By the end of 2016, China railway operation of the total mileage of 124000 kilometers, of which 22000 km of high speed railway, the world's first, more than the rest of the world high-speed operation mileage combined. But hidden behind a brilliant achievement, with a Japanese company unknown - gerhard lok industrial co., LTD. Its products is very simple: never loose screws.
This is a company the product perfectly. It's never loose screw customers have covered the railway, aviation, aerospace, medical and other fields, and the range continues to expand. The hidden champion in a niche market, it is very worthy of our deep understanding.
High speed rail reaches more than 250 kilometers per hour, and domestic currently used the most advanced "Renaissance" trains, fastest speed can reach more than 350 kilometers per hour, with the first class of "land". For high-speed trains, each small parts have to undergo crucible under high speed environment, the screw is no exception. It is easy to understand, high-speed operation, high-speed trains and rail contact unceasingly, will impact the formation of strong vibration, tracks the ordinary screw in this kind of high strength and vibration, to avoid a bit, it will need often artificial check and tighten again, and this takes it's hard to imagine the manpower and financial resources.
If you want to avoid being shake shake loose to fly, you need to screw and nut interesting, never loose, however, the requirement of "never loose" seems very simple, but the actual is very complicated to do. With even a minimal understanding of the mechanical processing industry will know, if you want to do screw and nut "interesting", need to cooperate with highly sophisticated, both size precision to perfect, and the processing capacity of production of machine and put forward high request, not two "diamond", it is impossible to win this kind of "porcelain live".
