20.500.12556/RUL-139632 Vpliv laserske gravure in deformacij prirobnice na variacijo amplitude gostote magnetnega polja vzdolž oboda magnetnega obroča The influence of laser engraving and flange deformation on the amplitude variation of the magnetic field density along the circumference of the magnetic ring V diplomski nalogi smo obravnavali pojav variacije amplitude gostote magnetnega polja vzdolž oboda magnetnega obroča. Do te je prišlo zaradi prisotnosti reže med obročem in magnetilnim nastavkom, ki nastane zaradi deformacij prirobnice obroča in laserske gravure. Na vzorcih, ki so izkazovali le enega od identificiranih vzrokov, smo z merjenjem aksialnega opletanja obročev dokazali njun vpliv na variacijo amplitude. Postavili smo hipotezo, da zaradi napake v izdelavi orodja med vulkanizacijo pride do deformacij prirobnic. Na vzorcih, izdelanih v novem orodju in označenih s prilagojeno gravuro, smo potrdili uspešnost rešitve problema. In this diploma thesis we discuss the phenomenon of the amplitude variation of the magnetic field density along the circumference of the magnetic ring. This occurred due to the presence of a gap between the ring and the magnetization attachment, which is caused by deformations of the ring flange and laser engraving. We demonstrated the influence of laser engraving and flange deformations on appearance of the amplitude variation, by measuring the axial runout of test samples that exhibited only one of the two identified causes. We hypothesized that due to a tool manufacturing error, flange deformations occur during the vulcanization. We confirmed the success of solving the problem on the samples produced in new vulcanization tool, marked with adjusted engraving. magnetni dajalniki variacija amplitude magnetenje laserska gravura deformacije aksialno opletanje vulkanizacija magnetic encoders amplitude variation magnetization laser engraving deformations axial runout vulcanization true false false [J.
