Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described.
As shown in figs 1-9, the quickly dismantled wear resistant roll architecture of a kind of high-pressure roller mill, comprises main shaft 1, roller 2, roller skin 3 and pressure ring 4.Outwardly convex bottom roller skin 3 two ends, roller skin 3 is detachable, and roller skin 3 is made up of three pieces of roller skin unit.
Main shaft 1 is provided with main shaft shoulder 1a.
Roller 2 material is carbon structural steels, roller 2 is provided with roller shoulder 2b.Roller 2 profile appearances is the flanged (FLGD) cylindrical sleeve in two ends, and inside is hollow cylinder.Its outer surface and the equal machined mating surface of inner surface, be respectively used to assembling high abrasion roller skin and roller owner axle.Its flange axial drilling, forms assembly relation with high abrasion roller skin and heats endoporus 2a.Flange is provided with the roller flange face 2c that coordinate skin-deep with roller, and flange and roller skin-deep company on one end have roller through hole 2e, the other end have roller screwed hole 2d.
Every block roller skin unit is one third sector shaped, and radial cross-sectional shape is top, lower hollow two ends symmetry is outwardly.Its radial outer material is high-carbon system super abrasive alloy, and inner layer material is medium carbon structure steel.Medium carbon structure steel layer is respectively equipped with roller skin locating flange end face 3a, roller skin location roller screwed hole 3b, roller skin end face 3c, roller skin conical surface 3d and roller skin location pressure ring screwed hole 3e.Roller skin locating flange end face 3a is mutually vertical with roller skin end face 3c, and roller skin conical surface 3d and roller skin end face 3c in one plane.Medium carbon structure steel layer is also provided with dismounting screwed hole 3f, for dismantle time for installing lifting bolt.This some holes and face are formed in the following manner: medium carbon structure steel layer radially inner side cylinder machined mating surface, keyway, in order to implement the location between roller 2, at medium carbon structure steel layer end face tapping female bore, form assembly relation with roller end flanges.Also process the conical surface at medium carbon structure steel layer, and at side end face, the conical surface large footpath tapping female bore, adopt screw assembling mode to coordinate with high-strength press annular tapering.
