This paper is identifying tendencies of future development of the gears and of general use and special geared transmissions. Tendencies are estimated on the basis of top research ideas, tendencies of technology and "state of the art" achievements in companies specialised in mechanical transmissions. At cylindrical gears : technological method application for fitting within the ME class [DIN] of the admissible stress diagrams ; topological corrections, high toothing gears with integer contact ratio, re-launching non-involute gears in the new technological background offered by the possibility of grinding and checking any profiles. At worm gears : numerically controlled contact localising using 3-4 optimising parameters, double-enveloping worm gears with grindable worm by means of an internal mobility procedure. Also the paper identifies possible development tendencies of gear transmissions : general use speed reducers, custom-made gearboxes (for power plants, mining, ships, cement industry), special multipliers, geared motors, variable speed transmissions, drives for robots and machine tools.
