GUIDE ROLLER AND PRODUCTION METHOD THEREFOR |
摘要 |
<p>Provided is a guide roller equipped with a roller body having surface roughness. The average value of the distance between the intersection points corresponding to the starting points and end points of roughness-curve crests, among the intersection points of roughness curves representing the surface roughness of the roller body and an average line for the roughness curves, is in the range of 0.2mm-1mm inclusive. The shape factor (K) defined by formula (1), said formula including the maximum trough depth (Rv) and the maximum height (Ry) of the roughness curves, is at least 0.7. Formula (1): K=Rv/Ry</p> |
