Planetary Roller Screw(standard type) inzira yekufambisa inosanganisa helical motion uye mafambiro epuraneti kushandura kutenderera kwescrew kuitalinear kufambaye nzungu. Planetary Roller Screws ine hunhu hwekutakura mutoro wakasimba, kusimba kwepamusoro, kurongeka kwepamusoro, kupfeka kuramba, kusagadzikana kwekuvhunduka uye hupenyu hurefu, nezvimwe, izvo zvinoshandiswa zvakanyanya muindasitiri nekudzivirira nemauto:
Kuumbwa:mapuraneti roller screws anonyanya kuumbwascrews, rollers, nzungu, mukati giya mhete, cage uye elastic retaining ring;
Motion mode:mapuraneti roller screws mubasa, iyo screw inowanzo shandiswa sekuisa simba, chete kutenderedza axis yayo yekutenderera; nut inowanzobatanidzwa nemutoro, chete pamwe chete neaxis yayo yekufamba; roller mu nati uye kufamba kwepuraneti pakati pe screw uye axial displacement ye nut inoenderana ne zero, uye nati pamwe chete nekufamba mune axial direction.
Nemapuraneti roller screw mumaindasitiri akasiyana anoenderera mberi nekudzika, mamiriro ekushandisa ayo anouyawo zvakanyanya uye zvakanyanya, kuitira kuchinjika kune akasiyana siyana ekushandisa uye mamiriro ekuisa, chimiro chefomu chiri zvakare mukusimudzira. Yakajairwa, cyclic, reverse, musiyano uye mamwe mapuraneti roller screws anoshandiswa zvakanyanya:
(1) Standard mhando: Kazhinji, screw ndiyo inhengo inoshanda uye nati ndiyo inobuda nhengo. Inogona kuzadzisa sitiroko yakakura, yakakodzera kunharaunda dzakaoma, mutoro mukuru, kukurumidza kukurumidza uye dzimwe nguva, inonyanya kushandiswa mumashandisi emuchina chaiwo, marobhoti, midziyo yemauto nemimwe minda, parizvino ndiyo inonyanya kushandiswa mhando;
(2) Inverted type: chimiro chayo chechimiro chakafanana nemhando yakajairwa, mutsauko ndewekuti haina mhete yemukati yegiya, mazino akatwasuka kumagumo ese escrew mesh nemagiya kumagumo ese e roller, uye nzungu sechikamu chinoshanda, kureba kwacho kwakakura kudarika iyo yemhando yemhando. Kazhinji kutaura, iyo nut yeinverted planetary roller screwinhengo inoshanda, screw inhengo inobuda, uye hapana axial displacement pakati pe roller ne screw, iyo inonyanya kushandiswa kune diki uye yepakati mitoro, diki sitiroko uye high-speed application scenarios, uye yakakura kwazvo. mukana ndewekuti nati yayo inogona kushandiswa semotor rotor kuti iwane yakasanganiswa dhizaini yemota uye screw kuti igadzire compact one-piece electro-mechanical actuator;
(3) Kudzokorodza mhando: Kana ichienzaniswa neyakajairwa mhando, inobvisa yemukati giya mhete uye inowedzera iyo cam ring dhizaini, ine basa rakafanana nerekudzoreredza bhora screw, kuitira kuti roller idzokere kunzvimbo yekutanga mushure mekutenderera. munzungu kwevhiki imwe chete. Maitiro ekuumbwa kwerecirculating planetary roller screwkuwedzera huwandu hwetambo dzakabatanidzwa mukubatana, saka ine kuoma kwepamusoro uye hukuru hwekuremerwa, uye inonyanya kushandiswa mumaapplication anoda kuomarara kwakanyanya, hukuru hwekuremerwa, uye kurongeka kwepamusoro, senge midziyo yekurapa, zviridzwa zvemaziso, nezvimwe minda. . Izvo zvakashata ndezvekuti iyo cam ring dhizaini inoburitsa vibration maitiro, pane dambudziko reruzha;
(4) Rudzi rwakasiyana: Kuenzaniswa nemhando yakajairika, mhete yemukati yegiya inobviswa uye hapana chikamu chegiya pane roller. Mamiriro ekuumbwa kweanosiyana mapuraneti roller screw anoita kuti zvikwanise kuwana diki lead, iyo inokodzera maapplication ane yakakura kutapurirana ratios uye yakakwirira mutoro kutakura. Zvisinei, panguva yekufamba kwayo, tambo dzichabudisa sliding phenomenon, iyo inowanzopfeka pasi pemitoro inorema, zvichiita kuti kurasikirwa kwechokwadi, kuderedzwa kuvimbika uye mamwe matambudziko.
Iyo inverted roller screw mune linear actuator
Planetary roller screw penetration inotarisirwa kuwedzera, ichitsiva chikamu chemunda webhora screws uye hydraulic transmissions:
(1) Zvichienzaniswa nekufambiswa kwebhora screws, mapuraneti roller screws ane simba rekutakura, anogona kuiswa mumamiriro akaoma uye akaomarara ekushanda, hupenyu hurefu uye zvimwe zvakanakira, zvinotarisirwa kuiswa mumunda wemichina maturusi, robotic magetsi. cylinders nezvimwe zviitiko;
(2) Zvichienderana nepuraneti roller screw precision transmission chimiro, kukurira yechinyakare hydraulic transmission mudziyo inogara kuchinjika kwezvakatipoteredza, yakaderera kuvimbika, kushandiswa kwekusagadzirisa zvakanaka uye zvimwe zvinokanganisa, zvinotarisirwa kutsiva chikamu chechiitiko hydraulic transmission mudziyo.
