Ibholithi yesakhiwo sentsimbi
Ingcaciso yeMveliso
>>>
Ibholithi yesakhiwo sensimbi luhlobo lwebholithi ephezulu kunye nohlobo lwenxalenye esemgangathweni. Iibholiti zesakhiwo sensimbi zisetyenziswa kakhulu kubunjineli besakhiwo sensimbi ukudibanisa iindawo zokudibanisa iiplati zesakhiwo sensimbi. Iibholiti zesakhiwo sentsimbi zahlulwe zaba ziibholiti ezityebileyo ezinokuqina okuphezulu kunye neebholiti ezinkulu ezine-hexagonal zokuqina. Iibholiti ezinkulu ezinobuxhakaxhaka obuphezulu obunehexagonal zezenqanaba eliphezulu le-screws eziqhelekileyo, ngelixa iibholithi eziguquguqukayo zohlobo lokucheba ezomeleleyo ziluphuculo lweebholithi ezinkulu ezine-hexagonal zokuqina okuphezulu. Ukwakhiwa okungcono, ukwakhiwa kweebholithi zensimbi kufuneka ziqiniswe kuqala kwaye ekugqibeleni. Ukuqiniswa kokuqala kweebholiti zesakhiwo sentsimbi, uhlobo lwempembelelo yombane okanye i-torque adjustable wrenches yombane iyafuneka. Ukuqiniswa kokugqibela kweebholiti zesakhiwo sensimbi kuneemfuno eziqinileyo. Ukuqiniswa kokugqibela kohlobo lweebholithi zentsimbi yohlobo lokucheba kufuneka kusetyenziswe isikrufu sombane sohlobo lokucheba, kwaye ukuqiniswa kokugqibela kohlobo lwe-torque yeebholithi zesakhiwo sentsimbi kufuneka kusetyenziswe uhlobo lwe-torque yokutshixa sombane. Ibholithi yolwakhiwo lwentsimbi yohlobo lwe-torsional shear ibandakanya ibholithi, i-nati, uhlobo lwe-shear yokucheba eyomelele kakhulu kwisakhiwo sentsimbi enkulu ene-hexagonal kunye newasha.
