Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of gear testing, in particular to a gear impact fatigue testing device. BACKGROUND

[0002] The generation of impact fatigue is due to the repeated impact load on the gear, which forms periodic stress in the gear material; over time, this stress causes material fatigue, eventually leading to fracture; impact fatigue testing of gears is necessary to ensure that they can withstand impact loads during operation without failure.

[0003] In related technologies, for example, the prior art with publication number CN117848643B provides a gear impact fatigue detection device, which, when detecting the fatigue of the gear, drives the gear to rotate by the first driving device, and the gear extrudes the impact part to make it contract, and the impact part rotates around the first direction by a certain angle; as the gear continues to rotate, the gear loses the extrusion force on the impact part, and the impact part rotates around the second direction, and at the same time, the impact part elongates to impact the tooth surface of the gear to realize the detection of the impact fatigue strength of the gear; when the gear tooth breaks, the broken part does not have force on the impact part, so that the impact part continues to rotate around the second direction and contacts the control switch, and the control switch controls the first driving device to stop rotating; in the detection process, if the gear tooth breaks, it can immediately stop rotating, reducing the error in gear fatigue strength detection and improving the accuracy of the detection result.

[0004] Although the above-mentioned prior art can realize impact testing of the gear by setting the impact part structure, and automatically trigger the device to stop running after the gear tooth breaks, but when the gear contacts the impact part, the impact head will compress the spring inside the shell to slide, resulting in difficulty in adjusting the impact strength during gear testing (especially when a large impact force is required), and it is difficult to adjust the impact strength according to the testing requirements of different gears.

[0079] Principle and advantages of the gear impact fatigue test device:

[0080] Firstly, when the test gear 100 is installed, the test gear 100 is arranged on the outer side of the positioning rod 22, then the positioning block 23 is sleeved on the outer side of the positioning rod 22 through the corresponding flower groove and flower hole, the conical end of the positioning block 23 is used for positioning the test gear 100, the positioning ring 24 is sleeved on the outermost side, the positioning ring 24 is screwedly matched with the positioning rod 22, the positioning ring 24 is used for fixing the positioning block 23 and the test gear 100, and the installation of the test gear 100 is completed;

[0081] Then the second gear 62 is driven to rotate by the clutch motor 61, the corresponding first gear 56 is driven to rotate, the first gear 56 drives the gear ring 51 to rotate, the adjacent two gear rings 51 are driven to rotate through the first gear 56, a plurality of gear rings 51 can rotate together, the corresponding impact part 551 is driven to rotate around the corresponding test gear 100, and the position of the impact part 551 is adjusted.

[0082] The sliding block 531 is slid in the sliding groove 511, the sliding block 531 drives the rotating arm 533 to rotate, the rotating arm 533 drives the sliding rail 534 to move and rotate, the mounting sleeve 55 drives one end of the rotating rod 54 to tightly abut the inner side of the sliding rail 534 under the torsion of the second elastic element 552, so that the angle of the impact part 551 is adjusted, a plurality of rotating arms 533 are connected through the connecting plate 5331, when one of the rotating arms 533 rotates, a plurality of rotating arms 533 are driven to rotate together, so that the impact parts 551 in the plurality of impact assemblies 5 are adjusted together.

[0083] After the position and the angle of the impact part 551 are adjusted, the clamping block 72 is driven to move by the electric push rod 71 at the top and the bottom, the clamping block 72 clamps the connecting plate 5331, and whether the clamping is tight is detected and judged by the pressure sensor.

[0084] When the detection is performed, the rotating speed motor 42 drives the driving part 41 to rotate, adjacent driving parts 41 are connected through the chain 43 and the sprocket 44, the roller 32 is pushed by the driving part 41, the swing arm 31 is rotated, the fixed ring 33 is rotated, the arc-shaped sliding rod 34 and the first elastic element 35 drive the rotating seat 21 to rotate, the rotating seat 21 drives the test gear 100 to rotate, the gear teeth of the test gear 100 impact the impact part 551, the gear teeth of the test gear 100 are impacted and tested, the rotating speed of the test gear 100 is adjusted by adjusting the rotating speed of the rotating speed motor 42, so that the impact of the test gear 100 and the impact part 551 is adjusted, after the test gear 100 and the impact part 551 impact, the impact part 551 prevents the further rotation of the test gear 100, so that the test gear 100 cannot continue to rotate, at this time, the swing arm 31 continues to rotate, the first elastic element 35 is compressed between the arc-shaped block 211 and the fixed ring 33, the arc-shaped sliding rod 34 moves in the inner side of the arc-shaped block 211, at this time, the distance between the detection end of the distance sensor 212 and the end of the arc-shaped sliding rod 34 is detected, when the gear teeth of the test gear 100 are damaged, the angle of the arc-shaped sliding rod 34 and the first elastic element 35 driving the rotating seat 21 to rotate is increased, so that the sliding distance of the arc-shaped sliding rod 34 in the inner side of the arc-shaped block 211 is reduced, the distance detected by the distance sensor 212 is reduced, the distance sensor 212 is arranged away from the center of the hole in the inner side of the arc-shaped block 211, the distance sensor 212 can detect the distance between the detection end and the arc-shaped sliding rod 34, and the test result and the control test process can be displayed through the display control device 121.

[0085] After the impact is completed, the driving member 41 continues to rotate under the driving of the speed regulating motor 42, so that the driving member 41 passes the swing arm 31, and at this time the swing arm 31 is reset under the action of the counterweight 36 after losing the support of the driving member 41, facilitating the next impact and detection.

[0086] The advantages are that the speed of the driving member 41 is adjusted by adjusting the rotating speed of the speed regulating motor 42, the speed of the swing assembly 3 is adjusted, the rotating speed of the test gear 100 is adjusted, the impact strength of the test gear 100 and the impact part 551 is adjusted by adjusting the rotating speed of the test gear 100, and the problem that the impact strength of the gear during testing is inconvenient to adjust and difficult to adjust according to the testing requirements of different gears in the prior art is effectively solved.

[0087] In the gear impact fatigue testing device, the test gear 100 is installed by the positioning block 23 and the positioning ring 24;

[0092] Advantage three: the sliding block 531 slides in the sliding groove 511, the sliding block 531 drives the rotating arm 533 to rotate, the rotating arm 533 drives the sliding rail 534 to move and rotate, and the one end of the rotating rod 54 is always in close contact with the inner side of the sliding rail 534 under the torsion of the second elastic member 552, so that the angle of the impact part 551 is adjusted, and the sliding groove 511 is suitable for test gears 100 of different specifications.
