Abstract
The invention relates to a valve spring lower seat of an engine, which is disposed in a valve spring mounting hole and comprises a bottom plate (11) and a limiting flange (12), and the limiting flange (12) is clamped between the wall of the valve spring mounting hole and a valve spring and limits shifting of the valve spring in the horizontal direction. As the valve spring lower seat is designed into a structure with the upward flange, the valve spring cannot excessively vibrate left and right during movement to avoid damaging a valve oil seal, and the problem that excessive oil flows into a combustion chamber due to poor sealing of the valve oil seal and the engine is damaged is prevented.
Description
Technical field
The present invention relates to belong to the engine design field, relate in particular to stand structure under a kind of engine valve spring.
Background technique
Engine valve actuating mechanism is one of motor two great institutions, and valve spring is one of important spare part in the distribution device, and main effect is to make the valve return.Because valve spring is to adopt the Spring Steel Wire coiling of special processing to form, hardness is higher, if be directly installed on the valve spring hole of cylinder cap, cylinder cap will inordinate wear, so increase spring seat in the valve spring installation place.Common spring seat is a simple stalloy that is installed in valve spring mounting hole bottom.
Can reduce wearing and tearing though stalloy is set to cylinder cap, in the movement process valve spring in the seat of honour about the vibration, valve spring can not get spacing.Finally, the valve-spring surge valve oil seal of will damaging, it is unusual even loosening to make it surface abrasion, causes valve oil seal poorly sealed, and machine oil causes the motor burn oil along the engine valve stem firing chamber of bleeding, and influences engine performance.
Summary of the invention
The present invention has designed following of a kind of engine valve spring, and the existing valve spring of the technical problem of its solution is moved easy abrasion to valve oil seal in the valve spring hole, cause machine oil to get into engine chamber, influences the engine operation performance.
In order to solve the technical problem of above-mentioned existence, the present invention has adopted following scheme:
Following of a kind of engine valve spring; Following of said engine valve spring is arranged in the valve spring mounting hole; Following of said engine valve spring comprises base plate (11) and spacing flange (12), said spacing flange (12) be clamped in said valve spring install between hole wall and the said valve spring and to said valve spring skew in the horizontal direction carry out spacing.
Further, said spacing flange (12) is a close ring, and said close ring is positioned at the edge of said base plate (11).
Further, said spacing flange (12) external diameter and valve spring mounting hole internal diameter are complementary; The valve spring external diameter is less than spacing flange (12) internal diameter, with the assemblage gap of retained gas door spring.
Further, said base plate (11) is provided with lightening hole (13).
Further, said lightening hole (13) and the coaxial setting of said valve spring, the diameter of said lightening hole (13) is less than the internal diameter of said valve spring.
Further, the spacing flange (12) of following of said engine valve spring is through the disposable impact briquetting of press tool.
Further, the material of following of said engine valve spring is a steel.
Following of this engine valve spring is compared with following of available engine valve spring, has following beneficial effect:
(1) the present invention is owing to be designed to the structure with upper overturning to following of valve spring; Thereby keep valve spring to tremble about at the volley can not be excessively; In order to avoid valve oil seal is caused damage, thus prevent to cause too much machine oil flow into combustor because of valve oil seal is poorly sealed, damage motor.
(2) the present invention is owing to be provided with lightening hole on base plate, and this lightening hole can play the weight that reduces motor, and can play the effect that reduces manufacture cost.
Description of drawings
Fig. 1: the perspective view that engine valve spring of the present invention is following.
Description of reference numerals:
Following of 1-valve spring; 11-base plate; 12-spacing flange; 13-lightening hole.
Embodiment
Below in conjunction with Fig. 1, the present invention is further specified:
The spacing flange 12 that this valve spring is following 1 is through the disposable impact briquetting of press tool, and the flange size is guaranteed that by mould production and processing and the assembling on motor are all very convenient.
Valve spring is installed on following 1 of the valve spring of this band flange; Valve spring is positioned at the inboard of spacing flange 12; In the engine operation process, the spacing flange 12 around following 1 of the valve spring effectively limited valve spring about vibration, solved wear problem to the valve oil seal surface; See according to test and feedback result after sale, respond well.
In addition, base plate 11 is provided with lightening hole 13.Lightening hole 13 and the coaxial setting of valve spring, the diameter of lightening hole 13 are positioned on the base plate 11 to guarantee valve spring less than the internal diameter of valve spring forever.Therefore, every motor need use a large amount of valve spring following 1, thereby lightening hole 13 can play the weight that reduces motor, and can play the effect that reduces manufacture cost.
Combine accompanying drawing that the present invention has been carried out exemplary description above; Obvious realization of the present invention does not receive the restriction of aforesaid way; As long as the various improvement of having adopted method design of the present invention and technological scheme to carry out; Or design of the present invention and technological scheme are directly applied to other occasion without improving, all in protection scope of the present invention.
