“…Despite the great interest of researchers in determining the relationship between inclusions and strength, in particular fatigue strength, it was not possible to clearly define this relationship. The presented knowledge is based on hypotheses [38][39][40][41][42][43][44][45]. It was confirmed that the fatigue strength of metal alloys depends not only on its microstructure, but also on the quantity and quality of non-metallic inclusions.…”

A modern user requires low operating costs, but also reliability from machines and technical devices. Reliability during the service life depends on the quality of construction solutions, but also largely on the quality, properties and adaptation to the working conditions used in the construction of construction materials. During the operation of technical objects, their a highly predictable wear occurs. The problem is the phenomena of premature wear and damage of elements. The causes of failure of technical facilities are usually complex and depend on many factors. They can include the human factor and the one related to the quality, selection, production and technological processes of the materials used in the construction of the facility. In real technical facilities, many premature failures are caused by material fatigue, which is related to the imperfection of the material and the morphology of non-metallic inclusions. The paper presents the change in fatigue strength for rotational bending of highpurity structural steel. In order to diversify the matrix of inclusions, the steel was hardened and tempered at temperatures from 200C to 600C. The influence of impurity diameter and arithmetic average impurities space on the fatigue strength of industrially produced steel was investigated.

“…Modern machines operate at high speeds and workloads, frequent changes in operating modes and overloads [1][2][3]. In such conditions, the development of devices for changing the speed and protection against overloads, capable with high load capacity and stability of characteristics to provide effective protection against overload is an important problem for mechanical engineering science.…”

Article deals with safety-overrunning clutches for mechanical transmissions. Modern design of safetyoverrunning clutch with grooves sides inclined to semi-coupling radius has been described and researched in the article. It has practical value for creation modular-type machines. On the basis of the theoretic studies, the expressions for obtaining the main specific operation parameters have been proposed: rating torque, beginning and ending operation torques. As the result of the studies, the equations for estimation the clutch main operation characteristics have been received -rating torque exceeding coefficient, coefficients of clutch accuracy and sensitivity. On account of modeling and comparison with clutch where grooves sides are parallel to the radius made a number of important conclusions. The analysis performed demonstrates that clutches with inclined to radius grooves sides in general have higher operation characteristics compared with clutches with parallel to radius grooves sides, particularly higher accuracy coefficient and lower rating torque exceeding coefficient. Obtained results make it possible to recommend for highly loaded large-mass systems clutches with low values of grooves to clutch axe and grooves sides to radius inclination angles, because it provides balls contact with plane sides grooves surfaces and through this allows to decrease contact stresses compared with clutches with grooves sides parallel to radius; allows to provide high load capacity with low rating torque exceeding in overload mode; in clutches with inclined to radius grooves sides friction impact manifests less in operation with high rotation frequency.

The presented work is devoted to the improvement of spur gears of the reduction drive for metal-cutting machines according to the criterion of load capacity. A feature of this article is the creation of such a constructive solution, which is aimed at finding a compromise between reducing contact loads in the engagement zone and increasing the complexity and labour intensity of the manufacturing gears process. A procedure for accelerated creation of 3D models of a gear drive and its components using the specialized software application "Shafts and Mechanical Transmissions-3D" in the environment of integrated CAD system KOMPAS-3D is proposed. A study of a new cylindrical gear transmission design with a longitudinal generatrix of axoids, confirmed by the corresponding patent solution is realized. A calculation form for the practical design and manufacture of a new design cylindrical gear is proposed.
