Iibheringi zokuzithambisa zinokucombulula ngempumelelo iingxaki zokuthambisa, ezifana nobushushu obuphezulu, isantya esiphantsi, umthwalo omkhulu, uthuli olunzima, ukuhlamba, impembelelo kunye nokungcangcazela kwezixhobo zoomatshini.Ukukhethwa kwezinto ezithwala i-self-lubricating kubaluleke kakhulu.Indlela yokuthambisa yezinto ezizithambisayo kukuba ezinye iimolekyuli ezikwisixhobo sokuzithambisa ziya kuhamba ziye kumphezulu wesinyithi weshafti kwinkqubo yokutyibilika kokutyibilika phakathi kweshaft kunye nomkhono we-shaft, kwaye zizalise amabala amancinci angaqhelekanga.Umaleko ozinzile we-lubricant eqinileyo ibangela ukukhuhlana phakathi kwezithambisi eziqinileyo kwaye unqanda ukuguga kwe-adhesive phakathi kweshaft kunye nomkhono.Ke kufuneka kukhethwe njani iibheringi zokuzithambisa?Oku kulandelayo luhlelo oluncinci lwe-Hangzhou self-lubricating bearings ukwazi ngayo.

1. Ulwakhiwo lokuthwala i-self-lubricating bear lubricating self-lubricating block, efakwe kwi-sleeve yesinyithi, indlela yokubhobhoza ubungakanani obufanelekileyo bomngxuma kwi-fiction surface yentsimbi ye-matrix yokuthwala, kwaye emva koko udibanise i-molybdenum disulfide, i-graphite. , njl. Yenziwe ngebloko edibeneyo yokuzithambisa.Ummandla we-friction of bearings kunye ne-lubricants eqinile yi-25-65%.Iibhloko eziqinileyo zokuzithambisa zisebenza kakuhle kumaqondo obushushu ukuya kuma 280°C.Kodwa, ngenxa yamandla ayo omatshini aphantsi, umthamo wokuthwala ubuthathaka kwaye kulula ukuguqulwa, ngaloo ndlela unokufakwa kwi-groove yemingxuma okanye isinyithi ukucinezela iziphene, kunye nebhloko yokuzithambisa ukuze uthambise inxalenye yentsimbi yomthwalo wenkxaso. Olu hlobo lwesixhobo sokuthambisa esizithambisayo luhlobo lwefilim yokuthambisa ezinzileyo, ezinye zeemolekyuli ezizithambisa ngokwazo kwinkqubo yokutyibilika kokutyibilika phakathi kweshafti kunye nomkhono we-shaft uhanjiswe kwi-axis yomphezulu wesinyithi, ngaloo ndlela. gcwalisa isitenxo esincinci.Yenza ingxabano phakathi kweefilimu zokuthambisa eziqinileyo kwaye ithintele ukuguga kwencamathela phakathi kweshaft kunye nomkhono weshaft.Olu didi olunengqiqo ludibanisa iingenelo ezincedisayo ze-alloy yobhedu kunye nezixhobo zokunciphisa i-friction non-metallic, i-oyile-free, ubushushu obuphezulu, umthwalo ophezulu, isantya esiphantsi, i-anti-fouling, ukumelana nokugqwala kunye nokufuduka kwiindawo ezinomsakazo ophezulu.Ngokukodwa kufanelekile kwi-amplitude.Isetyenziswe phantsi kweemeko ezikhethekileyo zokusebenza ngokuyidibanisa kwisisombululo esinjengamanzi kwaye ayifuni ukongezwa kwegrisi.

2. Ummandla webhloko ye-self-lubricating inxulumene nesantya sokusebenza kunye nokumelana noxinzelelo lwebhloko yokuzithambisa.Ukusebenza okucothayo, ukumelana noxinzelelo oluphezulu, kunye nommandla wesinyithi omkhulu kangangoko kunokwenzeka.Umzekelo, ibhlokhi yokuzithambisa yevili lokuhamba lemoto ye-spindle clutch ithatha malunga ne-25% yendawo, kwaye i-spindle ye-spindle yendlela yokutsala kufuneka ifakwe i-lubricated ngokupheleleyo, kwaye umthamo wokuthwala uxinzelelo awukho mkhulu.Iibhloko zokuzithambisa zithatha malunga ne-65% yendawo.

3. Iimfuno zobugcisa ze-bushing materials bushing kufuneka zenziwe nge-alloy copper, i-bushing inobunzima obuphezulu, ngokuqhelekileyo kufuneka iqhube unyango lobushushu, ubunzima be-HRC45.

4. Imilo yebhloko yokuzithambisa ngokuzithambisa kunye neemfuno zikaMosaic.Kukho iintlobo ezimbini zeebhloko zokuzithambisa, icylindrical kunye noxande, ezinokuthi zibe cylindrical okanye uxande ngokuxhomekeke kwindawo ekuyo.Kungakhathaliseki ukuba imilo yayo, kufuneka ifakwe ngokukhuselekileyo ukwenzela ukuba ingawi ngexesha lokusebenza.

I-coefficient yokwandiswa komgca we-self-lubricating block malunga namaxesha angama-10 ensimbi.Ukujongana nokutshintsha kweqondo lokushisa, ukucocwa phakathi kwe-shaft kunye ne-bushing kwandisa ukusuka kwi-4-step yangaphambili ye-dynamic fit ye-metal part (D4 / DC4) ukusuka kwi-0.032 ukuya kwi-0.15 mm ukuya kwi-0.45 ukuya kwi-0.5 mm.Ibhloko ye-self-lubricating ikhupha i-0.2-0.4mm kwintsimbi ye-bushing kwelinye icala le-friction pair.Ngale ndlela, ixesha lokuqala lokuqhutywa komsebenzi wokuthwala lifakwe i-lubricated ngokupheleleyo, ngaloo ndlela ukunciphisa ukusetyenziswa kokuhanjiswa kwamandla.

Oku ngasentla kukho konke umxholo malunga nendlela yokukhetha iibheringi zokuzithambisa.Enkosi ngokuqonda kunye nenkxaso yakho!
