Description

Technical Field

[0001] The utility model relates to the technical field of transmission chain detection, in particular to a transmission chain operation limit life detection experimental platform. Background Art

[0002] The transmission chain operation limit life detection experimental platform is a device used to test the life of the transmission chain. It simulates various working conditions in actual use, drives the chain to operate through a motor, applies different loads, speeds and other conditions to the chain, and continuously monitors the performance changes of the chain. With the development of industry, transmission chains are widely used in the mechanical field, and their reliability is extremely important. The platform can accurately evaluate the life of the chain in different environments, provide a basis for product design and quality control, ensure the safety and reliability of the chain in actual use, and reduce equipment downtime and production losses caused by chain failure.

[0003] Currently, most of the transmission chain rotation detection devices on the market are not easy to use, not easy to fix the two ends of the chain, and most of them can only perform vertical tension detection, but are not easy to perform rotation detection, and are not easy to adjust the detection point of the chain. Therefore, it is necessary to improve the current transmission chain rotation detection device;

[0004] The existing patent (publication number: CN214373329U) discloses a transmission chain rotation detection device, including a casing and a sprocket, wherein a detection platform is connected to one side of the casing, a first threaded rod is connected to the inside of the first connecting rod close to the guide rod, a second connecting rod is connected between the first threaded rod and the guide rod, and one end of the second connecting rod is connected to a connecting block. The transmission chain rotation detection device is provided with a first gear tooth and a second gear tooth. One end of the chain to be detected is inserted into the slot, and then one side of the chain is engaged with the first gear tooth. Then the cover plate is flipped through the second rotating shaft. The cover plate is flipped so that the square groove passes through the square block. At the same time, the second gear tooth on one side of the cover plate will engage with the other side of the chain. At this time, the square block is rotated to misalign the square block with the square groove. The rotation of the square block drives the thread sliding between the second threaded rod and the thread groove until the square block presses the cover plate and the connecting block tightly. In this way, the first gear tooth and the second gear tooth clamp both sides of the chain to be detected for easy fixation.

[0005] In response to the above problems, existing patents provide solutions. However, when testing the operation of the transmission chain, due to the lack of a structure for simulating experiments in different environments, it is impossible to simulate the chain in environments with and without lubricating oil respectively, which reduces the flexibility of the chain simulation experiment.

[0006] Therefore, an experimental platform for detecting the operating limit life of transmission chains is proposed. Utility Model Content
