Abstract
The utility model provides a kind of engine link, includes connnecting rod big end, is provided with the axis hole of oval in configuration in this connnecting rod big end, and bearing shell is installed in this axis hole with interference fit.The axis hole of engine connecting rod big end is changed into oval in configuration by existing positive round configuration by the utility model, it is made just in time to become positive round from ellipse installing the distortion after bearing shell, the oil film between bearing shell will be made so effectively to set up, thus effectively can reduce the wearing and tearing of bearing shell, make the operation of device more stable, effectively.
Description
Technical field
The utility model relates to a kind of engine link, especially a kind of engine link on vehicular engine, and has the motor of this connecting rod.
Background technique
Along with adding of Abgasgesetz and fuel economy regulation is tight, the performance parameters such as the pressure of explosion of motor and power moment of torsion are improving constantly, thus more and more higher to the requirement of engine component.Connecting rod, as the heart part of motor, carries and reciprocating motion of the pistons is delivered to bent axle, converts the rotary motion of bent axle to, and then output torque, drives vehicle to travel.
As shown in Figure 1, the structural design of existing connecting rod 1 and bearing shell 4, normally the axis hole 3 of connnecting rod big end 2 is designed to be positive round configuration, and two panels connecting rod bearing shell 4 can be installed in the axis hole 3 of connnecting rod big end 2 by interference fit.In order to ensure bearing shell 4 can not in connnecting rod big end 2 axis hole 3 play, the external diameter of general bearing shell is designed to the shaft hole diameter being greater than connnecting rod big end, and magnitude of interference is probably diameter about 0.5mm.And connnecting rod big end 2 can be arranged on the connecting rod neck of bent axle, in order to avoid the dry friction of bearing shell and crankshaft journal, have lubricant film between bearing shell and crankshaft journal and exist, oil slick thickness is at about 0.005-0.015mm.
As shown in Figure 2, and after bearing shell 4 is installed, due to the existence of bearing shell magnitude of interference, the axis hole 3 of connnecting rod big end 2 has certain amount of deformation D, and amount of deformation D is generally 0.010-0.015mm, thus forms the axis hole 3' of an oval in configuration.And above-mentionedly mention oil slick thickness between normal connecting rod bearing shell and rod journal at 0.005-0.015mm, which results in oil film and can be affected foundation because of the amount of deformation of connnecting rod big end, or the oil film poor quality set up, oil film even can be made time serious to lose efficacy, bearing bush abrasion so also will be made to aggravate.Time serious, meeting and then cause connecting rod, bent axle to lose efficacy, finally causes whole power failure.
Therefore, a kind of novel engine link of necessary research and development, overcomes defect of the prior art.
Model utility content
The purpose of this utility model is to provide a kind of novel engine link, its bearing shell install after distortion, positive role can be played to the foundation of oil film.
To achieve these goals, the technical solution adopted in the utility model is as follows: a kind of engine link, and it includes connnecting rod big end, is provided with the axis hole of oval in configuration in described connnecting rod big end, and bearing shell is installed in described axis hole with interference fit.
Further, in the technical solution of the utility model, the major axis of the axis hole of described oval in configuration and the difference of minor axis are 0.010-0.015mm.
Further, in the technical solution of the utility model, the large bar of described connecting rod is connected with engine crankshaft, and the described shaft hole sleeve being wherein equipped with described bearing shell, on crankshaft journal, forms the lubricant film that thickness is 0.005-0.015mm between described bearing shell and crankshaft journal.
The utility model also provides a kind of motor, and it includes the engine link described in aforementioned one or more technological scheme.
Relative to prior art, the beneficial effects of the utility model are: the axis hole of connnecting rod big end is changed into oval in configuration by positive round configuration by the utility model, it is made just in time to become positive round from ellipse installing the distortion after bearing shell, the oil film between itself and bearing shell will be made so effectively to set up, thus effectively can reduce the wearing and tearing of bearing shell, make the operation of device more stable, effectively.

Embodiment
Below with reference to drawings and Examples, the technological scheme of a kind of engine link that the utility model relates to is described in further detail.
Refer to shown in Fig. 3 and Fig. 4, the mode of execution that the utility model relates to provides a kind of engine link of new structure, it includes connnecting rod big end 12, and is provided with axis hole 14 in connnecting rod big end 12, and bearing shell 20 is installed in this axis hole 14 with interference fit.Wherein, the axis hole 14 of this connnecting rod big end 12 is set to oval in configuration, and the difference process of its major axis and minor axis calculates and actual Sleeve assembling can obtain, and is generally 0.010-0.015mm.
During installation, as shown in Figure 4, two panels connecting rod bearing shell 20 is installed in the axis hole 14 of connnecting rod big end 12 by with interference fit.Due to the existence of bearing shell 20 magnitude of interference, the axis hole 14 of connnecting rod big end 12 has certain amount of deformation L, L is generally 0.010-0.015mm, thus makes the axis hole 14 of connnecting rod big end 12 just in time be deformed into the shape close to positive round by oval in configuration, axis hole 14' as shown in Figure 4.Like this, the oil film 30 between connecting rod bearing shell 20 and rod journal 10, effectively can be set up because of the amount of deformation of the axis hole 14 of connnecting rod big end 12, therefore also will play the effect of effectively lubricating to bearing shell 20, thus ensure that the effective, stable of structure.
Technical scope of the present utility model is not only confined to the content in above-mentioned explanation, those skilled in the art can under the prerequisite not departing from the utility model technological thought, various deformation and amendment are carried out to above-described embodiment, and these distortion and amendment all should be worked as and belonged in scope of the present utility model.
