Tlhaloso ea bere le seo e se bolelang

 

Jwalebearingmohlala o ntse o eketseha butle-butle ka litlhoko tse fapaneng tsa batho ba hona joale, 'me joale marang-rang a ntlafalitsoe haholo, phetiso ea tlhahisoleseling le eona e potlakile haholo, 'me ho bonolo ho tseba mohlala oa bearing. Ka mor'a moo, re tla u tsebisa khoutu ea motheo, khoutu ea poso, khoutu ea pele le tsebo e 'ngoe e amanang le bearing.

 

Ho beatlhaloso le moelelo oa eona Likarolo tsa tlhaloso ea ho jara

 

Thebearingmohlala ka kakaretso o na le khoutu ea pele, khoutu ea motheo le khoutu ea poso. Ka kakaretso, tlhaloso ea bearing e bontšoa feela ke tlhaloso ea motheo. Mohlala oa motheo ka kakaretso o na le likarolo tse tharo, khoutu ea mofuta, khoutu ea boholo le khoutu ea bophara ba ka hare. Khoutu ea poso ke ho sebelisa litlhaku le linomoro ho bontša sebopeho, mamello le litlhoko tse khethehileng tsa thepa. Khoutu ea selelekela e sebelisoa ho bontša likaroloana tsa bearing, tse bontšitsoeng ka litlhaku.

 

Mokhoa oa ho Khetholla Bearing ea Morero o Akaretsang (Rolling Bearing)

 

E arotsoe ka: khoutu ea pele, khoutu ea motheo le khoutu ea poso.

 

1. Lebitso la motheo la khoutu

 

(Khoutu ea mofuta, khoutu ea boholo, khoutu ea bophara ba ka hare [linomoro tse 2])

 

Khoutu ea motheo e sebelisoa ho bontša bophara ba ka hare, letoto la bophara, letoto la bophara le mofuta oa ho jara, ka kakaretso ho fihlela ho linomoro tse hlano, ka tsela e latelang:

 

1) Bophara ba kahare ba bearing bo bontšoa ke nomoro ea pele ho tloha ka letsohong le letona la khoutu ea motheo. Bophara ba kahare ba bearing bo nang le bophara bo tloaelehileng ba kahare ba d=20~480mm hangata ke palo e ngata ea 5, 'me linomoro tsena tse peli li emela quotient ea boholo ba bophara ba kahare ba bearing bo arotsoeng ka 5, joalo ka 04 means d=20mm; 12 means d=60mm, jj. Bakeng sa li-bearing tse nang le bophara ba kahare ba 10mm, 12mm, 15mm le 17mm, likhoutu tsa bophara ba kahare ke 00, 01, 02 le 03 ka ho latellana. Bakeng sa li-bearing tse nang le bophara ba kahare bo ka tlase ho 10mm le ho feta 500mm, mokhoa oa ho hlahisa bophara ba kahare o hlalositsoe ka tsela e 'ngoe, ka kopo sheba GB/T272-93.

 

2) Letoto la bophara ba bearing (ke hore, letoto la diphetoho bophara ba kantle le bophara ba bearing tse nang le sebopeho se tshwanang le bophara ba kahare bo tshwanang) le bontshwa ke nomoro ya boraro ho tloha ka letsohong le letona la khoutu ya motheo. Mohlala, bakeng sa dibearing tsa radial le radial thrust, 0 le 1 di bontsha letoto la lesedi le eketsehileng; 2 e bontsha letoto la lesedi; 3 e bontsha letoto la mahareng; 4 e bontsha letoto le boima. Papiso ya boholo pakeng tsa letoto e bontshwa setshwantshong se ka tlase. Dibearing tsa Thrust ntle le 1 ho emela letoto la lesedi, tse setseng le dibearing tsa radial di a tshwana.

 

3) Letoto la bophara ba bearing (ke hore, letoto la diphetoho bophara ba bearing ka sebopeho se tshwanang, bophara ba kahare le letoto la bophara) le bontshwa ke nomoro ya bone ho tloha ka letsohong le letona la khoutu ya motheo. Ha papiso ya letoto la bophara ba letoto la bophara ho Setšoantšo sa 13-4 e thathamisitswe e le letoto la 0 (letoto le tlwaelehileng), khoutu ya letoto la bophara O e ke ke ya tshwauwa khoutung bakeng sa dibearing tse ngata, empa bakeng sa dibearing tsa roller tse chitja le dibearing tsa roller tse tapered, khoutu ya letoto la bophara 0 e lokela ho tshwauwa.

 

Dikhoutu tsa letoto la bophara le dikhoutu tsa letoto la bophara di bitswa dikhoutu tsa letoto la tekanyo.

 

4) Khoutu ea mofuta oa bearing e emetsoe ke nomoro ea bohlano ho tloha ka letsohong le letona la khoutu ea motheo (bakeng sa li-bearing tsa cylindrical roller le li-bearing tsa nale roller, khoutu ke tlhaku).

 

2. Khoutu ea poso

 

Khoutu ea poso ea bearing ke ho sebelisa litlhaku le linomoro ho bontša sebopeho, mamello le litlhoko tse khethehileng tsa thepa. Ho na le litaba tse ngata tsa likhoutu tsa poso, 'me mona ke mabitso a' maloa a likhoutu a sebelisoang hangata.

 

1) Khoutu ea sebopeho sa kahare e reretsoe ho bontša sebopeho se fapaneng sa kahare sa mofuta o tšoanang oa bearing, e bontšitsoeng ka litlhaku tse lateloang ke khoutu ea motheo. Mohlala, li-bearing tsa bolo ea ho ikopanya tse nang le likhutlo tsa ho ikopanya tsa 15°, 25° le 40° li emeloa ke C, AC le B ka ho latellana ho emela phapang sebopehong sa kahare.

 

2) Kereiti ea mamello ea bearing e arotsoe ka lihlopha tse 2, lihlopha tse 4, lihlopha tse 5, lihlopha tse 6, lihlopha tse 6X le lihlopha tse 0, kakaretso ea lihlopha tse 6, ho tloha holimo ho ea tlaase, 'me likhoutu tsa tsona ke /PZ, /P4, /PS, /P6, /P6X le /PO. Har'a lihlopha tsa mamello, sehlopha sa 6X se sebetsa feela ho li-bearing tsa roller tse tapered; Boemo ba 0 ke sehlopha se tloaelehileng, se sa tšoauoang khoutung ea ho jara mabili.

 

3) Letoto la di-bearing radial clearance tse sebediswang hangata le arotsoe ka sehlopha se le seng, dihlopha tse 2, dihlopha tse 0, dihlopha tse 3, dihlopha tse 4 le dihlopha tse 5, kakaretso ya dihlopha tse 6, mme clearance ya radial e tloha ho e nyane ho isa ho e kgolo. clearance ya sehlopha sa o ke sehlopha sa clearance se sebediswang hangata, se sa tshwauwang khoutung ya bearing, mme dihlopha tse ding tsa clearance di emelwa ke /CI, /CZ, /C3, /C4 le /CS khoutung ya bearing.

 

3. Khoutu ea pele ho nako

 

Selelekela sa ho bea se sebediswa ho bontsha dikarolo tse nyane tsa bea, tse bontshwang ka ditlhaku. Mohlala, L e sebediswa ho emela lesale le ka arolwang la bea e ka arolwang; K e bontsha dikarolo tse pitikolohang le dikarolo tsa lesaka tsa bea, jj.

 

Ho na le mefuta e mengata ea li-rolling bearings lits'ebetsong tse sebetsang, 'me li-bearings tse tsamaellanang le tsona li rarahane haholo. Khoutu e hlahisitsoeng kaholimo ke karolo ea motheo le e sebelisoang haholo ea khoutu ea bearings, 'me u ka khetholla le ho hlahloba bearings e sebelisoang hangata haeba u tloaelane le karolo ena ea khoutu. Bakeng sa mokhoa o qaqileng oa khoutu ea li-rolling bearings, ka kopo sheba GBT272-93.
