Developments in or relating to the balancing of a rotating assemblyA rotating arrangement comprising a rotating assembly mounted on an associated bearing defining a geometric axis of rotation for the rotating assembly, the rotating assembly comprisingJohn Michael Harrison...
A method is provided of rotationally balancing a rotating part. A rotor hub or ring and a plurality of rotor blades for assembly onto the hub or ring are provided, each blade having an unfilled internal cavity. The respective masses and moment weights of the blades with filled internal cavitie...
A balancing machine is a sophisticated tool used to measure and correct the balance of rotating machine parts, like wheels or rotors, ensuring smooth operation and longevity. By pinpointing imbalances, it prevents vibration and wear, crucial for machinery health. Intrigued by how precise balancing en...
combinations of a car. It means, the weight of one wheel assembly which consists of one wheel and the tyre it holds, should remain in equilibrium with all other wheel assemblies of a car. If such equilibrium is not maintained, it can hamper the drive quality and damage the suspension of ...
A device for limiting an unbalance in inside a centrifugal, with an electric motor to drive a rotating component disposed in an enclosure around a rotational axis, wherein a rotor of the electric motor is non-rotatably connected to the rotating component, a bearing assembly for the rotor and...
Apparatus for monitoring and balancing the axial load on the rotor assembly (12) of a rotating machine. The apparatus comprises an adjustable balancing means (45) for applying a controlled axial force on the rotor assembly, a flow circuit (53 or 54) for applying a pressurized fluid against a...
a means to engage the arbor shaft into the frame, tool-less quick-changeover arbors of a locking ball and ramp design, arbors that act as a means of a hand-hold for transport, and arbors for non-traditional rotating member mounting to address the issue of thin cross-sectional wheel ...

certain types of unbalance were simpler to detect since spurious vibrations of the flywheel were transmitted through the gyroscope assembly and could induce vibrations in a transducer. However, in the flexure-suspended gyroscope, most of the smaller vibrations are damped out by the flexure hinge; tha...
It is known from the state of the art that components of gas turbines rotating at considerable speeds must be balanced. In particular, partial components are separately balanced and then assembled. The state of the art shows here in particular bolted flange connections used to connect a turbine ...
