Kamwe kutenderedza kweinjini crankshaft kukundikana, zvinokanganisa zvakananga mamiriro einjini. Nokudaro, kuchenjerera kunofanira kubhadharwa kune kukundikana kwekutakura kwekutakura. Izvo zvinowanzoitika kukundikana kweiyo rolling bearing zvino kuongororwa sezvinotevera: 1. Pane mukaha pakati pekufamba kwemukati nekunze zvindori zvekutakura uye kupfeka kwezvikamu zvekusangana.

①. Mhete yekunze yekubereka inotenderera. Kuti zvive nyore disassembly uye gungano, mhete yekunze yebheji inotenderera inotora shanduko yekuchinja negomba rechigaro. Iyo yakanyanya kupindira yemhete yekunze yemberi inotakura ndeye 0.035mm, uye iyo yakanyanya kubvumidzwa ndeye 0.013mm. Iyo yakanyanya kupindira yemhete yekunze yekubereka yekumashure ndeye 0.016mm, uye iyo yakanyanya kubvumidzwa ndeye 0.06mm. Pakuunganidza, gomba rechigaro rinofanira kuyerwa, uye kupindira kwayo kana kubvumirwa hakufaniri kudarika mutsara wepamusoro, kana zvisina kudaro gomba rechigaro rinofanira kugadziriswa.

②. Mhete yemukati yekutakura inofamba-famba. Iyo mhete yemukati yekutenderedza inotora kupindirana kunoenderana nejenari. Iyo yakanyanya kupindira yemukati dhayamita yemberi inotakura ndeye 0.055mm, uye kushoma kupindira ndeye 0.012mm. Iyo yakanyanya kupindira yedhayamita yemukati yekumashure inobereka ndeye 0.046mm, uye kushoma kupindira ndeye 0.003mm. Kubva pakuona kwekubatana kwepamusoro, kana kutakura kwave kuparadzaniswa uye kwakaunganidzwa kakawanda, panogona kunge kune mukaha pakati pemhete yemukati yekutakura nejenari, iyo magazini inofanira kugadziriswa isati yashandiswa.

Kana kukwana pakati pebearing and shaft kwakasununguka, vamwe vashandi vanogadzirisa vanoshandisa embossing kana kubaya pamusoro peiyo yakasununguka shaft kuti vapfavise pamusoro peiyo shaft mukuyedza kuwana nzvimbo yakasimba. Izvi hazvingoparadzi chimiro chejometri cheshaft pamusoro, chinoita kuti kutakura kusawane chaiyo nzvimbo yepakati panguva yekuisa uye skews, asiwo iyo fluffed chikamu chinozopedzisira chave chakatsetseka uye chigova chakasununguka. Nzira chaiyo yekugadzirisa ndeyekukuya nekugadzirisa bhuku rekutanga, uye wozokwesha kana kupfapfaidza jenari.

2. Iyo rolling bearing cage yakasakara, yakaremara kana kutyoka

①. Paunenge uchiunganidza zvindori zvemukati uye zvekunze zvekuputira, nekuda kwehuwandu hwakawanda hwekuvhiringidza, mabhora ekutakura anonamirwa mumhete yechigaro, uye cage inotakura inosvinwa nyore nyore panguva yekushanda. Nokudaro, kuyerwa kunofanira kuitwa panguva yegungano kuti ive nechokwadi chekuvhiringidza.

②. Kuzora kweiyo crankshaft bearing is splash type. Kana kutakura kuchishayikwa kana kusina mafuta ekuzora, kunyanya kana mutoro unobata pakutakura wakakura, tembiricha yekutakura inokwira. Kazhinji, kutonhora kwemhete yemukati yekutakura inenge 10 ° C yakakwirira kudarika yemhete yekunze. Nemhaka yokuti kuwedzera kwekushisa kwemhete dzemukati nekunze kwakasiyana, mukaha uri pakati pebhora nemujaho unonyangarika, uye keji inogona kusvina kana kubereka kuri kumhanya. Naizvozvo, kana uchiisa fani, mafuta ekuzora akachena anofanira kuzorwa kumujaho kudzivirira mafuta ekuzora kuti asapfapfaize uye achikonzeresa kukandirana kwakaoma.

3. The rolling bearing raceway uye rolling element surface peeling

①. Peeling kunokonzerwa ne impact load uye alternating stress. Izvo zvinotenderedza zvinhu zvekutakura uye yemukati uye yekunze mhete mijaho zvese zviri pasi pe cyclic pulsating mitoro, zvichikonzera cyclic kuchinja kusangana kushushikana. Kana huwandu hwekunetsekana hunosvika pane imwe kukosha, kuneta spalling kunoitika panzvimbo yekushanda yezvinhu zvinotenderedza kana mukati nekunze mhete mijaho. Kana mutoro wekutakura wakanyanya kukura, kuneta uku kuchawedzera. Mukuwedzera, kana kutakura kwakaiswa zvisizvo uye shaft yakakotama, mujaho unogona kubva. Iyo flywheel uye pulley yeinjini yakashongedzerwa neanopikisa, uye nguva yekutenderera yeinertia inogadzirwa yakaenzana neinotenderera nguva yeinertia inogadzirwa nechikamu chinotenderera cheinjini. Kana iyo nguva yakagadzirwa yeinertia isina kuenzana, injini inozununguka zvakanyanya mushure memoto, izvo zvinozowedzera huwandu hwekutsinhana kushushikana uye kutenderera kwekushushikana, zvichikonzera kuti nhangemutange uye inotenderedza chinhu chinodonha nguva isati yakwana.

Kuti udzivise kupururudza pamusoro pemujaho wemujaho uye zvinhu zvinomonereka, kuwedzera mutoro uye kuzunguzika kusingakodzeri kunofanirwa kudzivirirwa panguva yekushandiswa, throttle uye kumhanya kunofanirwa kushandiswa zvine musoro panguva yekushanda kudzivirira tirakita kubva kubhunduka, uye mabhaudhi emuviri akamisikidzwa anofanirwa kushandiswa. inoongororwa kakawanda kudzivirira kusunungura.

②. Nemhaka yokuti zvidimbu zvekunze zvakaoma zvinowira panzvimbo inofananidzwa yehoko kana pakati penzvimbo inofananidzwa ye shaft nemhete, chimiro chemujaho wacho chakakanganiswa. Chinhu chinomonereka chinoisa kudzvanyirira kukuru pano, zvichikonzera kupera nekukurumidza uye kupeuka kwesimbi kwemujaho wemhete. Rolling bearing chikamu chakanyatsojeka, icho chinonzwa zvakanyanya kune kunze kwenyika. Mukugadzirisa, shandisa jira rakachena, risina-liting wiper. Iyo wiper jira haifanirwe kutsiviwa neshinda yekare yekotoni, nekuti iyo shinda inopera mune yekare shinda yekotoni inosanganiswa nyore mumafuta ekuzora uye kupinda mubereko, izvo zvinokuvadza zvakanyanya. Usati wabatanidza, nyatsochenesa bhuku, buri rechigaro, uye mukati nekunze mhete yebhengi kudzivirira tsvina kupinda panzvimbo inokwira.

③. Kukuvadza kunokonzerwa nekukuvara kwemujaho panguva yekuiswa. Kana panguva yekuisa, kumanikidzwa kunoshandiswa kunoparidzirwa kuburikidza nemhete yekunze uye bhora resimbi, zvinozokonzera makomba muchikamu icho nzira yekumhanya yemhete inobata bhora resimbi. Mhiripiri yakanyungudika uye yakaraswa munguva pfupi. Naizvozvo, maturusi akakosha anofanirwa kushandiswa pakubvisa, uye zvikamu zvinotakura simba zvinofanirwa kuve zvakarurama uye zvakaenzana.

4. Iyo radial uye axial clearance yekutakura inowedzera

Iyo radial uye axial clearances yemabhengi inowedzera, kunze kwekukakavara kwakaoma uye kukwesha kwakanyanya uye kupfeka panguva yekutanga-up. Inonyanya kukonzerwa nekukweshana pakati pesimbi zvidimbu pamusoro pezvikamu uye jecha, guruva uye tsvina mumafuta ekuzora pane anokunguruka zvinhu uye mijaho.

Kutakura kune kuwedzera kwakakosha kwekucheneswa pakati pemhete uye zvinhu zvinotenderedza nekuda kwekupfeka kweabrasive, matte nzvimbo yakaumbwa pamujaho, uye mavanga asina kuenzana akaonekwa. Nzira yekudzivirira ndeyekutsiva mafuta ekuzora nenguva, uye gomba rekuzora rinofanira kunge risina mhepo kudzivirira kupinda kwetsvina.
