Planetary Roller Screws - Qhov Zoo Tshaj Plaws rau Pob Screws

Lub planetary roller ntsia hlau muab faib ua plaub hom qauv sib txawv:

Daim ntawv no ntawmplanetary roller ntsia hlauCov khoom muaj xws li: ntev threaded spindle, threaded roller, threaded txiv ntseej, bearing cap thiab hniav tes tsho. Lub axial load yog xa mus rau threaded txiv ntoo ntawm threaded arbor ntawm threaded roller. Lub kaw lus yog synchronized los ntawm cov hniav ntawm cov threaded roller thiab ob lub tes tsho hniav. Zoo ib yam li lub tawb hauv apob bearing, lub hau bearing ua kom qhov kev ncua deb ntawm cov threaded rollers ntawm lub voj voog ntawm cov ntsia hlau.

Daim ntawv no ntawm kev tsim kho ntawm planetary roller screws yog siv qhov tseem ceeb nyob txhua qhov chaw uas siab precision, repeatability thiab siab load peev xwm yuav tsum tau rau electromechanical linear drives.

Lub hom phiaj ntawm lub ntiaj teb no cov menyuam ntsia hlau muaj cov khoom siv: ntev threaded spindle, threaded roller, threaded txiv ntseej, tawb tawb thiab cam retainer. Hom planetary roller ntsia hlau no muaj cov khoom siv rov qab ua haujlwm ntawm cov tub ntxhais threaded. Nrog rau qhov no kinematics (rov qab) nws muaj peev xwm ua kom tiav planetary cov menyuam ntsia hlau txuas nrog cov hlau lead me me, kev siv xov zoo thiab muaj peev xwm thauj khoom. Qhov no kuj tso cai rau cov hlau lead me me rau ntawmntsia hlaunrog loj nominal diameters. Zoo ib yam li lub pob nyob rau hauv ib lub pob bearing, threaded roller yog tuav nyob rau hauv qhov chaw los ntawm lub tawb ntawm lub spindle ncig. Tom qab ib lub kiv puag ncig ntawm lub tawb, threaded roller yog lifted radially tawm ntawm lub ntsiab ntsia hlau xov los ntawm ib tug cam mus rau hauv ib tug so nyob rau hauv lub spindle txiv ntoo. Ib lub voj voog yog tom qab ntawd ua tiav hauv qhov chaw so los ntawm kev tig cov xov rau cov menyuam rov qab los ntawm ib lub kiv puag ncig ntawm threaded ncej.

Daim ntawv no ntawm kev tsim kho feem ntau yog siv nyob rau hauv electromechanical linear drives uas yuav tsum tau siab load nqa peev xwm nrog siab raug, repeatability thiab me me lead lengths rau cyclic roller planetary roller screws. Cov me me spindle lead tuaj yeem ua tiav qhov chaw siab heev nyob rau hauv kev cuam tshuam ntawm kev thauj khoom siab.

Daim ntawv no ntawm planetary cov menyuam ntsia hlau muaj cov khoom siv: ib tug threaded spindle nrog ib tug ntev optical axis, ib tug threaded roller, ib tug ntev threaded txiv ntseej, ib tug bearing cap thiab ib tug hniav tes tsho. RGTI nrog rov qab tsim yog rov qab version ntawm RGT. Nws muaj cov yam ntxwv zoo ib yam li RGT thiab tseem muaj lub peev xwm thauj khoom siab thiab qhov chaw raug. Nrog rau qhov kev tsim no, cov threaded roller ntawm lub spindle yog khaws cia rau hauv txoj hauj lwm kom zoo thiab synchronized los ntawm cov kabmob npog thiab iav ntug piv rau RGT. Qhov kev tsim rov qab no muaj qhov sib luag cylindrical spindle uas tsis muaj xov txuas txuas ntxiv. Cov txheej txheem no tuaj yeem raug kaw zoo los ntawm lub ntxaiv nrog lub nplhaib radial ncej sealing.

Daim ntawv no ntawm kev tsim kho feem ntau yog ua ke ua ib lub rotor hauv hollow ncej motors. Nws muaj ib qho kev sib cog lus electromechanical lwm txoj rau hydraulic thiab pneumatic lifting raws li zoo raws li rau linear drives. Nyob ntawm qhov nominal txoj kab uas hla, txiv ntseej nrog lub siab tshaj plaws xov ntev ntawm 800 mm tuaj yeem tsim rau cov neeg siv khoom tshwj xeeb.

Daim ntawv no ntawm planetary roller ntsia hlau muaj cov khoom siv: threaded spindle nrog ntev optical axis, threaded roller, ntev threaded txiv ntoo, tawb tawb thiab cam retainer. RGTRI yog qhov rov qab tsim ntawm RGTR. Nws txawv ntawm RGTR nkaus xwb nyob rau hauv hais tias lub tawb nrog threaded roller thiab zawj rau rov qab cov threaded roller yog nyob rau ntawm spindle thiab tsis nyob rau hauv cov txiv ntoo. Ua tsaug rau nws txoj haujlwm ua haujlwm ntawm cov menyuam rov qab los, RGTRI kuj tseem muaj lub suab me me thiab cov xov xov zoo dua. Smooth cylindrical spindles kuj haum rau sealing tshuab nrog rau qhov rov qab tsim.

Daim ntawv tsim kho no feem ntau yog ua ke ua ib lub rotor hauv hollow ncejlub cev muaj zog. Nws kuj tseem muab cov khoom siv hluav taws xob sib txuas rau hydraulic thiab pneumatic lifting thiab linear drives. Cov txiv ntseej threaded tuaj yeem tsim tau rau lub nominal txoj kab uas hla nrog lub siab tshaj plaws xov ntev ntawm 800 mm, nyob ntawm seb tus neeg siv khoom tsim.
