Yintoni i-clearance kwaye ukukhutshwa kulinganiswa njani iibheringi eziqengqelekayo?

Ukucocwa kwe-rolling bearing yilona xabiso liphezulu lomsebenzi obambe indandatho enye kwindawo kunye nenye kwi-radial okanye i-axial direction. Owona msebenzi uphezulu kwicala le-radial ubizwa ngokuba yi-radial clearance, kwaye owona msebenzi uphezulu kwicala le-axial ubizwa ngokuba yi-axial clearance. Ngokuqhelekileyo, i-radial clearance inkulu, i-axial clearance inkulu, kwaye ngokuphambeneyo. Ngokwemeko yokuthwala, imvume inokwahlulwa ngokwezi ntlobo zintathu zilandelayo:

I. Isiqinisekiso sokuqala

Ukukhutshwa kwamahhala phambi kokufakwa kokufakwa. Ukucocwa kwasekuqaleni kugqitywe ngokucutshungulwa komenzi kunye nokudibanisa.

2. Faka i-clearance

Ekwabizwa ngokuba yi-fit clearance, lucociso xa i-bearing and shaft kunye ne-bearing house ifakiwe kodwa ayikasebenzi. Ukukhutshwa kokunyuka kuncinci kunokukhutshwa kokuqala ngenxa yokuphazamiseka kokunyuka, mhlawumbi ukwandisa iringi yangaphakathi, ukunciphisa iringi yangaphandle, okanye zombini.

3. Ukukhutshwa komsebenzi

Xa ukuthwala kukwimeko yokusebenza, ukushisa kwendandatho yangaphakathi kuphakama ukuya kwinqanaba eliphezulu kunye nokwandiswa kwe-thermal ukuya kwinqanaba eliphezulu, ukwenzela ukuba imvume yokuthwala iyancipha. Ngexesha elifanayo, ngenxa yomphumo womthwalo, i-elastic deformation iyenzeka kwindawo yokudibanisa phakathi komzimba ojikelezayo kunye nomzila wokugijima, okwandisa ukukhutshwa kwe-bearing clearance. Ingaba i-bearing clearance yokusebenza inkulu okanye incinci kunokukhutshwa kwe-mounting clearance kuxhomekeke kwisiphumo esidityanisiweyo sale miba mibini.

Ezinye iibheringi eziqengqelekayo azikwazi ukulungiswa okanye ukuqhawuka. Zifumaneka kwiimodeli ezintandathu, ukusuka kwi-0000 ukuya kwi-5000; Kukho uhlobo lwe-6000 (ii-angular contact bearings) kunye nohlobo lwe-1000, Uhlobo lwe-2000 kunye noHlobo lwe-3000 kunye nemingxuma ye-cone kwindandatho yangaphakathi. Ukunyuswa kokunyuka kwezi ntlobo zeebherethi eziqengqelekayo, emva kokulungelelaniswa, kuya kuba kuncinci kunokukhutshwa kokuqala. Ukongeza, ezinye iibheringi zinokususwa, kwaye imvume 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). Akukho mvume yokuqala kwezi ntlobo zintathu zeebheringi. Kuhlobo lwe-6000 kunye nohlobo lwe-7000 yeebheringi eziqengqelekayo, ukukhutshwa kwe-radial kuncitshisiwe kwaye ukucocwa kwe-axial kuncitshisiwe, kwaye ngokuchaseneyo, ngelixa uhlobo lwe-8000 kunye nohlobo lwe-9000 yeebheringi eziqengqelekayo, kuphela i-axial clearance ibaluleke kakhulu.

Ukukhutshwa okufanelekileyo kokunyuka kuququzelela ukusebenza okuqhelekileyo kwe-rolling bear. Ukucocwa kuncinci kakhulu, ukushisa kwe-rolling kukhuphuka, akukwazi ukusebenza ngokuqhelekileyo, ukwenzela ukuba umzimba ojikelezayo unamathele; Ukususwa okugqithisileyo, ukungcangcazela kwezixhobo, ingxolo eqengqelekayo.

Indlela yokuhlola i-radial clearance yile ilandelayo:

I. Indlela yovakalelo

1. Ngesandla esijikelezayo, ukuthwala kufuneka kube lula kwaye kuguquguquke ngaphandle kokunamathela kunye ne-astringency.

2. Vuthulula iringi yangaphandle yebheringi ngesandla. Nangona i-radial clearance i-0.01mm kuphela, ukuhamba kwe-axial kwinqanaba eliphezulu lokuthwala ngu-0.10-0.15mm. Le ndlela isetyenziselwa umqolo omnye iibheringi zebhola ezisembindini.

Indlela yokulinganisa

1. Khangela kwaye uqinisekise isikhundla esiphezulu somthwalo we-rolling bearing kunye ne-fealer, faka i-fealer phakathi komzimba ojikelezayo we-180 ° kunye nendandatho yangaphandle (yangaphakathi), kunye nobukhulu obufanelekileyo be-feander yi-radial clearance ye-bearing. Le ndlela isetyenziswa ngokubanzi kwiibheringi zokuzilungelelanisa kunye neebheringi ze-cylindrical roller.

I-2, jonga ngesalathisi sokudayela, kuqala usethe isalathisi sokudayela kwi-zero, emva koko uphakamise i-ring bearring yangaphandle, ukufundwa kwesalathisi sokudayela kukukhutshwa kwe-radial ye-bearing.

Indlela yokuhlola i-axial clearance yile ilandelayo:

1. Indlela yovakalelo

Jonga i-axial clearance ye-rolling bearing ngomnwe wakho. Le ndlela kufuneka isetyenziswe xa isiphelo se-shaft sibonakalisiwe. Xa i-shaft end ivaliwe okanye ayikwazi ukujongwa ngeminwe ngenxa yezinye izizathu, khangela ukuba i-shaft iguquguqukayo ngokujikeleza.

2. Indlela yokulinganisa

(1) Jonga ngesixhobo sokuziva. Indlela yokusebenza iyafana naleyo yokujonga ukucocwa kweradial nge-feel, kodwa ukucocwa kwe-axial kufuneka kube

C = lambda/sono (2 beta)

Apho c -- i-axial clearance, mm;

-- Ubukhulu begeyiji, mm;

-- I-engile yekhowuni, (°).

(2) Khangela ngesalathisi sokudayela. Xa i-crowbar isetyenziselwa ukuhambisa i-shaft ehambayo kwiindawo ezimbini ezigqithiseleyo, umahluko wokufunda isalathisi sokucofa kukucocwa kwe-axial yokuthwala. Nangona kunjalo, amandla asetyenziswe kwi-crowbar akufanele abe mkhulu kakhulu, ngaphandle koko igobolondo iya kuba ne-elastic deformation, nokuba i-deformation incinci kakhulu, iya kuchaphazela ukuchaneka kwe-axial clearance.
