Ama-self-lubricating bearings angakwazi ukuxazulula ngokuphumelelayo izinkinga zokugcoba, ezifana nokushisa okuphezulu, isivinini esiphansi, umthwalo omkhulu, uthuli olunzima, ukuwasha, umthelela kanye nokudlidliza kwemishini yemishini.Ukukhethwa kwezinto ezithwala ukuzigcoba kubaluleke kakhulu.Indlela yokugcobisa yezinto ezithwalayo ezizigcobayo ukuthi amanye ama-molecule ezinto ezithwalayo ezizigcobayo azohamba aye endaweni yensimbi yeshafi ngesikhathi sokuslayida phakathi kwe-shaft nomkhono we-shaft, futhi agcwalise amabala amancane angajwayelekile.Ungqimba oluzinzile lwe-lubricant oluqinile lubangela ukungqubuzana phakathi kwezinto zokugcoba eziqinile futhi luvimbele ukuguga kwe-adhesive phakathi kweshaft nomkhono.Ngakho-ke kufanele kukhethwe kanjani ama-bearings azigcobayo?Okulandelayo uhlelo oluncane lwamabheringi azigcobayo e-Hangzhou ukuze wazi ngakho.

1. Isakhiwo esithwalayo i-self-lubricating i-self-lubricating block iyinhlanganisela ye-self-lubricating block, eshunyekwe emkhonweni wensimbi, indlela yokubhoboza ubukhulu obufanele bembobo endaweni yokushayisana kwensimbi ye-bearing matrix, bese ushumeka i-molybdenum disulfide, i-graphite. , njll. Yenziwe ngebhulokhi eyinhlanganisela yokuzithambisa.Indawo yokungqubuzana yamabheringi kanye nezinto zokugcoba eziqinile zingama-25-65%.Amabhulokhi azithambisayo aqinile enza kahle emazingeni okushisa afinyelela ku-280°C.Kodwa, ngenxa yamandla alo aphansi emishini, amandla okuthwala abuthakathaka futhi kulula ukuguquguquka, ngaleyo ndlela angakwazi ukufakwa emgodini wezimbobo noma insimbi ukucindezela amaphutha, kanye ne-self-lubricating block ukugcoba ingxenye yensimbi yomthwalo wokusekela. lolu hlobo lomshini wokugcobisa oluzigcobayo luwuhlobo lwefilimu yokugcoba eqinile ezinzile, amanye ama-molecule azigcoba ngokwawo ohlelweni lokuslayida phakathi komkhono we-shaft nomkhono we-shaft athuthela e-eksisi ebusweni bensimbi, ngaleyo ndlela. gcwalisa ukungahambi kahle okuncane.Idala ukungqubuzana phakathi kwamafilimu okugcoba okuqinile futhi ivimbele ukuguga kwe-adhesive phakathi kwe-shaft nomkhono we-shaft.Le nhlanganisela enengqondo ihlanganisa izinzuzo ezihambisanayo ze-alloy yethusi kanye nezinto ezingezona ezensimbi zokunciphisa ukungqubuzana kwensimbi, ukungabi namafutha, izinga lokushisa eliphezulu, umthwalo omkhulu, isivinini esiphansi, i-anti-fouling, ukumelana nokugqwala nokufuduka ezindaweni ezinomsakazo oshisa kakhulu.Ikakhulukazi efanelekayo amplitude.Isetshenziswa ngaphansi kwezimo ezikhethekile zokusebenza ngokuyicwilisa esixazululweni esinjengamanzi futhi ayidingi ukungezwa kwamafutha.

2. Indawo ye-self-lubricating block ihlobene nesivinini sokusebenza nokumelana nokucindezela kwe-self-lubricating block.Ukusebenza kancane, ukumelana nomfutho ophezulu, kanye nendawo yensimbi enkulu ngangokunokwenzeka.Isibonelo, ibhulokhi yokuzithambisa yesondo elihambayo lemoto ye-spindle clutch ithatha cishe u-25% wendawo, futhi i-spindle bear ye-drag mechanism idinga ukugcotshwa ngokugcwele, futhi umthamo wokuthwala ingcindezi awumkhulu.Amabhulokhi azithambisayo athatha cishe u-65% wendawo.

3. Izidingo zobuchwepheshe ze-bushing materials bushing kumele zenziwe nge-alloy copper, i-bushing inobunzima obuphezulu, ngokuvamile idinga ukwelashwa ngokushisa, ubulukhuni be-HRC45.

4. Ukwakheka kwebhlokhi elizithambisayo kanye nezidingo zikaMose.Kunezinhlobo ezimbili zamabhulokhi azigcobayo, ayi-cylindrical kanye nama-rectangular, angaba yicylindrical noma ama-rectangular kuye ngendawo okuhlala kuyo.Kungakhathaliseki ukuthi ukuma kwayo, kufanele ifakwe ngokuphephile ukuze ingawi ngesikhathi sokusebenza.

I-coefficient yomugqa yokunweba yebhulokhi ezithambisayo cishe iphindwe ka-10 kuneyensimbi.Ukuze kuhlangatshezwane nezinguquko zokushisa ezithwalayo, ukucaciswa phakathi kwe-shaft kanye ne-bushing kuyanda kusukela ekulinganeni okunamandla kwe-4-step kwengxenye yensimbi (D4 / DC4) kusuka ku-0.032 kuya ku-0.15 mm kuya ku-0.45 kuya ku-0.5 mm.I-self-lubricating block iphuma ngo-0.2-0.4mm kusukela kunsimbi eqhumayo ohlangothini olulodwa lwepheya yokushayisana.Ngale ndlela, isikhathi sokuqala sokusebenza sokusebenza kokuthwala sigcotshwa ngokugcwele, ngaleyo ndlela kunciphisa ukusetshenziswa kokudluliswa kwamandla.

Okungenhla yikho konke okuqukethwe mayelana nendlela yokukhetha ama-bearings azigcobayo.Siyabonga ngokuqonda kwakho nokusekela kwakho!
