Abstract
An apparatus for balancing a rotating body, in particular the grinding wheel of a grinding machine, comprises an assembly secured to the grinding wheel and rotating with it, with masses having an adjustable arrangement, electrical motors for controlling adjusting movements of the masses, and electrical circuits with a microprocessor unit. A transceiver terminal between a control unit and the rotating assembly provides a first contactless transmission channel for inductively coupling a fixed power source to the rotating parts, and a second contactless transmission channel for transmitting information in both directions. The second transmission channel may comprise optoelectronic devices.
Claims17
An apparatus for the dynamic balancing of a body rotating about a longitudinal axis with respect to a support comprising:
- an assembly fixed to and rotating with said body, said assembly comprising
- at least one mass the position of which is adjustable, and
- at least one electric motor connected to adjust the position of the mass;
- a control unit;
- a power supply source;
- and
- a transceiver unit positioned between said assembly and both the control unit and the power supply source,
- said assembly further comprising circuitry electrically connected to said electric motor for providing signals controlling the motor and thus the displacement and position of the mass, said transceiver unit comprising:
- a first contactless transmission channel coupling the power supply source to the rotating assembly to thereby supply the rotating assembly with power, and
- at least a second contactless transmission channel between the control unit and said circuitry,
- wherein the first transmission channel comprises an electromagnetic coupling, and the second transmission channel is distinct from the first transmission channel and enables a transmission of signals in both directions between the control unit and the circuitry.
