aluminum steering box

[Colaexperienced]

Bye to all,

I am a student of aeronautical engineering and I am designing a steering box for a racing car.

since the forces at stake are relatively small (the axial forces in the steering arms reach up to 1000 n), I thought of making the teeth of the pinion and the rack in alloy
of aluminium 7075 t6 (sy=505 mpa hb=160).

for bending resistance there are no problems.

with regard to wear resistance (which is probably the most restrictive requirement for aluminium) instead I found no usable data.
I would therefore need data relating to aluminum alloys to be able to measure with sufficient accuracy the teeth of the surface fatigue steering.

Thank you.

aluminum is not the maximum for gears you can qmq expect to make hard anodization remembering that it goes to deposit for some 0.01 on the surface, you have to communicate it to those who anodes you how thick it must be, so you have to take into account in the project phase

Good poet!
You're a colleague then! speak the circling with articles of surface treatments.
I have a pvd plant 100 mt from my desk, but for the gears I continue to prefer diffusion treatments.http://www.aimnet.it/allpdf/pdf_pubbli/mar10/brunelli.pdfcolaexperienced, what data do you need? I think you can find this link useful: http://www.tribology-abc.com/sub15.htm, there is the specific section for aluminium alloys and computing tools (1 for surface fatigue from pitting (iso 6336-2)).

Thank you for your help.

I think anodic oxidation lasts more than enough (maybe even excessive). Does anyone of you know how much it can cost?

I still have uncertainties about how a wearable aluminium wheel can be sized: on the textbook that I use (juvinall) there are not sufficient data (evidently because a toothed wheel in aluminum alloy is not frequent). However, superficial hardness that can be achieved by anodic oxidation (between 300 and 500 hv) should be more than sufficient.
