ARTICULATED CV JOINT FOR POWER TRANSMISSIONS AND JOINT ASSEMBLY COMPRISING THE CV JOINT

摘要

An articulated CV joint for power transmissions comprises a head (4) having first means (5) for connection with one of a driving machine and an operating machine and a containment shell (6), a spherical body (8) movably housed into the shell (6) and having second connecting means (9) to the other of the driving machine and the operating machine, a first gear element (10) solidal with the spherical body (8) and provided with a first conical toothing (11), a second gear element (12) solidal with the shell (6) and provided with a second conical toothing (13) adapted to mesh with the first conical toothing (11) to allow the spherical body (8) to rotate about a first axis of rotation (X). The second gear element (12) comprises a pair of rollers (14, 15) solidal with each other and rotatable about a common second axis of rotation (Y) orthogonal to the first (X) and having respective second conical toothed surfaces (13', 13") defining respective portions of the second conical toothing (13) and adapted to simultaneously mesh with the first conical toothing (11) to allow the rotation of the first axis (X) about the second axis (Y) solidal with the spherical body (8).
