And cooling, lead to connecting rob bushing 1 inordinate wear, the generation of the fault such as connecting rob bushing 1 and piston pin 4 locking.
Content of the invention
Technical problem to be solved in the utility model is：There is provided a kind of electromotor connecting rob bushing, this connecting rob bushing energy
Enough collect enough lubricating oil supply supporting regions, extremely ground with the connecting rob bushing avoiding leading to because of supporting region lack of lubrication
The generation of the faults such as damage, connecting rob bushing and piston pin locking.
For solving above-mentioned technical problem, the technical solution of the utility model is：Electromotor connecting rob bushing, including：Including
Bush body, is provided with collection oilcloth oil structure in described bush body, described collection oilcloth oil structure includes：Bushing oil collecting hole, described
Bushing oil collecting hole is located at the side at described bush body top；Drainage trough, described drainage trough is located at the interior table of described bush body
On face and circumferentially disposed along described bush body, the upper end of described drainage trough is connected with described bushing oil collecting hole；Spreader groove,
On the inner surface of described bush body and the width along described bush body extends described spreader groove, described drainage trough
Lower end be connected with described spreader groove；Oil sump, described oil sump on the inner surface of described bush body, described bushing
Body be respectively arranged at two ends with described oil sump, the oil sump described in two is all connected with described spreader groove, described oil sump
It is provided with the opening in outside.
Improve as a kind of, described oil sump sets up along the both ends of described bush body, and be located at described cloth oil
The top of groove.
Improve as a kind of, the circular arc that described spreader groove upwarps in two ends.
Improve as a kind of, described collection oilcloth oil structure setting has two sets, two sets of described collection oilcloth oil symmetrical configuration settings.
Employ technique scheme, the beneficial effects of the utility model are：
Because spreader groove is communicated with bushing oil collecting hole by drainage trough, the two ends of spreader groove offer oil sump so that cloth
Oil groove not only can collect the lubricating oil flowing into from bushing oil collecting hole, and can collect the profit flowing into from oil sump at any time
Lubricating oil, thus spreader groove can collect enough lubricating oil, simultaneously as spreader groove prolongs along the width of bush body
Stretch, have sufficiently large cloth pasta to amass, lubricating oil sufficiently can be supplied the supporting region of bush body, small end of connecting rod has been effectively ensured
Lubrication and cooling, it is to avoid the inordinate wear of connecting rob bushing, the generation of connecting rob bushing and the faults such as piston pin locking.

Specific embodiment
In order that the purpose of this utility model, technical scheme and advantage become more apparent, below in conjunction with accompanying drawing and enforcement
Example, is further elaborated to this utility model.It should be appreciated that specific embodiment described herein is only in order to explain
This utility model, and it is not used in restriction this utility model.
As Fig. 3 and Fig. 4 is jointly shown, a kind of electromotor connecting rob bushing, including bush body 11, bush body 11 interior
Two collection oilcloth oil structures are arranged with surface.
Collection oilcloth oil structure includes：
It is opened in the bushing oil collecting hole 16 of the top side of bush body 11；
Drainage trough 13 on bush body 11 inner surface, drainage trough 13 sets along the circumference of bush body 11 inner surface
Put, its upper end is connected with bushing oil collecting hole 16；
Spreader groove 14 on bush body 11 inner surface, spreader groove 14 is arranged along the width of bush body 11,
The middle part of spreader groove 14 is connected with the lower end of drainage trough 13；
Oil sump 15 on bush body 11 inner surface, oil sump 15 is located at the two ends of bush body 11, two collection
Oil sump 15 is connected with the two ends of spreader groove 14 respectively, collects lubricating oil for convenience of oil sump 15, and oil sump 15 is provided with outer
The opening of side.
When collection oilcloth oil structure collects lubricating oil, not only when the spill port 31 of bushing oil collecting hole 16 and piston 3 is relative, energy
Enough collect piston 3 and splash the lubricating oil coming to spreader groove 14, and oil sump 15 can be collected from each position of electromotor (such as at any time
Piston cavity, piston cooling nozzle, crankshaft balance weight etc.) splash the lubricating oil of coming, thus spreader groove 14 can be collected enough
Many lubricating oil.Because spreader groove 14 extends along the width of bush body 11, therefore spreader groove 14 has sufficiently large cloth oil
Lubricating oil can sufficiently be supplied the supporting region of bush body 11, lubrication and the cooling of small end of connecting rod 2 have been effectively ensured by area,
Avoid the inordinate wear of connecting rob bushing 1, the generation of the fault such as connecting rob bushing 1 and piston pin 4 locking.
Wherein, oil sump 15 sets up along the end of bush body 11, positioned at the top of spreader groove 14, in order to oil-collecting
The lubricating oil flow that pond 15 is collected is in spreader groove 14.
Spreader groove 14 structure is the tip-tilted circular arc in two ends, and arc-shaped structure can increase the cloth pasta of spreader groove 14
Long-pending, also allow for the flowing of lubricating oil.
In sum, electromotor connecting rob bushing of the present utility model collects lubrication not only by bushing oil collecting hole
Oil, and lubricating oil can be collected by the oil sump at two ends, spreader groove can be collected enough lubricating oil supplies and carry
Area is so that supporting region can sufficiently be lubricated, it is to avoid the connecting rob bushing inordinate wear that leads to because of supporting region lack of lubrication,
The generation of the fault such as connecting rob bushing and piston pin locking.
The above is the citing of this utility model preferred forms, and the part wherein do not addressed in detail is this area
The common knowledge of those of ordinary skill.Protection domain of the present utility model is defined by the content of claim, any based on this reality
The equivalent transformation being carried out with new technology enlightenment, also within protection domain of the present utility model.
