| A wheel balancer (1) for balancing an alloy wheel (2) comprises a support housing (30) and a main shaft (36) onto which the wheel (2) is mounted. A sub-housing (35) rotatably carries the main shaft (36), imbalance forces in the main shaft (36) and their respective directions are monitored for determining the magnitude and angular positions of balance weights required for correcting imbalances in the wheel (2) in selected balancing planes (17) and (18). A telescoping extendible sensor arm (54) is pivotally mounted about a vertical pivot axis on the support housing (30) for detecting balance weight receiving locations on the inner surface (10) of a wheel hub (4) of the wheel (2) at the selected desired balancing planes (17) and (18). Balance weight positions (22) at which correcting balance weights (20) are to be attached to the inner surface (10) of the wheel hub (4) in the respective balancing planes (17) and (18) are indicated by a laser light source (70) which directs a pencil laser beam (72) at the inner surface (10) in the lower front quadrant (23) of the wheel hub (4) when the balance weight position (22) is aligned with the laser light source (70). A laser light dot formed on the inner surface (10) indicates the angular center line (21) of the balance weight position (22) and an inner side edge (25) of the balance weight position thereby indicating to the operator the precise position at which the correcting balance weight (20) is to be attached to the wheel hub. | ||||||

| A portable, hand-held, battery-powered rotor balancing calculator has a data port, which includes a host communications port to down-load set-up data from, and upload collected data to a host computer. A rotation sensor communications port receives data from the rotation sensor, and a vibration sensor communications port receives data from vibration sensors. An angle sensor communications port receives data from an angle sensor, and the calculator determines how far and in what direction the rotor has been rotated. The calculator also employs a power supply, a processor, and an operator interface. There is also a memory for data storage, menus with check-off lists, and procedures, including raw data screening procedures and collected data analysis procedures. A display is provided which depicts gathered data in a graphical form which is easily reconfigured for rotor viewing orientation. | ||||||
| 44 | Two-dimension unbalance correction device | US018036 | 1993-02-16 | US5450337A | 1995-09-12 | Chung Chuan-Yuan; Cuo Shy-Pyng |
| A two-dimension unbalance correction device, or a two-dimension balancing apparatus, is designed to correct a rotor by resolving the measured unbalance vector into a horizontal component and a vertical component, and then correcting the resolved components respectively. The balancing apparatus comprises a horizontal and a vertical balancing mechanism in the form of a symmetric correction disc, which is fixed to an end plane of the rotor and synchronously rotated therewith. The correction disc is engraved with a plurality of concentric circles, radial lines, and phase angles for indicating the magnitude and the phase angle of the unbalance vector during the correcting process. The balancing apparatus is further provided with a trial weight bolt, which cooperates with the trial screw for normalizing the linear scale of the correction disc and the vectermeter of the balancing apparatus. In performing the unbalance correction, a correction bolt, whose weight is a multiple or a fraction of the trial weight bolt is used in conjunction with the regulation slot at a proper position on the correction disc for correcting the unbalance vector on the vertical and/or the horizontal axis, respectively. | ||||||
| 45 | Dynamic vehicle tire and wheel balancing system | US497043 | 1983-05-23 | US4489607A | 1984-12-25 | Hyo-Sup Park |
| A dynamic vehicle wheel and tire balancing system with manual rotation of the shaft to which the wheel and tire is attached. A computer within the system receives entered premeasured values of wheel dimensions and are in response to the output of a rotational speed sensor determines a proper rotational speed of the shaft at which point it automatically decouples the manually operated crank from the wheel shaft so that there can be no externally applied disturbances for the subsequent measurements of imbalance. Twin spaced transducers along the shaft determine the wheel runout attributable to imbalances in both inner and outerwheel rims and the computer provides output signals indicative of the correct balance weight and the mounting positions of the weights on the wheel rim. | ||||||
| 46 | Method of and apparatus for balancing rotors | US935844 | 1978-08-22 | US4162634A | 1979-07-31 | Dionys Hofmann |
| A method and apparatus for balancing a rotor in at least one plane. The geometrical parameters of the rotor are stored along with test values representing the rotor in balance as determined during a test run. These stored values are transmitted to a frame computer which determines the size and phase relationship of counterweights necessary to balance the rotor. The test values resulting from the test run are stored for the entire duration of the balancing operation upstream of the frame computer. Also, the geometrical parameters of the rotor may be recalled and displayed at any time during the operation. | ||||||
| 47 | Read-out system for wheel balancer | US908401 | 1978-05-22 | US4155255A | 1979-05-22 | Donald R. Sherman; Donald B. Curchod; Albert L. Mitchell |
| A read-out system and method for a wheel balancing machine employs means for determining the minimum angular displacement between a "balance point" on the wheel and a predetermined reference for a stationary portion of the machine using a first scale of displacement and means for converting the minimum angular displacement from the first scale to a second scale. Using the second scale for indicating the balance point enhances the sensitivity of the display means at the balance point. A method is carried out for indicating alignment between the balance point where weight is to be added to an unbalanced wheel to balance same and a predetermined reference position for the machine. | ||||||
| 48 | Method and apparatus for ascertaining and indicating the angular position of an unbalance in a rotor | US736372 | 1976-10-28 | US4064761A | 1977-12-27 | Alfred Giers; Paul Holdinghausen; Hatto Schneider; Friedman Widmann |
| The unbalance angle is transformed into units of length or into non-dimensional units which are correlated to the body to be balanced, either to a circumference thereof, or to a characteristic scale of the body to be balanced. The unbalance position may then be displayed in such units. The apparatus for performing the method includes a transformation computer which transforms the measured angular value through at least one operant. Preferably, the apparatus also includes an indicator device for units of length or for non-dimensional units or angle representing units. | ||||||

| The present display device combines a liquid crystal display panel with a transparent dial for example having a polar coordinate system on which the information shown by the panel may be displayed with regard to its value and location or angular position. This type of display is especially suitable for displaying unbalance informations of a body to be balanced. In the present process an unbalance representing signals are separated into horizontal and vertical components, which are then supplied respectively to the row and column electrodes of said liquid crystal display device. The dial itself may also be constituted as a liquid crystal display panel. The row and column electrodes may be provided in several sets for simultaneously displaying several unbalance informations, for example, relating to different planes in a body to be balanced. | ||||||
