Abstract
The utility model discloses a kind of oil pump structure, comprise front case, internal rotor, crescent spacer, external rotor and rear case; Rear case is fixedly connected with the exterior edge face of front case, and internal rotor and external rotor are arranged in the chamber that front case and rear case surround engagingly, is provided with oil inlet passage and oil discharge passage that at least one and described chamber connect on the interior edge face of front case.Described oil inlet passage forms by the radially oil inlet passage radially arranging along front case with along the axial axial fuel inlet passage arranging of front case, and described oil discharge passage forms by the radially oil discharge passage radially arranging along front case with along the axial axial oil discharge passage arranging of front case.Oil-feed, oil discharge passage are preferably one and be symmetrical arranged along the central axis of front case.The utility model oil pump does not need at the outside transport pipe of installing of oil pump, to be connected to each lubricating point separately, has shortened the piping length of lubrication system, has reduced the leakage point of oil circuit, guaranteed better the lubricated of each lubricating point, and mounting or dismounting is convenient.
Description
Technical field
The utility model relates to a kind of oil pump, particularly relates to various interior external gear type oil pumps, Swing line oil pump structure.
Background technique
Filler opening, the oil outlet of the oil pumps such as conventional interior external gear type oil pump, Swing line oil pump is separately positioned on the left and right side of oil pump central axis or away from oil pump interior edge face, during work, oil pump needs to install separately transport pipe and is connected to each lubricating point in gear box body for example.There is following defect in the oil pump of this structure: the first, and due to reasons such as the oil pump applying working condition having are relatively more severe, installing space is little, cause the transport pipe of installing easily to damage; The second, due to the connection of transport pipe, increased on the one hand the leakage point of oil circuit, when oil pump damages, must first remove more scavenge oil pump of transport pipe on the other hand, cause installing and keeping in repair very inconvenient.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of leakage point that can reduce oil circuit, thereby can guarantee better the lubricated of each lubricating point, and installs and maintenance oil pump structure very easily all.
For solving the problems of the technologies described above, the utility model adopts a kind of like this oil pump structure, comprises front case, internal rotor, crescent spacer, external rotor and rear case; Described rear case is fixedly connected with the exterior edge face of front case, described internal rotor and external rotor are arranged in the chamber that front case and rear case surround engagingly, are provided with oil inlet passage and oil discharge passage that at least one and described chamber connect on the interior edge face of front case.
As a kind of preferred implementation of the present utility model, described oil inlet passage forms by the radially oil inlet passage radially arranging along front case with along the axial axial fuel inlet passage arranging of front case, and described oil discharge passage forms by the radially oil discharge passage radially arranging along front case with along the axial axial oil discharge passage arranging of front case.
As another preferred implementation of the present utility model, described oil-feed, oil discharge passage are one and be symmetrical arranged along the central axis of front case.
Adopt after said structure, the utlity model has following beneficial effect:
The utility model by arranging after the oil inlet passage and oil discharge passage connecting with chamber on the interior edge face of front case, oil-feed, oil discharge passage can be directly connected to oil pump support for example on the tank wall of gear box body, avoided like this oil pump to connect with the transport pipe between lubricated pipeline, shortened the piping length of lubrication system, reduce the leakage point of oil circuit, thereby guaranteed better the lubricated of each lubricating point.
Because oil pump of the present utility model is without exterior line, do not need when mounted at the outside transport pipe of installing of oil pump, to be connected to each lubricating point separately, but be directly connected to oil pump support for example on the tank wall of gear box body by oil-feed, the oil discharge passage of oil pump, gear box body inside configures pipeline connection again to each lubricating point, therefore when scavenge oil pump more, can directly dismantle oil pump, and needn't remove pipeline, the installation of oil pump and maintenance are all very convenient.
The component that oil pump of the present utility model adopts are less, simple in structure, and cost of production is low, easy care.

Embodiment
Referring to a kind of oil pump structure shown in Fig. 1 to Fig. 5, comprise front case 1, internal rotor 2, crescent spacer 3, external rotor 4 and rear case 5; Described rear case 5 is fixedly connected with the exterior edge face 1-1 of front case 1 by bolt, described internal rotor 2 and external rotor 4 are arranged in the chamber 6 that front case 1 and rear case 5 surround engagingly, are provided with oil inlet passage 7 and oil discharge passage 8 that at least one and described chamber 6 connect on the interior edge face 1-2 of front case 1.
As a kind of preferred implementation of the present utility model, as shown in Figure 2,4, described oil inlet passage 7 forms by the radially oil inlet passage 7-1 radially arranging along front case 1 with along the axial axial fuel inlet passage 7-2 arranging of front case 1, and described oil discharge passage 8 forms by the radially oil discharge passage 8-1 radially arranging along front case 1 with along the axial axial oil discharge passage 8-2 arranging of front case 1.In the utility model, described oil-feed, oil discharge passage 7,8 also can be other structure, for example for running through the oblique perforation of front case interior edge face 1-2 and chamber 6, not shown in the figures.
As another preferred implementation of the present utility model, as shown in Figure 4, described oil-feed, oil discharge passage 7,8 are one and be symmetrical arranged along the central axis of front case 1.
As shown in Figure 5, when mounted, oil pump of the present utility model is directly installed on to oil pump support for example on the tank wall of gear box body 9 by bolt, oil-feed, oil discharge passage 7 on oil pump front case interior edge face 1-2,8 are directly communicated with the filler opening 9-1, the oil outlet 9-2 that offer on casing 9 tank walls respectively, when work, lubricant oil directly enters oil inlet passage 7 from filler opening 9-1, after internal rotor 2 and external rotor 4 engagement driving, lubricant oil is directly delivered to each lubricating point by oil outlet 9-2 from oil discharge passage 8.
