MTZ axle shaft na karshe drive: mai karfi mahada a cikin watsa na tarakta

An gina watsawar kayan aikin MTZ bisa ga tsarin gargajiya - karfin jujjuyawar injin ta hanyar kama da akwatin gear yana shiga cikin gatari na baya, inda aka fara canza shi ta babban kayan aiki, ya wuce ta hanyar bambance-bambancen ƙirar da aka saba, kuma ta hanyar kayan aiki na ƙarshe ya shiga ƙafafun motar.Gears ɗin tuƙi na ƙarshe suna da alaƙa kai tsaye zuwa raƙuman axle waɗanda ke wuce gidan watsawa kuma suna ɗaukar cibiyoyi.Saboda haka, ramukan axle na MTZ suna yin ayyuka biyu a lokaci ɗaya:

• Isar da juzu'i daga kayan aiki na ƙarshe zuwa dabaran;
• Ƙarƙashin ƙafar ƙafa - riƙewa da gyarawa a cikin jiragen sama guda biyu (ana rarraba kaya tsakanin shingen axle da casing).

A kan gyare-gyaren gyare-gyare na MTZ tarakta, ana amfani da PWMs na ƙirar da ba daidai ba.Ƙarfin wutar lantarki daga akwatin gear ta hanyar yanayin canja wuri ya shiga cikin babban kayan aiki da bambanci, kuma daga gare ta ana watsa shi ta hanyar ma'auni na axle zuwa maƙallan tsaye da motar motar.Anan, shingen axle ba shi da alaƙa kai tsaye tare da ƙafafun tuƙi, don haka ana amfani da shi kawai don watsa juzu'i.

MTZ axle shafts suna taka muhimmiyar rawa wajen aiki na yau da kullun na watsawa, don haka duk wata matsala da waɗannan sassan ke haifar da rikitarwa ko cikakkiyar rashin yiwuwar aiki da tarakta.Kafin maye gurbin ginshiƙan axle, ya zama dole don fahimtar nau'ikan su, ƙira da halaye.

 

Nau'i, ƙira da halaye na MTZ na ƙarshen tuƙi axle shafts

Duk MTZ axle shafts sun kasu kashi biyu bisa ga manufarsu:

• Wuraren axle na gaba (PWM), ko kuma kawai madaidaicin axle na gaba;
• Wuraren axle na tuƙi na ƙarshe na axle na baya, ko kuma kawai raƙuman axle na baya.

Har ila yau, cikakkun bayanai sun kasu kashi biyu na asali:

• Asali - wanda RUE MTZ ya samar (Minsk Tractor Plant);
• Ba na asali - samar da Ukrainian Enterprises TARA da RZTZ (PJSC "Romny Shuka" Traktorozapchast "").

Bi da bi, kowane daga cikin nau'in axle shafts yana da nasa iri da halaye.
