Title:
CRUSHING SURFACE PART MEMBER
Document Type and Number:
Japanese Patent JP3807734
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To prevent the crack of a roller main body caused by a discontinuous clad cross-sectional shape, peeling of a hardened clad metal and fall-out becoming problems when the thickness of the hardened clad metal is changed according to abrasion.
SOLUTION: An undercut part 12 continuous in the crushing direction is provided on the part of a base material surface subjected to remarkable abrasion in the direction orthogonal to the crushing direction. Ribs 13 consisting of a material having inferior abrasion resistance to the hardened clad metal are attached in the crushing direction with prescribed spaces. A first abrasion resistant hardened metal 14a is filled for cladding between the adjacent ribs 13 and 13 to bury the undercut part. A second abrasion resistant hardened metallic material is clad over the whole crushing surface on the first metallic material 14a.
