Kabo ena e lumella li-gear tse helical ho laola meroalo e meholo le ho atolosa bophelo ba tsona ba ts'ebeletso.

Mathata a Helical Gear

Axial Thrust

Mekhoa ea li-gear tsa helical e hlahisa axial thrust hobane meno a tsona a sehiloe ka sekhutlo. Matla ana a sutumelletsa li-gear ho latela axis ea potoloho. Axial thrust ea eketseha ha sekhutlo sa helix se ntse se phahama. Ho fapana le li-spur gear, tse nang le meno a otlolohileng 'me li sa hlahise axial thrust, meralo ea li-gear tsa helical e hloka taolo e hlokolosi ea matla ana.

Tšusumetso ea axial e ama likarolo tse 'maloa tsa moralo oa sistimi ea lisebelisoa:

●E ama khetho ea libere le ho hokahanya li-gear.

●Tsamaiso e nepahetseng e thibela ho se tsamaisane hantle ha didiriswa le ho senyeha ho hoholo.

●Ho sutumelletsa ho feteletseng ha axial ho ka baka lerata, ho thothomela, le ho hloleha ha bearing pele ho nako.

Litsamaiso tsa li-helical gear li kenya matla a radial le axial holim'a li-bearing, e leng se etsang hore moralo o be thata le ho feta. Baenjiniere ba tlameha ho khetha li-bearing tse ka sebetsanang le meroalo ena e kopaneng ho netefatsa ts'ebetso e tšepahalang.

Litšenyehelo tse Phahameng tsa Tlhahiso

Ho etsa lisebelisoa tsa helical ho hloka lits'ebetso tse tsoetseng pele ho feta li-spur gear. Meno a nang le sekhutlo a hloka lisebelisoa tse khethehileng le lisebelisoa tse nepahetseng haholo. Ho rarahana hona ho lebisa litšenyehelong tse phahameng tsa tlhahiso.

Mabaka a 'maloa a tlatsetsa keketsehong ea litšenyehelo:

1. Mahlakore a meno a na le sekhutlo se sekametseng, e leng se etsang hore ts'ebetso e be thata le ho feta.

2. Ho hlokahala lisebelisoa tse khethehileng le mechini e nepahetseng haholo.

3. Litsamaiso tsa lisebelisoa tsa Helical hangata li sebelisa thepa ea boleng bo holimo le mekhoa e khethehileng ea ho phekola mocheso.

4.Potoloho ea tlhahiso e telele, ka mehato e mengata le litlhoko tsa tekheniki.

Mabaka ana a etsa hore lisebelisoa tsa helical e be khetho e turang haholo bakeng sa lits'ebetso tse ngata.

Monyetla oa Tahlehelo ea Motlakase

Litsamaiso tsa li-gear tsa Helical li sebetsa hantle, empa li ka lahleheloa ke matla ka lebaka la khohlano le ho sutumelletsa ka axial. Bokgoni ba li-gear tsa helical hangata bo tloha ho 98% ho isa ho 99%. Leha ho le joalo, tlhoko ea li-bearing tsa ho sutumelletsa ho laola matla a axial e ka hlahisa khohlano e eketsehileng, e fokotsang bokhoni ka kakaretso.

Tahlehelo ea motlakase e bakoa haholo-holo ke khohlano ea meno le ho sisinyeha ha setlolo. Tahlehelo ena e ka ama ts'ebetso ea sistimi ea li-gear, haholo-holo lits'ebetsong tse potlakileng kapa tse boima.

Ho Hlokahala Li-Bearings tse Ikhethang

Litsamaiso tsa li-gear tsa Helical li hloka li-bearing tse khethehileng ho sebetsana le meroalo ea axial e hlahisoang ke meno a sekametseng. Li-bearing tsa li-roller tse nang le tapered li sebelisoa hangata hobane li ka tšehetsa matla a radial le a axial. Li-bearing tsena hangata li hlophisitsoe ka bobeli ho loantša ho sutumelletsa ka mahlakoreng ka bobeli.

Meralo e ikgethang ya di-bearing e eketsa ho rarahana le ditjeo tsa sistimi ya di-gear. Baenjiniere ba tlameha ho kgetha le ho kenya di-bearing tsena ka hloko ho netefatsa hore ho arolelanwa mojaro hantle le taolo e nepahetseng ya axial.

Tlhokomelo e Eketsehileng

Litsamaiso tsa li-gear tsa helical hangata ha li hloke tlhokomelo e ngata khafetsa ho feta li-gear tsa spur hobane ho kenella ha tsona butle-butle ho fokotsa ho tsofala. Leha ho le joalo, mathata a tlhokomelo a ntse a ka hlaha, haholo-holo haeba sistimi e sa laoloe hantle.

Mathata a tloaelehileng a tlhokomelo a kenyelletsa ho tsofala ha li-gear, tšenyo ea li-bearing, mathata a ho tlotsa, le ho kenngoa ho sa lokelang. Tlhahlobo ea kamehla le ho tlotsa ka nepo ho thusa ho thibela mathata ana le ho lelefatsa bophelo ba sistimi ea li-gear.

Keletso:Tlhokomelo ea kamehla le ho kenya ka hloko lia hlokahala bakeng sa ts'ebetso e tšepahalang ea lisebelisoa tsa helical.

Ho Tšoaneleha ha Kopo

Nako ea ho Sebelisa Li-Helical Gears

Li-gear tsa helical li sebetsa hantle maemong ao ts'ebetso e boreleli le e khutsitseng e leng ea bohlokoa. Liindasteri tse ngata li itšetleha ka li-gear tsena bakeng sa bokhoni ba tsona ba ho sebetsana le meroalo e phahameng le ho fokotsa ho thothomela. Hangata baenjiniere ba khetha li-gear tsa helical bakeng sa mechini e sebetsang lihora tse telele kapa e hlokang ts'ebetso e tšepahalang.

Lintlha tsa bohlokoa tseo u lokelang ho li nahana li kenyelletsa ntlafatso ea boemo ba meno, khetho ea thepa le lipalo tsa boenjiniere. Ho khetha thepa e nepahetseng le kalafo ea mocheso ho ntlafatsa bophelo ba lisebelisoa le ts'epo. Lisebelisoa tse tsoetseng pele joalo ka tlhahlobo ea likarolo tse lekanyelitsoeng li thusa ho etsisa khatello ea maikutlo le mokhathala, li tataisa likhetho tse betere tsa moralo.

Keletso:Li-gear tse chitja li loketse hantle ha o hloka phetiso e boreleli ea matla, torque e phahameng, le lerata le fokotsehileng.

Nako ea ho Khetha Li-Gear tse Ling

Li-gear tsa Spur kapa li-gear tsa bevel e ka ba likhetho tse betere maemong a itseng. Li-gear tsena li loketse lits'ebetso moo litšenyehelo, sebaka, kapa tlhokomelo e leng lintho tsa bohlokoa.

●Lebelo la ts'ebetso le ntse le le ka tlase ho 1,000 RPM

●Lerata le ho thothomela ke lintho tse amohelehang tse fapaneng

●Lithibelo tsa tekanyetso ke tsona tse ka sehloohong tse bakang (poloko ea litšenyehelo ea 30-40%)

●Bokgoni bo phahameng ka ho fetisisa (99%+) boa hlokahala bakeng sa lits'ebetso tse amang matla haholo

●Sebaka sa axial se lekanyelitsoe mme di-bearing tsa thrust ha di kgone ho kenngwa

● Tlhokomelo e bonolo e nang le di-bearing tse tloaelehileng tsa radial e khethoa

Li-gear tsa worm li fana ka melemo ho li-hoist le lifti hobane li ka its'oara ka botsona 'me tsa fana ka phokotso e kholo ea lebelo. Li-gear tsa helical li fana ka katleho e phahameng le tlhokomelo e bonolo ha li bapisoa le li-gear tsa worm, empa li-gear tsa worm li sebetsa ka khutso tlas'a meroalo e boima.

Ho khetha mofuta o nepahetseng oa gear ho latela sebopeho sa shaft, litlhoko tsa torque, potoloho ea mosebetsi, meeli ea sebaka le lintho tse tlang pele ka katleho.

Li-gear tsa helical li fana ka ts'ebetso e boreleli le bokhoni bo phahameng ba ho jara, empa li hloka li-bearing tse khethehileng 'me li bitsa chelete e ngata. Baenjiniere ba lokela ho sekaseka lintlha tsena:

● Litlhoko tsa kopo joalo ka lebelo le torque

●Bokgoni ba ho jara le bokgoni

●Meeli ea sebaka le moralo

●Matla a thepa
