Cuntada lo'da, waxaa sidoo kale loo yaqaanaa quful qufulka ah, lowska qufulka leh, lowska qufulka leh, lowska xawaaraha adag leh, cunnada adag ee nafaqada leh, waa lowska ka hortimaada dabacsanaanta hoostiisa iyo gariirka. Nooca xawliga ah ee loo yaqaan 'Elastic Stop nuts' iyo walxaha xawaaraha ku socda ayaa ah nooc gaar ah halka qayb ka mid ah lowsku si xoog leh u gooyo si ay u bixiso ficil quful ah. Nooca ugu horreeya wuxuu isticmaalaa fiber halkii uu ku siin lahaa nylon waxaana la sameeyay sanadkii 1931.

Seddex faa iido oo nuts qufulan ah

Marka hore, waxqabadka ka-hortagga gariirka: Marka dunta ay adkeyso, dunta fiilada daboolka leh ee guntinta ayaa si adag u galeysa xajmiga 30 °-qaab-qaabeysan oo lowska ah waana la isku xiray. Xariiqdu waa xagal ay ka mid tahay 60 °, halkii ay ka ahaan lahayd xagal la soo koobay oo ah 30 °. Sidaa darteed, xoogga caadiga ah ee la sameeyo marka lowska qufulku adkeeyo ayaa aad uga badan kan lowska caadiga ah, wuxuuna leeyahay awood weyn oo uu kaga hortago jilicsanaanta iyo gariirka.

Second, wear resistance and shear resistance are strong: the 30 ° bevel of the thread of the nut thread can evenly distribute the nut's locking force on the threads of all the teeth. Because the pressing force on the thread surface of each tooth is evenly distributed, The nut can better solve the problems of thread wear and shear deformation.

Midda saddexaad, waxqabadka dib-u-adeegsiga: tiro aad u badan ayaa la adeegsanayaa waxay muujineysaa in qufulka qufulka lowska aan la yareyneyn ka dib soo noqnoqda isku-celinta iyo kala-baxa, iyo saameynta asalka ah ee qufulka ayaa la sii wadi karaa.
