Inqubo yokuzungezisa yeindingiliziukunithaumshiniumnyakazo ngokuyinhloko ohlanganisa ukunyakaza okuyisiyingi okuzungeza i-eksisi emaphakathi, okunezingxenye eziningi ezifakwayo futhi ezisebenza endaweni efanayo. Ngemva kwesikhathi esithile sokusebenza emshinini wokuluka, umshini udinga ukulungiswa okuphelele. Umsebenzi oyinhloko phakathi nale nqubo awuhlanganisi nje kuphela ukuhlanza imishini kodwa nokufaka esikhundleni sanoma yiziphi izingxenye ezilimele. Okugxilwe kakhulu ekuhloleni ukunemba kokufaka nokunemba kokusebenza kwengxenye ngayinye ukuze kunqunywe ukuthi kube khona yini izinguquko noma ukuchezuka okungaphezu kwebanga lokubekezelela elishiwo. Uma kunjalo, kufanele kuthathwe izinyathelo zokulungisa.
Ukuhlaziywa kwethulwa ngezimbangela eziholela ekuhlulekeni ekufinyeleleni ibanga elidingekayo lokuzungeza kanye nokucaba ezingxenyeni ezifana namasirinji namapuleti.
Ukuzungezisa kwe-pulley kwehlulekile ukuhlangabezana nokunemba okudingekayo.
Isibonelo, ukuguga kwemigqa yokubeka phakathi kwe-ipuletikanye ne-pulley (evame kakhulu kumodi yokuslayida ekhungathekayo), okungaholela ekuxegisweni noma ukuguga kwethrekhi yomhlahlandlela wezintambo noma umkhono ophakathi nendawo ngaphakathi kwesitsha esikhulu somshini esinezinhlangothi ezimbili, konke kungaholela ekungakwazini ukufeza ukunemba okudingekayo ukujikeleza kwesilinda. Indlela yokuhlola imi kanje: beka umshini endaweni yokuma, beka isikhombisi segeji yokudayela endaweni yesibambi senaliti esinamazinyo (uma izikulufu ezivikela inaliti noma idiski kusiphathi senaliti esinamazinyo noma isigubhu senaliti singakashayi. ithukululiwe, i-pointer ingabuye ibekwe endaweni yesilinda yenaliti noma i-disc), nesihlalo segeji yokudayela.i-adsorptionemshinini ongaphenduki ngediski elinamazinyo noma isigubhu senaliti, njengesitsha esikhulu noma ibhodwe, njengoba kuboniswe kuMfanekiso 1 kanye noMfanekiso 2. Ngokukhohlisa ngamandla ithreyi ye-chuck noma ye-pin plate, qaphela ushintsho lokudayela. ibanga lesikhombi segeji. Uma iwela ngaphansi kuka-0.001 mm, ikhombisa ukuthi ukunemba kokusebenza kwe-chuck kuhle kakhulu. Uma isukela phakathi kuka-0.01 mm no-0.03 mm, ukunemba kuhle; uma idlula u-0.03 mm kodwa ingaphansi kuka-0.05 mm, ukunemba kuyisilinganiso; futhi uma idlula u-0.05 mm, ukunemba kokusebenza kwe-chuck kuba kuncane kakhulu. Kuleli qophelo, ukulungisa ukuzungeza kwepuleti lephinikhodi libe phakathi kuka-0.05 mm kuzoba nzima kakhulu noma kungenzeki, okudinga ukubuyiselwa kokunemba kokusebenza kwe-chuck noma ithreyi kuqala. Indlela yokubuyisela ukunemba ekusebenzeni izohluka kuye ngezakhiwo ezihlukene nezindlela zokuzungezisa kwe-pulley, okungaphezu kobubanzi balesi sihloko.
Lapho ukuxhumana kuvela phakathi kwama-cogs ayishumi nambili nepistoni-cylindricalazilingani noma lapho indawo yokuthintana phakathi kwepuleti lephini kanye nesisekelo ingalingani, lapho kusetshenziswa ucingo oluyindilinga olucindezelayo, izikhala phakathi kwepistoni-cylindrical, i-pin plate, i-disc, kanye nesisekelo kuzocindezelwa ndawonye ngamandla, kubangele ipistoni-cylindricalkanye nepuleti lephini ukuze libe ne-elastic deformation. Ngenxa yalokho, i-roundness izophambuka ekubekezeleleni okudingekayo. Ngokwezimo ezingokoqobo, lapho izikulufu ezibambile zixegiswa kancane, ukuzungeza kwe-chuck ne-spindle kungalungiswa kalula kube ngaphakathi kuka-0.05mm, kodwa lapho uhlola ukujikeleza futhi ngemva kokukhiya izikulufu, kudlula ububanzi obudingekayo obungaphansi kuka-0.05mm imajini ebalulekile. Izinyathelo zokubhekana nalolu daba zimi kanje
Nethezeka izikulufu eziqinisiwe, lungisa isirinji nepuleti yenaliti cishe libe yindilinga, uqinisekise ukuthi lingaphansi kuka-0.03 mm ububanzi. Dedela ikhanda legeji, beka ikhanda legeji kurimu noma ngaphezulu kwentamo yesilinda, noma ipuleti yenaliti, zungezisa isikulufu sokuvikela ngasinye kuze kube yilapho iphoyinti legeji likhomba phansi, vikela izikulufu, bheka ushintsho enalithi yegeji, uma ukufunda kuncipha, kukhombisa ukuthi kukhona isikhashana phakathi kwesilinda, ipuleti yenaliti, isondo legiya noma isisekelo.
Njengoba isikhombisi esikugeyiji sishintsha, faka izikhala eziwugqinsi ezifanele phakathi kwezikulufu eziqinisayo nhlangothi zombili, ukhiye izikulufu futhi, bese ubheka ushintsho lwesikhombi size silungiselwe ushintsho olungaphansi kuka-0.01 mm ngemva kokukhiya izikulufu. Ngokufanelekile, akufanele kube khona ushintsho nhlobo. Qhubeka uqinisa isikulufu esilandelayo ngendlela elandelanayo, uphinda inqubo kuze kube yilapho ibhawodi lokubopha ngalinye libonisa ushintsho esikhombini esingaphansi kuka-0.01 mm ngemva kokuqiniswa. Lokhu kuqinisekisa ukuthi alikho igebe phakathi kwesirinji, ipuleti yenaliti, kanye negiya noma isisekelo sokusekela lapho izikulufu ziqiniswa khona. Kuyaphawuleka ukuthi ngemva kokulungiswa kwesikulufu ngasinye, ngaphambi kokudlulela kusikulufu esilandelayo, kufanele sithukululwe ukuze kuqinisekiswe ukuthi isirinji nepuleti yenaliti kuhlala kusesimweni sokukhululeka kuyo yonke inqubo yokulungisa. Hlola ukuba flat kwesirinji nepleyiti yenaliti; uma isikhombisi sishintsha ngaphezu kuka-0.05 mm, faka amashimu ukuze usilungise sibe ngaphakathi kuka-±0.05 mm.
Khulula ikhanda lokuzithepha ngokwakho bese ulibeka eceleni kwesirinji noma unqenqema lwe-chuck. Lungisa ukushintsha kwesiyingi sepuleti lesisirinji ngokungekho ngaphezu kuka-0.05 mm bese uvala izikulufu.
Ukunemba kwe-usinki,ikhamerai-base plate noma i-shuttle frame ayikwazi ukuhlangabezana namazinga. Uhlobo olunjalo lwengxenye yomshini ngokuvamile luyinkampani yenethiwekhiikhameraisisekelo, izidingo zayo zokuthi flat kanye ne-engeli yokubuya aziphakeme njengalezo zepuleti yenaliti noma i-inaliti cylinder. Kodwa-ke, ngenxa yokulungiswa kwazo ngesikhathi sokukhiqiza ekuphenduleni izinguquko emkhiqizweni, zizolungisa phezulu naphansi noma kwesokunxele nakwesokudla, kunokuba zifane nepuleti yenaliti noma isilinda senaliti, esingalungiswa kanye bese sihlala singashintshiwe ngaphandle kokuthi kushintshwe. Ngakho-ke, ngesikhathi sokulungiswa, ukufakwa nokulungisa la mabhulokhi kubaluleka. Ngezansi, sizokwethula indlela ethile ngesibonelo Sebhodi Lokubulala Ukuphila, 2.1 Ukulungisa Ibhalansi.
Uma ileveli yethreyi iphelelwe amandla, qala ngokukhulula izikulufu namabhulokhi okubeka ethreyini.rama-acks, nezikali ze-adsorption ezihlezi kumasirinji,beka ikhanda lesikhombi onqenqemeni lwethreyi, zungezisa umshini uye kuthreyi ethile, futhi uvikele amabhawodi abophela ithreyi.i-crame. Bheka izinguquko ku-pointer. Uma kukhona noma yiluphi ushintsho, lubonisa ukuthi kunegebe phakathi kwebakaki nethreyi, okudinga ukusetshenziswa kwamashimu ukuze kuvikelwe. Lapho isikulufu sokukhiya siqiniswa, ukuhluka kwesilinganiso kungu-0.01 mm kuphela, kodwa kuphawuleka ikakhulukazi ukuthi ngenxa yendawo enkulu yokuxhumana phakathi kukabakaki nethreyi, kanye neqiniso lokuthi isiqondiso sesikhombi asihambisani nokufana. i-radius njengekhanda letafula, lapho isikulufu sokukhiya siqiniswa, nakuba kukhona igebe, ukuguqulwa kokufunda kwesikhombisi kungase kungabi njalo ukuncipha, kodwa kungase futhi kube ukwanda. Usayizi wokunyakaza kwesikhombi ubonisa ngokuqondile indawo yegebe phakathi kukabakaki nethreyi, njengoba kuboniswe kumfanekiso 3a, lapho igeji yokudayela ingase ifunde inani elikhulu lesikulufu sokukhiya. Uma unyawo lusesimweni esivezwe kuMfanekiso 3b, ukufundwa kwe-tachometer yesikulufu sokukhiya kuzokwehla. Ngokubona ukuhluka kokufundwayo, umuntu angakwazi ukunquma indawo yegebe futhi asebenzise izinyathelo ezifanele ngokufanele.
Ukulungiswa kokuyindilinga nokucaba kweijezi eliphindwe kabiliumshini
Lapho ububanzi kanye flatness of theijezi eliphindwe kabiliumshinikudlule ububanzi obujwayelekile, ukulungiswa kufanele kuqala kwenziwe ukuze kuqinisekiswe ukuthi ama-bearings nama-pulleys ngaphakathi kwesilinda esiyinhloko awakhululeki noma abe nokuxega phakathi kwemingcele eyamukelekayo. Uma lokhu sekuqinisekisiwe, ukulungiswa kungaqhubeka ngokufanele. Ngokuvumelana nezinga
Faka iyunithi ezimele ngokwemiyalo enikeziwe, bese ukhulula wonke amabhawudi amakhulu ayivikelayo. Idlulisela ipuleti le-pivot onyaweni olumaphakathi lokusekela, qinisa isikulufu ngasinye ngokuvikelekile, bheka ushintsho kugeji yokudayela ukuze uthole ukuthi ingabe likhona yini igebe phakathi konyawo losekelo olumaphakathi ne-tripod enkulu, futhi uma kunjalo, indawo yalo enembile. Umgomo uyafana nalowo osetshenziswa ekuhlaziyeni ushintsho ekufundeni kokudayela lapho kulungiswa izinga lethreyi, lapho izikhala zigcwaliswa ngama-spacers. Ngemva kokulungiswa ngakunye kwendawo yesikulufu, khulula lesi sikulufu ngaphambi kokuqhubeka nokulungiswa kwesikulufu esilandelayo kuze kube yilapho ukuqiniswa kwesikulufu ngasinye kubangela ushintsho ekufundeni kwewashi okungaphansi kwamamilimitha angu-0.01. Ngemva kokuqeda lo msebenzi, zungezisa umshini wonke ukuze uhlole ukuthi izinga lingaphakathi kwemingcele evamile. Uma idlula ububanzi obujwayelekile, lungisa ngamashimu.
Ngemuva kokulungiswa kokugxila, i-micrometer izofakwa njengemfuneko ngayinye. Ihlola ukujikeleza komshini ukuze kutholwe ukuthi ingabe iwela ngaphandle kwemingcele evamile, ukulungiswa kungenziwa ngezikulufo zokulungisa zomshini ukuze uwubuyisele phakathi kwebanga. Kubalulekile ukunaka ukusetshenziswa kwezikulufu, njengoba nje kusetshenziswa amabhlogo okuthola ithreyi. Akufanele umuntu asunduze ngamandla umkhono ophakathi nendawo ngokusebenzisa izikulufu, njengoba lokhu kungabangela ukuguga okunwebekayo kwemishini. Esikhundleni salokho, sebenzisa izikulufu zokulungisa ukuze uhambise umkhono omaphakathi endaweni yawo oyifunayo, bese ukhulula izikulufu futhi ufunde ukulinganisa kugeji. Ngemva kokulungiswa, izikulufu zokukhiya kufanele futhi zinamathele kumkhono ophakathi nendawo, kodwa akukho mandla okufanele asetshenziswe kuwo. Kafushane, akukho ukucindezeleka kwangaphakathi okufanele kwenziwe ngemva kokuqedwa kokulungiswa.
Ekulungiseni ukujula kwe-concentricity, kuyenzeka futhi nokukhetha amaphuzu ayisithupha e-diagonal njengamaphoyinti ereferensi, ngoba eminye imishini ikhombisa ukunyakaza kwe-eccentric ngenxa yokuguga, okwenza ama-trajectories awo afane ne-ellipse kunokuba umbuthano ophelele. Inqobo nje uma umehluko wokufundwayo othathwe nge-diagonally uwela ngaphakathi kwebanga elamukelekayo, kungathathwa njengokuhlangabezana nezinga. Kodwa lapho umphetho uhlanekezelwe ngenxa ye-ipuleti's deformation, okwenza indlela yayo yokunyakaza ifane ne-ellipse, kufanele kuqala ibe neipuleti'sibunjwe kabusha ukuze iqede ukuhlanekezela, ngaleyo ndlela ibuyisele indlela yokunyakaza yerimu esimweni esiyindilinga. Ngokufanayo, ukuchezuka okungazelelwe kokujwayelekile endaweni ethile nakho kungachazwa njengomphumela wokuguga noma ukuguqulwa kwe-pulley. Uma kwenzeka ngenxa deformation of theipuleti's, ukuguqulwa kufanele kuqedwe; uma kungenxa yokuguga, kuzodinga ukulungiswa noma ukushintshwa kuye ngobunzima.
