Izinhlobo ezine zomonakalo kuma-crankshafts
2020-01-02
Ngemuva kokuthi injini isetshenziswe isikhathi eside, i-crankshaft ingalimala ngenxa yezizathu eziningi. Ngaphezu kwe-crankshaft ngokwayo, kukhona omunye umonakalo ongavamile, njengokuklwebheka ebusweni bejenali kanye nokuguqulwa kwe-crankshaft.
1.Igebe phakathi kwejenali ye-crankshaft ne-bearing bush liyakhula ngemva kokugqoka
Lapho i-crankshaft izungeza, ngaphansi kwesenzo samandla amaphakathi, ukungcola okusemishinini kawoyela kuthambekela ohlangothini olulodwa lwembobo kawoyela bese kuba nokuhuga, okubangela ukuthi iphephabhuku liguge ngendlela engalingani futhi likhiqize i-taper.
2.Khwaya noma donsa phezu kwejenali ye-crankshaft
Uwoyela wokugcoba we-sump kawoyela awushintshiwe ngesikhathi, ukuze uwoyela wokugcoba uqukethe insimbi enkulu nezinye izinhlayiya ezilumayo ezixutshwe esikhaleni segobolondo elithwele kanye nejenali ukuze kuphawulwe futhi kudabuke indawo yokungqubuzana.
Ukugcinwa kwesihlungi somoya akukho endaweni, i-cylinder liner, i-piston ne-piston ring igebe yokugqoka iyakhuphuka, ngesihlabathi, ukungcola nezinye iziqhumane ezinokusha kwesilinda sokuphefumula komoya ngemva kokugijima ku-sump kawoyela, ukuzungeza kujenali kanye nokukhipha imvume.
3.I-crankshaft deformation
I-Crankshaft deformation ivamise ukugoba i-deformation kanye ne-torsional deformation, ukuwohloka okuningi kwe-crankshaft kuzoholela ezingxenyeni zayo zokuguga nezixhumene, ukukhathala okusheshayo, ukuphuka kwe-crankshaft kanye nokudlidliza kwemishini ngokweqile.
4.Ukuphuka kukaCrankshaft
Zonke izimbangela zejenali ye-crankshaft surface crack kanye nokugoba nokuhlanekezela kwe-crankshaft yizimbangela zokuphuka kwe-crankshaft.
