組合導(dǎo)線輪（瓷輪）：應(yīng)用于漆包線或絲線適量導(dǎo)向，其中部瓷圈由精密陶瓷制作，凹槽超精拋光達(dá)Ra0．2，瓷圈配高速軸承，兩側(cè)的擋板可防止繞線時(shí)漆包線跳出槽外，同時(shí)使繞線時(shí)的張力保持穩(wěn)定一致，也有直接由全陶瓷與高速軸承組合的叫陶瓷瓷輪。適用于各類(lèi)繞線機(jī)及紡織機(jī)械中的過(guò)線過(guò)絲部件。

1、主體為精密陶瓷
2、護(hù)套采用尼龍材料
3、水中使用可選用石墨代替軸承

The wire roller is commonly used component when wire passing is required,it can be used in coil winding machine and the textile machinery as well.

The porcelain ring is mounted on the bearing,it will rotate by the thread and wire passing on the surface of the ring.Thus the sliding friction has been converted to the static friction.But at the start and stop,in order to overcome the inertia,there will be a partial sliding friction.

The surface polish degree of the porcelain ring reaches Ra0.2;
