Mechanics yog raws nraim txoj kev tshawb fawb yam tsis muaj kev ruaj ntseg kev vam meej ntawm noob neej niaj hnub no tsuas yog xav tsis thoob. Txhua lub tshuab muaj, rau ib qib lossis lwm qhov, cov txheej txheem uas ua kom nws ua haujlwm zoo. Thiab nyob rau hauv ntau lub kinematic daim duab ntawm cov units, ib tug ntaus ntawv hu ua ib tug cylindrical gearbox yeej muaj npe.

Definition

Cia peb saib kom ze rau ntawm cov cuab yeej siv tshuab thoob plaws ntiaj teb no. Yog li, lub cylindrical gearbox yog ib lub tshuab uas muaj lub zog, nyob rau hauv ib lub vaj tse thiab feem ntau ua haujlwm hauv cov roj da dej. Dab tsi yog txhais los ntawm "cylindrical"? Qhov no txhais tau hais tias cov axes ntawm lub gearbox shafts yog parallel rau ib leeg. Raws li tus naj npawb ntawm lub zog, lub tshuab tuaj yeem yog ib-theem, ob-theem, peb-theem, thiab lwm yam.

Destination

Txhua txhua lub cylindrical gearbox feem ntau ua haujlwm kom txo tau qhov ceev thiab, raws li, nce lub zog ntawm lub zog tsav piv rau cov ncej tsav tsheb. Nyob rau hauv lwm yam lus, lub gearbox txo lub angular tshaj tawm ntawm lub cev muaj zog ncej.

Nyob zoo ib tsoom niam txiv kwv tij neej tsas sawv daws.

Reducercylindrical muaj qhov zoo hauv qab no tsis tuaj yeem lees paub:

• Kev ua haujlwm siab heev.
• Lub peev xwm tiv taus cov khoom hnyav thiab tib lub sijhawm xa cov hwj chim loj hla qhov deb nrog yuav luag xoom poob.
• Lub peev xwm ua haujlwm tau zoo txawm tias nyob rau hauv qhov tsis sib xws, nrog rau txhua tus pib thiab nres.
• Tsis muaj qhov nres ntawm tus kheej (tsis zoo li worm analogues), thiab yog li nws muaj peev xwm tig lub tso zis ncej los ntawm tes.
• Qhov taw qhia siab tshaj plaws ntawm kev ntseeg.
• Tsawg cua sov.
• Kev xaiv dav ntawm cov txheej txheem los ntawm iav piv.

Neegative qualities

Ib-theem cylindrical gearbox (nrog rau ntau theem ib) muaj qhov tsis zoo hauv qab no:

• Ntau lub suab nrov thaum lub sijhawm ua haujlwm.
• High nruj ntawm lub zog, uas tsis tso cai kom them nyiaj rau cov khoom hnyav.
• Tsis muaj kev thim rov qab.

Kev faib tawm

Lub tog raj kheej ob-theem, ib-theem thiab ntau-theem iav tau muab faib los ntawm kev npaj cov hniav:

• Txoj hniav ncaj.
• Helical.
• Chevron.
• Nrog cov hniav ncig.

Nyob ntawm qhov profile ntawm cov hniav, gearboxes tuaj yeem cuam tshuam nrog Novikov gearing thiab cycloidal.

Qhov sib txawv ntawm qhov nrawm nrawm yuav ua raws li hauv qab no:

• Slow ceev (peripheral ceev tsis tshaj 3 m/s).
• Nruab nrab-ceev (peripheral ceev li ntawm 3 txog 15 m / s).
• High-speed (peripheral speed ranges ntawm 15 mus rau 40 m / s).
• Ceev ceev (dhau 40 m/s).

Device

Lub helical gearbox, daim duab uas tau qhia hauv qab no, hauv kev teeb tsa dav dav suav nrog:

• Cas.
• Ntxhais.
• Bearings.
• Lubrication systems.

Hauv kev siv tshuab, lub iav log uas muaj cov hniav me me hu ua iav, thiab muaj cov hniav ntau, lub log.

Installation

Ib theem thiab ntau theem helical gearboxes muaj tib lub hauv paus ntsiab lus, uas muaj nyob rau hauv kev soj ntsuam ntau txoj cai, uas yog:

• Lub hauv paus nto rau lub gearbox yuav tsum tiaj tus raws li qhov ua tau txhawm rau txhawm rau txhawm rau txhawm rau cuam tshuam.
• Nws yog ib qho tseem ceeb kom ua raws cov mounted couplings kom txo tau cov radial rog ntawm qhov kawg ntawm cov ncej.
• Nws yog txwv tsis pub ntaus qhov kawg ntawm cov ncej, vim qhov no yuav ua rau ua tsis tiav ntxov ntawm cov kabmob dov.
• Txhim kho cov bolts sib npaug txhawm rau txhawm rau txhawm rau txhawm rau txo qis lub gearbox thaum nws ua haujlwm tom ntej.

Txoj cai lij choj

Ib ob-theem cylindrical gearbox, zoo li, qhov tseeb, lwm yam gearbox, yuav tsum pib nwsua haujlwm raws li cov cai no:

• Ncej kawg yog ntxuav los ntawm corrosion lossis av.
• Unscrew cov roj ntws cov ntsia hlau thiab txiav txim siab qhov tsis tuaj / muaj cov condensate.
• Sau cov roj rau hauv lub crankcase los ntawm lub lim dej zoo txhawm rau txhawm rau tshem tawm qhov ua tau ntawm cov khoom abrasive nkag mus rau hauv lub gearbox. Nyob rau tib lub sijhawm, qhov kub ntawm cov roj no yuav tsum tsis txhob qis dua 20 degrees Celsius.
• Nws kuj yog ib qho tseem ceeb kom scroll lub shafts los ntawm tes thiab mloog lub lag luam ntawm gearing.

Qhov tseem ceeb tsis zoo los txiav txim siab thaum xaiv lub spur gearbox yog nws cov iav piv thiab qhov chaw nyob deb.

Cylindrical ob-theem gearbox yog feem ntau version ntawm gearboxes siv tam sim no (kwv yees 65%). Cov iav sib piv ntawm cov txheej txheem no txawv ntawm 8 mus rau 40. Nyob rau hauv cov xwm txheej uas yuav tsum tau ceev nrooj los txhim kho kev ua haujlwm ntawm cov theem qis-ceev, gearboxes nrog bifurcated high-speed theem yog siv.
