小齿轮采用黄铜(Brass)材质的居多。达亿瓦、迪佳等品牌的旗舰产品采用不锈钢,也有使用合金的。黄铜作为小齿轮的材料是比较合适的,与质硬的主齿轮配合使用,有助于改善顺滑度,耐用度也不错。因为小齿轮的齿实际上是一排连续的齿绕在轴心上,对材料的要求不像主齿轮单个齿的要求高。也正是由于黄铜小齿轮相对较软的缘故,导致对主齿轮的要求可 Pinion brass (Brass) the majority of materials. Tatsu billion, Di Jia brands such as the flagship product using stainless steel, but also the use of alloy. Brass as a pinion gear material is more appropriate, and hard with the main gear used to help improve the smoothness, durability is not bad. Because the pinion gear teeth are actually a row of continuous teeth on the shaft, the material requirements are not as high as the main gear of a single tooth requirements. It is also due to the relatively soft brass pinion, resulting in the main gear requirements can be
