Nylon inner gear ring elastic coupling
Nylon inner gear ring elastic coupling is used for flexible transmission between shafts, allowing large axial radial displacement and angular displacement, and has simple structure, convenient maintenance, easy disassembly and assembly, low noise, and low transmission efficiency loss. Advantages such as long service life.
轴孔型式有圆柱形(Y)、圆锥形(Z)和短圆柱形(J)。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。工作温度为-20～+70℃。每种形式均有10个规格，它们适用的轴孔直径d=6-100mm，轴孔长度L=16-212mm，公称转矩T=40-3150N.m，许用转速[n]=1800-6000r.min。
The main raw materials of nylon couplings are: engineering plastics, reinforced nylon double 6, nylon double 6 plus 30% glass fiber toughened.It has good mechanical and electrical properties, and can be toughened, reinforced, flame-retardant, modified, and improved heat resistance.
The semi-coupling is made of casting, cast iron HT20-40, cast steel ZG35Ⅱ, the shaft hole and keyway are made by drawing, and the inner gear coupling elastomer jacket can be selected from various hardness synthetic rubber grease rubber according to user requirements; enhanced Cast nylon elastomer and other materials.In order to meet the needs of various mechanical transformations and imported equipment spare parts, we can provide a variety of internal tooth-shaped elastic couplings, and can accept non-standard orders according to needs.

The characteristics and maintenance methods of gear couplingGear coupling is a kind of removable rigid coupling.It uses internal and external tooth meshing to realize the torque rotation and movement transmission between the two halves of the coupling. It is suitable for the transmission shaft system connecting two concentric shafts, and has the performance of relatively compensating the relative displacement of the two shafts.Its structure is shown in Figure XNUMX. It is composed of main parts such as inner gear ring, gear shaft sleeve and end cover. Generally, small-sized gear coupling end cover and inner gear ring can be integrated. ...The structure and application range of slider couplingThe slider coupling is also known as the metal cross slider coupling. Its slider is in the shape of a ring and is made of steel or alloy. The cross slider coupling is suitable for transmissions with low speed and large transmission torque.The slider coupling is composed of two shaft sleeves and a slider. ...
