[0046] When testing the reducer 4 , it is necessary to perform radial loading and torque loading on the reducer 4 to simulate the actual operating condition of the reducer 4 .

[0047] In the actual use of some reducers 4, the output end of the reducer 4 will be subjected to a large radial force. However, in the current technology, when testing the reducer 4, due to structural limitations, in order to ensure the accuracy of the data, it is impossible to apply a large radial force to the reducer 4, and it is impossible to test some reducers 4 that are under a large load in the radial direction.

[0048] In order to solve the technical problem that a large radial force cannot be applied in the test of the reducer 4, a reducer 4 test device is provided in the first embodiment of the present application. Figure 1 , Figure 1Schematic diagram of the structure of the reducer 4 test equipment provided in an embodiment of the present application, the reducer 4 test equipment includes a driving device 1, a loading device 2 and a load device 3, the driving device 1 is configured to be connected to the input end of the reducer 4 and drive the input end to rotate; the loading device 2 and the driving device 1 are arranged at intervals along a first direction X, the first direction X is the direction indicated by the X-axis arrow in the figure, the loading device 2 includes a loading component 21 and a connecting component 22, the loading component 21 is provided with a accommodating hole 211, the connecting component 22 is passed through the accommodating hole 211 and connected to the loading component 21, the loading component 21 is configured to apply a load perpendicular to the first direction X to the connecting component 22, and the connecting component 22 is configured to be connected to the output end of the reducer 4; the load device 3 is connected to the side of the connecting component 22 away from the driving device 1.

[0049] In the first embodiment of the present application, a driving device 1 is provided to drive the reducer 4 to rotate, and a load device 3 connected to the output end of the reducer 4 through a connecting assembly 22 is used to make the reducer 4 bear torque during operation to simulate the actual operating conditions; the output end of the reducer 4 is connected to the loading assembly 21 through the connecting assembly 22 so that the loading assembly 21 can make the reducer 4 bear radial force during operation to simulate the actual operating conditions. In this embodiment, the connecting assembly 22 is inserted into the receiving hole 211 of the loading assembly 21 to limit the connecting assembly 22. Even if the loading assembly 21 outputs a large load, the connecting assembly 22 inserted into the receiving hole 211 will not be separated from the loading assembly 21 and maintain a relatively tight connection state, so that the reducer 4 test equipment can apply a large radial force to the reducer 4 during the test.

[0050] In some embodiments, the driving device 1 is connected to the input end of the reducer 4 via a universal coupling to eliminate the influence of the radial force received by the reducer 4 on the connection between the driving device 1 and the reducer 4 .

[0051] In some embodiments, a sensor is provided between the universal coupling and the input end of the reducer 4 to detect torque and rotation speed.

[0052] In some embodiments, the input end of the reducer 4 is connected to the driving device 1 through a spline and transmits torque.

[0053] In some embodiments, the reducer 4 test equipment further includes a reducer 4 bracket connected to the reducer 4 to support the reducer 4 in a direction perpendicular to the first direction X. Specifically, the reducer 4 bracket is used to support the reducer 4 in a direction perpendicular to the horizontal plane.

[0054] In some embodiments, see Figure 2-Figure 6 , Figure 2This is an oblique view of the loading device 2 in the reducer 4 test equipment provided in the embodiment of the present application, Figure 3 A top view of a loading device 2 in a reducer 4 test device provided in an embodiment of the present application, Figure 4 This is a front view of the loading device 2 in the reducer 4 test equipment provided in the embodiment of the present application. Figure 5 for Figure 3 The cross-sectional view at AA in the middle. Figure 6 An oblique view of the connecting component 22 in the reducer 4 test equipment provided in an embodiment of the present application, wherein the connecting component 22 includes a bearing member 221 and a plurality of connecting members 222, wherein the bearing member 221 is passed through the accommodating hole 211 and is connected to the loading component 21; one connecting member 222 is connected to a side of the bearing member 221 close to the driving device 1, and is configured to be connected to an output end of the reducer 4; and another connecting member 222 is connected to a side of the bearing member 221 away from the driving device 1, and is configured to be connected to the load device 3.

[0055] In some embodiments, please refer again to Figure 6 The connecting component 22 includes two connecting members 222, which are respectively connected to both sides of the bearing member 221 along the first direction X, wherein one connecting member 222 is used to connect to the output end of the reducer 4, and the other connecting member 222 is used to connect to the load device 3.

[0056] In other embodiments, the connecting assembly 22 includes only one connecting member 222, which is connected to the side of the supporting member 221 close to the driving device 1. The connecting member 222 is used to connect the output end of the reducer 4, and the load device 3 is connected to the side of the supporting device away from the driving device 1, so that the output end of the reducer 4 is directly subjected to torque.

[0057] In some other embodiments, the output end of the reducer 4 and the load device 3 are directly connected to two sides of the bearing member 221 along the first direction X respectively.

[0058] In the above embodiment with the connecting member 222, the connecting assembly 22 is divided into the bearing member 221 and the connecting member 222, so that when the model of the reducer 4 or the model of the load device 3 is changed, only the corresponding connecting member 222 needs to be changed to continue to use the loading device 2, thereby improving the applicability of the loading device 2. In addition, by arranging the bearing member 221 in the receiving hole 211, the bearing member 221 will not be separated from the loading assembly 21 when the loading device 2 applies a load.

[0059] In some embodiments, see Figure 11-13 , Fig.11 This is an oblique view of the connecting member 222 in the reducer 4 test equipment provided in the embodiment of the present application, Fig.12 This is a front view of the connector 222 in the reducer 4 test equipment provided in the embodiment of the present application. Fig.13 This is a cross-sectional view of a connector 222 in a test device for a reducer 4 provided in an embodiment of the present application. The connector 222 has a receiving cavity 2221 , a portion of the reducer 4 is disposed in the receiving cavity 2221 of one connector 222 , and a portion of the load device 3 is disposed in the receiving cavity 2221 of another connector 222 .

[0060] In the above embodiment, by arranging part of the reducer 4 and part of the load device 3 in the accommodating cavity 2221 of the connecting piece 222, the size of the reducer 4 test equipment in the first direction X can be shortened, so that the outer size of the reducer 4 test equipment is smaller and easier to install.

[0061] In some embodiments, see Figure 7-Figure 10 , Figure 7 This is an oblique view of the bearing member 221 in the reducer 4 test equipment provided in the embodiment of the present application, Figure 8 This is a side view of the bearing member 221 in the reducer 4 test equipment provided in the embodiment of the present application. Fig. 9 This is a front view of the bearing member 221 in the reducer 4 test equipment provided in the embodiment of the present application. Fig.10 for Figure 8 In the cross-sectional view at BB, the supporting member 221 includes a first connecting portion 2211 and a second connecting portion 2212, one connecting portion 222 is connected to a side of the first connecting portion 2211 close to the driving device 1, and is configured to be connected to the output end of the reducer 4; the other connecting portion 222 is connected to a side of the second connecting portion 2212 away from the driving device 1, and is configured to be connected to the load device 3.

[0062] It is understandable that the outer dimension of the bearing member 221 perpendicular to the first direction X may be greater than or equal to the inner diameter of the receiving hole 211, that is, the bearing member 221 may not be installed by directly passing through the receiving hole 211 and then axially limiting it.

[0063] In the above embodiment, the support member 221 is divided into a first connection portion 2211 and a second connection portion 2212 to facilitate the installation of the support member 221. That is, the support member 221 can be inserted into the accommodating hole 211 by simply passing a portion of the first connection portion 2211 or a portion of the second connection portion 2212 through the accommodating hole 211 and then connecting them to each other.

[0064] Further, in some embodiments, please refer again to Fig.10The first connection part 2211 is provided with a plurality of first through holes along the circumferential direction, and the second connection part 2212 is provided with a plurality of second through holes along the circumferential direction, and the first through holes correspond to the second through holes. The supporting member 221 also includes a plurality of first fasteners 2214, and the plurality of first fasteners 2214 are simultaneously penetrated through the first through holes and the second through holes to connect the first connection part 2211 and the second connection part 2212.

[0065] In some embodiments, please refer again to Fig.10 The first fastener 2214 may be a threaded fastener, such as a stud, which is inserted into the first through hole and the second through hole. The carrier also includes a plurality of nuts, which are threadedly connected to both ends of the stud.

[0066] In some embodiments, please refer again to Figure 6 , and 7, Fig. 9 and Fig.10 The carrier 221 has a positioning groove 2213 arranged along the circumferential direction. Part of the first connection portion 2211 and part of the second connection portion 2212 form the positioning groove 2213 , and part of the loading assembly 21 is embedded in the positioning groove 2213 .

[0067] It is understandable that the bearing member 221 may generate axial movement when rotating in the receiving hole 211 , and the axial movement may affect the test result.

[0068] In the above embodiment, the positioning groove 2213 is provided so that the bearing member 221 can be axially limited in the receiving hole 211, thereby preventing the bearing member 221 from axially moving when rotating in the receiving hole 211. The relative groove walls of the positioning groove 2213 are connected to a part of the loading assembly 21 to limit the bearing member 221 in the axial direction, that is, a part of the loading assembly 21 is clamped in the positioning groove 2213 to limit the bearing member 221 in the axial direction. In addition, the positioning groove 2213 is surrounded by a part of the first connecting portion 2211 and a part of the connecting portion to form the positioning groove 2213, which can facilitate the installation of the bearing member 221 in the receiving hole 211. For details, please refer to Fig.10 The two opposite groove walls for surrounding the positioning groove 2213 are respectively located at the first connecting portion 2211 and the second connecting portion 2212, so that the loading assembly 21 is clamped between the two opposite groove walls after the first connecting portion 2211 and the second connecting portion 2212 are connected.

[0069] In some embodiments, please refer again to Figure 5The loading assembly 21 includes a first clamping portion 212, a second clamping portion 213 and a first power portion 214. The second clamping portion 213 is connected to the first clamping portion 212 in a direction perpendicular to the first direction X. The first clamping portion 212 and the second clamping portion 213 form a receiving hole 211. The first power portion 214 is connected to the second clamping portion 213 to apply a load perpendicular to the first direction X to the second clamping portion 213.

[0070] It is understandable that the outer dimension of the bearing member 221 perpendicular to the first direction X may be greater than or equal to the inner diameter of the receiving hole 211, that is, the bearing member 221 may not be installed by directly passing through the receiving hole 211 and then axially limiting it.

[0071] In the above embodiment, the accommodating hole 211 is surrounded by two parts, namely the first clamping portion 212 and the second clamping portion 213, so that the support member 221 does not need to be installed by passing through the accommodating hole 211. Instead, the support member 221 only needs to be connected to one of the first clamping portion 212 and the second clamping portion 213, and then the other of the first clamping portion 212 and the second clamping portion 213 is connected to the first clamping portion 212 or the second clamping portion 213 to complete the installation of the support member 221.

[0072] In some embodiments, the first power unit 214 is a hydraulic cylinder to provide a radial load.

[0073] In other embodiments, the clamping assembly further includes a base 216, and the first power unit 214 is connected to the base 216 via a pad; in other embodiments, the base 216 is connected to the ground via high-strength bolts.

[0074] In some embodiments, please refer again to Figure 5 The loading assembly 21 further includes a bearing member 215 , which is disposed in the receiving hole 211 and connected to the first clamping portion 212 and the second clamping portion 213 , respectively. The connecting assembly 22 is passed through the bearing member 215 .

[0075] In the above embodiment, the bearing member 215 is provided to reduce the friction between the bearing member 221 and the loading device 2, so that the torque detection result is more accurate.

[0076] It is understandable that the bearing can be embedded in the positioning groove 2213, and the bearing can also play an axial limiting role on the bearing member 221.

[0077] In some embodiments, please refer again to Figure 5 and Figure 6 , the minimum dimension of the connecting member 222 along the direction perpendicular to the first direction X is greater than the minimum dimension of the supporting member 221 along the direction perpendicular to the first direction X.

[0078] It is understandable that the larger the size of the bearing member 215, the higher the purchase cost of the bearing member 215. By further reducing the radial size of the bearing member 221, the loading assembly 21 can select a bearing member 215 with a smaller inner diameter, thereby reducing the manufacturing cost of the equipment. In addition, the radial size of the connecting member 222 is larger than the minimum radial size of the bearing member 221, which can also enable the connecting member 222 to withstand a larger radial load, so that the test range of the reducer 4 test equipment is larger.

[0079] In some embodiments, please refer again to Fig.11 , Fig.12 and Fig.13 The connecting member 222 includes a main body 2222 and a first reinforcement member 2223, one end of the main body 2222 along the first direction X is configured to be connected to the bearing member 221, and the other end of the main body 2222 along the first direction X is configured to be connected to the reducer 4 or the load device 3; a plurality of first reinforcement members 2223 are arranged on the outer wall of the main body 2222 at circumferential intervals along the main body 2222, and the first reinforcement members 2223 extend along the first direction X.

[0080] In the above embodiment, the first reinforcement member 2223 is provided to enhance the bending resistance of the body 2222, so as to prevent the connection member 222 from bending when radial loading is performed. In order to obtain better bending resistance, the first reinforcement member 2223 also extends in the radial direction of the body 2222. Specifically, the center plane of the first reinforcement member 2223 is located on the plane formed by the radial direction of the body 2222 and the first direction X.

[0081] In some embodiments, please refer again to Fig.11 , Fig.12 and Fig.13 The connecting member 222 further includes a plurality of second reinforcement members 2224 , each second reinforcement member 2224 being connected between two adjacent first reinforcement members 2223 .

[0082] Furthermore, the outer walls of the plurality of connecting members 222 are located on the same cylindrical surface, and the cylindrical surface is coaxial with the outer wall of the body 2222. In some embodiments, the second reinforcing member 2224 is connected to the first reinforcing member 2223 by welding.

[0083] In the above embodiment, the second reinforcement member 2224 is provided to enhance the torsion resistance of the main body 2222 , thereby preventing the connection member 222 from deforming when torque loading is performed.

[0084] In some embodiments, the connecting member 222 has a weight-reducing groove 2225 , and the second reinforcing member 2224 and the main body 2222 are used to enclose the weight-reducing groove 2225 .

[0085] It is understandable that the weight of the connecting member 222 will affect the loading of the torque. In order to reduce the weight of the connecting member 222, a weight reducing groove 2225 is provided between the main body 2222 and the second reinforcement 2224 to reduce the weight of the connecting member 222, thereby reducing the influence of the weight of the connecting member 222 on the test structure.

[0086] In some embodiments, please refer again to Figure 1 The load device 3 includes a test gearbox 31 and a second power unit 32 . The output end of the test gearbox 31 is connected to an end of the connecting component 22 away from the driving device 1 , and the second power unit 32 is connected to the input end of the test gearbox 31 .

[0087] In the above embodiment, the second power unit 32 is provided to apply torque to the reducer 4, and the accompanying test gearbox 31 is provided to amplify the torque applied to the reducer 4. In order to achieve the effect of amplifying the torque, the accompanying test gearbox 31 is an accompanying test reduction box to achieve the purpose of deceleration and torque increase.

[0088] The above is a detailed introduction to a reducer 4 test equipment provided in an embodiment of the present application. Specific examples are used in the present application to illustrate the principles and implementation methods of the present application.
