Iibholithi zokwandiswa kweankile yekhonkrithi

Iibholiti zokwandisa ezinomgangatho wokusebenza we-4.6 zibhekisa ku:

1. Amandla e-tensile ye-nominal ye-bolt material yokwandisa ifikelela kwinqanaba le-MPa ye-400;

2. Umlinganiselo wamandla esivuno sezinto zebholithi yokwandisa ngu-0.6;

3. Amandla emveliso yegama lemathiriyeli yebholithi yokwandisa ifikelela kuma-400 × 0.6=240MPa kwinqanaba

4. Ubunzulu bokomba: Kungcono ukuba malunga neemilimitha ezi-5 ubunzulu kunobude bombhobho wokwandisa.

5. Iimfuno zebholithi yokwandisa emhlabeni ngokuqinisekileyo zinzima ngakumbi, nazo zixhomekeke kwimeko yamandla ento ofuna ukuyilungisa. Amandla oxinzelelo afakwe kwikhonkrithi (C13-15) aphindwe kahlanu kunoko kwizitena.

6. Emva kokufaka ngokuchanekileyo i-M6/8/10/12 bolt yokwandisa kwikhonkrithi, ubuninzi bayo obufanelekileyo boxinzelelo lwe-static yi-120/170/320/510 kilograms, ngokulandelanayo.

7. I-screw yokwandisa iqulethwe ngamacandelo afana ne-screw kunye ne-tube yokwandisa. Umsila we-screw u-conical, kwaye ububanzi bangaphakathi be-cone bukhulu kunobubanzi obungaphakathi bombhobho wokwandisa. Xa i-nut iqinisiwe, i-screw ihambela ngaphandle, kwaye ukuhamba kwe-axial yentambo kubangela ukuba inxalenye ye-conical ihambe, ngaloo ndlela yenza uxinzelelo olukhulu olulungileyo kumphezulu wangaphandle we-tube yokwandisa. Ukongezelela, i-angle ye-cone incinci kakhulu, nto leyo eyenza i-friction self-locking phakathi kodonga, ityhubhu yokwandisa, kunye ne-cone, ngaloo ndlela ifezekisa umphumo wokulungisa;

8. I-spring washer kwi-screw yokwandisa inxalenye esemgangathweni ngenxa yokuba ukuvulwa kwayo kuphazamisekile kunye ne-elastic, ngoko kuthiwa yi-spring washer. Umsebenzi we-spring washer kukusebenzisa i-angle ebukhali yokuvuleka okuxubileyo ukugqobhoza kwi-nut kunye ne-flat washer, ukukhusela i-nut ukuba ingakhululeki;

9. I-washer yeflethi nayo iyinxalenye eqhelekileyo, kwaye umsebenzi wayo kukusabalalisa ngokulinganayo uxinzelelo lwe-nut kwiindawo ezidibeneyo.

Ubungakanani bokusetyenziswa kwezikrufu zokwandisa

Izikrufu zokwandisa zineengenelo zokomba okuncinci, amandla okuqina aphezulu, kunye nokuvezwa caba emva kokusetyenziswa. Ukuba azisetyenziswanga, zinokususwa ngokulula ukugcina udonga luthe tyaba. Zisetyenziswa ngokubanzi kwiziganeko ezahlukeneyo zokuhombisa.
