Abstract
The utility model provides a valve spring seat of a motorcycle engine and belongs to the technical field of motorcycle components. The valve spring seat comprises a motorcycle engine valve spring seat main body which is integrally disc-shaped and comprises a lateral surface with two annular steps and a conical inner hole; the motorcycle engine valve spring seat main body is of a composite layer structure, and comprises a low-carbon alloy structural steel substrate layer and a surface carburization composite layer; an included angle alpha between the side edge and central vertical line of the conical inner hole is 18-22 degrees; and the thickness of the surface carburization composite layer is 0.1-0.3mm. Compared with the prior art, the product developed by the utility model has the following beneficial effects: the product is of a composite layer structure; after being subjected to quenching treatment, the product is good in abrasive resistance, strong in compression resistance, guaranteed in product quality and long in service life; and the included angle alpha between the side edge and central vertical line of the conical inner hole is 18-22 degrees, so that the conical inner hole can be more tightly adhered to the peripheral conical surface of a valve collet, the contact area is enlarged and the stability is guaranteed.
Description
Technical field
The utility model is a kind of cotter seat, and particularly a kind of motorcycle engine air valve spring seat belongs to the motorcycle part technical field.
Background technique
The motorcycle engine air valve spring seat is the vitals of motorcycle engine, and in the use, its interior sidewall surface and motorcycle engine valve locker outer side surface are fitted.Motorcycle engine air valve spring seat commonly used comprises motorcycle engine air valve spring seat main body, and the integral body of described motorcycle engine air valve spring seat main body is disc, and it comprises with the outer side surface of 2 ring-shaped steps and cone-shaped endoporus.Original product adopts low-carbon alloy structural steel to make, and product is not wear-resisting, crushing resistance is low, and it is short that deformation, poor stability, working life easily occur.
The model utility content
The purpose of this utility model is in the above-mentioned prior art, the motorcycle engine air valve spring seat not wear-resisting, crushing resistance is low, easily generation deformation, poor stability, shortage in working life fall into, a kind of new motorcycle engine air valve spring seat is provided, the wear resistance that can realize product is good, crushing resistance is strong, is difficult for occuring the purpose of deformation, good stability, long service life.
The technological scheme taked of the utility model is to achieve these goals: a kind of motorcycle engine air valve spring seat, comprise a kind of motorcycle engine air valve spring seat main body, the integral body of described a kind of motorcycle engine air valve spring seat main body is disc, and it comprises with the outer side surface of 2 ring-shaped steps and cone-shaped endoporus; Described a kind of motorcycle engine air valve spring seat main body is lamination layer structure, and it comprises low-carbon alloy structural steel base layer and case-carbonizing composite bed, and the thickness of described case-carbonizing composite bed is 0.1-0.3mm; The angle α of the side of described cone-shaped endoporus and center vertical line is 18-22 °.
The thickness of described case-carbonizing composite bed is 0.2mm.Surface hardness reaches HR15N86-91, and the low-carbon alloy structural steel base layer is 20CrMo steel base layer.
The angle α of the side of described cone-shaped endoporus and center vertical line is 20 °.
Compared with prior art the utility model development beneficial effect is:
(1) described product is lamination layer structure, and it comprises 20CrMo steel base layer and case-carbonizing composite bed, and after Quenching Treatment, the wear resistance of product is good, crushing resistance is strong, guaranteed, the long service life of quality of product;
(2) the angle α of the side of described cone-shaped endoporus and center vertical line is 18-22 °, makes itself and valve collet external conicity face applying degree tightr, and area of contact increases, and guarantees its stability.
