Angular yekubata bhora inotakura vagadziri vanonzwisisa kuti kuita kweiyo yakakwirira-kumhanya spindle yeCNC simbi yekucheka muchina maturusi kunoenderana neiyo spindle kutakura uye lubrication yayo kusvika pamwero wakawanda.Muchina wemidziyo inotakura indasitiri yekutakura nyika yangu iri kusimukira nekukurumidza, iine marudzi kubva kudiki kusvika kuhombe, mhando yechigadzirwa uye hunyanzvi hwekuita kubva pasi kusvika kumusoro, indasitiri chiyero kubva padiki kusvika kuhombe, uye inyanzvi yekugadzira sisitimu ine zvikamu zvechigadzirwa zvakakwana uye kugadzirwa kunonzwisisika. marongerwo akagadzirwa.Iko kushivirira kwe spindle bearings kune zvishoma.Idzo dzakanyanya kukodzera kubereka gadziriro dzinoda yakanyanya kukwirira kudhiraivha uye nekumhanyisa kugona.Izvo zvinonyanya kukodzera kurongeka kwekutakura kwe shafts yezvishandiso zvemichina.Nekuda kwekuomarara kwayo, kurongeka kwepamusoro, kutakura mutoro wakakwira uye chimiro chakareruka, mabheji anotenderedza haango shandiswe kune maspindle emagetsi ekucheka maturusi emuchina, asiwo anofarirwa neanomhanya-mhanya ekucheka muchina maturusi.Kubva pakuona kwekumhanya kwepamusoro, angular contact ball bearings mu rolling bearings, cylindrical roller bearings ndiyo yechipiri, uye tapered roller bearings ndiyo yakaipisisa.
Bhora (kureva, bhora) reangular contact bhora rine bhora rinotenderera uye rinotenderera, uye rinogadzira centrifugal force Fc uye gyro torque Mg.Nekuwedzera kweiyo spindle kumhanya, iyo centrifugal simba Fc uye gyro torque Mg ichawedzerawo zvakanyanya, izvo zvinozoita kuti kutakura kuburitse kushushikana kukuru kwekusangana, izvo zvinozotungamira mukuwedzera kukakavara kwekutakura, kuwedzera tembiricha kukwira, kuderera kwechokwadi. uye upenyu hupfupi.Nokudaro, kuitira kuvandudza kushanda kwepamusoro-soro kwekutakura uku, kuedza kwose kunofanira kuitwa kudzvinyirira kuwedzera kweFc yayo neMg.Kubva pakuverenga formula yeangular contact ball bearings Fc uye Mg, inozivikanwa kuti kuderedza density yebhora zvinhu, dhayamita yebhora uye kona yekubata kwebhora zvinobatsira kuderedza Fc neMg, saka ikozvino yakakwirira- masipidhi anomhanyisa anowanzo shandisa makona e15° kana 20° Emabhengi madiki ebhora dhayamita.Nekudaro, iyo dhayamita yebhora haigone kuderedzwa zvakanyanya.Chaizvoizvo, inogona kungova 70% yeyakajairwa bhora dhayamita, kuitira kuti irege kunetesa kusimba kwekubereka.Chinhu chinonyanya kukosha ndechekutsvaga kuvandudzwa kwezvinhu zvebhora.
Kuenzaniswa neGCr15 inotakura simbi, density yesilicon nitride (Si3N4) ceramics inongova 41% yehuremu hwayo.Bhora rakagadzirwa nesilicon nitride rakareruka zvakanyanya.Nomuzvarirwo, iyo centrifugal simba uye gyro torque inogadzirwa panguva yekumhanyisa kutenderera idiki zvakare.vakawanda.Panguva imwecheteyo, iyo elastic modulus uye kuoma kwesilicon nitride ceramics ndeye 1.5 nguva uye 2.3 nguva yekutakura simbi, uye coefficient yekuwedzera kwekushisa inongova 25% yesimbi inotakura, iyo inogona kuvandudza kuoma uye hupenyu hwekutakura, asiwo Iyo inofananidzwa yemvumo yekutakura inochinja zvishoma pasi pemamiriro akasiyana ekukwira kwekushisa, uye basa rakavimbika.Mukuwedzera, iyo ceramic inopesana nekupisa kwepamusoro uye haina kunamatira kune simbi.Zviripachena, iyo sphere yakagadzirwa nesilicon nitride ceramic inonyanya kukodzera kutenderera kwekumhanya.Kudzidzira kwakaratidza kuti ceramic ball angular contact ball bearings inogona kuwedzera kumhanya ne25% ~ 35% kana ichienzaniswa neinoenderana nesimbi bhora mabearings, asi mutengo wakakwira.
Munyika dzekunze, mabearings ane simbi yemukati nekunze mhete uye ceramic rolling zvinhu zvinosanganiswa zvinonzi mahybrid bearings.Parizvino, ma hybrid bearings ane zvitsva zvitsva: imwe ndeyokuti zvinhu zveceramic zvakashandiswa kugadzira mabheji e-cylindrical roller bearings, uye ceramic cylindrical hybrid bearings yakaonekwa pamusika;imwe yacho ndeyokushandisa simbi isina tsvina panzvimbo yekutakura simbi kugadzira zvindori zvemukati nekunze zvekutakura, kunyanya mhete yemukati.Sezvo coefficient of thermal kuwedzera kwesimbi isina tsvina idiki 20% pane iyo yekutakura simbi, zvakasikwa, kuwedzera kwekunetseka kwekusangana kunokonzerwa nekuwedzera kwekupisa kwemhete yemukati kuchadzvinyirirwa panguva yekutenderera kwepamusoro.
