Embodiment
Below in conjunction with the accompanying drawings, embodiment of the present utility model is described in detail, it is to be understood that this practicality
New protection domain is not limited by embodiment.
Explicitly indicated that unless otherwise other, otherwise in entire disclosure and claims, term " comprising " or its change
Change such as "comprising" or " including " etc. and will be understood to comprise stated element or part, and do not exclude other members
Part or other parts.
As shown in Figures 3 to 5, according to the specific bag of the oil collecting structure of the small end of connecting rod of the utility model embodiment
Include：Small end of connecting rod 4 and the small end of connecting rod oil trap 5 for being opened in the top both sides of small end of connecting rod 4 respectively, and connection small end of connecting rod
The oil guide groove 6 of 4 top both sides small end of connecting rod oil traps 5.Wherein, small end of connecting rod 4 is put by connecting rob bushing and piston pin with piston 6
Dynamic connection, small end of connecting rod oil trap 5 is opened in the top both sides of the small end of connecting rod 4 respectively, and is connected by oil guide groove 6, is used for
Lubrication is provided to connecting rob bushing and the guide structure opened up is designed, and it is small that lubricating oil falls back to connecting rod by piston cavity spill port 7
First 4, small end of connecting rod oil trap 5 is then introduced by the oil guide groove 6, then connecting rob bushing is introduced by small end of connecting rod oil trap 5
Inner surface, lubrication connecting rob bushing and piston pin.So as to improve the supply of connecting rod piston pin and connecting rob bushing lubricating oil, it is ensured that piston
Pin lubricates with bushing；Avoid opposing oscillatory influence piston pin and the lubrication of connecting rob bushing because piston and connecting rod.
Specifically, small end of connecting rod 4 is swung with piston 6 by connecting rob bushing and piston pin and is connected, connecting rob bushing and piston
Relative motion is sold, lubricating oil falls back to small end of connecting rod 4 by piston cavity spill port 7, is then incorporated into connecting rob bushing inner surface,
Lubricate connecting rob bushing and piston pin.
Small end of connecting rod oil trap 5 is opened in the top both sides of the small end of connecting rod 4 respectively, for providing lubrication to connecting rob bushing
And the guide structure opened up is designed, connecting rod swings at work, and piston cavity spill port 7 exists with small end of connecting rod oil trap 5
Piston aligns oil-feed in top dead centre and lower dead center.
As shown in Figure 6, it is preferred that the external diameter Φ of small end of connecting rod oil trap 5 is in the center on small end of connecting rod top, and its is small
