Zomwe zimagwiritsidwa ntchito nthawi zambiri za zomangira

1. Zomangira zomwe zimagwiritsidwa ntchito nthawi zambiri zimaphatikizapo:nangula wedge (ETA WEDGE ANCHOR), ndodo za ulusi, hex bawuti, hex nati, wochapira flat, bulaketi ya photovoltaic

2. Kulemba zilembo zomangira

M6 imatanthawuza kukula kwake kwa ulusi (m'mimba mwake waukulu wa ulusi)

14 amatanthauza kutalika kwa ulusi wamwamuna L wa ulusi

Monga: hex mutu bawuti M10 * 1.25 * 110

1.25 akunena za phula la ulusi, ndipo ulusi wabwino uzikhala ndi chizindikiro. Ngati yasiyidwa, ikuwonetsa ulusi wokakala..

3. Magwiridwe mlingo wa fasteners

Maphunziro a bolt amagawidwa m'makalasi opitilira 10 monga 3.6, 4.6, 4.8, 5.6, 6.8, 8.8, 9.8, 10,9, 12.9, etc., omwe ma bawuti a giredi 8.8 ndi pamwambapa amapangidwa ndi chitsulo chochepa cha carbon alloy kapena sing'anga mpweya zitsulo ndipo akhala kutentha ankachitira (kuzimitsa, tempering, etc.) moto), amene amadziwika kuti mkulu-mphamvu mabawuti, ndi ena onse amatchedwa mabawuti wamba. Cholembera cha kalasi ya bawuti chimakhala ndi magawo awiri a manambala, omwe motsatana amayimira kuchuluka kwamphamvu kwamphamvu komanso kuchuluka kwamphamvu kwazinthu za bawuti. Nambala isanakwane decimal imayimira 1/100 ya kuchulukirachulukira kwa zinthu, ndipo nambala pambuyo pa decimal imayimira nthawi 10 chiŵerengero cha malire a zokolola mpaka malire amphamvu azinthu.

Mwachitsanzo: magwiridwe antchito 10.9 mabawuti amphamvu kwambiri, tanthauzo lake ndi:

1. Mphamvu yodziwika bwino ya bawuti imafika 1000MPa;

2. Chiŵerengero cha zokolola za bawuti ndi 0,9;

3. Mphamvu zokolola mwadzina za bolt zimafika 1000 × 0.9 = 900MPa;

Tanthauzo la kalasi ya bolt ndi muyezo wapadziko lonse lapansi. Maboti a kalasi yofananira yogwira ntchito amakhala ndi ntchito yofanana mosasamala kanthu za kusiyana kwa zida zawo ndi zoyambira. Gawo la magwiridwe antchito okha ndi omwe angasankhidwe kuti apangidwe.

Mlingo wa mtedza umagawidwa m'makalasi 7, kuyambira 4 mpaka 12, ndipo chiwerengerocho chimasonyeza 1/100 ya kupsinjika kochepa komwe mtedza ungathe kupirira.

Magulu ochita bwino a mabawuti ndi mtedza ayenera kugwiritsidwa ntchito molumikizana, monga ma bolt a giredi 8.8 ndi mtedza wa giredi 8.
