Abstract: An oil transfer assembly supplies oil into a moving, rotating tube extending along an axis. The assembly is provided with a support plate transversal to the axis and a sleeve, which is angularly fixed with respect to the support plate, it is configured to be coupled in a sliding and watertight way to a terminal section of the inlet of said tube and has at least one chamber for transferring oil into said terminal section of the inlet. The assembly is also equipped with at least two tubular bodies, which project axially from the support plate, define between them an annular channel communicating with the chamber and join the sleeve to the support plate in a watertight manner and with clearances so as to leave freedom of orientation of the sleeve around any direction orthogonal to the axis.

Abstract: A testing rig has a fixed supporting structure, a motor device controlled to drive a shaft portion about a rotation axis, and a misalignment applying unit for applying a parallel offset to a portion of a transmission element that, in use, is under test. The misalignment applying unit is provided with a connecting member, designed to be fastened to the portion of the transmission element in a coaxial position along an axis, and with an eccentric bushing which is connected to the connecting member by an inner bearing in a rotational manner about such axis. The bushing is connected to the fixed supporting structure by an outer bearing in a rotational manner about a further axis which is parallel and eccentric. An actuator device is controlled to rotate the bushing with respect to the fixed supporting structure.
