“…It has been verified by testing 14 that steel rolling bearings, which contain at least one rolling element made of ceramic (Si 3 N 4 ) improve substantially their performance under poor lubrication and high contamination conditions, therefore the next line of defence after nitriding or carbonitriding for lubrication with oil-refrigerant mixtures should be this type of rolling bearings so-called as semi-hybrids. The working mechanism is similar to hybrid bearings, explained already in Brizmer et al 41 and Vieillard et al 43…”

The paper describes the latest technological solutions in rolling bearings (ball and roller) used in refrigerant compressors. First, the numerous tribological challenges faced by rolling contacts in a lubricant environment made of oil and refrigerant mixture are discussed. It is followed by a description of the even tougher conditions derived by the replacement of the more chemically stable pre-Montreal and pre-Kyoto Protocol refrigerants by the new generation of more environmental friendly refrigerants. In these conditions, rolling bearings are expected to suffer from surface distress and sometimes corrosion fatigue. Thus, attempts to model these conditions by using advanced tribological models are described. Finally, descriptions of different solutions in rolling bearings in refrigerant compressors facing challenges in lubrication and bearing life are described, all the way from traditional oil–refrigerant mixture lubrication up to the latest innovation related to oil-free lubrication, namely the pure refrigerant lubrication.

“…The contact simulation between ball and inner ring that only used a portion of a full geometry of ball bearing and this used less time to carry out the simulation but all the simulations were carried out by using elastic model. Most of the studies on contact analysis only used the elastic model and only a few studies by Massi et al 2014 [8], Tonnazi et al 2017 [17] and Viellard et al 2016 [18] used the elasto-plastic model to carry out a simulation at ball bearing. The aforementioned studies used elasto-plastic model for wear simulation but not contact simulation.…”

This study is an analytical evaluation of contact and wear on ball bearings using the finite element method. Ball bearings are used in various sectors, such as in the automobile, turbine and aircraft engine industries, to reduce rotational friction and support radial loads. Nevertheless, ball bearings often experience failure due to wear as a consequence of contact pressure. The contact between the ball bearing components will affect the surface of the balls, and the inner and outer rings. Therefore, the main objective of this study was to examine the stress distribution and elasto-plastic deformation in order to analyse the contact between the ball bearing components. Most of the existing contact and wear models for ball bearings only take into account the elastic model. However, an analytical evaluation of contact and wear using an elastic model, while ignoring plastic deformation, is inaccurate. In this study, a contact analysis was performed using elasto-plastic models of a ball bearing, and the results were validated using data from a previous research. Boundary loads of between 100 N to 800 N were applied and plasticity values of 550 MPa, 1050 MPa, 1550 MPa and 2050 MPa were used to analyse the contact behaviour. As the boundary load increased, the maximum contact pressure and displacement of the ball bearing increased. As the plasticity, E2 rose higher, the maximum plastic strain was lowered proportionally.

“…However, the surface initiated fatigue can also be applied to pre-existing material defects and imperfections, which may occur in silicon nitride (Si 3 N 4 ) ceramic components of hybrid bearings. In many applications, these bearings overperform full-steel bearings (see [1,2]), and therefore the research in the field of hybrid bearings and Si 3 N 4 is of high interest.…”

Ceramic rolling elements of hybrid bearings may initially include surface imperfections. In order to provide reliable operation of a bearing, the criticality of such imperfections under rolling contact fatigue is examined by defining them as Star features: intersecting semi-elliptical surface cracks. Parametric study is conducted using Finite Element Method and discussed with help of previously published experimental observations. The effects of the Star feature morphology and configuration, contact pressure and crack face friction are investigated in terms of stress intensity factors. Possible crack propagation scenarios are explained in the present study.
