Topografija drsnih površin za gredi

Prša, Aleš (author), Pušavec, Franci (mentor)

Vijačnica na tesnilni površini gredi je problematična, saj privede do izgub mazalnega sredstva v sistemu. V zaključni nalogi smo iskali postopek obdelave, pri katerem se ne ustvarja vijačnica. Pri vseh postopkih smo izvedli test z nitko in posneli površino s 3D-merilnim mikroskopom Alicona. Površino brez vijačnice po testu z nitko smo uspeli doseči le z obodnim stružilnim frezanjem.

Abstract

Lead on the sealing surface can be problematic as it can cause loss of lubricant in the system. In this paper, we are searching for the process that does not produce lead. We performed tests with the so-called thread method and scanned the surface using the 3D measuring microscope from Alicona. After performing the test using the thread method, we determined that the only process that did not produce lead was done using the circumferential turn-milling.
