Ib qho kev sib txuas yog qhov xa tawm ntawm lub zog tig los ntawm ib qho kawg ntawm ib qho mus rau lwm qhov. Cov cuab yeej no muaj nyob rau hauv feem ntau lub tshuab hluav taws xob rau kev faib cov tshuab hluav taws xob. Tsis muaj universal coupling los ntawm kev tsim. Nws tuaj yeem muaj ntau yam duab thiab tsim nta.

Device

Ib qho khoom siv hluav taws xob, zoo li lwm yam, yog kev sib xyaw ntawm cov hauv qab no:

  • ua, sib sau ua ke lub cev muaj zog;
  • qhev uas dhau lub hwj chim no mus rau cov tswj hwm.

Yog hais tias cov khoom no txuas nrog yam tsis hloov, ces qhov yuav txuas mus tas li.

Couplings tau siv dav hauv kev lag luam tsheb, ob qhov tseem ceeb ntawm kev sib txuas hauv qab lub zog hluav taws xob thiab ib qho sib nqus.

Qhov no ua rau nws muaj peev xwm txuas rau lub cev muaj zog yam tsis tas siv lub zog siv tshuab, thiab nws kuj ua rau nws tuaj yeem txuas rau hauv txoj haujlwm ywj pheej. Qee lub sij hawm lub electromagnetic clutch tso cai rau cov kev cai ntawm rotational frequencies nyob rau hauvtswj system.

Type

Couplings raug cais raws li hauv qab no:

  • kev sib txuas ntawm cov tsav thiab cov thawj coj yog ua los ntawm mechanically;
  • kev sib txuas ntawm cov khoom tseem ceeb yog ua nrog kev pab ntawm induction. Qhov kev sib txuas no ua tau vim yog qhov sib nqus.

Mechanical suav nrog:

  • kev sib txhuam. Qhov tseem ceeb ntawm lub clutch no yog tuav ua ke los ntawm electromagnetic rog. Lawv tuaj yeem tsim nrog ntau tus lej sib txawv thiab muaj qhov sib txawv ntawm qhov sib txawv (conical lossis cylindrical);
  • hmoov. Nyob rau hauv cov qauv tsim no, qhov tsav tau txuas nrog rau qhov ua haujlwm nrog cov hmoov ferromagnetic tshwj xeeb, uas ua rau qhov chaw nruab nrab ntawm cov khoom ntawm lub tshuab. Cov hmoov no yog magnetized thiab tuav cov khoom ua ke nruj nreem;
  • toothed (lwm lub npe yog "cam"). Nyob rau hauv qhov kev txiav txim ntawm ib tug electromagnet, ob lub ntsiab yog tuav ua ke los ntawm cov hniav nyob rau ntawm lawv.

Induction hais txog:

  • asynchronous. Nyob rau hauv cov txheej txheem no, vim yog kev sib hloov ntawm qhov ua haujlwm, cov nyhuv electromagnetic yog tsim nyob rau hauv qhov tsav. Qhov no tseem hu ua plam clutch;
  • synchronous. Vim yog qhov kev txiav txim ntawm cov hlau nplaum tas mus li ntawm qhov sib txawv ntawm qhov kawg ntawm qhov no, nyob rau hauv kev cuam tshuam ntawm tam sim no los ntawm lub kauj, ib daim teb tshwm sim uas tuav ob ntu ua ke;
  • hysteresis clutch electromagnetic. Raws li lub npe qhia, kev sib txuas ntawm qhov chaw tshwm sim los ntawm qhov tshwm sim ntawm hysteresis, thaum lub cev muaj zog hlau nplaum yog remagnetized.

Txhua yam ntawm cov ntsiab lus saum toj no ntawm kev ua haujlwm tsis hloov pauvLub hom phiaj tseem ceeb ntawm lub clutch: kev hloov pauv ntawm lub zog ntawm lub zog ntawm cov tswv yim rau hauv nws ntawm cov zis.

Txhua hom kev sib txuas tuaj yeem siv rau kev tswj hwm thiab tsis siv neeg lub tshuab.

Kev ua haujlwm ntawm cov ntsiab lus induction sib haum rau kev ua haujlwm ntawm lub tshuab hluav taws xob. Yog li, cov khoom siv hauv qab no tau siv dav tshaj plaws:

  • ferro-hmoov nrog electromagnetic tswj;
  • electromagnetic kev sib txhuam clutches.

Ferro-hmoov nrog electromagnetic tswj

Rau qhov zoo li no, nws tuaj yeem txuas cov khoom sib txuas ob leeg nruj thiab nrog kev swb ntawm cov tsav los ntawm kev ua.

Vim qhov no, nws tuaj yeem kho qhov nrawm ntawm lub tshuab tsav yam tsis cuam tshuam nrog kev ceev ntawm lub tshuab tsav nws tus kheej.

Cov qauv ntawm lub caij yog raws li hauv qab no. Ob qhov ntawm lub clutch yog steel thooj voos kheej kheej, uas yog sib nqus circuits. Nyob rau hauv qhov tsav muaj ib zawj uas lub excitation winding txuas nrog. Nws, nyob rau hauv lem, yog txuas nrog lub hwj chim qhov chaw uas siv ib tug plam rings ua ke nrog ib tug txhuam. Qhov chaw nruab nrab ntawm cov khoom yog sau nrog ferromagnetic sib tov. Nws tuaj yeem ua hmoov lossis kua.

Txoj Cai Ua Haujlwm

Thaum qhov hluav taws xob tas mus li raug siv rau winding, ib qho tam sim no raug tsim, uas ua rau muaj kev txaus siab tam sim no. Nws dhau los ntawm ferromagnet thiab tom kawg yog magnetized, nws cov khoom tsim cov hlau nplaum sib nqus.

Cov chains tau teem rau hauv kev coj ntawm cov hlau nplaumteb thiab nws cov kab zog. Lub resulting quab yuam ntawm attraction los ntawm cov chains thiab fastens qhov chaw ntawm lub coupling. Lub zog nplaum yog nyob ntawm tus nqi ntawm cov tam sim no uas ntws los ntawm cov saw hlau. Raws li qhov tam sim no tau nce, cov khoom ua supersaturated, cov nplaum quab yuam txo qis, yog li cov khoom plam tuaj yeem tsim.

Kev sib tw

Thaum muaj lub zog kaw hauv kev sib txuas ntawm cov tshuab, ces qhov yuav raug hu ua kev sib txhuam lossis kev sib txhuam clutch. Nws yog qhov ua tau los txuas xws li ib feem nrog cov cav uas tau tsav nyob rau hauv qhov hnyav. Raws li kev tsim qauv, cov ntsiab lus no tuaj yeem tsim los ntawm ib lossis ntau lub disks nrog kev sib txhuam ntawm qhov sib txawv: hauv daim ntawv ntawm lub tog raj kheej lossis lub khob hliav qab.

Txoj Cai Ua Haujlwm

Ntog uas raug kev sib txhuam yog txuas nrog lub tshuab hluav taws xob. Nws yog tsis yooj yim sua kom tswj lub torque ntawm xws li ib tug kev sib txhuam clutch, nws yog tas li. Nws tsis raug hloov pauv raws li kev hloov pauv ntawm qhov loj ntawm qhov tam sim no. Lub clutch no tuaj yeem ua kom muaj zog nrog cov coefficient ntau dua 30.

Electromagnetic ntsiab yog subdivided raws li lawv daim ntawv thov.

ETM electromagnetic clutch

Tsuas yog qhov no tuaj yeem tiv thaiv cov khoom siv thiab ntau yam kev ua haujlwm los ntawm impulse overloads.

Nws txo qis kev poob qis. Qhov no ua rau muaj qhov ua tau zoo ntawm kev pib lub cav txawm tias muaj kev thauj khoom siab. Lub electromagnetic coupling yog subdivided los ntawm kev ua rau hauv:

  • tsis muaj kev sib cuag;
  • contact;
  • brake.

A / C compressor clutch

Nws yog ntsia rau pem hauv ntej ntawm lub compressor. Nws muaj cov ntsiab lus tseem ceeb: lub phaj, lub tshuab rub, lub tshuab electromagnetic.

Lub phaj txuas ncaj qha rau ntawm tus ncej, thiab lub kauj thiab rub tau nyob rau ntawm lub hau pem hauv ntej. Thaum lub hwj huam mov pib, tsim ib qho chaw sib nqus, lub phaj yog attracted rau lub pulley thiab lub compressor ncej pib txav. Lub pulley tig ua ke nrog lub phaj.

Yog tias lub tshuab hluav taws xob sib nqus tawg, koj tuaj yeem kho nws tus kheej.

Rau kev kho kom tiav, koj yuav tsum kuaj xyuas qhov ua rau tsis ua haujlwm. Yog hais tias lub compressor clutch tawg, yuav hnov tsw ntxhiab thiab suab nrov. Feem ntau lub khob tshwm sim thaum yuav tsum tau hloov cov kabmob. Muaj qhov ua tsis tau zoo uas tsuas yog tus tswv tuaj yeem kuaj xyuas nrog cov cuab yeej tshwj xeeb.

Yog tias cov lus nug tshwm sim ntawm kev hloov cov khoom xws li electromagnetic clutch ("GAZelle" tsis muaj kev zam), ces yuav tsis muaj teeb meem nrhiav cov khoom tsim nyog. Zoo, yog tias qhov tawg tau pom nyob rau lub sijhawm. Qhov no yuav zam tsis tau cov nqi ntxiv yog tias tsis ua haujlwm ntawm lwm qhov chaw ntawm lub cav. Cov khoom sib txuas rau cov cuab yeej sib txawv kuj sib txawv, thiab txhawm rau kom tsis txhob ua yuam kev thaum yuav ntawm koj tus kheej, koj tuaj yeem tiv tauj lub chaw pabcuam..

Yog hais tias lub compressor lub electromagnetic clutches poob, vim li cas rau qhov no tej zaum yuav raws li nram no:

  • tawg ntawm lub phaj siab thaum nws tsis raug tso rau hauv qhov sib txawv;
  • lub clutch yog qhov ua tsis tiav, nws tuaj yeem "kub tawm" thiab kuaj pom qhov ua rau qhov no nyuaj heev;
  • Pulley bearings yuav tsum tau hloov.

Electromagnetic kiv cua clutch yog siv nyob rau hauv lub txias ntawm lub tsheb compressors los yog kom ib tug tej yam engine kub.
