A Parametric Study on PM Gear Rolling Densification Simulations Coupled with Experimental Results
PM gear rolling densification is a post-sintering process in which the porosity is closed at the surface and at some depth into the flank of the gear.It results in improved mechanical properties such as higher contact strength,but can also be used to improve tolerances.The optimization of the rolling process,the design of the tool geometry,the gear preform and the overall process is time consuming.Therefore,FE simulations are used to optimize the overall process and reduce the development time.In previous research the simulations were shown to correlate well with experimental results both in terms of gear profile and densification.That investigation focused on gears of one density and rolled with one set of process parameters.In this article a sensitivity analysis will be presented.The same type of gear will be rolled with different parameters,and experimental gear and densification profiles will be compared with simulated results.The experimental accuracy and limitations of the simulations will then be critically examined.
