Reducers zezindlu: ulwazi ngokubanzi kunye neempawu

Ubucukubhede - oku inzululwazi, ngaphandle apho namhlanje lee inkqubela uzobe olwenziwe ngocoselelo uluntu. Nawuphi na umatshini iqulethe iqondo elikhulu okanye elingaphantsi ukuchumisa ukuqinisekisa ukusebenza yayo yesiqhelo. Yaye abaninzi uyilo kinematic zezi yunithi ngokuqinisekileyo uya kubonakala kwisixhobo ekuthiwa izixhobo kusabela.

definition

Siza baqonde ngakumbi kule isixhobo ngokubanzi enemisebenzi ngoomatshini. Ngenxa yoko, iiseyile kusabela - yindlela equka amagiya, abhijelwe yezindlu kunye badla ngokusebenza webhate yeoli. Lithetha ukuthini igama elithi "zezindlu"? Oku kuthetha ukuba nasezierheni iintolo iiseyile zicwangciswe ngaxeshanye omnye komnye. Xa inani mechanism yokosulela inokuba enye-sigaba, isigaba ezimbini-,-ibakala ezintathu, njalo-njalo. D.

ukuqashwa

Zonke zezindlu gear olunye inceda ukunciphisa isantya kwaye ngaloo ndlela ukwandisa torque kwisalamane shaft eqhutywa kwi nomphini inkosi. Ngamanye amazwi, le gearbox kunciphisa uqina emboxo ye kwizikhondo motor.

isithunzi

reducer zezindlu unalo iingenelo zilandelayo:

• ukusebenza sezingeni eliphezulu.
• Ukukwazi ukumelana umthwalo onzima yaye phantse zero lahleko ukuze udlulise kumgama amandla enkulu.
• Ukwazi ukuba lisebenze kakuhle nokuba imithwalo non-uniform, kwakunye naliphi na inani iqala kunye nezingxi.
• Ukunqongophala self-tshixo (ngokuchasiweyo analogue worm), kwaye ke ngoko ke kunokwenzeka ukuba shaft kwemveliso ngesandla.
• Ilinganisa esiphezulu ukhuseleko.
• kwinqanaba ubushushu Low.
• A olubanzi anokukhetha mechanism ratio amagiya.

ezimbi

Reducer zezindlu single-Inqanaba (multistage ezifana) iye ethile efana:

• Kumanqanaba ingxolo ngexesha lomsebenzi.
• Ukuba ngqongqo eliphezulu amagiya, ngeke sigqibe imithwalo ezinamandla.
• Ukungabikho ukuyilungisa.

ngezigaba

Reducers zezindlu Isigaba-mabini, elinye ophambili kunye multi-Inqanaba nelungiselelo amazinyo zihlukaniswe:

• On the kusabela.
• Helical.
• Chevron.
• Nge izinyo setyhula.

Kuxhomekeka iprofayile kwamazinyo ukuze amagiya involute kunye lizilungiselela of Novikova kunye cycloid.

Isantya engabalulekanga kwentlobo iya kuba yile ilandelayo:

• -Low speed (isantya peripheral ngaphantsi kwe-3 m / s).
• Isantya Medium (isantya circumferential na iintlobo ukususela-3 ukuya kwi-15 m / s).
• Speed (circumferential isantya ubungakanani isusela kwi-15 ukuya kuma-40 m / s).
• Isantya esiphakamileyo (isantya ngaphezu kwe-40 m / s).

device

Spur nezixhobo, ukusondela yayo eboniswe ngezantsi kuqwalaselo jikelele sakhiwa:

• Izindlu.
• Imikhonto.
• Iibheringi.
• inkqubo ukuthambisa ajikeleze.

Ubuchwephetshe bokuba le iiseyile, leyo inani amancinane amazinyo, ekuthiwa nezixhobo, kunye nenani elikhulu amazinyo - wheel.

obandayo

Reducer zezindlu omnye eqongeni kunye nokufakwa multi-isigaba na lo mgaqo, oko kuxhomekeke ekubeni imithetho embalwa, oko kukuthi:

• Umphezulu bha kuba gear kufuneka ibe mpuluswa, ukuze ukuvala amathuba warping.
• coupling Kukho kufuneka-lungelelanisa ekhwele ukuya ubuninzi ku ukunciphisa imikhosi ebabusisakha kwi kwizikhondo iphela.
• Akuvunyelwe ngqo emana enkqonkqoza iziphelo imigodi njengoko oku kunokukhokelela ukusilela ngaphambi kokuba ukuthwala onenombolo.
• Retaining iibholiti obandayo ngenjongo yokuvelisa kwinqanaba ngokufanayo amathuba bezikhulule kunye nezixhobo ngexesha ukusebenza kwalo okwalandela.

Imigaqo ethuma

Reducers zezindlu Isigaba-mbini, njengoko, eneneni, nayiphi na enye gearbox kufuneka uqale umsebenzi wayo ngokusekelwe ezi mfuno:

• Iziphelo shaft ziye azabi ngokudleka okanye ukungcola.
• Basonta Screw oyile nakumsele nokumisela ukungabikho / phambi condensate.
• Iparafini kungena crankcase ngokusebenzisa icebo lokucoca entle enemingxuma ukuphumeza ukuze ecaleni amathuba ukubetha amasuntswana esirhabaxa ngaphakathi gearbox. Ngoko le lobushushu oyile kufuneka ibe ngaphantsi kweqondo 20 Celsius.
• Kunqweneleka ukuba umqulu iintolo ngesandla uze umamele umsebenzi toothing.

The main iparameters elawula ezikhethiweyo gear zezindlu kwalo ratio iimpahla kunye nokushiya izithuba.

Zezindlu Isigaba-ezimbini nezixhobo - uhlobo ixhaphakileyo nezixhobo ezisetyenziswayo ngoku (malunga 65%). Ziyafana ezi iindlela kuluhlu ukususela 8 ukuya 40 Ngaloo Kwiimeko apho kukho imfuneko engxamisekileyo ukuphucula ukusebenza ethe ntli nesezantsi isantya yeqonga isicelo kunye reducers yeqonga-high speed bifurcated.
