Mabheyaringi ezvitima zvinotenderera

Mabheya ezvitima zvinotenderera anoreva mabheya anoshandiswa muzvitima zvinotenderera uye zvitima zvinotenderera. Mabheya ari pazvitima anosanganisira mabheya ezvitima zvinotenderera, mabheya emagetsi anotenderera, mabheya emagetsi anotenderera, mabheya emagetsi anotenderera uye mabheya ehurongwa hwekutonhodza, nezvimwewo, nepo mabheya ari pazvitima ari mabheya ezvitima zvinotenderera, mabhokisi ezvitima zvinotenderera anowanzo shandisa mabheya mapfupi anotenderera, uye mabhokisi ezvitima zvinotenderera anonyanya kushandisa mabheya ezvitima zvinotenderera, uye mhando, chimiro uye mashandiro emabheya ezvitima akafanana nemabheya ezvitima zvinotenderera.

 

1.Kutakura bhokisi reAxle

 

Vhiri remota rakabatana nemuviri wemota kuburikidza nebhokisi re axle, chitubu nefuremu yebogie, uye bearing yebhokisi re axle inotakura zvakananga simba rekukweva remota uye radial ne axial impact yerail pavhiri, pamusoro pekutumira simba rekukweva uye mimwe mitoro inogadzirwa ipapo, saka bearing yebhokisi re axle inofanira kunge iine bearing capacity yakakura, inogona kutsungirira kuvhunduka nekudengenyeka, uye inofanira kunge iine hupenyu hwakareba, kuchengetedzeka nekuvimbika, saizi diki uye mhando; Zviri nyore kuongorora nekuchengetedza, nezvimwewo. Naizvozvo, mabearing emota anowanzo shandisa mabearing series asina kujairika uye mamiriro ehunyanzvi ebearing akakosha, uye mabearing anoshandiswa kazhinji ane mapoka matatu anotevera.

 

(1)Mabheyaringi ecylindrical rollerMaekisero mazhinji emota dzedhiziri nedzemagetsi anoshandisamabheyaringi eroller ane cylindricalKune mhando mbiri huru.

 

1)Mitsetse mina yemabheyaringi e cylindrical roller

 

Bearing yebhokisi rema "locomotive axle box bearing" yekuChina ndiyo yakatanga kushandiswa, uye nhamba huru ye "loaded" imhando ye "four-row cylindrical roller bearing" 972832. Bearing iyi ine mutoro wakakwira uye inogara kwenguva refu, uye mutoro wayo we "dynamic" i1445kN. Sezvo ichingogona kutakura mitoro ye radial chete, kwete mitoro ye axial, zvakakosha kugadzira mudziyo unodzivirira masimba e axial mubhokisi re axle.

 

2) Mabheyaringi eroller ane mitsara miviri

 

Mabhokisi eDongfanghong 2, 3, 5, 21 neBeijing emota dzemuchina dzese dzinoshandisa mabheya eroller ane mitsara miviri ine ma "double-row cylindrical roller bearings" 982832T, ane ma "radial forces", uye mabheya ebhora ane "angular contact ball bearings" 146132T ane ma "axial loads".

 

(2)Mabheyaringi anotenderera akatenderera

 

Chakanakira kushandisa mabheya edenderedzwa redenderedzwa redenderedzwa nderekuti hapana mudziyo wekutsiva kutenderera pakati pebhokisi redenderedzwa nefuremu yebogie. Beya redenderedzwa redenderedzwa reND2 ibheya redenderedzwa ...

 

(3)Mabheyaringi anotenderera akatetepa

 

Rudzi urwu rwebearing runoshandiswa mubhokisi re axle re locomotive i bearing ine tambo mbiri, uye locomotive ye ND5 diesel ine bearing yerudzi rwe AP. Rudzi urwu rwebearing rune saizi ye inch, uye runowanzo shandiswa mu B, C, D, E, F, G nedzimwe nhanho, dzinoshandiswa kuma axles akasiyana.

 

2.Kutakura mota yekutakura

 

(1) Simba rekutakura mota yekufambisa

 

Mota inodhonza ndiyo midziyo mikuru musystem yekutumira maroketi emagetsi nemaroketi edhiziri anodhonza emagetsi, uye armature bearing ndeimwe yezvikamu zvayo zvikuru.

 

1)Mabheyaringi ekutumira divi rimwe chete

 

Chigadziko chinowanzo tsigirwa ne double fulcrums, magumo ekugadzira giya rekuisa anotsigira kufamba, uye magumo e commutator anotsigira nzvimbo. Bearing inobuda iri pedyo negiya, iro rinonyanya kumanikidzwa, uye ndiyo key bearing yema bearing maviri e armature. Kuti kuderedze mutoro, mhando yeNU ye cylindrical roller bearing isina inner ring flange inowanzo shandiswa. Magumo e commutator anowanzo tora cylindrical roller bearing NUP type ine single flange ine flat retaining ring pa inner ring, uye kunewo cylindrical roller bearing ine single flange ine inner flange ne bevel retaining ring pa commutator end.

 

2) Mabheyaringi ekutumira mativi maviri

 

Kana simba remota rakakura, kana transmission yedivi rimwe chete ichiri kushandiswa, mutoro wekutakura uri pamagumo egiya wakakura zvakanyanya, uye zvakaoma kusarudza bearing iyo mutoro wesimba wakayerwa uye kumhanya kwekupedzisira zvinogona kusangana nezvinodiwa, saka nzira yekutumira ine mativi maviri inogona kuchinjwa kana dhizaini yemota ichibvumira. Chakanakira transmission ine mativi maviri ndeyekuti magiya esimbi anotenderera anogona kushandiswa, kuitira kuti makona ehelix emagiya maviri aenzane uye divi rekutenderera rakapesana, kuitira kuti uwane mhando yekutumira yakagadzikana pasina kugadzira mutoro weaxial. Bearing yakakodzera chinangwa ichi imhando yeNU yesimbi isina flange muring yemukati, kana giya resimbi rinoputika richiri kushandiswa pakutumira mativi maviri, bearing inogona kumira simba re axial rinofanira kusarudzwa, uye cylindrical roller bearing NJ mhando ine flange imwe muring yemukati inowanzo shandiswa.

 

(2)Mubato wekutakura mota unobereka shaft bearing

 

Mamota ekubata anowanikwa neaxle anowanzo tsigirwa pabogie netsvimbo yekugadzirisa kune rumwe rutivi, uye paaxle kune rumwe rutivi neshaft bearing.Mabheyaringi ecylindrical roller, mabheyaringi edenderedzwauyemabheyaringi anotenderera akatetepazvakashandiswa.

 

Cylindrical roller bearings dzakakodzera ma locomotives anomhanya zvikuru, uye ma grisi replenishment cycles awo akareba, uye kuiswa nekugadzirisa kuri nyore, kunyanya kana uchishandisa integral shell, mukana uyu unogona kuratidzwa zvizere. Kugadzika kwe tapered roller bearings kwakanaka, izvo zvinobatsira kuona kuti magiya akarurama, asi zvakaoma kugadzirisa kuungana kwawo nekupatsanurwa kwawo uye axial clearance. Kugadzika kwema seti maviri ema spherical roller bearings, kunyanya disassembly, kwakaoma kupfuura kwema tapered roller bearings, asi kunogona kugamuchira kukotama kwe shaft. Shaft bearing ye traction motor ye electric locomotive muChina inoshandisa spherical roller bearing, uye modhi yayo i3G3053148T.

 

(3)Mabheyaringi ejenareta yekubata

 

Muviri wejenareta yedhiziri yemazuva ano inofambiswa nemagetsi inowanzoiswa pamucheto wemuviri pamucheto weinjini yedhiziri. Ingave yakaiswa nenzira iyi kana neimwe nzira, mugumo we armature hauwanzo shongedzwa nemabheyaringi, uye armature inowanzo tsigirwa pa crankshaft kana output shaft yeinjini yedhiziri kuburikidza ne elastic coupling, kuitira kuti saizi yejenareta ipfupike.

 

Mugumo wekunze we armature shaft unogona kushandiswa nemabheyaringi eroller ane cylindrical, uye dzimwe nguva kuti zvive nyore kuenderana neinjini yedhiziri panguva yekuisa, mabheyaringi edenderedzwa anotenderera anogonawo kushandiswa.

 

3. Mabheyaringi ehurongwa hwekufambisa hydraulic hwemotokari dzedhiziri

 

Sisitimu yekufambisa hydraulic yedhiziri locomotive inowanzo sanganisira zvikamu zvitatu: hydraulic transmission box, cardan shaft, uye axle gearbox. Dzimwe nguva ma shunting locomotives anewo work condition gearbox, iyo ine ma rolling bearings akawanda.

 

(1) Giya remagiya eHydraulic

 

Maitiro ekushanda kwebhokisi remagetsi edhiziri nderekushandura simba reinjini yedhiziri kuita simba remota inotyaira kuburikidza ne hydraulic torque converter kana chitima chichidhonzwa; Pakushandisa simba remagetsi, brake remagetsi rinoshandiswa kutora simba remagetsi remavhiri emota. Masisitimu akati wandei eshaft akarongwa mu hydraulic gearbox, uye rutsigiro rweshaft yega yega rwune ma rolling bearings.　　

 

(2) Giya repakati rebhokisi remagiya

 

Zvikamu zvikuru zvegiya repakati ndiro shaft yekupinda neshaft yekubuda imwe neimwe ine magiya maviri, uye giya riri pane imwe shafts ishift gear, uye shaft negiya rayo zvine clutch mechanism, iyo inogona kuita kuti rimwe remagiya ribatane neshaft uye simba rekutumira; Rimwe giya riri kungomira muchiitiko ichi. Giya rekuchinja neclutch zvinowanzoiswa pashaft yekupinda, nekuti torque yekupinda idiki, izvo zvinobatsira kuderedza saizi yespline clutch nehukuru hwebearing.

 

(3) Giya rebhokisi reAxle

 

4. Chinobereka crankshaft yeinjini yedhiziri

 

Zvakanakira zvikuru zve crankshaft bearing yeinjini yedhiziri uchishandisa rolling bearing zvinongogumira kune injini yedhiziri inomhanya zvikuru, inova: kurasikirwa nekukweshana kudiki, kushanda zvakanaka kwemuchina, kushanda kwakavimbika uye hupenyu hurefu hwebasa; Kunyorovesa kuri nyore, radiator yemafuta diki, nezvimwewo. Zvichienzaniswa nekushandiswa kwema sliding bearing, zvikanganiso zvayo zvikuru ndeizvi: mutengo wakakwira, mhando yakakura, zvinodiwa zvehunyanzvi zvekuunganidza ma bearing nema crankshafts, kugadzirisa nekutsiva zvisina kunaka, uye ruzha rukuru.

 

Kune macrankshafts einjini yedhiziri ine silinda imwe chete nesilinda mbiri, mabheyaringi ekirasi 0 anonyanya kushandiswa; Kune macrankshafts einjini yedhiziri ane simba guru uye anomhanya, nekuda kwekurema kwawo kukuru, mabheyaringi eroller ecylindrical chete ndiwo anowanzo shandiswa.
