Description

Technical Field

[0001] The present application relates to the technical field of reducer testing, and in particular to a testing platform, a testing system and a testing method. Background Art

[0002] With the development of automation technology, precision planetary reducers, as key transmission components, play a vital role in many fields. Before using this type of reducer, in order to accurately understand the performance of the reducer, a towing test bench is usually used to test the performance of the reducer.

[0003] In the related art, the towing test bench mainly includes: a main test assembly and a companion test assembly arranged relatively on a bottom plate. The reducer under test is included in the main test assembly; the torque performance and radial force performance of the reducer under test are tested by the cooperation of the main test assembly and the companion test assembly. In the towing test bench, radial force adjustment blocks are arranged on both sides of the radial direction of the reducer under test. The radial load of the reducer under test is manually adjusted by manually adjusting the radial force adjustment blocks, and then the radial force performance of the reducer under test is tested by loading different radial forces.

[0004] It can be seen that the drag test bench in the related art can only adjust the radial force applied to the reducer under test by manually adjusting the radial force adjustment block. Therefore, the radial force adjustment block needs to be manually adjusted many times during the entire test process, resulting in low test efficiency. Summary of the invention

[0099] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field based on the present application belong to the scope of protection of the present application.

[0100] In order to improve the testing efficiency of the reducer, an embodiment of the present application provides a testing platform, a testing system and a testing method, which are described in detail below.

[0101] See also Figure 1~Figure 3 ,in, Figure 1 A three-dimensional schematic diagram of a test platform provided in an embodiment of the present application from a first viewing angle; Figure 2 for Figure 1 The exploded schematic diagram of the test platform from the second perspective is shown; Figure 3 for Figure 1 The third perspective diagram of the test platform is shown in FIG. Figure 1~Figure 3 As shown, the test platform 1 comprises: a test base plate 10, a torque loading component 100 and a radial force loading component 200; wherein:

[0102] The torque loading component 100 is installed on the test base plate 10, and includes: a main test assembly 110 and a companion test assembly 160 which are arranged relatively along the first direction of the test base plate 10; wherein the main test assembly 110 includes: a coaxially connected main test motor 112, a measured reducer 111 and a sleeve wheel 114 sleeved on the outer periphery of the measured reducer 111; the companion test assembly 160 includes: a coaxially connected companion test motor 163 and a companion test reducer 161; a torque sensor 130 is connected between the output shaft of the measured reducer 111 and the output shaft of the companion test reducer 161;

[0103] The radial force loading component 200 includes: a radial force loading wheel 211 and a radial force loading wheel driving assembly 220 which are sequentially arranged along the second direction of the test base plate 10; the radial force loading wheel 211 is mounted on the test base plate 10 and is arranged close to the sleeve wheel 114; a pressure sensor 240 is arranged between the radial force loading wheel driving assembly 220 and the radial force loading wheel 211; the radial force loading wheel driving assembly 220 is used to drive the radial force loading wheel 211 to move forward and backward along the second direction toward the sleeve wheel 114 on the periphery of the measured reducer 111; so that the radial force loading wheel 211 can abut against the sleeve wheel 114 on the periphery of the measured reducer 111 after moving forward along the sleeve wheel 114 on the periphery of the measured reducer 111, thereby loading radial force on the measured reducer 111. Figure 1~Figure 3 As shown, the second direction Y is perpendicular to the first direction X.

[0104] It can be seen from the above-mentioned embodiments that the test platform provided by the embodiments of the present application tests the reducer under test by means of a torque loading component and a radial force loading component arranged on the test base plate. Among them, the radial force loading wheel driving assembly loads and unloads the radial force on the radial force loading wheel, and can realize multiple loading and unloading of the radial force, thereby realizing cyclic loading and unloading of the radial force. Therefore, by using the test platform provided by the embodiments of the present application, there is no need to manually adjust the radial force adjustment block multiple times to adjust the radial force loaded on the reducer under test, thereby improving the test efficiency of the reducer.

[0105] When using the above test platform for testing, the torque loading test can be performed using only the torque loading component 100 , or the torque loading component 100 and the radial force loading component 200 can be used simultaneously to perform the torque loading test and the radial force loading test.

[0106] When only the torque loading component 100 is used for the torque loading test, the main test motor 112 operates in the speed mode and the accompanying test motor 163 operates in the torque mode to provide resistance; when the reducer 111 under test is subjected to radial force, the radial force loading wheel driving assembly provides the required radial force, pushing the radial force loading wheel 211 to act on the sleeve wheel 114 on the outer periphery of the reducer 111 under test.

[0107] In this case, the sleeve will rotate with the rotation of the power output shaft of the reducer under test, and when the radial force loading wheel abuts against the sleeve under the driving force applied by the radial force loading wheel driving assembly, the radial force loading wheel will also rotate. In this way, the parts in the test platform will not be damaged. In addition, since the radial force loading wheel driving assembly can drive the radial force loading wheel to move forward and backward toward the sleeve along the second direction, the radial force can be loaded and unloaded multiple times, thereby realizing cyclic loading and unloading of the radial force.

[0108] Furthermore, since the driving force applied by the radial force loading wheel driving assembly will also change during the radial movement of the radial force loading wheel toward the outer periphery of the reducer under test, the radial force applied to the reducer under test will also change during this process. This allows different radial forces to be tested in one test process without the need to manually adjust the radial force adjustment block multiple times to adjust the radial force loaded on the reducer under test, thereby improving the test efficiency of the reducer.

[0109] Hereinafter, the radial force applying component 200 will be described in detail.

[0110] like Figure 1~Figure 3 As shown, in this embodiment, the height from the axis of the reducer 111 to the test base plate 10 can be the same as the height from the axis of the radial force loading wheel 211 to the test base plate 10, so that the torque of the radial force loaded each time is the same, thereby improving the accuracy of the test.

[0111] See also Figure 4 , Figure 4 for Figure 1 The right side view of the test platform is shown in Figure 1. Figure 4 As shown, the radial force loading component 200 further includes: a radial force loading wheel mounting seat 210 and a first sliding connection member 230 .

[0112] The radial force loading wheel 211 is rotatably mounted on the radial force loading wheel mounting seat 210; the pressure sensor 240 is mounted between the radial force loading wheel mounting seat 210 and the radial force loading wheel driving assembly 220; the radial force loading wheel mounting seat 210 is slidably mounted on the test base plate 10 along the second direction through the first sliding connection member 230. In this way, the radial force loading wheel 211 can be driven by the radial force loading wheel driving assembly 220 to move forward and backward along the second direction toward the radial direction of the sleeve wheel 114 on the outer periphery of the reducer 111 under test.

[0113] In this embodiment, the radial force loading wheel mounting seat 210 is slidably mounted on the test base plate 10 along the second direction through the first sliding connection member 230, so that when performing a radial force test, the radial force loading wheel 211 is less affected by friction during the process of loading radial force, thereby further improving the accuracy of the test.

[0114] In addition, the sleeve wheel 114 can be a rubber-coated wheel, and the rubber wrapped on the outside has a certain toughness, which can ensure the accurate loading of radial force and protect the measured reducer 111 from being damaged by excessive radial force. Of course, it can also be other types of wheels, and the sleeve wheel is not limited here, as long as it can be set on the periphery of the measured reducer 111 and can rotate with the rotation of the power output shaft of the measured reducer 111.

[0115] See also Figure 5 , Figure 5 for Figure 1 Schematic diagram of the exploded structure of the radial force loading wheel mounting seat in the test platform shown in FIG. Figure 5 As shown, the radial force loading wheel mounting seat 210 includes: a bottom bracket 212 and a loading wheel mounting cavity 213 formed above the bottom bracket. The bottom bracket 212 is slidably mounted on the test base plate 10 along the second direction through a first sliding connection member 230; the loading wheel mounting cavity 213 has an opening on the side facing the sleeve wheel 114, and a receiving plate 2131 on the side facing away from the sleeve wheel 114; the receiving plate 2131 is perpendicular to the test base plate 10, and the pressure sensor 240 is fixedly connected to the receiving plate 2131.

[0116] like Figure 5 As shown, the radial force loading wheel 211 is rotatably mounted in the loading wheel mounting cavity 213, and the radial force loading wheel 211 is close to the opening of the loading wheel mounting cavity 213. In this way, when the radial force loading wheel driving assembly 220 drives the radial force loading wheel mounting seat 210 to move in the radial direction of the sleeve wheel 114 on the outer periphery of the measured reducer 111, the radial force loading wheel mounting seat 210 only needs to move a small stroke to make the radial force loading wheel 211 abut against the sleeve wheel 114 on the outer periphery of the measured reducer 111, thereby reducing the time cost in the radial force loading process and further improving the test efficiency of the reducer.

[0117] Specifically, Figure 5 As shown, at the top of the bottom bracket 212, two mounting lower grooves 215 are arranged axially opposite to each other along the radial force loading wheel 211; the radial force loading wheel mounting seat 210 also includes: a left upper seat 217 and a right upper seat 218; the left upper seat 217 and the right upper seat 218 are respectively mounted on the two mounting lower grooves 215; the two mounting lower grooves 215, the left upper seat 217, the right upper seat 218 and the receiving plate 2131 together form the loading wheel mounting cavity 213.

[0118] like Figure 5 As shown, the bottom of the bottom bracket 212 is provided with two legs 2121 for supporting two mounting lower tanks;

[0119] The first sliding connection member 230 includes: a first slider 231 disposed at the bottom of the two legs, and a first slide rail 232 disposed along the second direction on the test base plate 10. In this way, the bottom bracket 212 can be slidably connected to the test base plate 10 through the first slider 231 disposed at the bottom of the two legs 2121 and the first slide rail 232 disposed on the test base plate 10.

[0120] like Figure 5As shown, in this embodiment, the two mounting lower grooves 215 are respectively provided with a left mounting lower groove 2151 and a right mounting lower groove 2152 with openings facing upward; the bottom of the left upper seat 217 and the right upper seat 218 are axially oppositely provided with a left mounting upper groove 2171 and a right mounting upper groove 2181 with openings facing downward along the radial force loading wheel 211; the left mounting upper groove 2171 and the right mounting upper groove 2181 correspond to the positions of the left mounting lower groove 2151 and the right mounting lower groove 2152, respectively, to form two loading wheel axle mounting holes.

[0121] In this embodiment, the radial force loading wheel 211 includes a loading wheel body 2111 and a loading wheel axle 2112 axially extending from both sides of the loading wheel body; in this way, the loading wheel axle 2112 is rotationally connected to the radial force loading wheel mounting seat 210 through two loading wheel axle mounting holes.

[0122] like Figure 5 As shown, in this embodiment, the left mounting lower groove 2151 includes: a left lower mounting semicircular hole 21511 and a left lower fixed shoulder 21512 located on both sides of the radial direction of the lower left mounting semicircular hole 21511, and the lower left mounting semicircular hole 21511 and the left lower fixed shoulder 21512 are connected; the right mounting lower groove 2152 includes: a right lower mounting semicircular hole 21521 and a right lower fixed shoulder 21522 located on both sides of the radial direction of the lower right mounting semicircular hole 21521, and the lower right mounting semicircular hole 21521 and the right lower fixed shoulder 21522 are connected.

[0123] The left mounting upper groove 2171 includes: an upper left mounting semicircular hole 21711 and an upper left fixed shoulder 21712 located on both sides of the radial direction of the upper left mounting semicircular hole 21711; the upper left mounting semicircular hole 21711 and the upper left fixed shoulder 21712 are connected; the right mounting upper groove 2181 includes: an upper right mounting semicircular hole 21811 and an upper right fixed shoulder 21812 located on both sides of the radial direction of the upper right mounting semicircular hole 21811; the upper right mounting semicircular hole 21811 and the upper right fixed shoulder 21812 are connected.

[0124] Among them, the upper left fixed shoulder 21712 and the lower left fixed shoulder 21512 are detachably connected so that the upper left mounting semicircular hole 21711 and the lower left mounting semicircular hole 21511 are closed to form a loading axle mounting hole; the upper right fixed shoulder 21812 and the lower right fixed shoulder 21522 are detachably connected so that the upper right mounting semicircular hole 21811 and the lower right mounting semicircular hole 21521 are closed to form a loading axle mounting hole.

[0125] like Figure 5As shown, the above-mentioned left upper seat 217 also includes: a left upper side plate 2172; the left upper side plate 2172 is arranged on the side of the left mounting upper groove 2171 close to the right upper seat 218; the above-mentioned right upper seat 218 also includes: a right upper side plate 2182; the right upper side plate 2182 is arranged on the side of the right mounting upper groove 2181 close to the left upper seat 217.

[0126] Specifically, the loading wheel axle 2112 is rotatably connected to the loading wheel axle mounting hole through the bearing 201, the distance ring 202 and the bearing pressure plate 203; a bearing pressure plate 203 is installed on each end surface of the two loading wheel axle mounting holes that are away from each other; the bearing 201 and the distance ring 202 are sequentially mounted on the two loading wheel axles 2112 along the direction in which the two loading wheel axles 2112 are away from each other.

[0127] It is understandable that a shoulder 2141 is provided on the side close to each other on the loading axle mounting hole; the shoulder 2141 and the distance ring 202 can axially position the bearing 201, and the axial clearance can also be adjusted through the distance ring 202.

[0128] In some examples, when the bearing 201 is a spherical roller bearing with sealing covers on both sides, since the bearing 201 has its own grease inside and is sealed, it is not necessary to provide the oil seal ring 216 and the grease adding hole 219;

[0129] However, when the bearing 201 is a bearing without a sealing cover, in order to lubricate the bearing 201, a grease adding hole 219 can be set on the left mounting upper groove 2171, the right mounting upper groove 2181 and the bearing pressure plate 203, and the outer ring of the bearing 201 is provided with an oil filling hole in the radial direction, and the roller between the outer ring and the inner ring of the bearing 201 has cavities on both sides in the axial direction, and the grease adding hole 219 is connected with the oil filling hole and the cavity on the side of the roller of the bearing 201. In this way, grease can be added to the bearing 201 in the loading wheel shaft mounting hole through the grease adding hole 219. Among them, the bearing can be a deep groove ball bearing, a cylindrical roller bearing, etc., and the roller of the bearing 201 can be a steel ball in the middle of a deep groove ball bearing, or a cylinder in the middle of a cylindrical roller bearing, etc.

[0130] In addition, in order to reduce the loss of grease in the bearing 201 , oil seal rings 216 can be respectively sleeved on the loading wheel shaft 2112 on both sides of the loading wheel body 2111 ; the oil seal ring 216 is installed on the side of the bearing 201 close to the loading wheel body 2111 .

[0131] In addition, a limit assembly 233 is fixed on the test base plate 10, and the limit assembly 233 is used to limit the sliding distance of the radial force loading wheel mounting seat 210 close to the sleeve wheel 114. In this way, when the radial force applied is too large and unattended, the driving cylinder 221 can be prevented from pushing the radial force loading wheel 211 and the sleeve wheel 114 without restriction to cause friction and cause accidents, and avoid damage to the reducer 111 under test.

[0132] In a possible implementation, the limiting assembly 233 may be a mechanical limiting component, which may be installed at a position corresponding to the maximum radial force on the first sliding connector 230 based on experience to prevent the radial force loading wheel mounting seat 210 from approaching the sleeve wheel 114 without restriction.

[0133] In other implementations, the limit assembly 233 may also be a limit switch, and the limit switch may be implemented by a proximity switch.

[0134] Specifically, the limit switch can be arranged on one side of the radial force loading wheel mounting seat 210 along the first direction, fixed on the test base plate 10, and there is a gap between the radial force loading wheel mounting seat 210. In this way, the radial force loading wheel mounting seat 210 will not generate friction with the limit assembly 233 during the movement, thereby avoiding damage to the limit assembly 233.

[0135] Among them, the limit switch can be electrically connected to a controller, and the controller is electrically connected to the above-mentioned servo motor, and is installed at the position corresponding to the maximum radial force on the first sliding connection 230 according to experience. When the radial force loading wheel mounting seat 210 does not reach the position corresponding to the maximum radial force, the limit switch will send a signal. At this time, the controller will detect the signal sent by the limit switch and will not send a stop command to the servo motor. The servo motor will continue to run to apply radial force to the radial force loading wheel 211; when the radial force loading wheel mounting seat 210 reaches the position corresponding to the maximum radial force, the limit switch does not send a signal to the controller. At this time, the controller cannot detect the signal sent by the limit switch, and controls the servo motor to stop, thereby stopping the application of radial force to the radial force loading wheel 211.

[0136] In this embodiment, Figure 1~Figure 4As shown, the radial force loading wheel driving assembly 220 includes: a driving cylinder 221, a cylinder driving member 222 and a cylinder mounting bracket 223; the cylinder mounting bracket 223 is fixedly mounted on a side of the test base plate 10 away from the radial force loading wheel 211; the driving cylinder 221 is fixed on the cylinder mounting bracket 223 to drive the radial force loading wheel 211 to move forward and backward along the radial direction of the sleeve wheel 114 toward the outer periphery of the reducer 111 under test; the pressure sensor 240 is arranged on a side of the radial force loading wheel mounting bracket 210 close to the driving cylinder 221, and when the driving rod 2211 of the driving cylinder 221 is extended, the end of the driving rod 2211 abuts against the pressure sensor 240.

[0137] In this embodiment, the cylinder driving component 222 can be a hydraulic driving component, a pneumatic driving component or a servo motor.

[0138] When the cylinder driving member 222 is a hydraulic driving member, the driving cylinder 221 may be a hydraulic cylinder. In this case, the hydraulic driving member may include: a hydraulic pipeline, a hydraulic pump, and a hydraulic oil tank. In this way, the hydraulic pump may pump the hydraulic oil in the hydraulic oil tank into the hydraulic cylinder through the hydraulic pipeline, so that the driving rod 2211 of the hydraulic cylinder extends out of the hydraulic cylinder, thereby realizing the radial force applied to the radial force loading wheel 211.

[0139] When the cylinder driving member 222 is a pneumatic driving member, the driving cylinder 221 may be a cylinder. In this case, the pneumatic driving member may include: a pneumatic pipeline and a pneumatic pump. In this way, the pneumatic pump may pump air into the cylinder through the pneumatic pipeline, so that the driving rod 2211 of the cylinder extends out of the cylinder, thereby realizing the radial force being applied to the radial force loading wheel 211.

[0140] When the cylinder driving member 222 is a servo motor, the driving cylinder 221 can be an electric cylinder. At this time, the servo motor is in a torque mode, and the servo motor can drive the driving rod 2211 of the electric cylinder to extend out of the electric cylinder, thereby applying radial force to the radial force loading wheel 211.

[0141] like Figure 1~Figure 4 As shown, in this embodiment, the upper part of the cylinder mounting bracket 223 is provided with a through hole 2231 for the driving rod 2211 of the driving cylinder 221 to pass through; the driving cylinder 221 is installed on the side of the cylinder mounting bracket 223 away from the radial force loading wheel 211, and the driving rod 2211 passes through the through hole 2231 toward the radial force loading wheel 211. In this embodiment, the cylinder mounting bracket 223 and the through hole 2231 can raise the driving rod 2211 to be consistent with the center height of the radial force loading wheel 211. In this way, it can be ensured that the torque of the radial force loaded to the radial force loading wheel 211 is the same each time, thereby improving the accuracy of the test.

[0142] Next, the torque applying component 100 will be described in detail.

[0143] See also Figure 1~Figure 3 , Figure 6 as well as Figure 7 ,in, Figure 6 for Figure 1 A front view of the test platform shown; Figure 7 for Figure 1 The three-dimensional schematic diagram of the torque loading components in the test platform is shown in FIG. Figure 1~Figure 3 , Figure 6 as well as Figure 7 As shown, the main test assembly 110 further includes: a mounting bracket 113 for the reducer to be tested; and the accompanying test assembly 160 further includes: a mounting bracket 164 for the accompanying test reducer.

[0144] Among them, the tested reducer 111 is installed on the tested reducer mounting bracket 113, and the tested reducer mounting bracket 113 is fixedly installed on the test base plate 10; the accompanying test reducer 161 is installed on the accompanying test reducer mounting bracket 164, and the accompanying test reducer mounting bracket 164 is installed on the test base plate 10.

[0145] like Figure 2 and Figure 3 As shown, the test base plate 10 is provided with a plurality of mutually parallel mounting grooves 412 along a first direction, and a second sliding connection member 170 is provided along the first direction; the reduced speed device mounting bracket 113 under test is fixedly mounted on the test base plate 10 via a first fixed connection member 4131 provided in the mounting groove 412. Figure 1~Figure 4 As shown, the above-mentioned test platform may further include: an axial positioning seat 180 .

[0146] The test reducer mounting bracket 164 can slide relative to the test base plate 10 under the action of external force through the second sliding connection 170, and after the test reducer mounting bracket 164 slides to a fixed position, it is fixed on the test base plate 10 through the axial positioning seat 180.

[0147] Specifically, the mounting slot 412 may be a T-slot, the first fixed connector 4131 may be a T-bolt and a nut, the nut of the T-bolt is placed in the T-slot, and the screw of the T-bolt extends out of the T-slot, and then the reduced speed device mounting bracket 113 under test may be fixed to the test base plate 10 by the T-bolt and the nut. In this way, when the reduced speed devices 111 under test of different models and sizes are tested, the reduced speed device mounting bracket 113 under test that matches the size of the reduced speed device 111 under test may be installed, thereby improving the flexibility and extensiveness of the test platform using the embodiment of the present application.

[0148] like Figure 2 , Figure 3 , Figure 6 and Figure 7As shown, the second sliding connection member 170 may include a second slider 171 disposed at the bottom of the test reducer mounting bracket 164, and a second slide rail 172 disposed on the test base plate 10. The test reducer mounting bracket 164 may be fixedly connected to the second slider 171 disposed at the bottom of the test reducer mounting bracket 164 through a second fixed connection member 4132, and the second slide rail 172 may be disposed on the test base plate along a first direction, so that the test reducer mounting bracket 164 may be slidably connected to the test base plate 10 through the second slider 171 disposed at the bottom and the second slide rail 172 disposed on the test base plate 10. In this way, when testing the test reducers 111 of different models and sizes, the axial distance between the test reducer 111 and the test reducer 161 may be adjusted, so as to facilitate installation and disassembly.

[0149] The second fixed connecting member 4132 can be an ordinary bolt. When the test reducer mounting bracket 164 slides to a fixed position where the test reducer mounting bracket 164 can be fixed under the action of external force, the ordinary bolt can pass through the mounting hole on the test reducer mounting bracket 164 and enter the mounting hole on the test base plate to fix the test reducer mounting bracket 164 on the test base plate 10.

[0150] Specifically, Figure 1~Figure 3 As shown, the bottom of the axial positioning seat 180 is fixed to the test base plate 10 by a third fixed connector 4133 arranged in the mounting groove 412; one side of the axial positioning seat 180 is fixedly connected to an end of the test reducer mounting bracket 164 away from the measured reducer mounting bracket 113, so as to position and install the test reducer mounting bracket 164 after the test reducer mounting bracket 164 slides to a fixed position.

[0151] In this way, it is convenient to perform radial force test on the tested reducer 111, and the axial positioning seat 180 can also position and install the test reducer mounting bracket 164 corresponding to the test reducer 161 of different models and sizes. Among them, the third fixing connector 4133 can be a T-bolt nut.

[0152] In addition, if Figure 1~Figure 3 as well as Figure 7 As shown, the upper portion of the tested reducer mounting bracket 113 is provided with a main test motor mounting hole 1131 for the main test motor 112 to pass through, and the upper portion of the accompanying test reducer mounting bracket 164 is provided with an accompanying test motor mounting hole 1641 for the accompanying test motor 163 to pass through.

[0153] The main test motor 112 passes through the main test motor mounting hole 1131 and is connected to the power input end of the tested reducer 111 , and the power output end of the tested reducer 111 is connected to the sleeve 114 ; the accompanying test motor 163 passes through the accompanying test motor mounting hole 1641 and is connected to the power input end of the accompanying test reducer 161 .

[0154] In this way, the center of gravity of the main test motor 112 and the center of gravity of the tested reducer 111 can be respectively located on both sides of the tested reducer mounting bracket 113, which is conducive to balanced weight distribution on both sides of the tested reducer mounting bracket 113, and the center of gravity of the accompanying test motor 163 and the center of gravity of the accompanying test reducer 161 can be respectively located on both sides of the accompanying test reducer mounting bracket 164, which is conducive to balanced weight distribution on both sides of the accompanying test reducer mounting bracket 164.

[0155] In this embodiment, see Figure 6~Figure 9 ,in, Figure 8 for Figure 1 The schematic diagram of the decomposition structure of the main test components in the test platform shown; Fig. 9 for Figure 1 A cross-sectional view of the main test assembly in the test platform is shown.

[0156] like Figure 6~Figure 9 As shown, the test platform also includes: two couplings 120; the main test component 110 also includes: a main test adapter frame 115, and the accompanying test component 160 also includes: an accompanying test adapter frame 162; the sleeve 114 is coaxially connected to the main test adapter frame 115, and the power output end of the accompanying test reducer 161 is connected to the accompanying test adapter frame 162.

[0157] The main test adapter 115 is coaxially connected to the torque sensor 130 through a coupling 120, and the companion test adapter 162 is coaxially connected to the torque sensor 130 through another coupling 120. In this way, the main test assembly 110, the companion test assembly 160 and the torque sensor 130 can be connected through the main test adapter 115, the companion test adapter 162 and the coupling 120.

[0158] Among them, the main test motor 112 can be fixedly connected to the tested reducer 111 by bolts, and the tested reducer 111 is fixedly connected to the tested reducer mounting bracket 113 by bolts; the sleeve 114 and the main test adapter frame 115 are fixedly connected to the tested reducer 111 by bolts; the accompanying test motor 163 is fixedly connected to the accompanying test reducer 161 by bolts, the accompanying test reducer 161 is fixedly connected to the accompanying test reducer mounting bracket 164 by bolts, and the accompanying test adapter frame 162 is fixedly connected to the accompanying test reducer 161 by bolts.

[0159] In this embodiment, the structures of the main test adapter 115 and the companion test adapter 162 may be the same.

[0160] Specifically, Figure 8 As shown, the main test adapter 115 and the companion test adapter 162 both include: a connecting flange 1151 and a transfer shaft 1152; the connecting flange 1151 and the transfer shaft 1152 are fixedly connected; the sleeve 114 is coaxially connected to the connecting flange 1151 of the main test adapter 115, and the power output end of the companion test reducer 161 is coaxially connected to the connecting flange 1151 of the companion test adapter 162; the transfer shaft 1152 of the main test adapter 115 is coaxially connected to the torque sensor 130 through a coupling 120, and the transfer shaft 1152 of the companion test adapter 162 is coaxially connected to the torque sensor 130 through another coupling 120.

[0161] In addition, when the torque sensor 130 is relatively small in height and smaller than the height of the rear coupling after installation, and cannot be directly installed on the test base plate 10, a torque sensor mounting bracket 150 can be provided. In this way, the torque sensor 130 can be fixedly mounted on the torque sensor mounting bracket 150, so that the height of the torque sensor 130 is consistent with the height of the rear coupling after installation. Then, the torque sensor mounting bracket 150 is slidably mounted on the test base plate 10. In this embodiment, the torque sensor mounting bracket 150 is slidably mounted on the test base plate 10, and can be adapted to couplings of different lengths, thereby improving compatibility.

[0162] Specifically, Figure 1 , Figure 2 , Figure 6 and Figure 7 As shown, a third slider 173 can be fixedly installed at the bottom of the torque sensor mounting bracket 150 , and the third slider 173 is slidably connected to the second slide rail 172 , so that the torque sensor mounting bracket 150 can be slidably installed on the test base plate 10 .

[0163] like Figure 7 As shown, a rubber pad 140 may be further provided between the torque sensor 130 and the torque sensor mounting bracket 150 to reduce the influence of vibration or impact of the test platform on the test result of the torque sensor and improve the test accuracy of the torque sensor.

[0164] In addition, the test base plate 10 of the embodiment of the present application can be implemented by a single base plate, or by splicing two base plates. Figure 2 and Figure 3As shown, in this embodiment, the test base plate 10 may include: a first base plate 400 and a second base plate 500; wherein the first base plate 400 is arranged along the first direction, the second base plate 500 is arranged along the second direction, and the first base plate 400 and the second base plate 500 are fixedly connected in the horizontal direction; the main test component 110 and the accompanying test component 160 are relatively arranged on the first base plate 400 along the first direction; the radial force loading wheel 211 and the radial force loading wheel driving component 220 are sequentially arranged on the second base plate 500 along the second direction.

[0165] In this way, different components can be installed on different base plates, making it convenient to disassemble and assemble different components.

[0166] Specifically, Figure 1~Figure 3 As shown, the test platform further includes: a bottom plate connector 300; a first bottom plate 400 and a second bottom plate 500 are respectively detachably fixedly connected to the bottom plate connector 300, and the distance between the first bottom plate 400 and the second bottom plate 500 is adjustable. In this way, when testing the reducers 111 of different models and sizes, or when using the sleeve wheels 114 of different sizes or the radial force loading wheels 211 of different sizes, the distance between the first bottom plate 400 and the second bottom plate 500 can be adjusted as needed.

[0167] In addition, if Figure 1~Figure 3 As shown, a wheel receiving opening 410 may also be provided on the first bottom plate 400, and the position of the wheel receiving opening 410 corresponds to the installation position of the wheel 114, and is used to receive wheels 114 of different sizes. In this way, the test platform provided by the embodiment of the present application can replace wheels 114 of different sizes for testing.

[0168] Based on the test platform 1 provided in the embodiment of the present application, the test can be automatically performed by a controller. Therefore, the test platform provided in the embodiment of the present application can also include a controller 20, such as Fig.10 As shown, Figure 1 Schematic diagram of the electrical connection relationship between the controller and other components in the test platform shown; the controller 20 can be electrically connected to the main test motor 112, the companion test motor 163, the torque sensor 130, the radial force loading wheel drive assembly 220 and the pressure sensor 240.

[0169] The controller 20 can receive the motor start instruction and the radial force loading instruction, control the main test motor 112 and the accompanying test motor 163 to start based on the motor start instruction, and receive the torque information fed back by the torque sensor 130; and control the radial force loading wheel driving assembly 220 to drive the radial force loading wheel 211 to move forward and backward along the second direction toward the sleeve wheel 114 on the periphery of the measured reducer 111 based on the radial force loading instruction; so that the radial force loading wheel 211 can abut against the sleeve wheel 114 on the periphery of the measured reducer 111 after moving forward along the sleeve wheel 114 toward the periphery of the measured reducer 111, load the radial force on the measured reducer 111, and receive the pressure information fed back by the pressure sensor 240. In this way, the radial force can be loaded and unloaded multiple times, and the cyclic loading and unloading of the radial force can be realized.

[0170] On this basis, as mentioned above, Figure 1 and Figure 4 The limit assembly 233 provided on the test base plate 10 shown in the figure can also be a limit switch, which can be implemented by a proximity switch. The limit switch can be electrically connected to the controller 20 mentioned above, and the controller is electrically connected to the servo motor mentioned above to realize the automatic shutdown of the servo motor.

[0171] Based on the above test platform, the present application embodiment also provides a test system, such as Fig.11 , is a schematic diagram of the structure of the test system provided in the embodiment of the present application; the test system includes a host computer 2 and a test platform 1, the test platform 1 is Figure 1 to Figure 9 Any of the test platforms shown; the host computer 2 can be a desktop computer, a notebook, etc.

[0172] The test platform 1 is provided with a controller 20, which is electrically connected to the main test motor 112, the accompanying test motor 163, the torque sensor 130, the radial force loading wheel drive assembly 220 and the pressure sensor 240;

[0173] The host computer 2 is used to send a motor start instruction and a radial force loading instruction to the controller 20; the radial force loading instruction may include a cyclic loading and unloading instruction.

[0174] The controller 20 is used to receive the motor start instruction and the radial force loading instruction, and based on the motor start instruction, control the main test motor 112 and the accompanying test motor 163 to start, and receive the torque information fed back by the torque sensor 130;

[0175] Furthermore, based on the radial force loading instruction, the radial force loading wheel driving assembly 220 is controlled to drive the radial force loading wheel 211 to move forward and backward along the second direction toward the sleeve wheel 114 on the periphery of the reducer 111 under test; so that after the radial force loading wheel 211 moves forward along the sleeve wheel 114 on the periphery of the reducer 111 under test, it can abut against the sleeve wheel 114 on the periphery of the reducer 111 under test, load radial force on the reducer 111 under test, and receive pressure information fed back by the pressure sensor 240.

[0176] Corresponding to the above-mentioned test system, the present application embodiment also provides a test method, such as Fig.12 The figure is a flow chart of the test method provided in the embodiment of the present application, and the test method is applied to Fig.11 The test system shown, the test method comprises:

[0177] S1210, the host computer sends a motor start instruction and a radial force loading instruction to the controller;
