Путем аппроксимации графиков хода толкателя по поверхности эксцентрика предложена расчетная формула, которая с достаточной для практики точностью определяет ход толкателя в зависимости от угла поворота вала с эксцентриком. Предложены формулы для определения скорости и ускорения толкателя эксцентрикового механизма. Относительная погрешность при определении хода толкателя графическим и расчетным способами не превышает 6 %. С применением программы Mathcad выполнен расчет и построены графики пути, скорости, ускорения толкателя эксцентрикового механизма с эксцентриситетом 4, 5 и 6 мм при частоте вращения вала 1000 мин–1. Рассмотрено практическое применение эксцентриковых механизмов для систем питания двигателей внутреннего сгорания.</p></abstract><trans-abstract xml:lang="en"><p>The article determines the value of the pusher stroke of the eccentric mechanism with the 4 to 6 mm eccentricity basing on graphic research. By approximating the graphs of the pusher stroke on the eccentric surface, the authors propose a calculation formula, which defines the pusher stroke as a function of the angle of the eccentric shaft rotation for practical purposes. Moreover, formulae for determining the velocity and acceleration of the eccentric mechanism pusher are offered. The relative error does not exceed 6 % in determining the pusher stroke by graphical and calculation methods. Calculations and graphs of path, velocity, acceleration of the eccentric mechanism pusher with eccentricity of 4, 5 and 6 mm at a shaft speed of 1000 min-1 are calculated and plotted using Mathcad software. The practical implementation of eccentric mechanisms for power supply systems of internal combustion engines is considered.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>эксцентрик</kwd><kwd>эксцентриситет</kwd><kwd>программа Mathcad</kwd><kwd>ход толкателя</kwd><kwd>скорость толкателя</kwd><kwd>ускорение толкателя</kwd><kwd>применение эксцентриковых механизмов</kwd></kwd-group><kwd-group xml:lang="en"><kwd>eccentric</kwd><kwd>eccentricity</kwd><kwd>Mathcad</kwd><kwd>pusher stroke</kwd><kwd>pusher velocity</kwd><kwd>pusher acceleration</kwd><kwd>implementation of eccentric mechanisms</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Simionescu P., Talpasanu I.
