MOLA 01 · ROBOTIKI E MOLELANE : Phepelo ea axis ea kopano ea Cobot

Moetsi oa liroboto ea kopanetsoeng o kopantseng likarolo tse nepahetseng tsa phokotso ea lisebelisoa tsa polanete (karo-karolelano ea 80: 1, backlash<2 arcmin) into each of six joint axes. The coaxial output design kept arm geometry compact while delivering the high holding torque needed for safe human-collaborative tasks. Repeatability improved to ±0.03 mm, and the reduction in motor sizing lowered overall arm weight by 18%, directly improving payload-to-weight ratio across assembly and pick-and-place lines.

CASE 02 · FILM EXTRUSION : Extruder screw drive

Mohala oa polasetiki oa extrusion ea filimi o ile oa nkela koloi ea oona sebaka sa liboko sebaka ka-gearbox ea ho fokotsa lipolanete tsa mekhahlelo e 'meli (karolelano 56:1, 97%). Phetoho e felisitse tahlehelo ea mocheso e bakileng ho se lumellane ha viscosity nakong ea nako e telele ea tlhahiso. Ho tsitsa ha torque ho ntlafetse ka mokhoa o leka-lekaneng, litheko tsa masela li theohile ka 12%, 'me moralo o tiisitsoeng, oa mafura{7}}o fokolitse nako ea ho lokisoa ho tloha khoeli le khoeli ho isa ho selemo - ho fokotsa nako ea ho fokotsa nako le ho fana ka litšenyehelo ka lenaneo le tsoelang pele la tlhahiso ea lihora tse 24.

Lipotso mabapi le phokotso ea lisebelisoa tsa lipolanete

Ke eng e etsang hore phokotso ea lisebelisoa tsa polanete e sebetse hantle ho feta lisebelisoa tsa liboko?

Phokotso ea lisebelisoa tsa polanete e fihlela katleho ea 95-98% hobane matla a fetisoa ka ho kopana le mesh ea gear e nang le likhohlano tse fokolang tse thellang. Litsamaiso tsa Worm li itšetlehile ka ho thella pakeng tsa seboko le lebili, e leng se felisang matla kaha mocheso - o ka theoha ka tlase ho 50% ka tekanyo e phahameng. Bakeng sa-ts'ebetso e tsoelang pele, ho baballa matla ho tloha ho fetohela ho sistimi ea lipolanete ho bohlokoa ho feta nako ea bophelo ba sesebelisoa.

Ke karo-karolelano efe ea phokotso eo ke lokelang ho e khetha bakeng sa ts'ebeliso ea koloi ea ka ea servo?

Tekanyo e nepahetseng ea tekanyo e tsamaisanang le inertia, lebelo le hlokahalang la tlhahiso, le tlhokeho ea torque e holimo. Molao-kakaretso: karolelano ea lisebelisoa e lokela ho lekana le lisekoere tsa moroalo-ho{2}}karolelano ea motlakase. Bongata ba lilepe{4} tse tsamaisoang ke liroboto le CNC li sebelisa likarohanyo lipakeng tsa 10:1 le 80:1. Moenjineri oa koloi kapa sesebelisoa sa boholo ba moetsi oa li-gearbox se lokela ho netefatsa khetho ea ho qetela ka data ea 'nete ea potoloho ea mojaro.

Ho khutlela morao ho lekanyetsoa joang yuniti ea phokotso ea lisebelisoa tsa polanete?

Backlash e lekantsoe ka arcminnutes (arcmin) ho shaft ea tlhahiso ka kenyelletso e ts'oaretsoeng e eme. Torque e sebelisoa ka nqa e le 'ngoe ho beha likere, ebe e khutlisetsoa morao - ha torque e tsamaea pele torque e fetisoa ke boleng ba backlash. Lihlopha tse tloaelehileng tsa indasteri li tsamaisa 5-15 arcmin; ho nepahala-lihlopha tsa lipolanete li fihlelleha<3 arcmin, suitable for positioning axes in robotics and multi-axis machining centers.

Na yuniti ea phokotso ea lisebelisoa tsa lipolanete e ka sebelisoa maemong a tjaro ea mojaro?

Ee. Ho fapana le lisebelisoa tse fokotsang liboko, boholo ba lipolanete ha li itsoele-ka hona, ho hlokahala brake kapa torque ea servo ho boloka boemo bo otlolohileng ha enjene e tima-ea matla. Kamehla netefatsa lintlha tsa boemo ba moetsi oa li-gearbox - kabo ea ho tlotsa oli le litekanyo tsa ho roala pele{5}li ka fapana ho ea ka litloaelo.

Bophelo bo tloaelehileng ba tšebeletso ea lebokose la li-gearbox tsa phokotso ea lipolanete ke bofe?

Ha e le boholo bo nepahetseng le ho hlokomeloa, yuniti ea phokotso ea lisebelisoa tsa lipolanete tsa boleng hangata e fihlella lihora tse sebetsang tsa 20,000-30,000 (L10 e behang bophelo). Bophelo ba tšebeletso bo itšetlehile ka ntlha ea mojaro, mocheso o potolohileng, boemo ba ho lubrication, le hore na yuniti e sebetsa ka har'a moeli oa eona o lekantsoeng oa mocheso. Mafura{7}mofuta a pakiloeng a tiisitsoeng ha a lokisoe{8}mahala bophelong ba ona; oli{9}}libaka tsa ho hlapa li hloka hore oli e fetoloe lihora tse ling le tse ling tse 3,000–5,000.
