摘要： A system for balancing a rotary element involving two or more materials of different melting temperatures normally fixed in position relative to the rotary element. Heating of the materials first to a point above the highest melting temperature followed by cooling at optimum balance then reheating to a point above the next highest melting point followed by cooling at optimum balance and repeating the procedure for each material results in vernier balancing action, the masses of the various materials being selected to predetermine their effect on balance.

摘要： A workholder or roll-over fixture including a primary supporting structure and a pair of workholding elements mounted for rotation in the structure about a fixed axis of rotation and providing a work-receiving area therebetween. The workholder is particularly suitable for servicing and maintaining large and heavy machinery. The workholder includes a control system including a sensing means that is sensitive to out of balance forces within the workholder caused by rotation of the workpiece when held by the workholding elements and movement of the center of gravity of the workpiece relative to the axis of rotation. This control system also preferably includes a device mounted on one of the workholding elements which is adapted to sense the attitude thereof. The sensing means provides an output signal, which is sent through the attitude sensing device, indicative of the out of balance forces. Adjusting means are responsive to this output signal and effect positional adjustment of the workholding elements on the structure relative to the axis of rotation. This positional adjustment tends to decrease and remove the out of balance forces by moving the center of gravity closer to the axis of rotation. The preferred adjusting means include a hydraulic motor and lead screw mounted in and on each of the workholding elements.

摘要： A device (1) for receiving and clamping a rotor bearing (6) is provided with at least one bearing block (2) lying transversely to a bearing axis of the rotor bearing (6), a bearing element (4) designed to receive the rotor bearing (6), a clamping arm (12), and a locking device (9). The clamping arm (12) has an engagement element (8) by means of which it can be brought into engagement with the rotor bearing (6). The locking device (9) also comprises at least two engagement elements (8) which are radially movable in the bearing element (4) and can be introduced into radial receptacles (14) in the rotor bearing (6) by actuating the locking device (9), such that a rotor bearing (6) which can be received by the bearing element (4) can be clamped by the engagement elements (8) of the clamping arm (12) and the locking device (9).

摘要： A method for acquiring unbalance amount of a rotor, comprises: manufacturing a rotor where the rotational journal of the rotor forms the rotation axis of the rotor; mounting the connecting part to the rotational journal of the rotor to form an assembly where the connecting part forms the rotation axis of the assembly, the connecting part and the rotor can be rotated with a relative angle, and the relative position between the rotation axis of the rotor and the rotation axis of the rotor assembly is kept unchanged before and after the rotor and the connecting part are relatively rotated with the certain angle.

摘要： An angle-measuring device includes a housing and a position sensor configured to generate angle values indicating an angular position of a shaft with respect to a reference position. An interface is configured to communicate with subsequent electronics via a data channel. At least one imbalance sensor is configured to generate an imbalance signal from imbalance-induced excursions of the shaft. An imbalance analyzer is configured to generate imbalance values from the imbalance signal. A signal processor is configured to generate imbalance information from the angle values and the imbalance values. The imbalance information is transmittable through the interface to the subsequent electronics.
