Soviet instruments yog ib lub ntsiab lus tshwj xeeb uas koj tuaj yeem tham txog ntau teev. Rau qee tus, lawv yog lub cim ntawm kev tsis yooj yim thiab tsis muaj ergonomics, tab sis ntau tus yuav nco ntsoov lawv qhov zoo thiab kav ntev. Nco txog keeb kwm ntawm kev txiav ntoo hauv peb lub tebchaws, ib tus tsis tuaj yeem tsis quav ntsej Druzhba chainsaw.
Lawv cov khoom loj tau tsim nyob rau xyoo 1955. Nws yuav tsum tau muab sau tseg tias twb peb xyoos tom qab, "Druzhba" tau txais ib tug kub puav pheej ntawm lub exhibition ntawm kev nrhav, uas tau muaj nyob rau hauv Brussels. Los ntawm txoj kev, lub saw tau txais nws lub npe nco vim yog kev ua koob tsheej ntawm hnub tseem ceeb ntawm Ukraine nkag mus rau Russia.
Pib txij xyoo 1990, txawm tias cov tuam txhab ntiag tug tau pib tsim cov khoom seem rau cov saws no. Txawm hais tias muaj ntau xyoo dhau los txij li qhov kev tso tawm ntawm tus qauv qub dhau los, Druzhba chainsaws tseem nyob hauv kev pabcuam rau hnub no.
Tus tsim muaj xws li ib lub tog raj kheej carbureted ob-stroke engine. Cua txias - huab cua, ua haujlwm ntim yog 94 cubic meters. saib Nco ntsoov tias tus lej ntsuas hauv lub npe txhais tau tiaszog hauv horsepower. Yog li, Druzhba-4 chainsaw tau nruab nrog lub cav 4 l / s, thiab cov qauv nrog "E" Performance index yog nruab nrog lub tshuab hluav taws xob niaj hnub tshaj plaws hauv lub sijhawm ntawd. Cov pab pawg piston yog lubricated nrog roj yav tas los yaj hauv cov roj sib tov. Ua tsaug rau qhov yooj yim mounting ntawm lub cav, nws hloov nyob rau hauv cov ntaub ntawv ntawm kev xav tau tsis yog tshwj xeeb yog nyuaj.
Txawm hais tias lub tshuab hluav taws xob antediluvian lubrication ntawm chav tsev fais fab, nws yog nyob rau ntawm cov saws no tias cov cuab yeej ntawm kev ywj pheej pom bar lubrication tau siv thawj zaug, uas ua rau cov cuab yeej ua haujlwm tau zoo. Tsis tas li ntawd, thaum kawg nws tuaj yeem siv cov saw saw nrog cov hniav sib txawv. Tag nrho cov Druzhba chainsaws yog nruab nrog ib tug txhim khu kev qha thiab yooj yim inertial clutch.
Vim qhov no, thaum lub saw yog overloaded los yog lub log tsheb raug tom hauv ib tsob ntoo, thaum lub cav ceev poob qis heev, nws txoj kev txuas nrog cov saw hlau yog tam sim ntawd tawg, uas tsis txhob nres nws thiab ua rau lub cuab yeej nws tus kheej. Nyob rau hauv ntau txoj kev, nws yog precisely vim hais tias ntawm lawv simplicity thiab kev ruaj ntseg uas lawv tseem siv los ntawm ntau lab tus tib neeg nyob rau hauv ib ncig ntawm lub qub USSR. Tsis tas li ntawd, lub npe ntawm Druzhba chainsaw tau dhau los ua lub npe tsev neeg tiag tiag, thiab hauv qee lub tebchaws ntawm CIS qub, cov roj av pom tau hu ua qhov ntawd.
Hmoov tsis zoo, qhov hnyav ntawm qhov ntsuas yog tiag tiag epic thiab yog 12 kg. Tab sis thaum ua hauj lwm nyob rau hauv tsis nyuaj heev tej yam kev mob, yuav luag txhua yam roj thiab cov roj uas tsis muaj roj yuav muab nchuav rau hauv nws. Yog li, lub zog hluav taws xob tuaj yeem ua haujlwm ntsiag to txawm nyob rauqis octane roj. Thawj zaug, ib qho inertial nres tau siv, uas ua rau kom muaj kev nyab xeeb ntawm nws siv. Yog vim li cas Druzhba-4m chainsaw tau dhau los ua ntau yam ntawm cov kws tshaj lij.
Qhov no kuj tau pab txhawb rau qhov chaw ntawm kev tswj hwm. Txawm hais tias qhov kev npaj no txawv txawv, hnub no nws yuav tso cai rau koj pom cov pob tw loj thaum sawv ntsug, thaum nrog ntau cov saws niaj hnub koj yuav tsum txhos caug ua qhov no. Yog tias koj saib xyuas cov saws me me, ces nws tuaj yeem ua haujlwm txog 30 xyoo yam tsis muaj teeb meem tshwj xeeb. Nrog nws, koj tuaj yeem tsis tsuas yog poob hauv hav zoov xwb, tab sis kuj tau sau cov ntoo uas zoo nkauj heev.
