<p>A HOMOKINETIC JOINT ALLOWING A LARGE ANGULAR DISPLACEMENT. The joint comprises a first member defining a tripod connected to a first shaft and forming three trunnions. Part-spherical rollers are respectively slidably and rotatably mounted on the trunnions. A second member connected to a second shaft defines three raceways in which the rollers are received. The raceways are each formed by a pair of part-circular sectioned grooves the mean line of which is an arc of a circle centered preferably in the vicinity of the axis of the second shaft. The tripod is rigid with a shaft section which has, in a zone close to the tripod, a substantially triangular crosssectional shape approximately constituting the envelope of the free edge of the second member when the joint operates with an angular displacement of the first and second shafts close to the maximum possible angle.</p> |
