Ụdị na nhazi nke Bearings Gburugburu

 

1. Bearing gburugburuA na-ekewa ha dịka ntụziaka nke ibu ha nwere ike ibu ma ọ bụ akụkụ kọntaktị aha:

 

a) Bearing radial — a na-ejikarị ebu ibu radial, nwere akụkụ kọntaktị aha nke 0°≤τ≤30°. Dịka akụkụ kọntaktị aha dị iche iche si dị, enwere ike kewaa ha ọzọ n'ime:

 

1) Bearing gburugburu nke nwere njikọ radial — bearing nwere akụkụ kọntaktị aha τ=0°. Dabara adaba maka ibu ibu radial ma nwee ike ibu obere ibu axial n'akụkụ ọ bụla;

 

2) Mbibi gburugburu radial kọntaktị angular— bearings nwere akụkụ kọntaktị aha 0°<τ≤30°. Dabara adaba maka ibu ejikọtara ọnụ yana akụkụ radial na axial.

 

b) Bearings nke a na-akpọ thrust — a na-ejikarị ebu ibu axial, nwere akụkụ kọntaktị aha nke 30°<τ≤90°. Dịka akụkụ kọntaktị aha dị iche iche si dị, enwere ike kewaa ha ọzọ n'ime:

 

1) Mbido gburugburu nke njikọ aka axial — mbido nke njikọ aka a na-akpọ τ=90°. Dabara adaba maka ibu ibu axial n'otu ụzọ;

 

2) Bearing gburugburu nke nwere ike ịpịa akụkụ — bearing ndị nwere akụkụ kọntaktị aha 30°<τ<90°. Ọ dabara nke ọma maka ibu ibu axial, mana ọ nwekwara ike ibu ibu ndị ejikọtara ọnụ.

 

2.Bearing gburugburuA na-ekewa ha dịka nhazi nke mgbanaka mpụta si dị:

 

a) Mgbaaka mpụta nke nwere otu akụkụ nke nwere ihe gburugburu;

 

b) Mgbaaka mpụta nke nwere otu akụkụ nke nwere gburugburu;

 

c) Mgbaaka mpụta nke gbara okirikiri nke kewara abụọ;

 

d) Mgbaaka mpụta nke nwere akụkụ abụọ nke nwere gburugburu.

 

3. Bearing gburugburua na-ekewa ha dịka ma ha ejikọtara na nsọtụ mkpanaka:

 

a) (Izugbe) ihe ndị na-agba gburugburu;

 

b) Mbibi gburugburu nke mkpanaka, nke nwere ọtụtụ usoro nhazi:

 

1) Dịka akụkụ ndị na-ejikọ na njedebe mkpanaka si dị:

 

— Mkpọchi mkpanaka gburugburu: njedebe mkpanaka nwere oghere silinda, nke nwere ihe mkpuchi okirikiri radial arụnyere na oghere ahụ, yana ma ọ bụ na-enweghị ihe mkpuchi;

 

— Mbido gburugburu nke otu akụkụ nke mkpanaka: njedebe nke mkpanaka nwere oghere dị n'ime okirikiri, nke etinyere mgbanaka dị n'ime nke mgbaaka ahụ n'ime oghere ahụ, ya na ma ọ bụ na-enweghị bọtịnụ;

 

— N'elu ogwe bọọlụ nke nwere isi bọọlụ nke nwere ihe mkpuchi gburugburu: n'elu ogwe bọọlụ nke nwere oche bọọlụ, nke a na-etinye ihe mkpuchi isi bọọlụ.

 

2) Dịka njirimara njikọ nke ogwe aka njedebe mkpanaka si dị:

 

— Mkpọchi eriri dị n'ime nke nwere ihe dị okirikiri: mkpọchi ogwe bụ mkpanaka kwụ ọtọ nke nwere ihe dị n'ime;

 

— Mpụta eriri mkpanaka gburugburu: ogwe mkpanaka bụ mkpanaka kwụ ọtọ nwere eriri mpụga;

 

— Mkpọchi gburugburu nke mkpanaka nwere ntọala welded: ogwe aka mkpanaka nwere oche flange, oche square, ma ọ bụ oche cylindrical nwere ntụtụ nhazi, nke a na-etinye na nsọtụ mkpanaka site na ịgbado ọkụ;

 

— Ogwe mkpanaka nwere oche mkpọchi: ogwe mkpanaka nwere oghere eriri dị n'ime ya nwere ngwaọrụ mkpọchi.

 

4. A na-ekewa ihe ndị na-agba gburugburu dịka ma ha chọrọ ka e tinyeghachi mmanụ na mmezi n'oge ọrụ:

 

a) Bearings gburugburu nke e ji mmanụ rụọ ọrụ;

 

b) Bearings gburugburu na-enye onwe ha mmanụ n'enweghị mmezi.

 

5. A na-ekewa ihe ndị e ji agba gburugburu dịka njikọta nke ihe eji eme ihe maka elu ndị na-amị amị:

 

a) Ihe ndị e ji ígwè/ígwè mee gburugburu;

 

b) Ihe ndị e ji ígwè/ọla kọpa mee na-agba gburugburu;

 

c) Ihe mejupụtara ígwè/PTFE nke nwere gburugburu;

 

d) Ákwà ígwè/PTFE nke nwere ihe ndị dị gburugburu;

 

e) Ihe ndị e ji ígwè/plastic mee ka ha sie ike;

 

f) Ihe ndị e ji ígwè/zinc mee nke nwere okirikiri alloy.

 

6. A na-ekewa ihe ndị na-agba gburugburu dịka nkeji eji maka nha na nguzogide si dị:

 

a) Metric roundbearings;

 

b) Ihe ndị e ji agba gburugburu nke alaeze ukwu.

 

7. A na-ekewa ihe ndị na-agba gburugburu nke ọma dịka ntụziaka nke ibu, akụkụ kọntaktị aha, na ụdị nhazi si dị:

 

a) Ihe ndị na-agba gburugburu radial;

 

b) Mbibi gburugburu nke nwere njikọ aka;

 

c) Ịkwanye ihe ndị na-agba gburugburu;

 

d)Mbido gburugburu nke mkpanaka.

Enwere ike kewaa ihe ndị na-agba gburugburu n'ụdị nhazi dị iche iche dịka ọdịdị nhazi ha si dị (dịka ọmụmaatụ, ọnụnọ ma ọ bụ enweghị ngwaọrụ mkpuchi, nhazi nke oghere mmanụ na oghere, nhazi nke oghere nkesa mmanụ, ọnụọgụ nke oghere mgbanaka na-ejide, ntụziaka ntụgharị nke eriri njedebe mkpanaka, wdg).
