Txoj siv txoj siv sia, uas siv txoj siv tawv hniav, yog ib qho ntawm cov khoom qub tshaj plaws. Txawm li cas los xij, txawm tias qhov tseeb tias txoj kev sib kis no tau tsim los ntev dhau los, nws tseem siv niaj hnub no.

Txoj siv tawv

Nws yuav tsum tau hais tias muaj ntau txoj siv sib txawv uas tuaj yeem siv rau hauv txoj siv sia. Nyob ntawm lawv ntu, cov hlua khi tau muab faib ua:

• flat;
• wedge;
• poly-wedge;
• ncig;
• toothed.

Nws tseem tuaj yeem ntxiv tau tias muaj ntau phau ntawv qhia thiab lwm qhov chaw uas piav qhia txog V-siv los yog txoj siv tawv tiaj tus kom meej. Tab sis nrog cov hniav txhuam hniav, txhua yam yog me ntsis zuj zus, txij li cov cuab yeej tshwj xeeb no tau siv tsis ntev dhau los. Txawm hais tias rov qab mus rau lub sijhawm ntawm USSR, OST 38 - 05114 - 76 thiab OST 38 - 05227 - 81 tau tsim. Kev suav rau cov siv txhuam hniav thiab cov hniav txhuam hniav.

Txoj kev siv txoj siv sia

Nws davNws yog hom siv no uas tau nthuav dav vim tias nws muaj qee yam zoo. Cov txiaj ntsig no suav nrog:

• Lub peev xwm ntawm cov hlua no siab.
• Cov khoom muaj qhov me me.
• Ntxhis ntawm cov hlua no tsis muaj kiag li vim lawv tsim.
• Cov siv tawv no tso cai rau cov iav siab sib piv.
• Tus yam ntxwv ceev ntawm lub sijhawm siv kuj tseem siab heev - txog 50 m / s.
• Vim qhov me me ntawm txoj siv tawv nruj, qhov cuam tshuam ntawm lub ncej thiab qag me me.
• Qhia me ntsis suab nrov.
• ua haujlwm siab heev - txog 98%.

Nws tseem ceeb heev kom nkag siab tias kev tsim cov hlua khi yog ua tiav nrog qee yam kev cai uas nws yuav tsum tau ua. Cov kev cai no suav nrog:

• roj tsis kam;
• siv qhov ntsuas kub ntau (nws yuav tsum nyob nruab nrab ntawm -20 txog +100 ° C);
• ozone resistance;
• tsis rhiab rau huab cua.

Shape of straps

Tam sim no, cov hniav txhuam hniav tuaj yeem muab faib ua ob peb pawg nyob ntawm cov hniav uas nws muaj. Muaj cov hniav nrog cov duab semicircular lossis nrog cov duab trapezoid.

Qhov kom zoo dua ntawm cov hniav ib nrab yog tias lawv muab kev faib tawm ntau dua ntawm kev ntxhov siab hauv txoj siv, ua kom cov kev txwv ntawm cov khoom tuaj yeem ua tau.hloov los ntawm 40%, nrog rau smoother meshing ntawm cov hniav. Yog hais tias peb tham txog xws li siv nyob rau hauv dav dav, ces tus nqi ntawm ib txwm thiab ib nrab voj voog cov hniav yog tib yam, tab sis cov kev ua tau zoo ntawm ob hom yog kom meej meej dua.

Cov khoom siv no muaj ntau yam:

1. Ntseeg cov hniav, nrog rau txheej saum toj kawg nkaus ntawm txoj siv.
2. Cov cab kuj sib txuas.
3. Cov txheej txheem qis ntawm txoj siv ua los ntawm polyamide ntaub.

Kev npaj

Tam sim no, siv sijhawm ntev tau nthuav dav hauv kev lag luam engineering. Cov khoom no suav hais tias yog qhov ruaj khov, tab sis tib lub sijhawm nws muaj qhov tsim nyog elasticity.

Cov khoom no muaj peb txheej. Thawj txheej yog cov txheej txheem load-bearing thiab tseem txiav txim siab qhov siab tshaj plaws uas txoj siv sia tuaj yeem tiv taus thiab nws lub zog. Kev tsim cov txheej txheem no yog ua los ntawm cov hlua, uas yog ua los ntawm fiberglass lossis Kevlar.

txheej thib ob ntawm lub sijhawm siv sijhawm yog ua los ntawm polyurethane lossis roj hmab. Nws yuav tsum muab qhov tsim nyog hloov tau thiab elasticity ntawm tag nrho txoj siv. Qhov kawg, thib peb txheej, yog ua los ntawm nylon lossis lwm yam khoom siv hluavtaws. Txhawm rau muab tag nrho peb txheej rau hauv ib qho thiab tsim ib txoj siv tsav, siv cov txheej txheem vulcanization.

Qhov zoo ntawm cov khoom tsav

Qhov zoo tshaj plaws thiab tseem ceeb tshaj plaws ntawm hom kev siv no yog nws qhov siab tshaj plawscoefficient ntawm kev ua tau zoo, uas yog, efficiency. Feem ntau, siv cov hlua khi, txawm tias lawv yog ua los ntawm polyurethane lossis roj hmab, yog siv los ua kom nrawm dua.

Cov khoom zoo li no ua tau zoo heev rau lub laub, noj cov duab tsim nyog, uas muab tag nrho cov ntsuas tsim nyog. Lwm qhov ntawm cov tsis tsim nyog tseem ceeb yog qhov yooj yim heev ntawm txoj siv. Txhawm rau txo qhov kev pheej hmoo ntawm kev tawg txoj siv hauv cov chaw uas muaj qhov hluav taws xob siab tshaj plaws, nws tau muab cov hniav tshwj xeeb zoo li tus.

Lwm qhov tseeb uas yuav tsum tau saib xyuas yog qhov kev ncua deb ntawm cov ncej thaum siv lub zog siv. Thaum lub sij hawm siv cov ntaub ntawv tsav tsheb, ib qho me me ntawm qhov nruab nrab ntawm cov shafts tau tso cai, uas ua rau muaj kev nce hauv qhov nrawm ntawm nws cov ntsiab lus, thiab tseem ua rau muaj kev nce hauv lub zog uas txoj siv sia muaj peev xwm kis tau tus mob. Nws tseem tsim nyog sau cia tias lawv siv tau zoo txo qhov kev vibration ntawm cov ntsiab lus txawm tias thaum muaj cov khoom sib cuam tshuam tau ua tiav, thiab kev swb tsis pom nyob rau hauv nws tus kheej.

PU pluaj

Kev siv lub sijhawm siv polyurethane qhib tau ntau dua rau lawv siv. Vim muaj ntau yam kev xaiv tsim thiab siv ntau rau cov khoom siv zoo li no, lawv tuaj yeem siv rau ntau yam kev lag luam.

Vim lawv cov khoom, polyurethane sij hawm siv tau pom lawvdaim ntawv thov ntawm linear thiab thauj khoom. Tsis tas li ntawd, lawv tuaj yeem siv tau rau hauv ntau lub tshuab nqa lossis txawm tias hauv kev ntxhua khaub ncaws. Kev siv cov hniav txhuam hniav ntawm hom no yog ua tau thaum txhim kho cov rooj vag lossis lub qhov rooj uas qhib tau, lawv tuaj yeem siv tau rau hauv cov neeg hlau. Nws tuaj yeem ntxiv tau tias txoj siv polyurethane tuaj yeem ua tau ob qho tib si thiab ob sab. Tsis tas li ntawd, lawv yuav muaj cov txheej txheem uas tsis yog txheej txheem lossis ib qho txawv txav ntawm cov hniav.

Toothed txoj siv sia sib txawv ntawm cov hniav. Cov hom hauv qab no yog qhov txawv:

• trapezoidal profile;
• semicircular profile;
• toothed ob sab.

Toothed belt repair

Koj tuaj yeem xav txog cov txheej txheem ntawm kev hloov txoj siv txhuam hniav uas siv cov piv txwv ntawm lub cav tsib lub tog raj kheej. Nws yog ib qho tsim nyog pib nrog qhov tseeb tias txhawm rau ua qhov haujlwm no ntawm lub cav no, koj yuav tsum muaj cov cuab yeej tshwj xeeb los ntawm V. A. G.

Yuav kom tshem tawm qhov xav tau, nws yog qhov yuav tsum tau loosen cov vibration damper fasteners. Nws yog mounted rau pem hauv ntej ntawm lub crankshaft. Tom qab tshem tawm txoj siv, koj yuav tsum tau rov nruj dua lawv siv lub nozzle tshwj xeeb, uas yog tsim los rau lub torque ciaj ntswj. Yog hais tias lub cav yog plaub-lub tog raj kheej, ces cov txheej txheem hloov yog raws li nram no:

1. Lub piston tau teeb tsa hauv thawj lub tog raj kheej hauv V. M. T.
2. Belt cover tshem tawm.
3. Txoj pluaj yog loosened thiab tshem tawm.
4. Ib txoj siv tshiab tab tom raug teeb tsa.

Nws tsim nyog sau cia tias yog tias lub tog raj kheej lub taub hau raug tshem tawm thaum hloov txoj siv, ces cov roj faib theem yuav tsum tautswj.
