Nhazi nke ObereBịagharị Roller

Mbido obere nke nwere mgbanaka mpụta abụọ yiri nke ahụ, mgbanaka dị n'ime, ihe mkpuchi, na ihe mkpuchi dị n'ime. A na-eji skru jikọọ ọkara mgbanaka mpụta abụọ ahụ, a na-ekekwa ihe mkpuchi ahụ n'ime akpa igbe. N'ihi na a na-ahazi ihe mkpuchi dị n'akụkụ n'ụdị obe, obere ihe mkpuchi nwere ike iguzogide ibu axial, ibu radial, na oge ntụgharị. N'oge ọrụ, a na-edozi mgbanaka mpụta, mgbanaka dị n'ime na-agbagharịkwa.

1) Ọkụ esemokwu nke oberebearing roller gaferena-abawanye ka ọsọ ntụgharị na-abawanye na oge ntụgharị. Na ngwa ntụgharị nke enwere ike ịgbanwe oge, a ga-edozi ọnọdụ ọrụ nke ọma iji belata ihe egwu nke mmụba nke ike mgbagha nke bearing.

 

2) Maka otu radial clearance ahụ, oge ntụgharị buru ibu na-eme ka torque breaking torque buru ibu. Ka radial clearance na-abawanye, torque breaking torque na-ebelata, mana ọ na-eme ka ọ kwụsie ike mgbe radial clearance gafere 5 μm. N'ịtụle nkwụsi ike ọrụ, a na-atụ aro ka ijikwa radial clearance n'etiti 5 na 10 μm.

 

3) Ka uru zuru oke nke nkuku ụzọ ịgba ọsọ buru ibu, otú ahụ ka mmetụta ibu dị n'etiti na-apụta ìhè na ntụziaka generatrix roller, na-eduga na nkesa nrụgide na-adịghị nhata na nkuku ụzọ ịgba ọsọ buru ibu. A na-atụ aro ka chịkwaa nkuku ụzọ ịgba ọsọ dị n'ime n'ime ±2′ na nkuku ụzọ ịgba ọsọ dị n'èzí n'ime ±1′ iji belata nkuku ụzọ ịgba ọsọ.

 

4) Mpịakọta ndị e ji Logarithm gbanwee na-enye obere ike esemokwu n'elu ọtụtụ oge ntụgharị. Agbanyeghị, mgbe oge ntụgharị na-eru nso 400 N·m, ọdịiche dị n'etiti mpịakọta ndị e ji logarithm gbanwee na mpịakọta ndị e ji logarithm gbanwee n'ibelata ike ntụgharị nke bearing adịghị mkpa. Iji belata ike ntụgharị, a na-atụ aro mpịakọta ndị e ji logarithm gbanwee n'ime imewe bearing.

 

5) Mmetụta nke paramita nhazi nkebearing roller gaferena ike ọkụ, site na nke kacha ukwuu ruo nke kacha nta, bụ dịka ndị a: radial clearance, inner raceway angle difference, inner raceway angle difference, upper mpụta ring raceway difference, na ala mpụta ring raceway difference. Ya mere, a ga-ebu ụzọ chịkwaa radial clearance nke crossed roller bearings, sochiri ya na crossavement angle raceway, karịsịa inner raceway difference, iji melite arụmọrụ strike torque nke bear.
