Tsanangudzo yefastener thread
Rwonzi chiumbwa chine yunifomu spiral protrusion pamusoro pekunze kana mukati pechinhu chakasimba.
Kune marudzi matatu makuru eshinda: shinda, tambo yekuzvirova wega uye yekuzvirovera wega.
Machine thread:panguva yegungano, chera gomba mugungano kuti ubate shinda, uye tambo yemukati yakadhindwa yakafanana neshinda yekunze ye screw, saka gungano rinoitwa nediki torque.
Kuzvirova wega:panguva yegungano, chera maburi mugungano kutanga, pasina kurova mazino emukati, uye shandisa torque yakakura yekuungana.
Self-drilling thread:inogona kushandiswa zvakananga pagungano, uye screw inogona kudhirwa uye kubatwa kuti iite shinda mune imwe nhanho.
Screw chiito chefastener
1. Kutsanya uye kubatanidza basa: inoshanda kune akawanda screw zvigadzirwa panguva ino.
2. Transmission action (displacement action): somuenzaniso, micrometer inoshandiswa neQC kutarisa zviyero.
3. Basa rekuisa chisimbiso: sekubatanidza uye kuiswa chisimbiso kwepombi.
Shinda yakakora neshinda yakanaka
Iyo inonzi coarse thread inogona kutsanangurwa seyakajairika shinda; Zvisinei, shinda yakatsetseka inoenderana neshinda yakakoshwa. Pasi pedhayamita imwechete yezita, nhamba yemazino pa inch yakasiyana, kureva kuti, pitch yeshinda yakakora yakakura, nepo iyo yeshinda yakatsetseka idiki. Izvi zvinoreva kuti, kune 1/2-13 uye 1/2-20 tsanangudzo, yekutanga mazino akaoma uye ekupedzisira mazino akanaka. Naizvozvo, inoratidzwa se 1/2-13UNC uye 1/2-20UNF.
Shinda yakakora
Tsanangudzo: Aya anonzi mazino akakora anoreva shinda dzakajaira. Kunze kwekunge zvatsanangurwa neimwe nzira, zvibatiso zvakaita semasikiru esimbi esimbi ayo atinowanzo tenga mazino akagosha.
Hunhu hweshinda yakaoma: ine simba rakawanda, kuchinjika kwakanaka uye inogona kufananidzwa nezviyero. Kazhinji kutaura, shinda yakaoma inofanira kunge iri sarudzo yakanaka;
Kuenzaniswa neshinda yakanaka: nekuda kweiyo gombe, yakakwira tambo angle uye kusazvivharira, zvinodikanwa kuisa cheki washer uye yekuzvivharira mudziyo munzvimbo yevibration; Iine zvakanakira nyore disassembly uye gungano, yakakwana inofananidzwa chiyero zvikamu uye nyore kuchinjana;
Ongorora: Hazvifanirwe kutara kukwirira kweshinda yakaoma, yakadai seM8, M12-6H, M16-7H, nezvimwewo, uye inonyanya kushandiswa seshinda yekubatanidza.
Fine thread
Tsanangudzo: Mazino akanaka anongopesana nemazino akakasharara, ayo anotemerwa kuwedzera izvo zvakakosha zvekushandisa izvo shinda dzemeno akagosha dzisingakwanise kusangana. Shinda dzemazino akanaka zvakare dzine nhevedzano yepikisi, uye kukwirira kwemazino akanaka idiki, saka hunhu hwayo hunoita kuti uzvivhare wega uye unopesana nekusunungura, uye huwandu hwemazino hunogona kuderedza kubuda uye kuzadzisa chisimbiso. Mune dzimwe nguva dzakanyatsojeka, mazino-akanaka-stainless simbi screws ari nyore kudzora chaiko uye kugadzirisa.
Zvakaipa: Kukosha kwekusimba uye simba zvakaderera pane zvemazino akakasharara, uye shinda iri nyore kukuvara. Hazvikurudzirwi kuparadzanisa uye kuungana kakawanda. Zvisungo zvinofananidzwa senge nzungu zvinogona kunge zvakaenzana, uye saizi yacho haina kunaka zvishoma, izvo zvinogona kukuvadza zviri nyore masiruru nenzungu panguva imwe chete.
Kushandisa: Fine thread inonyanya kushandiswa mu metric pipe fittings ye hydraulic system, mechanical transmission parts, thin-walled parts ine simba risina kukwana, zvemukati zvikamu zvakaganhurirwa nenzvimbo uye shafts ine high self-locking zvinodiwa, etc. Kana shinda yakanaka yamaka, iyo pitch inofanira kuiswa chiratidzo kuratidza mutsauko kubva kune yakakosha shinda.
Nzira yekusarudza sei coarse thread uye yakanaka thread?
Zvese zviri zviviri shinda yakakasharara nemafine shinda screws anoshandiswa pakusunga.
Fine-tooth screws anowanzo shandiswa kukiya zvitete-madziro zvidimbu uye zvikamu zvine zvakakwirira zvinodiwa pakudzivirira kuzunguzika. Fine thread ine yakanaka yekuzvivharira kuita, saka ine yakasimba anti-vibration uye anti-kusunungura kugona. Nekudaro, nekuda kwekudzika kudzika kweshinda, kugona kutakura tension yakakura kwakaipisisa kupfuura kweshinda yakakasharara.
Kana pasina matanho ekudzivirira-kusunungura anotorwa, anti-kusunungura mhedzisiro yeshinda yakatsetseka iri nani pane iyo yeshinda yakakasharara, uye inowanzo shandiswa kune dzakatetepa-madziro zvidimbu uye zvikamu zvine yakakwirira anti-vibration zvinodiwa.
Pakugadzirisa, shinda yakanaka ine zvimwe zvakanakira. Kuipa kweshinda yakanaka: Haina kukodzera zvinhu zvine chimiro chakanyanya chakakora uye isina simba. Kana simba rekusimbisa rakanyanya kukura, zviri nyore kutsvedza.
