Yintoni ukuthwala?
Iibheringi ngamalungu axhasa i-shaft, esetyenziselwa ukukhokela ukunyakaza okujikelezayo kwe-shaft, kunye nokuthwala umthwalo ohanjiswe ukusuka kwi-shaft ukuya kwisakhelo. Iibheringi zisetyenziswa ngokubanzi kwaye zifuna iinxalenye ezixhasayo kunye neenxalenye ezisisiseko kwishishini loomatshini. Zingamacandelo axhasayo eeshafu ezijikelezayo okanye iindawo ezishukumayo zoomatshini abahlukeneyo, kwaye zingamacandelo axhasayo axhomekeke ekuqengqelekeni kwemizimba eqengqelekayo ukuqonda ukujikeleza kwenjini engundoqo. Eyaziwa ngokuba ngamalungu omatshini.
Kufuneka zihlelwe njani iibheringi?
Ngokweendlela ezahlukeneyo zokungqubana xa ijenali isebenza kwibheringi, iibheringi zohlulwe zibe ziindidi ezimbini:
iibheringi ezityibilikayo kunye neebheringi eziqengqelekayo.

Ukuthwala okucacileyo
Ngokolwalathiso lomthwalo ekuthwaleni, iibheringi ezityibilikayo zohlulwe zibe ziindidi ezintathu:①Ukuthwala iRadial——ukuthwala umthwalo weradial, kwaye umkhombandlela womthwalo uxhomekeke kumbindi weshaft;
②I-Thrust Bearing——ukuthwala umthwalo we-axial, kwaye ulwalathiso lomthwalo lungqamene nomgca osembindini weshafti;
③I-Radial-thrust bearing--ngaxeshanye ithwala imithwalo yeradial kunye ne-axial.
Ngokwemeko yokruthakruthwano, iibheringi ezityibilikayo zohlulwe zibe ziindidi ezimbini: iibheringi zokutyibilika ezingezizo zolwelo kunye neebheringi ezityibilikayo ezityibilikayo. Eyangaphambili ikwimeko yokukhuhlana okomileyo okanye ukukhuhlana komda, kwaye le yokugqibela ikwimeko yolwelo.
