I. Ihe achọrọ maka ọrụ na ojiji nkeIhe ndị e ji arụ ọrụ crankshaft

Ihe ndị e ji arụ ọrụ na crankshaft gụnyere njikọ mkpanaka na ihe ndị e ji arụ ọrụ na isi. Ọrụ ha bụ ichebe akwụkwọ ndekọ na ihe ndị e ji arụ ọrụ na-ebelata esemokwu na mmebi. Ha na-agbanwe ike gas nke sitere na mgbakọ mkpanaka nke piston ka ọ bụrụ torque maka mmepụta mpụga. A na-ejikwa ha akwọ ụgbọ okporo ígwè valvụ injin na ngwaọrụ enyemaka dị iche iche.

 

Ihe achọrọ maka ojiji: Ha niile na-eguzogide ibu ndị na-agbanwe agbanwe na esemokwu ọsọ ọsọ; ya mere, ihe ndị na-ebu ibu ga-enwerịrị ike ọgwụgwụ zuru oke, obere esemokwu, ike iyi, na iguzogide nchara.

 

II. Nhazi nkeIhe ndị e ji arụ ọrụ crankshaft

 

Ma bearing mkpanaka ndị jikọtara ọnụ na bearing ndị bụ isi nwere shells elu na ala jikọtara ọnụ. Ihe mejupụtara shelf bearing ọ bụla bụ azụ ígwè na oyi akwa alloy na-egbochi esemokwu, ma ọ bụ azụ ígwè, oyi akwa alloy na-egbochi esemokwu, na oyi akwa dị nro. A na-akpọ nke mbụ shelf bearing nke nwere oyi akwa abụọ, a na-akpọkwa nke ikpeazụ shelf bearing nke nwere oyi akwa atọ.

 

1. Akwado ígwè na oyi akwa mgbochi esemokwu

Ihe nkwado ígwè ahụ bụ ihe e ji emechi ihe mkpuchi ahụ, nke e ji ígwè dị obere carbon nke dị 1-3mm mee. Ihe mkpuchi mgbochi mgbakasị ahụ bụ ihe mkpuchi mgbochi mgbakasị ahụ nke dị 0.3 ~ 0.7mm, nke dị nro ma nwee ike ichebe akwụkwọ ndekọ ahụ.

 

Ihe mkpuchi oyi akwa mgbochi esemokwu:

 

(1) Alloy ọcha (Babbitt alloy): Ọ na-arụ ọrụ nke ọma megide esemokwu, mana ọ dị obere ike igwe na enweghị ike iguzogide okpomọkụ. A na-ejikarị ya eme ihe na injin mmanụ ụgbọala nwere obere ibu.

 

(2) Ihe e ji ọla kọpa mee: Ike igwe dị elu, ikike ibu ibu dị elu, na ezigbo iguzogide okpomọkụ. A na-ejikarị ya eme ihe na injin dizel dị elu. Agbanyeghị, arụmọrụ ya na-egbochi esemokwu adịghị mma.

 

(3) Aluminom nke e ji ígwè rụọ: E nwere ụdị atọ: aluminum-antimony-magnesium alloy, aluminum-lin-tin alloy, na aluminum-tin-high-tin alloy. Abụọ mbụ nwere ezigbo ihe eji arụ ọrụ na ikike ibu ibu siri ike, mana arụmọrụ mgbochi esemokwu adịghị mma. A na-ejikarị ya eme ihe na injin dizel; nke ikpeazụ nwere ezigbo ihe eji arụ ọrụ na arụmọrụ mgbochi esemokwu, a na-ejikwa ya nke ukwuu na injin dizel na petrol.

 

2. Igodo na oghere mmanụ

 

Ebe a na-etinye ihe e ji ejikọta ihe nwere igodo ebe a na-etinye ihe, nke a na-eji etinye ya n'ime oghere ebe a na-etinye ihe e ji ejikọta ihe na okpu ebe a na-ejikọ ihe n'oge a na-etinye ihe iji gbochie ebe a na-etinye ihe n'ime ihe ahụ ka ọ ghara ịgagharị ma ọ bụ tụgharịa. Osisi ebe a na-etinye ihe nwekwara oghere mmanụ na oghere mmanụ, nke kwesịrị ịdị n'otu na oghere mmanụ ndị kwekọrọ n'oge a na-etinye ihe.

1. Ike Nnwere Onwe: radius nke mgbagọ nke osisi na-ebu ibu n'ọnọdụ nnwere onwe ya buru ibu karịa radius nke oche na-ebu ibu. A na-akpọ ọdịiche dị na dayameta ike nnwere onwe ma ọ bụ oghere. Maka injin mmanụ ụgbọala, ọ na-abụkarị 0.8 ~ 1.5mm, maka injin dizel, ọ bụ 1.5 ~ 2.5mm.

 

2. Ndozi Ndozi: Ebe ọ bụ na okirikiri mpụta nke osisi na-ebu ibu buru ibu karịa gburugburu nke oche na-ebu ibu, a na-emepụta njikọ nnyonye anya ụfọdụ mgbe ejiri bolts mkpanaka jikọtara ya sie ike. Nke a na-eme ka osisi na-ebu ibu ghara ịtụgharị, gbanwee, ma ọ bụ maa jijiji n'oge ọrụ, nke na-enye ohere ka e nwee njikọ siri ike n'etiti osisi na-ebu ibu na oche na-ebu ibu iji mee ka okpomọkụ dị mfe. Oke mkpuchi nke osisi na-ebu ibu na-abụkarị 0.04 ~ 0.09mm.

 

Nnyocha: Mgbe etinyere bearing ahụ n'oche bearing ahụ, sie ike bolts n'akụkụ abụọ ahụ ruo na torque nke onye nrụpụta ahụ kwuru. Mgbe ahụ, tọpụ bolts ahụ kpamkpam n'otu akụkụ wee jiri ihe nlele iji lelee oghere dị n'etiti oche bearing na bearing ahụ. Nha a bụ bearing overhang. IV. Crankshaft Thrust Bearing

 

Ọrụ nke Crankshaft Thrust Bearing: Mgbe ụgbọala na-agagharị, pedal clutch na-etinye nrụgide axial na crankshaft, na-eme ka mmegharị axial. Mmegharị axial gabiga ókè ga-emetụta ọrụ nkịtị nke njikọ mkpanaka piston ma mebie oge valvụ kwesịrị ekwesị na oge ntinye injin dizel. A chọrọ bearings thrust iji hụ na crankshaft ahụ dị n'ọnọdụ axial.

 

Enwere ike itinye bearings thrust naanị n'otu ebe iji hụ na crankshaft nwere ike ịgbasa n'enweghị nsogbu mgbe a na-ekpo ọkụ. Ụdị ndị bụ isi gụnyere:

 

1. Shei ebu nke nwere flanged

 

2. Ihe e ji amịpụta ihe ndị e ji amịpụta ihe n'ime ọkara okirikiri

 

3. Ihe eji asa ákwà okirikiri

 

Ihe Ndị A Ga-akpachara Anya Banyere Ntinye: Akụkụ nke igwe e ji ebugharị ihe nwere oyi akwa mgbochi esemokwu (akụkụ ya na oghere mmanụ) na-eche akụkụ ndị na-agbagharị agbagharị ihu. Mgbe igwe e ji crankshaft gaa n'ihu, igwe e ji ebugharị ihe n'azụ na-ebu ebugharị axial; mgbe ọ na-aga azụ, igwe e ji ebugharị ihe n'ihu na-ebu ebugharị axial.

 

Mgbanwe nke Axial Clearance: Jiri igwe washers nke nwere ọkpụrụkpụ dị iche iche dochie ya, ma ọ bụ gbanwee ọkpụrụkpụ nke igwe washers. (Ọkwa ọkọlọtọ na-abụkarị 0.07 ~ 0.17mm, yana oke a na-anabata nke 0.25mm).

 

V. Ụzọ Nkwado Crankshaft

A na-akpọ crankshaft nwere akwụkwọ ndekọ dị mkpa n'etiti crankshaft abụọ ọ bụla dị nso crankshaft nke a na-akwado nke ọma; ma ọ bụghị ya, a na-akpọ ya crankshaft nke a na-akwado nke ọma.

 

1. Crankshaft akwadoro nke ọma:

 

Uru: Na-eme ka ike crankshaft na ike ịgbagọ dịkwuo elu; na-ebelata ibu dị na bearings bụ isi.

 

Ihe Ọjọọ: Ọ na-eme ka ọnụọgụ elu igwe dị na crankshaft dịkwuo elu, na-eme ka ọnụọgụgụ bearings bụ isi dịkwuo elu, ma na-eme ka blọk injin ahụ dịkwuo ogologo.

 

Ngwa: A na-eji ya eme ihe nke ukwuu; injin dizel na-ejikarị usoro nkwado a eme ihe.

 

2. Crankshaft akwadoro nke ọma:

 

Uru: Na-eme ka ogologo crankshaft dị mkpụmkpụ, na-ebelata ogologo injin ahụ dum.

 

Ihe ọghọm: Ọ chọrọ ibu dị elu na bearings bụ isi.

 

Ngwa: Injin mmanụ ụgbọala nwere obere ihe achọrọ maka ibu nwere ike iji usoro a.
