam clutch in FIG. 3-view of the levers of this coupling.
Фрикционна передача дл швейных машин состоит из стальной втулки 1 с фрикционной муфтой в виде холостого шкива О и рабочего шкива 4, расположенного в выточке 12 шкива 9 тормозного ремн 13, и кулачковой муфты 16 с рычагами 23, 24 и закрепленными на последних шпиндел ми 17, 18, при чем рычаг 24 св зываетс т гой со станиной машины, а рычаг 23 посредством стержн соедин етс с ее педалью .The friction gear for sewing machines consists of a steel sleeve 1 with a friction clutch in the form of a single pulley O and a working pulley 4 located in the groove 12 of the pulley 9 of the brake belt 13, and a cam clutch 16 with levers 23, 24 and fixed on the last spindles 17, 18, whereby the lever 24 is connected with the machine bed, and the lever 23 is connected to its pedal by means of a rod.
При нажатии на педаль машины рычаг 23 опускаетс книзу, вследствие чего кулачки ыуфты 16 начинают расходитьс и муфта, встретив сопротивление закрепительной шайбы 6, сдвинетс в сторону холостого шкива 9, прижима его к рабочему шкиву 4. После прекращени нажати на педаль, последн от имеющейс под ней пружины поднимаетс вверх вместе с рычагами 23, отчего кулачки муфты 16 сдвинутс и шкив 9, отт гиваемый тормозным ремнем 13, отойдет от шкива 4.When the machine pedal is pressed, the lever 23 descends downwards, as a result of which the coupling of the coupling 16 begins to diverge and the clutch, having met the resistance of the fixing washer 6, moves towards the idler pulley 9, pressing it against the working pulley 4. After stopping pressing the pedal, the last The springs go up together with the levers 23, which causes the clutch cams 16 to move and the pulley 9 pulled by the brake belt 13 will move away from the pulley 4.
Предмет патента.The subject of the patent.
Фрикционна передача дл швейных машин, характеризующа с применением тормозного ремн 13 (фиг. 1 и 2), расположенного в желобке шкива 9 фрикционной муфты и соединенного концами со шпиндел ми 17 и 18 (фиг. 2) рычагов 24 и 23 (фиг. 2 и 3) обеих половин кулачковой муфты 16 (фиг. 1 и 2), сид щей свободно на втулке фрикционной муфты, из каковых рычагов рычаг 24 (фиг. 2 и 3) св зан т гой со станиной машины, а рычаг 23 соединен стержнем с педалью.A friction gear for sewing machines, characterized using a brake belt 13 (Fig. 1 and 2) located in the groove of the pulley 9 of the friction clutch and connected to the ends with spindles 17 and 18 (Fig. 2) of the levers 24 and 23 (Fig. 2 and 3) both halves of the cam clutch 16 (Fig. 1 and 2), the friction clutch seated freely on the sleeve, of which the levers 24 (Fig. 2 and 3) are connected to the machine bed, and the lever 23 is connected by a rod to the pedal .
