Description

Technical Field

[0001] This utility model relates to the field of motor testing equipment technology, and in particular to a motor torque testing device. Background Technology

[0002] As a key component that converts electrical energy into mechanical energy, the electric motor is widely used in many fields such as industrial automation, intelligent manufacturing, transportation, home appliances, and robotics, and is the core drive unit of modern electromechanical systems. The performance parameters of the motor directly affect the stability, efficiency, and reliability of equipment operation. Among them, output torque is a key indicator for measuring the driving force of the motor, which determines its load-carrying capacity, starting capability, and operating performance under different working conditions.

[0003] In practical applications, whether the output torque of a motor meets the design or rated requirements is a crucial basis for motor quality inspection, system integration selection, and operational safety. Especially in scenarios sensitive to load changes or requiring stable output (such as CNC machine tools, automated production lines, and lifting equipment), insufficient torque can lead to equipment malfunctions, frequent shutdowns, and even mechanical failures and safety accidents. Therefore, effectively testing motor torque is a key step in ensuring motor quality, assessing its service condition, and evaluating the overall reliability of the system.

[0004] Currently, common methods for testing motor torque mainly fall into two categories: one is indirect testing methods based on electrical parameters, such as indirectly calculating torque by measuring parameters like current, voltage, and speed, combined with a motor model; the other is direct measurement of motor output using torque sensors or loading devices. While these methods offer high testing accuracy, they often suffer from the following drawbacks: precision torque sensors, control systems, and their associated circuitry are expensive, making them unsuitable for large-scale use or application in resource-constrained environments; and the electrical parameter method relies on modeling and calculation, making it difficult for testers to directly observe and judge the results.

[0005] Therefore, there is an urgent need for a motor torque testing device that can solve the problem of a single line. Summary of the Invention

[0006] The purpose of this invention is to provide a motor torque testing device to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides a motor torque testing device, including a base, mounting holes at the four corners of the base, a bearing assembly on the base, the bearing assembly being fixedly mounted on the base by bolts, a motor mounting plate on one side of the base, a motor being fixedly mounted on the motor mounting plate, and a main drive shaft being fixedly connected to the output end of the motor by a motor bushing.

[0008] Preferably, a clutch sleeve is slidably connected to the other end of the drive shaft.

[0009] Preferably, a driven shaft is movably provided at the other end of the clutch sleeve.

[0010] Preferably, an eccentric disc is provided at the other end of the driven shaft.

[0011] Preferably, a fisheye shaft is fixedly mounted on the eccentric disc.

[0012] Preferably, a load is connected to the fisheye shaft.

[0013] Preferably, both the main drive shaft and the driven shaft have grooves at the ends near the clutch sleeve.

[0014] Therefore, the present invention employs the above-mentioned motor torque testing device, which has the following beneficial effects:

[0015] (1) The product has a simple structure and the motor is easy to replace. It can test 5 to 6 motors within 10 minutes. At the same time, the base has four mounting holes, which can be fixed on any plane.

[0016] (2) The design of the main and driven shafts and clutch sleeve makes disassembly and assembly more flexible when testing different motors or load conditions.

[0017] (3) If the motor drives the load to rotate, it means that its torque meets the standard. This method is simple and easy to implement, does not rely on complex electronic measurement methods, and the test method is more intuitive.

[0018] (4) Controllable linkage is achieved through the clutch sleeve, which makes it convenient to connect or disconnect load for testing; the fisheye shaft and eccentric disc design facilitates connection of different types of loads.

[0026] Example

[0027] like Figure 1-2 As shown, this utility model provides a motor torque testing device, including a base 1, mounting holes 2 at the four corners of the base 1, a bearing assembly 3 on the base 1, the bearing assembly 3 being fixedly mounted on the base by bolts, the bearing assembly 3 including multiple bearings, a motor mounting plate 4 on one side of the base 1, a motor fixedly mounted on the motor mounting plate 4, the output end of the motor being fixedly connected to a main drive shaft 6 via a motor bushing 5, a clutch sleeve 7 being slidably connected to the other end of the main drive shaft 6, a driven shaft 8 being movably mounted inside the clutch sleeve 7, an eccentric disc 9 being mounted on the other end of the driven shaft 8, a fisheye shaft rod 10 being fixedly mounted on the eccentric disc 9, and a load being connected to the fisheye shaft rod 10.

[0028] In this embodiment, grooves 11 are provided on both the main drive shaft 6 and the driven shaft 8 near the clutch sleeve 7, thereby ensuring that the clutch sleeve can slide and be fixed between the main drive shaft 6 and the driven shaft 8. The bearing assembly 3 is sleeved on the outer wall of the main drive shaft 6 and the driven shaft 8.

[0029] A motor torque testing device is used to confirm whether the motor torque meets the rated requirements. Specifically, the device determines whether the motor torque meets the standard based on whether the load drives the motor to rotate.

[0030] The specific connection methods of each part all adopt conventional methods such as bolts, rivets, and welding that are mature in existing technology. The machinery, parts and equipment all adopt conventional models in existing technology. In addition, the circuit connection adopts conventional connection methods in existing technology, which will not be described in detail here.

[0031] In this embodiment, the motor torque testing device is used with the motor fixed on the motor mounting plate 4 and connected to the main drive shaft 6 via the motor bushing 5. The sliding clutch sleeve 7 connects the main drive shaft 6 and the driven shaft 8, allowing for normal operation. The fisheye shaft rod 10 can connect to a load, the weight of which is the theoretical weight that the motor torque can withstand, calculated from the specifications. After the motor starts, the motor bushing 5 drives the main drive shaft 6 to rotate. Since the sliding clutch sleeve 7 connects the main drive shaft 6 and the driven shaft 8, force is transmitted from the main drive shaft 6 to the driven shaft 8. Then, the rotational motion is applied to the load through the eccentric disc 9 and the fisheye shaft rod 10. If the motor can drive the load to rotate normally, it indicates that the motor torque meets the rated requirements.

[0032] Therefore, the present invention adopts the above-mentioned motor torque testing device, which has a simple product structure, is easy to replace motors, and can test 5 to 6 motors within 10 minutes. At the same time, the base has four mounting holes, which can be fixed on any plane.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the technical solutions of the present invention, and these modifications or equivalent substitutions cannot cause the modified technical solutions to deviate from the spirit and scope of the technical solutions of the present invention.
