Abstract

The invention discloses an internal meshed cycloid gear pump. The internal meshed cycloid gear pump comprises an internal gear and an external gear. The internal meshed cycloid gear pump is characterized in that the internal gear comprises six teeth; the external gear comprises seven teeth; the internal gear is arranged in the external gear; the opposite tooth hollow parts of the internal gear and the external gear form a plurality of individual seal cavities; each seal cavity comprises an oil suction cavity and an oil pressing cavity which are arranged at interval. According to the pump, the problems that the gear pump is complex in structure, is inconvenient to use, and leaks oil frequently in the prior art can be solved; the internal meshed cycloid gear pump is simple in structure, is convenient to use, is high in use efficiency, and is good in seal property.

Description

A kind of internal messing cycloid gear pump
Technical field
The present invention relates to gear pump, particularly relate to a kind of internal messing cycloid 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.
Summary of the invention
In order to solve prior art middle gear pump, complex structure, uses inconvenience, often occurs the problem that leakage of oil situation occurs, and the invention provides a kind of structure simple, easy to use, utilization efficiency is high, the internal messing cycloid gear pump of good seal performance.
In order to solve the problem, the technical solution used in the present invention is:
A kind of internal messing cycloid gear pump, comprise internal gear and external gear, it is characterized in that: described internal gear comprises six teeth, described external gear comprises seven teeth, described internal gear is arranged in external gear, 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.
Aforesaid a kind of internal messing cycloid gear pump, is characterized in that: described oil sucting cavity and pumping cavity interval are arranged.
Aforesaid a kind of internal messing cycloid gear pump, is characterized in that: described internal gear adopts stainless steel material to make.
Aforesaid a kind of internal messing cycloid gear pump, is characterized in that: described external gear adopts stainless steel material to make.
Aforesaid a kind of internal messing cycloid gear pump, is characterized in that: described oil sucting cavity is identical with pumping cavity volume.
Aforesaid a kind of internal messing cycloid gear pump, is characterized in that: described Seal cage adopts stainless steel material to make.
The beneficial effect that the present invention reaches: internal messing cycloid gear pump of the present invention, described internal gear is arranged in external gear, 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.Along with the rotation of gear, the volume generation respective change of each oil sucting cavity and pumping cavity, thus complete the work of suction, force feed, simple and easy to use, efficiency is high, good airproof performance.
Accompanying drawing explanation
Fig. 1 is the structural representation of internal messing cycloid gear pump of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the invention will be further described.Following examples only for technological scheme of the present invention is clearly described, and can not limit the scope of the invention with this.
As shown in Figure 1, a kind of internal messing cycloid gear pump, comprise internal gear 1 and external gear 2, described internal gear 1 comprises six teeth, described external gear 2 comprises seven teeth, described internal gear 1 is arranged in external gear 2, 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 3 and pumping cavity 4.Described oil sucting cavity 3 and pumping cavity 4 interval are arranged.Described internal gear 1 adopts stainless steel material to make.Described external gear 2 adopts stainless steel material to make.Described oil sucting cavity 3 is identical with pumping cavity 4 volume.Described Seal cage adopts stainless steel material to make.
In sum, internal messing cycloid gear pump of the present invention, described internal gear 1 is arranged in external gear 2, 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 3 and pumping cavity 4.Along with the rotation of gear, the volume generation respective change of each oil sucting cavity and pumping cavity, thus complete the work of suction, force feed, simple and easy to use, efficiency is high, good airproof performance.
More than show and describe basic principle of the present invention, major character and advantage.The technician of the industry should understand; the present invention is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.Application claims protection domain is defined by appending claims and equivalent thereof.
