Iqukethe izikhangisoUkuthenga ngaphakathi nohlelo

Mayelana nalolu hlelo lokusebenza

Izici zohlelo lokusebenza:
1) Ulwazi oluyisethenjwa:
amanani okubekezelela izilinganiso kusuka ku-1 kuya ku-10,000 mm ahambisana ne-ГОСТ 25346, ISO-286, ГОСТ 25348;
ukubekezelelana nokulingana ngokuhambisana ne-ASME B 4.1 (ANSI B 4.1).
Isiguquli samayunithi wobude ukusuka kumamilimitha ukuya kumayintshi;

2) Ukukhethwa kokubekezelelana kosayizi, ngokuya ngokuphambuka kosayizi onikeziwe (kunikeza izinketho ezi-5 zokubekezelela). Futhi ukukhethwa kokubekezelelana kusebenzela ukubekezelelana ngokusho kwe-ASME B 4.1 (ANSI B 4.1);

3) Ukukhethwa kokulingana kuzosiza, ngokusho kwenani lesayizi elinikeziwe kanye nokuphambuka okukhethiwe kwe-shaft noma umgodi, kuzosiza ukukhetha ukulingana kwengxenye yokukhwelana ngokunqunywa kwegebe nokuqina kokuxhumeka.

4) Isigaba Sokubekezelelana Komumo sibonisa incazelo emfushane yereferensi yengxenye yejiyomethri ngokuhambisana ne-ISO 1101 kanye ne-Russian ГОСТ 2.308.

5) Ukubekezelelana kwe-engeli kubonisa ukuphambuka kwamanani wezilinganiso ze-angular, kuguqula inani le-taper libe i-engeli (ngamayunithi wedesimali namadigri - iminithi - yesibili). Ukubalwa kukanxantathu kunquma zonke izinhlangothi.

6) Ukubala kobukhulu kuyithuluzi elikahle kakhulu lokunquma ngokushesha inani lesixhumanisi sokuvala. Isigaba sixazulula inkinga ephambene ngendlela yobukhulu obuncane. Zonke izibalo zilondoloziwe.

7) Ukubekezelela ukusakaza kufaka phakathi inani lokuchezuka kuye ngesigaba sokunemba esikhethiwe. Amakilasi okunemba avunyelwe anqunywa ubuchwepheshe obukhethiwe bokusakaza, konke kuthuthukiswa ngokuhambisana ngokugcwele ne-russian ГОСТ.

Inqubomgomo yokukhangisa yohlelo lokusebenza - ukukhangisa okukhona akuphazamisi umsebenzisi, azikho ukukhangisa kwe-interstitial.

Noma yimiphi imininingwane ehlinzekwe yisicelo ingeyereferensi kuphela.
