Iinkcukacha zeeNeedle Roller Bearings

Iinkcukacha zeiibheringi zerola yenalitiziquka imigangatho kunye neemfuno zoyilo lwazo, ukwenziwa kwazo, ukulinganiswa kwazo kunye nokusetyenziswa kwazo. Nazi ezinye zeenkcukacha eziphambili:

 

Ubushushu bokusebenza

Ubushushu bokusebenza bububanzi bobushushu apho ibheyari ingasetyenziswa khona. Kwiindawo ezinobushushu obuphantsi, i-viscosity ye-lubricant iyanda, ifuna umthwalo omncinci ophezulu. Ke ngoko, xa ukhethaiibheringi zerola yenaliti, kuyimfuneko ukuqwalasela ubushushu bendawo yokusebenza kunye nokukhetha indlela efanelekileyo yokuthambisa kunye nendlela yokuthambisa.

 

Isantya sokubhekisa kunye nesantya esilinganiselweyo

Isantya sokubhekisa sisantya sokujikelezisa apho ukuveliswa kobushushu kunye nokusasazwa kufikelela khona kumlinganiselo, ngelixa isantya sokukhawulezisa sisantya esiphezulu ibheyari eyenzelwe ukusebenza ngaso. Ezi parameter zimbini zixhomekeke kumandla ekheyiji yokuthwala, umgangatho wokuthambisa, amandla e-centrifugal kunye nokujikeleza, ukuchaneka kokwenziwa kweebheriya, kunye neempawu ze-lubricant. Ke ngoko, xa uyila kwaye usebenzisa iibheringi ze-needle roller, kuyimfuneko ukuqinisekisa ukuba isantya sazo singaphakathi koluhlu lwesantya sokubhekisa kunye nesantya sokukhawulezisa ukuqinisekisa ukusebenza okuzinzileyo kunye nokwandisa ubomi benkonzo.

 

Umlinganiselo

Uninzi lweebheringi lulinganiswa ngeendlela ezintathu: ububanzi bangaphakathi (ID), ububanzi bangaphandle (OD), kunye nobubanzi (W). Ukulinganiswa kweebheringi zeenaliti kukwalandela lo mgangatho. Xa ulinganisa, kuyimfuneko ukulandela ulandelelwano lwebubanzi bangaphakathi (ID) × ububanzi bangaphandle (OD) × ububanzi (W) ukuqinisekisa ukuchaneka kunye nokuhambelana.

 

Imodeli kunye nobukhulu

Imodeli kunye nobukhulu bayoiibheringi zerola yenalitizimiselwa ngokweemeko zesicelo sazo kunye neemfuno zokusebenza. Iimodeli eziqhelekileyo ziquka iibheringi zeroli zenaliti zangaphandle ezistampuweyo, iibheringi zeroli zenaliti ezihlengahlengiswayo ezivulekayo, iibheringi zeroli zenaliti ezithululwayo, njl. Imodeli nganye ineemeko zayo ezithile zesicelo kunye neenzuzo. Umzekelo, iibheringi zeroli zenaliti zangaphandle ezistampuweyo zineringi yangaphandle estampuweyo encinci, ukuphakama okuphantsi kwecandelo elinqamlezileyo, kunye nomthamo ophezulu womthwalo; iibheringi zeroli zenaliti ezihlengahlengiswayo ezivulekayo zinokulungisa umthwalo we-axial ukuze kutshintshe ulwandiso lweringi yangaphandle, ngaloo ndlela kulungiswe i-radial internal clearance. Xa ukhetha iibheringi zeroli zenaliti, kuyimfuneko ukukhetha imodeli kunye nobungakanani obufanelekileyo ngokusekelwe kwimeko yesicelo kunye neemfuno zokusebenza.

 

Imigangatho neMimiselo

Ukwenziwa nokusetyenziswa kweiibheringi zerola yenalitikufuneka bathobele uthotho lwemigangatho nemigaqo. Le migangatho nemigaqo ibandakanya i-ASTM F2162 kunye ne-ASTM F2163, ephathelele iibheringi, iiroli, kunye neeroli zeenaliti, kunye ne-ISO 281, ISO 3031, kunye ne-ISO 3096, ezigubungela ukulinganiswa komthwalo oguquguqukayo weebheringi eziqengqelekayo, iindibano zeenaliti ezithungelweyo kunye neekheyiji, kunye nobukhulu kunye nokunyamezela kweeroli zeenaliti. Le migangatho nemigaqo ibonelela ngesikhokelo esibalulekileyo kunye nokuqinisekiswa koyilo, ukwenziwa, kunye nokusetyenziswa kweebheringi zeenaliti eziqengqelekayo.

 

Ngoyilo lwabo olulodwa, ukusebenza okuphezulu, kunye noluhlu olubanzi lwezicelo,iibheringi zerola yenalitiziye zaba yinxalenye ebalulekileyo kushishino lwanamhlanje. Ngokufumana ukuqonda okunzulu ngeemeko zokusetyenziswa kunye neenkcukacha zeebheringi zerola yeenaliti, sinokukhetha ngcono kwaye sisebenzise iintlobo zeebheringi ezifanelekileyo kwiimfuno ezithile, siphucule ukusebenza kwezixhobo kunye nobomi benkonzo. Ngokuqhubela phambili kwezobuchwepheshe okuqhubekayo kunye neemfuno ezikhulayo zokusetyenziswa, iibheringi zerola yeenaliti ziya kuba nethuba elibanzi lophuhliso kwixesha elizayo. Silangazelela ukuba iibheringi zerola yeenaliti zidlale indima enkulu kwiinkalo ezininzi, ziqhube ishishini loomatshini ukuya kwinqanaba eliphezulu.
