Kutheni i-crankshaft yokugcina ebandayo yophuka?

Ukwaphuka kweCrankshaft

Uninzi lwamaqhekeza lwenzeka kutshintsho phakathi kwejenali kunye nengalo yekrank. Izizathu zezi zilandelayo: i-radius yenguqu incinci kakhulu; i-radius ayicutshungulwa ngexesha lokunyanga ukushisa, okubangela ukuxinzezeleka koxinzelelo kwi-junction; iradiyasi icutshungulwa ngokungaqhelekanga, kunye neenguqu zengingqi ezinqamlezayo; ixesha elide umsebenzi overload, kwaye abanye abasebenzisi ukwandisa isantya ngentando ukunyusa imveliso, nto leyo mbi imeko yoxinzelelo; impahla ngokwayo ineziphene, njengemingxuma yesanti kunye ne-shrinkage kwi-casting. Ukongeza, iintanda kumngxunya we-oyile kwi-crankshaft nazo zingabonwa zibangela ukuphuka.

Uhlalutyo lwesizathu sokusilela:

1. Umgangatho ophantsi we-crankshaft

Ukuba i-crankshaft ayiyoqobo kwaye ikumgangatho ophantsi, ukusebenza kwesantya esiphezulu se-excavator kunokubangela lula ukuba i-crankshaft iphuke.

2. Ukusebenza ngokungafanelekanga

Ngethuba lokusebenza kwe-excavator, ukuba i-throttle inkulu kakhulu / incinci kakhulu, iguquguqukayo, okanye i-excavator iqhutywe kumthwalo ophezulu ixesha elide, i-crankshaft iya konakaliswa ngamandla amaninzi kunye neempembelelo, ezibangela ukuphuka.

3. Ukuqhoboshwa rhoqo okungxamisekileyo

Xa usebenzisa i-excavator, ukuba i-clutch pedal ayinyathelwa rhoqo, i-braking engxamisekileyo iya kubangela ukuba i-crankshaft iphuke.

4. Iibheringi eziphambili azihambelani

Xa ufaka i-crankshaft, ukuba imigca yeziko leebheringi eziphambili kwibhloko ye-cylinder ayihambelani, emva kokuba i-excavator iqaliswe, kulula ukubangela ukuba iibheringi zitshise kwaye i-shaft ibambelele, ngaloo ndlela ibangela ukuba i-crankshaft iphule.

5. Ukuthanjiswa kwe-crankshaft kakubi
Ukuba impompo yeoli igugile kakhulu, unikezelo lweoyile alwanelanga, uxinzelelo lweoyile alwanelanga, kwaye umjelo we-oyile wokuthambisa i-injini uvaliwe, i-crankshaft kunye ne-bearing iya kuba kwimeko yokukhuhlana ixesha elide, okubangela ukuba i-crankshaft iphuke.

6. Umsantsa phakathi kwamalungu ecrankshaft mkhulu kakhulu

Ukuba umsantsa phakathi kwejenali yecrankshaft kunye nokuthwala mkhulu kakhulu, i-crankshaft iya kuba nefuthe kwi-bearing emva kokuba i-excavator iqhuba, ibangela ukuba i-bearing itshise kwaye i-crankshaft yonakaliswe.

7. I-flywheel ekhululekile

Ukuba iibholithi ze-flywheel zikhululekile, iinxalenye ze-crankshaft ziya kuphulukana nebhalansi yazo yangaphambili kwaye zishukume ngexesha lokusebenza kwe-excavator, enokubangela ngokulula ukuba umsila we-crankshaft uphuke.

8. Ukusebenza okungalungelelananga kwe-cylinder nganye

Ukuba i-cylinders enye okanye ngaphezulu ye-excavator ayisebenzi, iisilinda azilingani, kwaye ukuphambuka kobunzima beqela le-piston yokudibanisa intonga inkulu kakhulu, kuya kubangela ukuba i-crankshaft iphuke ngenxa yamandla angalingani.

9. Ixesha lokubonelela nge-oyile kwangoko

Ukuba ixesha lonikezelo lwamafutha lingaphambili kakhulu, idizili iya kutshisa ngaphambi kokuba ipiston ifike kwindawo efileyo, okuya kubangela ukuba i-crankshaft ibe phantsi kwempembelelo enkulu kunye nomthwalo. Ukuba umsebenzi wenziwa ngolu hlobo ixesha elide, i-crankshaft iya kudinwa kwaye yaphuke.

10. Ipiston yaphukile kwaye inyanzelekile ukuba isebenze

Ukuba ukuphuma kwamandla kuncitshisiwe kwaye kukho isandi esingaqhelekanga kwi-cylinder, qhubeka usebenza. Kusenokwenzeka ukuba ipiston yaphukile, nto leyo ebangela ukuba i-crankshaft ilahlekelwe yibhalansi, ikhubazeke okanye iphuke lula.
