Description

Technical Field

[0001] This utility model relates to the field of testing equipment technology, and more specifically, to a geared motor life testing device. Background Technology

[0002] Gear motors, as devices that convert electrical energy into mechanical energy, are widely used in various industries, and their application in the solar energy field is also very widespread. In order to understand the performance of gear motors, it is usually necessary to conduct life tests on them. Among them, life tests are generally sampling tests, which adopt random sampling and batch processing detection methods, and through batch data analysis, obtain more accurate and more valuable test results, making the test results more representative.

[0003] Conventional geared motor life testing devices include a worktable for supporting the geared motor, on which a load simulation component is fixed for movably connecting to the output shaft of the geared motor. By running under load for a long time, the lifespan of the geared motor is tested. For example, Chinese Utility Model Patent Publication No. CN202220530372.5 discloses a geared motor life testing device, which includes a worktable, a reducer, a spindle, two photoelectric switches, and a load simulation component. The spindle is equipped with two trigger heads, and the two photoelectric switches are respectively positioned opposite the two trigger heads. The two trigger heads rotate with the spindle and sequentially block the two photoelectric switches, giving signals to the motor under test, thereby frequently switching the rotation direction of the motor under test to simulate the actual use of the motor and effectively improve the accuracy of the test.

[0004] However, in actual use, the geared motors used in AGV vehicles, solar power generation equipment, and other equipment often change their rotation direction and load size frequently, and the running time under different loads is also different. The above-disclosed technical solutions only perform clockwise and counterclockwise alternating cycle tests on the geared motor, which does not truly simulate the load changes and running time changes under different loads in actual use. Therefore, the test results cannot truly reflect the lifespan of the geared motor. Therefore, a new solution is proposed: a geared motor lifespan testing device, as a further improvement. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a geared motor life testing device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a geared motor life testing device, comprising a workbench, a load geared motor, and a geared motor under test, wherein the testing device further comprises: a torque sensor and an input transition seat;

[0007] The torque sensor, input transition seat, and load reduction motor are all mounted on the workbench. The reduction motor under test is fixedly mounted on one end of the input transition seat. The output shaft of the reduction motor under test is fixedly connected to the input end of the input transition seat. The output end of the input transition seat is fixedly connected to the input end of the torque sensor through a first coupling. The output end of the torque sensor is fixedly connected to the rotating shaft of the load reduction motor through a second coupling.

[0008] Furthermore, the testing device also includes: a load-bearing geared motor bracket.

[0009] The bottom of the load reduction motor bracket is fixedly mounted on the workbench, and one end of the load reduction motor is fixedly mounted on the side of the load reduction motor bracket away from the torque sensor.

[0010] Furthermore, the testing device also includes: a torque sensor bracket,

[0011] The bottom of the torque sensor bracket is fixedly mounted on the workbench, and the bottom of the torque sensor is fixedly mounted on the top of the torque sensor bracket.

[0012] Furthermore, the testing device also includes: an input transition seat bracket.

[0013] The bottom of the input transition seat bracket is fixedly mounted on the workbench, and the bottom of the input transition seat is fixedly mounted on the top of the input transition seat bracket.

[0014] Furthermore, the center line of the output shaft of the tested geared motor, the center line of the first coupling, the center line of the second coupling, and the center line of the rotating shaft of the load geared motor all coincide.

[0015] The technical effects and advantages of this utility model are as follows:

[0016] 1. Compared with existing technologies, by setting up a load geared motor, since the geared motor under test is fixed on the input transition seat, the geared motor under test provides power, and a load geared motor is set at the end as a load, the load torque provided by the load geared motor is fully utilized, thereby simulating the working environment of a conventional geared motor, which facilitates the testing of its lifespan after long-term operation; moreover, the load size can be changed, which is convenient for testing various loads.

[0017] 2. Compared with existing technologies, by setting up a torque sensor, information such as the load torque of the load geared motor, the rotation direction of the geared motor under test, and the running time of the geared motor under test are converted into signals and fed back to the control system in real time. In this way, by regularly switching the rotation direction of the geared motor under test, changing the load torque provided by the load geared motor, and monitoring the running time of the geared motor under test, the actual use of a conventional geared motor can be simulated, effectively improving the accuracy of testing the geared motor under test.

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0028] As attached Figure 1 The device shown is a geared motor life testing device, which includes a workbench 1, a load geared motor 2 and a geared motor under test 3. The testing device also includes a torque sensor 4 and an input transition seat 5.

[0029] The torque sensor 4, the input transition seat 5, and the load reduction motor 2 are all mounted on the worktable 1.

[0030] The geared motor 3 under test is fixedly installed at one end of the input transition seat 5.

[0031] The output shaft of the geared motor 3 under test is fixedly connected to the input end of the input transition seat 5.

[0032] The output end of the input transition seat 5 is fixedly connected to the input end of the torque sensor 4 via the first coupling 6.

[0033] The output end of the torque sensor 4 is fixedly connected to the rotating shaft of the load reduction motor 2 via the second coupling 7.

[0034] Among them, the tested geared motor 3 drives the output end of the input transition seat 5 to rotate and drives the torque sensor 4 and the rotating shaft of the load geared motor 2 to rotate.

[0035] The control system inside the testing device is electrically connected to the torque sensor 4, the load geared motor 2, and the geared motor under test 3, respectively. The torque sensor 4 transmits the measured data signal to the control system, while the load geared motor 2 and the geared motor under test 3 receive the control signal provided by the system.

[0036] In this process, the test geared motor 3 is fixed to the input transition seat 5, the test geared motor 3 provides power, and the load geared motor 2 is set at the end as a load to simulate the working environment of a conventional geared motor, so as to facilitate the testing of its lifespan after long-term operation.

[0037] By setting a torque sensor 4, information such as the load torque of the load reduction motor 2, the rotation direction of the tested reduction motor 3, and the running time of the tested reduction motor 3 are converted into signals and fed back to the control system in real time. In this way, by regularly switching the rotation direction of the tested reduction motor 3, changing the load torque provided by the load reduction motor 2, and monitoring the running time of the tested reduction motor 3, the actual usage conditions of a conventional reduction motor can be simulated, effectively improving the accuracy of testing the tested reduction motor 3.

[0038] In a preferred embodiment, as shown in the appendix Figure 1 As shown, the testing device also includes: a load geared motor bracket 21.

[0039] The bottom of the load reduction motor bracket 21 is fixedly installed on the workbench 1, and one end of the load reduction motor 2 is fixedly installed on the side of the load reduction motor bracket 21 away from the torque sensor 4, so as to fix the load reduction motor 2 using the load reduction motor bracket 21.

[0040] In a preferred embodiment, as shown in the appendix Figure 1 As shown, the testing device also includes: a torque sensor bracket 41.

[0041] The bottom of the torque sensor bracket 41 is fixedly mounted on the workbench 1, and the bottom of the torque sensor 4 is fixedly mounted on the top of the torque sensor bracket 41, so that the torque sensor 4 can be fixed by the torque sensor bracket 41.

[0042] In a preferred embodiment, as shown in the appendix Figure 1 As shown, the testing device also includes: an input transition seat bracket 51.

[0043] The bottom of the input transition seat bracket 51 is fixedly installed on the workbench 1, and the bottom of the input transition seat 5 is fixedly installed on the top of the input transition seat bracket 51; so as to use the input transition seat bracket 51 to fix the input transition seat 5 and the geared motor 3 under test.

[0044] In a preferred embodiment, as shown in the appendix Figure 1 As shown, the center line of the output shaft of the tested geared motor 3, the center line of the first coupling 6, the center line of the second coupling 7, and the center line of the rotating shaft of the load geared motor 2 all coincide; so that when the output shaft of the tested geared motor 3 drives the torque sensor 4 and the rotating shaft of the load geared motor 2 to rotate, the resistance encountered is reduced.

[0045] The working principle of this utility model is as follows: When working, the geared motor 3 to be tested is first fixed on the input transition seat 5, thereby driving the torque sensor 4 and the rotating shaft of the load geared motor 2 to rotate. Then, the torque sensor 4 transmits the measured load torque magnitude, rotation direction and running time signals to the control system.

[0046] Finally, the test system controls the running time and rotation direction of the tested geared motor 3 and changes the load torque of the load geared motor 2 to simulate the actual use of a conventional geared motor, thereby effectively improving the accuracy of the test.
