Det är en smidd vevaxel (från nytt ämne), finfina grejer för den som vill ha det bästa :)
Köps hos Kent Karlsson, Sweden Motordesign
Står lite på Flaxis länk:
material
Arrow spec Corus 722M24.
Cleanliness is a major advantage, oxides are reduced by best steel making practice and controlling sulphur reduces sulphides. The resulting increased cleanliness / reduced impurities give a major improvement in transverse properties e.g. strength and ductility making the crank less likely to fracture. Improving the mechanical properties raises the resistance to shock and offers a better diffusion of nitriding resulting in increased endurance.
oil feed
The supply to the big end is optimized to maintain maximum oil film thickness and strength.
Low pressure from the main journals gives more efficient supply at higher RPM, it also enables the crankshaft to run at lower oil pressure reliably.
attention to detail
The fillet radii is critical. Radii must be full and of correct form in both rough and finished state, to ensure the nitrided layer is of uniform thickness around entire surface.
crack detection
100% inspection.
balanced
Between 2 and 15 grams (depending on number of cylinders).
inspection
100% critical detail check.
