20090205420 | RUNOUT GAUGE - 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. | 08-20-2009 |
20100000320 | METHOD AND APPARATUS FOR QUANTITATIVELY DETECTING UNBALANCED STATE AND METHOD FOR DETECTING CLAMPING STATE OF A WORKPIECE - A method and an apparatus for quantitatively detecting the unbalanced state of a rotating shaft and a clamping state of a workpiece clamped to a shaft are disclosed by solving with a nonlinear multivariable method a Lagrange kinematics equation to determine from acquired position, velocity, acceleration and torque signals of the rotating shaft an unbalanced amplitude variable and an unbalanced angle variable of the rotating shaft, optionally both with and without a workpiece. The motor driving the shaft is energized with a combined S-shaped and sinusoidal velocity profile with a position profile component, a velocity profile component, and an acceleration profile component. The components are selected such that the motor speed during the accelerating and decelerating stages does not change abruptly. | 01-07-2010 |
20100064802 | ROTOR CLOCKING BAR AND METHOD OF USE - A clocking bar includes a rod and an indicator located along a length of the rod, wherein the indicator has a pair of indication components with a predetermined spacing therebetween. The bar also includes a hole one locator located along the length of the rod, and a rear hole locator located along the length of the rod. The clocking bar is configured to identify a stack bolt hole one from among a plurality of bolt holes on a rotor through use of a relationship between physical features of the rotor. | 03-18-2010 |
20100170340 | CLAMPING FLANGE - A clamping flange that is designed to press a rim of a vehicle wheel against a flange of a shaft of a balancing machine and has a clamping plate with a plurality of recesses for accommodating centering bolts and a central opening to be slid onto the shaft of the balancing machine. The centering bolts can be inserted into the front of the clamping plate. The clamping flange is slidable onto the shaft while a clamping arrangement is provided for centering the clamping flange on the shaft. The clamping arrangement encompasses a clamping sleeve which is mounted in the central opening so as to be movable in an axial direction relative to the clamping plate. The clamping sleeve is movble into a clamping position by applying a pressure acting in an axial direction. In the clamping position, the clamping sleeve is mounted without play on the shaft and clamping flange. | 07-08-2010 |
20110083505 | Balance Test Indexing Tool for Balance-Testing a Rotor - A balance test indexing tool for use in a balance testing machine to assist a user in testing unbalance in a rotor. The tool includes a rotor mount that is temporarily affixed to the rotor being tested. The tool also includes a rotor mount receiver configured to receive the rotor mount and the rotor in the balance testing machine. The rotor mount and rotor mount receiver are configured to provide an indexing coupling that allows the rotor to be readily indexed to any of a plurality of index positions for unbalance testing in the testing machine. The tool allows multiple balancing runs to be made with relatively little effort needed to re-index the rotor. In some embodiments the tool includes a kinematic coupling that provides highly accurate and repeatable indexing. | 04-14-2011 |
20110252885 | Balance Test Indexing Tool for Balance-Testing a Rotor - A balance test indexing tool for use in a balance testing machine to assist a user in testing unbalance in a rotor. The tool includes a rotor mount face disposed on the rotor being tested. The rotor mount face may be machined in a surface of the rotor or provided in a separate rotor mount temporarily fixed to the rotor. The tool also includes a rotor mount receiver configured to receive the rotor mount face in the balance testing machine. The rotor mount face and rotor mount receiver are configured to provide an indexing coupling that allows the rotor to be readily indexed to any of a plurality of index positions for unbalance testing in the testing machine. The tool allows multiple balancing runs to be made with relatively little effort needed to re-index the rotor. In some embodiments the tool includes a kinematic coupling that provides highly accurate and repeatable indexing. | 10-20-2011 |

20150346048 | METHOD AND DEVICE FOR DETERMINING A MACHINING AXIS - In order to determine the machining axis of a rotatable workpiece blank, a reference workpiece, which has bearing surfaces concentric to its imbalance reference axis, and subsequently a workpiece blank are received in a measurement device, and as yet unmachined surface regions of the reference workpiece and of the workpiece blank are measured by a sensor device, and the measured position data are stored by a computer as a reference partial surface and a blank partial surface in a data storage device. The computer calculates deviations between the blank partial surface and the reference partial surface and, from these, an imbalance effect which is expressed by the position of the main axis of inertia of a given workpiece. The machining axis is calculated by adding an offset to the position of the main axis of inertia, which offset has been empirically determined with the aid of the actual imbalances of previously produced workpieces measured relative to the machining axis. | 12-03-2015 |
