Plaub hom kev puas tsuaj rau crankshafts
2020-01-02
Tom qab lub cav siv tau ntev, lub crankshaft yuav puas vim muaj ntau yam. Ntxiv rau lub crankshaft nws tus kheej, muaj lwm yam kev puas tsuaj, xws li khawb ntawm qhov chaw ntawm cov ntawv xov xwm thiab deformation ntawm lub crankshaft.
1.Qhov sib txawv ntawm crankshaft phau ntawv journal thiab bearing bush nce tom qab hnav
Thaum lub crankshaft tig, nyob rau hauv qhov kev txiav txim ntawm centrifugal quab yuam, cov neeg kho tshuab impurities nyob rau hauv cov roj yog inclined mus rau ib sab ntawm cov roj qhov thiab ua abrasive, uas ua rau cov phau ntawv journal hnav unevenly thiab ua taper.
2.Scratch lossis rub rau saum npoo ntawm crankshaft phau ntawv xov xwm
Lub lubricating roj ntawm cov roj twj tso kua mis tsis hloov raws sij hawm, yog li ntawd cov roj lubricating muaj cov hlau loj thiab lwm cov khoom abrasive sib xyaw rau hauv qhov sib txawv ntawm cov kabmob plhaub thiab cov ntawv xov xwm los cim thiab rhuav tshem qhov kev sib txhuam.
Kev saib xyuas huab cua tsis nyob hauv qhov chaw, lub tog raj kheej liner, piston thiab piston nplhaib hnav qhov sib txawv nce, nrog cov xuab zeb, impurities thiab lwm yam abrasives nrog cua nqus pa cylinder combustion tom qab khiav mus rau hauv cov roj sump, ncig mus rau hauv phau ntawv xov xwm thiab cov kabmob clearance.
3.Lub crankshaft deformation
Crankshaft deformation feem ntau yog khoov deformation thiab torsional deformation, ntau dhau deformation ntawm lub crankshaft yuav ua rau nws tus kheej thiab kev sib txuas ntawm qhov hnav, ua kom qaug zog, crankshaft puas thiab ntau yam kev co.
4.Crankshaft puas
Txhua yam ua rau crankshaft journal nto tawg thiab crankshaft dabtsi yog khoov thiab distortion yog ua rau crankshaft puas.
