Abstract:
A testing apparatus for minimizing runout of a rotating assembly includes a measurement device and a runout evaluator. The measurement device measures a distance to a surface. The runout evaluator obtains a first runout of a surface of a first member of the rotating assembly from the measurement device. The first runout has a magnitude and a phase. The runout evaluator obtains a second runout of a surface of a second member of the rotating assembly from the measurement device. The second runout has a magnitude and a phase. The runout evaluator determines a rotational position of the first member relative to the second member which results in a reduced runout of the rotating assembly. The determination of the rotational position is based on the magnitude and the phase of the first runout and the magnitude and the phase of the second runout.
Abstract:
A runout gauge has a mounting block, a support block that slides horizontally relative to the mounting block, a spring that pushes the support block away from the mounting block, a roller that rotates on a horizontal axle on the support block, and a dial indicator that mounts on the mounting block. The dial indicator has a plunger that contacts the support block. A vertically adjustable stand positions gauge with the roller against the tire tread and radial runout pushes the support block which pushes the plunger. A narrow roller is used to measure lateral runout.
Abstract:
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.
Abstract:
The disclosure herein relates to a wheel service machine, such as a wheel balancer, which provides audible output for guiding an operator to measured positions on a vehicle wheel assembly where corrective operations must be performed, such as the application of wheel assembly unbalance compensation weights.
Abstract:
A balancing method and apparatus by which a direct readout of the amount of unbalance is provided in order than an operator can determine from a meter reading how much weight to add to an unbalanced body and where to position it. Apparatus for weighing the rotatable workpiece is included as an integral part of the unbalance detecting mechanism with means for attenuating the readout meter signal in accordance with the body weight so that the meter will give an accurate indication of the amount of unbalance in weight times rotational radius units when the body is rotated at a predetermined proportion of the resonant speed of the system.

Abstract:
The machine determines, by first measurement sensor means (30), the axial position of at least one transverse balancing plane (P1, P2) in which the operator chooses to apply a respective balancing mass, and the radial position of points on the application surface (11a) corresponding with said balancing plane (P1, P2), while the machine monitors the angular position of the body (10); the body (10) is rotated and by suitable means the machine determines the imbalance means together with the data originating from the first and second sensor means, the value of each balancing mass and the position of its point of application on the application surface (11a) being determined. According to the invention, images originating from the application surface (11a) on the body (10) are acquired by an image acquisition means, said images being displayed on a screen (61 ) accessible to the operator, on the screen there also being indicated the position of application of the balancing mass in relation to the image of the application surface (11 a) which appears on it, for application of the balancing masses the body (10) being brought into an angular position such that the point of application of the masses falls within any region of the field visible on the screen (61).
Abstract:
A wheel balancer (1) for balancing an allow 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 centre 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.
