[0032] Embodiment 1

[0033] In some embodiments, please refer to the attached Figures 1-5 illustration of the specification, a gear meshing and friction and wear performance testing device, including a base 1,

[0034] The upper end of the base 1 is fixedly installed with a conveyor mechanism 2, a meshing test mechanism 3 is installed on the left side of the base 1, a friction and wear test mechanism 4 is installed on the right side of the base 1, and a placing component 6 for placing a standard gear 7 or a test gear 8 is provided at the top of the conveyor mechanism 2, the meshing test mechanism 3 and the friction and wear test mechanism 4; a painting mechanism 5 capable of automatically painting the test gear 8 is provided on the front side of the base 1 for marking the worn positions when the standard gear 7 and the test gear 8 are subjected to friction and wear performance testing.

[0035] The conveying mechanism 2 includes a linear module 21, a connecting plate 22 and a servo motor 23. The linear module 21 is fixedly connected to the upper end of the base 1; the connecting plate 22 is fixedly connected to the moving end of the linear module 21; the servo motor 23 is fixedly connected to the connecting plate 22, and a placing component 6 for placing the test gear 8 is installed at the output end of the servo motor 23.

[0036] In the present utility model, an operator installs a standard gear 7 on the top of each of the meshing test mechanism 3 and the friction and wear test mechanism 4, and installs a test gear 8 on the placing component 6 at the output end of the servo motor 23. The linear module 21 moves the test gear 8 towards the standard gear 7 of the meshing test mechanism 3 until the standard gear 7 meshes with the test gear 8. The servo motor 23 rotates to drive the test gear 8 to rotate, and at the same time, the standard gear 7 drives the test gear 8 to rotate. The meshing test mechanism 3 records parameters such as the number of rotations and rotational speed of the standard gear 7, and compares them with the servo parameters of the servo motor 23 to obtain the meshing data of the standard gear 7 and the test gear 8, realizing the gear meshing test of the test gear 8; after the gear meshing test is completed, the linear module 21 moves the test gear 8 towards the standard gear 7 of the friction and wear test mechanism 4. During the movement, the painting mechanism 5 sprays paint on the tooth surface of the test gear 8, and at the same time, the servo motor 23 rotates to drive the test gear 8 to rotate to achieve uniform painting. When the test gear 8 meshes with the standard gear 7, the servo motor 23 rotates to drive the test gear 8 to rotate, and the standard gear 7 drives the test gear 8 to rotate. After the test gear 8 stops rotating, observe the wear marks on the tooth surface of the test gear 8. If the friction and wear marks on each tooth surface are consistent, it indicates that the test gear 8 has good wear resistance and stable meshing effect.

[0037] In the present utility model, the linear module 21 can be used to control the servo movement of the test gear 8 between the meshing test mechanism 3 and the friction and wear test mechanism 4. It can not only complete the gear meshing test and friction and wear performance test of the test gear 8 at one time, without frequently taking and placing the test gear 8 on different test equipment, which is convenient for operation, reduces the standby time of the equipment, and effectively improves the test efficiency, but also can be applicable to test gears 8 of different sizes; the painting mechanism 5 can automatically spray paint on the test gear 8 without manual spraying on the test gear 8, which not only makes the painting more uniform and the operation more convenient, but also avoids the paint escaping during spraying from being inhaled by the operator and affecting health, and at the same time facilitates the test operation of the gear friction and wear performance, further improving the detection efficiency.

[0038] The placing component 6 includes a fixing block 61 and a transmission rod 62. The upper end of the fixing block 61 is fixedly connected with a transmission rod 62 for placing the standard gear 7 or the test gear 8. The standard gear 7 or the test gear 8 is inserted into the transmission rod 62 through a key, so that the standard gear 7 or the test gear 8 rotates synchronously with the transmission rod 62.

[0039] The output end of the servo motor 23 on the conveying mechanism 2 is inserted into the fixed block 61, so that the output end of the servo motor 23 and the fixed block 61 rotate synchronously.

The encoder 31 is fixedly connected to the left side of the base 1; the first vertical frame 32 is fixedly connected to the left side of the base 1; the first connecting rod 33 is rotatably connected to the first vertical frame 32 through a bearing; the lower end of the first connecting rod 33 passes through the first vertical frame 32 and is connected to the encoder 31, and the upper end of the first connecting rod 33 is inserted into the fixed block 61, so that the first connecting rod 33 and the fixed block 61 rotate synchronously.

[0041] In the present utility model, the linear module 21 moves the test gear 8 towards the standard gear 7 of the meshing test mechanism 3 until the standard gear 7 meshes with the test gear 8. The servo motor 23 rotates, the transmission rod 62 on the conveying mechanism 2 drives the test gear 8 to rotate, the test gear 8 drives the standard gear 7 to rotate, and the rotation of the standard gear 7 drives the transmission rod 62 on the meshing test mechanism 3 to rotate synchronously, so that the first connecting rod 33 rotates synchronously. The encoder 31 records parameters such as the number of rotations and rotational speed of the standard gear 7, and compares them with the servo parameters of the servo motor 23 to obtain the meshing data of the standard gear 7 and the test gear 8, realizing the gear meshing test of the test gear 8.

[0042] The painting mechanism 5 includes a moving component 51, a fixed frame 52, a paint can 53, a push-type pump head 54, a pressing component 55 for pressing the push-type pump head 54, and a locking component 56. The moving component 51 is installed on the base 1; a fixed frame 52 for placing the paint can 53 is fixedly installed on the upper side of the moving component 51; the upper end of the paint can 53 is provided with a push-type pump head 54; the pressing component 55 is connected to the upper side of the fixed frame 52; the locking component 56 is provided on the pressing component 55.

[0043] The moving component 51 includes a vertical plate 511, a screw 512 and a slider 513. The vertical plate 511 is fixedly connected to the front side of the base 1; the screw 512 is threadedly connected to the vertical plate 511 through a threaded sleeve; the screw 512 passes through the vertical plate 511 and is rotatably connected to the slider 513 through a bearing. The slider 513 is in sliding fit with the base 1, and the upper end of the slider 513 is fixedly connected to a fixed frame 52 for placing the paint can 53.

[0044] The pressing component 55 includes a cross bar 551 and a cylinder 552 for pressing the push-type pump head 54. One end of the cross bar 551 is rotatably connected to the top of the fixed frame 52; the other end of the cross bar 551 is fixedly connected to the cylinder 552.

[0045] The locking assembly 56 includes a bolt 561, a fixing rod 562, and a small hole 563 for inserting the bolt 561. The fixing rod 562 is fixedly connected to the upper side of the fixing frame 52; small holes 563 that cooperate with each other are provided on the cross bar 551 and the fixing rod 562, and the bolt 561 is inserted into the cross bar 551 and the fixing rod 562 through the small hole 563.

[0046] In the present utility model, after the gear meshing test is completed, the linear module 21 moves the test gear 8 towards the standard gear 7 of the friction and wear test mechanism 4. When moving past the painting mechanism 5, the servo motor 23 starts to rotate to drive the test gear 8 to rotate. At the same time, the output end of the air cylinder 552 presses down on the pressing pump head 54 to achieve uniform painting. After the painting is completed, the servo motor 23 stops rotating, and at the same time, the air cylinder 552 resets to stop painting. Since the rotation speed of the servo motor 23 is uniform and the pressure of the air cylinder 552 pressing on the nozzle of the paint can 53 remains unchanged, the painting of the test gear 8 is uniform, convenient and fast; when replacing the test gear 8 with different diameters, rotate the screw rod 512. Under the limiting action of the vertical plate 511, the screw rod 512 drives the slider 513 to move, so that the distance between the pressing pump head 54 and the test gear 8 is the most effective painting distance, ensuring that the painting effect remains the same after replacing the test gear 8 with different diameters; when the paint can 53 needs to be replaced after it is used up, pull out the bolt 561, release the cross bar 551 and rotate the cross bar 551 so that the cross bar 551 is misaligned with the paint can 53 to facilitate the replacement of the paint can 53. After replacing the paint can 53, rotate the cross bar 551 so that the small hole 563 on the cross bar 551 is aligned with the small hole 563 on the fixing rod 562, and insert the bolt 561 into the aligned small hole 563 to lock the cross bar 551, avoiding the displacement of the cross bar 551 caused by vibration during the operation.

[0047] The friction and wear test mechanism 4 includes a second vertical frame 41 and a second connecting rod 42. The upper end of the base 1 is fixedly connected with the second vertical frame 41; the second connecting rod 42 is rotatably connected to the second vertical frame 41 through a bearing; the lower end of the second connecting rod 42 passes through the second vertical frame 41 and is rotatably connected to the base 1 through a bearing, and the upper end of the second connecting rod 42 is inserted into the fixing block 61.

[0048] In the present utility model, after the test gear 8 is uniformly painted, the linear module 21 moves the test gear 8 towards the standard gear 7 of the friction and wear test mechanism 4. Until the standard gear 7 meshes with the test gear 8, the servo motor 23 starts to rotate to drive the test gear 8 to rotate. The test gear 8 drives the standard gear 7 to rotate. After the test gear 8 stops rotating, observe the wear marks on the tooth surface of the test gear 8. If the friction and wear marks on each tooth surface are consistent, it indicates that the test gear 8 has good wear resistance and a stable meshing effect, and there is no need to move the test gear 8 to other test devices, which is convenient and fast.

[0049] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
