The article presents the results of the analysis of existing designs of non-coaxial planetary gearboxes, their advantages and disadvantages. The invention is related to transport machinery area, transmission of transport vehicles, land transport systems, including motor vehicles, tractor-trailers, construction and road machines, tractors and ground-based equipment for special purposes. The design and kinematic scheme of a non-coaxial multiple-speed shaft-planetary gearbox, type 24R10, are presented. The work describes the operation of a non-coaxial multiple-speed shaft-planetary gearbox, type 24R10 (24 direct gears and 10 reverse gears), as well as gear ratios for each gear. A technical and economic assessment of the non-coaxial multiple-speed shaft-planetary gearbox, such as 24R10, is given. It is shown that the task is solved by compacting the layout of the multiple-speed gearbox and the planetary mechanism both in gear and summing modes, as the torque enters two links and is removed from the third one. The research proves that the design of a non-coaxial multiple-speed shaft-planetary gearbox, type 24R10, provides an improvement in the layout and operational characteristics of the gearbox and, accordingly, the operational capabilities of the vehicle.
The relevance of the problem under consideration is caused by the existing discrepancy between the increased need of society and the state for high quality engineering education, and the actual level of readiness of graduates of engineering universities to perform their professional functions, as well as insufficient development of the theoretical foundations of students training in research in the context of competence-oriented education. The purpose of the article is to solve the problem of training students for the research activity in the course of independent work and research during the educational process at engineering university. Based on the systematization and development of existing approaches to solving the problem of training of students of engineering universities for research, which contributes to the development of a functional model, the authors propose the method of preparing students for research. The article describes the development of practical experience in research activities during the participation of students in scientific seminars; represents the process of using the project method, end-to-end research tasks when preparing the course and qualification works; the issue is considered on consolidating and improving the experience of research activities of future engineers during all kinds of practical training. The pedagogical experiment was aimed at identifying the effectiveness of independent and research work in the course of formation of students' readiness for research activities in the framework of the functional model. The materials of the article can be used by the academic staff of engineering universities, specialists in the field of pedagogy, theory, and methodology of vocational education, as well as in the system of extended education
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
