“…Thus, a method of creating a three-dimensional model of gear transmissions in the relevant integrated CAD [15,16] should be included in the designer's toolkit. The integrated CAD system KOMPAS-3D [17,18] with application libraries and APM Graph module for parametric modeling of shafts and mechanical gears is promising in this regard.…”

In this paper, the mechanism of a slotting spindle head for the implementation of rectilinear motion based on a rack and pinion is considered. A three-dimensional modeling procedure of the slotting head elements for a multioperational machine tool of the drilling-milling-boring type has been carried out. 3D models of the rack and pinion were built in the integrated CAD KOMPAS using its built-in geometric core. An assessment of the stress-strain state in the engagement zone is given using the finite element method. The concept of increasing the load capacity due to the proposed version of the teeth envelope surface with curved axoids is analyzed. An analytical apparatus for determining the basic design parameters of a rack and pinion transmission modified version is proposed. The calculation of the geometric parameters for the end profile of the gearing teeth is experimentally realized, taking into account the found value of the disk milling cutter diameter for teeth cutting by the copying method.

The monograph deals with the design, calculation and modelling of gear cutting tools. Calculation forms are proposed for the creation of tools structures working by the methods of form-generating and form-copying. Three-dimensional and parametric models of worm wheel hob and worm spline cutters, shaper-type cutters and interlocking disk milling cutters in the environment of integrated CAD KOMPAS-3D and APM WinMachine using specialized applications "CAD Mills" have been built. Calculation forms for determining the geometric, kinematic and design parameters of worm wheel hob for the manufacture of spur and helical gears based on the original contour profile of a standardized gear rack are given. An interactive design of a worm wheel hob in the KOMPAS system was carried out. The design stage of determining the characteristics of the flank-shaped tooth profile modification to reduce the noise level and increase the service life of the gear transmission has been effectively implemented. An interactive procedure for designing a worm spline cutter in the KOMPAS environment for finishing spline shafts is proposed. At the stage of replacing the theoretical profile of the cutter tooth edge with an arc of one circle or tangent arcs of two circles, an express procedure for calculating the magnitude of the error is used. Computer design and research of the shaper-type cutter using the application program "Shaper cutter" in the KOMPAS-3D environment was performed. It is shown that for non-standard shaper-type cutters it is possible to use a standard helical copier of a gear shaping machine if the angle of teeth inclination is 15 0 ±0.5 0 or 23 0 ±0.5 0 . A comprehensive study of interlocking disk milling cutters using the application program "Disk milling cutter" in the CAD KOMPAS contour was carried out. Parametric models of the disc cutter design are built using the syntax of the CAD APM WinMachine. The parametric models of a single-and double-relief tooth, as well as the involute profile of the tooth lateral surface, have been identified.

“…The creation of fundamentally new machines and equipment, improvement of existing ones using resource and energy-saving technologies are topical scientific and technical tasks [1]- [4]. The most complete requirements for resource savings are met by machines and process equipment with a hydraulic drive [5], which due to its known advantages has been widely used in various branches of mechanical engineering as actuating mechanisms of modern mechatronic modules [6], production process control systems technological and mobile machinery [7]- [9]. At the same time, the level of use of hydraulic drives and devices in machines is an indirect indicator of their technical level.…”

To date, the assessment of the technical level of individual elements of hydraulic drive systems has been significantly addressed, but most of them were positive-displacement machines. Thus, the development of a criterion which takes into account the maximum number of indicators and hydraulic devices and is based on common methodological principles is an important scientific and technical task for the assessment of the technical level of hydraulic machines, hydraulic units, and hydraulic devices. Based on a systematic analysis of the technical level evaluation indicators of a wide range of hydraulic drive system elements, namely hydraulic machines, hydraulic units, and hydraulic devices, a definitive criterion for assessing their technical level is synthesized. There were two stages in the study: theoretical and experimental. Initially, the most important factors influencing the reliability and efficiency of hydraulic devices were defined on the basis of operations research methods (hierarchy analysis method and multicriteria optimization). After the synthesis of the criterion, an experimental test was carried out based on a comparison of maintenance costs of real hydraulic devices. The obtained criterion allows one to make an assessment depending on constructive and operational indicators, based on common methodological principles. A comparison of the characteristics of maintenance costs of hydraulic devices per unit of power was made. Characteristic curves are hyperbolic, which proves the validity of the criterion.
