Abstract
The utility model discloses a connecting rod of an engine with the advantages of lower processing accuracy requirement, high positioning accuracy, reliable operation and long service life. The connecting rod of the engine comprises a connecting rod body and a connecting rod cover, wherein the connecting rod body is fixedly connected with the connecting rod cover through a bolt, a crankshaft journal bore is formed between the connecting rod body and the connecting rod cover, joint faces where the connecting rod body is in contact with the connecting rod cover are non-processing planes and take the shape of natural fracture and unevenness, and the joint faces of the connecting rod body and the connecting rod cover meshes with each other. The connecting rod is suitable for the connection of an engine crankshaft.
Description
Technical field
The utility model relates to a kind of connecting rod, relates in particular to a kind of connecting rod that is used on the motor.
Background technique
Connecting rod shank in the engine link adopts high-strength bolt to be connected with connecting rod cap, because engine link stressing conditions complexity when work, and be subjected to variation frequent, thereby the connection reliability of connecting rod shank and connecting rod cap is had higher requirement.And high-strength bolt is to fixedly connected with the bolt hole on the connecting rod cap by connecting rod shank, just can only rely on bolt hole to position, so the machining accuracy of bolt hole has been proposed very high request; And owing to the junction plane on connecting rod shank in the common engine connecting rod and the connecting rod cap is a processing plane, in running, be easy to generate the mutual slippage between the plane, thereby cause the dislocation of connecting rod shank and connecting rod cap, make the dimensional accuracy etc. in crankshaft journal hole be difficult to guarantee, thereby influencing bent axle normally moves, cause the generation of inordinate wear, influence working life.
The model utility content
The technical problems to be solved in the utility model provides that a kind of requirement on machining accuracy is lower, Location accuracy is high, the engine link of reliable, long service life.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:
The utility model comprises connecting rod shank and connecting rod cap, connecting rod shank is connected by bolt with connecting rod cap, form the crankshaft journal hole between connecting rod shank and the connecting rod cap, the junction plane that described connecting rod shank and connecting rod cap are in contact with one another is non-processing plane, be the nature uneven shape that ruptures, and the junction plane on connecting rod shank and the connecting rod cap is meshing with each other.
The utility model compared with prior art has following obvious advantage and good effect:
1, requirement on machining accuracy is lower.Because connecting rod shank and connecting rod cap junction plane adopt uneven of intermeshing fracture naturally in the utility model, can realize accurate location, thereby can reduce the machining accuracy of bolt hole.
2, the location is smart high, reliable.Because connecting rod shank adopts uneven of intermeshing fracture naturally with the connecting rod cap junction plane in the utility model, thus the connection reliability of the Location accuracy that has improved both when moving.
3, long service life.Because connecting rod shank and connecting rod cap junction plane adopt uneven of intermeshing fracture naturally in the utility model, in running, can adapt to complicated force request, the precision in the crankshaft journal hole of connecting rod shank and connecting rod cap formation is guaranteed, thereby avoid the generation of inordinate wear, improve working life.

Fig. 2 is the center section plan of Fig. 1;
Fig. 3 be among Fig. 2 A to view.
Embodiment
Below in conjunction with the drawings and the specific embodiments the utility model is described in further detail:
As shown in Figure 1 to Figure 3: the utility model comprises connecting rod shank 1 and connecting rod cap 2, connecting rod shank 1 is provided with mutual corresponding bolt hole 3,4 with connecting rod cap 2, be provided with bolt (not drawing among the figure) in the bolt hole 3,4, bolt is fixedlyed connected connecting rod shank 1 with connecting rod cap 2, thereby make and form crankshaft journal hole 5 between connecting rod shank 1 and the connecting rod cap 2, connecting rod shank 1 is respectively 6,7 with the junction plane that connecting rod cap 2 is in contact with one another, junction plane 6,7 is non-processing plane, be the nature uneven shape that ruptures, and the junction plane on the connecting rod shank 16 is meshing with each other with junction plane 7 on the connecting rod cap 2.
Claims (1)
1. engine link, comprise connecting rod shank and connecting rod cap, connecting rod shank is connected by bolt with connecting rod cap, form the crankshaft journal hole between connecting rod shank and the connecting rod cap, it is characterized in that the junction plane that described connecting rod shank and connecting rod cap are in contact with one another is non-processing plane, be the nature uneven shape that ruptures, and the junction plane on connecting rod shank and the connecting rod cap is meshing with each other.
