The main factors influencing the heating of the elastic elements of the couplings are damping of the coupling, ie the ability to extinguish harmful vibrations, the ratio of moments of inertia in the drive and operating arms of the transmission, the volume of the cooling area of the elastic element and the heat dissipation coefficient. Conditional limits have been set for the selection of elastic couplings, depending on the possible heating during operation. [ABSTRACT FROM AUTHOR]

Free-moving roller mechanisms are widely used in the propulsion systems of modern equipment. The surrounding rings of such mechanisms are affected by a normal strong load, which leads to significant radial deformation.They usually do not calculate the radial deformation of the surrounding ring, and give the geometric parameters in accordance with the design recommendations. There is no theoretical or experimental study of the stiffness of the surrounding ring. The results of the test of the effect of transmitted pressure (torque) and design parameters of the freemoving roller mechanism (instantaneous stopping angle and number of stopping rollers) on the radial deformation of the ring are shown. The accuracy of the proposed empirical dependence for the calculation of the radial deformation of the surrounding ring has been confirmed experimentally. For the vast majority of tests, the difference between the experimental and theoretical values of radial deformation was 2.9...17.5%.Experiments have shown that the increase in radial deformation with increasing pressure is slightly delayed and varies with degree of dependence; Increasing the instantaneous stopping angle from 5o to 9o leads to a reduction of radial deformation by 1.28- 1.51 times, while reducing the number of rollers from 3 to 5 reduces it by 1.5- 1.7 times.

The purpose of this paper is to design the process of quality management at the engineering enterprises of Azerbaijan. On the basis of previous works, authors propose the procedure for definition of management processes by production quality according to ISO 9001--2001. Also the article describes the ways of establishment of integrated systems of quality management with business orientation. It is concluded that in search of optimal solutions in the quality management system, in the evaluation of stakeholders' satisfaction with engineering production quality, the theory of inaccurate sets can be applied. Further research may be appointed in order to develop methods for modeling and optimization in the process of manufacturing engineering products, as well as the use of software systems. This paper provides new evidence about a still unexplored topic, trying to bridge the existing gap in the literature about the quality management system and its implementation at the Azerbaijan enterprises.
