Iibheringi zesitimela - iimpawu kunye nezicelo zeebheringi zebhokisi yegiya ye-axle

Ngokuphuhla koluntu, ishishini lokuvelisa oomatshini boololiwe liyaqhubeka nokuphucuka, xa kuthelekiswa netekhnoloji yokuvelisa iibheringi zoololiwe nayo iphucuka rhoqo, apho indima ephambili yebheringi eqengqelekayo kwibhokisi yeegiya kukukwazi ukuhambisa i-torque yokukhupha ngokuzinzileyo xa ilocomotive isebenza ngesantya esiphezulu, oko kuthetha ukuba kufuneka ithwale umthwalo wempembelelo oguqukayo kwindawo enzima. Iintlobo eziphambili zeebheringi ziibheringi ezirhuqwayo, iibheringi zoqhagamshelwano ezine-point ezine kunye neebheringi ezirhuqwayo ze-cylindrical. Amalungiselelo ebheringi ayahluka ngokuxhomekeke kuyilo kunye neemeko zokusebenza kwebhokisi yeegiya.

 

Iibheringi zebhokisi yegiya ye-axle

Eyona ndlela iphambili yokusebenza kweebheringi zeebhokisi zegiya yile:

Isantya esiphezulu; Ithwala umthwalo ophezulu; Ukungcangcazela kunye nokumelana nomothuko; Ukumelana nobushushu obuphezulu.

Ukukhethwa kwebhereyitha kugqitywa ngokobungakanani bendawo efanelekileyo yebhokisi yegiya, kuthathelwa ingqalelo izinto ezisetyenzisiweyo ezingasentla, kwaye ngokubanzi kufuna ubomi obubalwe ngaphezulu kwe-2 yezigidi zeekhilomitha.

 

Izicelo zeebheyari zebhokisi yegiya ye-axle

1. Iibheringi zerola ezithambileyo

Iibheringi zerola ezigobileyo ziyahlukaniswa, kwaye indibano yazo yangaphakathi yerola yekheyiji kunye neringi yangaphandle zinokuhlanganiswa ngokwahlukeneyo. Unxibelelwano oluchanekileyo oluphakathi kwezinto ezigobileyo kunye nendlela yokugijima luthintela uxinzelelo lomphetho. Iibheringi zerola ezigobileyo zinokumelana nemithwalo ephezulu yeradial kunye ne-axial. Ngenxa yokuba ezi bearing zinokumelana namandla e-axial kuphela kwicala elinye, kufuneka zisetyenziswe kwizicelo zokubhangqa. Olu hlobo lwebheringi lusetyenziswa kwiibhokisi zegiya kunye neebhokisi ze-axle.

 

2. Ukuthwala koqhagamshelwano oluneendawo ezine

Iibheringi zebhola zoqhagamshelwano ezine-point ezine ziibheringi zebhola zoqhagamshelwano ezine-angular. Zinokumelana nemithwalo ye-axial kuzo zombini iindlela kwaye zihlala zidibene neebheringi ze-cylindrical roller ukuze zimelane namandla e-radial, kunye nokulingana kwe-radial clearance. Ulwakhiwo oluqhekekileyo lwendandatho yangaphakathi luyivumela ukuba ihlanganise iibhola zentsimbi ezingaphezulu. Ezi bearing zisetyenziswa kwiibhokisi zegiya.

 

3.Iibheringi zerola ezisilinda

Iibheringi zeroli ezisilinda-silinda ezikwimigca enye zisetyenziswa kakhulu kwiibheringi zikaloliwe kunezinye iibheringi kuba iringi yangaphakathi inokwahlulwa kwindibano eyenziwe yiringi yangaphandle, iiroli kunye nekheji, nto leyo eluncedo kakhulu ekufakweni, ekuqhawuleni, ekugcinweni nasekuhlolweni kwebheringi. Iibheringi zeroli ezisilinda ziyakwazi ukumelana namandla aphezulu e-radial, kwaye unxibelelwano oluchanekileyo oluphakathi kwezinto eziqengqelekayo kunye nendlela yokugijima lususa uxinzelelo lomphetho, nto leyo enyusa ukuthembeka kwezicelo zeebheringi. Ukudibana kweebheringi zeroli ezisilinda ze-NJ kunye ne-NUP kunokumelana namandla angapheliyo e-axial. Ezi bearing zisetyenziswa kwiimoto zokudonsa, iibhokisi zegiya, kunye nee-wheelset hollow shaft drives.

 

4. Iibheringi ezigqunyiweyo

Phantsi kweemeko ezithile zokusebenza ezimbi okanye ezikhethekileyo, i-shaft bearing kunye ne-motor bearing zinokonakala ngenxa ye-voltage eyongezelelweyo. Nangona inkqubo yokuvelisa i-motor igqibelele, akunakwenzeka ukuba uphephe ngokupheleleyo umahluko onokubakho phakathi kwe-rotor kunye ne-stator ngenxa ye-electromagnetic asymmetry, ngoko ke i-current idlula kwi-bearing kwaye yenze i-closed circuit. Ukuze uphephe le meko ingentla, faka i-oxide ceramic coating kumphezulu weringi yangaphandle ye-bearing ukuvimba i-voltage engaphantsi kwe-1000V, kwaye ukhusele i-bearing ekungaphumeleli kwe-bearing ngenxa yokukhukuliseka kombane okubangelwa yi-voltage eyongezelelweyo.
