摘要:
A rotating mass dynamic balancing device, in particular for grinding wheels, including: a support body (2) having a central axle (8), two compensation masses (7a, 7b) mobile onto said support body (2) and having a development direction parallel to said central axle (8) and a section, perpendicularly to said development direction, engaging a part of space angularly limited, said compensation masses (7a, 7b) showing compensation barycenters laying all in a same barycentric plane (10), and driving means (11) suitable for translating each of said compensation masses (7a, 7b) in angular direction, with respect to said central axle (8), starting from balancing positions, in which said compensation masses (7a, 7b) are diametrally opposed with one another with respect to said central axle (8).

It is provided a feeler (1) for workpieces (40) being machined comprising a rocking arm (20) adapted to feel the workpiece (40), a first sensor (31) adapted to measure the position of the rocking arm (20) and at least one additional sensor (32) operatively connected to the rocking arm (20) and adapted to detect external perturbations acting on the feeler (1).
摘要:
A device (1) for balancing rotors (3) by material removal is disclosed, which comprises a milling tool (18) provided with a first and a second cutting regions (18a, 18B) disposed transversely of each other, to remove material in the presence of feed movements for cutting, directed both radially of a rotor (3) and tangentially of the outer surface (4) of the rotor (3), and comprising support and relative-movement means (2) for positioning and moving the milling tool (18) and rotor (3) relative to each other, which means engages the rotor (3) in a manner adapted to cause rotation of said rotor about its rotation axis (5) even while the milling tool (18) is removing material from the rotor (3).
摘要:
Balancing device (1) suitable for being positioned integrally to a rotating body (20) suitable to be placed in rotation around a rotation axis (20a), comprising a plurality of storage means (2) arranged in positions offset to the main rotation axis (20a), at least one element suitable for winding (3) wound in correspondence with a plurality of storage means (2), transfer means (4) suitable to wind the elements suitable for winding (3) around storage means (2) and to consequently vary the distribution of the mass of the elements suitable for winding (3) over several storage means (2) so as to balance the mass of said rotating body (20).
摘要:
L'invention concerne un dispositif d'équilibrage dynamique et pondéral pour machines à rotor, comportant au moins un rotor (4) porté par un arbre tournant (5), au moins une unité d'équilibrage pondéral (20,21) portée par ledit arbre, et au moins un système de contrôle et de correction de l'état de déséquilibre du rotor (4), ledit système étant apte à agir en permanence sur la ou les unité(s) d'équilibrage (20,21) lorsque le rotor (4) est en rotation caractérisé en ce que: l'unité d'équilibrage pondéral (20,21) est située à une distance axiale du rotor et comprend au moins deux masses d'équilibrage montées déplaçables indépendamment l'une de l'autre sous l'action de moyens d'entraînement commandés par le système de contrôle et de correction, lesdites masses se déplaçant selon des trajectoires formant un circuit fermé autour de l'arbre tournant (5).
