Cov yam ntxwv ntawm cov reducer - iav, ncej, thiab cov kabmob sib xyaw

Kev sib xyaw ntawm cov iav, ncej, thiab bearings
The small gear is integrated with the shaft and is called a gear shaft. This structure is used when the diameter of the gear is not closely related to the diameter of the shaft. If the diameter of the shaft is d and the diameter of the gear tooth root circle is df, then when df-d ≤ 6-7mn, this structure should be used. When df-d>6-7mn, ib qho qauv uas lub iav thiab ncej tau muab faib ua ob ntu yog saws, xws li cov ncej qis thiab lub iav loj. Nyob rau lub sijhawm no, lub iav txuas nrog lub voj voog ncig lub tiaj tiaj tus yuam sij ntawm lub ncej, thiab cov khoom ntawm lub ncej yog axially tsau siv lub xub pwg, lub tes tsho, thiab cov kabmob npog. Ob lub shafts txais kev sib sib zog nqus groove pob bearings. Qhov kev sib xyaw no yog siv los tiv thaiv radial loads thiab tsis
Cov ntaub ntawv loj axial load. Thaum lub axial load loj, ib qho kev sib txuas ntawm angular contact pob bearings, tapered roller bearings, los yog sib sib zog nqus groove pob bearings thiab thrust bearings yuav tsum tau siv. Cov bearings yog lubricated los ntawm cov roj nyias nyias splashed thaum lub iav tig. Lub lubricating roj los ntawm cov roj pas dej ua ke nyob rau hauv lub thawv lub rooj zaum yog splashed tawm los ntawm lub rotating iav thiab splashed mus rau lub puab phab ntsa ntawm lub thawv cover. Nws ntws raws phab ntsa sab hauv mus rau qhov zawj ntawm lub npov saum npoo thiab tom qab ntawd ntws mus rau hauv cov kabmob los ntawm cov roj taw qhia zawj. Thaum immersed nyob rau hauv cov roj, lub circumferential ceev ntawm lub iav υ Tsawg tshaj los yog sib npaug ntawm qhov ceev ntawm 2m / s, lubricating roj yuav tsum tau siv los lubricate cov bearings. Txhawm rau kom tsis txhob muaj peev xwm ntawm cov roj nyias nyias ntxuav tawm cov roj lubricating, cov roj tuav cov nplhaib tuaj yeem siv los cais lawv. Txhawm rau tiv thaiv kom tsis txhob poob ntawm cov roj lubricating thiab nkag mus ntawm cov plua plav sab nraud rau hauv lub thawv, cov khoom sib khi yog ntsia nruab nrab ntawm cov kabmob kawg npog thiab cov ncej txuas ntxiv.
