1. Tig Tawm Tsov Rog: Torsional force ntawm ib yam khoom yog ua kom pom tau tias nws muaj peev xwm tawm tsam thaum twv ib nrab. Ntau cov qauv tau teev kom muaj qhov tsawg tshaj plaws rau kev tswj tus kheej tapping ntsia hlau torque. Hauv qhov kev sim no, lub kav lub npoo clamped ntawm lub nrig torsion nrog lub tapped splitter nyob nruab nrab ntawm lub kais, thiab tom qab ntawd ces lub qhov ntswj ntawm lub nplaum yuav siv mus txog rau lub dowels tawg. Yog tias lub tshuab tsis muaj zog tshaj qhov tsawg tshaj plaws, qhov kev kuaj ntawd tsis tiav. Unqualified qhia tau hais tias txoj hauv kev uas tus ntsia thawv yog mos los yog xau tau me me.
2. Kev ntsuas xauv: Qhov kev kuaj no yog xauv cov rau tes rau lub rooj tsav tsheb nrog cov lus qhia tawv, tuab thiab lub qhov taub. Yog hais tias tus ntsia thawv yog xauv los ntawm kev kuaj phaj tab sis tus ridges yog deformed, cov khoom yuav tsis. Unqualified qhia tau hais tias qhov tawv tawv tawv ntawm tus ntsia thawv yog qhov muag heev los yog muag heev.
3. Kev Xeem Torsion Test: Qhov kev xeem no tsuas yog tsim nyog rau cov ntsia hlau uas tau raug screwed. Thaum qhov kev ntsuas xauv raug ua tiav, qhov tsawg kawg nkaus locking torque ntawm lub rooj tsav tsheb tau pom. Yog hais tias lub teeb ntswj tshaj qhov ntsuas tshaj tus nqi (qhov nqi tus nqi raws li qhov loj ntawm tus ntsia thawv \ kev kho mob), cov khoom no tsis tsim nyog. Ua tsis tau los qhia tau hais tias qhov saum npoo ntawm qhov ntsia hlau yog tsis tsim nyog lubricated, los yog hais tias lub tav yog tsis zoo tsim thiab yuav tsum tau ntau ntxiv torque.
