Estimating the term…
The device comprises at least two annular balancing elements (10) each having an unbalance and disposed in axial side by side relationship and coaxial with each other on the rotating body (6) to be balanced. The annular elements (10) are rotatable with the rotating body (6) but can be angularly rotated relative to the body (6) during rotation thereof. For this purpose, at least one pair of nozzles (16) is provided for sending fluid jets, in particular air or cooling liquid jets, onto the annular elements (10) tangentially thereof, more specifically onto radial fins of the annular elements (10), to temporarily speed them up or slow them down with respect to the rotating body (6), until reaching of an angular position at which the resultant unbalance vector of the annular elements (10) compensates for the unbalance vector of the rotating body (6).
A balancing device for a rotating body, comprising at least two annular balancing elements each having an unbalance, said annular elements being disposed in axial side by side relationship and coaxial with each other on said rotating body and being rotatable with said body, and angular-positioning means associated with said annular elements for angularly rotating said annular elements relative to said body, wherein said positioning means comprises means for generating a fluid flow direction onto said annular elements to temporarily and selectively speed up and slow down rotation of said annular elements relative to said rotating body.
A balancing device for a rotating body, comprising at least two annular balancing elements each having an unbalance, said annular elements being disposed in axial side by side relationship and coaxial with each other on said rotating body and being rotatable with said rotating body, and angular-positions means associated with said annular elements for angularly rotating said annular elements relative to said body, said annular elements comprising respective rolling bearings and said rolling bearings have rolling elements of different mass along different circumferential portions.
A balancing device for a rotating body, comprising at least two annular balancing elements each having an unbalance, said annular elements being disposed in axial side by side relationship and coaxial with each other on said rotating body and being rotatable with said rotating body, and angular-positioning means associated with said annular elements for angularly rotating said annular elements relative to said body, said annular elements comprising respective rolling bearings and said rolling bearing having rolling elements along at least one circumferential portion and being devoid of rolling elements along at least another circumferential portion.
