State on the implementation before the technology, the production and processing of flange and bearing ring part is according to the specification requirement of using, process routinely and method of inspection tissue batch acknowledgment copy, the flange of welding usefulness is selected Fine Steel Casting iron for use No. 45, and bearing ring is selected GCr15 high-quality bearing steel for use
Flange endoporus tolerance is the H7 level, and bearing ring external diameter tolerance is the h6 level, and both roughness all should be more than 1.6 grades.Be provided with the groove of scarfweld silk in the flange endoporus, its dark width is controlled at 0.4～0.8mm according to product standard and type.
The main characteristics of the present invention are to select cored solder wire for use, use the heat treatment heating means, once finish into the xenogenesis steel, for example the welding of medium carbon steel and bearing steel.This technology mainly is embedded between flange and the bearing ring interface by extraordinary cored solder wire, under certain high temperature, both reached the purpose of weldering pricker silk fusing, reached the requirement of strength after product quenches again, and therefore selected the cored solder wire of special type very important flange and the firm welding of lasso.The weldering solder of selecting for use should have good fusing point and flowability, quickens the atom diffusion between the interface, can fully fill up two slits between the interface; Under hot conditions, have non-volatilely, can not dissociate and evaporated toxin compound, stable physical performance and mechanical strength are arranged behind the compound boundary because of the fusing of weldering solder.This technology selects for use cored solder wire to belong to the silver-bearing copper welding wire, wherein silver content is 40～45% weight, copper content is 40～50% weight, all the other are zinc, tin and other trace elements, make welding wire in heat-treatment furnace, form molten state, in flange and lasso interface, produce the capillary adsorbed state, reduce the fusing point at interface, make the top layer, interface at high temperature quicken the diffusion velocity of interface atom, reach mutual infiltration and form the strong bonded interface.
Select suitable scaling powder in the fusion weld process for use, for example no-clean scaling powder is coated on the weld interface of cored solder wire, be used to clean activated interfaces, promote the phase counterdiffusion of weld interface atom, to stablizing the fused mass chemism, raising weld interface intensity and toughness effect are very big, scaling powder can be selected the hydrazine hydrochloride class for use, alcohol hydrazine class and epoxy resin add copper, zinc, the glass putty furnishing adhesive with good wettability and flowability, are coated in equably on the joint interface, forgive dried standby.
Flange and bearing ring tolerance fit are also very important, both should adopt the interference tolerance between the interface, can not be loose excessively, can not tension, cross pine then when quench hot, because material shrinks the welding fluid that causes melting and runs off, influence firm welding, tension then be press-fitted or pyroprocess in make product deformation effect product quality, therefore flange cooperates with the bearing ring precision and will get well, and the flange id tolerance that preparation is used for this technology is H6, and the bearing ring tolerance is h5, must control the tolerance dimension of every parts, to guarantee the finished product rate.
