Abstract

In a process for reducing the wobbling motion in a rotating rotor body (1) which is mounted so as to be freely floating and which has relfecting surfaces (13) at its outer circumference, a measurement beam (5) with a given position of incidence is reflected by the reflecting surfaces (13) of the rotating rotor body (1) which pass by and, after reflection, is directed onto a position detector (17) whose signals are supplied to a computer (22). This computer (22) determines the difference between the greatest and the smallest value of the signals emitted by the position detector (17) during a complete revolution of the rotor body (1) and the angular positions of the rotor body (1) associated with both values and, from the latter, calculates control signals for the correction device (16). During the revolution or during a subsequent revolution of the rotor body (1), this correction device (16) causes a change of the distribution of mass at the rotor body (1) in a noncontacting manner and without influencing the reflecting surfaces (13) in such a way that the difference between the smallest and greatest value of the signals emitted by the position detector (17) which was determined during this revolution of the rotor body (1) is smaller than the difference which was determined during the preceding revolution. The description also concerns an arrangement for carrying out such a process.

Description

460686, description of the invention (1) The present invention is directed to a method for supplying and trembling the rotor body. The second & one is installed as a free-floating rotation. The other is installed as a free-floating device for implementing such a method. The axis of rotation is related to its rotation: the child, which has a -space stable rotation, and it is not re-determined by any dragon's angular momentum axis and the main inert axis. If the rotor body is two = step = when used, the main body of the main inertia axis is-a completely uniform structure of the 1 scale body, the symmetry must be complete, and the axis of rotation, and its symmetry axis green reentry, the main inert axis Because of the unavoidable material, ^ :: manufacturing tolerance, the actual rotor post: nature, manufacturing inaccuracy, and little deviation from this ideal situation, does not correspond to this ideal situation. Or, the rotation of the floating bearing device: the main inert axis (such as an unrestricted 糸 〇. When the interference torque is outside the bamboo field) is no longer retained with the axis of symmetry of the rotor body = retained angular momentum, which leads to the total system, then Because the whole fa; ί axis. As long as there is no other external force, the position of the angular momentum axis moves away from the main cone: it will be fixed to the direction. In this case, the rotor's 'Angular Momentum Axis Empty: Cone Envelope' around the angular momentum ^ ^^ The axis is also called a "rolling drive": For example, if the system moves linearly in a polyhedron sweep, if the system , And because of the environmental implementation of the system, because the bearing and U do not use the corresponding construction force: fixed action on the rotor body; the results described above. 疋 size offset, it may be installed in the rigid body The bearing is thin = up. Usually, this rotating vehicle line is both a temple and the latter embossing a rotation axis `` overlap.

By properly changing the position of V in the rotor C, repositioning V can almost completely eliminate the mass distribution of the rotor (the force of the material used in the rotor body can be absorbed by the bearing device due to imbalance and solid bearing and dense bearing cushioning) , Can compensate the unbalanced shape, strong enough if the symmetry axis and the rotation axis are connected to each other. Error, and therefore cause, for example, mirror polyhedron movement, so strictly observe as much as possible! G > Six-D sinusoidal beam deflection. When tearing the body It is necessary to ensure the second line; the system itself achieves sufficient good coincidence. This is particularly important, for example, to make the mirror surface between the rotation axis. 'Civil mirror surface body, as for optics, however, although many people are committed to f-scanners The sub-assembly does not properly meet its requirements for I; :: Health: According to the requirements for the use of polyhedron brushes. For example, the imbalance W generated by the application and the position of the rotor in the fixed corner and the rotor on the fixed shaft are determined by the device. 4 ), In the area where the rotor body is unbalanced (drilling, grinding: the area of the child body, remove momentum as much as possible or in the Y-step process with the unbalanced phase: determine whether there is Enough :,] know. In-as soon as, or whether the procedure should continue.

Know-how, remove the imbalance by turning the V body 460686 V. Description of the invention (3) __ method, of which Material is removed from the rotor body for the purpose of balancing in an unbalanced device .: Shooting 4-position measurement is a known method here. Balance occurs in individual measuring devices, i fixes the bearing axis to the rotor body, where balance is actually used ^ The placement of a fixed bearing axis no longer corresponds exactly to the bearing ratio. However, this' for example, such a rotor body in the form of a mirror polyhedron is used by a floating bearing device, such as when an active magnetic shaft is used as a self-scanner, in Its own device uses a fixed bearing in advance: using the body-sweeping method, 4 in cooperation with the free-floating bearing device in actual use. Pre-J: J: to prevent the occurrence of axial vibration caused by chattering. The purpose of the invention is to propose a method for a rotating rotor body which is installed so as to float freely and effectively reduce unwanted ones. According to the present invention, this is provided by one being installed to become free floating and the other on its outer circumference.

Description of the invention (4) The poor way affects the reflecting surface until it is broken down by one ~ ^ ~ ^ In the method according to the present invention, the yield is lower than a predetermined minimum. The rotor body is rotated to reduce flutter and installed so as to float freely and determine its axis of rotation.罝, instead of borrowing a rigid shaft ^ fluid bearing, such as the 佴 self-bearing can be better 'but also the gas bearing axis used by the magnetic device is effective for the rotor body non-rigid bearing, you can-a way to cause the shaft to be determined size.

In the end, this leads to a large scale and can therefore be adapted or even phased: scanners, especially in applications where they are used, and their use in many aspects have considerable quality-related issues. β write the laser beam when projecting the furnace.

Description of the invention (5) Bearings produced by imbalance are rarely achieved with Si in the axis of rotation and symmetry. According to the present invention, according to the invention, 'Fruit overlaps better. The positions of the axes are coincident, and the objective can be achieved. J: The position of the axes is appropriate and symmetrical. The method according to the present invention is a great advantage of operation. Because the quality of the pendulum is finally affected, the process can be determined by the number of axial vibrations ^ and basically by the interaction steps implemented. In addition, according to the method of the present invention, i — state (free floating), The other advantage is that in the latter movement, it is exactly the same as this rotation; In this regard, the state in which the sheep will be used in the future can be completely free-floating while rotating; it is carried out according to the method of the present invention and even the device. a is located where it will be implemented so that the method according to the present invention can be turned on, and the position detector sends out: how much difference it takes to implement in the rotor body. For example, the power of the brain can be adjusted so that it can be used to control the correction device in a manner that is different from that caused by the difference. It can be compensated as completely as possible. At that time, the difference is as close as possible and / or the rotor is slowly rotated! # \ _Style to shape.

It is advantageous to provide-a mirror polyhedron or-a polyhedron 7 a ^,,, and a rotor body, and it is advantageous to provide a passive superconducting magnet bearing or a main f magnet bearing as a bearing device. However, in specific use cases: ΓΓ Another suitable bearing device, such as a fluid bearing (such as a gas to glaze bearing), is provided for a free floating bearing device. The invention is explained more fully below with reference to the drawings. FIG. 1 shows a schematic diagram of a device according to the present invention, in which a body scanner 'is used as a rotor, and it is arranged in a housing 2. Posterity-ring: central part 3 (Figure 2), which is provided with a plane parallel plate 4 as: ί, a transparent window of the measuring beam 5, which deflected the row and comes from-source 6 (in Figure 1 Very basic instructions only), such as a laser generator (Figure 2). The permanent magnetic mirror polyhedron 7 used in the polygon scanner 1 is inserted. In the cavity of the central part 3, the central part 3 is closed in a vacuum-tight manner by a base plate 8 and -moss at 9. The base plate 8 and the cover plate 9 are made of glass, and support a magnetic coil 10 for magnetic bearings, a magnetic coil 11 for a drive unit, and a permanent magnet using a permanent magnet system. The mirror polyhedron 7 and the base plate 8 or the cover plate 9 is touched, so it is impossible to damage the mirror surface, and it is arranged on the multiple surfaces of the mirror, and the peripheral reflection surface 1 3. The circle is provided for the initial operation. First, the axial position of the device is precisely adjusted, and then an electromagnetic rotary field is generated to rotate the mirror polyhedron γ. Relative to the rotation ',,; after 460686 V. Description of the Invention (ίο)-, the polyhedron 7 always generates a rotation axis AA in such a way that it corresponds to the mirror polyhedron from the line, where the situation of | always takes In the same manner, the position of the axis of rotation AA of the magnetic field housing 2 can be reproduced in w and 疋. However, f is usually aimed at the phase axis, the rotation axis AA of the facet 7 is intended to be aligned at 90 degrees relative to the main inertia to ensure the accuracy of the surface normal N of the mirror (Figure 2), The tremor of the mirror surface 13 of the mirror body 7. As a result, the multi-faceted magnet coils 10, 11 and cloth on the base plate 8 and the cover plate 9 are suitable for implementation in a completely symmetrical manner. Shuijiu magnet 12 points. Moreover, the device has a way to allow a free zone 丨 55, _ can properly reach the end face 27 of the mirror polyhedron 7, in order to affect the mass distribution of the mirror polyhedron 7 by means of in-situ ablation radiation ^ to ^ The amount of clams, or in the case of the center of rotation of the mirror polyhedron 7, is only applied. This is firstly-the distance measuring device 14, which provides patent No. 5,171,984 according to the example of the optical principle and has many detection mirrors. For example, according to the United States = measurement results, a signal is obtained for one master and two. To the components. The sleeve shaft is worn axially and the laser light of the correction device of the laser generator for the driving unit and the magnetic coil u & Its transmission—including the pulse of the pulse, S / ecology 1 6 (as a cutting or shaping thunder "may; Shi = Duosian surface (Γ; for rotation at rated speed), 89108688.ptd page 15 460686 V. Description of the invention (11) Partial removal of material. In this case, the periodic position deviation of the autonomous inert axis A_A caused by the normal N of __specified U: "mirror error" occurs in the least possible way. The control method is implemented in 7 ways. The deep position uses the laser ablation method used in this example, and when it is used on the quartz glass at a repetition rate of kilohertz (kHz), it can mine 1x10-7 cubic meters. Mm / pulse removal rate, which corresponds to a mass change of 2.

Nd-YAG-laser at a pulse length of 100 nanoseconds and a repetition rate of ikHz, when used in metal and silicon, once again achieves a removal rate of 1x7-7 mm3. The benefits are as follows: The removal of the material is performed on a plane, and the body 7 concave 'Λ may otherwise result in a > notch voltage that will negatively affect the intensity at multiple faces of the high-speed rotating mirror. Compared with other imaginable and usable methods for material displacement, such as, "evaporation", "reduction", "sputtering", chemical transformation (halidation, nitriding), ion implantation, etc., laser ablation The method is very large, and it does not actually affect the material characteristics and material composition of the mirror polyhedron 7, which is necessary because of heat treatment or a small amount of time. 4 Huandezheng has been found in the rotating mirror polyhedron 7. Therefore, the extreme stress of the road always leads to strength-related problems. ^ Also, the basic ^ 'can also use other such mu beams for the distribution of materials in the rotor body 1 to change the laser pulse on the surface 27 of the mirror = body 7 to deliberately impact a predetermined area 23, and The way that causes the material to be removed in this position is controlled at the rated rotation speed of the mirror polyhedron 7

89108688.ptd Page 16 46〇686 ———- V. Description of the invention (12) Degree 5 y = ^ For example, 1.3kHZ has difficulty. If this is implemented at the red rotation speed of the mirror polyhedron 7, this has the advantage that the state of the mirror polyhedron 7 is absolutely the same as that at the subsequent operation. Of course, the removal of the material does not necessarily have to be performed at the specified rotation speed of the mirror body 7, and the rotation speed does not affect the position of the main inert axis of the rotation line A A. For example, for extremely high-speed rotation, laser ablation of the mirror dihedron 7 can be performed much lower than its rated rotation speed; however, the rotation speed must be carefully adjusted in this case, which does not correspond to the vibrational rotation speed of the mirror 7. The specific example shown in the figure can also make the mirror polyhedron 7 rotate and cut: the pulse characteristics of the shot 16 are the same as #; In this respect, the synchronization accuracy will not be strict / required because In fact, it does not matter whether the maximum amplitude of the flutter error occurs in the material removal, or if it occurs at a smaller value (+ / _ 1〇.). In any case, due to the large number of lasers required, t f: the mean value is determined, and will continue to be obtained when the material is removed. The test immediately provides confirmation of the success of the process.舢 H ί The position of the normal 13 measured by the plane 13 is used as the measurement of the light source 6 by the Emperor's Eye 'on the polyhedron scanner i to be fixed at each of the positioning two bodies 7-the moving mirror 13 is reflected to a lion-array; Receiver line under test.
