Tam sim no, kev sib txuas lus kev tsheb ciav hlau tau tsim muaj zog heev. Kev thauj neeg caij tsheb, xa khoom lossis xa ntawv yog kev lag luam uas siv tas li thiab txhua qhov chaw. Txawm li cas los xij, txhawm rau kom txhua yam ua haujlwm zoo li lub sijhawm ua haujlwm, nws yog ib qho tsim nyog los saib xyuas cov xwm txheej ntawm txhua lub tsheb thiab nws cov khoom.

Device

Lub thawv qag yog ib qho ntawm cov khoom siv khiav ntawm lub tsheb. Lub hom phiaj ntawm qhov no yog txhawm rau hloov tag nrho cov khoom thauj los ntawm lub tsheb mus rau lub caj dab qag. Nyob rau tib lub sijhawm, chav tsev no yog tsim los kom haum rau cov khoom siv lubricating thiab lubrication nws tus kheej. Tsis tas li ntawd, qhov no yog ib qho kev sib txuas ntawm lub wheelset thiab lub bogie ncej, lub rooj sib txoos tiv thaiv lub caj dab los ntawm kev sib kis los yog kev puas tsuaj. Thiab qhov kawg ua haujlwm uas cov nodes ua yog txwv qhov kev ncua ntev lossis kev hloov pauv ntawm tus khub txheeb ze rau lub laub.

Nws tseem ceeb heev uas yuav tsum nco ntsoov tias cov node yog unsprung thiab yog li ntawd nws yuav theej harshly perceive ib dynamic vibrations emanating los ntawm tus khiav, uas yuav twv yuav raug hu tshwm sim vim lub zog ntawm lub tsheb.

Sib dhos nrog bearings

Tam sim no, muaj ntau ntau hom axleboxes. Muaj cov ntsiab lus nrogbearings, uas tau muab faib ua ob pawg precisely raws li cov ntsiab lus no. Muaj cov nodes nrog cylindrical thiab spherical roller. Tam sim no, ob hom axleboxes nrog cov hom bearings yog siv thoob plaws hauv CIS.

Nws yog ib qho tsim nyog sau cia tias kev tsim cov khoom siv no nrog cov kheej kheej tsis tau ua txij li xyoo 1964, thiab tam sim no tsuas muaj li 5% ntawm cov tsheb ciav hlau uas nws lub tsheb muaj cov nodes nrog cov cuab yeej no. Tsis tas li ntawd, thaum cov khoom no ua tsis tiav, lawv tau hloov pauv tsis yog cov zoo sib xws, tab sis nrog cov chav nyob nrog cov kabmob cylindrical, yog li qhov feem pua me me no pheej yig zuj zus.

Tam sim no, hom axlebox tseem ceeb yog ib qho uas muaj cylindrical roller hom bearing ntawm qhov kub ncua kev kawm.

Cov menyuam bearings

Hnub no, txhua yam ntawm cov neeg caij tsheb thiab cov tsheb thauj khoom tau nruab nrog cov menyuam bearings. Tsis tas li ntawd, tag nrho cov neeg caij tsheb qub thiab yuav luag tag nrho (kwv yees li 80%) cov tsheb thauj khoom tau raug xa los ntawm cov qauv qub mus rau cov menyuam yaus. Tsis tas li ntawd, txij li xyoo 1982, tag nrho cov axlebox units ntawm lub tsheb tau nruab nrog cov menyuam hom. Qhov kev txiav txim siab no yog kev ncaj ncees los ntawm qhov tseeb tias qhov zoo thiab kev ntseeg siab ntawm kev ua haujlwm ntawm hom no yog siab dua li ntawm cov kabmob dawb. Qhov no yog pom tseeb yog tias peb coj mus rau hauv tus account xws li qhov taw qhia raws li qhov kev ncua lossis kev tsis sib txuas ntawm cov wagons vim cua sov ntawm qhov no. Kev xyaum tau pom tias cov menyuam cov ntsiab lus kub txog ib nrab ntau npaum li lawv cov khoom qub dhau los. Lwm qhov zoo ntawm lub logqag lub thawv nruab nrog cov menyuam bearings, nyob rau hauv hais tias lawv txo qhov tshwj xeeb kuj ntawm tag nrho lub tsheb los ntawm 7-10 units nyob rau lub caij thaum lub tsheb ciav hlau pib tsiv. Thiab kev siv roj lossis hluav taws xob siv los ntawm lub tsheb ciav hlau yuav raug txo los ntawm 10%.

Neeg nrog caij tsheb sib dhos

Tam sim no, ib lub thawv qag rau cov neeg caij tsheb kuj tseem siv, uas cov bearings tau nrawm los ntawm lub tshuab ntxhua khaub ncaws. Txhawm rau kom ua tau raws li cov txheej txheem ua tau zoo ntawm cov cuab yeej ntawm lub thawv ntawm lub tsheb thauj khoom lossis cov neeg caij tsheb, nws yog ib qho tsim nyog yuav tsum ua raws li cov txheej txheem rau kev txhawb nqa bogie thav duab ntawm ib qho tshwj xeeb. Nws tseem tsim nyog sau cia tias lub cev rau qhov no tuaj yeem ua rau ntau txoj hauv kev. Kev tsim khoom tuaj yeem ua tiav nrog kev txhawb nqa brackets, nrog rau cov khoom labyrinth, lossis nrog ob peb lub puab tsaig, thiab qhov labyrinth yuav raug nias.

Knot installation

Yuav kom ua tiav kev teeb tsa ntawm lub thawv axle sib dhos nrog cov menyuam cov kabmob, nws yuav tsum ua qee yam haujlwm ua ntej. Cov haujlwm no suav nrog kev tshawb nrhiav lub nplhaib tsim labyrinth, nrog rau cov kabmob lawv tus kheej. Cov yam ntxwv tseem ceeb uas lub nplhaib raug xaiv yog cuam tshuam, uas yog, nws yog qhov sib txawv ntawm qhov zoo ntawm qhov sib txawv ntawm qhov sib txawv ntawm txoj kab uas hla ntawm qhov tsaws sab hauv thiab txoj kab uas hla ntawm lub pre-hub ib feem ntawm lub qag no. Qhov ntsuas no yuav tsum nyob hauv thaj tsam ntawm 0.08mm txog 0.15mm. Kev xaiv ntawm cov menyuam bearings yuav tsum tau ua raws li qhov nruj, tab sis txoj kab uas hla ntawm lub nplhaib puab yog qhov tseem ceeb ntawm no. Parameter yuav tsumnyob rau hauv qhov ntau ntawm 0.04mm txog 0.065mm. Nws tseem yog ib qho tseem ceeb ntawm no kom coj mus rau hauv tus account lub axial clearance thiab qhov txawv ntawm cov radial sawv daws yuav, qhov taw qhia uas yuav tsum tau sib npaug zos rau 0.2 hli.

txheej txheem sib dhos pib nrog qhov tseeb tias nws yuav tsum tau ua kom sov lub nplhaib labyrinth mus rau qhov kub ntawm 125-150 degrees Celsius. Lub nplhaib yog ntsia rau ntawm qhov pre-hub ib feem ntawm lub qag. Tom ntej no, koj yuav tsum tau tos kom txias kom tiav thiab, siv ib tug nkhaus square, xyuas lub perpendicularity ntawm installation. Nws tseem yuav tsum tau siv lub ntsuas ntsuas ntsuas kom paub meej tias lub nplhaib tau zaum zoo. Tom qab ntawd, lawv mus rau lub installation ntawm lub khob qhia, uas yog screwed mus rau lub qag xov thiab yog tsim los tiv thaiv nws los ntawm kev puas tsuaj uas tej zaum yuav tshwm sim los ntawm ntxiv installation ntawm lub puab bearing rings.

Cassette bearings

Tam sim no, yog tias peb tig mus rau cov teb chaws Europe, tom qab ntawd hauv lawv cov tsheb ciav hlau ceev ceev axlebox units nrog ob-kab tapered roller bearings raug teeb tsa. Qhov ceev ntawm kev txav ntawm cov tsheb no yog nyob rau hauv thaj tsam ntawm 200 txog 350 km / h. Kev siv dav dav ntawm cov kabmob cassette tau dhau los ua qhov tseeb vim tias lawv muaj ntau qhov zoo hauv qab no:

• Txhim kho rau qib siab ua ke ua ke. Nyob rau hauv lem, qhov no muab ntau mileage uas lub tsheb ciav hlau mus, thiab kuj guarantees 100% kev khiav hauj lwm ntawm lub tsheb ciav hlau nyob rau hauv tag nrho cov warranty lub sij hawm, yog hais tias lub axles lub thawv raug tshuaj xyuas raws sij hawm.
• hom bearings no kiag liua tau raws li qhov yuav tsum tau ua kom ua tiav lub tsheb ciav hlau siab ceev.
• Tus qauv tsim ntawm cov qauv sib dhos no yog ntau compact.

Wheelset

Yuav kom lav kev nyab xeeb, nws yog ib qho tsim nyog yuav tsum tau xyuas lub sijhawm ua haujlwm ntawm lub thawv qag thiab lawv cov khub. Nws yog ib qho tseem ceeb kom paub tias thaum thawj qhov kev tshuaj xyuas ntawm ob khub thiab yog tias nws tsim nyog los zom nws, qhov no tuaj yeem ua tiav yam tsis tas yuav tshem lub axles. Yog tias, tom qab ua tiav qhov kev ua haujlwm no, qhov tsis xws luag tshwm sim dua los ntawm kev tshuaj xyuas tom ntej, uas yuav tsum tau muab tshem tawm los ntawm kev tig cov khub, tom qab ntawd nws tsis tuaj yeem ua yam tsis tau tshem lub axles.

Tom qab kev kho tiav lossis cov txheej txheem ntawm kev kuaj xyuas lub log ua tiav, nws yog xim dub. Nws tseem tsim nyog sau cia tias qhov sib txuas ntawm cov hubs nrog lub hub axles kuj tau pleev xim rau, tab sis twb tau pleev xim rau. Xim yog ua nyob ib ncig ntawm tag nrho cov ncig ntawm qhov sib koom ua ke.

Nyob zoo

Tam sim no, peb txoj hauv kev haum cov kabmob ntawm lub qag yog paub thiab siv - kub, tes tsho, nias. Txawm li cas los xij, nyob rau hauv niaj hnub axleboxes, tsuas yog ob ntawm peb txoj kev siv - kub thiab nias.

Nws tseem ceeb heev uas yuav tsum paub tias thaum ua tiav cov txheej txheem sib dhos ua tiav, lub rooj sib txoos tau ntim cov roj. Yog hais tias peb tham txog lub lubricant uas yog siv rau cov menyuam bearings, ces txij thaum pib ntawm 1973 nws yog LZ-TsNII. Lub hom phiaj tseem ceeb ntawm qhov sib tov no suav nrog cov haujlwm xws li: muabtsis kam hnav, corrosion, kom ntseeg tau tias tsis muaj scuffing phenomena uas tshwm sim thaum lub sij hawm ua hauj lwm ntawm cov kabmob.
