Isikrufu serola yeplanethiIkhonkco leshishini liquka imathiriyeli ekrwada enyukayo kunye nonikezelo lwamacandelo, ukwenziwa kwesikrufu sesijikelezi-jikelele esiphakathi, amasimi ezicelo ezininzi asezantsi. Kwikhonkco elinyukayo, izinto ezikhethiweyo ze-screws ze-roller zeplanethi zininzi i-alloy structural steel, kunye nezinto ezikhethiweyo zamantongomane kunye ne-roller yintsimbi ye-carbon chrome enentsimbi; iindawo ziquka izikrufu, amandongomane kunye namanye amacandelo aphambili. Iimeko zesicelo esisezantsi zibandakanya uluhlu olubanzi lwamashishini, ukusuka kwiimoto, ioli kunye negesi, izixhobo zonyango ukuya kwizixhobo ze-optical, oomatshini bobunjineli, iirobhothi, i-automation kunye nesixhobo somatshini.
Izikrufu zerola zePlanethi zihlala zisetyenziswa njengeendawo ezisebenzayo zeimotoii-actuators, ezisetyenziswa kakhulu kumashishini ahlukeneyo, ngakumbi kuphapho kunye ne-aerospace kwiminyaka yakutshanje, efuna iimfuno eziphezulu ze-motor actuators ezifana nobunzima kunye nokuthambisa, njl.i actuatorIinkqubo, kwaye kufuneka zithathele ingqalelo iimfuno zezicelo zeshishini ngelixa ziqinisekisa iipropathi zoomatshini.
Uyilo kufuneka luqwalaselwe ngexesha elifanayo njengentambo kunye nokulungiswa kwezinyo, i-screw diameter encinci, inani lamazinyo e-roller teeth modulus lincinci. Uyilo lokuqwalasela ukuchithwa kweengcambu kunye nokuqinisekisa ukuba umgca ophakathi we-screw kunye ne-gear center line coincidence kunye neminye imiba. Luluphi uhlobo lwendlela yokulungisa izinyo olubalulekileyo, ukusetyenziswa ngokubanzi kwendlela yokufaka igiya, kodwa oku kuya konakalisa inxalenye yecandelo elithwele umthwalo womsonto, ukunciphisa umthamo womthwalo wenkqubo.
I-Planetary roller screws inzima ngakumbi ukudibanisa, ubunzima kukuqinisekisa ukuba imicu ye-roller ihambelana namazinyo egiya ngelixa ivumela ukuba ii-roller ezininzi zifakwe ngokulandelelana. Iindlela ezimbini zokusombulula ingxaki yokulinganisa isigaba: ukwandisa ukukhutshwa kwentambo ngeendleko zokuthwala umthwalo kunye nokusebenza kakuhle kokuhanjiswa; ukulungelelanisa indawo yokunyuka kwe-axial, efanelekileyo kwimibhobho emincinci kodwa inokubangela ukuba amazinyo e-roller akhuphe kwiringi yangaphakathi yegiya kwimeko ye-pitches enkulu.
Xa kusetyenzwa izikrufu ze-roller zeplanethi, kuba ixhomekeke kwi-rolling friction ukuhambisa amandla, kuyimfuneko ukunikela ingqalelo kwi-friction kunye nokugqoka. Ukuthambisa okufanelekileyo, umatshini ochanekileyo, kunye nokusingqongileyo okucocekileyo kubalulekile ekuphuculeni ukuthembeka kunye nobomi be-screw.
Ukuze kuhlangatyezwane nokusebenza kweplanethi ye-roller screw drive kunye neemfuno zokuchaneka, ukuze ufumane ubomi obude bokusebenza kunye nomthamo ophezulu wokuthwala umthwalo, umzila womdyarho kufuneka ube nobunzima obuthile, ngokubanzi HRC58 ~ 62, isakhiwo se-roller sincinci ngobukhulu. , kunye namazinyo adityanisiweyo owona mthwalo uphambili, ubulukhuni bayo ngokuqhelekileyo yi-HRC62~64.
Kwindawo yokusebenza yobushushu obuphezulu okanye izinto zensimbi ezingenasici ezicutshungulwa yi-PRSPRS, i-threaded raceway Kwindawo yokusebenza yobushushu obuphezulu okanye i-PRS ecutshungulwe ngezinto zetsimbi engenasici, ukuqina komphezulu we-threaded raceway HRC<58 ifanelekile.
