RT Journal Article SR Electronic A1 Medvecká-Beňová, Silvia T1 Meshing Condition and Kinematic Properties of non-circular Gear JF Acta Mechanica Slovaca YR 2016 VO 20 IS 2 SP 16 OP 21 DO 10.21496/ams.2016.010 UL https://www.actamechanica.sk/artkey/ams-201602-0002.php AB The gearing with changing transmission gear ratio are used in the practice, even though the "standard" gearing with constant transmission gear ratio are used more often. The article examines the mesh conditions proposed in elliptical gears, as I speed and power ratios in this proposed gearings. The work is devoted to the analysis of these kinematic conditions in the proposed gearings and examines their differences from "standard" ring gear transmission with a constant transference number. The problem is solved for elliptical, eccentric gear with a continuously variable gear ratio to a range from 0.5 through 1 to 2.
