Claim:
1. An apparatus for measurement of the noisiness and of the vibrations of a rolling bearing having an outer ring and an inner ring mounted coaxial to each other with respect to an axis of symmetry (A) and between at least one crown of rolling bodies, comprising: a base; a first support supported by the base and having a slide slidingly supported by the base in a predetermined direction (D) and means removably supported by the slide, adapted to integrally receive a first one of the outer ring and the inner ring of the bearing, with the axis of symmetry (A) arranged parallel to the predetermined sliding direction (D) of the slide; a first and a second accelerometer accommodated into respective seats provided on the first support so that respective measurement axes (X, Y) of the accelerometers are arranged at a right angle relative to each other on a plane perpendicular to the axis of symmetry of the bearing; means for rotating at a predetermined speed a second one of the outer ring and the inner ring of the bearing; means for axially moving the slide along the predetermined direction (D) and for selectively applying, by the slide, a first and a second axial thrust (S data processing means for processing a first and a second electric signal (T wherein the means for rotating at the predetermined speed the second one of the outer ring and the inner ring includes an electric motor supported by the base, a second support supported in fixed position by the base in front of the first support and idly supports an annular driven element so that the annular driven element is coaxial to the axis of symmetry (A) of the bearing rings, the annular driven element having means for angularly integrally engaging the second one of the outer ring and the inner ring and motion transmission means from the electric motor to the annular driven element; the second support being crossed by an axial hole arranged coaxial to the axis of symmetry (A) of the bearing rings, wherein the means for angularly integrally engaging the second one of the outer ring and the inner ring includes an annular prong that axially overhangly extends from the second support and from the annular driven element and is adapted to angularly integrally receive the second one of the outer ring and the inner ring; and a ring that axially overhangly extends from the second support that is peripherally provided with seats for angularly integrally receiving fastening means of a flange of the second one of the outer ring and the inner ring; the annular prong and the ring being selectively mountable integral to the annular driven element, one at a time, into a same reception seat of the driven element.
