Point-line Meshing Gear Drive
Point-line meshing gear is a new-styled gear characterized by both easy manufacturing and divisibility of involute gears and high strength for contacting between convex and concave tooth profiles of a circular-arc gear.And contact strength of point-line meshing gears has improved by 1~2 times in comparison with involute gears,and bending strength of such gears has improved by approximately 15%,while noise has decreased even by 5~10dB (A).In addition,with the increase of load,noise will decrease by 3~4 dB (A).Only a few teeth or even 2~3 teeth are required for a pinion gear.There are single point-line meshing gears (equivalent to single arc gear),double point-line meshing gears (equivalent to double arc gear) and few-tooth point-line meshing gears,totaling three kinds,which are widely used in reducers for metallurgy,mining,craning,transport and chemical industries.And the three kinds of gears can be converted into soft tooth-flank,medium tooth-flank and hard tooth-flank gears.Here the types,characters,meshing features and dimension calculation of point-line meshing gears are described.
