Abstract

The utility model discloses a kind of internal messing involute gear pump, comprise internal gear and external gear, it is characterized in that: also comprise dividing plate, internal gear is provided with in external gear, the center of circle of described internal gear and external gear is not on the same center of circle, and form several independently Seal cage between described internal gear with each relative tooth low-lying area of external gear, described Seal cage comprises oil sucting cavity and pumping cavity, be provided with a dividing plate between described internal gear and external gear, oil sucting cavity and pumping cavity separate by described dividing plate.The utility model solves prior art middle gear pump, and complex structure, uses inconvenience, often there is the problem that leakage of oil situation occurs, provide a kind of structure simple, easy to use, can realize fast inhaling force feed, utilization efficiency is high, safe and reliable internal messing involute gear pump.

Description

A kind of internal messing involute gear pump
Technical field
The utility model relates to a kind of gear pump, particularly relates to a kind of internal messing involute gear pump.
Background technique
Gear pump is a certain amount of oil hydraulic pump that a mated gear gear motion completes the work of play force feed, is the conventional oil hydraulic pump in Hydraulic Power Transmission System.But current gear pump, complex structure, uses inconvenience, often occurs the generation of leakage of oil situation.
Model utility content
In order to solve prior art middle gear pump, complex structure, uses inconvenience, often occur that the problem that leakage of oil situation occurs, the utility model provide a kind of structure simple, easy to use, can realize fast inhaling force feed, utilization efficiency is high, safe and reliable internal messing involute gear pump.
In order to solve the problem, technical solution adopted in the utility model is:
A kind of internal messing involute gear pump, comprise internal gear and external gear, it is characterized in that: also comprise dividing plate, internal gear is provided with in external gear, the center of circle of described internal gear and external gear is not on the same center of circle, and form several independently Seal cage between described internal gear with each relative tooth low-lying area of external gear, described Seal cage comprises oil sucting cavity and pumping cavity, be provided with a dividing plate between described internal gear and external gear, oil sucting cavity and pumping cavity separate by described dividing plate.
Aforesaid a kind of internal messing involute gear pump, is characterized in that: described dividing plate adopts one block of swing link.
Aforesaid a kind of internal messing involute gear pump, is characterized in that: described pumping cavity and oil sucting cavity interval are arranged.
Aforesaid a kind of internal messing involute gear pump, is characterized in that: described internal gear volume is less than the volume of external gear.
Aforesaid a kind of internal messing involute gear pump, is characterized in that: form eight independently Seal cages between described internal gear with each relative tooth low-lying area of external gear.
Aforesaid a kind of internal messing involute gear pump, is characterized in that: described dividing plate adopts stainless steel material to make.
The beneficial effect that the utility model reaches: the utility model internal messing involute gear pump, described Seal cage comprises oil sucting cavity and pumping cavity, and be provided with a dividing plate between described internal gear and external gear, oil sucting cavity and pumping cavity separate by described dividing plate.Internal gear is driving wheel, and along with the rotation of internal gear, external gear also and then rotates, the volume generation respective change of each like this oil sucting cavity and pumping cavity, thus completes the work of suction, force feed, and simple and easy to use, efficiency is high, good airproof performance.
Accompanying drawing explanation
Fig. 1 is the utility model internal messing involute gear pump structural representation.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.Following examples only for clearly the technical solution of the utility model being described, and can not limit protection domain of the present utility model with this.
As shown in Figure 1, a kind of internal messing involute gear pump, comprise internal gear 1, external gear 2, dividing plate 3, internal gear 1 is provided with in external gear 2, the center of circle of described internal gear 1 and external gear 2 is not on the same center of circle, and form several independently Seal cage between described internal gear 1 with each relative tooth low-lying area of external gear 2, described Seal cage comprises oil sucting cavity 4 and pumping cavity 5, be provided with a dividing plate 3 between described internal gear 1 and external gear 2, described dividing plate 3 adopts one block of swing link.Oil sucting cavity 4 and pumping cavity 5 separate by described dividing plate 3.Described pumping cavity 4 and oil sucting cavity 5 interval are arranged.Described internal gear 1 volume is less than the volume of external gear 2.Eight independently Seal cages are formed between described internal gear 1 with each relative tooth low-lying area of external gear 2.Described dividing plate 3 adopts stainless steel material to make.
In sum, the utility model internal messing involute gear pump, described Seal cage comprises oil sucting cavity 4 and pumping cavity 5, is provided with a dividing plate between described internal gear 1 and external gear 2, and oil sucting cavity 4 and pumping cavity 5 separate by described dividing plate 3.Internal gear 1 is driving wheel, and along with the rotation of internal gear 1, external gear 2 also and then rotates, the volume generation respective change of each like this oil sucting cavity 4 and pumping cavity 5, thus completes the work of suction, force feed, and simple and easy to use, efficiency is high, good airproof performance.
More than show and describe basic principle of the present utility model, major character and advantage.The technician of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
