Bulldozer bearings ndiwo musimboti wemakanika zvinhu zvinoshandiswa kutsigira zvikamu zvinotenderera, kuderedza kukwenya, uye kutumira mitoro. Iwo anowanzo sanganisira mhete yemukati (kusangana neshaft), mhete yekunze (kusangana neimba), zvinhu zvinomonereka (mabhora esimbi, rollers, nezvimwewo), uye keji (kuparadzanisa zvinhu zvinotenderedza). Zvinhu zvaro zvinonyanya kukwira kabhoni chromium inobereka simbi (yakadai seGCr15), iyo ine kuomarara kwakanyanya (kutenderedza chinhu kuoma kunosvika HRC60-65), kuramba kupfeka, uye kuramba kuneta mushure mekurapwa kwekupisa. Inogona kuenderana nemamiriro ekushanda akaoma emagetsi akadai semutoro unorema, kuzununguka, guruva, etc. Maererano nechimiro chekuputika, mabheji ebhururu anogona kupatsanurwa kuva mabheji anoputika (ayo anoderedza kuputika kuburikidza nezvinhu zvinoputika uye anonyanya kushandiswa) uye sliding bearings (izvo zvinotsigirwa ne sliding friction, zvakadai se sliding friction). Pakati pavo, mabheji ekutenderera ave chinhu chinonyanya kudiwa chinotenderera zvikamu zvema bulldozers nekuda kwekuderera kwavo kwehutsika coefficient uye yakasimba kukurumidza kugadzirisa.1. Tsigira zvinhu zvinotenderera Ipai radial uye axial positioning kune shaft components (senge drive shafts, gear shafts) kuti ive nechokwadi chekushanda kwakadzikama kwezvikamu zvinotenderera (giya, sprockets, nezvimwewo) pamatanho akatemerwa, kudzivisa kuzununguka kana kudhumhana kunokonzerwa nekugadzirisa. Shandura kutsvedza kunotsvedza kwezvikamu zvinotenderera kuva rolling friction (kana pasi friction sliding) kuburikidza nezvinhu zvinotenderera (kana sliding surfaces), kuderedza kurasikirwa kwesimba panguva yekufambisa simba, uye kunatsiridza kushandiswa kwekufambisa.Kutakura uye kutumira mitoro3. Takura iyo radial mutoro (senge huremu hwega shaft, iyo radial simba regiya meshing) uye axial mutoro (senge axial simba rinogadzirwa nekusundirwa kwefoshoro yebulldozer) panguva yekushanda kwebulldozer, uye fambisa mutoro kugoko kana furemu kudzivirira yakananga deformation yeshaft body iri pasi pekumanikidzwa.
Mamiriro ekushandisa akajairika
Kana mabulldozer ari kushanda (sekusunda ivhu rakaoma kana kukwira materu), mabearings anofanirwa kushingirira mitoro mikuru (yakadai seyemutoro wepakarepo wemavhiri ekutyaira unosvika kupfuura matani gumi), saka zvinodikanwa kusarudza mabearings ane high bearing coefficients (senge tapered roller bearings uye self-signing nekuvandudza kutakura kwavo{1}} uye kusimbisa roller zvinhu.
2. Anti kusvibiswa uye kuiswa chisimbiso
Nzvimbo yekushanda ine guruva uye ine madhaka, uye mabearings anofanirwa kushandiswa pamwe chete nekuisa chisimbiso zvinhu (sezvisimbiso zvemafuta uye zvivharo zveguruva):
Zvikamu zvakafumurwa (senge track drive wheel bearings) zvinoda kaviri miromo yemafuta zvisimbiso uye guruva rinovhara kudzivirira madhaka nejecha kupinda mujaho (tsvina inogona kukonzera "abrasive kupfeka" yemabhengi, kuderedza hupenyu hwavo neanopfuura 50%);
Mabheji ari mukati megiya bhokisi anovimba negiya mafuta ekuzora uye kuisa chisimbiso, uye zvinodikanwa kuve nechokwadi kuti giya bhokisi haribvisike.
3. Lubrication uye kupisa kupisa
Kumhanyisa kutenderera mabhengi (senge gearbox spindle bearings) inoda kumanikidzwa kudzosa nemafuta egiya (yakabayiwa kuburikidza neoiri nzira) kubvisa kupisa kunopisa (kudzivisa kutadza kwegirisi kunokonzerwa nekupisa kwakanyanya);
Low sipidhi inorema-duty bearings (senge bucket pin roller bearings) inoda kugara ichizorwa girizi (kamwe pamaawa 200 ega ega) kugadzira firimu remafuta uye kuderedza kukweshana.
·Dambudziko: Kutadza kwekutanga kutsigira mavhiri mavhiri kunokonzerwa nerock impact. Solution:
Kutora mitsara mitatu yemabhengi ane tapered roller (ne50% yekuwedzera mukutakura-kutakura simba)
Optimization yeRoller Logarithmic Curve (Uniformization yeStress Distribution)
Upgrade lubricating grease to fully synthetic lithium based grease (drip point>260 degree)
2. Nzvimbo yekuvaka manyoro:
·Dambudziko: Kusavhara chisimbiso kunokonzerwa nekupindirwa kwemvura/sediment · Innovative dhizaini:
Kaviri miromo mafuta chisimbiso + magineti fluid chisimbiso (isina mvura chiyero IP68)
Wedzera migero yemvura kuchigaro chekutakura (seCaterpillar D6T dhizaini)
3. Kushanda munzvimbo-dzepamusoro:
·Pain point: Kudzikira tembiricha ye -50℃C inoita kuti girizi riome. Countermeasure:
Pre yakazadzwa yakaderera-girisi yematembiricha (inokwanisa kuyerera pa -60 degrees C)
Sarudza yakakwira kusimba inotakura simbi (Charpy impact simba Yakakura kupfuura kana yakaenzana ne100J)
