Synthesis of Vibration Gear Continuously Variable Transfer

Abstract

Drives of machines which are used now do not possess ability to be adapted for extreme working conditions. Such conditions are connected with possible difficulties of motion because of deviations from operation norms (for example, because of long inactivity, deterioration of conditions of lubricant, minor damages, a temperature difference, etc.). In the conditions of impossibility of elimination of minor failures on the move (for example in aeronautical engineering) insignificant discrepancy of operation of service mechanism can serve as a cause of accident. Recently the technological direction of use of adaptive drive of machines is advanced. The adaptive drive mechanism engages the engine and the self-regulated transmission mechanism. The adaptive gear transmission mechanism with two degrees of freedom has ability to actuate an executive working body with a speed back—proportional external load at constant engine power. It means that even in presence of handicap in motion of working body the drive mechanism breakage will not occur. The adaptive vibrating mechanism in the form of the closed gear differential is developed. The vibrating mechanism contains input carrier, output carrier and closed contour located between carriers. The closed contour contains input satellite, external block with two ring (epicycle) wheels, output satellite and internal block with two solar wheels. The wheels in each block are connected by elastic shaft. In an operating time elastic shafts transfer vibrating oscillations to the output carrier. Output carrier transfers vibrating action to working body. The vibrating mechanism provides reliable overcoming of operational overloads. In offered work synthesis of the vibrating mechanism on the set vibrating action is executed. Work is executed on the basis of mechanics laws.
