IiPlanetary Roller Screws – Eyona ndlela igqwesileyo kwizikrufu zeBhola

I-screw roller yeplanethi yohlulwe kwiifom ezine ezahlukeneyo zesakhiwo:

◆IlungisiweRngaphezuluTypeNut MintoType

Le fomu yeiplanethi roller screwiqulathe amacandelo: intambo yokuphotha ephothiweyo, i-roller ephothiweyo, i-nut ephothiweyo, ikepusi yokuthwala kunye nomkhono wezinyo. Umthwalo we-axial udluliselwa kwi-nut edibeneyo nge-arbor ene-threaded ye-roller ene-threaded. Inkqubo ilungelelaniswa ngamazinyo kwi-roller ene-threaded kunye nemikhono yamazinyo amabini. Iyafana nekheji kwi aukuqhamisa ibhola, i-cap yokuthwala iqinisekisa umgama phakathi kwee-roller ezifakwe kwi-threaded kwi-circumference of screw.

Olu hlobo lolwakhiwo lwezikrufu ze-roller zeplanethi lusetyenziswa ngokuyimfuneko naphi na apho ukuchaneka okuphezulu, ukuphindaphinda kunye nomthamo omkhulu womthwalo ofunekayo kwii-electromechanical linear drives.

Olu hlobo lwesijija seplanethi ye-roller lubandakanya amacandelo: i-spindle emide enentambo, i-threaded roller, i-threaded nut, i-cage cage kunye ne-cam retainer. Olu hlobo lwe-screw roller yeplanethi inomsebenzi wokubuyisela oomatshini we-roller ene-threaded. Ngale kinematics (ukubuya) kunokwenzeka ukufezekisa i-planetary roller screw couplings kunye nemigama ekhokelayo encinci kakhulu, ukwakhiwa kwentambo eqinile kunye nomthamo omkhulu womthwalo. Oku kukwavumela imigama ekhokelayo emincinci kwiizikrufukunye needayamitha ezinkulu ezinokuthi. Ngokufana nebhola kwi-ball bearing, i-threaded roller ibanjwe kwindawo yekheji kwi-spindle circumference. Emva kojiko-jikelezo olunye lwekheji, irola ephothiweyo inyuswa ngokujikelezayo ngaphandle komsonto oyintloko we-screw ngekam ukuya kwindawo yokuphumla kwi-spindle nut. Umjikelo uyafezekiswa kolu khefu ngokujikelezisa irola ephothiweyo ngasemva nge revolution enye kwishafti enemisonto.

Olu hlobo lolwakhiwo luqhele ukusetyenziswa kwi-electromechanical linear drives ezifuna umthamo ophezulu wokuthwala umthwalo ngokuchaneka okuphezulu, ukuphinda-phinda kunye nobude obuncinci bokukhokela kwi-cyclic roller planetary roller screws. I-spindle encinci ehamba phambili inokufezekisa ukuchaneka okuphezulu kakhulu kokumisa phantsi kweempembelelo zemithwalo ephezulu.

Olu hlobo lwe-screw roller planetary luqukethe amacandelo: i-spindle ephothiweyo kunye ne-axis ye-optical ende, i-roller ene-threaded, i-nut ende enentambo, i-cap yokuthwala kunye nomkhono wezinyo. I-RGTI enoyilo olubuyela umva luguqulelo olungemva lwe RGT. Ngokusisiseko ineempawu ezifanayo ne-RGT kwaye inomthamo ophezulu womthwalo kunye nokuchaneka kwendawo. Ngolu yilo, i-roller ene-threaded kwi-spindle igcinwa kwindawo efanelekileyo kwaye ihambelaniswe nge-bearing cover kunye ne-gear rim xa kuthelekiswa ne-RGT. Olu yilo olubuyela umva lune-spindle ye-cylindrical egudileyo ngaphandle kweprofayili yentambo eqhubekayo. Le nkqubo ke ngoko inokutywinwa kakuhle ngokusonta ngeringi yokutywina ye-radial shaft.

Olu hlobo lolwakhiwo ludityaniswe ikakhulu njenge-rotor kwiinjini ze-shaft ezingenanto. Ibonelela ngenye indlela ye-electromechanical ecwengileyo yokunyuswa kwamanzi kunye ne-pneumatic kunye nokuhamba ngemigca. Ngokuxhomekeke kwidayamitha yesiqhelo, amandongomane anobude bomsonto obuninzi obungama-800 mm anokwenziwa kuqwalaselo oluthe ngqo lwabathengi.

Olu hlobo lwesikrufu seplanethi ye-roller lubandakanya amacandelo: i-spindle ephothiweyo ene-axis e-optical ende, i-roller ephothiweyo, i-nut ephothiweyo ende, ikheji yekheji kunye ne-cam retainer. I-RGTRI luyilo olungemva lwe-RGTR. Ihluke kwi-RGTR kuphela ukuba ikheji ene-threaded roller kunye ne-groove yokubuyisela i-roller ene-threaded ibekwe kwi-spindle kwaye ingekho kwi-nut. Enkosi kumgaqo wayo osebenzayo wokubuyiswa kwe-roller, i-RGTRI ikwabonisa i-pitch encinci kunye neprofayili yomsonto owomeleleyo. I-Smooth cylindrical spindles nayo ifanelekile kwiinkqubo zokutywinwa ngolu yilo oluphambeneyo.

Le fomu yokwakha idityaniswe ikakhulu njenge-rotor kwi-shaft engenantoiinjini. Ikwabonelela ngenye indlela ye-electromechanical edibeneyo yokunyusa i-hydraulic kunye ne-pneumatic kunye ne-linear drives. Amantongomane anemisonto anokwenziwa abe nobukhulu obungangemisonto ye-800 mm, kuxhomekeke kulwakhiwo lomthengi.
