Description
Technical field
The present invention relates to a kind of wear-resisting DTA flywheel shaft pulley, belong to technical field of mechanical equipment.
Background technology
DTA flywheel shaft pulley is one of important composition parts, and its performance quality directly affects strander production capacity
Performance, the consumption of power, stable working and the service life of other related components.GT3/G2 crosses sth. made by twisting pulley in work
In, owing to running up, at its working surface, abrasion easily occurs thus cause seminess.
Summary of the invention
The technical problem to be solved is to provide a kind of wear-resisting DTA flywheel shaft pulley.
Wear-resisting DTA flywheel shaft pulley, is closed by the hollow cylindrical sandwich layer of both ends open and the hard being positioned at sandwich layer periphery
Gold wearing layer composition, described hard alloy abrasion-resistant layer surface is U-type groove shape.
As priority option, described hard alloy abrasion-resistant layer includes the composition of following mass percent: Mo:28-40%,
Cr:3.2-6%, C:0.3-2.3%, Mn:1-5%, Cu:0.5-3%, Si:0.3-5%, N:0.2-2.4%, remainder is ferrum.
As preference, described hard alloy abrasion-resistant layer is to be deposited over above sandwich layer by deposition techniques.
The preparation method of described wear-resisting DTA flywheel shaft pulley, comprises the steps:
One), flux-cored wire is prepared: described flux-cored wire skin material is carbon steel or rustless steel, and remaining powder is by mixed powder machine
Mixing and within 2-3 hour, be fabricated to flux-cored wire, the composition of whole flux-cored wire is Mo:28-40%, Cr:3.2-6%, C:0.3-2.3%,
Mn:1-5%, Cu:0.5-3, Si:0.3-5%, N:0.2-2.4%, remainder is ferrum；The a diameter of 2.4mm of described flux-cored wire；
Two), cylindric sandwich layer being heated up to 220-250 DEG C, the flux-cored wire then step one prepared is by regulation electric current heap
It is welded in sandwich layer periphery, then will be welded with the sandwich layer outer wrap insulation material of flux-cored wire, after being incubated ten hours and get final product.
As preference, in described step 2, electric current is between 180-185 ampere.
As preferably, the material of described substrate core is steel.
The Advantageous Effects of the present invention: base steel core and novel hard alloy are combined in one by the way of deposition
Rising, novel hard alloy composition includes Mo, Cr, C, Mn, Cu, Si, N, Fe, simultaneously containing a large amount of Mo elements in composition, in friction
Time become the product of oxide of Mo, the presence of which can have certain lubrication, solve alignment after shell-rinding wheel contact surface
The phenomenon of the abrasion that device pulley the most easily occurs, thus the working cycle of swage wheel after extending shell-rinding wheel, solve
The defect of its frequent failure, decreases the consumption of swage pulley after shell-rinding wheel, has saved cost.
Accompanying drawing explanation
Fig. 1, wear-resisting DTA flywheel shaft pulley structure schematic diagram, 1, cylindric sandwich layer, 2-wearing layer, 3-U shape groove.
Detailed description of the invention
The present invention is described in further detail with detailed description of the invention below in conjunction with the accompanying drawings:
In Fig. 1, wear-resisting DTA flywheel shaft pulley, by the hollow cylindrical sandwich layer of both ends open and be positioned at the hard of sandwich layer periphery
Matter alloy wear-resisting layer forms, and described hard alloy abrasion-resistant layer surface is U-type groove shape.
Hard alloy abrasion-resistant layer of the present invention includes the composition of following mass percent: MO:28-40, Cr:3.2-6%,
C:0.3-2.3%, Mn:1-5%, Cu:0.5-3%, Si:0.3-5%, N:0.2-2.4%, remainder is ferrum.
Embodiment 1,
One), preparing flux-cored wire: described flux-cored wire skin material is carbon steel, remaining powder was by mixed powder machine mixing 2-3 hour
Being fabricated to flux-cored wire, the composition of whole flux-cored wire is Mo:28%, Cr:3.2%, C:0.3%, Mn:1%, Cu:0.5%, Si:
0.3%, N:0.2%, remainder is ferrum；The a diameter of 2.4mm of described flux-cored wire;
Two), by cylindric sandwich layer being heated up to 220 DEG C, the flux-cored wire then step one prepared is welded in by regulation electric current heap
Sandwich layer periphery, then will be welded with the sandwich layer outer wrap insulation material of flux-cored wire, after being incubated ten hours and get final product.
Embodiment 2
One), preparing flux-cored wire: described flux-cored wire skin material is rustless steel, remaining powder is little by mixed powder machine mixing 2-3
Time be fabricated to flux-cored wire, the composition of whole flux-cored wire is Mo:40%, Cr:6%, C:2.3%, Mn:5%, Cu:3%, Si:5%,
N:2.4%, remainder is ferrum；The a diameter of 2.4mm of described flux-cored wire;
