Uqhagamshelwano lweNcam okanye uQhagamshelo loMgca? Ubulumko boMechanical obungasemva kweeRolling Bearings

 

Kwihlabathi leiibheringi eziqengqelekayo, indlela amandla adluliselwa ngayo imisela umda ophezulu wokusebenza. Ngokusekelwe kwimo yoqhagamshelwano phakathi kwezinto eziqengqelekayo kunye neendlela zomdyarho, iibheringi eziphambili zinokwahlulwa zibe ziintlobo ezimbini eziphambili: uqhagamshelwano lwenqaku kunye noqhagamshelwano lomgca — zahlukile kungekuphela nje kwisakhiwo kodwa nakwingqiqo yokuthwala umthwalo.

 

Indawo yoQhagamshelwano: Umthamo woMthwalo oguquguqukayo kodwa olinganiselweyo

 

Iibheringi zebhola,Ezimelwe zii-deep groove ball bearings kunye nee-angular contact ball bearings, zidibanisa iibhola kunye neendlela zomdyarho zangaphakathi nezangaphandle 'kwindawo' xa zikhutshiwe; phantsi komthwalo, indawo yoqhagamshelwano iyakhula ibe ngumphezulu omncinci we-elliptical. Olu hlobo loqhagamshelwano lusasaza uxinzelelo ngokulinganayo, okwenza lufaneleke ekusebenzeni ngesantya esiphezulu kunye neemeko zomthwalo ophakathi, kodwa amandla ayo omthwalo anqunyelwe ngokwemvelo yindawo encinci yoqhagamshelwano.

 

Unxibelelwano lomgca: Luqinile kodwa lunendawo 'ebuthathaka'

 

Ngokwahlukileyo koko, ii-roller bearings zifanaiibheringi zerola ezisilindabonisa 'umgca woqhagamshelwano' kwiimeko ezifanelekileyo — i-roller idibana nendlela yokugijima ecaleni komgca othe tye wethiyori kwicala le-axial. Xa ilayishiwe, le ndawo yoqhagamshelwano iba yingxande okanye i-trapezoidal. Ngelixa umthamo womthwalo ngobude beyunithi uphucuka kakhulu, ukuba imiphetho ye-roller ayicutshungulwanga, uxinzelelo loxinzelelo ludla ngokuvela eziphelweni, okukhawulezisa ukudinwa kwaye kunciphisa kakhulu ubomi benkonzo.

 

Impumelelo Ebalulekileyo: Uyilo lweCrown Lusombulula Uxinzelelo Lomda

 

Iibheringi zerola zanamhlanje ezisebenza kakuhle zisebenzisa 'isithsaba' esincinci (okanye utshintsho olufana nomqolo) kumphezulu werola, zilungiselela uqhagamshelwano olucacileyo lomgca wokuqala lube 'luqhagamshelwano lomgca oluguquliweyo.' Olu yilo lunciphisa ngempumelelo uxinzelelo lomphetho wencopho, luvumela umthwalo ukuba usasazwe ngokulinganayo, ngaloo ndlela luphucula kakhulu ubomi bokudinwa kunye nokuzinza okuguquguqukayo. Kwindlela yobunjineli, umlinganiselo we-axis enkulu ye-contact ellipse (2a) kubude berola obusebenzayo (l) udla ngokuthelekiswa ukuze kuqinisekiswe ukuba utshintsho olufanelekileyo lufezekisiwe.

 

Ukususela kwimigaqo esisiseko ukuya kwi-optimization ephucukileyo, ukukhetha phakathi 'kwenqaku' kunye 'nomgca' akusiyo nje umahluko wesakhiwo kodwa bubugcisa bokutshintshiselana ngobunjineli. Kwaye eso sithsaba esibonakala sincinci sisixhobo esiyimfihlo esenza ukuba iibheringi zanamhlanje zibe nobunzima obude kwaye zithembeke kakhulu.
