One of the most important technological characteristics of the rubbing surfaces of the shut-off part of the pipe fittings (PF) of the transport pipeline systems (TPS) is their waviness, which is characterized by the deviation of the step of the wave to the height of the micro-roughness. The nature of the waviness is associated with oscillations of the working bodies of the executive devices of the technological equipment in the production process of manufacturing or repairing precision pairs of PF. The waviness of the rubbing surfaces of the PF shut-off part, as well as the high accuracy of their processing, is achieved by increasing the kinematic stiffness of the process equipment, as well as improving the methods and means for the precise processing of the PF precision pairs.

The main working body of technological equipment of screw rotor technological systems are screw rotors which present spatial objects with an original geometrical shape of working body perimeter in which component parts and granules of the processing environment carry out simultaneously continuous rotation around the axis of working body and progressive motion, constantly moving along a horizontal axis of working body rotation. This article gives a classification of perimeter forms of working bodies, such as screw rotors, which let to expand technological possibilities of technological equipment and to provide the increase of effectiveness of the production process by means of increase of its amplitude-frequency characteristics. The peculiarity of working bodies in the form of screw rotors is the fact that internal cavity of a rotor has a wavy shape, formed by the sides of a semicircular form. The paper covers on a construction and the principle of operation of machine-tools on the basis of working bodies in the form of screw rotors with a shaped surface on perimeter. The suggested design solutions of processing equipment allow creating highly effective machine-tools for the finishing and strengthening processing.

Ensuring the competitiveness of enterprises of the forest complex is largely due to the level of reliable and high-performance equipment use, since this achieves a significant increase in the efficiency of timber harvesting and processing. At the same time, the required level of reliability of logging machines is largely determined by the performance of their functional units that carry out the basic technological operations. Accordingly, the development and implementation of ways and methods to improve the performance of functional units of machines is important when creating promising models of the specified equipment. This requires an analysis of the prospects and technical possibilities for improving the main mechanisms and units of logging machines and the factors limiting their performance. In order to improve the performance of machine functional units, it is essential to ensure the coordinated provision of favorable levels of a significant number of design and technological parameters. In particular, it is advisable to optimize the nature of the relative movement of the friction-contacting surfaces of the parts and reduce the loads acting on them. This is due to the fact that these factors determine the wear resistance and friction resistance, as well as the thermal mode of the machine operation, the stress state of the functional surface layers and the strength of the fixed joints. At the same time, the influence of operating conditions, the wear intensity and service life of the objects under study should be taken into account. This approach is due to the fact that tribotechnical units of logging machines perform their functions under the action of high shock, cyclic and vibration loads, in a wide range of harsh natural and climatic conditions characterized by low temperatures, high humidity, and the action of chemical and abrasive media. All this should be considered when justifying effective ways to improve the performance of functional units, including manipulators of logging machines, and achieved through regulated directional control of the properties of surface layers in the design and manufacture of friction-contacting parts. The paper substantiates the need to create scientific and engineering foundations for improving the performance of functional units and working bodies of machines, as well as achieving the required performance, durability and reliability. For this purpose, the tasks of further research aimed at obtaining information, the absence of which makes it impossible to create domestic import-substituting equipment, are clarified.

Subject. The article discusses the availability of technological equipment in the agriculture of the Republic of Dagestan. Objectives. We analyze the current situation and trends in the development of available technological equipment in the republican agriculture, identify the role and place of machine and tractor fleet in the retrofitting of the regional agriculture. Methods. The study is based on monographic, abstract logic, statistical, analytical methods. Results. Dagestan has got a critically few technological equipment, which affects the development of the regional agricultural sector. The availability of technological equipment is found to have dramatically reduced in animal husbandry for the recent 30 years. The availability of technological equipment and land cultivation strongly correlates, thus simplifying applicable agricultural technologies. Most agricultural producers of Dagestan were found to be unable to participate in the program for federal agricultural lease. Conclusions and Relevance. The deterioration of available technological equipment in agriculture is a key cause undermining the competitiveness of products and efficiency of the regional agriculture. We prove the importance of governmental actions incentivizing the influx of new technological equipment, including a set of measures reinforcing the availability of technological equipment. As long as most agricultural producers are microbusinesses that lack resources to participate in many machine renovation programs, funding should be increased substantially to subsidize a portion of equipment acquisition costs incurred by agricultural producers, and a portion of reimbursed costs as much as at least 50 percent of the value of agricultural machines acquired.
