Description

Дл  осуществлеви  плавного регулировани  производительнсстн масл ного насоса в пределах от нул  до максимума, вне зависимости от числа оборотов, предлагаетс  шестеренчатый масл ный насос, устройство которого по сн етс  чертежом . Все детали насоса монтируютс  в корпусе 8. Сид щие на общем 5алу 3 ведущие шестерни / и 2 жестко св заны друг с другом, причем шестерн  J зацепл етс  с левой частью ведомой шестерни 4, наход щейс  в рабочей камере корпуса 8,   шестерн  2 с ее правой частью, расположенной в холостой камере корпуса 8. Камеры В и С разделены вращающейс  вместе с шестернейшайбой-диафрагмой 7. От продольного перемещени  щайба 7 здерживаетс  кольцевым выступом, вход щим в паз корпуса 8. Внутренн   зубчата  часть шайбы 7 притерта по зубчатой поверхности . шестерни 4. При продольном движении вала 5 щестерн  4 перемещаетс  из одной камеры корпуса в другую. Слева от шестерни 4 на вал 5 насажена запорна  колодка 6. Вогнута  поверхность колодки 6 притерта по радиусу , равному радиусу ведущей шестерни /.For smooth adjustment of the performance of the oil pump ranging from zero to maximum, regardless of the number of revolutions, a gear oil pump is proposed, the device of which is illustrated in the drawing. All parts of the pump are mounted in the housing 8. The 3 pinion gears / and 2 that are on the common 5 are rigidly connected to each other, with the pinion J gearing with the left side of the driven gear 4 located in the working chamber of the housing 8, the pinion 2 with its the right side, located in the idle chamber of the housing 8. The chambers B and C are separated rotating with the gear washer-diaphragm 7. From the longitudinal movement, the orifice 7 is held by an annular protrusion entering the groove of the orifice 8. The internal gear part of the washer 7 is lapped on the toothed surface. gears 4. With the longitudinal movement of the shaft 5, the gear 4 moves from one chamber of the housing to another. On the left of gear 4, a locking pad 6 is mounted on shaft 5. The surface of pad 6 is ground inward along a radius equal to that of the pinion gear /.

В крайнем лево.м положении скольз н1,нх деталей (валика 5, шестерни 4 и запорной колодки 6) шестерн  / зацепл етс  с шестернейпо всей ее длине и насос работает с максимальной производительностью . При продвижении валика 5 вправо, щестерн  4 вступает в зацепление с шестерней 2, а запорна  колодка 6 закрывает своей вогнутой поверхностью часть шестерни , котора  таким образом выключаетс  из работы. Производительность насоса уменьшаетс  по мере уменьшени  рабочей длины шестерни /. В крайнем правом ноложении nieстерн  4 полностью находитс  в камере С и зацепл етс  только с шестерней 2. Запорна  колодка 6 в этом положении целиком закрывает зубь  шестерни 2 и насос работает вхолостую.In the leftmost position of the slide n1, nx parts (roller 5, gear 4 and locking pad 6), the gear / meshes with the gear over its entire length and the pump operates at its maximum capacity. When the roller 5 is advanced to the right, the brush gear 4 engages with gear 2, and the locking pad 6 closes with a concave surface a part of the gear that is thus turned off from work. The pump performance decreases as the working gear length decreases. In the extreme right position, nister 4 is completely in chamber C and engages only with gear 2. Locking pad 6 in this position completely closes gear tooth 2 and the pump runs idle.

Предмет и з о б р е т е н и   Шестеренчатый масл ный насос с регулируемой производительностью, о т л и ч а ю щ и и с   тем, что ведома  щестерн  при осевом перемещении между рабочей и холостой камерами измен ет объем .мас,ла рабочей камеры н, тем самым, регулирует производительность насоса, вне зависимости от числа оборотов.Subject matter and gear oil gear pump with a controlled capacity, which means that the driven mash when the axial movement between the working and idling chambers changes the volume. working chamber n, thereby, regulates the performance of the pump, regardless of the number of revolutions.
