采用优质碳素结构钢进行冲压成型。
表面进行了喷吵、电镀处理。
采用先进的铣齿加工工艺,使齿形更精确。
链轮整体进行了调质热处理,极大地提高了其综合机械性能,使链轮的耐磨性显著提高。
齿部硬化:需要提高齿端强度和磨损寿命的场合,推荐使用齿端硬化链轮。各个尺寸小齿数的机械用碳素钢轮毂切削规格,齿端部均实施硬化处理。
齿部无硬化:齿端不实施硬化处理。链轮大齿数范围的齿端均为无硬化规格。
正确选用链轮型号。
检查安装传动链轮的位置状态是否良好,否则须检修或更换相关件。
按正确方法将主、从动链轮安装到位,且锁紧紧固件使其达到规定力矩要求。
装上链条并调整好松紧度后,检查链条与链轮配合是否顺畅、共面,且与链罩无干涉。
从动链轮应有张紧装置。
链轮和链条最好同时更换,若只更换其中之一,会加剧双方的磨损。
由于主动链轮转速高、齿数少,在相同条件下,比从动轮磨损快些,属正常情况。
要定期地清洁及润滑传动链条、传动链轮,以提高其使用寿命。
镀锌:镀锌是以提高金属的防锈性能为目的的表面处理工艺。随着钴酸盐纯化处理的进步,外观性能也有了很大的提高。
化学镀镍:化学镀镍的耐腐蚀性能、耐磨损性能提高,镀镍过程中不通电、无电解。适合使用在形状复杂、尺寸精度要求高的产品上。
发黑处理(表面氧化):即碱性发黑处理,将金属置于碱性处理液中加热,金属本身起化学作用,在其表面形成黑色皮膜,皮膜具有防锈效果。
磷化处理:即磷酸盐处理。将金属浸入加温后的磷酸盐溶液中进行化学处理,使金属表面形成磷酸盐保护膜。

注:1.*表示无键槽。
2.键槽对齿尖。
3.“t”表示键槽和螺孔呈90°和180°。
4.齿部硬化有助于增加链条和链轮的使用寿命,24齿以下较小的链轮,转速超过600R/min建议做齿部硬化处理。
