Sib npaug shafts ntawm lub cav, lub hom phiaj thiab cov khoom siv

Thaum lub sijhawm ua haujlwm ntawm crank mechanism, inertial rog inevitably tshwm sim. Lawv tuaj yeem muab faib ua qhov sib npaug thiab tsis sib npaug. Kev txav ntawm cov pistons ua rau muaj kev vibrations thiab suab nrov. Txhawm rau tshem tawm qhov tsis sib xws, lub flywheel thiab crankshaft tsis txaus. Yog li ntawd, manufacturers nruab ib tug balancer shafts.

Lub hom phiaj ntawm kev sib npaug shafts

Lub luag haujlwm tseem ceeb uas sib npaug shafts ua yog tshem tawm qhov tsis sib xws thiab txo kev co. Qhov teeb meem no tau dhau los ua qhov tshwj xeeb rau cov tshuab muaj zog. Txoj kev loj hlob ntawm cov motors nrog lub ntim ntawm ntau tshaj 2 litres tau ua rau muaj zog kev co. Txhawm rau tshem tawm qhov teeb meem no, cov kws tsim khoom txiav txim siab siv cov khoom sib npaug.

Hauv qhov no, qhov chaw ntawm lub tog raj kheej yuav tsum raug coj mus rau hauv tus account. Cov neeg tsim khoom siv 3 layout schemes.

  1. Lub tog raj kheej tuaj yeem nyob hauv tib lub dav hlau.
  2. Ib txoj kev sib txawv kiag li yog suav tias yog ntau heev, nyob rau hauv uas cov axes ntawm lub tog raj kheej yog qhia nyob rau hauv opposite lus qhia.
  3. Muaj ib qho system uas muab rau kev siv cov v-shaped scheme.

Qhov zoo ntawm qhov ntsuas yog nyob ntawm qhov kev teeb tsa ntawm lub tog raj kheej. Txhawm rau tshem tawm qhov tsis sib xws, qhov sib npaug ntawm cov ncej yog siv, uas yog cylindrical rods. Cov ntsiab lus no tau nruab rau hauv 2 daim ntawm txhua sab ntawm lub crankshaft. Gears yog siv los txuas qhov chaw. Ua li no, qhov system tuaj yeem sib npaug. Balance shafts tuaj yeem txo qhov kev vibration thiab suab nrov.

Yuav ua li cas nws ua hauj lwm

Sib npaug shafts ntawm lub cav, lub hom phiaj thiab cov khoom siv

Txhawm rau them nyiaj rau lub zog, cov springs yog siv, uas nyob rau hauv lub zog tsav. Yog vim li cas rau qhov nce hnav ntawm cov nodes tej zaum yuav ntxiv load txuam nrog qhov tshwm sim ntawm malfunctions. Qhov loj tshaj plaws loads ntog ntawm lub tiaj bearings, uas kis tau los ntawm lub crankshaft. Tus tswv tsheb raug qhia kom hu rau lub chaw pabcuam, thiab tsis kho qhov tsis raug ntawm lawv tus kheej.

Tsav hom

Qhov ntsuas qhov system yog tsav los ntawm cov saw hlau los yog cov hniav siv. Cov ncej vibrations tuaj yeem txo qhov no. Tsis tas li ntawd, manufacturers nruab ib lub caij nplooj ntoos hlav damper nyob rau hauv lub tsav.

Thaum twg yog qhov sib npaug shafts invented?

Lub tswv yim ntawm kev qhia txog kev sib npaug shafts belongs rau Mitsubishi. Lub novelty yog thawj zaug siv nyob rau hauv 1976. Kev txhim kho kev lag luam tau nrov heev vim nws tso cai rau txo kev vibrations thiab suab nrov. Nrog kev pab los ntawm balancer shafts, nws muaj peev xwm mus nce lub engine peev xwm. Lub sijhawm no, cov tshuab muaj zog pib tsim, uas muaj qhov ntim ntawm 2 litres. Txawm li cas los xij, thaum lub sijhawm ua haujlwm muaj kev vibration muaj zog. Nyob rau hauv lub neej yav tom ntej, lwm manufacturers txiav txim siab los siv txoj kev loj hlob.

Cov yam ntxwv ntawm kev hloov qhov sib npaug shafts

Cov loads uas tshwm sim thaum lub sijhawm ua haujlwm muaj qhov tsis zoo rau cov kabmob. Hloov cov node yog kim heev. Yuav kom txuag tau nyiaj, cov tswv tsheb raug yuam kom rhuav tshem cov ncej thaiv. Plugs yog siv los tiv thaiv threaded kev sib txuas thaum lub sij hawm kho. Thaum tsis muaj qhov sib npaug ntawm cov ncej, lub cav ua haujlwm raug cuam tshuam. Kev vibrations thiab suab nrov tshwm nyob rau hauv lub tshuab fais fab. Qhov degree ntawm qhov tsis sib xws ncaj qha nyob ntawm cov yam ntxwv ntawm lub cav. Koj tuaj yeem sib npaug ntawm qhov system los ntawm kev siv cov khoom sib npaug. Txhawm rau ua qhov no, nws yog ib qho tsim nyog los hloov cov qauv tsim ntawm lub cav. Txawm li cas los xij, qhov kev txiav txim siab no yuav cuam tshuam rau lub sijhawm ntawm lub cev muaj zog.

Sib npaug shafts ntawm lub cav, lub hom phiaj thiab cov khoom siv

Yog vim li cas rau qhov tshwm sim ntawm cov suab nrov tuaj yeem ua haujlwm tsis zoo ntawm cov khoom thiab cov khoom sib dhos. Yog li ntawd, tus tswv tsheb yuav tsum tam sim ntawd hu rau lub chaw pabcuam. Tsis kho yuav ua rau muaj teeb meem loj. Cov suab nrov nrov tuaj yeem yog vim qhov tsis ua haujlwm ntawm cov ncej sib dhos lossis siv txoj hlua tawg. Lub suab nrov thiab kev vibration tuaj yeem tshwm sim vim hnav bearings. Malfunctions cuam tshuam rau kev ua haujlwm ntawm tag nrho lub cav.

Txhawm rau tshem tawm qhov tsis xws luag, nws yog ib qho tsim nyog los hloov cov balancing shafts. Rau lub hom phiaj no, cov tswv tsheb yuav tsum hu rau lub chaw pabcuam. Lub zeem muag ntawm kev hloov kho loj tsis zoo li yuav rov hais dua rau cov neeg tsav tsheb. Yog li ntawd, nws yog ib qho tsim nyog los txheeb xyuas qhov ua rau muaj kev vibration thiab suab nrov raws sijhawm. Txhawm rau tiv thaiv lub qhov los ntawm kev puas tsuaj, cov kws tshaj lij siv cov plugs. Qhov tsis muaj cov nyiaj them poob haujlwm tuaj yeem ua rau qhov tsis sib xws ntawm lub cev muaj zog. Nyob rau hauv cov ntaub ntawv no, cov tswv tsheb raug yuam kom pom zoo rau tag nrho dismantling ntawm chav tsev. Kev ua tsis tau zoo tuaj yeem ua rau poob ntawm lub cav ua haujlwm.

Qhov ua rau lub suab nrov nrov hauv lub tshuab fais fab tuaj yeem yog qhov tsis ua haujlwm ntawm qhov chaw. Yog li ntawd, cov neeg tsav tsheb yuav tsum ua raws li cov cai hauv qab no:

  1. Kev tsav tsheb hnyav tuaj yeem ua rau cov khoom hnav.
  2. Txhawm rau txo cov load ntawm lub zog ntawm lub shafts, nws yog ib qho tsim nyog yuav tsum tau ua haujlwm hauv lub sijhawm.
  3. Tus tswv lub tsheb yuav tsum hloov cov roj raws sijhawm.
  4. Yog tias tsim nyog, txoj siv tawv lossis cov saw hlau yuav tsum tau hloov. Qhov sib npaug shafts yuav tsum tig yam tsis muaj kev thauj khoom ntxiv.
