Meshing Theory of ZC1 Worm Drive

Volume 10: 2019 International Power Transmission and Gearing Conference, 2019
Abstract The toroidal enveloping cylindrical worm drive, also called the ZC1 worm drive, is grinded by the toroidal grinding wheel. In this paper, the meshing theory for this worm drive is systematically established. According to this meshing theory, the meshing function, the meshing limit function, the equations of the worm helicoid and

Meshing theory of mismatched ZC1 worm drive

Mechanism and Machine Theory, 2020
Abstract The main purpose of this article is to investigate the meshing theory for the mismatched ZC1 worm drive. The contact endpoints, the datum point, and the internal instantaneous contact points are all determined by solving their corresponding nonlinear equation sets iteratively.

Mesh-Oriented Line Drawings Theory (MOLD Theory)

IEEE Transactions on Pattern Analysis and Machine Intelligence, 1986
In this paper, we describe a new model of bilevel digital images of line drawings. The key idea is that the constraints of generating the line drawings are available to select patterns which are considered to be a certain local appearance of line drawings. Concretely, when a bilevel digital image of line drawings is observed by 3 × 3 pixels' unit mesh,

UNSTRUCTURED MESH GENERATION: THEORY, PRACTICE, AND PERSPECTIVES

International Journal of Computational Geometry & Applications, 2000
Mesh generation is a great example of inter-disciplinary research. Its development is built upon advances in computational and combinatorial geometry, data structures, numerical analysis, and scientific applications. Its success is justified not only by mathematical proofs about the quality and the numerical relevancy of geometry-based meshing ...

Mesh Theory for Toroidal Drive

Journal of Mechanical Design, 2003
In this study, a simpler mesh equation for the toroidal drive is developed. Based on the equation, equations of the contact line, the limit curves, the induced normal curvature between the mating surfaces and the angle of the relative velocity vector to the contact line are introduced.
