As preferably, described roller skin unit is made up of high-carbon system super abrasive alloy-layer and medium carbon structure steel layer.
As preferably, described roller skin unit is respectively arranged with roller skin radially inner side plane and roller skin screwed hole.
As preferably, described roller skin unit is also provided with dismounting screwed hole.
As preferably, described roller skin radially inner side plane and roller skin screwed hole are arranged on carbon structure steel layer radially inner side plane, and described dismounting screwed hole is arranged on carbon structure steel layer side end face.
As preferably, described roller skin unit is two or more.
As preferably, described roller is provided with roller heating endoporus, roller shoulder and roller radial outside plane; Described roller shoulder is provided with roller through hole.
As preferably, described main shaft, to be connected by flat key between roller and roller skin.
Two of object of the present invention is the assembly method providing a kind of roll system structure.
Technical scheme is: a kind of assembly method of roll system structure, comprises the following steps:
Use flat key by roller and spindle mounted; Assembled by roller shoulder and main shaft shoulder and form axial location;
Use screw rod to insert roller through hole in advance, use a pair nut to be screwed into the roller radially inner side screw thread of screw rod, form double nuts structure and locking positioning mutual to screw rod;
Roller skin unit uses flat key, and is coordinated with roller radial outside plane by radially inner side plane;
Use screw rod to be screwed into roller skin screwed hole by roller through hole, use double nut that screw rod is screwed into roller through hole, complete roller skin location.
Compared with prior art, beneficial effect of the present invention is:
Roller of the present invention connects interference hot assembly on main shaft by key, and the radial inner cylinder machined of roller has locating shoulder, step assembling and positioning corresponding on main shaft.High-wear-resistant alloy roller skin is coordinated with roller radial outside plane by radially inner side plane, by and connected by key, bolt connection provides circumferential, radial location respectively.When part is changed in maintenance, only need dismounting roller skin can realize the fast quick change part of roller skin, maintenance.
It is extremely rapid that the present invention changes part, and working life is high.Under the prerequisite solving traditional type roller skin replacing maintenance work inefficiency problem; high-wear-resistant alloy roller skin is adopted significantly to improve roller skin working life; shorten shutdown change the part time thus greatly improve production efficiency, thus efficiently solve the problem that traditional type roller skin working life is short, change part inefficiency.

Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described.
As shown in figures 1-8, a kind of high-pressure roller mill close-coupled fast assembling-disassembling wear resistant roll architecture, comprises main shaft 1, roller 2 and roller skin 3.Roller skin 3 is detachable, and roller skin 3 is made up of six pieces of roller skin unit.Roller skin unit is made up of high abrasion composite casting alloy material.
Main shaft 1 is provided with main shaft shoulder 1a.
Roller 2 profile appearances is hexagonal cylindricality, and inner is hollow cylinder chamber formation roller heating endoporus 2a, and both ends of the surface have roller shoulder 2b.Its radial outline six planes, the equal machined of radial inner cylinder have mating surface, are respectively used to assembling high abrasion roller skin and roller owner axle.Roller shoulder 2b radial direction is drilled with roller through hole 2c, forms assembly relation with high abrasion roller skin, and radial outline six planes are roller radial outside plane 2d.Roller 2 material is middle carbon cast steel.
Every block roller skin unit is 1/6th flat fan-shaped, and its radial outer material is high-carbon system super abrasive alloy, and its radial inner layer material is medium carbon structure steel.Medium carbon structure steel layer radially inner side plane machined roller skin radially inner side plane 3a peace keyway, in order to implement the location between roller 2, attack roller skin screwed hole 3b in the axial both sides of medium carbon structure steel layer radially inner side plane, use bolt and roller boss to be connected to form assembly relation.Attack dismounting screwed hole 3c at medium carbon structure steel layer radial side end face, for dismantle time for installing lifting bolt.
During installation, use flat key 6 roller 2 and main shaft 1 to be assembled, assembled by roller shoulder 2b and main shaft shoulder 1a and form axial location.Use screw rod 4 to insert roller through hole 2c in advance, use a pair nut 5 to be screwed into the roller radially inner side screw thread of screw rod 4, formation double nuts structure locking positioning mutual to screw rod.Roller skin unit uses flat key 6, and coordinated with roller radial outside plane 2d by radially inner side plane 3a, screw rod 4 is used to be screwed into roller skin screwed hole 3b by roller through hole 2c, double nut is used screw rod to be screwed into roller through hole 2c, complete roller skin location, adopt same way to implement assembling to six pieces of roller skin unit and form full circumferences.
The present invention is solving under the prerequisite of inefficiency problem that high-pressure roller mill roller skin changes part maintenance work, and roller skin material adopts high-wear-resistant alloy significantly to improve roller skin working life, shortens shutdown and changes the part time thus greatly improve production efficiency.
