Abstract
The utility model relates to a marine engine connecting rod, in particular to the marine engine connecting rod for solving the problem of easily generated friction and collision between the position near a big end bolt hole of the existing connecting rod and other parts. The marine engine connecting rod comprises a connecting rod small end and a connecting rod big end integrated with the connecting rod small end into one whole body through a rod body. A shoulder part of the connecting rod big end, which is close to the rod body, is downwards provided with an inclined plane. In the utility model, by changing a big end structure of the connecting rod, the friction and collision between the connecting rod and other parts in the operating process of an engine are avoided. The marine engine connecting rod has a reasonable structure and high working efficiency, generates low sound and has long service life.
Description
Technical field:
The utility model relates to a kind of marine engine parts, relates in particular near a kind of solved the existing connnecting rod big end bolt hole and rubs easily with other component and the marine engine connecting rod of collision problem.
Background technique:
Engine link is one of critical component of marine engine, and its effect is that the to-and-fro motion with piston changes rotatablely moving of bent axle into, and the pressure that acts on the piston set is passed to bent axle.So connecting rod is bearing very high periodic shock power, bending force and inertial force at work.This just requires connecting rod to have good performance.Existing connecting rod is in the process of compact type engine running, when certain angle of swing of bent axle, the gap is very little near its stud bolt hole and between other component, friction and collision take place in easy and miscellaneous part, produce noise and metal fragment, influence the performance of motor, even cause the breakage of engine components.
Summary of the invention:
The purpose of this utility model is to overcome and solves the deficiencies in the prior art and a kind of rational in infrastructure, high working efficiency, the marine engine connecting rod little, long service life of sounding are provided.
For reaching above-mentioned purpose, the technical solution of the utility model is: comprise connecting rod small end, make the connnecting rod big end of one by shaft and connecting rod small end, it is characterized in that: have an inclined-plane that tilts at connnecting rod big end downwards near the shoulder of shaft.
Connnecting rod big end is provided with crank fitting seat and the connecting rod cap that links together by bolt.
The utility model compared with prior art has following advantage: (one) goes a part of material to be the inclined-plane near the bolt hole of crank fitting seat less, increased the gap between connecting rod and other component on the one hand, friction and collision have been reduced, and this structure of one side does not influence the performance of connecting rod, and is rational in infrastructure; (2) be because the gap between connecting rod and other component increases, friction and collision have been avoided, reduced the running resistance of connecting rod and bent axle, increased working efficiency, the sound that has sent when having reduced work, also reduce the breakage of connecting rod and near component simultaneously, prolonged the working life of connecting rod and motor.
Description of drawings
Fig. 1 improves the structural representation of front rod.
The structural representation of Fig. 2 marine engine connecting rod of the present utility model.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
As shown in the figure, a kind of marine engine connecting rod comprises connecting rod small end 1, makes the connnecting rod big end 5 of one by shaft 2 and connecting rod small end 1, it is characterized in that: have an inclined-plane 6 that tilts at connnecting rod big end 5 downwards near the shoulder of shafts 2.Connnecting rod big end 5 is provided with crank fitting seat 3 and the connecting rod cap 4 that links together by bolt.
Crank fitting seat 3 is bolted to connection with connecting rod cap 4, near a part of material of pruning crank fitting seat 3 bolts hole, be the inclined-plane, increased the gap between connecting rod and other component, so just avoided friction and collision between the connecting rod and other component in engine operation process.
