Abstract
The utility model discloses a connecting rod assembly of a diesel engine. The connecting rod assembly comprises a connecting rod; the connecting rod comprises a connecting rod bearing cap and a connecting rod body; the cracking surface of each of the rod bearing cap and the connecting rod body is a cracking surface with a bevel incision; the small end of the connecting rod is stepped, a sleeve is pressed into the small end of the connecting rod, and a connecting rod bearing bush positioning groove is formed in the large end of the connecting rod and is round. The connecting rod assembly of the diesel engine is reasonable in structural design; the connecting rod bearing cap is exactly and effectively connected through the rough cracking surface formed through the cracking technology; the stepped small end of the connecting rod makes full use of the effective space, so that the stress distribution is relatively reasonable; the round connecting rod bearing bush positioning groove provides accurate positioning for a connecting rod bearing bush.
Description
Technical field
The utility model relates to a kind of diesel engine connecting bar assembly.
Background technique
General diesel engine is because crankshaft main journal diameter is larger, so the boundary dimension of connnecting rod big end is larger, wants can take out from cylinder block upper end connecting rod shank when dismounting, must adopt angular cut connecting rod.Connecting rod mounts cover while being incorporated on connecting rod shank and must strictly locate, to prevent connecting rod cap lateral displacement.Owing to bearing compared with large shearing force, easily there is fatigue ruption in the connecting-rod bolts of angular cut connecting rod.For this reason, should adopt the localization method that can bear transverse force, adopting at present more is sawtooth localization method, and the sawtooth of broaching out on connecting rod shank and connecting rod cap junction plane relies on the flank of tooth to realize located lateral.This kind of localization method advantage is that sawtooth surface of contact is large, and laminating closely.Shortcoming is that requirement on machining accuracy is higher, and after the assembling of connecting rod and connecting rod cap, has residual stress and stay connecting rod ASSY, and has increased processing cost.
Model utility content
The purpose of this utility model is exactly in order to address the above problem, and a kind of diesel engine connecting bar assembly is provided, and it has the useful space of making full use of, the rational advantage of distribution of force.
To achieve these goals, the utility model adopts following technological scheme:
A kind of diesel engine connecting bar assembly, it comprises connecting rod, described connecting rod comprises connecting rod bearing cap and connecting rod shank, the section that rises of connecting rod bearing cap and connecting rod shank is the angular cut formula section that rises, the microcephaly of described connecting rod is ladder-type, in the microcephaly of described connecting rod, be pressed with lining, the major part of connecting rod is provided with connecting rod bearing shell locating slot.
Described connecting rod bearing shell locating slot be shaped as circle.
The beneficial effects of the utility model: the utility model reasonable in design, the coarse section that rises that connecting rod bearing cap forms by the breaking process that rises forms the effective connection fitting together perfectly, the connecting rod small end of ladder-type makes full use of the useful space, distribution of force is more reasonable, and circular connecting rod bearing shell locating slot is located for connecting rod bearing shell provides accurately.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the utility model connecting rod small end schematic diagram;
Fig. 3 is the utility model connecting rod bearing shell locating slot.
Wherein, 1. connecting rod shank, 2. connecting rod bearing cap, 3. lining.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail.
As Fig. 1, a kind of diesel engine connecting bar assembly, it comprises connecting rod, described connecting rod comprises connecting rod bearing cap 2 and connecting rod shank 1, connecting rod bearing cap 2 and connecting rod shank 1 form the angular cut formula section that rises by the breaking process that rises, the microcephaly of connecting rod is ladder-type, is pressed with lining 3 in the microcephaly of connecting rod, is provided with circular connecting rod bearing shell locating slot in the big end hole of connecting rod.
The section that rises of angular cut accurately joins the mating face of connecting rod bearing cap 2 and connecting rod shank 1, guarantees firm location accurately.
The microcephaly of connecting rod is ladder-type, is pressed with lining 3 in the microcephaly of connecting rod, has improved the bearing capacity of connecting rod, and distribution of force is more reasonable.
In the big end hole of connecting rod, process circular connecting rod bearing shell locating slot, make bearing shell more accurate positioning.
Although above-mentioned, by reference to the accompanying drawings embodiment of the present utility model is described; but the not restriction to the utility model protection domain; one of ordinary skill in the art should be understood that; on the basis of the technical solution of the utility model, those skilled in the art do not need to pay various modifications that creative work can make or distortion still in protection domain of the present utility model.
Claims (2)
