Bearing superfinishing bụ usoro na-eji ire ụtọ bụ mmegharị nri iji nweta obere-egweri.
A na-atụgharị elu tupu emechaa ya nke ọma na ala.

Gịnị bụ ọrụ nke ibu superfinishing?
N'ime usoro mmepụta nke rolling bearings, superfinishing bụ usoro ikpeazụ nke ịmepụta mgbanaka mgbanaka, nke na-arụ ọrụ dị mkpa n'ibelata ma ọ bụ wepụ ihe mgbanaka okirikiri nke fọdụrụ site na-egweri nhazi, na-edozi njehie udi nke trenchi, na-emeziwanye ọdịdị elu ya, na-eme ka ọkpụkpụ ahụ dịkwuo mma. Njirimara anụ ahụ na nke igwe nke elu, na-ebelata mkpọtụ na mkpọtụ nke ihe ahụ, na imeziwanye ozi nke ibu ahụ.
Enwere ike itinye ya n'akụkụ atọ ndị a
1. Ọ nwere ike belata waviness nke ọma. Na usoro nke ibu-emecha, iji hụ na nkume mmanụ mgbe niile na-eme ihe na crest nke ebili mmiri na ọ dịghị kọntaktị na trough, arc nke mmanụ nkume na kọntaktị na workpiece.≥ogologo wavelength nke waviness n'elu nke workpiece, nke mere na kọntaktị kọntaktị nke crest bụ ibu, na convex elu na-ewepụ, si otú ibelata waviness.
2. Melite njehie groove nke ụzọ ịgba bọọlụ na-ebu. Ịmecha nke ọma nwere ike melite njehie groove nke ihe dịka 30% nke ụzọ ọsọ ọsọ.
3. Ọ nwere ike ịmepụta nrụgide nrụgide n'elu nke oke-egweri dị mma. Na usoro nke superfinishing, oyi plastic deformation bụ tumadi eme, nke mere na mgbe superfinishing, mpụta mkpakọ nrụgide na-etolite n'elu nke workpiece.
4. Ọ nwere ike ịbawanye mpaghara kọntaktị nke elu ọrụ nke ferrule. Mgbe emechara nke ọma, enwere ike ịbawanye mpaghara kọntaktị nke elu ọrụ nke ferrule site na 15% ~ 40% mgbe egwerichara ruo 80% ~ 95%.
Usoro mmecha nke imecha:
1. Ịcha nke bearings
Mgbe elu nke nkume egweri na-ejikọta ọnụ na convex elu nke oke ọsọ ọsọ ọsọ, n'ihi obere kọntaktị na ike dị ukwuu na mpaghara unit ahụ, n'okpuru ọrụ nke nrụgide ụfọdụ, a na-ebu ụzọ tinye nkume na-egweri. na "reverse ọnwụ" edinam nke amị workpiece, nke mere na akụkụ nke abrasive ahụ n'elu nke egweri nkume dapụ na iberibe, na-ekpughe ụfọdụ ọhụrụ nkọ abrasive grains na ịcha n'ọnụ. N'otu oge ahụ, a na-egbutu elu elu nke ihe na-arụ ọrụ na-arụ ọrụ ngwa ngwa, na crest na-egweri emebi oyi akwa n'elu nke bearing workpiece na-ewepụ site n'ịcha na laa azụ ịkpụ. A na-akpọ ọkwa a oge ịkpụ, ọ bụkwa n'oge a ka a na-ewepụ ihe ka ukwuu n'ụgwọ ọla.
2. Ọkara-ịcha nke bearings
Ka machining na-aga n'ihu, a na-eji nwayọọ nwayọọ na-eji nwayọọ nwayọọ na-eme ka elu nke ọrụ ahụ na-arụ ọrụ. N'oge a, ebe kọntaktị dị n'etiti nkume egweri na elu nke workpiece na-abawanye, nrụgide kwa otu mpaghara na-ebelata, omimi nke ịkpụ na-ebelata, na ike ịkpụ na-ebelata. N'otu oge ahụ, a na-egbochi pores ndị dị n'elu nkume egweri, nkume na-egweri na-adịkwa n'ụdị nke ọkara. A na-akpọ ọkwa a dị ka ọkara nke ịkpụcha agbacha agbacha agbacha, nke akara ncha n'elu ihe arụrụ arụ ahụ na-adịwanye ọkụ ma nwee onwunwu gbara ọchịchịrị.
3. Ogbo imecha
Enwere ike kewaa ogbo a ụzọ abụọ: otu bụ usoro ntugharị igwe, na nke ọzọ bụ ogbo egweri mgbe a kwụsịrị ịkpụcha ya.
Oge ngbanwe nke igwe:
Mkpụrụ ọka abrasive na-eme onwe ya, ọnụ ọnụ nke ọka na-eme ka ọ dị mma, oxide mgbawa na-amalite ịbanye n'ime oghere nke nkume mmanụ, ntụ ntụ na-egbochi oghere nkume mmanụ, nke mere na a ga-egbutu ọka ahụ naanị. na-adịghị ike, na-esonyere extrusion na egweri, mgbe ahụ n'elu roughness nke workpiece na-ngwa ngwa belata, na elu nke mmanụ nkume na-ejikọta na nwa mgbawa oxide.
Kwụsị oge ịcha ọka:
Nkume mmanụ na workpiece esemokwu na onye ọ bụla ọzọ ndidi nnọọ ire ụtọ, kọntaktị ebe na-ukwuu ụba, nrụgide tụlee, na abrasive ọka enwewo ike banye n'ime mmanụ ihe nkiri na kọntaktị na workpiece, mgbe mmanụ film mgbali nke ibu elu. na-edozi ya na nrụgide nkume mmanụ, nkume mmanụ na-ese n'elu mmiri. N'oge e guzobere ihe nkiri mmanụ, ọ dịghị mmetụta ịkpụ. Oge a pụrụ iche maka imecha ihe.
