The subject of this diploma thesis is the design solution of the axial headstock, its gear box and main drive. This headstock is used for heavy duty gantry type machines from the production of TOS Kurim company. The thesis contains technical solution of the headstock, an analysis of the construction of the headstock drive, overview of the possible propulsion units, choice of the best drive variant, control calculations, technical proposal of drive design and economical evaluation of the whole reconstruction.

This master's thesis covers the construction analysis of an escalator by the Otis a.s. company and the conception of its modernization called "In-truss".This type of modernization consists in preserving the supporting construction of the 506-type escalator into which the components of newer 506-NCE series are to be built in. Such operation requires modifying the construction and creating adaptors used to anchor the new components to it. These modifications lead to the stress testing of the construction, that is done by using the finite elements method in NX-Ideas software. The thesis contains the design of selected subsystems of the escalator, the stress testing of the new supporting construction and the creation of volume model in CREO-Parametric application for further use.

В данной работе изучено общее строение станов ХПТ и в частности строение приводного механизма. На основе этих данных созданы модели деталей привода в системе трехмерного моделирования КОМПАС-3D. В программе Mathcad рассчитаны данные переходных процессов пуска двигателя, а в программе для моделирования систем Simulink смоделирован двигатель. Далее в среде для имитационного моделирования многозвенных трёхмерных механических систем Simscape Multibody собрана блок-схема приводного механизма рабочей клети стана ХПТ, к ней подключён электродвигатель. В результате исследования была получена имитационная модель приводного механизма рабочей клети стана ХПТ-90, проведена симуляция и исследование её работы. Данная модель позволяет: наглядно продемонстрировать работу механизма; обнаружить ошибки в работе; определить оптимальные параметры прокатки; оптимизировать процессы; снизить стоимость испытаний механизма; снизить затраты времени при проектировании. / In this work, the general structure of cold pipe rolling mills and, in particular, the structure of the drive mechanism were studied. Based on these data, models of drive parts were created in the KOMPAS-3D three-dimensional modeling system. The motor starting transient data was calculated using Mathcad, and the motor was simulated using the systems modeling software Simulink. Next, in the simulation environment for multi-link three-dimensional mechanical systems Simscape Multibody, a block diagram of the drive mechanism of the working stand of a cold pipe rolling mill was assembled, and an electric motor was connected to it. As a result of the study, a simulation model of the drive mechanism of the working stand of the cold pipe rolling mill (ХПТ-90) was obtained, a simulation and study of its operation was carried out. This model allows you to: clearly demonstrate the operation of the mechanism; detect errors in operation; determine optimal rolling parameters; optimize processes; reduce the cost of testing the mechanism; reduce time spent on design.
