Description

  The present invention relates to a composite rotating body device including a first rotating body unit and a second rotating body unit that can be applied to, for example, a rotating electrical machine test.

  In order to perform a test of a rotating electrical machine such as a motor or a generator (for example, a test for measuring the relationship between the rotation angle of the rotating shaft and the maximum current value or the torque), the first rotating body unit and the second rotating body A compound rotating body device having a unit may be used. An example of the first rotating body unit includes a rotating electrical machine and a torque detector (torque meter) coupled to the rotating shaft of the rotating electrical machine. An example of the second rotating body unit is a speed reducer such as a worm gear mechanism for controlling the rotation angle of the rotating shaft of the rotating electrical machine. A torque is generated in the rotating electrical machine by supplying electric power to the rotating electrical machine, and the input shaft of the speed reducer is handled in a state where the rotation of the rotating electrical machine is constrained by the output shaft of the speed reducer (worm gear mechanism). The relationship between the rotation angle of the rotating electrical machine and the torque or the maximum current value is measured by rotating it little by little.

  In order to perform the test of the rotating electrical machine with high accuracy, it is desired to suppress as much as possible the influence of misalignment between the center of the rotating shaft of the first rotating body unit and the center of the rotating shaft of the second rotating body unit. For this reason, the conventional composite rotating body device has a coupling between the first rotating shaft and the second rotating shaft in order to allow misalignment between the first rotating shaft and the second rotating shaft. Was established.

  Alternatively, it is conceivable to use a centering device in order to minimize the misalignment between the first rotating shaft and the second rotating shaft. For example, Patent Document 1 describes an example of a centering device. However, since the centering device of Patent Document 1 requires that the subject is a cylindrical member such as a nozzle or a pipe, the rotating shaft members such as the output shaft of a rotating electrical machine or a speed reducer It is difficult to use for centering.

  When a coupling is provided between the first rotating shaft and the second rotating shaft, it is inevitable that a certain amount of backlash exists in the rotation direction of the coupling. Couplings that reduce backlash as much as possible (so-called non-backlash type couplings) have also been proposed, but if high torque generated in a high-power rotating electrical machine is loaded on the coupling, minute backlash occurs. End up. For this reason, when high torque is applied, angular distortion in the rotational direction is generated, which affects the angle measurement of the rotating electrical machine and causes a decrease in the reliability of the test results. For this reason, it is desired to perform the test in a state where the first rotating shaft and the second rotating shaft are directly connected without using a coupling. However, when the coupling is not used, centering (centering) between the first rotating shaft and the second rotating shaft has to be performed as accurately as possible.

  Therefore, an object of the present invention is to perform centering (centering) of the first rotating shaft and the second rotating shaft, so that the first rotating body unit and the second rotating shaft can be used without using a coupling.

FIG. 7 is a front view of the measurement unit shown in FIG. 6.

  Hereinafter, a composite rotating body device according to one embodiment will be described with reference to FIGS. 1 to 7. FIG. 1 is a perspective view of a composite rotating body device 1 used when testing a rotating electrical machine such as an electric motor or a generator. 2 is a side view showing a part of the composite rotator apparatus 1 in cross section, and FIG. 3 is a plan view of the composite rotator apparatus 1.

  The composite rotating body device 1 includes a base 10 having a substantially horizontal reference surface 10a, a first rotating body unit 11 mounted on the base 10, and a first base mounted on the base 10. 2 rotary body units 12, a braking mechanism 13, and the like. The base 10 is flat and is made of a material having high rigidity so as not to be substantially deformed even when an assumed load is applied.

  The first rotating body unit 11 includes a first base member 20, a rotating electrical machine 21 such as a motor or a generator mounted on the first base member 20, and a torque detector 22. The rotating electrical machine 21 is supported by the support portion 20 a of the first base member 20. The torque detector 22 is coupled in series to the rotating shaft 21a on the rotating electrical machine 21 side.

  The first rotating body unit 11 includes a first rotating shaft 25 that is coaxial with the torque detector 22. The first rotating shaft 25 rotates around the first axis C1. The first axis C1 extends in a direction along the substantially horizontal reference plane 10a. The torque detector 22 detects torque generated by the rotating electrical machine 21 in a state where electric power is supplied to the rotating electrical machine 21.

  A first guide portion 30 is provided between the base 10 and the first base member 20. The first guide unit 30 is such that the first rotating body unit 11 moves along the reference plane 10a in a direction perpendicular to the first axis C1 (horizontal directions Y1 and Y2 shown in FIGS. 1 and 3). Has a function of guiding. That is, the first rotating body unit 11 can move in the direction (horizontal directions Y1, Y2) perpendicular to the first axis C1 along the reference plane 10a, and does not move in the direction along the first axis C1. Is mounted on the reference plane 10a.

  An example of the first guide portion 30 is a guide groove 31 extending in a direction (horizontal direction Y1, Y2) perpendicular to the first axis C1, and a slide member that is fitted so as to be relatively movable in the length direction of the guide groove 31. 32. For example, a guide groove 31 is formed in the first base member 20, and a slide member 32 is attached to the base 10. On the contrary, the guide groove 31 may be formed in the base 10 and the slide member 32 may be attached to the first base member 20.

  The first base member 20 is fixed to the base 10 by bolts 35 that function as first fixing means. When the bolt 35 is loosened or removed, the first base member 20 can move in the horizontal directions Y1 and Y2 with respect to the reference surface 10a. That is, in a state where the first base member 20 is not fixed to the base 10, the first rotating body unit 11 moves in the horizontal directions Y <b> 1 and Y <b> 2 (direction along the reference surface 10 a) along the guide groove 31. Can do. A long hole 36 (a part of which is shown in FIG. 4) through which the bolt 35 passes is formed in the base 10.

  A first adjusting mechanism 40 is provided between the base 10 and the first rotating body unit 11. FIG. 4 is a cross-sectional view of the first adjustment mechanism 40 along the horizontal direction. The first adjusting mechanism 40 has a function of adjusting the positions of the first rotating body unit 11 in the horizontal directions Y1 and Y2 with respect to the base 10. An example of the first adjustment mechanism 40 includes a first adjustment screw member 41, a fixed-side female screw member 42, and a moving-side female screw member 43. The first adjusting screw member 41 extends in the horizontal directions Y1 and Y2 along the reference surface 10a. The fixed-side female screw member 42 is fixed to the base 10 by a screw member 44. The moving-side female screw member 43 is fixed to the first base member 20 by a screw member 45.

  As shown in FIG. 4, the first adjusting screw member 41 includes a first male screw portion 41a having a first pitch P1, a second male screw portion 41b having a second pitch P2, and an operation portion 41c. have. The second pitch P2 is smaller than the first pitch P1. The second male screw portion 41b is formed on the tip side of the first male screw portion 41a. The operation unit 41c has a shape that can be rotated by a tool such as a wrench.

  The first male screw portion 41a is screwed into the screw hole 42a of the female screw member 42 on the fixed side. The second male screw portion 41 b is screwed into the moving-side female screw member 43. The outer diameter of the second male screw portion 41b is smaller than the outer diameter of the first male screw portion 41a. Since each of the first male screw portion 41a and the second male screw portion 41b is a single thread screw, when the first adjusting screw member 41 is rotated once, the thread of the first male screw portion 41a and the second thread The distance (lead) that the thread of the male thread portion 41b travels in the axial direction is equal to the pitches P1 and P2, respectively.

  Therefore, when the first adjustment screw member 41 is rotated in the first direction R1, the first adjustment screw member 41 is fixed on the fixed-side female screw member 42 in accordance with the first pitch P1 and the rotation amount. Is advanced by the first distance L1. On the other hand, the moving-side female screw member 43 screwed into the second male screw portion 41b is in the direction indicated by the arrow L2 with respect to the first adjusting screw member 41 in accordance with the second pitch P2. Retreat relatively. Here, since the first pitch P1 is larger than the second pitch P2, the distance L1 that the first adjustment screw member 41 rotates and moves in the forward direction is relatively moved by the female screw member 43 on the moving side in the backward direction. It is larger than the distance L2. Therefore, the first base member 20 moves forward in the horizontal direction Y1 by the difference (distance L3) between the moving distance L1 in the forward direction and the moving distance L2 in the backward direction. Therefore, the first base member 20 can be moved by a minute distance L3.

  Contrary to the above, when the first adjustment screw member 41 is rotated in the second direction R2, the first adjustment screw member 41 moves backward by a distance corresponding to the first pitch P1 and the rotation amount. . On the other hand, the moving-side female screw member 43 screwed into the second male screw portion 41b moves forward relative to the first adjustment screw member 41 by a distance corresponding to the second pitch P2. Therefore, the first base member 20 moves backward in the horizontal direction Y2 by a distance corresponding to the difference between the moving distance in the forward direction and the moving distance in the backward direction.

  As described above, the first adjustment mechanism 40 has a simple configuration using the single adjustment screw member 41, and can finely adjust the positions of the first rotating body unit 11 in the horizontal directions Y1 and Y2. . After the position of the first rotating body unit 11 in the horizontal direction Y1, Y2 is adjusted, the first rotating body unit 11 is fixed to the base 10 by a bolt 35 as a first fixing means.

  An example of the second rotating body unit 12 is a speed reducer 51 including a worm gear mechanism 50 that receives the torque of the rotating electrical machine 21. The speed reducer 51 includes a housing 52, an input shaft 53, a handle 54 that rotates the input shaft 53, a worm 55 attached to the input shaft 53, a worm wheel 56 that meshes with the worm 55, and the worm wheel 56. And a second rotating shaft 57 that rotates in the direction.

  The second rotation shaft 57 rotates around the second axis C2 on the extension line of the first axis C1. The second rotating shaft 57 is also an output shaft of the worm gear mechanism 50. The second rotating shaft 57 is movable in the axial directions X1 and X2 (shown in FIGS. 1 and 6) along the key groove 58 parallel to the second axis C2 with respect to the housing 52 of the speed reducer 51. .

  A second guide portion 60 is provided between the base 10 and the second rotating body unit 12. The second guide unit 60 guides the base 10 to move the second rotating body unit 12 in the vertical direction (indicated by arrows Z1 and Z2 in FIGS. 1 and 5).

  An example of the second guide portion 60 includes a guide hole 61 that extends in the vertical direction and a shaft member 62 that is fitted to the guide hole 61 so as to be relatively movable in the vertical direction. The guide hole 61 is formed in the second base member 65. The shaft member 62 is fixed to the base 10. That is, the second rotating body unit 12 is mounted on the reference surface 10a so as to be movable in the vertical direction with respect to the base 10 and not to move in the horizontal directions Y1 and Y2. The guide hole 61 may be formed in the base 10 and the shaft member 62 may be fixed to the second base member 65.

  A second adjustment mechanism 70 is provided between the base 10 and the second rotating body unit 12. The second adjustment mechanism 70 has a function of adjusting the relative position in the vertical direction of the second rotating body unit 12 with respect to the base 10.

  An example of the second adjustment mechanism 70 is provided on the lower surface of the second base member 65 and the taper member 71 movable in the first horizontal direction F1 and the second direction F2 (shown in FIG. 5). The taper receiving surface 72 and the screw mechanism 73 that moves the taper member 71 in the first direction F1 and the second direction F2 are provided. The upper surface of the taper member 71 is a taper surface 71c whose height changes (decreases) at a constant inclination angle α1 from one end 71a to the other end 71b of the taper member 71. On the other hand, the height of the tapered receiving surface 72 changes from one end 65a of the second base member 65 toward the other end 65b at an inclination angle corresponding to the tapered surface 71c. The taper receiving surface 72 is in contact with the taper surface 71c.

  The screw mechanism 73 of the second adjustment mechanism 70 includes a holder member 74 provided on the base 10, a second adjustment screw member 75 rotatably supported by the holder member 74, and a second adjustment screw. An operation portion 76 that rotates the member 75 and a screw hole 77 formed in one end 71a of the taper member 71 are configured. A second adjustment screw member 75 is screwed into the screw hole 77. The second adjusting screw member 75 is held by a holder member 74 so as to be rotatable and not moved in the axial direction. For this reason, when the second adjustment screw member 75 is rotated by the operating portion 76, the taper member 71 is moved in the first direction (forward direction) F1 or the second direction (retracted) according to the rotation direction and the rotation amount. Direction) F2.

  A through hole 78 is formed in the taper member 71 along the longitudinal direction of the taper member 71. Since the shaft member 62 is inserted into the through hole 78, the taper member 71 has the first direction F1 and the second direction F2. Can be moved to. When the taper member 71 moves in the first direction F1, the second rotating body unit 12 moves in a direction in which the height of the second rotating body unit 12 increases (the direction indicated by the arrow Z1 in FIG. 5) according to the movement amount. When the taper member 71 moves in the second direction F2, the second rotary body unit 12 moves in a direction in which the height of the second rotating body unit 12 decreases (the direction indicated by the arrow Z2 in FIG. 5) according to the amount of movement. After the height of the second rotating body unit 12 is adjusted in this way, the second rotating body unit 12 is fixed to the base 10 by the bolt 79 as the second fixing means.

  As shown in FIGS. 2 and 3, the first rotation shaft 25 and the second rotation shaft 57 are coupled to each other via a coupling portion 80. The coupling portion 80 includes a first flange 81 formed at the end of the first rotating shaft 25, a second flange 82 formed at the end of the second rotating shaft 57, and the first flange 81. And the second flange 82 and the like with a bolt 83 or the like. The first flange 81 and the second flange 82 face each other. In this way, the first rotating shaft 25 and the second rotating shaft 57 are directly connected without providing a coupling therebetween, so that a so-called “coupling-less” coupling structure is established. The coupling portion 80 is covered with a cover member 85 for safety.

  The braking mechanism 13 includes a disk 90 that rotates integrally with the second rotation shaft 57, a stopper member 91 that is fixed to the base 10, a fixed braking member 92 that is provided on the stopper member 91, and the base 10. A clamp base member 93 fixed to the clamp base member 93, a moving brake member 94 provided on the clamp base member 93, a clamp lever 95 for operating the moving brake member 94, a cover member 96, and the like. Yes. By operating the clamp lever 95 and pressing the moving-side braking member 94 against the disk 90, the rotation of the disk 90 can be restrained.

  Since the torque generated by the rotating electrical machine 21 is received by the worm gear mechanism 50, even if the torque of the rotating electrical machine 21 is input to the second rotating shaft 57, it is possible to substantially suppress the rotation of the second rotating shaft 57. . However, there is a possibility that the second rotating shaft 57 may rotate when vibrations of the rotating electrical machine 21 are transmitted to the worm gear mechanism 50. In the present embodiment, the braking mechanism 13 that restrains the rotation of the second rotating shaft 57 is provided, so that the rotation of the disk 90 is restrained by the braking member 94 even when the vibration of the rotating electrical machine 21 acts on the worm gear mechanism 50. By doing so, it is possible to prevent the second rotation shaft 57 from rotating. If the rotation of the second rotating shaft is constrained by the braking mechanism 13, it is possible to reduce the impact load on the worm gear mechanism 50 when the rotating electrical machine 21 is activated.

  FIG. 6 shows a state in which the measuring unit 100 is attached to the second rotating shaft 57 with the coupling portion 80 disconnected. FIG. 7 is a front view of the measurement unit 100. The measurement unit 100 includes a frame 102 that is fixed to the end surface of the flange 82 of the second rotating shaft 57 by a bolt 101, and a measurement gauge 103 that is supported by the frame 102. A display unit 104 is provided in the measurement gauge 103.

  Since the measurement gauge 103 is attached to the second rotation shaft 57 in this way, the measurement gauge 103 rotates relative to the circumferential direction of the first rotation shaft 25 when the second rotation shaft 57 rotates. be able to. In a state where the contact 105 of the measurement gauge 103 is in contact with the peripheral surface of the first rotating shaft 25 (the detected portion 25a shown in FIG. 6), the position of the contact 105 is displayed on the display unit 104.

  The detected portion 25 a of this embodiment is the outer peripheral surface of the flange 81 of the first rotating shaft 25. For this reason, the outer peripheral surface (detected portion 25a) of the flange 81 is processed with high accuracy so as to be a perfect circle concentric with the first axis X1. The detected portion 25a may be formed on the inner peripheral surface of the flange 81 of the first rotating shaft 25. The detected portion 25a and the measurement unit 100 function as measurement means for detecting a relative positional deviation between the first axis C1 and the second axis C2.

Below, the process of centering (centering) the first rotating shaft 25 and the second rotating shaft 57 will be described.
As shown in FIG. 6, the connecting portion 80 between the first rotating shaft 25 and the second rotating shaft 57 is disconnected, and the measuring unit 100 is attached to the second rotating shaft 57. When the input shaft 53 of the speed reducer 51 is rotated by the handle 54 in this state, the second rotation shaft 57 rotates around the second axis C2 via the worm gear mechanism 50. For this reason, the measurement unit 100 also rotates around the second axis C2. At this time, the first rotating shaft 25 is stopped.

  For example, as shown in FIG. 7, the measurement unit 100 is moved to a horizontal first position S1, a second position S2 opposite to 180 °, an upper third position S3, and a lower fourth position. It can be rotated to position S4. In the first position S1 and the second position S2, the position where the contact 105 is in contact is displayed on the display unit 104, whereby the horizontal axis between the first axis C1 and the second axis C2 is displayed. A deviation is detected. Similarly, in the third position S3 and the fourth position S4, the position where the detected part 25a is in contact is displayed on the display unit 104, so that the first axis C1 and the second axis C2 in the vertical direction are displayed. Misalignment is detected.

  As a centering work procedure, first, the first rotating body unit 11 is horizontally centered with respect to the second rotating body unit 12, and after the first rotating body unit 11 is fixed, the first rotating body unit 11 is fixed. The second rotating body unit 12 is vertically aligned with respect to the rotating body unit 11. The reason is that when the first rotating body unit 11 is tightened in the vertical direction by the bolt 35, the height of the first rotating body unit 11 slightly decreases as the bolt 35 is tightened. If the second rotating body unit 12 is centered in the vertical direction after the first rotating body unit 11 is fixed by the bolt 35, the vertical position of the first rotating body unit 11 by tightening the bolt 35 will be described. No need to be affected by misalignment.

  The centering of the first rotating body unit 11 in the horizontal direction is performed with the first fixing means (bolt 35) loosened. Based on the loosened bolt 35, the operation portion 41c of the adjustment screw member 41 of the first adjustment mechanism 40 is moved in the first direction R1 or the second direction R2 (shown in FIG. 4) with a tool such as a wrench. Rotate to While the measurement unit 100 confirms the relative displacement in the horizontal direction of the first axis C1 with respect to the second axis C2, the horizontal positions of the first axis C1 and the second axis C2 are matched. In addition, the first rotating mechanism unit 11 is moved in the horizontal direction by a minute amount by the first adjusting mechanism 40. When the positions of the first axis C1 and the second axis C2 in the horizontal direction match, the first rotating body unit 11 is fixed to the base 10 with the bolt 35.

  The centering of the second rotating body unit 12 in the vertical direction is performed with the second fixing means (bolt 79) loosened. Under the state where the bolt 79 is loosened, the taper member 71 is moved in the first direction F1 or the second direction F2 by rotating the operation portion 76 of the second adjustment screw member 75 with a tool such as a wrench. By moving, the height of the second rotating body unit 12 is finely adjusted. While confirming the relative positional deviation in the vertical direction between the first axis C1 and the second axis C2 with the measurement unit 100, the vertical positions of the first axis C1 and the second axis C2 are matched. The second rotating body unit 12 is moved by a minute amount in the vertical direction by the second adjusting mechanism 70. When the vertical positions of the first axis C1 and the second axis C2 match, the second rotating body unit 12 is fixed to the base 10 with bolts 79.

  An example of the test of the rotating electrical machine 21 is that torque is generated by supplying electric power to the rotating electrical machine 21, and the handle 54 is moved under a state where the rotation of the rotating electrical machine 21 is restricted by the worm gear mechanism 50 of the speed reducer 51. By operating, the input shaft 53 of the speed reducer 51 is rotated little by little, and the rotating electrical machine 21 is rotated. Since the rotation angle of the rotating electrical machine 21 is detected by an angle detector such as a resolver, the magnitude of the torque that changes according to the rotation angle of the rotating electrical machine 21 is detected by the torque detector 22. Further, the maximum current value of the electric power supplied to the rotating electrical machine 21 is measured.

  According to the composite rotating body device 1 of the present embodiment, centering (centering) between the rotating shaft 25 of the first rotating body unit 11 and the rotating shaft 57 of the second rotating body unit 12 is performed in the first manner. This can be performed by the adjustment mechanism 40 and the second adjustment mechanism 70. For this reason, it becomes possible to directly connect the first rotating shaft 25 and the second rotating shaft 57 without using a coupling, and to solve the problems of the conventional apparatus using the coupling (for example, measurement variations due to angular distortion). I was able to.

  In addition, the composite rotating body device 1 according to the present embodiment has the first adjustment screw member 41 from one side of the base 10 (the side on which the first adjustment mechanism 40 and the second adjustment mechanism 70 are arranged). By adjusting the second adjustment screw member 75, horizontal centering and vertical centering can be performed, so that the centering operation can be performed safely and easily.

  The first fixing means for fixing the first rotating body unit 11 may be other than the bolt 35. In short, it is only necessary that the first rotating body unit 11 centered in the horizontal direction can be fixed to the base 10. Further, the second fixing means for fixing the second rotating body unit 12 may be other than the bolt 79. In short, it is sufficient that the second rotating body unit 12 centered in the vertical direction can be fixed to the base 10.

  The first rotating body unit 11 may be a rotating device other than the rotating electrical machine 21 such as an electric motor or a generator, or may include a rotating device other than the torque detector 22. The second rotating body unit 12 may be a rotating device other than the speed reducer 51. In short, centering is desired, including a first rotating unit having a first rotating shaft and a second rotating body unit having a second rotating shaft that rotates on an extension of the axis of the first rotating shaft. Any composite rotating body device may be used.
