Umgangatho wokuhlolwa kweebholithi zamatayara

Umgangatho wokuhlolwa kweebholithi zamatayara ngulo: iibholithi zamatayara ziphelele kwaye azikhululekanga.

I-bolt luhlobo lwe-fastener olubandakanya intloko kunye ne-screw (i-cylinder enemicu yangaphandle), ekufuneka ihambelane ne-nut ukuze ibophe kwaye idibanise iindawo ezimbini ngemingxuma.Amalungu omatshini, izibophelelo ze-cylindrical threaded kunye namantongomane.Ukwahlula kwiibholiti eziqhelekileyo kunye ne-high-high-power bolts, kunye ne-high-high-power bolts ziyi-bolts zamandla aphezulu, eziyingxenye eqhelekileyo.Isici esibaluleke kakhulu seebholiti eziphezulu kukuba zikhawulelwe ekusebenziseni ixesha elilodwa, ngokuqhelekileyo zisetyenziselwa ukudibanisa, kwaye ukusetyenziswa ngokuphindaphindiweyo kunqatshelwe ngokungqongqo.Ngokwemeko yoxinzelelo, ihlulwe ibe: uhlobo lwengxabano kunye noxinzelelo loxinzelelo;ngokwetekhnoloji yokwakha, yahlulahlulwe ibe yi: torsional shear type-high-power bolts kunye neebholiti ezinkulu ezinehexagonal.

Izinto zokuhlola ibholithi:
Ukubhaqwa kwetorque, ukubhaqwa kwetorque, ukubhaqwa kokuqina, ukubonwa kwe-anti-slip coefficient, itorque esebenzayo, ukusebenza kokutshixa, i-torque coefficient, i-axial force yokuqina, i-friction coefficient, anti-slip coefficient, test-screw-in, ukuqina kwegasket, ukuqina, uvavanyo lwe-hydrogen embrittlement, ukuthambisa, ukuvutha, uvavanyo lokuphinda umngxuma, ukugoba, (icala elinye, icala eliphindwe kabini) uvavanyo lokucheba, impembelelo ye-pendulum, ukuphumla koxinzelelo, ubushushu obuphezulu, uvavanyo lonyamezelo loxinzelelo, ukungcangcazela kwecala, uvavanyo lokudinwa, uhlalutyo lwe-metallographic (uhlalutyo lwe-microstructure, uvavanyo lwe-microhardness ), uvavanyo lokwakheka kweekhemikhali, njl.
