Lub tswv yim ntawm lub zog yog kev ua haujlwm ua ib lub sijhawm.Nyob rau hauv cov xwm txheej ntawm ib lub hwj chim, qhov siab dua qhov ceev, qhov qis dua lub zog torque, thiab vice versa.Piv txwv li, tib lub 1.5kw lub cev muaj zog, qhov tso zis torque ntawm theem 6 yog siab dua li ntawm theem 4.Cov mis M = 9550P / n kuj tuaj yeem siv rau kev suav ntxhib.
Rau AC motors: ntsuas torque = 9550 * rated zog / ntsuas ceev;rau DC motors, nws muaj teeb meem ntau dua vim tias muaj ntau hom.Tej zaum qhov kev sib hloov ceev yog proportional rau armature voltage thiab inversely proportional rau excitation voltage.Torque yog proportional rau lub teb flux thiab armature tam sim no.
- Kho lub armature voltage nyob rau hauv DC ceev txoj cai belongs rau tas li torque ceev tswj (qhov tso zis torque ntawm lub cev muaj zog yog yeej tsis hloov)
- Thaum kho qhov excitation voltage, nws belongs rau qhov kev tswj fais fab ceev ceev (lub zog tso zis ntawm lub cev muaj zog tsis hloov pauv)
T = 9.55 * P / N, T tso zis torque, P zog, N ceev, lub cev muaj zog load muab faib ua lub zog tas li thiab transverse torque, tas li torque, T tseem tsis hloov, ces P thiab N yog proportional.Lub load yog tas li lub zog, ces T thiab N yog qhov pib inversely proportional.
Torque = 9550 * tso zis zog / tso zis ceev
Hwj chim (Watts) = Ceev (Rad/sec) x Torque (Nm)
Qhov tseeb, tsis muaj dab tsi los tham, muaj ib qho qauv P = Tn / 9.75.Chav tsev ntawm T yog kg·cm, thiab torque = 9550 * tso zis zog / tso zis ceev.
Lub zog yog qhov tseeb, qhov nrawm nrawm, thiab lub zog me me.Feem ntau, thaum yuav tsum muaj lub zog loj, ntxiv rau lub cev muaj zog nrog lub zog siab, yuav tsum muaj tus reducer ntxiv.Nws tuaj yeem nkag siab zoo li no tias thaum lub zog P tsis hloov pauv, qhov siab dua qhov ceev, qhov me me ntawm qhov tso zis torque.
Peb tuaj yeem suav nws zoo li no: yog tias koj paub lub zog torque T2 ntawm cov khoom siv, qhov ntsuas ceev n1 ntawm lub cev muaj zog, qhov ceev n2 ntawm cov zis tawm, thiab cov khoom siv tsav tsheb f1 (qhov no f1 tuaj yeem txhais raws li qhov tseeb. Kev ua haujlwm ntawm qhov chaw, feem ntau ntawm cov neeg nyob hauv tsev yog siab dua 1.5) thiab lub zog ua haujlwm m ntawm lub cev muaj zog (uas yog, qhov sib piv ntawm lub zog ua haujlwm rau tag nrho lub zog, uas tuaj yeem nkag siab tias qhov ntau npaum li cas hauv lub cev muaj zog winding, feem ntau. ntawm 0.85), peb suav nws lub cev muaj zog P1N.P1N> = (T2 * n1) * f1 / (9550 * (n1 / n2) * m) kom tau txais lub zog ntawm lub cev muaj zog koj xav xaiv lub sijhawm no.
Piv txwv li: lub zog xav tau los ntawm cov khoom siv tsav tsheb yog: 500N.M, kev ua haujlwm yog 6 teev / hnub, thiab cov khoom siv tsav tsheb coefficient f1 = 1 tuaj yeem xaiv nrog ib qho kev thauj khoom, lub reducer xav tau flange installation, thiab cov zis ceev n2 = 1.9r/min Ces tus piv:
