[0035] This invention provides a toroidal worm gear transmission detection device, see [link / reference]. Figures 1 to 3 , Figure 1 This is a schematic diagram of the structure of the toroidal worm gear transmission detection device. The toroidal worm gear transmission detection device includes: Z-axis guide rail 1, X-axis guide rail 2, Y-axis guide rail 3, Z-axis moving shaft 4, X-axis moving shaft 5, Y-axis moving shaft 6, driver 7, worm gear fixing seat, loader 9, worm wheel fixing seat, first parallel light source 11, second parallel light source 12, first standard shaft 24 and second standard shaft 25;

[0036] Z-axis guide rail 1 is vertically set, and Z-axis movable axis 4 is movably set on Z-axis guide rail 1;

[0037] Both the driver 7 and the worm gear fixing seat are located on the Z-axis moving axis 4. The driver 7 is used to drive the toroidal worm gear 18 to rotate.

[0038] The worm gear retainer is used to fix the first standard shaft 24 or the toroidal worm gear 18;

[0039] The X-axis guide rail 2 is set horizontally, and the X-axis movable axis 5 is movably set on the X-axis guide rail 2;

[0040] Y-axis guide rail 3 is longitudinally set on X-axis moving axis 5, and Y-axis moving axis 6 is movably set on Y-axis guide rail 3;

[0041] Both the loader 9 and the worm gear mounting base are located on the Y-axis moving shaft 6, and the loader 9 is used for transmission connection with the worm gear 19;

[0042] The worm gear mounting bracket is used to fix the worm gear 19 or the second standard shaft 25;

[0043] The first parallel light source 11 is disposed on any end face of the toroidal worm gear 18, and the first parallel light source 11 is used to emit first parallel light toward the second standard axis 25.

[0044] The second parallel light source 12 is disposed on any end face of the worm gear 19, and the second parallel light source 12 is used to emit second parallel light toward the first standard axis 24.

[0045] It should be noted that the first standard shaft 24 and the second standard shaft 25 are components with known dimensions. Therefore, when it is necessary to align the throats of the toroidal worm 18 and the worm wheel 19, the toroidal worm 18 is first installed on the worm mounting base, and the worm wheel 19 is installed on the worm wheel mounting base. Since the first parallel light source 11 for emitting the first parallel light to the second standard shaft 25 is located on any end face of the toroidal worm 18; and the second parallel light source 12 for emitting the second parallel light to the first standard shaft 24 is located on any end face of the worm wheel 19, refer to... Figure 2(Assuming the first parallel light source 11 is positioned on the upper end face of the toroidal worm 18, the second parallel light source 12 is positioned on the left end face of the worm wheel 19, the length of the toroidal worm 18 is 2L1, the thickness of the worm wheel 19 is 2L2, the radius of the toroidal worm 18 is L3, and the radius of the worm wheel 19 is L4), first move the Z-axis 4 so that the first parallel light emitted by the first parallel light source 11 illuminates the highest point A of the worm wheel 19. Then move the Z-axis 4 downward by a distance of L3-L1 to achieve throat alignment of the toroidal worm 18. Next, move the Y-axis 6 so that the second parallel light emitted by the second parallel light source 12 illuminates point B of the toroidal worm 18. Finally, move the Y-axis 6 to the right of the second parallel axis by a distance of L4-L2 to achieve throat alignment of the worm wheel 19. Then replace the toroidal worm 18 with the first parallel light source 12. The first standard shaft 24 and the worm gear 19 are replaced with the second standard shaft 25. Then, by moving the X-axis moving shaft 5, the first standard shaft 24 and the second standard shaft 25 are about to touch. Then, a feeler gauge with a thickness less than the center distance error requirement is inserted between the first standard shaft 24 and the second standard shaft 25, and the X-axis moving shaft 5 is finely adjusted until the feeler gauge cannot be inserted into the gap between the first standard shaft 24 and the second standard shaft 25. The position of the X-axis moving shaft is set to zero. Since the diameters of the first standard shaft 24 and the second standard shaft 25 are known, after replacing the first standard shaft 24 with the toroidal worm 18 and the second standard shaft 25 with the worm gear 19, the position of the X-axis moving shaft 5 can be further adjusted from the zero position based on the diameters of the first standard shaft 24 and the second standard shaft 25 until the ideal center distance between the toroidal worm 18 and the worm gear 19 is achieved.

[0046] In this embodiment of the invention, the Z-axis guide rail 1 is vertically arranged, and the Z-axis movable shaft 4 is movably arranged on the Z-axis guide rail 1; the driver 7 and the worm gear fixing seat for driving the toroidal worm gear 18 to rotate are both arranged on the Z-axis movable shaft 4; and the first standard shaft 24 or the toroidal worm gear 18 is fixed by the worm gear fixing seat; the X-axis guide rail 2 is horizontally arranged, and the X-axis movable shaft 5 is movably arranged on the X-axis guide rail 2; the Y-axis guide rail 3 is vertically arranged on the X-axis movable shaft 5, and the Y-axis movable shaft 6 is movably arranged on the Y-axis guide rail 3; the loader 9 and the worm gear fixing seat are both arranged on the Y-axis movable shaft 6, and the loader 9 is connected to the worm gear 19 for transmission; and the worm gear 19 or the second standard shaft 25 is fixed by the worm gear fixing seat; the first parallel light source 11 for emitting the first parallel light to the second standard shaft 25 is arranged on any end face of the toroidal worm gear 18; the second parallel light source 12 for emitting the second parallel light to the first standard shaft 24 is arranged on any end face of the worm gear 19. The aforementioned toroidal worm gear transmission detection device allows for the following steps when testing is required: First, the throats of the toroidal worm 18 and worm wheel 19 can be aligned by moving the Z-axis and Y-axis. Then, the toroidal worm 18 is replaced with the first standard shaft 24, and the worm wheel 19 is replaced with the second standard shaft 25. The X-axis is moved, and a feeler gauge with a thickness less than the center distance error requirement is inserted between the first and second standard shafts 24 and 25 until the feeler gauge can no longer be inserted into the gap between the first and second standard shafts 24 and 25. At this point, the position of the X-axis is set to zero. Finally, the first standard shaft 24 is replaced with the toroidal worm 18, and the second standard shaft 25 is replaced with the worm wheel 19. The position of the X-axis is then adjusted by continuing to adjust the position of the X-axis through the zero position, thus completing the precise adjustment of the center distance between the toroidal worm 18 and worm wheel 19.

[0047] Specifically, the worm gear fixing seat includes: upper worm gear support 81 and lower worm gear support 82;

[0048] The upper worm support 81 and the lower worm support 82 are located on the Z-axis moving shaft 4, and the upper worm support 81 and the lower worm support 82 are parallel. The upper worm support 81 is used to fix one end of the first standard shaft 24, and the lower worm support 82 is used to fix the other end of the first standard shaft 24.

[0049] It should be noted that the upper worm support 81 and the lower worm support 82 are set on the Z-axis moving axis 4, and the upper worm support 81 and the lower worm support 82 are parallel. The toroidal worm 18 is set between the upper worm support 81 and the lower worm support 82. The upper worm support 81 and the lower worm support 82 can fix the first standard axis 24. After the toroidal worm 18 replaces the first standard axis 24, the upper worm support 81 and the lower worm support 82 fix the two ends of the toroidal worm 18 to avoid relative displacement when the toroidal worm 18 rotates.

[0050] Specifically, the worm gear mounting base includes: a left worm gear support 101 and a right worm gear support 102;

[0051] The left worm gear support 101 and the right worm gear support 102 are located on the Y-axis moving shaft 6. The left worm gear support 101 and the right worm gear support 102 are parallel.

[0052] It should be noted that the left worm gear support 101 and the right worm gear support 102 are positioned on the Y-axis 6, with the left worm gear support 101 and the right worm gear support 102 parallel to each other. The worm gear 19 is positioned between the left worm gear support 101 and the right worm gear support 102. The left worm gear support 101 and the right worm gear support 102 can fix the second standard shaft 25. After the worm gear 19 replaces the second standard shaft 25, the left worm gear support 101 and the right worm gear support 102 fix the worm gear 19 to prevent relative displacement when the worm gear 19 rotates.

[0053] Furthermore, loader 9 is a magnetic powder loader 9.

[0057] Furthermore, the toroidal worm gear transmission detection device also includes a first displacement sensor 13 for measuring the moving distance of the Z-axis 4.

[0058] It should be noted that by setting a first displacement sensor 13 for measuring the movement distance of the Z-axis 4, it is convenient for the operator to adjust the movement distance of the Z-axis 4 when the throat of the first standard axis 24 is aligned.

[0059] Furthermore, the toroidal worm gear transmission detection device also includes a second displacement sensor 14 for measuring the moving distance of the Y-axis 6.

[0061] Furthermore, the toroidal worm gear transmission detection device also includes a third displacement sensor 15 for measuring the moving distance of the X-axis 5.

[0062] It should be noted that by setting a third displacement sensor 15 for measuring the movement distance of the X-axis 5, the coordinates of the X-axis 5 on the X-axis guide rail 2 can be recorded by the third displacement sensor 15 after the throats of the first and second standard axes 25 are aligned.

[0063] The first displacement sensor 13, the second displacement sensor 14 and the third displacement sensor 15 mentioned above all have the function of recording coordinates and can be set to zero position.

[0064] Furthermore, the toroidal worm gear transmission detection device also includes: an input torque speed sensor 16 and an output torque speed sensor 17;

[0065] The input torque and speed sensor 16 is positioned between the driver 7 and the worm gear mounting base;
