| 101 | Unbalance phase display device | JP13278083 | 1983-07-22 | JPS6025432A | 1985-02-08 | SAKAGUCHI YOSHIMASA; NOMURA MINORU |
| PURPOSE:To read a real unbalance phase difference on a display part directly by adding a DC voltage corresponding to a previously calculated coefficient of influence to an apparent DC phase signal which is detected. CONSTITUTION:An oscillation detector 3 detects the oscillation of the bearing 2 of a rotating body 1, and an unbalance component is extracted from the oscillation signal V0 and compared with an angle reference signal PS synchronizing with the rotation of the rotating body 1 to lead out the phase difference signal S of the unbalance. Then, this DC phase difference signal S and the output signal (d) of a DC voltage generating circuit 6 which generates a DC voltage corresponding to the previously detected phase of the coefficient P of influence are inputted to an adding means 7, which outputs a compensated phase value. The 1st and the 2nd comparators 13 and 14 turn on when the output voltage from the 1st adding circuit 12 exceeds voltages corresponding to + or -180 deg., and the output of the 1st adding circuit 12 is inputted to a display part 8 as it is in other cases. | ||||||

| PURPOSE:To make it possible to perform accurate second correction, by providing two component operating circuits, and selectively using each circuit in correspondence with the direction of unbalanced vector, without duplicating first and second corrected points even for a body under test having the odd number of correcting directions. CONSTITUTION:An unbalanced-vector detecting device 1 receives a detected unbalanced signal (a), which is obtained by detecting vibrations and the like caused by the rotation of a body under test; and a reference phase signal (b), which is obtained by detecting the marker on the body under test by a photocell and the like. Based on the magnitude and direction of the unbalance of the body under test, the unbalanced vector is detected and outputted. The output is introduced into first-and second-component operating circuits 2 and 3 and a judging circuit 4. The first and second component operating circuits 2 and 3 resolve the inputted vector into two component vectors in the preset directions and output the result. A phase shifting circuit 5 is connected to the second component operating circuit 3, which can shift the setting direction of the component vectors. | ||||||
| 103 | Automatic positioning apparatus for unbalanced angle in dynamic balance tester | JP18875482 | 1982-10-26 | JPS5977327A | 1984-05-02 | YAMAMOTO MASATO |
| PURPOSE:To shorten the positioning time, by rotating a body under test in the specified direction from a reference position to a position of an unbalanced angle at one surface, stopping the rotation, then rotating the body under test in the same direction from the stopped position to a position of an unbalanced angle on the other surface, and stopping rotation. CONSTITUTION:Unbalanced angles thetaL and thetaR on the right and left surfaces with respect to the reference position of a body under test are stored in memory circuits 3 and 4, respectively. At first, the body under test is rotated in the specified direction for positioning of the angle thetaL on the left surface by a pulse motor 10. A comparator circuit 6 stops the motor 10 when the input from the circuit 3 agrees with the rotary angle of the motor 10. Then the positioning of the angle thetaR of the right surface is performed. At this time, the motor 10 is rotated by thetaR-thetaL when thetaR>thetaL from the stopped position to the same direction at the positioning of the left surface. The motor 10 is rotated by 360 deg.+thetaR-thetaL when OR<OL. The positioning and stopping are performed by the same way. | ||||||

| PURPOSE:To provide a stable device of high economic efficiency by separating a position determining signal and a position detecting signal by using a rotary disc having no positioning holes and one piece of photodetector. CONSTITUTION:A rotator 11 is formed with plural pieces of holes D in the positions equally dividing the circumference near its outside circumference and no hole is formed at one place. A photodetector 10 includes one piece of light source 13 and one piece of photodetector 15 and is dispposed opposite to the holes D with the disc 11 in-between. The output (a) of the photodetector 10 is applied via inverters 17, 19 to the clock terminal of a D type fli-flop 21. The D type FF21 operates as a monostable multivibrator together with a CR element. A D type FF27 operates similarly to the FF21 as well. The Q2 output signal and the output signal (c) of the inverter 19 are applied to the input terminal of an OR gate 33, and the output signal thereof is a position detecting signal VA. The output signal of the inverter 19 and the Q3 output signal of a monostable multivibrator 37 are applied to the input of an AND gate 39, and the output signal of the gate 39 is positioning signal VB. | ||||||

| 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. | ||||||

| The invention relates to a method for balancing rotors, in particular rotors pertaining to toolholders of metal-cutting machine tools. According to the inventive method, the balance error of the rotor is determined in a balancing machine computer with respect to size and direction, and is compensated by spreading at least two compensating elements with defined balance error to corresponding adjustment positions. First of all, the adjustment positions of the compensating elements are determined from the measured balance error of the rotor, and from the extent of the balance error of the compensating elements. The rotor is then rotated in the balancing machine until a compensation position is attained, in which the adjustment position of one of the balance elements is in a predetermined position in relation to the balancing machine. When the rotor is in the compensating position, a visible marking is made on the compensating element. Said element is then set to its adjustment position by making a mark on the starting element coincide with the visible marking. These last steps are repeated for the other compensating element. The device for balancing rotors has a marking device which is controlled by the computer and places visible markings on the compensating elements when the rotor is in its compensating position. This is when the adjustment positions of the compensating elements are in a predetermined position in relation to the balancing machine. | ||||||
