Ukudluliswa kogandaganda be-MTZ kusebenzisa okuhlukile kwendabuko kanye namagiya okugcina adlulisa i-torque emasondweni noma kuma-gearbox amasondo asebenzisa ama-axle shafts.Funda konke mayelana namashafti okugcina e-MTZ, izinhlobo zawo nemiklamo, kanye nokukhetha kwawo nokushintshwa kwawo kulesi sihloko.
Iyini i-shaft yokugcina ye-MTZ?
I-shaft yokugcina ye-MTZ (i-drive axle differential shaft) iyingxenye yokudluliswa kogandaganda abanamasondo abakhiqizwe yi-Minsk Tractor Plant;ama-shaft adlulisa i-torque isuka kumehluko we-axle iye emasondweni (ku-asili yangemuva) noma kumashafu aqondile namasondo (kwi-axle yokushayela yangaphambili, i-PWM).
Ukudluliswa kwemishini ye-MTZ yakhiwe ngokohlelo lwe-classical - i-torque esuka enjini ngokusebenzisa i-clutch kanye ne-gearbox ingena e-axle yangemuva, lapho iqala ukuguqulwa khona ngegiya eliyinhloko, idlula ngokuhlukana komklamo ojwayelekile, futhi ngokusebenzisa igiya lokugcina lingena emasondweni okushayela.Amagiya ashayelwa okokugcina axhumeke ngqo kuma-axle shafts adlulela ngale kwendlu yokudlulisa futhi athwale amahabhu.Ngakho-ke, i-axle shafts yangemuva ye-MTZ yenza imisebenzi emibili ngesikhathi esisodwa:
- Ukudluliswa kwe-torque kusuka egiyeni lokugcina kuya esondweni;
- Ukuqiniswa kwamasondo - ukubamba kwayo nokulungiswa kuzo zombili izindiza (umthwalo usatshalaliswa phakathi kwe-axle shaft kanye ne-casing yayo).
Kuwo wonke amasondo ukuguqulwa kogandaganda we-MTZ, kusetshenziswa ama-PWM omklamo ongajwayelekile.I-torque esuka ku-gearbox ngokusebenzisa ikesi yokudlulisa ingena egiyeni elikhulu kanye nomehluko, futhi isuka kuyo idluliswa ngama-axle shafts iye kuma-vertical shafts kanye ne-wheel drive.Lapha, i-axle shaft ayinakho ukuxhumana okuqondile namasondo okushayela, ngakho-ke isetshenziselwa ukudlulisa i-torque kuphela.
Ama-axle shafts e-MTZ adlala indima ebalulekile ekusebenzeni okuvamile kokudlulisela, ngakho noma yiziphi izinkinga ngalezi zingxenye ziholela enkingeni noma ekungenzeki ngokuphelele kokusebenza kukagandaganda.Ngaphambi kokufaka ama-axle shafts, kuyadingeka ukuqonda izinhlobo ezikhona, ukwakheka kanye nezici.
Izinhlobo, ukwakheka kanye nezici ze-MTZ final drive axle shafts
Wonke ama-axle shafts we-MTZ ahlukaniswe ngamaqembu amabili ngokwenhloso yawo:
- Ama-axle shafts angaphambili (PWM), noma ama-axle shafts angaphambili;
- Ama-axle shafts wedrayivu yokugcina ye-asi yangemuva, noma ama-axle shafts angemuva.
Futhi, imininingwane ihlukaniswe ngamaqembu amabili emvelaphi:
- Okwangempela - okukhiqizwe yi-RUE MTZ (Isitjalo sikagandaganda saseMinsk);
- Okungeyona eyangempela - ekhiqizwa amabhizinisi ase-Ukraine i-TARA ne-RZTZ (PJSC "Romny Plant" Traktorozapchast "").
Ngakolunye uhlangothi, uhlobo ngalunye lwe-axle shafts lunezinhlobonhlobo nezici zalo.
I-MTZ shaft ye-axle ye-axle yangaphambili
I-axle shaft ye-PWM ithatha indawo emzimbeni ovundlile webhuloho phakathi komehluko kanye ne-shaft eqondile.Ingxenye inomklamo olula: i-shaft yensimbi ye-cross-section eguquguqukayo, ngakolunye uhlangothi kukhona ama-splines okufakwa ku-cuff yokuhlukanisa (i-semi-axial gear), kanti ngakolunye - igiya le-bevel ukuxhumana negiya le-bevel le-shaft eqondile.Ngemuva kwegiya, izihlalo ezinobubanzi obungu-35 mm zenzelwe ama-bearings, futhi kude kukhona intambo yokuqinisa i-nut ekhethekile ephethe iphakheji lama-bearings angu-2 kanye nendandatho ye-spacer.
Kusetshenziswa izinhlobo ezimbili zama-axle shafts kumagandaganda, izici zazo ezinikezwe etafuleni:
| Ikati le-axle shaft.inombolo 52-2308063 ("ifushane") | I-axle shaft cat.number 52-2308065 ("inde") | |
|---|---|---|
| Ubude | 383 mm | 450 mm |
| I-Bevel gear diameter | 84 mm | 72 mm |
| Inombolo yamazinyo e-bevel gear, Z | 14 | 11 |
| Uchungechunge lwenati lokukhiya | M35x1.5 | |
| Ububanzi bethiphu ye-spline | 29 mm | |
| Inani lezikhala zethiphu, Z | 10 | |
 |  | |
Ngakho-ke, ama-axle shafts ayahluka ngobude nezici zegiya le-bevel, kodwa womabili angasetshenziswa kuma-axles afanayo.I-axle shaft ende ikuvumela ukuthi ushintshe ithrekhi kagandaganda ngaphakathi kwemingcele emikhulu, futhi i-axle shaft emfushane ikuvumela ukuthi ushintshe isilinganiso sokugcina sokushayela kanye nezici zokushayela zikagandaganda.
Kumele kuqashelwe ukuthi lezi zinhlobo ze-axle shaft zisetshenziswa kumamodeli amadala namasha amatrakta we-MTZ (eBelarus), nawo afakwe kugandaganda ofanayo we-UMZ-6.
Ama-axle shafts enziwe ngezinsimbi zesakhiwo ezihlanganisiwe zamabanga 20HN3A kanye nama-analogue awo ngomshini wamabha anomumo noma ngokufoja okushisayo.
I-MTZ shaft ye-axle ye-axle yangemuva
Ama-axle shaft athatha isikhala ku-ekseli yangemuva kagandaganda, axhuma ngqo egiyeni lokugcina elishayelwa kanye nasezindaweni zamasondo.Kogandaganda besitayela esidala, i-axle shaft eyengeziwe ixhunywe kumshini wokukhiya ohlukile.
Ingxenye inomklamo olula: iyi-shaft yensimbi ye-variable cross-section, ngaphakathi lapho kuxhunywa i-spline eyodwa noma ezimbili, futhi ngaphandle kunesihlalo sokufakwa kwehabhu lamasondo.Isihlalo sinobubanzi obungaguquki kubo bonke ubude, ngakolunye uhlangothi sine-groove yokhiye wehabhu, futhi ngakolunye uhlangothi kune-rack enamazinyo yesibungu sokulungiswa kwehabhu.Lo mklamo awuvumeli kuphela ukulungisa ihabhu ku-axle shaft, kodwa futhi nokwenza ukulungiswa okungenasinyathelo kobubanzi bethrekhi yamasondo angemuva.Engxenyeni emaphakathi ye-axle shaft kukhona i-thrust flange kanye nesihlalo sokuthwala, lapho ingxenye igxile khona futhi ibanjwe emkhonweni we-axle shaft.
Njengamanje, kusetshenziswa izinhlobo ezintathu zama-axle shafts angemuva, izici zazo zivezwe etafuleni:
| I-axle shaft cat.number 50-2407082-A yesampula endala | I-axle shaft cat.number 50-2407082-A1 yesampula endala | I-axle shaft cat.number 50-2407082-A-01 yesampula entsha | |
|---|---|---|---|
| Ubude | 975 mm | 930 mm | |
| Ububanzi be-shank ngaphansi kwehabhu | 75 mm | ||
| Ububanzi be-shank bokuhlala egiyeni elishayelwayo ledrayivu yokugcina | 95 mm | ||
| Inani lama-shank splines okuhlala egiyeni lokugcina elishayelwa, Z | 20 | ||
| I-diameter shank yokukhiya okuhlukile komshini | 68 mm | I-shank ayikho | |
| Inombolo yemigqa ye-shank yokukhiya okuhlukile, Z | 14 | ||
Kulula ukubona ukuthi ama-axle shafts amamodeli amadala namasha ahluka ngemininingwane eyodwa - i-shank yendlela yokukhiya ehlukile.Emigodini ye-axle endala, le shank, ngakho-ke ekuqokweni kwabo kunenombolo yamazinyo awo womabili ama-shank - Z = 14/20.Emigodini emisha ye-axle, leli shank alisekho, ngakho-ke inani lamazinyo lichazwa ngokuthi Z = 20. Ama-axle shafts wesitayela esidala angasetshenziswa kumagandaganda amamodeli okuqala - MTZ-50/52, 80/82 kanye ne-100. /102.Izingxenye imodeli entsha ziyasebenza ogandaganda kokubili ukuguqulwa endala futhi entsha MTZ ( "Belarus").Kodwa-ke, kwezinye izimo, kwamukelekile ukushintshwa ngaphandle kokulahlekelwa ukusebenza nezici zokudlulisela.
Ama-axle shaft angemuva enziwe ngezinsimbi ze-alloy zesakhiwo 40X, 35KHGSA kanye nama-analogue awo ngomshini noma nge-hot forging.
Ungakhetha kanjani kahle futhi ubeke esikhundleni se-shaft yokugcina ye-MTZ
Kokubili ama-axle shafts angaphambili nangemuva ogandaganda be-MTZ angaphansi kwemithwalo ebalulekile ye-torsional, kanye nokushaqeka nokuguga kwama-splines namazinyo egiya.Futhi ama-axle shafts angemuva nawo angaphansi kwemithwalo egotshwayo, ngoba athwala sonke isisindo sangemuva kagandaganda.Konke lokhu kuholela ekugqokeni nasekuqhekekeni kwama-axle shafts, okuphazamisa ukusebenza kwawo wonke umshini.
Izinkinga ezivame kakhulu zama-axle shafts angaphambili ukugqoka nokubhujiswa kwamazinyo egiya le-bevel, ukugqokwa kwesihlalo esithwalayo kuze kufike kububanzi obungaphansi kuka-34.9 mm, ukuqhekeka noma ukuphuka kwe-axle shaft.Lokhu kungasebenzi kubonakaliswa ngomsindo othize ovela ku-PWM, ukubonakala kwezinhlayiya zensimbi emafutheni, futhi kwezinye izimo - ukugoqa amasondo angaphambili, njll. Ukwenza ukulungiswa, amathuluzi akhethekile ayadingeka ukuze ucindezele i-axle shaft ngaphandle kwendlu yayo. , kanye nokukhipha ama-bearings ku-axle shaft.
Izinkinga ezivame kakhulu ze-axle shafts yangemuva ukulimala kwe-slot, ukuguga kwe-groove yokukhiya ukhiye wehabhu kanye nomzila wesitimela wokulungisa, kanye nokuguqulwa nokuqhekeka okuhlukahlukene.Lokhu kungasebenzi kahle kubonakala ngokubukeka kokudlala kwamasondo, ukungakwazi ukufaka okuthembekile kwehabhu nokulungiswa kwethrekhi, kanye nokudlidliza kwamasondo ngenkathi ugandaganda uhamba.Ukuze uthole ukuxilonga nokulungiswa, kuyadingeka ukuqaqa isondo ne-hub casing, futhi ucindezele ukuphuma kwe-axle shaft usebenzisa i-puller.Umsebenzi kufanele wenziwe ngokuhambisana nemiyalelo yokulungisa ugandaganda.
Ukuze ushintshe, kufanele ukhethe lezo zinhlobo zama-axle shafts anconywe umkhiqizi kagandaganda, kodwa kwamukelekile ukufaka izingxenye zezinye izinombolo zekhathalogi.Ama-axle shaft angashintshwa eyodwa ngesikhathi, kodwa kwezinye izimo kunengqondo ukuwashintsha ufake ipheya ngesikhathi esisodwa, njengoba ukuguga kwamazinyo nezihlalo ezithwalayo kuzo zombili izinsimbi ze-axle kwenzeka cishe ngokuqina okufanayo.Lapho uthenga i-axle shaft, ama-bearings angadinga ukushintshwa futhi izingxenye ezintsha zokuvala (ama-cuffs) kufanele zisetshenziswe.Uma ushintsha i-axle shaft yangemuva, kunconywa ukusebenzisa iphinikhodi entsha ye-hub cotter futhi, uma kunesidingo, isibungu - lokhu kuzokwandisa impilo yengxenye.
Ngokukhetha okulungile nokushintshwa kwe-axle shaft yokugcina ye-MTZ, ugandaganda uzosebenza ngokwethembeka nangempumelelo kunoma yiziphi izimo.
