Izinhlobo zemicu esetshenziselwa ubuchwepheshe

Intambo igoqa ngokumnandi nge-pitch ejwayelekile esetshenziselwa ukucubungula noma okuyi-cylindrical surface. Yisici esiyinhloko sokuxhuma kwezinhlobo ezimbili zokuqinisa, kanye nezinsimbi ze-helic and gear-helical. Imikhawulo esemqoka yentambo yezibopho zanamuhla ichazwa ku-GOST 11708-82: lena yi- pitch intambo emkhatsini wezinguquko eziseduze, izingxenye zangaphandle nezangaphakathi ze-fastener element, i-angle ye-top of the turn turn.

Izinhlobo zezintambo kwi-fasteners zihlukaniswe zibe:

• Amaphakathi - asetshenziselwa amantongomane, imikhonto yamahange, ama-couplings, amapayipi;
• Ngaphandle - itholakala ku-screws, screws, screws, bolts, stiletto izithende.

Kukhona izinhlobo ezilandelayo zezintambo ngokusho kwe-GOST:

• I-Metric - iphrofayili ngesimo se-triangle equilateral (kwenzeka ngezinyathelo ezincane, eziphakathi nezinkulu);
• Ukuma kwe-inch - triangular noma trapezoidal;
• I-Metric conical - inephrofayli engunxantathu;
• Ukuzungeza - ukunyakaza kwesimo sefomu nxazonke;
• I-Trapezoidal - ukuqhutshwa kwesigcawu sefomu le-trapezoidal;
• Iphrofayili ephikisiwe - trapezoidal asymmetric;
• I-modular - iphrofayili efana nomdwebo we-trapezoid;
• I-tubular conical and cylindrical (iphrofayili inesimo sesigxathu se-isosceles se-inch isayizi nge-rounded (noma flattened) pepe kanye ne-coil crest);
• I-inch - iphrofayli ekhonjiwe ene-vertex enqunyiwe yesimo esingunxantathu.

Kukhona izinhlobo ezinjalo zemicu njengezikwele futhi ezixubile. Isetshenziselwa ukubopha izakhi ngokukhipha izikhonkwane ngokusho kwemidwebo ngayinye. Izinhlobonhlobo zezintambo azivumeli ukuthola ukunemba okucacile kakhulu, ngakho-ke akuvamile ukusetshenziswa. Awekho ama-GOST kuwo.

Kuze kube manje, ngezinhlelo zokusebenza jikelele zokwakha umshini, intambo enkulu yangaphandle neyangaphakathi iyimethrikhi. Emidwebo, kuboniswa yincwadi enkulu "M" ekhombisa ububanzi obungaphandle ngamamitha. Izinhlobo zeThubhu zemijondolo zisetshenziselwa ukuxhuma amapayipi ahlukahlukene. Ububanzi bawo obunamagama buyingxenye yangaphakathi yamapayipi angaphandle kwalapho intambo igawulwa khona. Emidwebo, kuboniswa yincwadi enkulu "G" ekhombisa ububanzi obungaphakathi ngaphakathi kwepayipi ngamasentimitha.

Izintambo eziyinhloko zohlobo lwazo zonke izinhlobo ziyi-reference reference. Zitholakala kunoma yikuphi ukuqondiswa komakhi womshini. Imininingwana yezintambo zokubhekisela imicu ichazwe ngokuningiliziwe ngokuhambisana ne-GOST 9150-81, 24705-81 no-8724-81. Ngezingxube ze-tube ezinama-cylindrical, ubukhulu bunikelwa ku-GOST 6357-81.

Enye yezintambo ezijwayelekile ezixhunyiwe nge-metric thread i-bolt. Kuyinto induku yensimbi enekhanda ekugcineni. Ubude benduku bukhonjiswe ngempango ye-helical. Inhloso yezibopho - ukuxhuma izingxenye ezihlukahlukene zezinhlelo nezakhiwo ezine-nut. Inhloko ye-bolt iyinhlanganisela engamakhilomitha ayisithupha (eyimfihlo, isisombululo, i-butt, mortgage, terminal).

Kunezinhlobo ezilandelayo ze-bolts ngenhloso:

• Ifenisha - ejwayele ukujoyina imikhiqizo ekukhiqizeni ifenisha;
• Ukwakhiwa kwemishini - isetshenziselwa imboni yokubaluleka kwezimboni;
• Lemeshnye - eyenzelwe ukuhlanganiswa kwemishini emkhakheni wezolimo;
• Road - isetshenziselwa ukuxhuma izakhiwo zensimbi ezihlukahlukene nezithiyo zomgwaqo.
