Description

Technical Field

[0001] This utility model relates to the field of test bench technology, and more specifically, to a precision reducer test bench. Background Technology

[0002] Precision reducers are core transmission components in high-end equipment such as robots, aerospace, and precision machine tools. Their transmission accuracy, load capacity, and lifespan directly determine the overall operating quality of the machine. Therefore, they must undergo professional testing before leaving the factory and during operation and maintenance to ensure that their performance meets the standards.

[0003] In existing technologies, fatigue life of precision reducers is a core performance indicator. During testing, it is necessary to stably simulate load conditions. Traditional inertia disks are not securely fixed, which can easily lead to deviations in test data and affect the accuracy of life determination. Fatigue life tests require the motor to run continuously for a long time, which can easily generate a lot of heat. Overheating can lead to a decline in motor performance, which not only affects the continuity of testing but also shortens the service life of the motor. Utility Model Content

[0004] In view of the problems existing in the prior art, this utility model provides a precision reducer test bench to solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a precision reducer test bench, including a support platform, a support base and a drive motor on the support platform, an installation groove on the support base, a support pad inside the installation groove, ventilation holes corresponding to the support pad and the installation groove, an air inlet box on the support base, a connecting fan on the air inlet box, a filter layer on one side of the connecting fan, a limiting frame on one side of the filter layer, an air inlet duct on the limiting frame, a fixing ring on the support base, a rubber pad at the bottom of the fixing ring, a fixing rod and a fixing plate on the motor shaft of the drive motor, and an inertia disk on the fixing plate.

[0006] The present invention is further configured such that the filter layer includes a filter core layer, and an arc-shaped grid plate is provided on one side of the filter core layer to facilitate support of the filter core layer.

[0007] The present invention is further configured such that mounting plates are provided at both ends of the filter layer, teeth are provided inside the air inlet box, and grooves that cooperate with the teeth are provided on the mounting plate to facilitate the installation of the filter layer.

[0008] The present invention is further configured such that a limiting bolt is provided between the limiting frame and the air inlet box, which facilitates the disassembly of the limiting frame and the installation and cleaning of the filter layer.

[0009] The present invention is further configured such that the support pad has multiple support protrusions in the circumferential direction, which facilitates the support of the drive motor and creates a certain distance between the brushless motor and the support pad, which facilitates ventilation and heat dissipation.

[0010] The present invention is further configured such that a fixing plate is provided on the fixing rod, the fixing plate is provided with a notch, and a locking block is provided around the fixing plate. The fixing plate is engaged with the inertia disk through the locking block, thereby connecting the fixing plate and the inertia disk.

[0011] The present invention is further configured such that the fixing rod is provided with a fastening plate, the fastening plate is provided with an insertion rod, and the fixing plate and the fixing plate are provided with insertion holes that cooperate with the insertion rod, so as to facilitate the connection of the fixing plate and the fixing rod through the fastening plate.

[0012] The present invention is further provided with a fixing screw rotatably mounted on the fixing rod, and the fixing screw is threadedly rotatably connected to the fastening disc, which facilitates the movement of the fastening disc. Beneficial effects

[0013] Compared with the prior art, the present invention provides a precision reducer test bench, which has the following advantages: 1. The inertia disk is positioned by being snapped into the fixed disk by a locking block. Rotating the fixing screw drives the fastening disk to move, so that the insertion rod is inserted into the insertion hole for double fixation. The drive motor drives the inertia disk to rotate stably. After being connected to the reducer, it can accurately simulate the load and ensure the reliability of fatigue life test data.

[0014] 2. The drive motor is placed on a support pad with supporting protrusions. The fixing ring and rubber pad are used to fix the position. The support pad is made of elastic material to buffer vibration. The vibration of the motor is greatly reduced when it runs, the test system runs stably, and the test accuracy of various parameters is improved.

[0015] 3. The filter layer is positioned by teeth and grooves, and the limiting bracket helps to fix it to prevent displacement; when the ventilation fan is started, the airflow is filtered and blown to the motor through the ventilation holes. The filtered airflow improves the motor's heat dissipation efficiency, avoids overheating, ensures long-term continuous testing, and extends the motor's life. Attached Figure Description

[0021] Please see Figures 1-5A precision reducer test bench includes a support platform 1, a support base 2 and a drive motor 3 on the support platform 1, a mounting groove 4 on the support base 2, a support pad 5 inside the mounting groove 4, ventilation holes 6 corresponding to the support pad 5 and the mounting groove 4, an air inlet box 7 on the support base 2, a connecting fan 8 on the air inlet box 7, a filter layer 9 on one side of the connecting fan 8, a limiting frame 10 on one side of the filter layer 9, an air inlet duct 11 on the limiting frame 10, a fixing ring 12 on the support base 2, and a rubber pad 13 at the bottom of the fixing ring 12. The drive motor 3... The machine shaft is provided with a fixed rod 14 and a fixed plate 15. The fixed plate 15 is provided with an inertia disk 16. The fixed rod 14 is provided with a fixed disk 24. The fixed disk 24 is provided with a notch 25. The fixed disk 24 is provided with a locking block 26 around its circumference. The fixed disk 24 is engaged with the inertia disk 16 through the locking block 26. The fixed rod 14 is provided with a fastening disk 27. The fastening disk 27 is provided with an insertion rod 28. The fixed disk 24 and the fixed plate 15 are provided with an insertion hole 29 that mates with the insertion rod 28. The fixed rod 14 is rotatably provided with a fixing screw 30. The fixing screw 30 is threadedly rotatably connected to the fastening disk 27.

[0022] In this embodiment, during use, the inertia disk 16 is passed through the fastening disk 27 and fitted onto the fixing plate 15 and the fixing plate 16. It passes through the fixing rod 14 through the notch 25. The fixing plate 24 and the inertia disk 16 are locked together by the locking block 26. Then, the fixing screw 30 is rotated, and the fixing screw 30 and the fastening disk 27 rotate relative to each other, thereby driving the fastening disk 27 to move. This allows the insertion rod 28 to be inserted into the insertion hole 29 of the fixing plate 24, thereby fixing the relative position of the fixing plate 15 and the fixing plate 24. The motor shaft of the drive motor 3 drives the fixing plate 15 and the fixing rod 14 to rotate, thereby driving the fastening disk 27 and the fixing plate 24 to rotate. The inertia disk 16 is connected to the reducer using existing technology, which facilitates the measurement of the fatigue life of the reducer.

[0023] Please see Figures 1-3 As a further implementation of the overall equipment: the filter layer 9 includes a filter core layer 17, an arc-shaped grid plate 18 is provided on one side of the filter core layer 17, mounting plates 19 are provided at both ends of the filter layer 9, teeth 20 are provided inside the air inlet box 7, and tooth grooves 21 that cooperate with the teeth 20 are provided on the mounting plate 19. A limiting bolt 22 is provided between the limiting frame 10 and the air inlet box 7, and multiple supporting protrusions 23 are provided circumferentially on the support pad 5.

[0024] More specifically, during use, the drive motor 3 is placed on the support pad 5 of the support base 2 and elastically supported by the support protrusion 23. The position of the drive motor 3 is fixed by the fixing ring 12. The vibration of the drive motor 3 during operation is buffered by the cooperation of the support pad 5 and the rubber pad 13. The support pad 5 is made of nitrile rubber with Shore hardness, and the filter layer 9 is made of HEPA filter material. The filter layer 9 is driven to extend the mounting plate 19 into the air inlet box 7. The position of the mounting plate 19 and the filter layer 9 is limited by the cooperation of the teeth 20 and the grooves 21. The limit bracket 10 supports one side of the filter layer 9 to prevent the filter layer 9 from shifting or deforming. Then, the connecting fan 8 is started, and the airflow enters the air inlet box 7 through the air inlet duct 11. After being filtered by the filter core layer 17, it enters the interior of the support base 2 and blows the air towards the drive motor 3 through the ventilation hole 6, which increases the air circulation rate at the drive motor 3 and facilitates the dissipation of heat generated by the drive motor 3 during operation.

[0025] In summary, during use or operation of the overall equipment: In use, the inertia disk 16 passes through the fastening disk 27 and is fitted onto the fixing plate 15. It then passes through the notch 25 and the fixing rod 14. The locking block 26 engages and fixes the fixing plate 24 with the inertia disk 16. Subsequently, rotating the fixing screw 30 causes relative threaded rotation between the fixing screw 30 and the fastening disk 27, thereby moving the fastening disk 27. This allows the insertion rod 28 to be inserted into the insertion hole 29 of the fixing plate 24, thus fixing the relative position of the fixing plate 15 and the fixing plate 24. The motor shaft of the drive motor 3 drives the fixing plate 15 and the fixing rod 14 to rotate, which in turn drives the fastening disk 27 and the fixing plate 24 to rotate. The inertia disk 16 is connected to the reducer using existing technology, facilitating the measurement of the reducer's fatigue life.

[0026] In use, the drive motor 3 is placed on the support pad 5 of the support base 2 and elastically supported by the support protrusion 23. The position of the drive motor 3 is fixed by the fixing ring 12. The vibration of the drive motor 3 during operation is buffered by the cooperation of the support pad 5 and the rubber pad 13. The support pad 5 is made of nitrile rubber with Shore hardness, and the filter layer 9 is made of HEPA filter material. The filter layer 9 is inserted into the air inlet box 7 along with the mounting plate 19. The position of the mounting plate 19 and the filter layer 9 is limited by the cooperation of the teeth 20 and the grooves 21. The limit bracket 10 supports one side of the filter layer 9 to prevent the filter layer 9 from shifting or deforming. Then, the connecting fan 8 is started, and the airflow enters the air inlet box 7 through the air inlet duct 11. After being filtered by the filter core layer 17, it enters the interior of the support base 2 and is blown towards the drive motor 3 through the ventilation hole 6, which improves the air circulation rate at the drive motor 3 and facilitates the dissipation of heat generated by the drive motor 3 during operation.
