MTZ axle shaft ya drive yomaliza: ulalo wamphamvu pakupatsira thirakitala

Kutumiza kwa zida za MTZ kumamangidwa molingana ndi dongosolo lachikale - torque yochokera ku injini kudzera pa clutch ndi gearbox imalowa kumbuyo, komwe imasinthidwa koyamba ndi giya yayikulu, imadutsa kusiyanasiyana kwamapangidwe anthawi zonse, ndikudutsa zida zomaliza zimalowa m'magudumu oyendetsa.Magiya oyendetsedwa agalimoto yomaliza amalumikizidwa mwachindunji ndi ma axle shafts omwe amapitilira nyumba zotumizira ndikunyamula ma hubs.Chifukwa chake, kumbuyo kwa chitsulo cha MTZ kumagwira ntchito ziwiri nthawi imodzi:

• Kutumiza kwa torque kuchokera ku giya yomaliza kupita ku gudumu;
• Kumangirira kwa magudumu - kugwira kwake ndikukhazikika mu ndege zonse ziwiri (katunduyo amagawidwa pakati pa tsinde la chitsulo ndi thumba lake).

Pa magudumu onse oyendetsa mathirakitala a MTZ, ma PWM a mapangidwe osakhazikika amagwiritsidwa ntchito.Torque yochokera ku bokosi la gear kudzera muzotengera zosinthira imalowa mu giya yayikulu ndikusiyanitsidwa, ndipo kuchokera pamenepo imafalikira kudzera muzitsulo za axle kupita ku ma shaft oyima ndi ma wheel drive.Pano, shaft ya axle ilibe kulumikizana mwachindunji ndi mawilo oyendetsa, chifukwa chake imagwiritsidwa ntchito popereka torque.

Ma axle shafts a MTZ amatenga gawo lalikulu pakugwira ntchito kwapawiri, chifukwa chake mavuto aliwonse omwe ali ndi magawowa amabweretsa zovuta kapena kulephera kwathunthu kugwiritsa ntchito thirakitala.Musanayambe kusintha ma axle shafts, ndikofunikira kumvetsetsa mitundu yomwe ilipo, kapangidwe kake ndi mawonekedwe awo.

 

Mitundu, mapangidwe ndi mawonekedwe a MTZ final drive axle shafts

Ma axle shafts onse a MTZ amagawidwa m'magulu awiri malinga ndi cholinga chawo:

• zitsulo zoyendetsa kutsogolo (PWM), kapena zitsulo zakutsogolo;
• Ma axle shafts omaliza a axle yakumbuyo, kapena kungoyambira kumbuyo.

Komanso, tsatanetsatane amagawidwa m'magulu awiri oyambira:

• Choyambirira - chopangidwa ndi RUE MTZ (Minsk Tractor Plant);
• Osakhala apachiyambi - opangidwa ndi mabizinesi aku Ukraine TARA ndi RZTZ (PJSC "Romny Plant" Traktorozapchast "").

Komanso, mtundu uliwonse wa ma axle shafts uli ndi mitundu yake komanso mawonekedwe ake.

 

MTZ axle shafts ya kutsogolo kwa ekseli yoyendetsa

PWM axle shaft imakhala ndi malo opingasa a mlatho pakati pa tsinde losiyana ndi loyima.Gawoli lili ndi mapangidwe osavuta: ndi chitsulo chachitsulo cha magawo osiyanasiyana, mbali imodzi yomwe ili ndi ma splines oyika mu cuff ya masiyanidwe (semi-axial gear), ndi inayo - zida za bevel kulumikizana ndi zida za bevel za shaft yoyima.Kumbuyo kwa giya, mipando yokhala ndi mainchesi 35 mm imapangidwira mayendedwe, ndipo patali pali ulusi wolimbitsa nati wapadera wokhala ndi phukusi la 2 ndi mphete ya spacer.

Mitundu iwiri ya ma axle shafts imagwiritsidwa ntchito pa thirakitara, zomwe zimaperekedwa patebulo:

	Axle shaft mphaka.nambala 52-2308063 ("yachidule")	Axle shaft cat.number 52-2308065 ("yaitali")
Utali	383 mm pa	450 mm
Bevel gear m'mimba mwake	84 mm	72 mm pa
Chiwerengero cha mano a bevel gear, Z	14	11
Ulusi wa mtedza wokhoma	M35x1.5
Kutalika kwa nsonga ya spline	29 mm ndi
Chiwerengero cha nsonga zolowera, Z	10

 

Chifukwa chake, ma axle shafts amasiyana kutalika ndi mawonekedwe a zida za bevel, koma zonse ziwiri zitha kugwiritsidwa ntchito pama axles omwewo.Tsinde lalitali la axle limakupatsani mwayi wosintha mayendedwe a thirakitala mkati mwa malire akulu, ndipo tsinde lalifupi la axle limakupatsani mwayi wosintha chiŵerengero chomaliza chagalimoto ndi mawonekedwe oyendetsa thirakitala.

Tikumbukenso kuti ting'onoting'ono shaft zitsanzo ntchito pa zitsanzo akale ndi atsopano a mathirakitala MTZ (Belarus), iwo anaikidwa mu thirakitala ofanana UMZ-6.

Ma axle shafts amapangidwa ndi zitsulo zopangidwa ndi alloyed grade 20HN3A ndi ma analogue ake popanga mipiringidzo yowoneka bwino kapena kupangira moto.

 

Ma axle a MTZ a kumbuyo kwa chitsulo cham'mbuyo

Ma axle shafts amatenga malo kumbuyo kwa thirakitala, kulumikiza molunjika ku giya yomaliza yoyendetsedwa ndi ma gudumu.M'mathirakitala akale, shaft yowonjezera imalumikizidwa ndi njira yotsekera yosiyana.

Gawoli liri ndi mapangidwe osavuta: ndizitsulo zachitsulo zosinthika, mkati mwake zomwe zimagwirizana ndi chimodzi kapena ziwiri za spline, ndipo kunja kwake kuli mpando wokhazikitsa gudumu.Mpandowo umakhala ndi mainchesi osalekeza kutalika konse, mbali imodzi uli ndi poyambira pa kiyi ya hub, ndipo mbali inayi pali choyikapo mano cha nyongolotsi yosinthira mphutsi.Kapangidwe kameneka kamalola osati kukonza kachipangizo kachipangizo kakang'ono, komanso kusintha kosasintha kwa njanji m'lifupi mwake mawilo akumbuyo.Pakatikati pa tsinde la chitsulo pali phokoso loponyera ndi mpando wonyamulira, momwe gawolo limakhala lapakati ndikugwiridwa mu manja a shaft ya axle.

Pakadali pano, mitundu itatu ya ma axle shafts akumbuyo imagwiritsidwa ntchito, mawonekedwe awo akuwonetsedwa patebulo:

	Axle shaft cat.nambala 50-2407082-A ya zitsanzo zakale	Axle shaft cat.nambala 50-2407082-A1 ya zitsanzo zakale	Axle shaft cat.number 50-2407082-A-01 ya zitsanzo zatsopano
Utali	975 mm		930 mm
The awiri a shank pansi likulu	75 mm pa
The awiri a shank kuti atsike mu giya zoyendetsedwa ya galimoto yomaliza	95 mm pa
Chiwerengero cha ma shank splines otera mu giya yomaliza yoyendetsedwa, Z	20
Diameter shank ya loko yosiyana ndi makina	68 mm pa		Shanki yasowa
Chiwerengero cha ma shank splines a makina osiyana siyana, Z	14

 

Ndizosavuta kuwona kuti ma axle shafts akale ndi atsopano amasiyana mwatsatanetsatane - shank ya njira yotsekera yosiyana.Muzitsulo zakale za axle shank ili, kotero mu dzina lawo pali chiwerengero cha mano a ziboda zonse ziwiri - Z = 14/20.Muzitsulo zatsopano za axle shank ilibenso, kotero chiwerengero cha mano chimadziwika kuti Z = 20. Mitsuko yamtundu wakale ingagwiritsidwe ntchito pa thirakitala ya zitsanzo zoyambirira - MTZ-50/52, 80/82 ndi 100. /102.Magawo a chitsanzo chatsopano amagwiritsidwa ntchito pa mathirakitala a zosintha zakale ndi zatsopano za MTZ ("Belarus").Komabe, nthawi zina, ndizovomerezeka kuzisintha popanda kutaya magwiridwe antchito ndi mawonekedwe a kufala.

Ma axle shafts akumbuyo amapangidwa ndi zitsulo zomangidwa ndi alloy 40X, 35KHGSA ndi ma analogue awo popanga makina kapena kuwotcha.

 

Momwe mungasankhire molondola ndikusintha shaft yomaliza ya MTZ

Mitsempha yakutsogolo ndi yakumbuyo ya thirakitala ya MTZ imakhala ndi zolemetsa zazikulu, komanso kugwedezeka ndi kuvala kwa splines ndi mano a gear.Ndipo ma axle am'mbuyo amathanso kupindika, chifukwa amanyamula kulemera konse kumbuyo kwa thirakitala.Zonsezi zimayambitsa kuvala ndi kusweka kwa ma axle shafts, zomwe zimasokoneza magwiridwe antchito a makina onse.

Mavuto omwe amapezeka kwambiri pamapiko akutsogolo a axle ndi kuvala ndikuwonongeka kwa mano a bevel gear, kuvala kwa mpando wonyamulira mpaka m'mimba mwake osakwana 34.9 mm, ming'alu kapena kusweka kwa tsinde.Zowonongeka izi zimawonetseredwa ndi phokoso lapadera la PWM, maonekedwe a zitsulo zachitsulo mu mafuta, ndipo nthawi zina - kupanikizana kwa mawilo akutsogolo, ndi zina zotero. , komanso kuchotsa ma bere ku chitsulo chachitsulo.

Zovuta zodziwika bwino za ma axle shafts akumbuyo ndikuwonongeka kwa kagawo, kuvala kotsekera kotsekera kwa kiyi ya hub ndi njanji yosinthira nyongolotsi, komanso kupunduka kosiyanasiyana ndi ming'alu.Zowonongeka izi zimawonetseredwa ndi mawonekedwe a gudumu, kulephera kukhazikitsa odalirika kwa hub ndi kusintha kwa njanji, komanso kugwedezeka kwa magudumu pomwe thirakitala ikuyenda.Kuti muzindikire ndi kukonza, ndikofunikira kumasula gudumu ndi kabati ya hub, komanso kukanikiza tsinde la chitsulo pogwiritsa ntchito chokoka.Ntchito iyenera kuchitidwa motsatira malangizo a kukonza thirakitala.

Kuti mulowe m'malo, muyenera kusankha mitundu ya ma axle shafts omwe amalimbikitsidwa ndi wopanga thalakitala, koma ndizovomerezeka kukhazikitsa magawo a manambala ena amndandanda.Mipingo ya chitsulocho imatha kusinthidwa imodzi panthawi, koma nthawi zina zimakhala zomveka kuwasintha ndi awiri nthawi imodzi, chifukwa kutha kwa mano ndi mipando yonyamula pazitsulo zonse ziwiri zimachitika ndi mphamvu yofanana.Pogula shaft ya axle, mayendedwe angafunikire kusinthidwa ndipo magawo atsopano osindikizira (ma cuffs) ayenera kugwiritsidwa ntchito.Mukasintha shaft yakumbuyo, tikulimbikitsidwa kugwiritsa ntchito pini yatsopano ya cotter ndipo, ngati kuli kofunikira, nyongolotsi - izi zidzakulitsa moyo wa gawolo.

Ndi kusankha kolondola ndikusintha tsinde lomaliza la MTZ, thirakitala idzagwira ntchito modalirika komanso moyenera muzochitika zilizonse.
