1. Tus naj npawb ntawm cov hniav Z Tag nrho cov hniav ntawm aiav.
2, modulus m Cov khoom ntawm cov hniav nyob deb thiab tus naj npawb ntawm cov hniav yog sib npaug rau lub voj voog ntawm lub voj voog, uas yog, pz = πd,

qhov twg z yog tus lej ntuj thiab π yog tus lej irrational. Nyob rau hauv thiaj li yuav d mus rau rational, tus mob uas p / π yog rational yog hu ua modulus. Nws yog: m = p / π
3, txoj kab uas hla ntawm lub voj voog indexing d cov hniav loj ntawm lub iav yog txiav txim siab raws li lub voj voog no d = mz luam tag nrho cov ntawv 24, txoj kab uas hla ntawm lub voj voog saum toj d. Thiab txoj kab uas hla ntawm lub hauv paus lub voj voog de puv npo nyeem los ntawm kev xam cov mis ntawm lub crest qhov siab thiab lub hauv paus qhov siab, cov qauv ntawm cov qauv ntawm lub crest voj voog txoj kab uas hla thiab lub hauv paus voj voog txoj kab uas hla yuav muab tau:
d.=d+2h.=mz+2m=m(z+2)

Qhov ntau dua qhov modulus ntawm lub log, qhov siab dua thiab tuab ntawm cov hniav, yog tias tus naj npawb ntawm cov hniav ntawm cov

iavyog qhov tseeb, qhov loj dua radial loj ntawm lub log. Modular series standards are formulated according to the requirements of design, manufacturing and inspection. Rau lub zog nrog cov hniav tsis ncaj, lub modulus muaj qhov sib txawv ntawm qhov qub modulus mn, qhov kawg modulus ms thiab axial modulus mx, uas yog raws li qhov sib piv ntawm lawv cov suab (ib txwm suab, kawg suab thiab axial suab) rau PI, thiab tseem nyob hauv millimeters. For bevel gear, the module has the big end module me, the average module mm and the small end module m1. For the tool, there is the corresponding tool modulus mo and so on. Standard modules yog dav siv. Nyob rau hauv lub metric iav tsav, cab tsav, synchronous iav siv tsav thiab ratchet, iav coupling, spline thiab lwm yam, tus qauv modulus yog qhov yooj yim parameter. It plays a basic parameter role in the design, manufacture and maintenance of the above parts

1) Modulus qhia qhov loj ntawm cov hniav. R-module yog qhov piv ntawm lub suab ntawm lub voj voog sib faib rau PI (π), qhia hauv millimeters (mm). Ntxiv rau cov qauv, peb muaj Diametral pitch (CP) thiab DP (Diametral pitch) los piav txog qhov loj ntawm cov hniav. Lub diametral pitch yog qhov ntev ntawm qhov sib faib arc ntawm qhov sib npaug ntawm ob cov hniav uas nyob ib sab.

2) "Index voj voog txoj kab uas hla" yog dab tsi? Index lub voj voog txoj kab uas hla yog siv txoj kab uas hla ntawm lubiav. Ob lub ntsiab tseem ceeb uas txiav txim siab qhov loj ntawm lub iav yog cov modulus thiab tus naj npawb ntawm cov hniav, thiab txoj kab uas hla ntawm lub voj voog sib faib yog sib npaug ntawm cov khoom ntawm cov hniav thiab cov modulus (lub ntsej muag kawg).
3) "Lub kaum sab xis siab" yog dab tsi? Lub kaum sab xis ntawm cov kab radial ntawm kev sib tshuam ntawm cov hniav thiab cov hniav zoo li tangent ntawm qhov taw tes yog hu ua lub siab lub kaum sab xis ntawm lub voj voog siv. Feem ntau hais lus, lub kaum sab xis yog hais txog lub siab lub kaum sab xis ntawm lub voj voog indexing. Qhov feem ntau siv lub kaum sab xis yog 20 °; Txawm li cas los xij, cov iav nrog lub kaum ntse ntse ntawm 14.5 °, 15 °, 17.5 °, thiab 22.5 ° kuj tseem siv.

4) Dab tsi yog qhov txawv ntawm ib lub taub hau thiab ob lub taub hau cab? Tus naj npawb ntawm cov hniav ntawm tus cab yog hu ua "tus naj npawb ntawm lub taub hau", uas yog sib npaug rau cov hniav ntawm cov iav. Lub taub hau ntau dua, qhov loj dua lub taub hau.

5) Yuav ua li cas paub qhov txawv R (sab xis)? L (sab laug) Iav ncej ntsug hauv av tiaj tus iav hniav qaij rau sab xis yog lub iav sab xis, qaij rau sab laug yog lub iav sab laug.

6) Qhov txawv ntawm M (modulus) thiab CP (pitch) yog dab tsi? CP (Circular pitch) yog lub voj voos ntawm cov hniav ntawm lub voj voog. Chav tsev yog tib yam li cov modulus hauv millimeters. CP faib los ntawm PI (π) yields M (modulus). Kev sib raug zoo ntawm M (modulus) thiab CP yog qhia raws li hauv qab no. M (modulus) =CP/π (PI) Both are units of tooth size. (The dividing circumference = nd=zpd=zp/ l/PI is called the modulus

7) Dab tsi yog "rov qab"? The gap between the tooth surfaces of a pair of gears when they are engaged. Backlash is a necessary parameter for the smooth operation of gear meshing. 8) What is the difference between bending strength and tooth surface strength? Generally, the strength of gears should be considered from two aspects: bending and tooth surface strength. Bending strength is the strength of the tooth that transmits power to resist the tooth breaking at the root due to the action of bending force. The tooth surface strength is the frictional strength of the tooth surface during repeated contact of the meshed tooth. 9) In the bending strength and tooth surface strength, what strength is used as the basis for selecting the gear? In general, both bending and tooth surface strength need to be discussed. Txawm li cas los xij, thaum xaiv cov iav uas siv tsawg dua, tes iav, thiab cov iav meshing qis qis, muaj cov xwm txheej uas tsuas yog xaiv lub zog khoov. Thaum kawg, nws yog nyob ntawm tus tsim qauv txiav txim siab.
