Ubungakanani be-roller bearing etywiniweyo onokukhetha njani?
Xa ukhetha i-bearing, idla ngokukhethwa ngokwendlela yoomatshini, inxalenye, iinkcukacha ze-spindle, uhlobo lwe-bearing, indlela yokuthambisa kunye nendlela yokuqhuba, kunye nezinye iimeko, emva kokuba ubomi be-bearing, ukuchaneka, ukuqina, isantya esiyingozi kunye neminye imisebenzi ifundwe kwaye ivavanywe.
I-roller bearing ehambelanayo etywiniweyo
Amanyathelo okukhetha aqhelekileyo ngala alandelayo:
1, Ukuze ukwazi kakuhle iimeko zokusetyenziswa kweebheringi nokuqwalasela uhlobo lweebheringi, kudla ngokufuneka umisele umsebenzi kunye nolwakhiwo lwesixhobo soomatshini, ukusetyenziswa kweebheringi, indawo evumelekileyo, ubungakanani kunye necala lomthwalo, inqanaba lokubaleka kunye nefuthe, isantya, ubushushu bokusetyenziswa, iimfuno zokuqina, uqwalaselo lwebheringi (isiphelo esimiselweyo okanye isiphelo esikhululekileyo), ukuthambekela kweeringi zangaphakathi nezangaphandle, kunye nemeko yohlahlo lwabiwo-mali. Ngale meko yokusetyenziswa, uhlobo lwebheringi kunye noqwalaselo olufanelekileyo lunokugqitywa kwangaphambili.
Umzekelo, ukusetyenziswa kwezinto ezingcolisiweyo, ezimanzi, cinga ngesigqubuthelo esivaliweyo, ukukhethwa kwegrisi eqinileyo, kwaye ngokwendlela yokusetyenziswa kobushushu, ukhetho lokuthambisa oluhambelana ngokucacileyo, ukuvumela indawo encinci, cinga ngeebheringi ezimxinwa okanye ezincinci, ngokwendlela yobukhulu bomthwalo, khetha Ukuqhamisa ibholaiibheringi ze-s okanye ze-roller, iibheringi ze-bronze, njl.njl., i-pulsation kunye ne-impact degree, zichonge i-clearance ehambelanayo, isantya sokumisela imo yoqhagamshelwano, izixhobo zokukhetha eziqinileyo njalo njalo.
Indawo engcoliswe kakhulu
Emva kokucacisa uhlobo lokusetyenziswa kweebhereyitha okokuqala ngokwemiqathango yokusetyenziswa, kuyimfuneko ukucacisa iinkcukacha zeebhereyitha ngokweenkcukacha ezilandelayo:
2, cinga ngobukhulu bebheri, ngokwendlela obuyilwe ngayo isixhobo soomatshini, isantya esilinganiselweyo, umthwalo we-radial kunye ne-axial, umthwalo oguqukayo nongaguqukiyo, kunye nokhuseleko, misela ubungakanani obuthile bebheri, ngokwembono, isantya esilinganiselweyo siphezulu, ibhola likhulu, izangqa zangaphakathi nezangaphandle zikude, umthwalo uphezulu, ibhola ixinene ngakumbi, okanye umthwalo uphezulu, umzimba ojikelezayo we-roller okanye Irola yenaliti incinci, izangqa zangaphakathi nezangaphandle zibanzi, Isantya esihambelanayo siya kuncitshiswa, kukho umthwalo omncinci we-axial, cinga nge-flange, okanye i-cone Angle, kwaye ekugqibeleni umisele ubungakanani bebheri.
3, cinga ngokuchaneka kwebheri, ngokusebenzisa ukuchaneka kokujikeleziswa kweshaft, isantya, utshintsho lwe-torque, ukumisela ukuchaneka kwebheri, ikakhulu ithiyori enxulumene nokuziqhelanisa, ukuchaneka kwe-spindle yeyona nto ibalulekileyo, phantsi kwengcamango ye-spindle echanekileyo kakhulu, ngokubanzi, kokukhona ukuchaneka okuphezulu, isantya sikhawuleza, ingxolo incinci, kokukhona ixabiso liphezulu.
4, cinga ngokususwa kwangaphakathi kwebheriyali, ngokusebenzisa izinto kunye nokuma kweshaft kunye nebhokisi yebheriyali, ukuthambekela kwezangqa zangaphakathi nezangaphandle, umahluko wobushushu, ukulingana kwebheriyali, ubungakanani bomthwalo wangaphambi kokulayisha, ukumisela ukususwa kwebheriyali.
Imeko yokusebenza enzima
5, cinga ngekheji, ngesantya, ukubetha, impembelelo, isandi, ukuthambisa, uhlobo olucacileyo lwekheji kunye nezinto.
6. Cinga ngendlela yokuthambisa, ngokusebenzisa ubushushu, indlela yokutywina, isantya, indlela yokuthambisa, indawo yokusetyenziswa, indlela yokuthambisa ecacileyo kunye ne-lubricant, kwaye umisele indlela yokutywina yebheri.
7, cinga ngeenkcukacha ezikhethekileyo, ukuba i-bearing isetyenziswa kwiimeko ezithile ezikhethekileyo, ezinje ngamakhulu okanye amawaka eedigri zobushushu obuphezulu kakhulu, okanye amashumi eedigri ezingaphantsi kwe-zero okanye i-degree enye okanye amakhulu amabini eedigri ezingaphantsi kwe-zero zobushushu obuphantsi kakhulu, okanye isetyenziswa kwiindawo zomoya ezifana nendawo engenazintsholongwane, ii-workshops zamayeza, okanye isithuba sangaphandle, i-spacecraft, kufuneka ukhethe izixhobo ezikhethekileyo ngokweenkcazo ezikhethekileyo, thatha ubushushu obuphezulu kakhulu njengomzekelo. Ukuba bubushushu obuphezulu kakhulu ngoko nangoko, udinga i-coating yobushushu obuphezulu, ukuba bubushushu obuphezulu kakhulu ixesha elide, kufuneka u-odole i-tungsten, i-rhenium, i-osmium kunye nezinye izinto zesinyithi ezixabisekileyo ze-bearing.
Okwangoku, imodeli yokuthwala sele imiselwe ngokusisiseko, kwaye ekugqibeleni kufuneka kuqwalaselwe ukufakwa kunye nokuqhekeka kweebheringi, ngokwemeko yokufakela ukuze kuchongwe ubungakanani obufanelekileyo, ukufakwa kweebheringi ezicacileyo kunye namanyathelo.
