Perspective directions of mechanical power transmission research

A lot of publications are devoted to the study gear transmission, which cover all features their design, operation and repair. An in-depth analysis factors that were not taken into account a decade ago was carried out. The efficiency drive, taking air resistance, stress-strain state tooth, centrifugal deformations, determined. Thus, there constant complication tasks researchers set themselves. At same time, recent achievements in natural sciences have led narrowing field use gears. electric motor replaced internal combustion engine, an important object research for mechanical engineers. widespread DC motors with speed control has abandonment gearboxes vehicles metalworking machines. Application gears devices. starting ordinary watches, ending mechanisms computer disk drives, is thing past. Further studies gears, some cases, don’t make sense, since disappears. It identify areas remain relevant 21st century. First all, these transmission latest other science. These include: new materials gears; forms tooth profiles longitudinal without technological restrictions; drive based on indirect indicators - spectrum noise thermal fields housings. Also, working body, such as chain conveyors pumps, will never lose relevance. Or, train combines number functions, example, worm elevators, reduce angular velocity serve fuse.
