Geometry generation principle and meshing properties of a new gear drive

Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2018
The generation principle of composite cycloid is proposed for the tooth profile of external drive. Firstly, a two-link mechanism is developed as the equivalent mechanism to describe the geometric principle of cycloid by introducing the motion ...

UNDERCUT AND TOOTH PROFILE MODIFICATION OF DOUBLE HELICAL PULLEY

Jixie qiangdu, 2017
As for the smooth problems in the conjugate surface arising from hob tooth root and flank arc edge during the processing of new double helical synchronous belt’s pulley,the broken line generation mechanism at the conjugate tooth profile was investigated ...

Multidimensional Small Baseline Subset (MSBAS) Software for Constrained and Unconstrained Deformation Analysis of Partially Coherent DInSAR and Speckle Offset Data

Canadian Journal of Remote Sensing
Differential Interferometric Synthetic Aperture Radar (DInSAR) and speckle offset data are used to measure ground deformation. Computing deformation time series from these data can be challenging due to varying radar line-of-sight acquisition geometry ...
