Control of mechanical stepless transmission

Blagonravov A.A., Revnyakov Y.N.

Abstract

The principle of additional regulation of the multithread mechanical stepless transmission of impulse type is considered due to change of size of radius of a crank depending on external loading at work together with the diesel engine equipped with centrifugal governor. The circuit of system of automatic control of the transmission is offered providing work of the engine under the characteristic of the minimal charge of fuel at incomplete use of capacity in a wide range of revolutions of crankshaft.

Some statistic indices of functioning of sowing unit with elastic-damping mechanism in tractor transmission

Kravchenko V.A., Senkevich A.A., Senkevich S.E.

Abstract

The experimental research results obtained by operating the sowing machine-and-tractor unit equipped with elastic-damping mechanism which changes transmission properties, makes it compliant and, therefore, absorbing vibrations of the external disturbing influences, are dealt with in this article. Several performances of a unit with more rigid transmission are given as a comparison. The given correlation functions and spectral densities of the process show an evident improvement of operating characteristics.

Calculation of the average total operating time for the group of technical equipment with spare components

Korolkova L.I., Ignatyev G.S.

Abstract

The functioning of the group of technical equipment is examined, the duration of its no-failure operation is determined by one of its components, and long-term performance is ensured by replacing the failed component by the spare one. Relations are obtained for calculating the average total operating time of the group of technical equipment with spare components by their work during the random allotted time, with and without taking into account the time of replacing the failed component.

Kuznetsov Y.N., Al-Dabas K., Manilo I.I.

Abstract

The eccentric tool tightening chuck with two cinematic circuits «wedge-eccentric cam» and an intensifying link was offered. Two stages of work of the eccentric boring-and-milling chuck (EBMC), which provide the creation of necessary force for tool clamping, were shown. Adduced were the calculation and function-structural diagrams and conditions for definition of reinforcement coefficients of EBMC due two cinematic circuits in order to receive the necessary radial tool clamping force from one eccentric.
