Abstract
The utility model discloses a connecting rod structure for balancing cylindricity deformation of a big end, which comprises a connecting rod big end and a rod body, wherein the connecting rod big end is connected with the rod body, an arc transition section is arranged at the joint of the connecting rod big end and the rod body, a triangular weight removing structure is arranged in the middle of the arc transition section, and reinforcing ribs are arranged on the side face of the arc transition section. The connecting rod structure has balanced stress distribution, unchanged rod body strength and more balanced integral deformation of the large end of the connecting rod.
Description
Technical Field
The utility model relates to the technical field of engines, in particular to a connecting rod structure for balancing cylindricity deformation of a large head.
Background
At present, in order to ensure the strength of a rod body, the weight removing width is almost the same as that of the rod body at the joint of the big end and the rod body of the connecting rod, but if the weight removing is insufficient, the stress at the joint is too concentrated, the wall thickness of the big end is too great than that of the joint, so that the deformation of the big end is unbalanced, the cylindricity is poor, and the gap between the connecting rod tiles is reduced, so that the tiles are burned.
Disclosure of Invention
Aiming at the problems, the utility model provides the connecting rod structure for balancing the cylindricity deformation of the big end, the stress distribution is balanced, the strength of the rod body is unchanged, and the whole deformation of the big end of the connecting rod is more balanced.
The utility model adopts the following technical scheme to realize the purposes:
the utility model provides a connecting rod structure of balanced big end cylindricity warp, includes connecting rod big end and shaft, the connecting rod big end with the shaft is connected, the connecting rod big end with the junction of shaft is equipped with the circular arc changeover portion, the middle part of circular arc changeover portion sets up triangle-shaped and removes heavy structure, the side of circular arc changeover portion is equipped with the strengthening rib.
Preferably, the triangle deduplication structure is an equilateral triangle deduplication structure.
Preferably, the height of the reinforcing ribs is 4.5-5.5 mm.
The beneficial effects of the utility model are as follows:
according to the connecting rod structure for balancing cylindricity deformation of the big end, the stress at the joint of the big end and the rod body of the connecting rod is reduced by 30%, the stress can be distributed to other places more uniformly, the strength of the rod body is unchanged due to the effect of the reinforcing ribs, the whole deformation of the big end of the connecting rod is more balanced, and the cylindricity is optimized by 20%.

FIG. 1 is a front view of a connecting rod structure for equalizing cylindricity deformations of a large head according to an embodiment of the present utility model;
fig. 2 is a side view of a connecting rod structure for equalizing cylindricity deformation of a large end according to an embodiment of the present utility model.
In the attached drawings, a 1-connecting rod big end, a 2-rod body, a 3-triangle weight removing structure and 4-reinforcing ribs.
Detailed Description
The present utility model will be described in detail with reference to fig. 1 to 2 and the detailed description.
Referring to fig. 1-2, the present embodiment provides a connecting rod structure for equalizing cylindricity deformation of a big end, including a big end 1 and a rod body 2, the big end 1 is connected with the rod body 2, the joint of the big end 1 and the rod body 2 is provided with an arc transition section, the middle part of the arc transition section is provided with a triangle weight removing structure 3, and the side surface of the arc transition section is provided with a reinforcing rib 4.
According to the connecting rod structure for balancing cylindricity deformation of the big end, the triangular weight-removing structure 3 and the reinforcing ribs 4 are arranged, so that the stress at the joint of the big end 1 and the rod body 2 is reduced by 30%, the stress can be more evenly distributed to other parts of the big end 1 and the rod body 2, meanwhile, the strength of the rod body 2 is unchanged due to the action of the reinforcing ribs 4, the whole deformation of the big end 1 of the connecting rod is more even, and cylindricity is optimized by 20%.
In this embodiment, the bottom side of the triangular de-duplication structure 3 is close to the connecting rod big head 1, and the top angle of the triangular de-duplication structure 3 is far away from the connecting rod big head 1.
In this embodiment, the triangular weight-removing structure 3 is an equilateral triangle weight-removing structure, and the transition part gradually transitions from shallow to deep. The height of the reinforcing ribs 4 is 5mm, so that the strength problem of the rod body 2 after the weight of the triangular weight-removing structure 3 is solved.
While the utility model has been described in detail with respect to specific embodiments thereof, it will be apparent to those skilled in the art that various modifications and improvements can be made thereto. Accordingly, such modifications or improvements may be made without departing from the spirit of the utility model and are intended to be within the scope of the utility model as claimed.
