helical iav intruduction thiab kev faib tawm
Lub zog Helical tsis zoo ib yam li cov sprial zog. Nws yuav tsum tau hais tias cov iav helical yog hom meshing ntawm ob lub zog helical, uas tau paub qhov txawv los ntawm cov lus qhia sib txawv hauv uas lawv kis cov rog hauv qhov chaw. Cov cuab yeej zoo tib yam spurles lub suab sib txuas rau tib lub sijhawm ua ke raws qhov dav ntawm cov hniav, uas ua rau muaj suab nrov tshee tshee thiab tsis xa khoom tsis ruaj khov.
Tsim qauv tso cai
Txoj kev tsim ntawm cov pa roj hmab helical cylindrical hniav yog muaj nyob hauv daim duab 8.25. 
Hauv daim duab 8.25, lub cim lub cim sab tau hloov mus rau lub hauv paus kheej kheej, thiab cov kab cim tsim lub kaum sab xis βb nrog lub axis.
Thaum lub kaum sab xis βb = 0, cov hniav ntawm lub pob iav spur yog tsim.
Geometric Cov Khoom Ntawm Helical Cylindrical Zog
Qhov kawg ntawm tus hniav profile ntawm cov iav helical cylindrical yog qhov muaj tseeb kev tsis txaus ntseeg, thiab cov hniav txha hniav laus yog tus neeg tsis raug, raws li qhia hauv daim duab 8.27. Nws kawg lub ntsej muag thiab lub ntsej muag lub ntsej muag tsis sib txawv.
(1) Lub kaum sab xis Helix ntawm qhov cylindrical nto ntawm lub hauv paus thiab lub kaum sab xis helix ntawm lub voj voog kawm tiav
(2) Lub ntsej muag zoo ib txwm modulus mn thiab kawg lub ntsej muag modulus mt ntawm lub zog helical spur
(3) Qhov yooj yim lub kaum ntse ntse lub kaum thiab lub ntsej muag siab lub kaum sab xis ntawm helical spur iav
(4) Hniav qhov siab coefficient thiab cag qhov siab coefficient ntawm helical iav
(5) Helix kaum sab xis ntawm sab cylindrical sab ntawm lub hauv paus thiab lub kaum sab xis Helix ntawm lub voj voog kawm tiav
(6) Kho cov lus meshing ntawm cov pa roj carbon helical
Cov kev sib raug zoo ntawm tus qauv, siab kaum thiab helix kaum sab xis ntawm ib khub ntawm helical cylindrical zog yog
Tshaj sib npaug ntawm cov iav helical spur
Ua Si ntawm Helical Cylindrical Iav Transmission
Lub sab laug sab saud yog lub meshing nto ntawm spur iav tsav, thiab tus qauv qis sab laug yog lub meshing nto ntawm helical gear tsav. B2B2 hauv daim duab sawv cev rau txoj hauj lwm qhov uas khub ntawm lub zog nkag mus rau txoj haujlwm meshing, thiab B1B1 sawv cev rau txoj hauj lwm uas cov iav tawm ntawm meshing.
Cov yam ntxwv ntawm Helical Cylindrical Gear Kis
Qhov zoo:
1) Cov cwj pwm zoo meshing,
2) Loj xwm txheej
3) Cov tsawg kawg ntawm cov hniav uas tsis ua rau kev txiav hniav yog tsawg dua li ntawm cov hniav ncaj.
Qhov tsis zoo: Lub zog quab yuam tsim tawm thaum ua haujlwm.
Staggered ncej helical iav tsav
Thaum ob lub iav helical muaj tib lub qauv qub, qhov ntsuas lub siab kom zoo ib yam yog qhov sib npaug, thiab helix cov ces kaum tsis sib npaug, lawv ua tus tsav staggered tsav. Lawv cov hniav ua hauj lwm yog nyob rau hauv kev sib cuag.
(1) Qhov chaw deb a = (d1 + d2) / 2 = mn (Z1 / cosβ1 + Z2 / cosβ2) / 2
(2) Kev hloov pauv sib piv ntawm i12 = ω1 / ω2 = Z2 / Z1 = (d2 / mt2) / (d1 / mt1) = d2cos β2 / mn2 / (d1cos β1 / mn1) = d2 cos β2 / (d1 cos β1)
