Mitundu ya ulusi ntchito makina

Kusema ndi florid helix ndi phula zonse oyenerera pa conical kapena cylindrical pamwamba. Ndi chinthu chachikulu polumikiza mitundu iwiri fasteners, komanso wononga ndi imodzi helical zida. magawo Basic ulusi pa makono Fasteners akufotokozera GOST 11708-82: izi phula ulusi pakati convolutions pafupi, lakunja ndi mumtima diameters wa amafotokozera fastener, vertex ngodya ya ulusi.

Mitundu ya ulusi pa fasteners ndi anawagawa:

• zoweta - chagwiritsidwa nati, malaya anangula couplings, chitoliro;
• kunja - anayikidwa pa zomangira, zomangira, zomangira, akapichi, studs.

Zotsatirazi mitundu ya ulusi pa alendo lolingana:

• Chinkafunika - mbiri mu mawonekedwe a chinthu cha makona equilateral (nthawi zina zazing'ono, sing'anga ndi njira yaikulu);
• inchi - triangular kapena trapezoidal mawonekedwe;
• Chinkafunika conical - ali ndi mbiri triangular;
• wozungulira - vertex ziyerekezo mawonekedwe zozungulira;
• trapezoidal - pamwamba trapezoidal protrusion;
• Zosagwira - asymmetrical trapezoidal mbiri;
• Yodziyimira payokha - trapezoidal mbiri;
• conical chubu ndi cylindrical (ali mawonekedwe a chinthu cha makona isosceles ndi anamaliza inchi kukula (kapena ploskosrezannoy) nsonga ndi ufa koyilo);
• conical inchi - ploskosrezannoy mbiri ndi pamwamba wa mawonekedwe triangular.

Palinso mitundu ina ya ulusi, ngati lalikulu ndi anayi. Iwo chagwiritsidwa lathes fasteners kwa zojambula payekha. Izi mitundu ya ulusi Musapereke digiri yapamwamba molondola, kotero kawirikawiri ntchito. Iwo kulibe alendo.

Pakali pano, chifukwa ntchito zomangamanga zofunika akunja mkati ulusi chinkafunika imatengedwa. Mu zojambula, izo amaimira likulu kalata "M" kusonyeza m'mimba mwake kunja mu millimeters. Mitundu chitoliro ulusi ntchito kulumikiza mipope osiyana. awiri awo mwadzina ndi mkati mwake wa chitoliro, ndi kunja kwa amene ali yamazinga. Mu zojambula, izo amaimira likulu kalata «G» umboni ndi awiri lamkati la chitoliro mu mainchesi.

Waukulu ulusi makulidwe a mitundu yonse ndi deta pakuyenerera. Angapezeke mu makaniko chilichonse cha bukhu. deta lina ulusi chinkafunika anafotokoza malinga GOST 9150-81, 8724-81, ndi 24705-81. Chitoliro zamitundu cylindrical ulusi ndi kutchulidwa GOST 6357-81.

Mmodzi wa fasteners ofanana ndi ulusi chinkafunika ndi bauti. Ndi zitsulo ndodo ndi mutu kumapeto wina. Pamodzi kutalika kwa ndodo ntchito kwa poyambira helical. Cholinga akapichi - kugwirizana kwa mbali zosiyanasiyana za njira ziwembu mwa mtedza. Wathandizidwa mutu ndi hexagon mphako, ndipo (chinsinsi, theka chonse, mbuyo, BS, osachiritsika).

Mitundu zotsatirazi akapichi ngati anafuna:

• Mipando - ntchito kulumikiza katundu mu kupanga mipando;
• zomangamanga - ntchito mu gawo malonda;
• pulawo - anaikira kuchita makina mu gawo la ulimi;
• magalimoto - ntchito amakulitsa zitsulo zosiyanasiyana ndi guardrails.
