Gear variator is a planetary train with constant gearing of toothed wheels and with the variable transfer ratio. Information on a gear variator occurs in the restricted number of patents and publications. The reliability of the gear variator calls a doubt as its kinematic chain has two degree of freedom at presence only one input. The additional constraint preserving a property of the two-mobile kinematic chain can provide reliability of motion. Such constraint is found. In the paper the existence of a gear variator with the brand new additional geometric constraint providing the variable transfer ratio is proved. © Springer International Publishing AG 2018.

This article describes the development phase of rotary sensors and current detection unit loading of the engine system with respect to the agreed rotation of asynchronous motors. The use of current sensors and the block allows you to create multi-engined loading of asynchronous electric-phase synchronous rotation with increased synchronization capability. © 2016 IEEE.

The paper presents expressions describing the time-of-flight of charged particles in the emission system, taking into account the time-of-flight chromatic aberrations up to the fifth-order of the infinitesimal. The spatial time-of-flight characteristics of the axially symmetric emission system consisting of two equal-sized coaxial cylinders and a plane cathode were obtained. As for the system under consideration the authors determined conditions compensating for the first-order time-of-flight chromatic aberration at the expense of the fifth-order aberrations. © 2010 Elsevier B.V.

The authors consider focusing of charged particles in the two-electrode electromagnetic mirror with rotational symmetry whose cylindrical electrodes also act as magnetic electrodes. Calculations for different ratios of magnetic and electric components of the electromagnetic field have been made. The region in variations of geometrical and electrical mirror parameters where the third-order aberration vanishes to zero has been detected. © 2010 Elsevier B.V. Allrights reserved.

A new principle is proposed for eliminating the energy spread of ions in a packet generated by the ion source of a time-of-flight (TOF) mass reflectron. The ion source is treated as an element of the optic tract, in which the ion trajectories are conjugated with those in the electrostatic mirror, while the primary temporal focus near the source is absent. By properly selecting parameters of the emission-reflection system comprising a combination of the ion source and electrostatic mirror, the total time of ion flight from the source to detector can be controlled so as to be independent of the ion energy. Numerical simulations have been used to find the optimum parameters of a three-electrode electrostatic mirror possessing rotational symmetry, which simultaneously ensure the TOF control (to within third-order terms) and the spatial focusing of ions in the detector plane. © 2014 Pleiades Publishing, Ltd.

Action of robot with modules which have adaptive electric drives is considered. Adaptive electric drive contains electric motor and adaptive connecting gear with two degrees of freedom. The adaptive gear has a form of closed differential mechanism and is extremely simple. It changes a transfer ratio depending on loading continuously only at the expense of mechanical properties and does not demand any control. The equations of adaptive mechanism parameters interconnection are worked out. Definability of the adaptive electric drive motion is confirmed by experimental research. Stop regime of the module motion takes place when working body of the module is motionless. This regime allows to avoid an overloading and to overcome emergencies. In the robot with adaptive drives of modules the stop regime of motion can be overcome at the expense of motions of other modules leading to decrease of resistance. © Springer International Publishing Switzerland 2014.

Paradox of the mechanism theory has been detected in connection with attempts of practical use mechanism with two degree of freedom and one entry for achievement of power adaptation. According to the mechanism theory and machines such mechanism is statically indefinable. However recently there were patents and publications with the description of efficient two mobile adaptive mechanisms with one entry. Paradox of the mechanism theory consists in the following: the kinematic chain with two degree of freedom and one entry containing the closed contour is statically and kinematically definable. In Ivanov’s works the proof of definability of two mobile kinematic chain motion is resulted on the basis of additional analytical constraint by a virtual works principle. A certain geometrical image comparable to design there should match to analytical additional constraint. The present work is devoted to disclosing of a geometric constraint of parameters of kinematic chain with two degree of freedom and to statement of the mechanism theory paradox in geometrical and an analytic form. Work is executed on the basis of regularities of mechanics and mechanism theory. © Springer International Publishing Switzerland 2014.

The expressions describing the time-of-flight (TOF) and conditions of TOF focusing of ion packets by energies in the ion source with two accelerating gaps have been obtained. The first gap is the ionization region with a uniform electrostatic field, whereas the second gap is the immersion objective with a non-uniform electrostatic field, where the role of the "cathode" (emitting surface) is played by the exit window of the ionization region. Numerical calculations were used to obtain the ratios between geometric and electrical parameters of three-electrode immersion objectives with two-dimensional and rotational symmetry, determining conditions of four orders of TOF focusing by energy simultaneously with spatial focusing of ion packets. The schemes of time-of-flight mass spectrometers of high resolution and high sensitivity with direct and orthogonal ion injection are presented. © 2014 Elsevier B.V. All rights reserved.

This paper briefly describes the design of a novel continuous variable transmission that can be used to adjust the transmission ratio according to the externally applied load. A detailed 3D CAD model has been proposed in order to investigate the engineering feasibility of the proposed design solution. Main design variables and constraints have been selected by referring to a practical application as a speed reducer on a small wind mill. A proper dynamic model has been developed within MSC ADAMS software. Simulation tests have been carried out and preliminary discussed to validate the proposed design solution. © Springer International Publishing Switzerland 2014.
