Connecting rod structure for balancing cylindricity deformation of large end

The utility model discloses a connecting rod structure capable of balancing cylindricity deformation of a large head, which comprises a connecting rod large head and a rod body, the connecting rod large head is connected with the rod body, an arc transition section is arranged at the joint of the connecting rod large head and the rod body, a triangular de-weighting structure is arranged in the middle of the arc transition section, and a reinforcing rib is arranged on the side surface of the arc transition section. The connecting rod structure is balanced in stress distribution, the strength of the rod body is not changed, and the overall deformation of the connecting rod big end is more balanced. 本实用新型公开了一种均衡大头圆柱度变形的连杆结构，包括连杆大头和杆身，连杆大头和杆身相连接，连杆大头和杆身的交接处设有圆弧过渡段，圆弧过渡段的中部设置三角形去重结构，圆弧过渡段的侧面设有加强筋。本实用新型的连杆结构应力分布均衡，杆身强度不变，连杆大头的整体变形更加均衡。
