Trenaren eremua

The railway is one of the most important inventions and means of transportation of mankind. For centuries, mankind has continued to innovate its technology, and the technology of railways and locomotives has not yet reached its peak.

Today, railways around the world have more transport responsibilities than ever before, and the demands placed on locomotive manufacturers and their suppliers are constantly changing. Shorter product cycles and technological innovation, the use of newer, more advanced, lighter, more energy-saving and environmentally friendly materials, and even the ever-changing division of labor require continuous innovation and adaptation.

Hari-harizko txertaketa, self-tapping thread insert and key locking insert are widely used in railways and locomotives as new and innovative fastening technologies. Abiadura handiko trenbideak bereziki azkar garatzen ari dira gurean, eta abiadura handiko EMUak herrialde osoko trenbide nagusi guztietan ari dira lanean eta hainbat herrialdetara esportatzen dira.. Aluminio-aleazioa lokomotora-unitateen material nagusia bihurtu da, zigilatzeko propietate arin eta onengatik. Hala ere, aluminio-aleazioko materialen izaera bigunak ebakidura-erresistentzia ahula eragiten du hariztutako konexioetan. Oinarrizko materialaren harien prozesamendu zuzenak ezin ditu trenbideko ibilgailuen muntaketa eta funtzionamenduaren segurtasun baldintzak bete. Aluminio aleazioak hari-zorroak erabiltzea eskatzen du konexioaren egonkortasuna eta fidagarritasuna bermatzeko.

Etxeko EMU mota ezberdinetan, hariztutako zorroak hainbat harizko konexio egituretan erabiltzen dira, hala nola ibilgailuen barnealdean, kanpoko esekidurak, and under-car hoisting. The main types include wire thread inserts, hari txertaketa auto-takatzaileak, and key locking thread inserts. The CRH1 EMU has a stainless steel body and does not require the use of threaded sheaths; the CRH2 EMU mainly uses steel wire threaded inserts; the CRH3 EMU mainly uses self-tapping threaded inserts, and is also used in some large-diameter pipe connections. Wire thread inserts are used in parts; key locking thread inserts are used in CRH5 EMUs.
