Mitundu ndi Kugawa kwa Ma Bearings Ozungulira

 

1. Maberani ozunguliraamagawidwa malinga ndi komwe katundu wawo anganyamulire kapena ngodya yolumikizirana:

 

a) Ma radial bearing — amagwiritsidwa ntchito makamaka kunyamula katundu wa radial, wokhala ndi ngodya yolumikizira ya 0°≤τ≤30°. Malinga ndi ma angles osiyanasiyana olumikizirana, amatha kugawidwa m'magulu awa:

 

1) Mabearings ozungulira olumikizana ndi radial — mabearings okhala ndi ngodya yolumikizira ya nominal τ=0°. Oyenera kunyamula katundu wozungulira komanso okhoza kunyamula katundu waung'ono wa axial mbali iliyonse;

 

2) Mabearings ozungulira a angular contact radial— mabearing okhala ndi ngodya yolumikizirana ya 0°<τ≤30°. Oyenera kunyamula katundu wophatikizidwa ndi zigawo zonse ziwiri za radial ndi axial.

 

b) Maberiyani othyola — amagwiritsidwa ntchito makamaka kunyamula katundu wa axial, wokhala ndi ngodya yolumikizira ya 30°<τ≤90°. Malinga ndi ngodya zosiyanasiyana zolumikizirana, amatha kugawidwa m'magulu awa:

 

1) Ma bearing ozungulira a Axial contact thrust — ma bearing ozungulira okhala ndi ngodya yolumikizira ya nominal τ=90°. Oyenera kunyamula katundu wa axial mbali imodzi;

 

2) Ma bearing ozungulira olumikizana ndi ngodya — ma bearing olumikizana ndi ngodya yolumikizana ndi dzina la 30°<τ<90°. Abwino kwambiri pa katundu wozungulira wonyamula katundu, komanso amatha kunyamula katundu wophatikizana.

 

2.Maberani ozunguliraZigawidwa m'magulu malinga ndi kapangidwe ka mphete yakunja:

 

a) Chifaniziro cha mphete yakunja ya chidutswa chimodzi;

 

b) Chifaniziro cha mphete yakunja yogawanika kamodzi;

 

c) Chifaniziro cha mphete yakunja yozungulira yogawanika kawiri;

 

d) Chifaniziro cha mphete yakunja yokhala ndi zidutswa ziwiri.

 

3. Maberani ozunguliraZigawidwa m'magulu malinga ndi ngati zalumikizidwa kumapeto kwa ndodo:

 

a) (Zambiri) maberani ozungulira;

 

b) Mabearings ozungulira a ndodo, okhala ndi njira zingapo zogawa:

 

1) Malinga ndi ziwalo zomwe zimagwirizana ndi ndodo kumapeto:

 

— Chogwirira chozungulira cha ndodo chosonkhanitsidwa: chogwirira chozungulira cha ndodo chokhala ndi bore yozungulira, chokhala ndi chogwirira chozungulira chozungulira choyikidwa mu bore, chokhala ndi kapena chopanda bolt;

 

— Chogwirira chozungulira cha ndodo chimodzi: chogwirira chozungulira cha ndodo chokhala ndi chibowo chamkati chozungulira, chokhala ndi mphete yamkati yolumikizira yomwe yayikidwa mu chibowo, chokhala ndi kapena chopanda bolt;

 

— Bolt-head rod end bearing yozungulira: ndodo kumapeto yokhala ndi mpando wa mpira, momwe bolt-head imayikidwa.

 

2) Malinga ndi mawonekedwe a kulumikizana kwa shank kumapeto kwa ndodo:

 

— Chifaniziro chamkati cha ndodo ya ulusi: shank ya kumapeto kwa ndodo ndi ndodo yowongoka yokhala ndi ulusi wamkati;

 

— Chifaniziro cha ndodo yakunja yozungulira: tsinde la ndodo ndi ndodo yowongoka yokhala ndi ulusi wakunja;

 

— Chogwirira chozungulira cha kumapeto kwa ndodo chokhala ndi maziko olumikizidwa: shank ya kumapeto kwa ndodo ili ndi mpando wozungulira, mpando wa sikweya, kapena mpando wozungulira wokhala ndi mapini oikira, omwe amamangiriridwa kumapeto kwa ndodo mwa kuwotcherera;

 

— Chophimba chozungulira cha kumapeto kwa ndodo chokhala ndi mpando wotsekera: tsinde la kumapeto kwa ndodo lili ndi malo olumikizirana mkati mwake okhala ndi chipangizo chotsekera.

 

4. Ma bearing ozungulira amagawidwa m'magulu malinga ndi ngati amafunika kudzozedwanso ndi kukonzedwa panthawi yogwira ntchito:

 

a) Ma bearing ozungulira okonzedwa ndi mafuta;

 

b) Ma bearing ozungulira odzipangira okha mafuta osakonza.

 

5. Ma bearing ozungulira amagawidwa malinga ndi kuphatikiza kwa zipangizo zomwe zimagwiritsidwa ntchito pamalo otsetsereka:

 

a) Mabeya ozungulira achitsulo/chitsulo;

 

b) Ma bearing ozungulira achitsulo/mkuwa;

 

c) Zitsulo/PTFE zozungulira zozungulira;

 

d) Mabeya ozungulira a nsalu yachitsulo/PTFE;

 

e) Mabeya ozungulira achitsulo/pulasitiki olimbikitsidwa;

 

f) Ma bearing ozungulira a alloy okhala ndi chitsulo/zinc.

 

6. Ma bearing ozungulira amagawidwa m'magulu malinga ndi mayunitsi omwe amagwiritsidwa ntchito pa miyeso ndi kulekerera:

 

a) Maberani ozungulira a Metric;

 

b) Maberani ozungulira achifumu.

 

7. Ma bereki ozungulira amagawidwa m'magulu onse malinga ndi momwe katunduyo amayendera, ngodya yolumikizirana, ndi mtundu wa kapangidwe kake:

 

a) Maberani ozungulira a radial;

 

b) Mabeya ozungulira olumikizana ndi ngodya;

 

c) Maberani ozungulira opindika;

 

d)Maberani ozungulira a kumapeto kwa ndodo.

Ma bearing ozungulira amathanso kugawidwa m'mitundu yosiyanasiyana ya kapangidwe kake malinga ndi mawonekedwe ake (monga kukhalapo kapena kusakhalapo kwa zida zotsekera, kapangidwe ka ma grooves odzola ndi mabowo, kapangidwe ka ma grooves ogawa mafuta, kuchuluka kwa ma grooves osungira mphete, njira yozungulira ya ulusi wa kumapeto kwa ndodo, ndi zina zotero).
