The invention discloses a pulley capable of warning the abrasion degree of a pulley groove and a machining method of the pulley, and relates to the technical field of use and production of pulleys. The pulley comprises a bearing and a pulley body, a pulley groove is formed in the outer circle side of the pulley body and comprises pulley groove walls on the two sides, the pulley groove walls comprise the inner pulley groove wall and the outer pulley groove wall, the contact portions of the pulley groove walls and a steel wire rope are called easy-to-wear portions A, the wall thickness of the easy-to-wear portions A is L, the easy-to-wear portions A are annular, and a plurality of coloring material filling holes are formed in the ring bodies of the easy-to-wear portions A on the left side and the right side. The coloring material filling holes are distributed in a point shape along the ring body and are filled with coloring materials; the distance between the bottom face of the coloring material filling hole and the inner wheel groove wall of the easy-to-wear part A is 20%-30% of the wall thickness L. The coloring material filling hole is a closed hole. Maintenance personnel can know the abrasion degree of the pulley by visually observing the color change of the steel wire rope, and waste caused by the fact that the off-line pulley does not reach the use limit can be prevented; and meanwhile, the production safety is also ensured.
本发明公开了一种可警示轮槽磨损程度的滑轮及其加工方法,涉及滑轮的使用与生产技术领域。该滑轮包括轴承与滑轮体,滑轮体外圆侧为轮槽,轮槽包括两侧的轮槽壁,轮槽壁包括内轮槽壁与外轮槽壁,轮槽壁与钢丝绳接触部位称为易磨损部A,其壁厚为L,易磨损部A呈环状,左右两侧的易磨损部A环体内部内设置有若干个着色物料填充孔,着色物料填充孔的布置方式为沿环体点状分布,其内部填充有着色物料;着色物料填充孔底面距离易磨损部A的内轮槽壁的距离为壁厚L的20%~30%,着色物料填充孔为闭合孔洞。本发明使维护人员通过目测钢丝绳颜色变化就可以了解滑轮的磨损程度,可以防止下线的滑轮还没有达到使用极限,造成浪费;同时还保证了生产安全。
