Experiments can accurately test performance parameters such as transmission torque and efficiency of transmission components, significantly improving the understanding of mechanical transmission systems among university students majoring in equipment manufacturing. However, traditional mechanical transmission efficiency test benches can only perform single-function performance testing. If different transmission systems need to be tested, different test benches must be set up, which not only increases experimental costs but also reduces experimental efficiency.

[0003] Therefore, there is an urgent need for a mechanical transmission performance testing platform to meet the requirements for performance testing of different transmission systems. Utility Model Content

The third slide rail is arranged perpendicular to the boundary line between the first test area and the second test area. The third moving platform is connected to the third slide rail, and the third driving mechanism is used to drive the third moving platform to slide along the third slide rail.

[0011] Preferably, the first drive mechanism, the second drive mechanism, and the third drive mechanism each include a rack, a drive shaft, and a handwheel. The drive shaft is vertically arranged, and a gear that meshes with the rack is provided at the end of the drive shaft. The handwheel is used to drive the drive shaft to rotate.

[0012] Preferably, a protective housing is provided around the rack, the protective housing being used to form a cavity structure for containing lubricating grease.

[0013] Preferably, the protective housing and the experimental platform, as well as the protective housing and the first mobile platform, are detachably connected.

[0026] The present invention will now be described in detail with reference to the accompanying drawings.

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0028] Therefore, the following detailed description of the embodiments of this utility model is not intended to limit the scope of the claimed utility model, but merely to illustrate some embodiments of the utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0029] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0030] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0031] In the description of this utility model, it should be noted that the terms "upper," "lower," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product is in use, or the orientation or positional relationship commonly understood by those skilled in the art. These terms are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this utility model. In addition, the terms "first," "second," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0032] Example 1: As Figure 1 and Figure 2 As shown, the mechanical transmission performance testing platform for rapid switching of the test object according to this utility model includes a test platform, which is divided into a first test area and a second test area along its length. The first test area is provided with a first test module for testing input transmission performance, and the second test area is provided with a second test module for testing output transmission performance.

[0033] The first test area is provided with a first mobile platform and a second mobile platform, and the first test module is provided on the second mobile platform;

[0034] The first test area is also provided with a first slide rail and a first drive mechanism. The first slide rail is set parallel to the boundary line between the first test area and the second test area. The first moving platform is connected to the first slide rail, and the first drive mechanism is used to drive the first moving platform to slide along the first slide rail.

[0035] The surface of the first mobile platform is provided with a second slide rail and a second drive mechanism. The second slide rail is set perpendicular to the first slide rail. The second mobile platform is connected to the second slide rail. The second drive mechanism is used to drive the second mobile platform to slide along the second slide rail.

[0036] The mechanical transmission performance testing platform for rapid switching of the test object described in this invention uses the first driving mechanism and the second driving mechanism to drive the first moving platform and the second moving platform to move respectively, so that the first test module and the second test module can form a coaxial connection or a horizontally misaligned connection, thereby realizing rapid switching of performance testing of different transmission systems, reducing experimental costs and improving experimental efficiency.

[0037] Specifically, in this embodiment, the first test module includes a bearing housing and an input torque sensor; the second test module includes a magnetic powder loader and an output torque sensor; in this embodiment, by setting the first test module and the second test module, the performance parameters such as the transmission torque and transmission efficiency of the transmission components can be detected.

[0038] When the first test module and the second test module are coaxially connected, the transmission path of the transmission system is: stepper motor → input torque sensor → bearing housing → output torque sensor → magnetic powder loader;

[0039] When the first test module and the second test module are horizontally misaligned, the transmission path one of the transmission system is: stepper motor → input torque sensor → bearing housing → transmission belt → output torque sensor → magnetic powder loader; the transmission path two of the transmission system is: stepper motor → input torque sensor → bearing housing → chain drive → output torque sensor → magnetic powder loader.

[0040] Furthermore, after simple disassembly and reassembly, the experimental platform of this novel invention can be assembled into a motor performance testing device, with the transmission path being: stepper motor → output torque sensor → magnetic powder loader.

[0041] In a preferred embodiment, based on the above method, the surface of the second test area is further provided with a third moving platform, a third slide rail and a third driving mechanism. The third slide rail is arranged perpendicular to the boundary line between the first test area and the second test area. The third moving platform is connected to the third slide rail, and the third driving mechanism is used to drive the third moving platform to slide along the third slide rail.

[0042] In this embodiment, by adjusting the relative position of the third moving platform to the third slide rail, it can adapt to test objects of different sizes or types when performing transmission efficiency tests and motor performance tests. This improves the versatility and flexibility of this novel experimental platform.

[0043] Example 2: As Figures 1 to 3 As shown, this utility model describes a mechanical transmission performance testing platform for rapidly switching between test objects.

[0044] In a preferred embodiment, based on the above method, the first driving mechanism, the second driving mechanism and the third driving mechanism each include a rack, a transmission shaft and a handwheel. The transmission shaft is vertically arranged, and a gear that meshes with the rack is provided at the end of the transmission shaft. The handwheel is used to drive the transmission shaft to rotate.

[0045] Specifically, in this embodiment, the first, second, and third moving platforms are equipped with connecting bearings, and the drive shaft passes through the connecting bearings; the handwheel is provided with anti-slip texture to increase friction and facilitate user rotation of the handwheel. The drive shaft and the gear are connected by a key to ensure the stability and reliability of the transmission. Limit blocks are provided at both ends of the rack to prevent the first, second, and third moving platforms from exceeding a predetermined range during movement.

[0046] In this embodiment, the driving structure is set to the cooperation of the gear and the rack. After the positions of the first moving platform, the second moving platform and the third moving platform are adjusted to the correct positions, accidental slippage can be avoided, thus ensuring the stability and accuracy of the experiment.

[0047] In a preferred embodiment, based on the above method, a protective shell is further provided around the rack, which forms a cavity structure for containing lubricating grease. This structural arrangement can improve the service life of the rack; simultaneously, injecting lubricating grease into the protective shell can reduce the coefficient of friction between the rack and gears, making the drive smoother. Furthermore, the protective shell can prevent external impurities and contaminants from entering the mating parts of the rack and gears, maintaining the cleanliness of the lubricating grease and further improving the stability and reliability of the transmission.

[0048] As a preferred embodiment, based on the above method, the protective shell and the experimental platform, as well as the protective shell and the first mobile platform, are detachably connected.

[0049] Specifically, in this embodiment, the protective housing is bolted to the experimental platform and the first moving platform. This structural design facilitates the cleaning of expired grease and the repair and replacement of the protective housing if damaged, further improving the practicality of this invention in actual use.

[0050] As a preferred embodiment, based on the above method, a sealing rubber is further provided at the bottom of the protective shell. This structural design prevents grease from leaking from the bottom of the protective shell, thus avoiding contamination of the experimental platform and ensuring sufficient grease reserves, thereby improving lubrication performance.

[0051] In a preferred embodiment, based on the above method, a scraper is further provided inside the protective housing. The width of the scraper matches the width of the tooth surface of the rack, and the length of the scraper is at least half the length of the rack. A slider is provided at the end of the protective housing, and the slider can slide along the end face of the protective housing. The scraper is connected to the slider.

[0052] In this embodiment, it is considered that when the test bench is not used for a long time, the grease will accumulate at the bottom of the protective housing, resulting in insufficient grease on the rack and affecting the lubrication effect. At this time, the slider can be moved to move the scraper towards the rack, so that the grease at the bottom of the protective housing gathers towards the tooth surface of the rack. In this way, the grease can be applied to the rack, ensuring the lubrication effect between the rack and the gear, thereby extending the service life of the rack and improving the stability and reliability of the transmission. Furthermore, when the test bench is stored, moving the scraper to make it fit against the rack can also ensure that the rack is fully coated with grease, thus greatly reducing the risk of oxidation and corrosion of the rack, further extending the service life of the rack.

[0053] Example 3: As Figure 1 and Figure 2 As shown, the mechanical transmission performance testing platform for rapid switching of the test object of this utility model, based on the above method, further includes a planetary reducer between the first test module and the second test module, and the planetary reducer is connected to the test platform.

[0054] This structural design allows for speed reduction transmission testing of the transmission components, broadening the functionality and applicability of this novel experimental platform. Furthermore, the planetary reducer is positioned between the first and second test modules, allowing for selection of whether to use it for transmission based on actual testing needs, thus further enhancing the versatility and flexibility of this novel experimental platform.

[0055] As a preferred embodiment, based on the above method, the experimental platform is further provided with a lifting ring; the lifting ring and the experimental platform are detachably connected.

[0056] Specifically, in this embodiment, the lifting ring and the experimental platform are connected by bolts. This structural design improves the ease of moving the novel experimental platform.

[0057] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
