Thompson Coupling

- The Thompson constant velocity joint (TCVJ) assembles two cardan joints within each other to eliminate the intermediate shaft. A control yoke is added to keep the input and output shafts aligned. The control yoke uses a spherical pantograph scissor mechanism to bisect the angle between the input and output shafts and to maintain the joints at a relative phase angle of zero. The alignment ensures constant angular velocity at all joint angles. Eliminating the intermediate shaft and keeping the input shafts aligned in the homokinetic plane greatly reduces the induced shear stresses and vibration inherent in double cardan shafts. - Two different models of the joint were uploaded in this project with their renderings and animations. Make sure to check both. - Dimensions are approximated as a result this should be used only for demonstration purposes. - Higher quality animations can be viewed here: Cross type: http://imgur.com/a/nJUYQ Ring type: http://imgur.com/a/h6ksJ
