本发明提供了一种摩托车赛车链轮及其制造方法,其中摩托车赛车链轮,包括链轮盘体,所述链轮盘体上设置有轴孔和轮齿,所述链轮盘体上开设有多个第一减重孔和多个第二减重孔;所述链轮盘体的所有表面通过物理气相沉积法沉积有减摩涂层,所述减摩涂层由内至外依次为Cr层、AlCrN层和Al‑DLC层,其中,所述Cr层的厚度为0.4‑0.5μm,所述AlCrN层的厚度为0.6‑0.7μm,所述Al‑DLC层的厚度为1.1‑1.4μm;所述链轮盘体的两个盘面上均贴附有碳纤维贴片,所述链轮盘体的两个盘面均下沉形成用于安装所述碳纤维贴片的沉台,所述碳纤维贴片固定嵌装在所述沉台上。本发明提供了一种综合性能优异的摩托车赛车链轮,其摩擦系数低,耐磨性能好。

    Provided in the present invention are a chain wheel of a racing motorcycle and a manufacturing method therefor. The chain wheel of a racing motorcycle comprises a chain wheel disc body, wherein an axle hole and wheel teeth are formed on the chain wheel disc body, and a plurality of first weight-lightening holes and a plurality of second weight-lightening holes are formed on the chain wheel disc body; an anti-friction coating is deposited on all the surfaces of the chain wheel disc body by means of a physical vapor deposition method, and the anti-friction coating sequentially comprises a Cr layer, an AlCrN layer and an Al-DLC layer from inside to outside, the Cr layer having a thickness of 0.4-0.5 μm, the AlCrN layer having a thickness of 0.6-0.7 μm, and the Al-DLC layer having a thickness of 1.1-1.4 μm; and carbon fiber patches are attached to both disc faces of the chain wheel disc body, the two disc faces of the chain wheel disc body both sink to form sunken tables used for mounting the carbon fiber patches, and the carbon fiber patches are fixedly embedded in the sunken tables. The present invention provides a chain wheel for racing motorcycles that has good comprehensive properties, and the chain wheel has a low friction coefficient and good wear resistance.
