Embodiment
The embodiment of the present invention is as shown in Fig. 2 to 5, the processing method of the turbocharger collar thrust bearing, turbocharging
Device collar thrust bearing as shown in figure 1, by left side annular carrier 1 and right hand sleeves 2 be integrally connected and constitute, carrier left end
With a carrying end face A coordinated with plane bearing, the band level endoporus being interference fitted with turbine wheel shaft, the present embodiment four are set in sleeve
With being provided with one and turbine wheel shaft boss at sleeve connection in level endoporus cylindrical interference fits at different levels corresponding with turbine wheel shaft 3, carrier
Stop axially position, the turbocharger thrust collar axle in one of annular step of camshaft in the inner face C of overhead, inner face top
Hold procedure of processing following (long measure millimeter in figure)：
A, rough turn profile, as shown in Fig. 2 forming a broad categorizing style body, broad categorizing style body body surface retains 1mm to 2.2mm thickness
Post-production needs the surplus removed；
B, by the overall Carburization Treatment of step a resulting parts；Part is placed in carburizing medium (gas or liquid), is heated to
900-950 DEG C, insulation makes part top layer 1.6-2.0mm increase carbon content to being more than 0.45%, forms carburized layer thickness for 1.6-
2.0mm；
The rough turn profile of c, twice, as shown in figure 3, forming a rough type body, retains carrying end face carburized layer without car
Processing, car falls remaining position carburized layer, the step 5 to convex, formation process lug is formed in interior end car system；Rough turn position
Body surface retains the surplus that the thick later stage finishing processings of 1.5mm to 1.8mm need to remove；
D, step c resulting parts are heat-treated, carburizing position quenching hardening and overall Ageing Treatment；It will complete
The part of Carburization Treatment, which is placed in heating furnace, to be heated, when Part temperature rises to the temperature that part material is undergone phase transition
After above, stop continuing to heat up, and keep at such a temperature after certain time, quickly cooling, by this quenching hardening process,
So that part carburized layer hardness reaches HRC55-62.Then artificial aging processing is carried out to the part after quenching again；Heat, protect
Temperature, cooling, reach the purpose for eliminating internal stress and stable processing dimension below.
