Description

Известны шестеренчатые насосы внутреннего зацеплени , примен емые преимущественно дл  подачи масла.Internal gearing gear pumps are known that are mainly used to supply oil.

Предлагаемый шестеренчатый насос отличаетс  применением в нем устройства дл  уплотнени  торцовых зазоров, позвол юшего предотвратить утечку масла при работе на высоких давлени х.The proposed gear pump is characterized by the use of a device in it to seal the end gaps, to prevent oil leakage when operating at high pressures.

На фиг. I изображен насос в разрезе по Л -А на фиг. 2; на фиг. 2 - то же, в разрезе по - Б на фиг. I; на фиг. 3 - то же, в разрезе по В - В на фиг. 1; на фиг. 4 - то же, в разрезе по Г - Г на фиг. 3.FIG. I shows a pump in section along L-A in FIG. 2; in fig. 2 - the same, in a section on - B in FIG. I; in fig. 3 is the same, in section along B - B in FIG. one; in fig. 4 is the same, in a section along G - D in FIG. 3

Две сопр женные цилиндрические шестерни J и 2 с внутренним зацеплением торцовыми плоскост мисоприкасаютс  с уплотннтельнымн дисками .The two mating spur gears J and 2 with internal gearing with the face planes are missed to each other with sealing disks.

Диск 4 снабжен на ободе уплотнительным кольцом 5. Дл  уменьшени  потерь на трение вал 7 шестерни 2 и шестерн  1 в обойме 8 вращаютс  соответственно на игольчатых подшипниках 9 и 10.The disk 4 is provided with a sealing ring 5 on the rim. To reduce friction losses, the shaft 7 of the gear 2 and the gear 1 in the holder 8 are rotated respectively on needle bearings 9 and 10.

Дл  предотвращени  утечки масла через торцовые зазоры при высоких рабочих давлени х уплотнительный диск 4 выполнен подвижным в осевом направлении и прижимаетс  к торцам шестерен тарельчатой пружиной // и давлением нагнетаемой жидкости, подводимой из камеры нагнетани  через канал 12 в подвижном диске 4 (фиг. 4).To prevent oil leakage through the end gaps at high operating pressures, the sealing disk 4 is axially movable and pressed against the ends of the gears by a disk spring // and the pressure of the injected fluid supplied from the pressure chamber through the channel 12 in the movable disk 4 (Fig. 4) .

Рабочие шестерни 1 и 2, производ щие при вращении засасывание и нагнетание жидкости, и диски 3 и 4 заключены в кожух 13, который каналами 14 и 15 соединен соответственно со всасывающим и нагнетательным трубопроводами. Роль поршней, разобщающих всасывающую и нагнетательную полости, выполн ют зубцы шестерен 1 и 2. Камера нагнетани  отдел етс  от камеры всасывани  сегментом 16.The working gears 1 and 2, which produce suction and fluid injection during rotation, and the disks 3 and 4 are enclosed in a casing 13, which is connected by channels 14 and 15 respectively to the suction and discharge pipes. The role of the pistons separating the suction and discharge cavities is performed by gear teeth 1 and 2. The pressure chamber is separated from the suction chamber by segment 16.

При работе насоса жидкость засасываетс  из канала 14 и переноситс  зубь ми шестерен 1 и 2 в камеру нагнетани , откуда через канал 15 выталкиваетс  в нагнетательную магистраль. Одновременно жидкость из камеры нагнетани  по каналу 12 поступает в полость 17,When the pump is operating, the fluid is sucked from channel 14 and transferred by the teeth of gears 1 and 2 into the pressure chamber, from where it is pushed through channel 15 into the discharge line. At the same time, the fluid from the injection chamber through the channel 12 enters the cavity 17,
