Umahluko oPhambili kuYilo lweSakhiwo kunye noFakelo phakathi kwee-Angular Contact Bearings kunye nee-Thrust Spherical Plain Bearings

 

Kwiinkqubo zothumelo loomatshini,ibhereyithaUkukhethwa kuchaphazela ngqo ukuchaneka kokusebenza kwesixhobo kunye nobomi baso.iibheringi zoqhagamshelwano ze-angular(ezifana nothotho lwe-GAC) kunyeiibheringi ezicacileyo ezityhalwayo(ezifana nothotho lwe-GX) zisetyenziswa kakhulu ukuthwala imithwalo ye-axial, uyilo lwayo lwesakhiwo, ubungakanani bofakelo, kunye neendlela zokudlulisela amandla zahlukile ngokusisiseko. Eli nqaku, ngokuthelekisa iiparameter eziphambili kunye nohlalutyo lwendlela yoomatshini, lityhila umahluko ophambili phakathi kwezi zimbini kwizicelo ezisebenzayo.

 

1. Umahluko Obalulekileyo Kuyilo Lwezakhiwo

 

Iibheringi zoqhagamshelwano ze-angular(uthotho lwe-GAC) zisebenzisa uyilo apho izangqa zangaphakathi nezangaphandle zenza uqhagamshelwano olujikelezayo kwicala elinye, nto leyo ebenza bakwazi ukumelana ngaxeshanye nemithwalo edibeneyo yeradial kunye ne-axial. Uphawu lwazo oluchazayo yi-engile yoqhagamshelwano, emisela icala kunye nomthamo wokudluliselwa komthwalo. Iibheringi ezicacileyo ze-Thrust spherical (uthotho lwe-GX), kwelinye icala, zenzelwe imithwalo ejikelezayo kuphela. Ulwakhiwo lwazo lugxininisa umthamo womthwalo ojikelezayo kunye nokuguquguquka okuguquguqukayo. Zihlala zisetyenziswa kwiimeko zokusebenza ezikhawulezayo, ezinzima, kunye nezihlengahlengiswayo nge-angular.

 

II. Uthelekiso lweeParamitha zoBukhulu boFakelo lweSihluthulelo

 

Ngokuphathelele ubungakanani bofakelo, umahluko ophambili phakathi kwezi zimbini ubonakala kuyilo lwamagxa kunye nokususwa kwe-axial:

 

Ukuphakama Kwamagxa (Db): Iibheringi zoqhagamshelwano ze-angular zinemfuneko engqongqo ekuphakameni kwegxalaba le-shaft kunye negxalaba le-bore, ziqinisekisa ukusasazwa komthwalo ofanayo phakathi kweendandatho zangaphakathi nezangaphandle ukuze kuthintelwe uxinzeleko loxinzelelo. Iibheringi ezicacileyo ezityhalwayo, kwelinye icala, ngokuyintloko zithwele amandla e-axial, ngoko ke uyilo lwamagxa azo lubeka phambili ukuthamba kunye nokuqina komphezulu wenkxaso, okuvumela ulawulo lokuphakama olukhululekileyo.

 

Ukucaciswa kwe-Axial (S): Iibheringi zoqhagamshelwano ze-angular zihlala zifuna ukulayisha kwangaphambili ukuphucula ukuqina kunye nokuchaneka kokujikeleza, okwenza ulawulo lokucaciswa kwe-axial lube lubalulekile. Oku kudla ngokufezekiswa ngokufanisa okanye ukushimming. Iibheringi ezicacileyo ze-Thrust spherical, ngokwahlukileyo, zivumela ukudlala okukhulu kwe-axial, kwaye uyilo lwazo lwe-S-value lunyamezela ngakumbi, luvumela zombini ukushukuma kunye nokungalungelelani.

 

III. Iindlela ezahlukeneyo zoThumelo lwaMandla

 

Uhlalutyo lwamandla olunemilinganiselo emithathu lubonisa ukuba iibheringi zoqhagamshelwano ze-angular zidlulisela imithwalo ukusuka kwiringi yangaphandle, ngokusebenzisa izinto eziqengqelekayo, ukuya kwiringi yangaphakathi ecaleni kwe-engile yoqhagamshelwano, nto leyo edala ukuhamba kwamandla okuthe tyaba okulinganisela zombini izinto ze-radial kunye ne-axial. Ngokwahlukileyo koko, iibheringi ezicacileyo ze-thrust spherical zidlulisela amandla ngokuthe nkqo kwi-axis, ngokuthe ngqo kumphezulu woqhagamshelwano olujikelezayo, zigxininisa inkxaso ye-axial kunye nokuzilungelelanisa.

 

IV. Iingcebiso zokukhetha nokufaka

 

Iibheringi zoqhagamshelwano ze-angular zifanelekile kwizicelo ezikhawulezayo nezichanekileyo (ezifana nee-spindles zezixhobo zomatshini). Ulawulo oluchanekileyo lokuthwala umthwalo kwangaphambili kunye nokumelana nokulingana kubalulekile ngexesha lokufakwa.

 

Iibheringi ezicacileyo ezitsolozilungele ngakumbi ukusetyenziswa kwesantya esiphantsi, umthwalo onzima, kunye nokungasebenzi kakuhle kwe-angular (ezifana namalungu kumatshini wokwakha). Ukufakelwa kugxila ekuqinisekiseni umphezulu oxhasayo ozinzileyo kunye nokuthambisa okwaneleyo.

 

Ukuqonda umahluko osisiseko kwisakhiwo, ubukhulu, kunye nokuziphatha koomatshini phakathi kwezi ntlobo zimbini zeebheringi kuya kukunceda wenze izigqibo zokukhetha ezichanekileyo ngexesha lesigaba soyilo kwaye uphephe ukusilela kwangethuba okanye ukuwohloka kokusebenza ngenxa yokusetyenziswa gwenxa.
