Current major factory being produced on by common iron by Quenching Treatment using take-up main shaft pulley.But severe Under operating mode, easily abrasion causes the failure modes such as crackle to its working face.The CR12MOV materials of existing process, integrally finish it Being quenched afterwards, product is to make steel wire rope, because the hardness of steel wire rope is higher, when work, friction, product Running speed is also very fast, therefore abrasion is very big, and general service life was at 7-15 days or so.
Therefore, so as to influenceing its production status.At present, take-up main shaft pulley can improving performance have very big space.
The content of the invention
In view of the deficiencies of the prior art, the present invention provides a kind of take-up main shaft pulley.
In order to realize appeal purpose, concrete technical scheme of the invention is as follows：
A kind of take-up main shaft pulley, including ring-type wheel disc substrate sandwich layer and the high temperature resistant of ring-type wheel disc substrate sandwich layer periphery it is resistance to Grind layer;Described heat resistant and wear resistant layer outer surface is arc groove.
As preference：The heat resistant and wear resistant layer includes the raw material of following mass percents：Mo:36-44%,Cr:7- 12%,Mn:3-7%,Si:0.5-3.5%,Ni:3-8%,C:1-4%,Ti：0.3-1.2%, surplus Fe.
As preference：The heat resistant and wear resistant layer is that hard alloy is cast in into ring-type wheel disc substrate by casting process Sandwich layer periphery.
As preference：The preparation method of the heat resistant and wear resistant layer is as follows：Ring-type wheel disc substrate sandwich layer is put into preparation In good mould, then the various raw materials of heat resistant and wear resistant layer are well mixed in proportion and are heated up to 1600 ° into liquid-state casting In mould, the mould cast is placed 10 hours, takes out, its surface is finished, produced.
As preference：The material of the ring-type wheel disc substrate sandwich layer is 42# chrome molybdenums or 35# chrome molybdenums.
As preference：The arc groove depth 2mm, the thickness of heat resistant and wear resistant layer is 3.5mm.
The advantageous effects of the present invention：42# chrome molybdenums or 35# chrome molybdenum base cores and novel hard alloy are passed through into casting Mode be combined together, novel hard alloy composition includes Mo, Cr, Mn, Si, Ni, C, Fe, while contains a large amount of Mo in composition Element, in friction into Mo oxide product, the presence of which can have certain lubrication to contact surface, solve receipts The phenomenon for the abrasion that line main shaft pulley easily occurs at work, so as to extend the work period of take-up main shaft pulley, solve The defects of its frequent failure, reduce the consumption of take-up main shaft pulley, saved cost.
