I-Planetary Roller Screws: Isithsaba soThutho oluchanekileyo oluPhezulu

I-Planetary Roller Screw(uhlobo oluqhelekileyo) yindlela yothumelo edibanisa intshukumo ye-helical kunye nesindululo seplanethi ukuguqula intshukumo ejikelezayo yesikrufu kwisijiva.intshukumo yomgcaye nut. I-Planetary Roller Screw ineempawu zomthamo oqinileyo wokuthwala umthwalo, ukuqina okuphezulu, ukuchaneka okuphezulu, ukuxhathisa ukunxiba, ukuxhathisa ukothuka kunye nobomi obude, njl., ezisetyenziswa ngokubanzi kwishishini kunye nokhuselo kunye nemimandla yomkhosi: 

Ukuqulunqwa:izikrufu zerola zeplanethi zenziwa ikakhuluizikrufu, iirola, iinati, iringi yangaphakathi yegiya, ikheji kunye ne-elastic retaining ring;

Imo yentshukumo:izikrufu ze-roller zeplanethi emsebenzini, i-screw idla ngokusetyenziswa njengegalelo lamandla, kuphela malunga ne-axis yayo yokujikeleza; i-nut idla ngokudityaniswa nomthwalo, kuphela ecaleni kwe-axis yayo yokuhamba; i-roller kwi-nut kunye nentshukumo yeplanethi phakathi kwe-screw kunye ne-axial displacement ye-nut ehambelana ne-zero, kunye ne-nut kunye nokuhamba kwi-axial direction.

Nge-planetary roller screw kumashishini ahlukeneyo aqhubeka enzulu, iimeko zesicelo sayo nazo ziza ngakumbi nangakumbi, ukuze zilungelelanise iimeko ezahlukeneyo zesicelo kunye neemeko zofakelo, isakhiwo sefom sikwaphuhliswa rhoqo. Izikrufu ezisemgangathweni, umjikelo, umva, umahluko kunye nezinye izikrufu zeplanethi zisetyenziswa ngokubanzi:

(1) Uhlobo oluqhelekileyo: Ngokubanzi, i-screw lilungu elisebenzayo kwaye i-nut lilungu lemveliso. Iyakwazi ukufezekisa i-stroke enkulu, efanelekileyo kwiindawo ezinzima, umthwalo ophezulu, isantya esiphezulu kunye nezinye iziganeko, ezisetyenziswa kakhulu kwizixhobo zomatshini ezichanekileyo, iirobhothi, izixhobo zemikhosi kunye nezinye iindawo, okwangoku luhlobo olusetyenziswa kakhulu;

2 i-nut njengenxalenye esebenzayo, ubude bayo bukhulu kakhulu kunohlobo oluqhelekileyo. Ngokuqhelekileyo, i-nut yeisikrufu somqengqelezi weplanethililungu esebenzayo, isikrufu lilungu imveliso, kwaye akukho displacement axial isihlobo phakathi roller kunye Screw, leyo ikakhulu isetyenziselwa imithwalo encinane naphakathi, imivumbo emincinci kunye neemeko zesicelo ngesantya esiphezulu, kwaye inkulu yayo imithwalo. inzuzo kukuba i-nut yayo ingasetyenziselwa njenge-motor rotor ukufezekisa uyilo oludibeneyo lwe-motor kunye ne-screw ukwenza i-compact one-piece electro-mechanical actuator;

(3) Uhlobo olujikelezayo: Xa kuthelekiswa nohlobo oluqhelekileyo, lususa umsesane wegiya yangaphakathi kwaye yongeza isakhiwo se-cam, umsebenzi wayo ufana nombuyisi we-screw's, ukwenzela ukuba i-roller ibuyele kwindawo yokuqala emva kokujikeleza. kwi nut iveki enye. Iimpawu zesakhiwo seisikrufu somqengqelezi weplanethiukwandisa inani leentambo ezibandakanyekayo ekubandakanyekeni, ngoko inokuqina okuphezulu kunye nomthamo omkhulu womthwalo, kwaye isetyenziswa ikakhulu kwizicelo ezifuna ukuqina okuphezulu, umthamo ophezulu womthwalo, kunye nokuchaneka okuphezulu, njengezixhobo zonyango, izixhobo ezichanekileyo kunye nezinye iinkalo. . Ukungalungi kukuba isakhiwo sayo se-cam ring siya kuvelisa impembelelo ye-vibration, kukho ingxaki yengxolo;

(4) Uhlobo oluhlukileyo: Xa kuthelekiswa nohlobo oluqhelekileyo, i-ring gear yangaphakathi iyasuswa kwaye akukho nxalenye yegesi kwi-roller. Iimpawu zesakhiwo se-different planetary roller screw zenza kube lula ukufumana isikhokelo esincinci, esifanelekileyo kwizicelo ezinomlinganiselo omkhulu wokuhambisa kunye nomthamo ophezulu wokuthwala umthwalo. Nangona kunjalo, ngexesha lokuhamba kwayo, imicu iya kuvelisa i-sliding phenomenon, ekulungele ukugqoka phantsi kwemithwalo enzima, ekhokelela ekulahlekelweni kokuchaneka, ukunciphisa ukuthembeka kunye nezinye iingxaki.

Isikrufu serola esijikiweyo kwi-actuator yomgca

Ukungena kwePlanet roller screw kulindeleke ukuba kwandiswe, kutshintshe indawo yebala lezikrufu zebhola kunye nokuhanjiswa kwehydraulic:

(1) Xa kuthelekiswa nokuhanjiswa kwezikrufu zebhola, izikrufu ze-roller zeplanethi zinamandla okuthwala, zinokusetyenziswa kwiimeko ezinzima kunye nezinzima zokusebenza, ubomi obude kunye nezinye iingenelo, kulindeleke ukuba zisetyenziswe kwintsimi yezixhobo zoomatshini, umbane werobhothi. iisilinda kunye nezinye iimeko;

(2) Ngokusekwe kulwakhiwo lokuhambisa isijiva seplanethi echanekileyo, ukoyisa isixhobo sokuhanjiswa kwe-hydraulic yendalo ehambelana nokusingqongileyo, ukuthembeka okuphantsi, ukusetyenziswa kogcino olubi kunye nezinye iintsilelo, kulindeleke ukuba kuthathelwe indawo indawo yesixhobo sosasazo lwe-hydraulic.
