Disclosed is a method for balancing the out-of-balance of a shaft/wheel assembly. The balancing method involves a step of measuring the value of the out-of-balance of a wheel/shaft assembly with respect to a longitudinal axis of the mechanical shaft, and then measuring the position of at least two different target zones present on the surface of the wheel. The method involves removing material from the surface of the vaned wheel in order to reduce the value of the out-of-balance of the shaft/wheel assembly depending on the measurements taken in steps a) and b). In this way, the balancing method is much more precise compared with the prior art.

Methods of balancing a workpiece, in which the workpiece is rotated about an axis of rotation. The forces and/or torques that result from an unbalance of the workpiece during the rotation of the workpiece are measured, and material is removed from the workpiece to reduce the unbalance. The method includes removal of material from the rotating workpiece during measuring or as the workpiece is continuously rotated between measuring and material removal.

A rotor for a fluid machine includes a wheel that is supported for rotation about an axis of rotation. The wheel includes a back wall with an outer rim edge. The rotor also includes a plurality of blades that are attached to the back wall and that are spaced apart about the axis of rotation. Moreover, the rotor includes an inter-blade area on the back wall between neighboring ones of the plurality of blades. Furthermore, the rotor includes a balancing feature that is included in the inter-blade area on the back wall. The balancing feature intersects and defines part of the outer rim edge.

A vehicle wheel buffing stand has a first side support frame and a second side support frame spaced from the first side support frame. A first roller extends between the first side support frame and the second side support frame and the first roller is operably connected to the first side support frame and the second side support frame. A second roller extends between the first side support frame and the second side support frame, and the second roller is operably connected to the first side support frame and the second side support frame. The second roller is spaced from the first roller. The stand is configured to receive a vehicle wheel wherein the first roller and the second roller are configured to engage the vehicle wheel and rotatably support the vehicle wheel wherein an operator can rotate the vehicle wheel via rotation of the first roller and the second roller and to prepare surfaces of the vehicle wheel in preparation for mounting a tire on the vehicle wheel.

A method dynamically balances a rotational body. First, the rotational body is set into rotation and then an imbalance of the rotational body is determined. According to the determined imbalance, material of the rotational body is removed and/or additional material is applied to the rotational body. The removal and/or the application is carried out by a laser beam of a laser.
