Yintoni i-clearance kwaye i-clearance ilinganiswa njani kwi-rolling bearings?

Ukususwa kwe-rolling bearing sisixa esiphezulu somsebenzi esibamba indandatho enye endaweni yayo kwaye enye ibambe kwicala le-radial okanye le-axial. Umsebenzi ophezulu kwicala le-radial ubizwa ngokuba yi-radial clearance, kwaye umsebenzi ophezulu kwicala le-axial ubizwa ngokuba yi-axial clearance. Ngokubanzi, okukhona i-radial clearance inkulu, kokukhona i-axial clearance inkulu, kwaye ngokuchaseneyo. Ngokwemeko ye-bearing, i-clearance inokwahlulwa ibe ziintlobo ezintathu ezilandelayo:

I. Imvume yokuqala

Ukususwa kwamahhala ngaphambi kokufakwa kweebheringi. Ukususwa kokuqala kumiselwa yindlela yokucubungula kunye nokudibanisa komenzi.

2. Faka indawo yokucima

Ikwaziwa nangokuba yindawo yokungena, yindawo yokungena xa i-bearing kunye ne-shaft kunye ne-bearing housing zifakiwe kodwa zingasebenzi. Indawo yokungena incinci kunendawo yokungena yokuqala ngenxa yokuphazamiseka kokufakwa, nokuba kukwandisa i-ring yangaphakathi, ukunciphisa i-ring yangaphandle, okanye zombini.

3. Imvume yokusebenza

Xa ibheriyali ikwimeko yokusebenza, ubushushu beringi yangaphakathi bunyuka bufikelele kwinqanaba eliphezulu kwaye ukwanda kobushushu kufikelele kwinqanaba eliphezulu, ukuze isithuba sebheriyali sinciphe. Kwangaxeshanye, ngenxa yesiphumo somthwalo, ukuguquguquka kwe-elastic kwenzeka kwindawo yokunxibelelana phakathi komzimba oqengqelekayo kunye nendlela yokugijima, nto leyo eyandisa isithuba sebheriyali. Nokuba isithuba sokusebenza sebheriyali sikhulu okanye sincinci kunesithuba sokukhweza kuxhomekeke kwisiphumo esidibeneyo sezi zinto zimbini.

Ezinye iibheringi eziqengqelekayo azinakulungiswa okanye ziqhekeke. Zifumaneka kwiimodeli ezintandathu, ukusuka kwi-0000 ukuya kwi-5000; Kukho uhlobo lwe-6000 (iibheringi zoqhagamshelwano ze-angular) kunye nohlobo lwe-1000, Uhlobo lwe-2000 kunye nohlobo lwe-3000 ezineembobo zekhoni kwiringi yangaphakathi. Indawo yokufakelwa kwezi ntlobo zeebheringi eziqengqelekayo, emva kokulungiswa, iya kuba ncinci kunendawo yokuqala yokungena. Ukongeza, ezinye iibheringi zinokususwa, kwaye indawo yokungena ingalungiswa. Kukho iintlobo ezintathu zeebheringi: Uhlobo lwe-7000 (i-tapered roller bearing), uhlobo lwe-8000 (i-thrust ball bearing) kunye nohlobo lwe-9000 (i-thrust roller bearing). Akukho ndawo yokuqala yokungena kwezi ntlobo zintathu zeebheringi. Kwiibheringi eziqengqelekayo zohlobo lwe-6000 kunye nohlobo lwe-7000, indawo yokungena ye-radial iyancitshiswa kwaye indawo yokungena ye-axial nayo iyancitshiswa, kwaye ngokuchaseneyo, ngelixa kwiibheringi eziqengqelekayo zohlobo lwe-8000 kunye nohlobo lwe-9000, indawo yokungena ye-axial kuphela ebaluleke kakhulu.

Ukususwa ngokufanelekileyo kokufakelwa kwenza kube lula ukusebenza okuqhelekileyo kwebheriya yokuqengqeleka. Ukususwa kuncinci kakhulu, ubushushu bebheriya yokuqengqeleka buyanyuka, abukwazi ukusebenza ngokuqhelekileyo, kangangokuba umzimba oqengqelekayo uyabhajwa; Ukususwa okugqithisileyo, ukungcangcazela kwezixhobo, ingxolo yebheriya yokuqengqeleka.

Indlela yokuhlola i-radial clearance yile ilandelayo:

I. Indlela yokuziva

1. Xa i-bearing ijikeleza ngesandla, i-bearing kufuneka igudise kwaye iguquguquke ngaphandle kokunamathela kunye nokuxinana.

2. Shukumisa indandatho engaphandle yebheri ngesandla. Nokuba indawo evulekileyo yi-0.01mm kuphela, intshukumo ye-axial yenqaku eliphezulu lebheri yi-0.10-0.15mm. Le ndlela isetyenziselwa iibheringi zebhola eziphakathi komqolo omnye.

Indlela yokulinganisa

1. Jonga kwaye uqinisekise indawo ephezulu yomthwalo webheri yokuqengqeleka nge-feeler, faka i-feeler phakathi komzimba oqengqelekayo nge-180° kunye neringi yangaphandle (yangaphakathi), kwaye ubukhulu obufanelekileyo be-feeler bubucaba be-radial bearing. Le ndlela isetyenziswa kakhulu kwiibheringi ezizilungelelanisayo kunye neebheringi ze-cylindrical roller.

2, jonga ngesalathisi sokudayela, qala usete isalathisi sokudayela ukuya ku-zero, uze uphakamise iringi yangaphandle yebhereyitha eqengqelekayo, ukufundwa kwesalathisi sokudayela kukukhanya kwe-radial yebhereyitha.

Indlela yokuhlola ye-axial clearance yile ilandelayo:

1. Indlela yokuziva

Jonga indawo evulekileyo ye-axial ye-rolling bearing ngomnwe wakho. Le ndlela kufuneka isetyenziswe xa isiphelo se-shaft siveziwe. Xa isiphelo se-shaft sivaliwe okanye singenakuhlolwa ngeminwe ngenxa yezizathu ezithile, jonga ukuba i-shaft iyaguquguquka na xa ijikeleziswa.

2. Indlela yokulinganisa

(1) Jonga nge-feeler. Indlela yokusebenza iyafana naleyo yokujonga i-radial clearance nge-feeler, kodwa i-axial clearance kufuneka ibe

C = i-lambda/isono (i-beta ezi-2)

Apho c -- indawo yokucoca i-axial, mm;

-- Ubukhulu begeyiji, mm;

-- I-Angle yekhowuni yokuthwala, (°).

(2) Jonga ngesalathisi sedayili. Xa i-crowbar isetyenziselwa ukuhambisa ishaft ehambayo kwiindawo ezimbini ezigqithisileyo, umahluko wokufundwa kwesibonakaliso sedayili kukususwa kwe-axial kwebheri. Nangona kunjalo, amandla asetyenziswa kwi-crowbar akufuneki abe makhulu kakhulu, kungenjalo iqokobhe liya kuba nokuguquguquka okuthambileyo, nokuba ukuguqulwa kuncinci kakhulu, kuya kuchaphazela ukuchaneka kokususwa kwe-axial okulinganisiweyo.
