Description

Technical Field

[0001] This utility model relates to the field of speed reducer testing, and more particularly to a speed reducer testing platform. Background Technology

[0002] Gearboxes typically undergo testing before leaving the factory. Current testing methods often involve driving the gearbox with an electric motor to test its stability; this involves rotating the gearbox for an extended period to assess its stability. However, this method has drawbacks. Since the gearbox's output is not under load during the test, it is essentially tested under no-load conditions. Even if this test meets the requirements, the actual operating environment of the gearbox differs significantly from the testing environment due to the frequent loading. Consequently, the parameters obtained from the pre-shipment test have a large discrepancy with the parameters obtained in actual use, making the test inaccurate. Utility Model Content

[0003] In order to overcome the shortcomings of the existing technology, this utility model provides a speed reducer testing platform.

[0004] This utility model is achieved by the following technical solution: a speed reducer test platform, including a test bench and a simulated load component. The test bench is provided with a position adjustment component, the simulated load component is disposed on the adjustment component, and a placement seat is provided on one side of the simulated load component. The placement seat is used to place the speed reducer to be tested.

[0005] When the speed reducer is placed on the mounting base, the position adjustment component adjusts the simulated load component to be coaxial with the speed reducer, and the speed reducer and the simulated load component are connected through a first coupling. When the speed reducer rotates, it drives the simulated load component to rotate through the first coupling.

[0006] The position adjustment component includes a mounting base and a lifting component. The mounting base is fixed on the test bench, the lifting component is disposed on the mounting base, and the simulated load component is disposed on the lifting component and is driven to move up and down by the lifting component.

[0007] The lifting component includes an adjusting screw, a slider, and a lifting seat. The adjusting screw is inserted into the mounting seat and rotates. The slider is sleeved on the adjusting screw and threadedly connected to the adjusting screw. The rotation of the adjusting screw drives the slider to reciprocate up and down along the length of the screw. The lifting seat is fixed on the slider. The movement of the slider drives the lifting seat to reciprocate. The simulated load component is fixed on the lifting seat.

[0008] The mounting base includes a base and a support base. The base includes a bottom plate and a vertical plate. The bottom plate and the vertical plate are fixed to each other and perpendicular to each other. The bottom plate is fixed to the test platform, and the vertical plate is perpendicular to the test platform. The support base includes a support plate, a lower horizontal plate, and an upper horizontal plate. The support plate abuts against and is fixed to the vertical plate. The upper horizontal plate is fixed to the top of the support plate and is parallel to the bottom plate. The lower horizontal plate is fixed to the bottom plate.

[0009] The upper and lower horizontal plates are provided with holes, the adjusting screw passes through the holes, and the slider is sleeved on the adjusting screw between the upper and lower horizontal plates. The rotation of the adjusting screw drives the slider to reciprocate between the upper and lower horizontal plates.

[0010] The end of the adjusting screw extends out of the upper horizontal plate, and a handwheel is sleeved and fixed to the end of the adjusting screw. The rotation of the handwheel drives the adjusting screw to rotate.

[0011] A through hole is made on the test bench, and an electric motor is installed at the bottom of the test bench. The shaft of the electric motor passes through the through hole and is connected to the reducer through a second coupling.

[0012] A crossbeam is provided above the test bench, and the crossbeam is located above the reducer. A cylinder is provided on the crossbeam, and a downward pressure head is provided at one end of the cylinder shaft that passes through the crossbeam. When the reducer rotates, the cylinder drives the downward pressure head to press against the reducer.

[0013] Compared to existing technologies, this invention simulates the loaded state of a speed reducer by using a motor to drive the reducer during testing, with the reducer's output end under load. Furthermore, to accommodate tests of speed reducers of different sizes, the height of the simulated load component can be adjusted using a height adjustment mechanism, allowing it to be concentric with different specifications of speed reducers. This means the same load can be used to test various types of speed reducers, broadening its application range. Simultaneously, a pressure head is used to press firmly against the speed reducer during testing, reducing the impact of speed reducer vibration on the test results and making the results more accurate.

[0018] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0019] Reference Figure 1-3 A test platform for a speed reducer 4 includes a test bench 1 and a simulated load component 3. The test bench 1 is equipped with a position adjustment component 2, and the simulated load component 3 is mounted on the adjustment component. A placement seat 25 is provided on one side of the simulated load component 3 for placing the speed reducer 4 to be tested. When the speed reducer 4 needs to be tested, it is connected to the simulated load component 3 so that the simulated load component 3 can drive the speed reducer 4 during operation. This simulates the actual working environment of the speed reducer 4 during testing, making the test parameters of the speed reducer 4 more accurate. In this embodiment, the simulated load component 3 can be a worm gear reducer 4, that is, the worm gear reducer 4 is used to simulate the load carried by the speed reducer 4 under test during operation.

[0020] Because the specifications of the reducer 4 are different, it is often not concentric with the simulated load assembly 3 when placed on the mounting base 25. Therefore, it is necessary to adjust the position of the simulated load assembly 3 to ensure smooth connection between the simulated load assembly 3 and the reducer 4 during the test. That is, the position adjustment component 2 is used to adjust the simulated load assembly 3 and the reducer 4 to be coaxial. The reducer 4 and the simulated load assembly 3 can be connected by the first coupling 9. When the reducer 4 rotates, it drives the simulated load assembly 3 to rotate through the first coupling 9.

[0021] In this embodiment, the position adjustment component 2 includes a mounting base 21 and a lifting component 22. The mounting base 21 is fixed on the test bench 1, the lifting component 22 is mounted on the mounting base 21, and the simulated load component 3 is mounted on the lifting component 22 and is driven to move up and down by the lifting component 22. In this embodiment, the lifting component 22 includes an adjusting screw 221, a slider 222, and a lifting seat 223. The adjusting screw 221 is inserted into the mounting base 21 and rotates. The slider 222 is sleeved on the adjusting screw 221 and threadedly connected to the adjusting screw 221. The rotation of the adjusting screw 221 drives the slider 222 to reciprocate up and down along the length of the screw. The lifting seat 223 is fixed on the slider 222. The movement of the slider 222 drives the lifting seat 223 to move back and forth. The simulated load component 3 is fixed on the lifting seat 223. When the lifting seat 223 moves, it can drive the simulated load component 3 to move.

[0022] Specifically, since the simulated load component 3 is typically quite heavy, the mounting base 21 includes a base 211 and a support base 212. The base 211 includes a bottom plate 2111 and a vertical plate 2112, which are fixed to each other and perpendicular to each other. The bottom plate 2111 is fixed to the test bench 1, and the vertical plate 2112 is perpendicular to the test bench 1. The support base 212 includes a support plate, a lower horizontal plate, and an upper horizontal plate 2123. The support plate abuts against and is fixed to the vertical plate 2112. The upper horizontal plate 2123 is fixed to the top of the support plate and is parallel to the bottom plate 2111. The lower horizontal plate is fixed to the bottom plate 2111. By utilizing the base 211 and the support base 212 to jointly bear the weight of the simulated load component, the simulated load component 3 becomes more stable during testing, reducing the impact on test parameters and improving test accuracy.

[0023] Holes are provided on the upper horizontal plate 2123 and the lower horizontal plate, through which the adjusting screw 221 passes. A slider 222 is fitted onto the adjusting screw 221 between the upper and lower horizontal plates. Rotation of the adjusting screw 221 causes the slider 222 to reciprocate between the upper and lower horizontal plates. The end of the adjusting screw 221 extends out of the upper horizontal plate 2123, and a handwheel 224 is fitted and fixed to the end of the adjusting screw 221. Rotation of the handwheel 224 causes the adjusting screw 221 to rotate. When adjustment is needed, rotating the handwheel 224 causes the adjusting screw 221 to rotate, thereby raising and lowering the simulated load group to accommodate tests of different specifications of reducers 4. This ensures that the input end of the simulated load is always coaxial with the output end of the reducer 4, facilitating the testing of different specifications of reducers 4 and broadening the applicability of the testing platform.

[0024] In this embodiment, since both the simulated load component 3 and the position adjustment component 2 are placed on one side of the test bench 1, a through hole is made on the test bench 1 to maintain the overall balance of the test bench 1. A motor 5 is installed at the bottom of the test bench 1, and the shaft of the motor 5 passes through the through hole and is connected to the reducer 4 through the second coupling 10. On the one hand, the motor 5 serves as an overall counterweight, and on the other hand, the reducer 4 only needs to be placed on the mounting base 25 by means of hoisting or other methods and the input end of the reducer 4 is connected to the second coupling 10, making the installation more convenient.

[0025] Throughout the testing process, the reducer 4 needs to be started, but there is no substantial connection between the reducer 4 and the test bench 1. It is only fixed by the second coupling 10. Therefore, the reducer 4 may vibrate during the test, thus interfering with the test results. To reduce the impact of reducer vibration on the test results, a crossbeam 6 can be installed above the test bench 1. The crossbeam 6 is located above the reducer 4, and a cylinder 7 is installed on the crossbeam 6. A downward pressure head 8 is installed at one end of the shaft of the cylinder 7 that passes through the crossbeam 6. When the reducer 4 rotates, the cylinder 7 drives the downward pressure head 8 to press against the reducer 4. During the test of the reducer 4, the downward pressure head 8 is always in contact with the reducer 4 to reduce the vibration of the reducer 4 during the test, so that the reducer 4 remains stable during the test, thereby reducing its impact on the test results and making the test results more accurate.

[0026] Compared to existing technologies, this invention uses a motor 5 to drive a reducer 4 during testing, with the output end of the reducer 4 under load, thus simulating the loaded state of the reducer 4 during testing. Furthermore, to accommodate tests of reducers 4 of different sizes, the height of the simulated load component 3 can be adjusted using a height adjustment component, allowing it to be concentric with reducers 4 of different specifications. This enables the same load to be used for testing various models of reducers 4, broadening its application range. Simultaneously, a downward pressure head 8 is used to press against the reducer 4 during testing, reducing the impact of reducer 4 vibration on the test results and making the results more accurate.

[0027] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
