Synthesis of the base curves for n-lobed noncircular bevel gears
Mechanical Sciences, 2020 As a type of spatial transmission mechanism, noncircular bevel gears can transfer power and motion between two intersecting axes with variable transmission. In this paper, the relation of arc length is expressed by Angle in spatial polar coordinate system, utilizing the spherical triangle theorem, the parametric equations of base curves are established

Generation of Noncircular Spiral Bevel Gears by Face-Milling Method
Journal of Manufacturing Science and Engineering, Transactions of the ASME, 2016Noncircular bevel gears are applied in variable-speed transmissions with intersecting axes. Since dedicated machines for manufacturing noncircular bevel gears are not available, noncircular bevel gears are normally manufactured using universal computer numerically controlled (CNC) machining centers, resulting in poor productivity.

Noncircular Bevel Gear Transmission With Intersecting Axes
Journal of Mechanical Design, 2008Noncircular bevel gear can achieve variable transmission between intersecting axes. Based on polar coordinates, a design method for noncircular bevel gears is presented. The geometric characteristic of tooth profiles of the gears can be obtained by means of geometry principles for spherical engagement and a pair of conjugated crown racks, which can ...

The Research of Noncircular Bevel Gears’ Undercut Condition
Volume 11: Systems, Design, and Complexity, 2015Noncircular bevel gear (NBG) is a kind of gear which can transmit spatial variable transmission ratio motion directly. It has the advantages of compactness, smooth motion, and accurate transmission. There, however, exists an urgent problem that the NBGs’ exact undercut condition is unknown.
