Kukwenya uye kukuya kwegwara rinotakura gwenzi uye thrust gwenzi rediki hydraulic turbine inzira yakakosha mukumisikidza uye kugadzirisa kwechiteshi chidiki chehydropower.
Mazhinji emabearings ediki akatwasuka hydraulic turbines haana spherical chimiro uye thrust pads haana anti huremu mabhaudhi. Sezvinoratidzwa mumufananidzo: A is aspheric structure; B haisi anti huremu bhaudhi, uye iyo yekusundira padhi inodzvanywa yakananga padhidhi. Izvi zvinotevera zvinonyanya kutaura nezve nzira, matanho uye zvinodiwa zvekukwenya uye kuiswa kweiyi fomu yemaitiro.
1. Zvishandiso zvekugadzirira ndeye katatu uye kaviri-sided oilstone. Hurefu hwekudzokera shure hunogona kugadziriswa maererano nemaitiro ako pachako. Kazhinji, zvakakodzera kushandisa 6-8 o'clock. Iyo yekare triangular kudzoserwa kumashure inogona zvakare kugadziridzwa. Kana zvichibvira, iwe unogona zvakare kushandisa chitubu simbi kurova rimwe kana maviri banga rakatsetseka, iro riri nyore kukwenya padhi yekupinza. Iko kukuya kwakakasharara kwekudzokera kumashure kunoitwa pagumbo rekukuya. Panguva yekukuya, inofanira kunyatsotonhodzwa nemvura kudzivirira kuti triangular idzoke kubva pakupisa uye kupfava kweannealing. Kukuya kunoitwa padombo reoiri kubvisa matinji nemaburrs akasara panguva yekukuya. Panguva yekukuya zvakanaka, mafuta einjini (kana turbine mafuta) anozowedzerwa kuti atonhodze. Gadzirira tafura yekusungirira nehurefu hwakakodzera. Chiratidziro chinogona kusanganiswa neingi yeutsi nemafuta eturbine kana kudhindwa tsvuku.
2. Kuchenesa, kubvisa uye kubvisa. Kutakura kuchaderedzwa uye kubviswa pamberi pekukweshwa. Kunyanya, kusanganiswa kwepamusoro pegwara rinotakura gwenzi, bhanhire rinotakura pamusoro pekutakura uye nzvimbo yekutakura yepedhi yekukanda inofanira kunyatsocheneswa.
3. Kukweva kwakashata kwegwenzi rinobereka. Chekutanga, iyo huru shaft yeturbine ichagadziriswa uye yakagadziriswa, (levelness ≤ 0.08m / M) kudzivirira shangu kuti isakwekwe kuita taper shape. Zvinyoro uye zvakaenzana purani nzvimbo yese inotakura nebanga retriangular kuti ubvise jecha uye tsvina yakasungirirwa kune inotakura nzvimbo. Tsvina yakavharirwa zvakadzika mubearing alloy ichatorwa kuti isakanganisa kunaka kwe scraping pad.
Wapedza kuchenesa jenari, bata gwara rine gwenzi pajenari, gadzirisa pini yenzvimbo, kiya sikuruu, uye woyera nzvimbo yakasanganiswa yegwenzi rinotakura uye mukaha uri pakati peBush nejenari nejeji yekunzwa kuti uone kukora kwepepa remhangura rakawedzerwa panzvimbo yakasanganiswa (padding ndeyekugadzirisa mune ramangwana). - Kazhinji, iyo padhi yemhangura yakapetwa kaviri, uye inenge 0.10 ~ 0.20mm inogona kuwedzerwa. Nheyo yekutarisa huwandu hwese hwepadhi ndeyekusiya mvumo yekukwenya ye0.08 ~ 0.20 yegwenzi rinotakura; Kune rumwe rutivi, unhu hwekutsvaira hunofanira kuvimbiswa, kune rumwe rutivi, basa rekutsvaira tile rinofanira kuderedzwa zvakanyanya sezvinobvira.
Isai pepa remhangura rakachekwa panzvimbo yakabatanidzwa yegwenzi rinotakura, bata mabhesi maviri anotakura pajenari, simbisa zvigadziriso zvekugadzirisa, shandura gwenzi rinotakura uye uchikuya. Kana iyo isingakwanisi kutenderedzwa, bvisa gwenzi rinotakura, risungirire nehafu pajenari, dzvanya nemaoko, ugoikuya neshure uchitevedza tangent direction, wobva wambundira nekukuya kana paine mukaha pakati pegwenzi rinotakura nejenari. Mushure mekugaya, chikamu chekusangana chetairi pamusoro chicharatidza dema uye chakajeka, uye chikamu chepamusoro chichava chakasviba asi chisina kujeka. Cheka chikamu chitema uye chakajeka ne triangular setback. Kana mavara matema akajeka asina kuoneka, shandisa dhizaini yekuratidzira pajenari usati wakuya. Kukuya uye kukwenya kasingaperi kusvikira kubatwa uye kucheneswa pakati penzvimbo inotakura uye magazini inosangana nezvinodiwa. Kazhinji kutaura, iyo tile yese yepamusoro inofanirwa kubatwa panguva ino, asi hapana yakawandisa yekuonana nzvimbo; Iyo clearance yatanga kuswedera kune zvinodiwa, uye pane scraping allowance ye0.03-0.05mm. Pembura makanda anotakura pamativi ese eflywheel zvakateerana.
4. Kukwenya kwepadhi yekurovera. Nekuda kwekuti trust pad inowanzokweshwa panguva yekufambisa nekuchengetedza, pachange paine mabhura pamusoro pepadhi, saka tanga wanamatira metallographic sandpaper pagirazi ndiro, uye sunda pedhi yekurovesa nekudzoka pajecha kakati wandei. Panguva yekukuya, chengetedza tile yepamusoro yakaenzana negirazi regirazi, uye nguva dzekukuya uye uremu hwetirairi imwe neimwe yakafanana, kana zvisina kudaro kuwanda kwekukanda kunosiyana zvakanyanya, kuwedzera basa rekutsvaira.
Pukuta girazi regirazi uye pedhi pedhi, dzvanya pad yekurovera pagirazi regirazi, uchikuya nekudzoka kwekanopfuura kagumi zvichienderana nekutenderera kwepadhi uye ndiro yegirazi, uye bvisa purasita yekukwenya. Mushure mokunge nzvimbo dzose dzekutakura dzakabatana zvakanaka negirazi ndiro, kutakura kunogona kuunganidzwa
5. Kutakura gungano uye kukweshwa kwakanaka. Kutanga, isa chigaro chekutakura chakacheneswa panzvimbo (panheyo, zvigadziriso zvechigaro chinotakura zvinogona kubatanidzwa munhevedzano asi kwete kuomeswa), isa gwenzi rezasi rinotakura muchigaro chekutakura, zvinyoro simudza shaft hombe mugwenzi rinotakura, gadzirisa chigaro chekutakura nekuyera gwenzi rinotakura, kuitira kuti mutsara wepakati wegwenzi rinotakura rive mumutsara wakatwasuka (≥ 2 waya), uye nzvimbo dzemberi nekumashure dzakakodzera (cushion ichawedzerwa kana mutsauko wekukwirira kwechigaro chekutakura wakura), uye wozokiya screwing yechigaro chekutakura.
Nemaoko tenderedza iyo flywheel kune akati wandei, bvisa gwenzi rinotakura uye tarisa kugoverwa kweanotakura bush contact points. Kana iyo yese inotakura nzvimbo ikasangana zvakanaka uye gwenzi rinotakura gwenzi rinosangana nezvinodiwa (kucheneswa kunoenderana nezvinodiwa zvekudhirowa. Kana zvisina kuratidzwa, tora 0.l ~ 0.2% yejenari dhayamita yekukwenya. Tshwira mapoinzi makuru netriangular faira uye deredza dense zvibodzwa; banga iro patani rinoshandiswa kutenderedza mafuta. chinodiwa ndechekuti mapoinzi ekusangana akagovaniswa zvizere mukati mechikamu chinosanganisirwa che60 ° ~ 70 ° pakati pegwenzi rezasi rinobereka, uye 2-3 mapoinzi paskweya centimita yakakodzera, kwete yakawandisa kana kudiki.
Chenesa pedhi yekurovera nejira jena. Mushure mekunge yave panzvimbo, wedzera mafuta mashoma ekuzora kune gwara rinotakura padhi, tenderedza vhiri rekubhururuka, uye wedzera axial svutugadzike yekukwenya padhi uye ndiro yegirazi zvinoenderana nenzvimbo yayo chaiyo. Maka imwe neimwe padhi (nzvimbo yepedhi yekusimudza ine gomba rekuyeresa tembiricha uye padyo nenzvimbo yakasanganiswa yakagadziriswa), tarisa padhi, tsvaira padhi yekubata zvakare, uye zvakaenzana kugaya pini kuseri kwepedhi nejira rinoputika (kukuya kwakadzikira zvakanyanya, iyo ichayerwa nemukati dhayamita micrometer kana vernier yakaenzaniswa necaliper). Kune rimwe divi, chinangwa ndechekuita kuti padhi yepamusoro ibatane negirazi ndiro, kune rumwe rutivi, kuita kuti "yakakora" yekukanda pad ive yakatetepa. Izvo zvinodikanwa kuti ese 8 thrust pads ave nekusangana kwakanaka munzvimbo chaiyo. Kazhinji kutaura, iyo pedhi yekuchinjisa yeturbine diki idiki uye mutoro idiki, saka iyo padhi yepamusoro haigone kukweshwa.
6. Kukorobha zvakanaka. Mushure mekutakura kwese kwaiswa panzvimbo uye kongiri yaoma, wedzera axial thrust kutendeuka, uye gadzirisa uye kukwenya zvinoenderana nekusangana chaiko pakati pekutakura pad uye thrust pad kuti isangane nezvinodiwa zvekudhirowa uye zvakatemwa.
Iyo longitudinal mafuta groove ichavhurwa pamativi ese ekubatana kwegwenzi rinotakura kana kune rimwe divi (oiri rekupa divi), asi inokwana 8mm misoro ichachengeterwa kumigumo yese kudzivirira kurasikirwa kwemafuta ekuzora kubva kumativi ese. Kupinza kwemafuta kwepush pad kazhinji kunosanganisira 0.5mm kudzika uye hupamhi hunenge 6 ~ 8mm. Iyo gwenzi rinotakura uye thrust pad zvinofanirwa chete mushure mekukweshwa kwakanaka
