Yuav ua li cas yog electromagnetic coupling? Daim ntawv thov thiab kho

Coupling - transmitter teb zog los ntawm ib kawg mus rau lwm ncej. Qhov no ntaus ntawv yog nyob rau hauv feem ntau hluav taws xob motors rau lub tsev ntawm cov neeg kho tshuab zog. Universal cov pob qij txha rau kev tsim kho tsis muaj nyob. Nws yuav muaj ntau yam nrhiav thiab tsim nta.

ntaus ntawv

Electromagnetic clutch li lwm yam, yog ib tug compound ntawm cov hauv qab no Cheebtsam:

• ua sau cov vim li cas hwj chim;
• uas tau tsav, hau lub hwj chim no rau regulators.

Yog hais tias cov qhov chaw muaj kev cob cog tsis tsiv, uas koj tau txais ib tug mus tas daim connector.

Nyob rau hauv tsheb clutch lug siv, qhov ob lub ntsiab qhov chaw ntawm uas yog kev cob cog rua ntawm lub fais thiab sib nqus teb. Vim li no cov muaj yog ib tug kev twb kev txuas mus rau lub engine tsis muaj kev siv txhua yam kev quab yuam, raws li nws muab lub peev xwm mus cuag nyob rau hauv thiab ob tog neeg sab nraud txoj haujlwm. Tej zaum electromagnetic coupling tso cai cov kev cai ntawm lub muab zaus nyob rau hauv cov kev tswj system.

Clutches raug muab faib raws li nram no:

• Tswv yim tsav thiab tsav tsheb qhov chaw yog ua mechanically;
• kev twb kev txuas ntawm qhov yooj yim qhov chaw los ntawm txoj kev induction. Tej kev sib txuas lus yog tau vim lub magnetic teb.

Los ntawm mechanically muaj xws li:

• kev sib txhuam. Lub ntsiab yog ib feem ntawm lub lub tes tsho yog nyob ua ke los ntawm electromagnetic rog. Lawv yuav tsum tau sau nrog ib tug sib txawv tus naj npawb ntawm disks, thiab muaj ntau kev sib txhuam nto (conical los yog cylindrical zoo);
• hmoov. Nyob rau hauv cov designs cov uas tau tsav ib feem kev cob cog rua nrog lub tsav tsheb tshwj xeeb ferromagnetic hmoov uas nyob hauv lub chaw ntawm lub Cheebtsam ntawm lub mechanism. Qhov no hmoov yog magnetized thiab nruj nreem tuav qhov chaw;
• iav (lwm lub npe - "claw"). Nyob rau hauv qhov kev txiav txim ntawm lub electromagnet ntsiab ob qhov chaw yog nyob ua ke los ntawm ua rau lawv cov hniav.

Los ntawm induction muaj xws li:

• asynchronous. Nyob rau hauv no mechanism, vim lub muab lub zog ntawm cov uas feem yog tsim nyob rau hauv lub electromagnetic nyhuv uas cov qhev. Qhov no yog ib feem yog hu ua lub ris hauv qab clutch;
• synchronous. Vim qhov kev txiav txim ntawm mus tas li cov hlau nplaum nyob rau hauv ntau qhov chaw ntawm lub qhov chaw nyob rau hauv tus ntawm tshuab tam sim no los ntawm lub kauj, lub teb tsos, tsevneeg ob qhov chaw;
• hysteresis clutch electromagnetic. Raws li lub npe implies, muaj yog lub phenomenon ntawm tsevneeg qhov chaw ntawm lub hysteresis thaum ib tug nyuaj magnetic lub cev magnetization reversal.

Ib yam ntawm cov saum toj no tej ntsiab cai ntawm cov lag luam uas tsis hloov lub hom phiaj tseem ceeb coupling: hloov dua siab tshiab ntawm lub tswv yim zog txhua yam rau hauv nws raws li qhov tso zis.

Txhua yam yuav raug siv rau kev tswj thiab automation tshuab hom couplings.

Ua hauj lwm inductive ntsiab sau raws nkaus Ii lub electric tsav. Yog li ntawd, feem ntau lug siv cov nram qab no:

• ferroporoshkovye nrog electromagnetic tswj;
• electromagnetic clutches.

Ferroporoshkovaya electromagnetically tswj

Rau xws li cov ntsiab lus yuav tsum nqa tawm raws li ib tug kev twb kev txuas yog rigidly thiab nkag tsav los ntawm tus tswv. Nyob rau hauv no txoj kev uas tau mus kho sib hloov mus los ceev ntawm lub tsav mechanism tsis muaj cov teeb liab ntsais nrog tus tsav lub cev muaj zog nws tus kheej ceev.

Tus tsim ntawm lub tom ntej no lub caij. Ob qhov chaw ntawm lub coupling - ib tug hlau thooj voos kheej kheej uas yog magnetic conductors. Cov uas tau tsav ib feem muaj ib tug zawj, uas yog txhab khoom mus rau teb winding. Nws, nyob rau hauv lem, yog kev cob cog rua rau ib lub hwj chim qhov twg los los ntawm txoj kev ris hauv qab ib ncig, ua ke nrog ib tug txhuam. Qhov chaw ntawm qhov chaw ntawm lub ferromagnetic filling sib tov. Nws yuav ua tau ib tug hmoov los yog kua.

hauv paus ntsiab lus ntawm cov lag luam

Thaum noj rau lub kauj DC voltage, tam sim no yog tsim, uas tas excitation flux. Kis tau nws nyob rau ferromagnet magnetization tshwm sim thiab rau tom kawg, tus hais ua ib tug magnetized saw. Chains cov txheej txheem ntawm nyob rau hauv lub magnetic teb kev taw qhia thiab sib nqus teb kab. Cov uas ua kev quab yuam ntawm attraction ntawm lub chains thiab tuas cov coupling qhov chaw. Pin hwj chim nyob ntawm tus nqi ntawm cov tam sim no uas ntws los ntawm lub chains. Nrog ib qho kev nce nyob rau hauv supersaturation tswv yim tam sim no yog cov ntaub ntawv uas ib tug tack zog yog txo, yog li, nws yog tau los mus tsim ib tug caij nrog slippage.

kev sib txhuam

Thaum muaj ib tug kaw quab yuam nyob rau hauv tus neeg kho tshuab coupling, ces qhov khoom muaj peev xwm hu tau ua kev sib txhuam clutch los yog kev sib txhuam. Txuas xws nthuav dav tau nrog xyaw uas ua nyob rau hauv ib tug hnyav load. Structurally, cov ntsiab yuav ua los ntawm ib tug los yog ntau tshaj disks coj txawv nto tsim ntawm tsis sib haum xeeb: raws li ib tug lub tog raj kheej los yog lub khob hliav qab.

hauv paus ntsiab lus ntawm cov lag luam

Phab yuav raug puas, kev cob cog rua electromagnetic teb. Kho lub torque ntawm ib tug clutch tsis tau yuav, nws yog ib tug tsis tu ncua. nws tsis yog tsim kom tsum muab hloov nyob rau hauv tus ntawm kev hloov ntawm cov tam sim no. Ua kom nrov loj lub hwj chim no coupling tau nrog ib tug 30 coefficient.

Electromagnetic unit hlwb tau nyob ntawm lawv daim ntawv thov.

Electromagnetic clutch ETM

Tiv thaiv cov ntaus ntawv thiab ntau yam mechanisms rau overload mem tes tsuas yog muaj peev xwm sawv ntawm no kom meej. Nws thiaj li load losses. Qhov no txoj tsub kom qhov yuav ntawm engine start-up, txawm nyob rau hauv siab loads. electromagnetic clutch yog muab faib rau tiav rau:

• contactless;
• hu;
• nres.

cua txias compressor clutch

Nyob rau hauv pem hauv ntej ntawm lub compressor yog teev nws. Nws muaj lub ntsiab hais: phaj, pulley, ib tug electromagnetic kauj.

Lub phaj yog txuas ncaj qha mus rau tus ncej thiab cov kauj thiab pulley muaj ib qho chaw nyob rau hauv cover. Thaum lub hwj huam mov pib generating ib tug sib nqus teb, lub wafer yog attracted rau lub pulley thiab cov compressor ncej nyob rau hauv tsab ntawv tsa suab. Lub pulley rotates ua ke nrog lub phaj.

Yog hais tias lub magnetic clutch lawm, kho tau yuav tsum tau nqa tawm nws tus kheej. Yuav kom ntse kho nws yog tsim nyog los raug tshawb nrhiav qhov ua kom muaj tus txhaum. Nyob rau hauv cov ntaub ntawv ntawm breakage ntawm lub compressor clutch yuav xav tias tsis hnov tsw ntawm burning thiab hnov lub suab nrov. Feem ntau, knock tshwm sim thaum qhov yuav tsum tau los hloov tus kabmob. Muaj tej kev yuam kev uas yuav tsuas tshawb nrhiav qhov xub ntiag ntawm tus tswv ntawm tshwj xeeb cov khoom.

Yog hais tias muaj yog ib lo lus nug ntawm kev hloov qhov chaw xws li ib tug sib nqus clutch ( "gazelle" yog tsis muaj exception), cov teeb meem uas nrhiav tau qhov tsim nyog cov khoom yuav tsum tsis txhob tshwm sim. Zoo, yog ib tug kho raws tau tshwm sim nyob rau lub sij hawm. Qhov no yuav tsis txhob ntxiv cov nqi nyob rau hauv cov ntaub ntawv ntawm tsis ua hauj lwm ntawm lwm yam qhov chaw ntawm lub engine.
Couplings nyob rau txawv kho vajtse heev sib txawv thiab tsis yuav tsum tau yuam kev rau nws tus kheej-purchase, koj muaj peev xwm hu tau rau lub chaw muab kev pab.

Yog hais tias lub electromagnetic clutch ntawm lub compressor yuav swb, yog vim li cas rau qhov no tej zaum yuav raws li nram no:

• breakage ntawm lub nias phaj thaum nws yog incorrectly tso rau hauv cov kis;
• faulty clutch kiag li, nws muaj peev xwm "hlawv" thiab mob ntawm cov ua ntawm no heev;
• pulley bearings yuav tsum tau hloov.

Electromagnetic coupling yog siv nyob rau hauv kiv cua-txias compressors los yog tsheb kom muaj ib tug tej yam engine kub.

Nws kuj yog siv kom muaj qhov kub thiab txias thaum lub sij hawm tus mob khaub thuas lub sij hawm ntawm lub xyoo, tshwj xeeb tshaj yog yog hais tias tus kiv cua yog muab rau. Nws yuav pab tau kom tsis txhob noj roj los ntawm kev txo hwj chim rau tus kiv cua tsav.
