Toothed coupling: tau thiab nta

Nyob rau hauv txhua mechanism rau tsav lub shafts uas yog muab kev koom tes, nws yog kom qhia qhov txuas daim no yog hu ua ib tug iav coupling.

Yog hais tias muaj yog ob tug shafts yuav tsum tau kev cob cog rua rau tib axis los yog nyob rau lub kaum sab xis mus rau txhua lwm yam, nws yog qhov zoo tshaj plaws yuav tsum tau mus rau cov hloov loads thiab forces ib tug semi-txhav kev twb kev txuas nrog ib tug iav coupling. Ib tug tib hniav clutch yog muab tso rau hauv cov mob uas tsuas yog tus angular xaav tso cai ntawm tus shafts. Yog hais tias muaj yog ib tug yuav tsum tau pab kom txawm peem rau txawm lub radial los yog axial xaav, ces muab tso rau ob zaug xwb clutch. Iav coupling muaj ib tug high kev ntseeg thiab ib tug zoo coj tus kheej muaj peev xwm, raws li nruab nrog ib tug loj tus naj npawb ntawm cov hniav. Tej clutch mechanisms ua hauj lwm zoo nrog poj ceev (cranes, conveyor khoom).

Clutches ntse pab kom txawm peem rau radial, angular thiab axial ncej misalignments, ua tsaug rau lub backlash nyob rau hauv lub meshing hniav thiab bushings kheej. Tag nrho cov qhov chaw, ntawm uas cov tes tsho, ua los ntawm steel: tus ncej txoj kab uas hla mus rau 140 mm - forged, thiab rau cov loj diameters - cam khwb cia. Yuav kom txhim kho txoj kev coj kuj ntawm cov hniav, lawv kub kev kho mob yog nqa tawm, thiab nyob rau hauv lub coupling muab khov roj.

Nyob rau hauv hauv paus ntsiab lus operably iav coupling muaj ntau npaum li cas nyob rau hauv ntau nrog lub driveline, txawm hais tias compensates me angular displacements, tab sis muaj siab torque ib chav tsev ntim.

Nta ntawm iav couplings

Iav coupling muaj ob coupling halves bolted, thiab ob lub tsho tso rau hauv lub nruas tawb. Nruab nrab ntawm lawv lawv yog koom cov hniav ntawm ib tug kheej kheej zoo. Tej couplings yog standardized raws li GOST 5006-55 rau shafts nrog diameters ntawm 40 rau 560 hli. Nws tseem muaj lwm cov txheej txheem rau cov iav couplings, uas yog siv rau cov kev koom ua ke ntawm tag nrho cov CIS lub teb chaws, nyob ntawm seb lub zog, piv txwv li, GOST 50895-96 (Russia), DSTU 2742-94 (Ukraine).

Ntau yam ntawm daim ntawv sau npe thiab txawv uas yuav tsum tau uas siv rau couplings, coj mus rau qhov tseeb hais tias niaj hnub no tus coupling ntawm cov yam ntxwv nta yog muab faib ua ob peb kev faib pab pawg.

Yog li, raws li lub hauv paus ntsiab lus ntawm coupling tej hauj lwm raug muab faib mus rau hauv tas mus li, coupling thiab nws tus kheej-kev tswj, thiab qhov xwm ntawm ua hauj lwm - rau ib qho nyuaj thiab ywj.

Nyob rau tiav yog coupling nrog detachable clip (GOST 5006-55 MH-iav coupling), nrog rau ib-daim tawb thiab ib nrab ncej (GOST 5006-55 - MW).

Rau hauv lub luv luv xaus ntawm tus ncej lub tes tsho los ua lub clutch nyob rau hauv raws li GOST 12080 cylindrical qhov, thiab nyob rau hauv raws li GOST 12081 - tapered.

Tsis tas li ntawd, iav couplings yuav manufactured raws li cov specifications ntawm tus neeg muas zaub. Yog hais tias tus neeg muas zaub xav tau kev pab kom iav coupling, daim duab yuav tsum meej muaj kev cuam tshuam tag nrho cov tsim nyog tsis.

Thaum mounting couplings yuav tsum tau ua raws li uas muaj tej yam ntxwv, nyob rau hauv particular, mounted rau tus ncej yuav tsum tau nqa tawm thaum uas tsis muaj cua sov.

Nyob rau hauv xyoo tsis ntev los, khwb khuav pib siv iav couplings ntawm polymer tebchaw (Capron, caprolon). Nce yooj thiab muaj peev xwm rau ntau evenly faib lub load rau ntawm cov hniav, txo nws hwj nws rau ib tug par nrog cov hlau. Dhau li ntawm tus coupling ntawm polymers muaj dua elektroizlyatsionnye zog thiab tsawg li tsawg tau.
