Utility model content
Technical problem to be solved in the utility model is: provide a kind of electromotor Oil injection cooling structure, existing to solve
The technical problem that piston can not be cooled down by the cooling system of some electromotors.
For solving above-mentioned technical problem, the technical solution of the utility model is: electromotor Oil injection cooling structure, including institute
Stating the body of electromotor, be provided with oil groove at the main bearing seat of described body, described oil groove connects the oil duct of described body, described machine
Being positioned on body at described oil groove and be provided with nozzle, described nozzle is provided with nozzle opening, sends out described in the port of export correspondence of described nozzle
The piston of motivation.
Improving as one, described nozzle is stepped, and the entrance point external diameter of described nozzle is more than the outlet of described nozzle
End external diameter, described body offers the nozzle installing hole suitable with described nozzle form.
Improve as one, between centrage and the longitudinal section of described body of described nozzle, be provided with angle.
Improving as one, described oil groove is arc-shaped.
After have employed technique scheme, the beneficial effects of the utility model are: due to electromotor Oil injection cooling structure
Including the body of described electromotor, being provided with oil groove at the main bearing seat of described body, described oil groove connects the oil duct of described body,
Being positioned on described body at described oil groove and be provided with nozzle, described nozzle is provided with nozzle opening, and the port of export of described nozzle is corresponding
The piston of described electromotor, thus the lubricating oil in body oil duct can enter the nozzle opening of nozzle by oil groove, then from nozzle
The port of export spray to piston, utilize the pressure injection of lubricating oil to take away the heat of piston specific part, piston carried out effectively
Cooling, prevents high temperature fault, thus meets the requirement that engine power increases substantially；Processing oil groove on body, makes simultaneously
Oil groove connection body oil duct, and on body install nozzle, volume is little, it is not necessary to exterior line, can save supercharging oil duct,
The casting of pressurized nozzle, process and install, complete machine is changed little, easily realizes；Being easy to complete machine arrange, space is flexible.
Owing to described nozzle is stepped, the entrance point external diameter of described nozzle is more than the port of export external diameter of described nozzle, institute
State and on body, offer the nozzle installing hole suitable with described nozzle form, use transition or interference fit to be installed on by nozzle
In nozzle installing hole so that assembling simplicity.
Owing to being provided with angle between centrage and the longitudinal section of described body of described nozzle, by changing angle, permissible
Make the different parts lubricating oil cooled piston that nozzle sprays, meet the cooling requirement of piston.

Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing and enforcement
Example, is further elaborated to this utility model.Should be appreciated that specific embodiment described herein is only in order to explain
This utility model, is not used to limit this utility model.
As Fig. 1 to Fig. 3 jointly shown in, a kind of electromotor Oil injection cooling structure, including the body 1 of electromotor, body 1
Being provided with oil groove (not shown) at main bearing seat 11, oil groove is arc-shaped, and the double dot dash line in Fig. 1 shows the processing of oil groove
Position, is adding man-hour, and milling cutter can be used to be processed oil groove, and the oil duct 12 of oil groove connection body 1, body is provided with lubrication
Oil inlet 13, the hollow arrow in Fig. 1 represents the trend of lubricating oil, body 1 is positioned at oil groove and is provided with nozzle 2, on nozzle 2
Being provided with nozzle opening 21, the piston (not shown) of the corresponding electromotor of the port of export 23 of nozzle 2, i.e. the port of export 23 of nozzle 2 refers to
To the piston of electromotor.
In order to make assembling easy, nozzle 2 is stepped, outside entrance point 22 external diameter of nozzle 2 is more than the port of export 23 of nozzle 2
Footpath, body 1 offers the nozzle installing hole 14 suitable with nozzle 2 shape, uses transition or interference fit to be installed by nozzle 2
In nozzle installing hole 14.
Preferably, between centrage and the longitudinal section of body 1 of nozzle 2, it is provided with angle, by changing angle, spray can be made
The different parts of the lubrication oil cooled piston of mouth 2 injection, meets the cooling requirement of piston.
Its operation principle is as follows:
Lubricating oil in the oil duct 12 of body 1 can enter the nozzle opening 21 of nozzle 2, then going out from nozzle 2 by oil groove
Mouth end 23 sprays to piston, utilizes the pressure injection of lubricating oil to take away the heat of piston specific part, carries out the coldest to piston
But, prevent high temperature fault, thus meet the requirement that engine power increases substantially；Processing oil groove on body 1, makes oil simultaneously
The oil duct 12 of groove connection body 1, and nozzle 2 is installed on body 1, volume is little, it is not necessary to exterior line, can save pressurised oil
Road, the casting of pressurized nozzle, process and install, complete machine is changed little, easily realizes.
The electromotor Oil injection cooling structure that this utility model provides, utilizes the pressure injection of lubricating oil to take away piston specific
The heat at position, effectively cools down piston, prevents high temperature fault, thus wanting of meeting that engine power increases substantially
Ask；Complete machine is changed little simultaneously, easily realize；Being easy to complete machine arrange, space is flexible.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all at this
Any amendment, equivalent and the improvement etc. made within the spirit of utility model and principle, should be included in this utility model
