瓷线轮用于漆包线改变方向及适量导向。其中间由精密陶瓷制作瓷圈,凹槽超精抛达Ra0.2,瓷圈内装有高速轴承,使漆包线与瓷圈之间的延迟滑动距离小于0.2mm,保护漆膜及保证漆包线的跳动在很小的范围之内。瓷线轮两侧的档板设计防止绕线时漆包线跳出,同时使绕线时的张力保持稳定
The ceramic roller is used for the direction changethe guidance of the enameled wire. The ceramic circle inside is made by the fine porcelain,the polish degree of the groove surface is Ra0.2. There is a high-speed bearing in the ceramic circle which can assure the lag sliding distance between the wirethe circle is no more than 0.2mm, thus the film has been protectedthe beating of the wire has been controlled within a certain small scope. The sidewalls of the ceramic roller can prevent the jump of the wire during the winding,stabilized the tension at the same time.
