Plaub qhov tseem ceeb cuam tshuam rau kev muaj peev xwm ntawm cov nplhaib slewing

Nws muaj ob hom ntawm lub kaum ntsej muag nplhaib kev puas tsuaj, ib qho yog qhov kev puas tsuaj rau haiv neeg, thiab ib qho yog qhov mob hniav. Cov kev sib tw ua kev puas tsuaj rau ntau dua li 98%, yog li cov kev sib tw muaj txiaj ntsig zoo yog qhov tseem ceeb cuam tshuam rau lub neej ntawmlub kaum ntsej muag nplhaibCov. Ntawm lawv, raceway hardness, hardened txheej qhov tob, haiv neeg curvature vojvoog thiab chaw sib cuag kaum yog plaub yam tseem ceeb tshaj plaws uas cuam tshuam rau kev ua kom zoo ntawm cov haiv neeg.

1. Kev sib tw tawv tawv

Lub quenching hardness ntawm lub lub kaum ntsej muag nplhaib raceway muaj qhov cuam tshuam loj dua rau nws cov rated zoo li qub load. Yog tias cov ntsuas cov nqi zoo li qub yog 1 ntawm 55HRC, txoj kev sib raug zoo nruab nrab ntawm cov rated zoo li qub load ntawm cov kabmob thiab qhov nyuaj ntawm txoj kev sib tw yog raws li hauv qab no :

 Tus slewing cov kabmob los ntawm Xuzhou Wanda slewing cov kabmob tuam txhab raceway hardness yog 55HRC ~ 62HRC.

 2.Kev nkag siab ntawm cov tawv tawv txheej kev sib tw

Qhov tsim nyog tob ntawm txheej hardened yog qhov lees tias tus lub kaum ntsej muag nplhaib raceway tsis spall. Thaum covslewing cov kabmob Dais rau sab nraud ntawm sab nraud, pob steel thiab haiv neeg hloov ntawm taw tes sib cuag mus rau saum npoo, thiab qhov chaw tiv tauj yog pob npoo npoo. Ntxiv nrog rau qhov kev ntxhov siab compressive, txoj kev sib tw yeej tseem muaj kev ntxhov siab shear, thiab qhov siab tshaj plaws ntawm kev txiav txim siab tshwm sim ntawm qhov tob ntawm 0.47a (qhov loj ib nrab ntawm qhov sib tiv tauj ellipse) hauv qab ntawm qhov chaw, Qhov no kuj yog vim li cas vim li cas hardened txheej qhov tob tau teev nyob hauv tus qauv raws li txoj kab uas hla ntawm lub pob steel tsis hloov ntawm txoj kab uas hla ntawmlub kaum ntsej muag nplhaib, thiab qhov tsawg kawg nkaus lav tus nqi yog muab nyob rau hauv tus qauv. Cov ntsuas cov nqi zoo li qub C ntawm cov kabmob yog sib npaug rau ntawm qhov tob ntawm cov txheej txheej tawv tawv H0.908. Yog tias cov txheej txheej tawv tawv yuav tsum muaj 4 hli tsuas yog quenched rau 2.5 hli, cov kabmob zoo li qub load C yuav txo ntawm 1 mus rau 0.65, qhov tshwm sim ntawm kev puas tsuaj rauslewing cov kabmob vim ua rau qaug zog cov tev yuav loj heev.

Piv txwv li, tus slewing cov kabmob haiv neeg txheej txheej tob013.35.1250 haiv neeg sib tw yog is 3.5 hli.

 

 3.Cov vojvoog luv ntawm txoj kev sib tw

Kev sib tw khiav ntawm lub voj voos kev sib tw yog hais txog qhov vojvoog ntawm lub voj voog ntawm txoj kev sib tw hauv feem ntsug. Qhov piv t ntawm lub vojvoog ntawm txoj kev sib tw mus rau lub vojvoog ntawm lub pob steel kuj tseem cuam tshuam cov rated zoo li qub load thiab lub neej qaug zog ntawm covlub kaum ntsej muag nplhaibCov. Thaum t = 1.04, cov rated zoo li qub load thiab lub neej qaug zog yog 1, thiab qhov sib txuam ntawm cov rated zoo li qub load thiab lub neej qaug zog ntawm covlub kaum ntsej muag nplhaib thiab t yog raws li nram no.

Curvature piv 1,04 1,06 1,08 1.10
Nyob zoo li qub load 1 0.82 0.72 0.65
Qaug zog lub neej 1 0,59 0.43 0.33

 Nws tuaj yeem pom los ntawm cov lus saum toj no tias qhov loj dua ntawm cov hluav taws xob sib piv, qis dua cov rated zoo li qub load thiab luv dua kev pab cuam lub neej.

 4.Txoj kev sib cuag kaum

Lub kaum sib tiv tauj yog hais txog lub kaum sab xis ntawm txoj kab sib txuas ntawm qhov kis rau ntawm lub pob steel ntawm txoj kev sib tw thiab qhov chaw nruab nrab ntawm lub npov steel thiab ntu radial (dav hlau tav toj) ntawm slewing cov kabmobCov. Cov rated zoo li qub load C ntawmlub kaum ntsej muag nplhaib yog linearly proportional rau SINα, thiab lub kaum kev tiv tauj lub thawj yog feem ntau 45 °. Thaum covslewing cov kabmob muaj qhov sib txawv, lub kaum sib tiv tauj tiag tiag yog ntau dua li lub kaum ntsees ntawm kev sib tiv tauj ib txwm. Qhov loj dua qhov sib txawv, qhov loj dua qhov tseeb lub kaum sab xis. Tsis pub dhau qhov sib txawv ntawm cov qauv teev tseg, nws feem ntau yuav nce li 2 ° ~ 10 °, uas yog, lub sijhawm tiv tauj qhov tseeb yuav ncav cuag 47 ° ~ 55 °, uas yog qhov kev hloov pauv zoo rau lub peev xwm nqa tau. Tab sis yog tias qhov sib tiv tauj lub kaum ntse ntse thiab qhov sib txawv yog qhov loj, lub sijhawm tiv tauj tiag tiag yuav dhau 60 °. Raws li qhov kev tso tawm ntawm lub cev tso tawm, qhov sib txawv yuav txuas ntxiv thiab qhov tseeb hu rau lub kaum ntse ntse yuav tseem nce. Nyob rau lub sijhawm no, lub xov tooj hu tau mus yuav dhau qhov puas ntawm qhov kev sib tw. , Lub zog tiag tiag ntawm txoj kev sib tw yuav siab dua qhov theoretical suav kev ntxhov siab, uas yuav ua rau cov ntug kev sib tw tawg thiabslewing cov kabmob yuav swb.

Piv txwv li, lub yeej tiv tauj kaum sab xis ntawm lub slewing cov kabmob 013.40.1250 yog 45 °.

 

Ua tsaug rau kev saib cov kab lus no, yog tias koj muaj lus nug dab tsi ntawm ntiv nplhaib ntiv tes kabmob, tsuas yog xav tiv tauj peb!
