Constant-Velocity Shaft Couplings: A General Theory

Abstract

The theory here expounded reveals certain inescapable geometrical conditions with which all couplings must comply when they are required to reproduce at the output shaft, simultaneously and precisely, all angular input shaft displacements. Plunging-type linkage couplings, whose geometrical forms follow very simply from the theory, are fully listed for both intersecting and parallel shafts. Many, particularly those for parallel shafts, are entirely new, and it is believed that there could be useful precision-engineering applications.

Kinematic Simulation of a Spatial Staggered Joint Based on COSMOSMotion

“…The Tracta joint, invented by Fenaille, has been used in European front-wheel drive automobiles, American allwheel drive military vehicles and some other applications. Hunt [11], Fischer and Remington [12] investigated its constant velocity transmission characteristics.…”

On the Correctness and Strictness of the Position and Orientation Characteristic Equation for Topological Structure Design of Robot Mechanisms

“…Over the years, there were two well-established methods for topological structure synthesis of parallel mechanisms, i.e., the screw theory based method [1][2][3][4][5][6][7][8][9][10][11][12][13] and the displacement subgroup based method [14][15][16][17][18][19][20][21][22][23][24][25][26].…”

Internal Displacements and Effects of Manufacturing Errors in the Clemens Coupling*

“…It is also noted that the Clemens coupling with ideal proportions functions as a constant-velocity shaft coupling resulting from the mechanism being arranged symmetrically about a joint in a central plane. This central plane is called the homokinetic plane by Myard [4] and further discussed by Hunt [5] and by Fischer and Remington [6].…”
