7. Mafuta osindikizira a Crankshaft amatuluka

Makina atsopano nthawi zambiri amakhala ndi zifukwa zotsatirazi:

1. Malo otsegulira mphete ya pisitoni samasonkhanitsidwa molingana ndi zofunikira, kutayikira kwa mphete ya piston ndizovuta kwambiri, cylindricity ya cylindricity yatuluka, dzenje lalikulu la shaft ndi cylinder liner hole perpendicularity yatuluka ndipo piston. Kutsegula kwa mphete kumapita mbali imodzi chifukwa cha zifukwa zosiyanasiyana, izi zimapangitsa kuti kuthamanga kwa crankcase kuchepe, ndikupangitsa mafuta osindikizira a crankshaft mafuta osindikizira. Njira yothetsera vutoli ndikusintha magawo osayenerera malinga ndi zovuta zenizeni ndikuzisonkhanitsa molingana ndi zofunikira.

2. Crankshaft 50_8.os mm makulidwe a magazini ndi akulu, amatha kupukutidwa kuti athetse.

3. Crankshaft oil seal assembly skew, nthawi ino iyenera kulumikizidwanso chisindikizo chamafuta,

Kuchepetsa; Nthawi zina kuphatikiza kwa chisindikizo chamafuta kumakhala mkati kwambiri, ndipo kutayikira kwamafuta osindikizira a crankshaft kumachitika chifukwa chotsekereza gawo lina la bowo lobwereranso pachivundikiro chachikulu cha shaft. Chifukwa chake, pakusonkhanitsa, chosindikizira chamafuta a crankshaft chiyeneranso kuwululidwa kumapeto kwa chivundikiro cha spindle 1.5 ~ 2 mm.

4 mafuta osindikizira mafuta a crankshaft ndi osauka, milomo si yosalala, osati yofewa, iyenera kusinthidwa ndi chisindikizo chamafuta abwino. Ngati kasupe wosindikizira mafuta akusowa kapena chitsanzocho ndi cholakwika, kasupe ayenera kusinthidwa panthawi yake kapena chisindikizo chatsopano cha mafuta amtundu womwewo chiyenera kusinthidwa.

5. Mukasonkhanitsa chisindikizo chamafuta, mlomo wa chisindikizo chamafuta amakandwa ndi kutsogolo kwa kiyi ya flywheel pa crankshaft, zomwe zingayambitsenso kutayikira kwa chisindikizo chamafuta. Chifukwa chake, mukamayika chisindikizo chamafuta, mutha kutembenuza kanjira kanjira ka crankshaft flywheel kupita kumtunda, kukwapula kutsogolo kwa njirayo ndi tsamba lakale la macheka, ndikukweza chisindikizo chamafuta ndi dzanja pamene chisindikizo chamafuta a crankshaft. imayikidwa mkati, kuti musamakanda mlomo wa chisindikizo cha mafuta.

6. Musanasonkhanitse chisindikizo cha mafuta, crank shaft monga 50-8.o. Mafuta pa mm magazine amathanso kuyambitsa kutayikira kwa mafuta a crankshaft. Choncho, tisanasonkhanitse chisindikizo cha mafuta a crankshaft, tiyenera kuonetsetsa kuti ndalama za crankshaft 50-8.os mm magazini ndi zoyera komanso zopanda mafuta.
