Introduction. Therefore, elucidating of the wear in the rolling considering slip is an important task for improving the durability of tribotechnical characteristics of contacting surfaces, such as a friction pair «cable block – rope».
Research methodology. Tests are conducted in accordance with DIN 50324, ASTM G99 «Standard Test Method for wear Testing with a Pin-on-Disk Apparatus», as well as standards ASTM G 133, ASTM D 3702, ASTM D 5183, ASTM D 4172 and ASTM D 2266.
The tests of the samples being rolled with the slip were conducted on a wear machine MI the top shaft of which was able to rotate, and was returned about a vertical axis at an angle of 5°, which provided lateral slip about 10% of that observed in the friction pair «cable block – rope». To measure the wear weight loss of samples used VLR – 200.
The results. Found that wear actually depends on the load, but depends only on the slip.
In the case of rolling with longitudinal slip, equal to 10% of the friction surface become brown color, typical of oxidative deterioration. When cross-slip surface layer due to lateral plastic flow continuously updated. In longitudinal slip surface areas and products of wear, moving along the circle skating, interact repeatedly, increasing the role of corrosion during wear. Speed oxidative deterioration was dependent on the hardness of steel, so the impact of hardness on the results of experiments with longitudinal slip offset that should be considered when analyzing the results of a wear machine MI.
Thus, one could argue that the slip to 10% speed deterioration is almost independent of pressure or even decreases with its increase.
When changing operating conditions tribosystem wear rate may change abruptly, thus changing the surface friction type, size, color and chemical composition of the products of friction, that is a result of the transition from one mechanism to the second wear.
Boundary layers of bodies or surface film, with their contact during the rolling of the sliding friction coefficient reduce to 3 – 4 times and thus the speed and intensity of wear. Therefore, by changing the coefficient of friction may establish a process erase surface films.
Conclusions. Surface roughness effect on friction coefficient of friction and wear rate when rolling with slip, i.e. with decreasing surface roughness decreases.
If the slip is up to 2% it is seen as a sharp change in friction can be observed, after which it remains practically unchanged through the distribution of slip on the entire area of contact.
Key words: pair of friction, slipping, rolling motion, crumpling, coefficient of friction, rolling-off by a roller.

Currently, it is increasing the use of electric machines of alternative designs and special designs in a variety of technical and technological facilities. Such machines are axial induction motors with a flat working gap, as well as single and double rotary complements. Using axial motors instead of machines with a cylindrical working gap enables improved fans, compressors, pumps and other mechanisms. One of features of electromagnetic systems axial electric machines is uneven distribution of the magnetic field in the working gap and the active volume due to change of geometrical parameters of the jags and the yokes in the radial direction. This feature requires consideration when selecting the geometric relationships of the magnetic elements and defining characteristics of the machine. The results of the development of a mathematical model of the distribution of induction of the magnetic field in the gap, the jags and the yokes of the stator and rotor along the active length of the asynchronous machine with squirrel-cage rotor and a coiled magnetic core. On the basis of the separation of the active volume elements Tarn coaxial layers and based on the constancy of the magnetic motive force in the winding direction of increasing radius, defined by a system of equations relating to geometric and electromagnetic parameters of axial electromagnetic system. For accounting the magnetic circuit nonlinearity approximation is made of the magnetic characteristics of electrical steel tooth zone and the yoke. On the basis of numerical solution of the developed system used to analyze the effect of magnetic loads and structural and geometric relation-magnetic elements decisions on the distribution of the magnetic field version four-pole motor 550 watts. It has been shown that the reduction in the material capacity of yoke and an electromagnetic motor system as a whole, reaching the combination of induction and increase the use of trapezoidal configurations of sections of the yokes. The developed calculation method allows possibility of considering the peculiarities of the distribution of the magnetic field at the optimizing parametric synthesis of axial induction motors.
Keywords: axial induction motor, induction in the working gap, magnetic-moving force, magnetic circuit.

The aim of the study was to conduct a comprehensive analysis of indexes of meaty of carcasses, meat and fat quality of pigs of different commercial genotypes for developing production optimization system of high quality pork.
Studies were conducted on fattening pigs of three high meat productive pig combinations. As a maternal basis of every combination it was used combined sows of breeds Yorkshire and Landrace (YhxL), which were artificially inseminated with sperm of boars of American selection (company «Clayton Agri-Marketing») – Yorkshire (Yh), Hampshire x Duroc (HhxD) and Berkshire x Duroc (BxD). Pigs of each genotype (10 heads) fattened to the live weight of 100 kg at full compound feeds using feed additives of «Prostafeed» company.
The evaluation of pigs’ carcasses was carried out after 24 hours of gradual cooling at + 2- + 4 ° C. It was determined the morphometric parameters and content of lean meat in the carcasses for an estimated level MF, which was calculated by “two measures” metod (Germany 2011) according to the European system (S) EUROP. Under conditions of the Laboratory of zootechnical analysis and meat quality of Institute of Pig Breeding and AIP NAAS it was analyzed samples of meat from. longisimus dorsi, m. semimembranosus and back fat of pigs.
It was found out that carcasses quality and output of lean meat correspond to higher classes of (S) EUROP system – S (60.8-62.5%) and E (55.0%). However, analysis of complex technological indexes of meat of pigs of breed combinations in most valuable parts of carcasses – m. longisimus dorsi, m. semimembranosus – electrical conductivity, heat loss during processing and water-holding capacity, shows signs of clearly marked PSE-pork. However, there are high losses of carcasses during cooling and storage. Signs of PSE-pork especially reflected in pigs in combination of sows Yorkshire x Landrace with boars Hampshire x Duroc.
The chemical composition of pigs’ meat of studied groups also correspond to the current level of lean pork: with high protein there is low fat content.
For indexes of low melting temperature and high moisture content, vertebral fat of commercial pigs correlated with obtained characteristics of meat quality, which is at the level of display of PSE-meat.
It was done the conclusion about the need of using a comprehensive system of optimization of indexes of meat productivity and meat quality of pigs of high meat commercial genotypes that reduces the loss of products.
Key words: pigs, comersial combination of breeds, quality of carcasses, meat quality, m. longisimus dorsi, semimembranosus muscle.
