AB  - Potrebno je odgovarajuće podmazivanje kotrljajućeg ležaja kako bi se smanjilo trenje između površina u međusobnom kontaktu i njihovo habanje. Mazivo bi trebalo da u potpunosti odvoji kotrljajuće elemente od staza. U radu su analizirane vrednosti koje utiču na efikasnost i režime podmazivanja, nakon čega se uvodi koeficijent režima podmazivanja. Ovaj koeficijent omogućava da se na jednostavan i brz način odabere optimalna kombinacija kotrljajućeg ležaja i maziva na osnovu poznate brzine osovine, spoljašnjeg opterećenja i radne temperature kotrljajućeg ležaja. Za pojedine ležajeve sa radijalnim kontaktom i određena maziva prikazana je zavisnost režima podmazivanja od brzine osovine i kontaktnog opterećenja.
AB  - Appropriate lubrication of the rolling bearing is needed to lower the friction between the surfaces in mutual contact and their wear. A lubricant should completely separate the rolling elements from the raceways. The values that affect the efficiency and regimes of lubrication are analyzed in the paper, after which it is introduced a lubrication regime coefficient. This coefficient makes it possible to choose in a simple and fast manner an optimum combination of rolling bearing and lubricant based on the known shaft speed, external load, and rolling bearing operating temperature. For certain bearings with radial contact and certain lubricants, the lubrication regime dependence on the shaft speed and contact load is shown.

AB  - Surface texturing is one of the surface modification techniques which deliberately change the texture of the surface, in order to improve, among other things, its tribological performance. This is obtained through different patterns, which can be on micro or nano scale, created on the contact surfaces. The performance of a textured surface depends on the shape, geometry and pattern of the surface texture and the operating condition of the components in contact. There is a number of various techniques for surface texturing, among which laser surface texturing is most often used. The different surface texture shapes, different textured area ratios and patterns, different lubrication regimes with different contact geometries and materials have been subject of theoretical and experimental research for many years. This paper reviews the state-of-the-art of researches that consider various surface texturing for tribological application, as well as its effect on performance enhancement. Conclusions of this paper may provide guidance for optimal design of surface textures in practical engineering applications.

AB  - Biomimetics, biomimicry and bionics are synonyms for the scientific discipline of creating new structures inspired by nature. Biomimetics systematically analyses the evolutionary processes of living organisms, their structural relationships, the characteristics of natural materials and it studies how this knowledge can be used to create the optimal products and new sustainable materials. In the past decade, the biomimetics has received an incentive for the development by the technology modernization, and above all, by making it possible to study the micro-and nanolevels of biological structures. On the other hand, the miniaturization of technological devices has increased the need to understand the tribological phenomena on micro-and nanolevel, where is a huge potential for technological innovation. The integration of advanced research methods made it possible to discover new aspects in the structure and properties of biological materials and transfer that knowledge into new concepts or products. State-of-the-art of biomimetics progress is discussed, as well as, its goals and the potential to simultaneously achieve the financial and ecological contribution by realization of bio-inspired concepts. An overview of biomimetic researches is also provided, with special emphasis on the possibility of their tribological applications. The characteristic examples have been presented and those examples show how the structural and mechanical properties of the material were used as the basis for developing new creative solutions to solve the problem of friction in engineering applications.

AB  - Taguchi method has been used to analyse the influence of the coefficient of the trochoid radius, the number of revolutions and the working pressure on the change in the flow rate and the volumetric efficiency of the trochoidal rotary pump with internal gearing. The coefficient of the trochoid radius, as a geometrical parameter and the number of revolutions and the pressure, as working parameters are considered influential factors in this paper. Taguchi robust design and orthogonal matrices have been applied to design the experiment and to determine the degree of the factors influence, as well as their optimum values. The highest values both for the flow rate and the volumetric efficiency have been obtained for the coefficient of the trochoid radius of 1.375, the number of revolutions of 2000 min(-1) and for the working pressure of 1 bar. The conformation of the experiment shows that Taguchi method can be successfully used for selection of the optimal combination of parameters so that the maximum volumetric efficiency of the trochoid pump can be achieved.

The joints were welded on S690QL high strength steel plates using the Metal Active Gas (MAG) Welding and two filler materials of different properties. Since the steel S690QL belongs to a group of steels with high strength, the aim of this paper is to determine the temperature at which strength starts to decrease. Experimental tensile testings of the welded joints were performed at five different temperatures in the range from 20 to 550 °C.

AB  - For the aims of mechanical parts and assemblies quality providing, it is necessary to meet the basic requirements of construction related to form, function, material and process development. Form of mechanical part resulted from the harmonization of those requirements and the task of designer is to identify the optimal construction form. This paper presents the analysis of effect of the geometric parameters variation on the stress level at joint yoke of Cardan shaft transmitter. The main function of the power transmitter with Cardan shaft is to transmit power and rotation between shafts with variable position, or certain angles, of the axis during exploitation. Joint yoke is one of the essential parts of the Cardan shaft. In most cases, the major influential factor to dimensions and reliability of Cardan shaft are the properties of its joint yoke. In the study presented in this paper, the stress limit at the joint yoke is calculated by analytical method, and then, obtained result is proven by numerical method. It is shown that small variations in geometry of the joint yoke lead to the significant reduction of stress level. Iterative procedure of the forms corrections and repeating of numerical calculations of stresses have been done to identify favourable relation between geometric parameters of the joint yoke.

AB  - A cross shaft is one of the most important parts of the Cardan joint. In most cases, the size and lifetime of the Cardan joint depend on the cross shaft. To ensure the quality of mechanical parts, it is necessary to fulfill the basic constructional requirements related to the form, function, material and manufacturing procedure. The form of mechanical parts is the result of adjusting all of these requirements, and the task of a constructor is to develop forms with the aim of finding the best solution. This paper describes the procedure of determining the effect of geometry changes on the stress level in the cross shaft of the Cardan joint. The task of the Cardan joint is mechanical transmission of power and motion between shafts that change the position of their axes in the process of exploitation or are placed at a certain angle. The critical stress at the cross shaft was calculated by the analytical method and tested by a numerical solution. It is shown how small changes in the geometry of the cross shaft can lead to a significant reduction of critical stress. The most favorable ratio between the geometry of the cross shaft and the extreme stress values has been obtained by the means of the iterative correction of the form and the repetition of the numerical stress calculation.

AB  - In this paper will be represented how changes in geometry can affect on size of the stress change cross shaft of cardan joint. The task of the cardan joint is mechanical transmission of power and motion between shafts which are changing position of the axis in the process of exploitation or are placed at certain angles. Cross shaft is one of the most important parts of the cardan joint. In most cases the lifetime of cardan joint depend from the cross shaft. The critical stress of cross shaft will be calculated using the analytical method and been tested by numerical method. To the numerical method used as reliable for further change the geometry cross shaft. We can see how small changes in geometry of cross shaft can lead to a significant reduction on critical stress. Increasing radius in the transition and basis sleeve of the cross shaft reduces the critical stress at the root up to 40%. It will be the comparisons of the results in order to come to the best of the geometric shape of a cross shaft which has the lowest critical stress.
