  • Patent number: 10948057
    Abstract: A ball screw drive having a threaded spindle and a spindle nut which coaxially encloses it at least partially. The spindle nut receives a ball deflector and therefore has an imbalance caused thereby. A force transmission element is positively connected to the spindle nut. The outer surface of the spindle nut has a recess which is dimensioned and arranged to serve as a stop or groove for the force transmission element and also contributes to the imbalance compensation of the spindle nut. An imbalance compensation method is also provided by fixing the action surface as a surface recess such that the smallest width of the recess is at least 3 times as large as the maximum radial indentation thereof. The filling up of at least parts of the recess by the force transmission element is accounted for and the recess is lengthened along the spindle nut for imbalance reduction.

  • Patent number: 10024763
    Abstract: Methods and systems for improving the uniformity of a tire by determining one or more high speed uniformity parameters of the tire are provided. The high speed uniformity parameters can be determined by continuously acquiring uniformity data while ramping the tire to and from high speeds. For instance, measured uniformity data can be continuously collected for the tire as the tire is increased to high rotational speeds and decreased from high rotational speeds. The measured uniformity data can then be analyzed to determine one or more high speed uniformity parameters for the tire. For instance, the measured uniformity data can be corrected for non-high speed uniformity contributions to the uniformity measurements, such as contributions resulting from non-uniformity of a road wheel use to load the tire during uniformity testing, contributions resulting from mass unbalance of the tire, and contributions from low speed uniformity parameters of the tire.

  • Patent number: 9587512
    Abstract: A method for balancing rotating machinery, such as gas turbine engines, to minimize vibrations. The method involves operation of the engine for a period of time at varying power levels and ranges of other operational parameters representative of the system operating envelope to obtain vibration data (amplitude and phase) for the full range of dynamic responses of interest. This usually includes time at elevated power settings until the engine reaches thermal stability, altitude variation, etc. as well as the full engine operating range. The full set of vibration data measured during the engine run is analyzed to generate unique unbalance states. The unique unbalance states are then analyzed and the mean unbalance state is identified. Balancing masses can then be installed or removed in accordance with a balance solution that is equal and opposite to the mean unbalance state.

    Abstract: A method for efficiently operating a vehicle wheel balancing system having a wheel mounting structure upon which a vehicle wheel assembly is mounted for rotation during a measurement or service procedure, and a load roller assembly disposed in operative proximity to the wheel mounting structure for engaging a surface of the vehicle wheel assembly and applying a controlled load there to during rotation. After mounting a vehicle wheel assembly to the mounting structure, the wheel assembly is rotationally driven and a measurement of imbalance is initially acquired and the results displayed to an operator. Subsequently, the load roller assembly is engaged with the still rotating wheel, while measurements of radial forces and/or runout of the wheel are acquired, before the wheel rotation is stopped.

  • Patent number: 8863573
    Abstract: A method of dynamically balancing a shaft for multiple rotational speeds comprising: rotating the shaft in the balancer at a first rotational speed while measuring a first force and a first angle of a first shaft imbalance measurement; rotating the shaft at a predetermined second rotational speed while measuring a second force and a second angle of a second shaft imbalance measurement; comparing the first shaft imbalance measurement to a first predetermined imbalance specification and comparing the second shaft imbalance measurement to a second predetermined imbalance specification; if the first shaft imbalance does not meet the first predetermined imbalance specification or the second shaft imbalance does not meet the second predetermined imbalance specification, then calculating a composite correction based on the first and second shaft imbalance measurements; and applying a first weight to the shaft at a correction first angle based on the calculated composite correction.

  • Patent number: 8813288
    Abstract: Systems and methods for detecting an out of balance condition for a washing machine are disclosed. The wash basket of the washing machine is rotated at a constant predetermined rotational speed. If the washing machine has an unbalanced load, the wash tub will strike the cabinet as the basket rotates in the wash tub. The tub strikes cause the wash basket to lose momentum. The inverter drive control system causes the inverter to provide more current through the motor phases to the motor to maintain constant speed. From the value of the current, the severity of the tub strikes during a test period can be determined. An out of balance condition can be detected and measured based at least in part on the severity of the tub strikes.

  • Publication number: 20140165721
    Abstract: A vehicle wheel balancer system having a processing system and a spindle shaft upon which a vehicle wheel assembly is mounted for measurement of imbalance characteristics and forces. The processing system is configured with software instructions to evaluate the remaining imbalance present in a vehicle wheel assembly following the application of imbalance correction weights, and to determine if the remaining imbalance is the result of the vehicle wheel assembly having deviated from an expected rotational position during the time between the measurement of the imbalance and the application of the imbalance correction weights. In the event of such a deviation, the processing system is further configured to provide the operator with a suitable warning to evaluate and correct the mounting of the vehicle wheel assembly before proceeding to rebalance or re-measure the vehicle wheel assembly.
