Converter for mechanical stepless transmissions of automobiles and tractors
摘要
The device that transforms the rotation of a drive shaft of mechanical stepless transmission into angular oscillations of intermediate parts is considered. The rotation of fixed direction is transmitted from these parts to the driven torsion shafts by means of mechanical rectifiers (one-way clutch). The value of the device structural parameter, at which maximum loads acting on its units are considerably decreased, is defined.

Simulation of articulated transport-and-technological systems
摘要
The article is devoted to the problem of multisections articulated transport-and-technological systems modeling. Classification and analysis of options for the use of articulated transport-and-technological systems in various fields of national economy are given. A modular approach, which allows to use the object-oriented method for modeling and programming in the design phase, is suggested. This approach can considerably simplify and accelerate the creation of complex transport-and-technological systems.

Overload level by the act of adaptive friction clutches
摘要
Показано изменение внутренних силовых факторов, действующих в адаптивных фрикционных муфтах первого поколения с дифференцированными парами трения перед срабатыванием и в процессе срабатывания. Установлено, что теоретический вращающий момент муфт при срабатывании превышает его настроечную величину даже при больших коэффициентах усиления обратной связи, а распорная сила отжимного устройства имеет максимум внутри интервала изменения коэффициента трения.

About evaluation of constructive reliability of cylindrical springs with variable section by complicate deformations
摘要
In this work compression springs with torsion are examined. In calculations relations between kinematic and static characteristics, according to the Kirchhoff and Clebsch theory, are used. Calculation of springs on carrying capacity or reliability loss with critical values of torque and axial force determination is brought.
