Modeling and Contact Strength Analysis for Modified Cylindrical Gear Profile with Arcuate Tooth Trace

Jixie chuandong, 2015
Based on analyzing the meshing theory of ideal gear and the tooth surface equation,the tooth surface equation of modified cylindrical gear profile with arcuate tooth trace is deduced.

A study on hourglass-worm gearings with arcuate tooth profiles. The curvature effects on the constitution of the surface of contact.

TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series C, 1990
The most conventional hourglass-worm gear has a tooth profile of a straight type. This paper introduces an arcuate profile in the hourglass-worm gearing. The worm gear tooth surface is treated as being generated by a torus-shaped grinding wheel that has a circular axial section, and the effects of the radius of the axial section on the constitution of ...

A study on hourglass-worm gearings with arcuate tooth profiles. Tooth bearings resulting from the displacement of the gear axes under load.

TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series C, 1990
Owing to the displacement of the gear axes, the worm and wheel seldom operate in their theoretical relative positions. Hence, on practically used hourglass-worm gearings, tooth contacts shift to the boundaries of the tooth surfaced, resulting in edge contact and extreme conditions of load.

A study on hourglass-worm gearings designed to concentrate surface normals. A gear disign using an hourglass-worm gearing with an arcuate tooth profile.

TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series C, 1990
In order to avoid the influence of the displacement of gear axes under load upon tooth contact, the authors propose that a projective group of the surface normals should be concentrated upon the intersection point of the plane perpendicular to the wheel axis and the axis about which the worm axis rotates, displacing its position relative to the wheel ...
