Paub txhua yam txog cov txiv ntseej slotted yog qhov tsim nyog tsis yog rau cov xauv xauv, cov neeg teeb tsa thiab lwm tus kws tshaj lij, tab sis kuj rau cov neeg zoo tib yam. Cov khoom lag luam zoo li no yuav tsum ua raws li GOST 11871-88. Thiab koj tseem yuav tsum tau ua nrog lub qhov (socket) taub hau ntawm cov txiv ntseej slotted, nrog puag ncig, ntsuas phoo thiab ntsuas qhov tseeb, nrog cov yam ntxwv ntawm lawv cov cim thiab zawm. Hauv kab lus no, peb yuav tshuaj xyuas txhua yam hais txog txiv ntseej slotted.

Peculiarities

Cov txiv ntseej slotted yog muab los ntawm ntau lub tuam txhab thiab tam sim no muaj nyob hauv thaj tsam ntawm txhua lub tuam txhab ua lag luam. Kev siv tshuab, nws yog "tsuas yog" lub nplhaib hlau. Ib txoj xov yog siv rau lub qhov ntawm cov khoom los ntawm sab hauv. Hauv qhov no, qhov tshwj xeeb tau siv rau sab nraud, uas tau muab lub npe rau cov khawm nrawm. Cov grooves no tau tsim los siv milling.

Lub luag haujlwm ntawm qhov nqes yog txhawm rau txhawm rau txhawm rau kho qhov khoos phis tawj ncig nws cov axis. Tus lej ntawm qhov qhib yuav tsum sib haum rau ntu ntawm cov khoom. Slotted kho vajtse tsis tshua siv rau cov xov sib txuas ua ke, tab sis lawv xav tau zoo hauv ntau yam lag luam, uas yog:

• tshuab cuab yeej lub tsev;
• kev lag luam tsheb;
• lwm ceg ntawm kev siv tshuab engineering.

Cov no yog cov chav nyob feem ntau uas muaj cov ncej thiab lwm qhov sib sib zog nqus. Kev thauj khoom ntawm lub qhov khawm nrawm yog siab heev, yog li nws yuav tsum muaj kev ntseeg siab thiab ruaj khov. Rau nws cov khoom siv, tsuas yog hlau nrog lub zog tsawg kawg 36 HRS tau siv . Qhov tob tob tshaj plaws yog 0.1 cm.

Qee hom txiv ntseej tau siv nyob rau hauv ib puag ncig txhoj puab heev, yog li ntawd lawv tau npog tshwj xeeb npog.

Yuav tsum muaj

Cov ntsiab lus tseem ceeb tau teev tseg hauv GOST 11871-88. Nws siv rau puag ncig qhov sib npaug ntawm qhov tseeb qib A. Cov ntsiab lus hauv qab no tau ua kom zoo:

• nominal xov seem;
• cov kauj ruam ntawm kev thov cov xov no;
• tus naj npawb ntawm qhov qhib;
• theoretical hnyav ntawm tus qauv.

Kev tshuaj xyuas cov txiv ntoo tuaj yeem ua tiav qhov muag pom. Hauv qhov no, cov cuab yeej siv tsis tau siv, tab sis yuav tsum muaj lub teeb pom kev hauv chav tsawg kawg 300 lux. Hauv cov xwm txheej nyuaj, cov loops zoo ib yam nrog qhov nce ntawm 2, 3-5 tau siv. Hauv qhov kev piav qhia ntawm kev tswj hwm tus txheej txheem hauv 11871-88, cov ntaub ntawv hais txog tau ua rau lwm yam kev coj ua uas piav qhia hauv qab no:

• kawm txog kev zam thiab sib txawv ntawm lawv;
• txiav txim siab ntawm qhov nyuaj ntawm cov cua sov kho cua sov;
• qhov kev txiav txim ntawm kev sib piv nrog cov qauv ntxhib;
• cov cai rau kev tshuaj xyuas qhov tsis xws luag thiab thov txheej txheej;
• qib ntawm kev tso cai qag load.

Nws kuj tseem muaj txiaj ntsig los mloog zoo rau GOST 11871-80 . Nws npog puag ncig cov noob txiv ntoo nrog ntu xov ntawm 0, 4–20 cm. Cov pawg qhov tseeb yuav tsum yog A lossis B. Thaum kawg, nws yog qhov tsim nyog los ua tib zoo saib ntawm 8530-90 tus qauv, uas txhais cov yam ntxwv ntawm cov txiv ntseej, tshuab ntxhua khaub ncaws. thiab cov zauv rau kho thiab tshem tes tsho. Qhov loj ntawm lub taub hau yuav tsum yog sib npaug rau txoj kab uas hla ntawm ntu tseem ceeb.

Ua tsaug rau qhov tshwj xeeb grooves, nws yog qhov yooj yim thiab nrawm rau nruab cov txiv ntoo hauv qhov chaw. Kev rhuav tshem nws hloov tawm mus yuav tsis nyuaj dua. Dab tsi yog qhov tseem ceeb, txheej txheem teeb tsa tshwm sim sai txawm tias nyob hauv qhov xwm txheej nyuaj. Xauv qhov hloov pauv cov noob txiv ntoo yog qhov tsim nyog siv ntau lub tshuab ntxhua khaub ncaws. Cov tshuab ntxhua khaub ncaws no tau nruab nrog "ob txhais ceg" sab nraud, thiab ib qho protrusion nyob hauv. Rau cov tshuab ntxhua khaub ncaws, yuav tsum tau ua raws li tus txheej txheem 11872. Lawv kuj muaj qhov ntev me me radial.

Muaj peb yam tseem ceeb ntawm hom spline fasteners:

• tsis muaj chamfer txhua;
• nrog ib qho yooj yim chamfer;
• nrog tus chamfer, tab sis tib lub sijhawm nrog puag ncig.

Hlau qib 14X17H2, 12X18H10T, 12X18H10T tuaj yeem siv ua raw khoom. Cov ntaub ntawv zoo li no tau coj los txhim kho kev txhim kho corrosion. Raws li qhov xwm txheej, "yooj yim" cov hlau carbon ntawm pawg 20, 35 thiab 45 yog qhov nyiam dua. Ntawm tooj dag, tsuas yog qib L63 yog qhov tsim nyog.

Hlau qib 35 tsuas yog siv rau kho vajtse nrog xov tsawg kawg 0, 6 thiab tsis ntau dua 4, 8 cm . Nws yuav tsum tau nqa lub nra los ntawm 13.2 txog 240.7 kN. Nov yog qhov xav tau rau kev tswj hwm lub Hoobkas kaw hauv tus qauv. Yog li ntawd, nws yog ib qho tseem ceeb kom xav tau kev nthuav qhia cov ntawv pov thawj nrog cov cim tsim nyog.

Cov khoom siv kho vajtse nrov kho nrog roj phosphate, zinc, ua ke ntawm cadmium thiab chromium.

Npav

Qhov ntev ntawm nominal txoj kab uas hla tuaj yeem yog:

• 6;
• 8;
• 10;
• 12;
• 14;
• 16;
• 18;
• 56;
• 80;
• 95;
• 170;
• 200 hli (tseem muaj lwm qhov ntev).

Kev ntim khoom ntim yuav tsum muaj cov hauv qab no:

• cov cim lag luam (qee zaum ua ke nrog lub npe ntawm lub tuam txhab);
• cov paib qhia txog kev kho vajtse;
• nqa qhov hnyav lossis ntau ntau hauv daim.

Tsuas yog cov fasteners ntawm hom sib xws kiag li tuaj yeem tso rau hauv txhua pob. Ntawd yog, yog tias cov qauv puag ncig tau muab tso rau ntawd, tom qab ntawd plaub fab thiab lwm yam duab tsis tuaj yeem siv tau. Tib yam siv rau qhov ntev, cov khoom siv thiab txheej txheej siv. Rau kev tsim cov txiv ntoo slotted, tuaj yeem siv cov hlau tsis xeb lossis tooj dag. Ntau txheej txheej tuaj yeem thov hla cov hlau tsis huv.

Xauv lub tshuab ntxhua khaub ncaws tuaj yeem los ntawm HM 3044 txog HM 3192 . Lwm qhov ua tau yog los ntawm HM 30/500 txog HM 30/710. Qhov hnyav ntawm cov txiv ntoo hauv qhov cim tau suav los ntawm kev xav ntawm qhov ntom ntawm cov hlau 7, 85 g rau 1 sq. pom Qee zaum nws tau siv los thov tsis yog trapezoidal, tab sis cov xov ntsuas - uas yuav tsum tau cim.

Kev kos npav yog siv rau qhov kawg ntawm qhov khoom.

Yuav ua li cas ntswj lawv?

Daim ntawv thov yog kab tias qhov tseem ceeb tshaj plaws thaum nws los txog rau txiv ntseej. Los ntawm lub neej ntawd, lawv tau siv los kho qhov chaw coaxial nruj . Nws yog ib qho kev coj ua siv lub vojvoog (tseem hu ua collet) cov yuam sij. Lawv tau tuav hauv daim ntawv ntawm ib qho arc, xaus rau hauv qhov trailer uas zoo li tus nqaj hauv qhov tsos. Tau kawg, yuav tsis muaj lus nug txog kev siv tus ntsia hlau.

Lub xeev tus txheej txheem tau kho 21 hom ntawv tseem ceeb rau txhua tus txiv ntoo . Cov yuam sij no yog tsim los ntawm cov hlau nrog ntxiv ntawm chromium. Qee zaum cov cuab yeej tig tau siv. Nws txaus kom muaj ib tus yuam sij rau txhua pab pawg me me thiab siv nws raws li xav tau. Hauv qee kis, lub qhov (socket) lub taub hau pab ua haujlwm nrog cov txiv ntseej.

Lawv ua haujlwm txawm tias muaj qhov chaw me me rau khawm nrawm thiab tib lub sijhawm txo qhov kev hloov pauv tag nrho ntawm cov khoom.
