Shaanxi NL type nylon internal gear coupling
TAG
NL型尼龙内齿型联轴器适用于轴间及挠性转动，允许较大的轴向径向位移，具有结构简单、维修方便、拆装容易、噪声低、传动动效损失小、使用寿命长等优点。轴孔型式有圆柱形、圆锥形和短圆柱形。轴孔和键槽按 标准GB3852-83《联轴器轴孔和键槽形式及尺寸》的规定加工。工作温度计20~+700℃，扭矩范围40N·m-315N·m。
NL-type nylon internal gear coupling adopts casting, cast HT20-40, cast steel ZG35II, shaft hole and keyway are made by drawing, internal gear coupling elastomer jacket can be selected in various hardness according to user requirements Synthetic rubber, polyurethane glue and reinforced nylon elastomer and other materials.
NL-type nylon internal gear coupling operating temperature range: -180℃～+160℃(glass fiber rod) FRP solid tent pole glass fiber pipe is made of glass fiber reinforced material and polyester resin pultruded [FRP] glass fiber The rod has excellent performance and characteristics such as long life, light weight, high strength, good flexibility, beautiful appearance, insulation, and good comprehensive benefits.
