Abstract
The utility model relates to a valve spring of an engine of a diesel engine. According to the technical scheme provided by the utility model, the valve spring comprises a spring body formed by a spring steel wire, wherein the top end part of the spring body has conical degree; both the supporting surface of the top end of the spring body and the supporting surface of the bottom end of the spring body are flat; the angle of the supporting surface of the top end is 270-330 degrees, the angle of the supporting surface of the bottom end is 270-330 degrees, and the thickness of the tail end of thetop end of the spring body is 0.25-0.4 time of the diameter of the spring steel wire. The valve spring leads the stress to be distributed uniformly and the risk factor of the fatigue fracture to be lowered greatly and reduces the volume and weight of the spring while the size of the upper seat of the spring is reduced; moreover, the valve spring can be steadier in compression process, thereby reducing the vibration.
Description
Technical field
The utility model relates to a kind of valve spring of using on diesel engine.
Background technique
Along with expanding economy, people are more and more higher to the requirement of diesel engine, and valve spring is as the part of a key of motor, and updating, it is frequent also more and more to trend towards.Vehicle service condition valve spring of motor in driving process is born high loading, high-frequency motion, and normal condition is issued to 2000～3000 to be changeed, even higher.Therefore under the working state of so high requirement, all be very high challenge to valve spring material and project organization.Present diesel engine valve spring adopts the steel wire of circular cross-section usually, and valve spring integral body is cylindrical.
This valve spring, stress distribution are not too even, and the risk factor of fatigue fracture is big, whole valve spring cylindrical, and the spring volume is big, Heavy Weight and increased the size at the spring seat of honour, and the vibration that this spring produces in compression process is bigger.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, a kind of valve spring of diesel engine is provided, so as to make stress distribution evenly, the risk factor of fatigue fracture reduces greatly, the size at the minimizing of spring volume and weight saving, the spring seat of honour is dwindled, more steady in compression process, vibration is littler.
The technological scheme that provides according to the utility model, the valve spring of described diesel engine, comprise the spring body that forms by Spring Steel Wire, spring body tip portion has tapering, the top supporting surface and the bottom supporting surface of spring body are plane, and the angle of top supporting surface is 270～330 °, and the angle of bottom supporting surface is 270～330 °, and tail end, spring body top thickness is 0.25～0.4 times of the Spring Steel Wire diameter.
Perpendicularity≤2 of the axis of spring body and top supporting surface or bottom supporting surface °.Spring Steel Wire section ovalize.
The utility model stress substep is even, and the risk factor of fatigue fracture reduces greatly, has also dwindled the size at the spring seat of honour when having alleviated the spring volume and weight, and is more steady in compression process, reduces generation of vibration.
Description of drawings
Fig. 1 is a plan view of the present utility model.
Fig. 2 is a plan view of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with concrete drawings and Examples.
As shown in the figure: the valve spring of described diesel engine comprises the spring body 1 that is formed by Spring Steel Wire, spring body 1 tip portion has tapering, the top supporting surface 1a and the bottom supporting surface 1b of spring body 1 are plane, and the angle of top supporting surface 1a is 270～330 °, the angle of bottom supporting surface 1b is 270～330 °, and tail end, spring body 1 top thickness is 0.25～0.4 times of the Spring Steel Wire diameter.
Perpendicularity≤2 of the axis of spring body 1 and top supporting surface 1a or bottom supporting surface 1b °.Spring Steel Wire section ovalize.
The cross section is that oval-shaped Spring Steel Wire design makes the stress substep more even, and the risk factor of fatigue fracture reduces greatly; Spring body 1 tip portion has tapering, has also dwindled the size at the spring seat of honour when having alleviated the spring volume and weight; More steady in spring body 1 compression process, reduce generation of vibration.
It is linear that the rounded cylindrical spring characteristic line of section is, and the length of spring compressed of the present utility model with tapering is after begin that the spring coil contact is arranged, and it is non-linear that characteristic line becomes, and the natural frequency of vibration is a variate, and the anti-resonance ability is traitorous strong apart from pressure spring.Good stability, compact structure.
