Universal log nres uas yog, universal pob qij txha, yog kom paub qhov sib txawv ntawm lub kaum sab xis ntawm lub hwj chim kis tau tus mob ntawm lub tshuab, rau qhov yuav tsum tau hloov txoj hauj lwm ntawm cov kev taw qhia ntawm tus tsav ncej kab, nws yog lub automotive tsav system ntawm lub universal kis ntaus ntawv "sib koom. "cov khoom siv.Universal log nres thiab tsav ncej ua ke, hu ua universal sib koom tes kis tau tus mob.Universal log nres kis tau tus mob yog feem ntau tsim los ntawm universal pob qij txha thiab tsav shafts, thiab tej zaum intermediate kev txhawb nqa, feem ntau yog siv nyob rau hauv ib co ntawm cov nram qab no txoj hauj lwm: 1-universal pob qij txha;2-tsav shafts;3- pem hauv ntej tsav ncej;4-kev txhawb nqa nruab nrab.Nyob rau hauv ib tug universal sib koom haum, kev sib hloov ntawm ib feem (tso zis ncej) nyob ib ncig ntawm nws tus kheej ncej yog tsav los ntawm kev sib hloov ntawm lwm yam universal sib koom tes (input ncej) nyob ib ncig ntawm nws ncej.
Universal log braking nyob rau hauv cov kev taw qhia ntawm torsion seb puas muaj tseeb elasticity yuav muab faib mus rau hauv nruj universal pob qij txha thiab saj zawg zog universal pob qij txha.Rigid universal pob qij txha tuaj yeem muab faib ua cov pob qij txha tsis sib xws (feem ntau siv rau hom ntoo khaub lig), quasi-sib npaug ceev universal pob qij txha (xws li duplex universal pob qij txha) thiab sib npaug ceev universal pob qij txha (xws li pob tawb hom universal pob qij txha) peb .Universal pob qij txha nyob rau hauv uas lub kaum sab xis ntawm ob lub shafts txuas los ntawm lub universal nres yog ntau tshaj xoom, thiab cov zis thiab input shafts hloov mus rau ib tug sib txawv instantaneous angular tshaj tawm piv, tab sis qhov nruab nrab angular velocities yog sib npaug.
Hla-axis hom nruj universal pob qij txha yog tsim los ntawm universal sib koom diav rawg, hla ncej, koob rau cov menyuam bearing, roj foob, txheej yooj yim, bearing npog thiab lwm yam khoom.Lub hauv paus ntsiab lus ntawm kev ua haujlwm yog raws li hauv qab no: ib qho ntawm cov diav rawg rotating lwm rab rawg tig los ntawm tus ntoo khaub lig ncej, thiab tib lub sijhawm, nws tuaj yeem ua viav vias ib ncig ntawm qhov nruab nrab ntawm tus ntoo khaub lig ncej ntawm txhua qhov kev taw qhia.Thaum lub sij hawm kev sib hloov, cov koob chais rau hauv rab koob bearings tuaj yeem tig los txo kev sib txhuam.Cov ncej txuas nrog lub zog hluav taws xob yog hu ua input shaft (tseem hu ua active ncej), thiab cov zis tawm los ntawm kev sib koom ua ke universal hu ua lub tso zis ncej (tseem hu ua cov ncej tsav).Lub universal nres ua haujlwm nyob rau hauv tej yam kev mob uas muaj ib lub kaum sab xis ntawm lub input thiab tso zis shafts, qhov twg lub angular velocities ntawm ob shafts yog tsis sib npaug, thiab raws li qhov tshwm sim tuaj yeem ua rau torsional kev co ntawm cov zis ncej thiab cov khoom sib txuas nrog rau nws thiab cuam tshuam. lub neej ntawm cov khoom no.Nws yog hais txog lub universal nres uas xa cov lus tsa suab ntawm qhov sib npaug instantaneous angular tshaj tawm ntawm lub kaum sab xis tsim thiab ntawm kwv yees li sib npaug instantaneous angular velocities ntawm lwm lub ces kaum.Nws yog subdivided rau hauv:
(a) Duplex hom quasi-sib npaug ceev universal pob qij txha.Nws yog hais txog lub universal sib koom ua ke nyob rau hauv uas qhov ntev ntawm tus tsav ncej nyob rau hauv lub universal sib npaug sib npaug ceev tsav yog shortened mus rau qhov tsawg kawg nkaus.
b) Pob hom quasi-isochronous universal pob qij txha.Los ntawm ob lub universal pob qij txha thiab ob qhov sib txawv ntawm cov pob zeb muaj pes tsawg leeg.Ob lub pob yog sib npaug rau qhov nruab nrab tsav ncej thiab ob tus ntoo khaub lig pins hauv lub tshuab duplex universal sib koom ua ke.
(c) Peb-pin hom quasi-isochronous universal pob qij txha.Nws muaj ob peb-pin shafts, nquag eccentric ncej diav rawg thiab tsav eccentric ncej diav rawg.
(d) Spherical roller type quasi-isokinetic universal joint.Nws muaj tus pin ncej, kheej kheej cov menyuam, universal sib koom ncej thiab lub tog raj kheej.Cov menyuam tuaj yeem txav axially hauv qhov zawj, ua si lub luag haujlwm ntawm kev nthuav dav spline.Roller thiab zawj phab ntsa tiv tauj tuaj yeem hloov torque.Universal pob qij txha nyob rau hauv uas cov zis thiab input shafts kev cob cog rua los ntawm lub universal nres kis cov lus tsa suab ntawm ib txwm sib npaug instantaneous angular velocities.
