Ukusila okungenaziko

Ukusila okungenaziko:

Umatshini wokusila ongenaziko ngumatshini oqhelekileyo wokusila, owaziwa ngokuba ngumatshini wokusila oyicylindrical. Ukusetyenziswa kwayo okuphambili kumashishini okuvelisa izixhobo zomatshini, ezisetyenziselwa ukusetyenzwa kweentlobo ezahlukeneyo zeendawo ezincinci ze-batch shaft, kubandakanywa nejenali, i-chain shaft, ukupompa ukulungiswa, njl.

Iimpawu zokusila zegrinder engenaziko:

Umatshini wokusila ongenaziko unokufikelela kwi-rough surface ephantsi, ngokuqhelekileyo unokufikelela ukuchaneka kwe-dimensional ye-T6 ~ IT, kwaye ubuninzi obufunyenweyo obufunyenweyo yi-Ra125 ~ 0Oum; Uburhabaxa bomphezulu wokusila ngokugqithisileyo kunye nokusila kwesibuko kunokufikelela kwiRa0.05um.

I-2, umatshini wokusila ongenaziko unokugaya zonke iintlobo zetsimbi ezicinyiweyo, insimbi eshushu ye-alloy kunye ne-alloy enzima kunye nezinye izinto ezinzima.

I-3, umatshini wokugaya i-cylindrical ongenaziko wokwenza inkqubo. Ngenxa yokuba ivili lokugaya linokucutshungulwa kwiimilo ezahlukeneyo ngokweemfuno ze-machining, kuyimfuneko ukugaya imilo eyinkimbinkimbi ngokufutshane. Isetyenziswe ngokubanzi kwifom yokugaya ukunciphisa inkqubo ephakathi.

I-4, i-centerless grinder grinder margin incinci kakhulu, ifanelekile ukuphosa, i-fa forging, i-stamping iinxalenye zenkqubo yokulandelelana, ukwenzela ukuba kuphuculwe ngakumbi ukuchaneka kweendawo ezingenanto, ukunciphisa uburhabaxa bomhlaba.

I-5, umatshini wokugaya ongenaziko ufanelekile kwizixhobo ezizenzekelayo, unokwandisa inkqubo yokugaya.

Okokuqala, amandla okugaya

①. Umthombo kunye nokubola kwamandla okugaya

Kukho amandla alinganayo kunye achaseneyo asebenza kwivili lokugaya kunye nomsebenzi ngexesha lokugaya. Amandla avela kwinkqubo yokusila abizwa ngokuba yi-grinding force (amandla okusika). Amandla okugaya ngokuyinhloko aqulethwe ngamacandelo amabini: ingqolowa enqabileyo iya kubangela ukuba i-deformation enkulu yeplastiki yentsimbi inqunywe xa kunqunyulwa isinyithi, kwaye amandla okusika akhiwe; Amandla okugaya awenziwe phakathi kwe-particle kunye ne-workpiece surface ngexesha lokusika.

(2) Impembelelo yokusila amandla kumatshini

Ekusikeni, iinqununu zokugaya zinqunywe nge-Angle yangaphambili engalunganga, kwaye i-fillet radius R yomgca wokusika idla ngokuba nkulu kunomlinganiselo wokusika ngasemva, ngoko ke ukunyanzeliswa kwe-radial yokucinezela amaqhekeza okugaya kwi-workpiece inkulu, ngokubanzi Fp = ( 2 ~ 3)FC. Ngenxa yamandla amakhulu e-radial, inkqubo yenkqubo eyenziwe ngesixhobo somatshini, i-workpiece kunye nevili lokugaya ivelisa i-deformation enkulu ye-elastic, echaphazela ukuchaneka kokusila. Ukuba i-workpiece ikhubazekile ngenxa yesenzo samandla e-radial kunye ne-tangential force, intshukumo ehambelanayo ye-axis yayo ngu-e, eya kubangela impazamo yobubanzi bomsebenzi.

Ukuguqulwa kwenkqubo yenkqubo okubangelwa ngamandla eradial kaninzi kwenza elona xabiso lichanekileyo lokusikwa ngasemva lahluke kwixabiso lomthi eliboniswe kwisixhobo sokucofa sevili. Ke ngoko, umjikelo ofanelekileyo wokusila kukuyeka emva kokutya ukuphelisa i-deformation ebangelwa yi-radial forces. Olu hlobo lokugaya ngaphandle kwesondlo lubizwa ngokuba yi-light grinding okanye ukugaya okungenakukhanya. Xa kusila i-shaft ebhityileyo, i-workpiece igubulwa kwimilo yegubu ngama-radial forces. Iimpawu zevili lokusila, ububanzi bokugaya ivili lokusila, izinto zokusebenza, isixa sokusila (ap, f) sinempembelelo enkulu kumandla ombane.

Yintoni esifanele sinikele ingqalelo kuyo xa umatshini wokupolisha wetyhubhu engqukuva yentsimbi engenasici?
