WZ Taxanaha Birta ah ee fadhiya OS&Y albaabka albaabka
Sharaxaad:
WZ Taxanaha Birta ah ee fadhiya OS&Y albaabka albaabka adeegsada irid birta ductile ka soo saarta oo leh faraanti naxaas ah si loo hubiyo shaabad aan biyuhu lahayn. Waalka albaabka OS&Y (Dibadda Screw iyo Harqood) waxaa inta badan loo adeegsadaa nidaamyada rusheeyaha dabka. Farqiga ugu weyn ee NRS-ta caadiga ah (Non Rising Stem) albaabka albaabka waa in jirridda iyo lawska la dhigo meel ka baxsan jirka waalka. Tani waxay sahlaysaa in la arko in uu furn yahay ama xiran yahay, maadaama ku dhawaad dhammaan dhererka jirku uu muuqanayo marka uu furmo, halka jirku uusan hadda muuqan marka uu xirmo. Guud ahaan tani waa shuruudo ka mid ah nidaamyada noocan oo kale ah si loo xaqiijiyo xakamaynta muuqaal degdeg ah ee heerka nidaamka

Tilmaam:
Nuska wedge: lowska naxaasta ah waxa uu ka samaysan yahay daawaha naxaasta oo leh awoodo saliidayn ah oo siinaya waafaqid ugu wanagsan ee asmada birta ah.
Wedge: Xarkadu waxay ka samaysan tahay bir bir ah oo leh giraangiyo weji daawaha naxaas ah kuwaas oo lagu farsameeyay dhamaystirka dusha sare ee wanaagsan si loo hubiyo xidhidhiyaha xidhiidhka ugu fiican ee leh faraantiyada kursiga jidhka. Jeexdintu waxay xaqiijisaa xidhidh isku mid ah iyadoon loo eegin cadaadiska sare. si buuxda u ilaalinaya dahaarka ah ee epoxy fusion bonded.
