进口尼龙内齿联轴器(NL) 产品用途 Product use

尼龙内齿联轴器(NL)允许较大的轴向径向位移和角位移，鼓形齿式联轴器属于刚挠性联轴器，具有径向、轴向和角向等轴线偏差补偿能力，且具有结构简单，维修方便，拆装容易，噪声低，传动功效损失小，使用寿命长等优点

结构特点 Structural features

1.轴孔型式有圆柱形（Y）、圆锥形（Z）和短圆柱形（J）The shaft hole types are cylindrical (Y), conical (Z), and short cylindrical (J)

2.轴孔和键槽采用拉制成型，内齿形联轴器弹性体外套可根据用户使用要求选用各种硬度合成橡胶脂橡胶、增强铸型尼龙弹性体等材料 The shaft hole and keyway are formed by drawing, and the elastic sleeve of the inner toothed coupling can be made of various hardness synthetic rubber grease rubber, reinforced cast nylon elastomer, and other materials according to user requirements

3.主要失效形式是齿轮磨损，采用强制稀油润滑后，齿面磨损大幅度降低，磨损量是脂润滑的10%左右，循环稀油可带走轧辊端的轧制热量及轮齿摩擦产生的热量，防止了轮齿材料表面许用接触应力降低；齿面经渗碳淬火处理后，承载能力高；正常情况下，不会出现断齿现象，满足连续轧机工作特点的要求 The main form of failure is gear wear. After using forced thin oil lubrication, the wear of the tooth surface is significantly reduced, with the wear amount being about 10% of that of grease lubrication. Circulating thin oil can take away the rolling heat at the roller end and the heat generated by gear tooth friction, preventing the reduction of the allowable contact stress on the surface of the gear tooth material; After carburizing and quenching treatment, the tooth surface has high bearing capacity; Under normal circumstances, there will be no tooth breakage, which meets the requirements of the working characteristics of the continuous rolling mill

4.可齿的接触条件，提高传递转矩的能力，延长使用寿命。NL尼龙齿联轴器径向尺寸小，承载能力大，常用于低速重载工况条件的轴系传动，并经动平衡的NL尼龙齿联轴器可用于高速传动，如燃汽轮机的轴系传动 Tooth contact conditions improve the ability to transmit torque and extend service life. NL Nilong gear couplings have small radial dimensions and large load carrying capacity, and are commonly used for shafting transmission under low speed and heavy load conditions. Dynamically balanced NL Nilong gear couplings can be used for high-speed transmission, such as shafting transmission of gas turbines
