The Theory and Practice of Worm Gear Drives

Abstract

1.Introduction history of worm driving: list of symbols 2.Literature review 3.Production geometry of helicoidal surfaces having constant pitch Production development of worm gears having arched profile: General kinematic and mathematical model and examination of production geometry of helicoid surfaces having constant pitch: Geometrical analysis of hobs used for manufacture of ring gears mating with cylindrical or conical worms. 4.General form of mathematical modelling required. 5.Grinding wheel dressing required Equipment based on mechanical principle: General CNC operated equipment. 6.Inspection and measurement 7. Production of helicoid surfaces in intelligent systems Production of helicoid surfaces: Intelligent automation design and production of worm gears: Measurement and inspection: Universal thread grinding machine. 8.Main featutures of worm gearing for powertransmission Examination of mating in driving pairs: Main industrial features: Noise level in power transmission 9. Selection of appropriate worm gearing
