“…According to the curves in Figure 5, it can be seen that the friction torque of the test bearing under ordinary pressure ranges from 0.01 to 0.06 N•m, and the friction torque is relatively small because this paper aims at nonloaded aerospace (Wrzochal et al, 2022), the experimental data in this paper have certain accuracy.…”

Purpose The purpose of this paper is to test and analyze the friction torque of double-row angular contact ball bearings under vacuum or ordinary pressure environment, horizontal or upright installation mode, and different rotational speeds, and to provide theoretical bases for the development of aerospace equipment. Design/methodology/approach The experiments were carried out to investigate the effects of vacuum or ordinary pressure environment, horizontal or upright installation mode and different rotational speeds on bearing friction torque. To explore the relationship between working conditions and bearing friction torque, firstly, based on the generation source of friction torque, the test principle was determined, a test system was developed and the reliability of data was verified. Secondly, the friction torque of bearing was tested, and the values under various working conditions were obtained. Finally, this paper compared and discussed the test results. Findings The test results show that the friction torque value of vacuum environment horizontal installation condition is the largest at different rotational speeds, and the rotational speed has the most significant influence on the friction torque. Originality/value The friction torque test system of double-row angular contact ball bearing under vacuum environment was designed and built. The influence rules of vacuum or ordinary pressure environment, horizontal or upright installation mode and different rotational speeds on bearing friction torque were obtained.

“…Jak pokazuje praktyka przemysłowa, występuje konieczność wytwarzania łożysk tocznych o wysokich wymaganiach odnośnie do dokładności obrotu, minimalizacji generowanych drgań i szumów, z zachowaniem odpowiednich luzów współpracujących elementów [5,6]. Wymagania te można spełnić poprzez wytwarzanie części łożyska -pierścienia zewnętrznego i wewnętrznego oraz elementów tocznych -spełniających rygorystyczne wymagania specyfikacji oraz zapewnienie prawidłowego montażu łożysk w zespole.…”

In the paper a practical examples of objects from everyday life were presented with different meanings of form deviations for their functioning, such as: roundness deviation, cylindricity deviation, and the surface texture. For some of them, form deviations and the state of the surface texture are only of aesthetic importance, for others they determine their proper and reliable functioning. KEYWORDS: surface metrology, form deviation, surface texture Fig. 18.

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.
