Ingcaciso yeMveliso

IiNgcaciso eziQinisekileyo:I-ASME B 18.6.3 - 2013 iyahambelana neSlotted Close Tolerance 100-deg Flat Countersunk Head Screw (Izikrufu zoomatshini kuphela) zithobela imigangatho echanekileyo yobukhulu, iqinisekisa ukusebenza okungaguqukiyo kunye nokuhambelana namacandelo oomatshini. Uyilo lwabo olusondeleyo lokunyamezela lunciphisa ukuhluka, ukwandisa ukuthembeka kwizicelo ezibalulekileyo.

Ulwakhiwo olomeleleyo:Yenziwe kwi-ASTM F837 kunye ne-F468 inkcazo, ezi zikhonkwane ziqhayisa ulwakhiwo olomeleleyo olumelana noxinzelelo oluphezulu kunye nemithwalo ye-torque. Benzelwe ukuqina, bagqwesa kwiindawo ezibangwayo zemizi-mveliso, banikezela ukusebenza kwexesha elide ngaphandle kokubeka esichengeni ingqibelelo.

INdibano Esebenzayo:Ngoqwalaselo lwazo lwe-slotted drive, ezi zikrufu ziququzelela iinkqubo zendibano ezisebenzayo, ezivumela ukufakwa okukhawulezayo kunye nokungabikho kobunzima usebenzisa izixhobo eziqhelekileyo. Oku kulula ukusetyenziswa kunciphisa ixesha lokuphumla kunye neendleko zabasebenzi, ukwandisa imveliso kwimisebenzi yokuvelisa kunye nendibano.

Uluhlu olubanzi lwesicelo:Idizayinelwe usetyenziso lwezikrufu zomatshini, ezi zikrufu zifumana into eluncedo kuwo wonke amashishini ahlukeneyo, kubandakanya iimoto, i-aerospace, kunye nokuveliswa koomatshini. Ukuguquguquka kwazo kunye nokuthembeka kwazo kuzenza zibe zizinto eziyimfuneko ekukhuseleni nasekuqiniseni iindawo ezibalulekileyo kunye namalungu.
