Meshing analysis and optimization for plane-generated enveloping toroid hourglass worm drive

Journal of Mechanical Science and Technology, 2021
Optimal design parameter combination and transmission optimization for plane-generated enveloping toroid hourglass worm drive are proposed. The modeling frame and mathematical model of the worm were constructed first to provide a perfect transmission.

Meshing performance investigations on a novel point-contact hourglass worm drive with backlash-adjustable

Mechanism and Machine Theory, 2020
Abstract To satisfy the increasing requirements of high-precision and high bearing capacity in industrial robot and aerospace technology, a novel point-contact hourglass worm drive consisting of an involute helical beveloid (IHB) gear and an oblique planar enveloping (OPE) hourglass worm is proposed in this paper.

Tooth flank modification theory of dual-torus double-enveloping hourglass worm drives

CAD Computer Aided Design, 2011
In this paper, the theory of tooth flank modification is enriched and developed for a double-enveloping toroidal worm drive. The goal and significance of the modification are expounded from the point of view of changing the tooth flank configuration for the worm gear pair.

Study on the evolving law of meshing performance of a novel self-evolution hourglass worm drive

Proceedings of the Institution of Mechanical Engineers, Part C: Journal of Mechanical Engineering Science
Under the extreme service requirements, a novel self-evolution hourglass worm drive has been proposed, and this transmission form has both precision and heavy-load characteristics. In this paper, to fully grasp the transmission characteristics, the evolving law of macro and micro meshing performances is studied.

Computerized simulation of tooth contact and error sensitivity investigation for ease-off hourglass worm drives

CAD Computer Aided Design, 2012
In the present paper, the tooth contact characteristics and the error sensitivity of the ease-off dual-torus double-enveloping hourglass worm drive (the DTT worm drive) are considered. The ease-off hourglass worm drive is composed of a standard hourglass worm and a modified worm wheel.

A General Modification Theory for Double-Enveloping Hourglass Worm Drives

Key Engineering Materials, 2011
A universal modification theory is developed for all kinds of hourglass worm drives, no matter what shape the generating surface of the worm is. Based on the theory established, toroidal worm drives can be classified into two main categories: with singular points and without singular points.
