20.500.12556/RUL-145151 Effects of single/compound pit texture on the friction-induced vibration and noise of thrust cylindrical roller bearings Vpliv enostavne/sestavljene jamičaste teksture na vibracije in hrup zaradi trenja pri valjčnih aksialnih ležajih To improve the reliability and service life of thrust cylindrical roller bearings (TCRBs), the effects of single/compound pit texture on tribological properties and on friction-induced vibration and noise were studied. Laser marking equipment was used to create compound pit texture on a shaft washer. A universal friction and wear test rig was used to measure the friction force, vibration acceleration, and noise signals of TCRBs. The differences between the single/composite pit-textured and non-textured surfaces were studied in terms of the friction, wear, and vibration noise properties. The results revealed that the friction force and wear loss of the single/composite pit-textured surface were markedly lower than those of the non-textured surface. Compared to non-textured surface bearings, the friction force and wear loss for textured surface bearings were reduced by 39.6 % and 59.6 %, respectively, when the diameter, depth, and area density of the pit were 300 μm, 10 μm, and 10 %, respectively. The single/composite pit-textured surface exhibited good potential for vibration absorption and noise suppression. It could effectively interfere with the self-excited vibration of the TCRBs friction pair system, thereby reducing the degree of vibration noise of the TCRBs. thrust cylindrical roller bearings single pit texture compound pit texture friction force wear friction-induced vibration noise valjčni aksialni ležaj enostavna teksturirana površina sestavljena teksturirana površina torna sila obraba vibracije hrup zaradi trenja true false true Angleški jezik Slovenski jezik Članek v reviji 2023-04-11 09:12:02 2023-04-11 09:12:07 2023-04-12 03:32:48 0000-00-00 00:00:00 2023 0 0 Str. 87-99 no. 3/4 Vol. 69 Mar./Apr. 2023 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 621.8 0039-2480 10.5545/sv-jme.2022.455 148326659 Wang_...-Effects_of_single-compound_pit_texture_on_the_friction-induced_vibration_and_noise_of_thrust_cylindrical_roller_bearings.pdf Wang_...-Effects_of_single-compound_pit_texture_on_the_friction-induced_vibration_and_noise_of_thrust_cylindrical_roller_bearings.pdf 1 82F6C4E4A206615B7903D2D6F11D9AA6 d22f986c96487aab5ce0a423b28c415a8983869b85accd4b0dc900606c9c6e32 599c9481-d838-11ed-a314-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=167822 https://www.sv-jme.eu/sl/article/effects-of-singlecompound-pit-texture-on-friction-induced-vibration-and-noise-of-thrust-cylindrical-roller-bearings/ 1 0939457d-d838-11ed-a314-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=167821 Fakulteta za strojništvo Strojniški vestnik 0 0 0
