Abstract
Description
Technical Field
[0001] This application relates to the field of mechanical transmission equipment testing technology, and in particular to a device for testing the no-load stability of a speed reducer. Background Technology
[0002] As a key component in mechanical transmission systems, speed reducers are widely used in CNC machine tools and industrial robots due to their advantages such as compact structure, high transmission efficiency, and smooth operation. During the speed reducer manufacturing process, performing no-load testing is a crucial step in ensuring the stable operation of the speed reducer.
[0003] One related method for testing a reducer under no-load conditions is manual testing. When it is necessary to test the operating status of the reducer under no-load conditions, the operator manually rotates the input shaft of the reducer. After the input shaft rotates, the operator can observe whether the reducer exhibits any abnormal phenomena such as jamming, abnormal noise, or vibration.
[0004] When testing a reducer using the above method, the reducer relies on manual application of external force to drive the input shaft to rotate during the testing process. However, it is difficult to ensure that the input shaft rotates continuously and at a uniform speed by manually applying external force, which results in the test results failing to accurately reflect the actual operating state of the reducer and thus affecting the accuracy of the test results. Summary of the Invention
[0005] To improve the accuracy of no-load testing of speed reducers, this application provides a speed reducer no-load stability testing device.
[0006] This application provides a device for detecting the no-load stability of a speed reducer, which adopts the following technical solution: A device for detecting the no-load stability of a speed reducer, comprising: A workbench, which is fixedly installed on the ground, and has multiple fixed gaps horizontally arranged on the workbench; A fixing component is fixedly mounted on the workbench, which can fix the reducer to be tested on the workbench; The detection component is rotatably mounted on the ground and is arranged parallel to the fixing component. The detection component can perform no-load testing on the reducer. A positioning component is fixedly mounted on the worktable and is arranged parallel to the fixing component. The positioning component ensures that the test piece remains in contact with the reducer throughout the testing process.
[0007] By adopting the above technical solution, when a no-load test of the reducer is required, the reducer to be tested is placed on a fixed component, which then secures the reducer to the worktable. After the reducer is fixed on the worktable, the testing component is fitted onto the input shaft of the reducer. The testing component is then activated, causing the input shaft of the reducer to rotate. This rotation allows for the testing of the reducer's operating condition under no-load conditions. During the rotation of the testing component, a positioning component is positioned to abut against the end of the testing component furthest from the reducer. This contact restricts the radial displacement of the testing component, ensuring it does not detach from the reducer. This method of testing the reducer's no-load operating state avoids errors in the test results caused by discontinuous or uneven rotation of the input shaft during the testing process, thereby improving the accuracy of no-load testing of the reducer.
[0008] Optionally, the fastener includes: A fixing plate is fixedly mounted on the workbench. The fixing plate is fixedly provided with detection holes and multiple mounting holes are provided at intervals on the fixing plate. Mounting bolts are provided, and each mounting bolt corresponds to one of the mounting holes; Two mounting plates are symmetrically arranged along the fixing plate, and the mounting plates are fixedly mounted on the fixing plate by mounting bolts. The snap-fit bolts are provided at intervals along the fixed gap, and each snap-fit bolt is fixedly disposed within the fixed gap; The snap-fit plate is provided in multiple ways. Each snap-fit plate is fixed to the worktable by two snap-fit bolts, and the two ends of the fixing plate are located between the snap-fit plate and the worktable.
[0009] By adopting the above technical solution, when a reducer needs to be tested, the clamping plate is placed on the worktable, positioned on the fixing plate, and then fixed to the worktable using clamping bolts. After the fixing plate is fixed, the reducer is placed in the test hole, and the mounting plate is fixed to the fixing plate using mounting bolts, clamping the outer wall of the reducer. Once the mounting plate is clamped to the outer wall of the reducer, the test piece can be placed on the input shaft of the reducer and activated. Activation of the test piece drives the input shaft of the reducer to rotate, allowing for no-load testing of the reducer. This method of no-load testing avoids deviations in test results caused by reducer shaking during the testing process, thus improving the accuracy of no-load testing of the reducer.
[0010] Optionally, the detection element includes: A detection plate, which is fixedly installed on the ground; An electric motor, which is fixedly mounted on the detection plate; A drive wheel is rotatably mounted on the detection plate and is fixedly connected to the output shaft of the motor. A fitting groove is vertically provided on the drive wheel. A spline is fitted onto the input end of the reducer to be tested. A mating groove is vertically provided on the spline, and the mating groove has the same specifications as the fitting groove. A belt, one end of which is wound around the fitting groove and the other end of which is wound around the mating groove.
[0011] By adopting the above technical solution, after the reducer is fixed on the mounting plate, the spline is sleeved on the reducer's input shaft. Starting the motor causes the drive wheel to rotate, which in turn drives the belt, which in turn drives the spline, which in turn drives the reducer's input shaft. Once the input shaft rotates, the reducer can be tested under no-load conditions. This method of no-load testing avoids deviations in test results caused by the input shaft not rotating continuously and uniformly during the testing process, thus improving the accuracy of no-load testing of the reducer.
[0012] Optionally, the positioning element includes: A positioning plate is fixedly mounted on the workbench, and the positioning plate is arranged parallel to the fixed plate. Two positioning holes are provided at intervals at the bottom end of the positioning plate. Two positioning bolts are spaced apart along the fixed gap, and the positioning plate is fixedly mounted on the worktable by the positioning bolts. A connecting plate, which is fixedly mounted on the positioning plate; A spherical shell is fixedly mounted on the connecting plate, and a plurality of rolling grooves are spaced apart inside the spherical shell; A star-shaped sleeve is rotatably disposed inside the spherical shell, and a plurality of movable grooves are spaced apart on the surface of the star-shaped sleeve; The ball bearings are arranged in a one-to-one correspondence with the rolling groove and the moving groove, and each ball bearing is embedded between the moving groove and the rolling groove; A positioning rod, one end of which is fixedly connected to the end of the star-shaped sleeve away from the spherical shell, and the other end of which abuts against the spline shaft center.
[0013] By adopting the above technical solution, after the spline is sleeved on the output shaft of the reducer and the spline begins to rotate, the positioning rod is rotated. The rotation of the positioning rod causes the star-shaped sleeve to rotate synchronously. The rotation of the star-shaped sleeve drives the balls to roll in the rolling groove and the moving groove until the end of the rotating rod away from the connecting plate contacts the spline shaft center, at which point the rotation of the positioning rod stops. Once the positioning rod contacts the spline shaft center, it prevents the spline from disengaging from the output shaft of the reducer during rotation, thus ensuring that the spline remains connected to the input shaft of the reducer, thereby improving the stability of the reducer during no-load testing.
[0014] Optionally, a dust cover is fixedly installed on the positioning plate, and the spherical shell is located inside the dust cover.
[0015] By adopting the above technical solution, during the rotation of the positioning rod, the ball will roll in the rolling groove and the moving groove. The dust cover can prevent external dust from entering the spherical shell, thereby preventing dust from adhering to the rolling groove and the moving groove and causing the ball to get stuck during rolling, thus improving the stability of the rotating rod during rotation.
[0016] Optionally, multiple fitting grooves are provided at intervals along the drive wheel, and multiple mating grooves are provided at intervals along the spline. The number of belts is the same as the number of fitting grooves and mating grooves.
[0017] By adopting the above technical solution, the arrangement of multiple belts can ensure that the drive wheel can drive the spline to rotate stably through multiple belts after it rotates. This avoids the situation where the drive wheel cannot rotate due to belt slippage caused by a single belt, thereby improving the stability of the spline during rotation.
[0018] Optionally, the end of the positioning rod that contacts the spline is tapered.
[0019] By adopting the above technical solution, after the positioning rod contacts the spline, the tapered positioning rod can make the contact between the positioning rod and the spline shaft more compact, avoiding the situation where the positioning rod is misaligned due to uneven force caused by excessive contact area after contact with the spline shaft, thereby improving the stability when the positioning rod contacts the spline shaft.
[0020] Optionally, a protective cover is fixedly installed on the workbench, and the protective cover is located on the side of the positioning plate away from the fixed plate.
[0021] By adopting the above technical solution, the protective cover can prevent vibration or foreign object splashing during the test of the reducer from causing injury to the operator, thereby improving the safety of the reducer during no-load testing.
[0022] In summary, the embodiments of the present invention provide a speed reducer no-load stability testing device, which includes at least one of the following beneficial technical effects: 1. When performing no-load testing on a speed reducer, place the speed reducer to be tested on a fixed component, which then secures the speed reducer to the worktable. After the speed reducer is fixed on the worktable, place the testing component onto the input shaft of the speed reducer. Start the testing component; once started, it will drive the input shaft of the speed reducer to rotate. This rotation of the input shaft allows for testing the speed reducer's operating condition under no-load conditions. During the rotation of the testing component, a positioning component is positioned to abut against the end of the testing component furthest from the speed reducer. This contact restricts the radial displacement of the testing component, ensuring it does not detach from the speed reducer. This method of testing the speed reducer's no-load operating condition avoids errors in the test results caused by discontinuous or uneven rotation of the input shaft during testing, thus improving the accuracy of no-load testing of the speed reducer.
[0023] 2. When testing the reducer, place the clamping plate on the worktable, ensuring it rests on the fixing plate. Secure the clamping plate and fixing plate to the worktable using clamping bolts. After fixing the fixing plate, place the reducer into the test hole. Secure the mounting plate to the fixing plate using mounting bolts, ensuring the mounting plate clamps the outer wall of the reducer. Once clamped, place the test piece onto the reducer's input shaft and activate the test piece. Activation will drive the reducer's input shaft to rotate, allowing for no-load testing of the reducer. This method of no-load testing avoids deviations in test results due to reducer vibration during testing, thus improving the accuracy of no-load testing.
[0024] 3. After the reducer is fixed on the mounting plate, the spline is fitted onto the reducer's input shaft. The motor is started, and its rotation drives the drive wheel, which in turn drives the belt, which in turn drives the spline, which in turn drives the reducer's input shaft. Once the input shaft rotates, the reducer can be tested under no-load conditions. This method of no-load testing avoids deviations in test results caused by the input shaft not rotating continuously and uniformly during the testing process, thus improving the accuracy of no-load testing.

[0027] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.
[0028] Combination Figure 1 , Figure 2 and Figure 7 This application discloses a speed reducer no-load stability testing device, including a workbench 1, a fixing member 2, a testing member 3, and a positioning member 4. The workbench 1 is fixedly set on the ground, and multiple fixing gaps 11 are horizontally arranged on the workbench 1. The fixing member 2 is fixedly set on the workbench 1, and the fixing member 2 can fix the speed reducer to be tested on the workbench 1. The testing member 3 is rotatably set on the ground, and the testing member 3 is arranged parallel to the fixing member 2. The testing member 3 can perform no-load testing on the speed reducer. The positioning member 4 is fixedly set on the workbench 1, and the positioning member 4 is arranged parallel to the fixing member 2. The positioning member 4 can ensure that the testing member 3 always keeps in contact with the speed reducer during the testing process.
[0029] In this embodiment, the workbench 1 has a rectangular structure and is fixed to the ground by bolt connection. The fixing gap 11 is a rectangular gap. The fixing member 2 is fixedly connected to the workbench 1 by bolt connection, and the positioning member 4 is fixedly connected to the workbench 1 by bolt connection.
[0030] In practical use, when a no-load test of the reducer is required, the reducer is placed inside the fixing component 2, and then fixed to the worktable 1 using the fixing component 2. After the fixing component 2 is fixed to the worktable 1, the testing component 3 is fitted onto the input shaft of the reducer. The testing component 3 is then activated, causing the input shaft of the reducer to rotate. Once the input shaft of the reducer rotates, the no-load test of the reducer can begin. During the rotation of the input shaft by the testing component 3, the positioning component 4 is rotated so that it contacts the end of the testing component 3 furthest from the input shaft. This contact ensures that the testing component 3 will not detach from the input shaft during rotation, guaranteeing that the testing component 3 remains in contact with the input shaft at all times.
[0031] Combination Figure 3 , Figure 4 and Figure 5In a specific embodiment, the fixing component 2 includes a fixing plate 21, mounting bolts 24, mounting plate 25, snap-fit bolts 26, and snap-fit plate 27. The fixing plate 21 is fixedly mounted on the workbench 1. The fixing plate 21 is fixedly provided with a detection hole 22, and multiple mounting bolts 24 are spaced apart on the fixing plate 21.

Each snap-fit bolt 26 is fixedly mounted within the fixing gap 11. Multiple snap-fit plates 27 are provided. Each snap-fit plate 27 is fixedly mounted on the workbench 1 by two snap-fit bolts 26, and the two ends of the fixing plate 21 are located between the snap-fit plate 27 and the workbench 1. The testing component 3 includes a testing plate 31, a motor 32, a drive wheel 33, a spline 35, and a belt 37. The testing plate 31 is fixedly mounted on the ground, the motor 32 is fixedly mounted on the testing plate 31, and the drive wheel 33 is rotatably mounted on the testing plate 31. The drive wheel 33 is fixedly connected to the output shaft of the motor 32. A vertically arranged fitting groove 34 is provided on the drive wheel 33. The spline 35 is fitted onto the input end of the reducer to be tested. A vertically arranged mating groove 36 is provided on the spline 35. The mating groove 36 has the same specifications as the fitting groove 34. One end of the belt 37 is wound around the fitting groove 34, and the other end of the belt 37 is wound around the mating groove 36. Multiple fitting grooves 34 are spaced apart along the drive wheel 33, and multiple mating grooves 36 are spaced apart along the spline 35. The number of belts 37 is the same as the number of fitting grooves 34 and mating grooves 36. A protective cover 6 is fixedly mounted on the worktable 1. The protective cover 6 is located on the side of the positioning plate 41 away from the fixed plate 21.
[0032] In this embodiment, the fixing plate 21 is rectangular, the detection hole 22 is circular, and the specifications of the detection hole 22 are consistent with the specifications of the motor 32 to be tested. The mounting hole 23 is circular, and the specifications of the mounting bolt 24 match the specifications of the mounting hole 23. The mounting plate 25 is annular, and the specifications of the snap-fit bolt 26 match the specifications of the fixing gap 11. The snap-fit plate 27 is rectangular. The detection plate 31 is rectangular and is fixed to the ground by bolt connection. The motor 32 is fixedly connected to the detection plate 31 by bolt connection. The drive wheel 33 can be fixedly connected to the output shaft of the motor 32 by integral molding or by welding, which is not specifically limited in this embodiment. The specifications of the spline 35 match the specifications of the input shaft of the motor 32.

After the snap-fit plate 27 is fixed to the worktable 1, the fixing plate 21 can be fixed to the worktable 1. After the fixing plate 21 is fixed, the reducer to be tested is placed in the test hole 22, and the mounting plate 25 is fixed to the fixing plate 21 with mounting bolts 24, so that the mounting plate 25 clamps the side wall of the reducer. After the mounting plate 25 clamps the reducer, the spline 35 is sleeved on the input shaft of the reducer. The motor 32 is started. After the motor 32 rotates, it drives the drive wheel 33 to rotate. After the drive wheel 33 rotates, it drives multiple belts 37 to rotate. After the multiple belts 37 rotate, they drive the spline 35 to rotate. After the spline 35 rotates, it drives the input shaft of the reducer to rotate. After the input shaft of the reducer rotates, the no-load test of the reducer can be performed. During the testing of the speed reducer, the protective cover 6 prevents parts from flying off due to vibration, thus ensuring the safety of operators and avoiding accidents.
[0034] Combination Figure 6 and Figure 7 In a specific embodiment, the positioning component 4 includes a positioning plate 41, positioning bolts 42, a connecting plate 43, a spherical shell 44, a star-shaped sleeve 45, ball bearings 48, and a positioning rod 49. The positioning plate 41 is fixedly mounted on the workbench 1, and is arranged parallel to the fixing plate 21. Two positioning holes are spaced apart at the bottom end of the positioning plate 41. Two positioning bolts 42 are spaced apart along the fixing gap 11. The positioning plate 41 is fixedly mounted on the workbench 1 by the positioning bolts 42, and the connecting plate 43 is fixedly mounted on the positioning plate 41. A spherical shell 44 is fixedly mounted on a connecting plate 43. Multiple rolling grooves 46 are spaced apart inside the spherical shell 44. A star-shaped sleeve 45 is rotatably mounted inside the spherical shell 44. Multiple moving grooves 47 are spaced apart on the surface of the star-shaped sleeve 45. Ball bearings 48 are arranged one-to-one with the rolling grooves 46 and the moving grooves 47, with each ball bearing 48 embedded between the moving groove 47 and the rolling groove 46. One end of a positioning rod 49 is fixedly connected to the end of the star-shaped sleeve 45 away from the spherical shell 44, and the other end of the positioning rod 49 abuts against the axis of the spline 35. A dust cover 5 is fixedly mounted on the positioning plate 41, and the spherical shell 44 is located inside the dust cover 5. The end of the positioning rod 49 that contacts the spline 35 is tapered.
[0035] In this embodiment, the positioning plate 41 has a rectangular structure, and the specifications of the positioning bolt 42 match the specifications of the fixing gap 11. The connecting plate 43 has a rectangular structure and can be fixedly connected to the positioning plate 41 by integral molding or by welding; no specific limitation is made in this embodiment. The specifications of the spherical shell 44 match the specifications of the planetary sleeve, the rolling groove 46 and the moving groove 47 are arc-shaped grooves, and the specifications of the ball bearing 48 match the specifications of the rolling groove 46 and the moving groove 47. The dust cover 5 has a cylindrical structure and can be fixedly connected to the positioning plate 41 by integral molding or by bolt connection; no specific limitation is made in this embodiment.
[0036] In practical use, as the spline 35 is fitted onto the input shaft of the reducer and drives the input shaft to rotate, the positioning rod 49 is rotated. The rotation of the positioning rod 49 causes the star-shaped sleeve 45 to rotate within the spherical shell 44. The rotation of the star-shaped sleeve 45 then causes the balls 48 to roll within the moving groove 47 and the rolling groove 46 until the conical end of the positioning rod 49 contacts the axis of the spline 35. Once the positioning rod 49 contacts the axis of the spline 35, it ensures that the spline 35 will not detach from the input shaft of the reducer during rotation, thus improving the stability of the spline 35 during rotation. The dust cover 5 prevents external dust from entering the spherical shell 44, thereby avoiding dust entering the rolling groove 46 and the moving groove 47, which could cause the balls 48 to become stuck or blocked during movement.
[0037] The principle of this embodiment is as follows: When the reducer needs to be tested, the snap-fit plate 27 is placed on the workbench 1, and the snap-fit plate 27 is positioned on the fixed plate 21. The snap-fit plate 27 and the fixed plate 21 are fixed on the workbench 1 by snap-fit bolts 26. After the fixed plate 21 is fixed, the reducer is placed in the test hole 22. The mounting plate 25 is fixed on the fixed plate 21 by mounting bolts 24, and the mounting plate 25 clamps the outer wall of the reducer. After the mounting plate 25 clamps the outer wall of the reducer, the spline 35 is sleeved on the input shaft of the reducer. The motor 32 is started. After the motor 32 rotates, it drives the drive wheel 33 to rotate. After the drive wheel 33 rotates, it drives the belt 37 to rotate. After the belt 37 rotates, it drives the spline 35 to rotate. After the spline 35 rotates, it drives the input shaft of the reducer to rotate. After the input shaft of the reducer rotates, the reducer can be tested under no-load conditions. After the spline 35 is fitted onto the reducer output shaft and begins to rotate, the positioning rod 49 is rotated. The rotation of the positioning rod 49 causes the star-shaped sleeve 45 to rotate synchronously. The rotation of the star-shaped sleeve 45 drives the balls 48 to roll within the rolling groove 46 and the moving groove 47 until the end of the rotating rod away from the connecting plate 43 contacts the axis of the spline 35. The rotation of the positioning rod 49 then stops. The contact between the positioning rod 49 and the axis of the spline 35 prevents the spline 35 from disengaging from the reducer output shaft during rotation, thus ensuring that the spline 35 remains connected to the reducer input shaft.
