Umthelela we-Lubrication Groove Design ekusebenzeni kwama-Sliding Bearings

Ama-groove okugcoba abalulekile ekuhlinzekeni nasekusabalaliseni uwoyela kuwo ama-sliding bearings, kodwa zimelela ukuyekethisa komklamo obalulekile. Umsebenzi wabo oyinhloko ukuqinisekisa ukugcotshwa okwanele, ikakhulukazi ngesikhathi sokuqala nangaphansi kwezimo zejubane eliphansi. Nokho, ama-grooves nciphisa ngokungaphakathi indawo yokuthwala umthwalo futhi uphazamise ifilimu kawoyela ye-hydrodynamic eqhubekayo okudingekayo ekusebenzeni kahle. Ngakho-ke, ifilosofi yokuklama emaphakathi iwukuba wandise ukusatshalaliswa kwe-lubricant ngomthelela omncane olimazayo ekukhiqizeni ingcindezi. Idizayini ye-groove elungile ibhalansi ngokucophelela yendawo, i-geometry, nohlobo, oluhambisana nezidingo ezithile zokusebenza (umthwalo, isivinini, isiqondiso).

Uma kuziwa i-sliding bear ukusebenza kanye nesikhathi sokuphila, umklamo we-lubrication groove uyinkosi. I-bearing surface yenziwe ngobunono ukuze ifake ama-grooves avumela ukuthambisa kusatshalaliswe, okuholela ekungqubuzaneni okuncane nokusebenza kahle. Umthamo womthwalo, ukuchithwa kokushisa, nokumelana nokugqoka konke kuthinteka kakhulu ekuklanyweni kwale misele. Ukuphatha kahle, impilo yokusebenza, kanye nokusebenza kwesistimu konke kungathuthukiswa abakhiqizi ngokulungisa iphethini, ukujula, nobubanzi bemigodi yokugcoba. Imibono emisha kule ndawo ishintsha indlela izinto ezisetshenziswa ngayo emikhakheni eminingi ehlukene. Ukuhlangana okuyinkimbinkimbi phakathi kokusebenza kwe-plain bearing kanye ne-lubricating groove kuyisihloko sale ndatshana.

Okuyisisekelo kwe-Lubrication Groove Design kuma-Sliding Bearings

Ukusebenza kwebheringi eshelelayo kulawulwa umgomo wokugcoba nge-hydrodynamic:

Ijenali ejikelezayo (i-shaft) ihudula i-viscous lubricant ibe yi-wedge eguqukayo phakathi kwayo kanye nolayini othwalayo.

Lesi senzo sidala umfutho woketshezi oluphezulu phakathi kwe-wedge, ephakamisa ijenali futhi isekele umthwalo wefilimu encane yamafutha.

Lokhu kuhlukaniswa kwefilimu ewuketshezi kubangela ukungqubuzana okuphansi kakhulu nokugqokwa okunganakwa.

Isinyathelo esibalulekile: Noma yikuphi ukungaqhubeki endaweni ethwalayo—ikakhulukazi umsele—kuphazamisa le nqubo yokukhiqiza ingcindezi.

Umthelela onemininingwane kumapharamitha okusebenza abalulekile

A. Ikhono Lokuthwala Imithwalo (Isici Esibaluleke Kakhulu)

Umthelela Omubi: I-groove ebekwe ngqo ngaphakathi indawo yokulayisha (isifunda lapho umfutho we-hydrodynamic uphakeme) kuyinhlekelele. Isebenza njengesiteshi sokusiza ingcindezi, ivumela ifilimu yamafutha esekelayo ukuba ibaleke. Lokhu kunganciphisa umthamo womthwalo wokuthwala ngo-80-90%.

Okubalulekile Kwedizayini: Ama-grooves kufanele abekwe ngaphandle kwe-arc yokuqala ethwala umthwalo. Ngomthwalo omile ongashintshi, lokhu kusho ukubeka ama-grooves eduze komugqa wokuhlukanisa noma phezulu (okungalayishiwe) uhhafu wokuthwala.

B. Izinga Lokugeleza Kwamafutha kanye Nokuphathwa Kokushisa

Umthelela Omuhle: Ama-grooves ayimigudu eyinhloko yokuhlinzeka uwoyela omusha, opholile. Isistimu ye-groove esebenzayo iqinisekisa ukugeleza okwanele ukususa ukushisa okuphikisanayo, ukuvimbela ukukhuphuka kwezinga lokushisa okuyingozi.
