DETAILED DESCRIPTION

[0029] In order to make the content of the present invention more clearly understood, the present invention is further described in detail below based on specific implementation methods and in conjunction with the accompanying drawings.

[0030] Figure 1A schematic structural diagram of a servo-controlled bevel gear engagement detection device provided in an embodiment of the present application. The device includes a base 100, a detection platform 200, a first bevel gear placement seat 300, a transmission platform 500, a second bevel gear placement seat 600, and a vibration detection device 700. Among them, the first bevel gear placement seat 300 is set on the detection platform 200, and the second bevel gear placement seat 600 is set on the transmission platform 500. When bevel gears are placed on both the first bevel gear placement seat 300 and the second bevel gear placement seat 600, the two bevel gears can be engaged by moving the transmission platform 500. At this time, the bevel gears are driven to rotate by the transmission platform 500, and the vibration noise of the two bevel gears can be detected by the vibration detection device 700.

[0031] Specifically, the test platform 200 is fixedly mounted on the base 100. The first bevel gear placement seat 300 is fixedly mounted on the test platform 200. Figure 1 The first bevel gear placement seat 300 includes a first mounting flange 310 fixedly mounted on the test bench 200 by bolts. A limiting column 320 is fixedly mounted on the first mounting flange 310, and the axis of the limiting column 320 coincides with the axis of the first mounting flange 310, and both extend in the vertical direction. A pad column 330 and a magnetic gasket 340 are coaxially sleeved on the outer side of the limiting column 320. The pad column 330 is hollow cylindrical, and the inner diameter of the pad column 330 is equal to the cross-sectional diameter of the limiting column 320, so that an interference fit is formed between the pad column 330 and the limiting column 320. The magnetic gasket 340 is magnetically adsorbed on the upper end of the pad column 330. The inner diameter of the magnetic gasket 340 is also equal to the cross-sectional diameter of the limiting column 320, so that an interference fit is also formed between the magnetic gasket 340 and the limiting column 320.

[0032] It should be noted that the height of the limiting post 320 is greater than the sum of the height of the support post 330 and the thickness of the magnetic washer 340. Therefore, the upper end surface of the limiting post 320 is higher than the upper end surface of the magnetic washer 340. When the planetary bevel gear is placed on the first bevel gear placement seat 300, the limiting post 320 is inserted into the through hole in the center of the planetary bevel gear, and the axis of the planetary bevel gear coincides with the axis of the limiting post 320. The lower end surface of the planetary bevel gear is magnetically connected to the magnetic washer 340.

[0033] Preferably, the lower end surface of the planetary bevel gear placed on the first bevel gear placement seat 300 is a convex spherical surface. Correspondingly, the upper end surface of the magnetic pad 340 is a concave spherical surface that matches the lower end surface of the planetary bevel gear. When the planetary bevel gear is placed on the first bevel gear placement seat 300, the lower end surface of the planetary bevel gear and the upper end surface of the magnetic pad 340 are in contact and magnetically connected, ensuring the stability of the planetary bevel gear on the first bevel gear placement seat 300.

[0034] A movable guide rail 400 is fixedly provided on the base 100. Figure 1The movable guide rail 400 extends along the length of the base 100, and the detection platform 200 is located at one end of the length of the base 100. The transmission platform 500 is slidably disposed on the movable guide rail 400. When the transmission platform 500 moves along the movable guide rail 400, the transmission platform 500 will move closer to or away from the detection platform 200.

[0035] The second bevel gear placement seat 600 is fixedly mounted on the transmission platform 500. Figure 1 The second bevel gear placement seat 600 includes a second mounting flange 610 and a connecting column 620 fixedly mounted on the second mounting flange 610. The axis of the connecting column 620 coincides with the axis of the second mounting flange 610, and both extend in the horizontal direction, that is, perpendicular to the axis of the first mounting flange 310. When the half-shaft bevel gear is placed on the second bevel gear placement seat 600, the connecting column 620 is inserted into the through hole in the middle of the half-shaft bevel gear, and the axis of the half-shaft bevel gear coincides with the axis of the connecting column 620. The cross-sectional diameter of the connecting column 620 is equal to the diameter of the through hole in the middle of the half-shaft bevel gear, so that an interference fit is formed between the half-shaft bevel gear and the connecting column 620.

[0036] It should be noted that the axis of the first mounting flange 310 and the axis of the second mounting flange 610 are located in the same vertical plane. When bevel gears are placed on both the first bevel gear placement seat 300 and the second bevel gear placement seat 600, the transmission platform 500 moves along the movable guide rail 400 to allow the two bevel gears to mesh with each other.

[0037] A rotary drive device is provided on the transmission platform 500 to drive the second bevel gear receiving seat 600 for rotation. This rotary drive device includes a servo motor 510 fixedly mounted on the transmission platform 500. The rotational axis of the servo motor 510 is fixedly connected to the second mounting flange 610, and the axis of the second mounting flange 610 coincides with the axis of the servo motor 510's rotational axis. When the servo motor 510 is in operation, it drives the second mounting flange 610 to rotate about its own axis. Simultaneously, because the half-shaft bevel gears mounted on the second bevel gear receiving seat 600 have an interference fit with the connecting post 620, the servo motor 510 drives the half-shaft bevel gears to rotate synchronously.

[0038] Preferably, a connecting flange 520 is fixedly mounted on the end of the rotating shaft of the servo motor 510. The axis of the connecting flange 520 coincides with the axis of the rotating shaft of the servo motor 510. A second mounting flange 610 is removably mounted to the connecting flange 520 via bolts. Furthermore, multiple second mounting flanges 610 are provided, each with a connecting column 620 having a different cross-sectional diameter. The cross-sectional diameters of the connecting columns 620 in these multiple second mounting flanges 610 are adapted to the diameters of the central through holes of different sized axle bevel gears. This allows the detection device to be adapted to axle bevel gears of varying sizes.

[0039] A vibration detection device 700 is fixedly mounted on the base 100 to detect vibrations during bevel gear meshing. When the two bevel gears mounted on the first bevel gear holder 300 and the second bevel gear holder 600 mesh with each other, the servo motor 510 is activated to simulate bevel gear transmission. The vibration detection device 700 then detects vibration noise from the bevel gears on the component platform.

[0040] Therefore, the technical solution of the present application realizes the detection of bevel gear meshing by setting a first bevel gear placement seat 300 and a second bevel gear placement seat 600 to place two bevel gears to be tested respectively, and realizes the meshing rotation of the two bevel gears through the transmission platform 500, detects the vibration noise, transmission accuracy, etc. of the two bevel gears, and realizes the detection of bevel gear meshing. It not only has a simple structure but also has high detection accuracy.

[0041] In addition to the above embodiments, the present invention may also have other implementation methods; any technical solutions formed by equivalent replacement or equivalent transformation fall within the protection scope required by the present invention.
