Rzeppa Joint

grabcad

- A Rzeppa joint consists of a spherical inner with 6 grooves in it, and a similar enveloping outer shell. Each groove guides one ball. The input shaft fits in the centre of a large, steel, star-shaped gear (inner race) that nests inside a circular cage. The cage is spherical and has six openings around the perimeter. This cage and gear fit into a grooved cup. Six large steel balls sit inside the cup grooves and fit into the cage openings, nestled in the grooves of the star gear. This joint can accommodate the large changes of angle when the front wheels are turned by the steering system; This design allows up to 45° of articulation.- 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:Birfield type: http://imgur.com/a/uzcOHCross-grooves type: http://imgur.com/a/W79hA
