Ball BearingKushivirira Kunotsanangurwa

Unonzwisisa here kushivirira uye zvazvinoreva chaizvo?Kana zvisina kudaro, hausi wega.Iwaya anowanzonokorwa mashoko asi kazhinji pasina nzwisiso chaiyoiyo yezvaanoreva.Mawebhusaiti ane tsananguro dzakareruka dzekubereka kushivirira haawanzo shomeka saka takafunga kuzadza gap.Saka, kana iwe uchida kuziva kuti "Zvinoreva Bore Kutsauka" uye "Single Bore Variation" zvinorevei chaizvo?Verenga pamusoro apo tinotarisira kujekesa izvi zvakanyanya.

Kutsauka

Izvi zvinoraira kuti kure kure sei kubva kune zita rezita, kuyerwa chaiko kunobvumirwa kuve.Dimension yezita ndiyo inoratidzwa mubhuku remugadziri semuenzaniso 6200 ine zita rekuti 10mm, 688 ine zita rekuti 8mm zvichingodaro. Miganhu pakutsauka kukuru kubva pazviyero izvi yakakosha zvakanyanya.Pasina mitemo yepasi rose yekushivirira yemabhengi (ISO neAFBMA), zvingave kune mumwe nemumwe mugadziri.Izvi zvinogona kureva kuti iwe unoodha 688 inobereka (8mm bore) wongoona kuti iri 7mm kubereka uye haikwane shaft.Kutsauswa kushivirira kunowanzo bvumira bhora kana OD kuti ive diki asi isina kukura pane yezita dimension.

Kureva Bore/OD Kutsauka

…Uku kushivirira kwakakosha kana uchitarisa kushamwaridzana mhete yemukati uye shaft kana mhete yekunze uye imba.Kutanga iwe unofanirwa kunzwisisa kuti kubereka hakusi kutenderera.Ehe hazvisi kure asi paunotanga kuyera mumamicrons (zviuru zvemirimita) unoona kuti zviyero zvinosiyana.Ngatitorei kubhohwa kwe688 kubereka (8 x 16 x 5mm) semuenzaniso.Zvichienderana nekuti mumhete yemukati unotora kupi kuyerwa kwako, unogona kuverenga chero kupi zvako, toti, pakati pe8mm ne7.991 mm saka chii chaunotora sehukuru hwekubhowa?Apa ndipo panopinda Mean Deviation. Izvi zvinosanganisira kutora zviyero zvakati kuti mundege imwe chete yeradial (tinosvika pairi muminiti) kuyambuka chibhorani kana kuti OD kuenzana kureba kwemhete iyoyo.

Mufananidzo uyu unomiririra ring yemukati.Miseve inomiririra zviyero zvakasiyana-siyana zvakatorwa pabhore nenzira dzakasiyana kuti zvibatsire kuwana saizi inorehwa.Iyi seti yezviyero yakatorwa nemazvo mundege imwe chete yeradial kureva panzvimbo imwe chete nehurefu hwechibhorani.Maseti ezviyero anofanirwawo kutorwa mune akasiyana radial ndege kuti ave nechokwadi chekuti bore iri mukati mekushivirira pamwe nehurefu hwayo.Izvi zvinoshandawo kune zviyero zvemhete dzekunze.

Dhiagiramu iyi inoratidza kuti KWETE sei kuzviita.Chiyero chega chega chakatorwa pane imwe nzvimbo pamwe nehurefu hwemhete inotakura, mune mamwe mazwi, kuyerwa kwega kwega kwakatorwa mune imwe radial ndege.

Zviri nyore, iyo yepakati bore size inoverengerwa sezvizvi:

Izvi zvinonyanya kubatsira kana uchiverenga kushivirira kweshaft pane imwe bore chiyero chinogona kurasisa.

Ngatitii kushivirira kusinganzwisisike kweP0 inobereka +0/-8 microns.Izvi zvinoreva kuti kureba kubereka kunogona kuva pakati pe7.992mm ne8.000mm.Nheyo imwechete inoshanda kune mhete yekunze.

Width Kutsauka

... kana kutsauka kwehupamhi hwemhete yemukati kana yekunze kubva kune dimension yezita.Hapana tsananguro yakawanda inodiwa apa.Sezvine bore uye OD zvimiro, hupamhi hunofanirwa kudzorwa mukati memamwe kushivirira.Sezvo hupamhi kazhinji husinganyanyi kukosha, kushivirira kwakafara pane kubereka kubereka kana OD.Kutsauka pakufara kwe +0/-120 zvinoreva kuti kana ukayera mhete yemukati kana yekunze pane imwe nzvimbo yakatenderedza, toti, 688 (4mm yakafara) inotakura, haifanire kunge yakapamhama kupfuura 4mm (yezita rezita) kana kutetepa kupfuura 3.880mm.

Variation

Kusiyana kushivirira kunovimbisa kutenderera.Mumufananidzo uyu weakaipa kunze-ye-kutenderera 688 yemukati mhete, chiyero chikuru i9.000mm uye diki 7.000mm.Kana tikaverenga zvinoreva kubereka saizi (9.000 + 7.000 ÷ 2) tinouya ne8.000mm.Isu tiri mukati mezvinoreva bhore kutsauka kushivirira asi kubereka kwacho kwaizove kusinga shandiswe saka iwe unoona kuti kutsauka uye kusiyanisa kunogona kuve kusingabatsiri pasina mumwe nemumwe.

Single Bore / OD Kusiyana

... kana zvakanyanya, Bore / OD Diameter Kusiyana mune Imwe Radial Ndege (hongu, ikozvino iwe unoziva zvese nezve imwechete radial ndege!).Tarisa dhayagiramu iri kuruboshwe uko zviyero zvebore zviri pakati pe8.000mm ne7.996mm.Musiyano uripo pakati pehukuru uye diki 0.004mm, saka, iyo bore dhayamita mutsauko mune imwechete radial ndege iyi, ndeye 0.004mm kana 4 microns.

Kureva Bore/OD Diameter Variation

Ok, totenda kureva kubhowekana/OD kutsauka uye imwe bore/OD musiyano, tinofara kuti kutakura kwedu kuri padhuze nekukura chaiko uye kwakatenderedza zvakakwana asi ko kana paine taper yakawandisa pabore kana OD sezvazviri. dhayagiramu iri kurudyi (hongu, yakawedzera zvakanyanya!).Ichi ndicho chikonzero isu zvakare tine zvinoreva bore uye OD kusiyanisa miganho.

Kuti tiwane zvinoreva bore kana OD mutsauko, tinorekodha zvinoreva bore kana OD mune dzakasiyana radial ndege tobva tatarisa mutsauko uripo pakati pehombe nediki.Fungidzira kuti kuruboshwe pano, iyo yepamusoro seti yezviyero inopa chiyero chekubereka saizi ye7.999mm, yepakati i7.997mm uye pasi i7.994mm.Tora diki kubva kune yakakura (7.999 -7.994) uye mhedzisiro ndeye 0.005mm.Yedu yepakati bore musiyano ndeye 5 microns.

Width Variation

Zvakare, zvakananga.Ngatitorei, kune imwe fani, iyo inobvumidzwa hupamhi musiyano ndeye 15 microns.Kana waizoyera hupamhi hwemhete yemukati kana yekunze panzvimbo dzakasiyana-siyana, kuyerwa kukuru hakufanire kudarika 15 microns kukura pane kuyerwa kudiki.

Radial Runout

…yekuungana inotakura mhete yemukati/yekunze chimwezve chinhu chakakosha chekutsungirira.Ngatitii kutsauka kwemhete yemukati neyekunze iri mukati memiganhu uye kutenderera kuri mukati memusiyano unobvumidzwa, ndizvo chete zvatinoda kunetseka nazvo?Tarisa dhayagiramu iyi yerin'i inobereka yemukati.Kutsauswa kwacho kwakanaka uye ndizvo zvakaita kusiyana asi tarisa kuti hupamhi hwemhete hunosiyana sei.Sezvimwe zvese, hupamhi hwemhete haina kunyatsofanana pane imwe neimwe nzvimbo yakatenderedza denderedzwa asi radial runout kushivirira kunoraira kuti izvi zvinogona kusiyana zvakadii.

Inner ring runout

… inoedzwa nekuyera zvibodzwa zvese padenderedzwa rering yemukati panguva imwe chete yachinja apo mhete yekunze yakamira uye ichitora kuyerwa kudiki pane hombe.Iyi radial runout manhamba akapihwa mumatafura ekushivirira anoratidza musiyano mukuru unobvumidzwa.Musiyano mukukobvu kwemhete pano wakawedzeredzwa kuenzanisira pfungwa yacho zvakajeka.

Mhete yekunze inobuda

inoedzwa nekupima zvibodzwa zvese padenderedzwa reringi rekunze panguva imwe chete yachinja apo ring yemukati inenge yakamira uye ichitora kuyerwa kudiki pane hombe.

Face Runout/Bore

Kushivirira uku kunoita kuti nzvimbo inotakura mhete yemukati iri padyo zvakaringana nekona yekurudyi nehuso hwemhete yemukati.Kushivirira manhamba ekumhanya kwechiso / kubereka anongopihwa mabheji eP5 uye P4 chaiyo mamakisi.Mapoinzi ese ari padenderedzwa rimwe remhete yemukati akaboorwa pedyo nechiso anoyerwa panguva imwe chete yekutenderera ukuwo mhete yekunze yakamira.Kubereka kunozopindurwa uye rumwe rutivi rwechibhorani runotariswa.Tora chiyero chikuru kubva pane chidiki kuti uwane kuyerera kwechiso / kubereka kushivirira.

Face Runout/OD

... kana kusiyanisa kwekunze kwe generatrix kurerekera nechiso.Kushivirira uku kunoita kuti mhete yekunze inotakura iri padyo nekona yekurudyi nechiso chemhete chekunze.Nhamba dzekushivirira dzekumhanya kwechiso / OD dzinopihwa P5 uye P4 chaiyo mamakisi.Mapoinzi ese ari padenderedzwa remhete yekunze yakaboorwa padivi pechiso anoyerwa panguva imwe chete yekutenderera apo mhete yemukati yakamira.Kubata kunozoshandurwa uye rumwe rutivi rwemhete yekunze inotariswa.Tora chiyero chakakura kubva pane chidiki kuti uwane kumhanyisa kwechiso / OD kushivirira.

Face Runout/Raceway yakafanana zvikuru asi, panzvimbo pacho, enzanisa kurerekera kwemukati kana yekunze mhete yemujaho wemujaho nechiso chemukati kana chekunze chemhete.
