Oob khab Kumasi: piav qhia, ntaus hom, thiab xyuas

Yuav ua li cas ua lub cav mus rau hauv lub lag luam, nws yuav tsum tau khiav. Rau lub hom phiaj no cov ntaus ntawv yog muab nyob rau hauv ib lub tsheb oob khab. Kamaz Euro-3 yog tseem txawm peem rau nrog lawv. Lub mechanism yuav ua tau ntau hom. Zoo, cia saib yuav ua li cas lub oob khab Kamaz yuav ua li cas nws ua hauj lwm thiab dab tsi yog qhov kev yam ntxwv.

hom

Muaj ob peb hom ntawm cov mechanisms:

• Iav.
• Gearless.

Oob khab KamAZa koom mus rau tus thawj hom kiag li lawm. Qhov no mechanism yog lub feem ntau haib, vim hais tias muaj yog torque kis tau tus mob los ntawm cov thauj tog rau nkoj rau ntawm lub iav reducer nqa. Cov starters muaj tsis tsuas muaj hwj chim, tab sis kuj yog ib tug zoo starting torque. lawv kuj muaj ib tug ntev kev pab cuam lub neej. Cov starters yog siv los ntawm 90 feem pua ntawm cov hnub no lub tsheb.

Hais txog gearless hais, lawv khiav lag luam raws li nram no. Thaum tau txais daim ntawv ntawm cov voltage mus rau lub electromagnetic mus, thiab txav Bendix iav txhawb cov tub ntxhais lub crown log. Tam sim no ntws mus rau hauv lub thauj tog rau nkoj. Ib tug kev sib hloov. Lub pinion ncej haum ua ke ua tsaug rau lub overrunning clutch. Tom qab ib tug muaj kev vam meej pib ntawm lub cav, qhov no compound yog txo. Lub hwj chim mov yog nres, thiab cov iav yog rov qab mus rau nws cov thawj txoj hauj lwm. Vim cov uas tsis muaj hauj lwm zoo thiab tsis muaj maintainability, gearless ntsiab suab siv nyob rau hauv lub tsheb lag luam.

ntaus ntawv

Structurally Kamaz oob khab yog ib tug hluav taws xob motor nrog lub traction relay thiab ib tug txhua yam tsav. Mounted rau lub active mechanism ntawm lub flywheel tsev nyob (nyob rau sab laug sab ntawm lub engine). Nws fastened nyob rau hauv peb bolts nrog studs.

Lub mechanism yog raws li nyob rau hauv ib tug 4-ncej lub cev muaj zog nrog series excitation. Tsis tas li ntawd nyob rau hauv ib tug oob khab qauv muaj xws li cov nram qab no hais:

• tus tsav ncej.
• Thauj tog rau nkoj.
• Tsheb thiab pem hauv ntej npog.
• Collector.
• Lub txhuam los ua ke.
• Retractor relay Kamaz oob khab.
• Lub excitation winding.

Tag nrho cov no yog ua ke nyob rau hauv ib tug hlau enclosure. Externally oob khab Kamaz zoo raws li qhia nyob rau hauv cov kev yees duab hauv qab no.

Lub tsev nyob yog ua los ntawm me me hlau. Nws ua hauj lwm pab raws li ib tug sib nqus Circuit Court, qhov twg lub cores yog mounted. Lub tsev nyob hau. Rov qab hides txhuam los ua ke. Lub pem hauv ntej - tsav mechanism. Lub exciting winding yog muab faib mus rau hauv thaum uas tig mus tej ceg uas siv series-kev cob cog rua coils. Raws li siv winding tooj liab hlau nrog ib lub ntoo khaub lig seem. Ib kawg txuas mus rau lub zoo txhuam thiab lub thib ob - mus rau lub Cais vaj tse nyob.

Tag nrho coils yog impregnated nrog tshwj xeeb lacquer thiab ntxiv braided paj rwb daim kab xev. Lub coils yog insulated cable ntawv.

thauj tog rau nkoj

Raws li rau lub anchors, cov nram no muaj nyob rau hauv nws:

• Ncej nrog ib tug proofreader.
• Winding.
• Core.

Xeem ua los ntawm hluav taws xob steel los xij. Lub collector yog tsim kom muaj ib tug tsis tu ncua torque. Winding - yoj hom. Lub grooves yog muab tso rau hauv cov tub ntxhais hlau 2.

Ntxiv mus, lawv windings yog insulated los ntawm cov tub ntxhais. Qhov kawg ntawm hlau yog pw nyob rau hauv lub qhov ntawm ib tug tooj liab phaj thiab lub collector yog welded.

txhuam

Qhov no ua ke muab ib lub mov voltage mus rau lub collector phaj. Txhuam tuav tseg yog dielectric lub tes tsho nrog hlau inserts. Cov yav tas yog nyob rau hauv lub txhuam. Mob yog welded rau tus ncej phiaj los chaw welding. Qhov no lub caij yog tus Tsov tus tw ib feem ntawm lub teb winding. Txhuam lawv tus kheej no yog ua los ntawm ib tug hlau lead, tooj liab thiab graphite. Tsis tas li ntawd, cov muaj pes tsawg leeg ntawm lub ntxiv tin. Qhov no alloy tsis pub cov voltage nco nyob rau hauv lub winding thiab thiaj li hnav rau lub collector.

Yuav ua li cas nws ua hauj lwm

Tom qab ignition tseem ceeb turnover voltage txhab khoom mus rau ntxiv (REYE-530) oob khab relay. KamAZ yog tseem sawv tseem. Thaum cov voltage tshaj 8 bar, traction relay los rau hauv lub lag luam.

Lub mechanism forcibly txuas tus tsav iav nrog lub flywheel. Tsis tas li ntawd lub sij hawm no, lub hwj chim cov neeg uas lub oob khab. Cov thauj tog rau nkoj pib tig. Torque yog kis tau mus rau lub flywheel. Thaum lub cav pib, lub iav txiav disengages.

kev yam ntxwv

Freight tsheb KamAZ ntsia oob khab St-142b. Nws muaj cov nram qab cov yam ntxwv:

• Voltage - 24 volts.
• Nyob hwj chim - 7.7 kW los yog 10.5 hp.
• Voltage yuav pab kom cov retractor relay - 8 volts.
• Lub siab ntawm tus txhuam springs - 2 kgf.
• Lub qhov siab ntawm tus txhuam - 19-20 millimeters.
• Tam sim no siv - 130 Amp.
• Turnovers thauj tog rau nkoj rau ntawm kaw - 5500 ib feeb.

Oob khab (Kamaz): nqe

Lub lag luam muaj ntau ntawm ob tshiab thiab remanufactured starters.

Yuav ua li cas yog nyob rau hauv oob khab (Kamaz) nqi? St-hom ntaus ntawv 142b yuav raug muas raws li tsawg li 4.5 mus rau 13 txhiab rubles.

Tej kev yuam kev thiab kho oob khab

Kamaz - heev maintainable tsheb. Yog hais tias teeb meem tshwm sim, koj yuav tau tshem tawm cov kev puas tsuaj rau koj tus kheej. Xav txog cov raug teeb meem nrog oob khab St-142b:

1. Thaum lub ignition ntaus ntawv yog tsis txhais. Nyob rau hauv cov ntaub ntawv no, koj yuav tsum khij lub winding ntawm lub traction relay. Tej zaum tsis muaj ib tug luv luv Circuit Court los yog qhib Circuit Court. Nyob ntawm seb qhov xwm ntawm tus tsis ua hauj lwm yuav tsum tau hloov lub retractor. Tsis tas li ntawd ua rau failures yuav ua raws li cov tsis muaj ntawm kev sib cuag ntawm cov txhuam thiab commutator. Nyob rau hauv cov ntaub ntawv no, mus saib tus txhuam siab springs. Yog hais tias nws yog tsawg tshaj li 1.8 kg, lub caij hloov mus rau ib lub tshiab.
2. Nws tsis ua hauj lwm rau hauv lub traction relay. Koj yuav tau mus xyuas lub winding ntawm lub ntxiv relay thiab kom paub tseeb tias lub sam xeeb ntawm lub pull-nyob rau hauv kauj. Tsis tas li ntawd mus saib cov ntseeg ntawm cov kev sib cuag nyob rau hauv lub Circuit Court thiab tag nrho cov kev sib txuas.
3. Thaum lub oob khab tshwm clicks ntawm tus ntxiv relay. Tus tsav iav nyob rau flywheel seizes lub crown. Tej zaum yog vim li cas cov lus dag nyob rau hauv lub tsis ncaj ncees lawm mus ob peb vas rau ntawm lub caij Circuit Court ntawm lub traction relay hu. Yuav ua li cas mus kho tau nws? Cov kis muab ntawm cov iav thiab cov thrust washer. Tom ntej no, mus saib rau ntawm lub lag luam ntawm lub mechanism. Yog hais tias cov tsos mob recur, tej zaum, twb tau hammered los ntawm tus kawg ib feem ntawm ib tug oob khab tsav hniav los yog flywheel. Daws tau qhov teeb meem nyob rau hauv ob peb txoj kev. Tus thawj - los cov hniav nrog rau cov kev pab los ntawm welding. Qhov thib ob - los hloov lub flywheel nplhaib iav los yog tsav. Qhov thib peb txoj kev yuav tu irregularities rau ntawm cov hniav.
4. Thaum lub sij hawm lub lag luam, lub thauj tog rau nkoj yog rotated, tab sis tsis koom nrog lub flywheel. Lub crankshaft tsis tig. Nyob rau hauv no qhov teeb meem no, koj xav mus saib kev ncaj ncees ntawm lub flywheel hniav thiab tus tsav iav. Tsis tas li ntawd ua ib tug re-haum ntawm lub oob khab.

xaus

Yog li ntawd, peb pom hais tias ib tug oob khab yog Kamaz, uas muaj cov kev yam ntxwv thiab tej kev yuam kev. Raws li koj tau pom, qhov no yog ib tug heev mechanism. Yog hais tias ib qho teeb meem tshwm sim (los yog cov tsos mob), nws yuav tsum tau ua thaum muaj xwm ceev kho vaj tse. Txwv tsis pub, pib lub cav koj yuav tsis vam meej.
