Description

Technical Field

[0001] This utility model relates to the field of testing equipment technology, specifically to a device for testing the lifespan of a sun gear. Background Technology

[0002] A corrugated board production line is a general term for the production line used to produce corrugated paper. During the production of corrugated paper, the corrugated paper needs to be conveyed. The conveying of the corrugated paper uses a sun gear. The sun gear needs to be tested after leaving the factory or before use to ensure that the service life of the sun gear is within the specified threshold range.

[0003] To facilitate life testing of sun gears in corrugated sheet production lines, existing technologies have made numerous improvements to sun gear life testing devices. For example, patent publication number CN201611326U discloses a device for testing the life of sun gears in corrugated sheet production lines. This device includes a frame, a servo motor, a motor support, an upper pressure roller shaft, a lower pressure roller, a roller shaft support, and a protective cover. The upper and lower pressure roller shafts are mounted on the roller shaft support. The lower pressure roller is mounted on the lower pressure roller shaft via bearings. The servo motor is connected to a reducer, and the reducer's output shaft is connected to the upper pressure roller shaft. Friction strips are arranged along the axial direction of the lower pressure roller. The sun gear to be tested is fixedly connected to the upper pressure roller shaft and pressed tightly against the lower pressure roller. The protective cover is located on the outer periphery of the servo motor, the upper pressure roller shaft, and the lower pressure roller. This invention uses a servo motor to drive the sun gear to be tested, causing it to press tightly against the pressure roller with friction strips, simulating the actual working conditions of the sun gear. This allows for the testing of the sun gear's lifespan, providing a reference for actual production and preventing production accidents.

[0004] The aforementioned patents have significant beneficial effects, but in practical application, they still have the following shortcomings:

[0005] The aforementioned patent document tests the lifespan of the corrugated sheet sun gear by rubbing it against a friction strip, with the metal strip being a metal product. However, in reality, the corrugated sheet sun gear transmits heat through the corrugated paper. The corrugated paper has relatively low heat content, is constantly in a transmission state, and has a low thermal conductivity. The metal strip in the patent document has a high thermal conductivity, causing the sun gear to continuously heat up rapidly. In contrast, in actual corrugated sheets, the heat generated during sun gear rotation is relatively low due to the low thermal conductivity of the corrugated paper, and sustained temperature increases are rare. Cracks are less common; instead, deformation and elliptical or outer circumferential wear are more frequent. This can lead to several sun gears rotating at different speeds, requiring replacement. Therefore, the lifespan test data for the corrugated sheet sun gear in the aforementioned patent document is inaccurate. Thus, there is an urgent need in the art to improve the device used for testing the lifespan of corrugated sheet sun gears to overcome the shortcomings of the existing technology. Utility Model Content

[0006] To address the shortcomings of existing technologies, this invention provides a device for testing the lifespan of a sun gear in a corrugated wire system, thereby improving the accuracy of lifespan test data for the sun gear itself.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a device for testing the life of a sun gear in a corrugated sheet, comprising a test platform, an annular test belt forming a closed loop, a first drive motor for driving the annular test belt, and an inverted U-shaped support frame, wherein a transverse support seat is provided inside the support frame, a first fixing plate is fixedly installed on the lower surface of the support seat and a second fixing plate is slidably connected thereto, a plurality of rotating shafts are rotatably connected to one side of the first fixing plate, the sun gear body to be tested is sleeved on the side of the rotating shaft, a limiting pin adapted to the sun gear body is fixedly connected to the side of the rotating shaft, a plurality of insertion interfaces adapted to the rotating shafts are provided on the second fixing plate, and a first drive unit for driving the second fixing plate to move along the support seat is provided on the support seat.

[0010] Preferably, a first support frame is fixedly installed on the upper surface of the test platform and a second support frame is slidably connected thereto. A drive roller adapted to an annular test belt is rotatably connected to one side of the second support frame. One end of the drive roller is fixedly installed to the output end of a first drive motor, and the end of the drive roller away from the first support frame is inserted into the second support frame. The test platform is provided with a second drive unit for driving the first support frame to move.

[0011] Preferably, the second drive unit includes a third drive motor fixedly installed on one side of the test bench, and second sliding blocks are fixedly installed at both ends of the second support frame. A second sliding groove adapted to the second sliding block is opened on the upper surface of the test bench. A second lead screw extending to the outside is rotatably connected in the second sliding groove. The second lead screw passes through the second sliding block and is threadedly connected to the second sliding block. A transmission wheel is fixedly installed on the side of the outer end of the second lead screw and the side of the output end of the third drive motor. A transmission belt for transmission is sleeved on the sides of two adjacent transmission wheels.

[0012] Preferably, both the first fixing plate and the second fixing plate have a plurality of rotating rings rotatably connected to their opposing sides, and the rotating rings are located on the side of the rotating shaft.

[0013] To address the shortcomings of existing technologies, this invention provides a device for testing the lifespan of a sun gear in a corrugated wire system, overcoming these deficiencies. The beneficial effects of this invention are as follows:

[0014] 1. In this utility model, several sun gear bodies are sleeved on the side of a rotating shaft. The first drive unit is activated to drive the second fixed plate closer to the first fixed plate. The telescopic device is activated to control the several sun gear bodies to abut against the surface of the annular test belt. The telescopic device is used to control the pressing force between the several sun gear bodies and the surface of the annular test belt according to the actual situation. The output end of the first drive motor drives the annular test belt to rotate.

[0016] 3. In this utility model, when the first drive motor is started, the first drive motor drives the second support frame to move along the second sliding groove. The second support frame drives the drive roller to disengage from the first support frame, so that the annular test belt can be removed from the sides of the two drive rollers and a new annular test belt can be fitted onto the sides of the two drive rollers. This makes it convenient for the test personnel to install or replace the annular test belt later, thereby improving the efficiency of testing the sun gear body.

The support frame 4 contains a transverse support seat 5. A first fixing plate 6 is fixedly mounted on the lower surface of the support seat 5, and a second fixing plate 7 is slidably connected thereto. Several rotating shafts 8 are rotatably connected to one side of the first fixing plate 6. A sun gear body 10 to be tested is fitted onto the side of each rotating shaft 8. A limiting pin 9 adapted to the sun gear body 10 is fixedly connected to the side of each rotating shaft 8. Several insertion interfaces 11 adapted to the rotating shafts 8 are provided on the second fixing plate 7. A first drive unit 12 for driving the second fixing plate 7 to move along the support seat 5 is provided on the support frame 4. A telescopic device 13 is fixedly mounted on the support frame 4.

Several rotating rings 30 are rotatably connected to the opposing sides of both the first fixing plate 6 and the second fixing plate 7. The rotating rings 30 are located on the sides of the rotating shafts 8.

[0030] Specific implementation method in this embodiment: When testing the sun gear body 10, the first drive unit 12 drives the second fixing plate 7 away from the first fixing plate 6. The tester places several sun gear bodies 10 on the side of the rotating shaft 8, and the limiting pin 9 engages with the pin groove inside the sun gear body 10. The first drive unit 12 is started again to drive the second fixing plate 7 closer to the first fixing plate 6. One end of the rotating shaft 8 is inserted into the insertion interface 11. The two rotating rings 30 are located on both sides of the sun gear body 10. The telescopic device 13 is activated to control several sun gear bodies 10 to abut against the surface of the annular test belt 2. The first drive motor 3 is started. The output end of the first drive motor 3 drives the annular test belt 2 to drive, thereby simultaneously driving several... Several sun gear bodies 10 rotate, and the clamping force between several sun gear bodies 10 and the surface of the annular test belt 2 can be controlled by the telescopic device 13 according to the actual situation. At the same speed, when a sun gear body 10 rotates unevenly or does not rotate, it means that the outer circle of the sun gear body 10 has been deformed or severely worn. Test several sun gear bodies 10 and record the data. Remove the maximum and minimum values ​​and take the average of the remaining data to obtain the average service life of the sun gear body 10, which improves the accuracy of the life test data of the sun gear body 10. At the same time, when using the sun gear body 10, the usage time should be less than the average data to ensure that the bearing line is not damaged by the sun gear body 10 and caused further damage.
