Abstract
The utility model discloses a kind of composite machine oil pump device, its structure is：Lubricating oil pump inside the shell is provided with driving gear, and driving gear is engaged with driven gear, driving gear and Oil pump drive gear and the coaxially connected fixation of driving gear shaft, and driven gear is connected with driven gear shaft.Main driven gear, wheel shaft and drive gear are assembled in engine body.Oil-in is cast with the side of lubricating oil pump connecting position in body；Oil-out is cast with above.Body is provided with lubricating oil pump positioning sleeve, and machine oil pump case is assembled with engine body by positioning sleeve, and machine oil pump case is fixed by bolt seal with body.Lubricating oil pump is assembled in one with engine body, constitutes lubricating oil pump fuel supply chamber with engine body by oil pump casing, and is not separately provided the outside that lubricating oil pump is assembled in body, can thus effectively reduce electromotor peripheral hardware space.The structure had both met electromotor design requirement, reduced electromotor overall volume again.
Description
Technical field
This utility model belongs to engine components, and in particular to a kind of composite machine oil pump device.
Background technology
Traditional engine oil pump is independently assemblied on the outside of electromotor, when certain form of electromotor needs to be equipped with
During the oil pump of big flow, while oil pump volume increases, the size of electromotor profile must also increase, and which adds
The difficulty that electromotor is matched with car load.The utility model proposes a kind of composite machine oil pump device, can either meet electromotor big
The flow of the design requirement of flow oil pump, i.e. oil pump increased, but the overall dimensions of electromotor are relative to be obviously reduced, to whole
Car maintenance reserves bigger service clearance, while also reducing the difficulty that electromotor is matched with car load.
The content of the invention
The purpose of this utility model is to provide a kind of composite machine oil pump device, can either meet electromotor high flow rate oil supply
Requirement, again cause electromotor overall dimensions it is relatively reduced.
Theory structure of the present utility model is as follows with technical scheme：Composite machine oil pump device has：Machine oil pump case, master
Moving gear, driven gear, driving gear shaft, driven gear shaft, Oil pump drive gear, positioning sleeve, engine body and spiral shell
Bolt etc..Lubricating oil pump inside the shell is provided with driving gear, and driving gear is engaged with driven gear, driving gear and lubricating oil pump sliding tooth
Wheel and the coaxially connected fixation of driving gear shaft, driven gear are connected with driven gear shaft.Driving gear, driven gear, master
Movable gear shaft, driven gear shaft and Oil pump drive gear are assembled in engine body.In engine body and lubricating oil pump
The side of connecting position is cast with oil-in；Oil-out is cast with above engine body with lubricating oil pump connecting position.
Oil pump driving gear and driven gear external toothing are arranged on lubricating oil pump inside the shell, and machine oil pump case passes through positioning sleeve
The installation site being accurately fixed on engine body, machine oil pump case are fixed by bolt seal with body.Such lubricating oil pump
The gear train of inside the shell constitutes a sealing space with engine body, and the sealing space is constituted in engine body oil-in side
Oil suction chamber, constitutes out oil pocket in engine body oil-out side.
The characteristics of this utility model and beneficial effect are：Lubricating oil pump is assembled in one with engine body, by lubricating oil pump
Housing constitutes lubricating oil pump fuel supply chamber with engine body, and is not separately provided the outside that lubricating oil pump is assembled in body, thus may be used
Effectively reduce electromotor peripheral hardware space.The structure had both met electromotor design requirement, reduced electromotor overall volume again.
Description of the drawings
Fig. 1 is this utility model principle and dimensional structure diagram.
Fig. 2 is the dimensional structure diagram of this utility model embodiment.
Specific embodiment
Structure of the present utility model is described further below in conjunction with accompanying drawing and by embodiment.
By taking four-cylinder diesel engine as an example, composite machine oil pump device, its structure is：Driving tooth is installed in machine oil pump case 1
Wheel 2, driving gear is engaged with driven gear 3, and driving gear and Oil pump drive gear 6 are coaxially connected with driving gear shaft 4 solid
Fixed, driven gear is connected with driven gear shaft 5.Driving gear, driven gear, driving gear shaft, driven gear shaft and
Oil pump drive gear is assembled in engine body 8, is cast with oil-feed with the side of lubricating oil pump connecting position in engine body
Mouth 8-1；Oil-out 8-4 is cast with above engine body with lubricating oil pump connecting position.
Engine body is provided with lubricating oil pump positioning sleeve 7, and machine oil pump case is assembled with engine body by positioning sleeve, machine oil
Pump case is fixed by the sealing of bolt 9 with engine body.
Machine oil pump case and engine body constitute a sealing space, in the sealing space with the oil-in and go out
Hydraulic fluid port correspondence is respectively equipped with oil suction chamber 8-2 and goes out oil pocket 8-3.
In composite machine oil pump device, the edge of machine oil pump case and engine body plane are coincide, by bolt by machine oil
Pump case is fixed with engine body sealing.When electromotor operates, Oil pump drive gear rotarily drives oil pump driving gear,
Oil pump driving gear rotarily drives the oil pump driven gear of external toothing.Survey in oil suction chamber, oil pump driving gear and driven
To reversely rotate, oil suction chamber volume increases gear as gear is moved to out-of-gear direction, and intracavity produces certain vacuum
Degree, machine oil are just sucked from engine body oil-in and are full of oil suction chamber.Gear rotation is brought the machine oil deposited by between cog into fuel-displaced
Chamber, engages as a fuel-displaced side gear is entered, and goes out the reduction of oil pocket volume, and oil pressure is raised, machine oil just Jing engine bodies oil-out
Into engine oil channel.
Composite machine oil pump device can according to matching electromotor need oil flow rate, to engine body and lubricating oil pump outside
The sealing space of shell composition is adjusted, it is ensured that the oil flow rate that electromotor needs.
