Abstract
The utility model discloses a lower arranged valve rotating mechanism of an internal combustion engine. The utility model comprises a body, a flat spring, and a rotary spring, wherein the rotary spring is arranged in an annular groove of the body; one surface of the flat spring compacts the rotary spring; the body is a base which is arranged on the lowest surface; an opening of the annular groove of the base is upward; a cover cap is arranged on the flat spring; the edge portion on the flat spring abuts on a step surface of the cover cap, and the lower end of the cover cap is fixedly connected with the edge of the base. The lower arranged valve rotating mechanism of an internal combustion engine is changed from the previous tensile stress subjected state to the compression stress subjected state; axial dimensions are shortened; weight of the whole component is favorable for being lightened; good rotary effects can be obtained; structure is simple; production efficiency is favorable for being increased, and production cost is reduced.
Description
Technical field
The utility model relates to a kind of valve rotating mechanism of internal-combustion engine, relates in particular to a kind of down valve rotating mechanism of internal-combustion engine simple in structure, belongs to the internal combustion engine part manufacture field.
Background technique
The valve rotating mechanism of internal-combustion engine is a kind of a kind of assembly that cylinder of internal-combustion engine covers that is installed in, the valve rotating mechanism of existing internal-combustion engine is top load arrangement, as by Zhang Shengyi in disclosed utility model patent of May 10 nineteen ninety-five application, on October 30th, 1996, its name is called " engine valve pressure rotating machinery ", and the patent No. is: CN95241589.5.The valve rotating mechanism of this internal-combustion engine is made up of body, retainer, planar spring and rotating spring, wherein the taper hole of body and valve collet outer cone match, variation by valve spring elastic force size causes planar spring generation resiliently deformable, thereby force helical spring generation canting, wriggling, make the body rotation.The shortcoming of the valve rotating mechanism of this internal-combustion engine is: (1) axial dimension is big, and the weight of whole assembly is big, and internal-combustion engine is when high speed rotating, and its movement inertia is big, can influence the reliability of valve system; (2) main body structure is comparatively complicated, and the manufacture cost height is unfavorable for enhancing productivity and saving cost, and the difficulty that new machine is transformed is bigger, is unfavorable for the marketing of product.
Summary of the invention
The purpose of this utility model is exactly the down valve rotating mechanism that a kind of simple in structure, internal-combustion engine that weight is lighter is provided in order to address the above problem.
In order to reach above purpose, the utility model is realized in the following ways:
The utility model comprises body, planar spring and rotating spring, rotating spring places in the annular groove of body, the one side of planar spring is pressed rotating spring, described body is a base, base is positioned at the bottom, and the annular groove opening of base upwards is provided with cover cap on described planar spring, the top edge section of planar spring is near the step surface of cover cap, fixedlys connected with the edge of base in the lower end of cover cap.
In actual use, the utility model is installed on the cylinder head of internal-combustion engine, the valve stem of internal-combustion engine passes by the endoporus of base, place the valve spring of valve stem upper end to be pressed on the step surface of cover cap, in the time of the valve open and close, size variation will take place in the elastic force of valve spring, thereby cause planar spring generation resiliently deformable near the cover cap step surface, oppressing helical spring again topples over, wriggles, thereby promote planar spring, cover cap rotation, and then drive valve spring, cotter seat, valve collet, valve rotation.
The beneficial effects of the utility model are:
Because the utility model changed the compression chord state into by the former tensile stress state that is subjected to, axial dimension shortens, so help alleviating the weight of whole assembly, reaches better rotate effect, and simple in structure, helps enhancing productivity, and reduces production costs.
Description of drawings
Accompanying drawing is a sectional structure chart of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is done further specific descriptions:
As shown in drawings, the utility model comprises body, planar spring 2 and rotating spring 3, rotating spring 3 places in the annular groove of body, the one side of planar spring 2 is pressed rotating spring 3, and body is a base 4, and base 4 is positioned at the bottom, the annular groove opening of base 4 upwards, be provided with cover cap 1 on planar spring 2, the top edge section of planar spring 2 is near the step surface of cover cap 1, fixedlys connected with the edge of base 4 in the lower end of cover cap 1.
In actual use, the utility model is installed on the cylinder head of internal-combustion engine, the valve stem of internal-combustion engine passes by the endoporus of base, place the valve spring of valve stem upper end to be pressed on the step surface of cover cap 1, in the time of the valve open and close, size variation will take place in the elastic force of valve spring, thereby cause planar spring 2 generation resiliently deformables near the step surface of cover cap 1, oppressing helical spring 3 again topples over, wriggles, thereby promote planar spring 2, cover cap 1 rotation, and then drive valve spring, cotter seat, valve collet, valve rotation.
