Chii chinonzi mabheyaringi ekugadzira superfinishing?

Maitiro ekugadzira superfinishing haangoshandiswi muindasitiri yekutakura mabheyaringi chete, asiwo mumainjini, uye mimwe michina nematurusi akanyatsogadzirwa zvakatangawo kushandisa maitiro aya.

Chii chinonzi superprecision yebheya?

Kugadzira simbi yepamusoro inzira yekutsvedzerera iri kufamba kwekudya kuti uwane kukuya kudiki.

Pamusoro pechinhu chisati chagadzirwa zvakanaka chinowanzo tenderedzwa zvakanaka uye kukuyiwa. Zvikurukuru, zvinoreva nzira yekugadzirisa zvinhu zvakanaka isinganyanyi kumanikidzwa pachinhu chinoshandiswa pakugadzira nechinhu chinokwenya (dombo remafuta) pasi pemamiriro akanaka ekuzora uye ekutonhodza, uye inoita kufamba nekukurumidza uye kupfupi kwekudzokorora kwechinhu ichi chichifamba nekumhanya kwakati wandei munzira yekutenderera kwechinhu chakaoma.

Basa rekugadzira superfinishing nderei?

Mukugadzirwa kwema "rolling bearings", superfinishing ndiyo nzira yekupedzisira yekugadzirisa "bearing ring", iyo inoita basa rakakosha mukuderedza kana kubvisa kutsauka kwakatenderera kunosara ne "grinding processing", kugadzirisa chikanganiso chechimiro che "trench", kunatsa kuomarara kwayo pamusoro, kunatsiridza hunhu hwemuviri uye hwemakanika hwepamusoro, kuderedza kudedera uye ruzha rwe "bearing", uye kunatsiridza basa re "bearing".

Inogona kuverengerwa muzvikamu zvitatu zvinotevera

1. Zvinogona kuderedza kusimba kwemvura. Munguva yekupedzisa zvakanyanya, kuitira kuti dombo remafuta rigare richishanda pamusoro pemafungu uye risabatane nemudziyo, arc yedombo remafuta inosangana nechinhu chebasa ≥ kureba kwehurefu hwemvura pamusoro pechinhu chebasa, kuitira kuti kumanikidzwa kwechikamu chebasa kuve kukuru, uye peak yakakombama ibviswe, nokudaro ichideredza kusimba kwemvura.

2. Kuvandudza kukanganisa kwemugero wenzira yemujaho webhora. Kupedzisa zvakanyanya kunogona kuvandudza kukanganisa kwemugero weinenge 30% yenzira dzemujaho.

3. Inogona kukonzera kumanikidzwa pamusoro pechinhu chinokuya zvakanaka kwazvo. Munguva yekupedzisa, kukanganiswa kwepurasitiki inotonhora kunonyanya kugadzirwa, kuitira kuti mushure mekupedzisa, kumanikidzwa kwakasara kunoumbwa pamusoro pechinhu chinogadzirwa.

4. Inogona kuwedzera nzvimbo yekubata pamusoro pebasa referrule. Mushure mekupedzisa zvakanyanya, nzvimbo yekubata pamusoro pebasa referrule inogona kuwedzerwa kubva pa15% ~ 40% mushure mekukuya kusvika 80% ~ 95%.

Maitiro ekugadzira superfinishing:

1. Kucheka mabheyaringi

Kana pamusoro pedombo rekukuya panosangana nepamusoro penzvimbo yemujaho wakaoma, nekuda kwenzvimbo diki yekubata uye simba guru panzvimbo yeyuniti, pasi pekumanikidzwa kwakati, dombo rekukuya rinotanga raitwa "reverse cutting" yebearing workpiece, kuitira kuti chikamu chezvidimbu zvinogumbura pamusoro pedombo rekukuya chiwire chobva chapwanyika, zvichiratidza mamwe magirasi matsva akapinza uye mipendero yekucheka. Panguva imwe chete, bump yepamusoro pebearing workpiece inochekwa nekukurumidza, uye crest ne grinding decay layer pamusoro pebearing workpiece zvinobviswa nekucheka nekucheka. Danho iri rinonzi cutting phase, uye ndipo padanho iri apo simbi yakawanda inobviswa.

2. Kucheka hafu yemabheyaringi

Sezvo kugadzira kuchiri kuenderera mberi, pamusoro pechishandiso chebearing workpiece chinogadziriswa zvishoma nezvishoma. Panguva ino, nzvimbo yekubatana pakati pedombo rekukuya nepamusoro pechishandiso ichi inowedzera, kumanikidzwa kwenzvimbo imwe neimwe kunoderera, kudzika kwekucheka kunoderera, uye kugona kwekucheka kunoderera. Panguva imwe chete, maburi ari pamusoro pedombo rekukuya anovharika, uye dombo rekukuya riri muchimiro chekucheka zvishoma. Danho iri rinozivikanwa sechikamu chekucheka hafu chekupera kwebearing workpiece, umo mamaki ekucheka pamusoro pechishandiso chebearing anova akajeka uye ane rima.

3. Danho rekupedzisa

Danho iri rinogona kukamurwa kuita matanho maviri: rimwe danho rekuchinja kwekukuya; rechipiri danho rekukuya mushure mekumira kucheka

Danho rekuchinja kwekukuya:

Tsanga inokwenya inorodzwa yoga, mupendero wetsanga inokwenya unotsvedzerera, chip oxide inotanga kuiswa mugomba redombo remafuta, upfu hunokwenya hunovhara maburi ematombo emafuta, kuitira kuti tsanga inokwenya igone kuchekwa zvisina simba, pamwe chete nekubuda nekukuya, ipapo kuomarara kwenzvimbo yebasa kunodzikira nekukurumidza, uye pamusoro pedombo remafuta panobatanidzwa neblack chip oxide.

Mira chikamu chekukuya chekucheka:

Kukweshana kwematombo emafuta nemidziyo yebasa kwave kwakatsetseka, nzvimbo yekubata yakawedzera zvakanyanya, kumanikidzwa kunoderera, tsanga yeabrasive yakakwanisa kupinda mufirimu remafuta nekubata nemidziyo yebasa, kana kumanikidzwa kwefirimu remafuta pamusoro pebheyaringi kwakaenzana nekumanikidzwa kwedombo remafuta, dombo remafuta rinoyangarara. Panguva yekuumbwa kwefirimu remafuta, hapana mhedzisiro yekucheka. Danho iri rakasiyana ne superfinishing.
