1. Lub zog ntawm lub zog yog tsuas yog los tswj lub precision ntawm kev sib kis ntawm cov zog ntawm kev khiav ntais. Piv txwv: tus smoothness ntawm cov kis tau tus mob, lub volatility ntawm instantaneous degree, thiab yog hais tias muaj alternating cov lag luam hauv nraud, seb lub backlash ntawm cov hniav yog qhov tsawg, yog muaj muaj qhov nyhav feem me me nce lub cav, yog li kom txo tau qhov kev puas tsuaj los ntawm kev cuam tshuam rau cov iav.
2, yog tias qhov kev tsim cov qauv hais saum toj no yuav tsum muaj kev sib raug zoo, qhov yuav tsum tau muab tso rau ntawm qhov tsawg dua, thiab lwm yam.
3. Txawm li cas los xij, yog hais tias lub iav precision raug teeb tsa siab dhau lawm, nws yuav ua rau kom tus nqi khiav lag luam thiab yuav tsum muaj kev sib npaug.
4. Cov tsis zoo saum toj no yeej muaj zog uas feem ntau siv. Qhov tseeb yog txhais tias: 7FL, lossis 7-6-6GM.
7FL: Kev ua siab ntev ntawm peb pab pawg ntawm cov iav yog tib yam li ntawm 7th iav, qhov sib txawv ntawm qhov hnyav ntawm cov hniav ua rau F-hoob kawm, thiab qhov qis ntawm qhov hnyav ntawm tus hniav yog L-chav kawm.
7-6-6GM: Qhov tseeb ntawm thawj txheej ntawm tolerances ntawm lub zog yog 7 thiab qhov tseeb ntawm ob txheej ntawm tolerances ntawm lub zog yog 6. Cov kam ntawm peb txheej ntawm lub zog yog 6 thiab lub siab sib txawv ntawm cov hniav tuab yog G., Qhov sib txawv ntawm cov hniav thickness yog M theem
5, yog tsis muaj mis rau qhov tseeb ntawm cov iav, vim tias tsis muaj kev xav tau, nws yog xyuas cov phau ntawv.
6, kev txiav txim siab ntawm qhov tseeb yog qhov tshwm sim ntawm kev soj ntsuam ntawm engineers, kev xav tau kev sib kis ntawm qhov kev txiav txim siab, los yog kev kub siab, hloov kev hloov ... ... qhov tseeb qib yuav raug teev me ntsis siab dua
7, qhov tseeb theem ntawm 5,6,7,8,9,10, qhov me me tus nqi ntau dua lub precision
8. Lub plhu (qhov sib ntxiv ntawm qhov hniav) sib txawv me ntsis kuj yog qib uas muab los ntawm tus kws kho mob rau cov zwj ceeb tshwj xeeb. Qhov tseeb kis tau tus mob kis tau yooj yim, qhov kev siv dav dav rau qis qis me ntsis, tus tsav raug kaw me ntsis ntxiv, thiab qhib tsav qis qis dua.
9, (lub pluaj tuab) kev sib hloov hauv chav kawm C, D, E, F, G, H, J, K, L, M, N, P, R, S qib, C-qib siab tshaj qhov tseeb, S-chav kawm sib txawv yam tsawg.
10. Txawm tsis muaj qhov tseeb lossis theem sib txawv, qhov siab dua qhov chaw, qhov nqi siab dua tus nqi. Tom qab ib qho kev ntsuam xyuas dav dav, ib qho kev txheeb meej thiab qib theem yuav tsum raug muab.
11. Rau kev kuaj pom yam khoom muaj zog, muaj peb pawg kws tshuaj ntsuam xyuas, uas yog raws li nram no:
12. Thawj pawg ntawm cov khoom tshuaj xyuas yog qhov tseem ceeb los xyuas kom meej tias qhov tseeb ntawm kev sib kis. Cov khoom muaj xws li: tangential comprehensive tolerance Fi ', txhua lub limtiam kev ua siab ntev, Fp, k circumferential cumulative kam rau siab Fpk, radial ntse siab kam ", nplhaib iav Radial Runout Tolerance Fr, Common Qhov ntev Variation Tolerance Fw
13. Pab pawg thib ob ntawm kev soj ntsuam mas yog los xyuas kom meej qhov smoothness, suab nrov thiab kev vibration ntawm kev sib kis. Cov khoom muaj xws li: tangential one-tooth synthetic tolerance fi ', base section txwv sib txawv fbp, txhua seem hauv ib lub lim tiam sib txawv me ntsis fpt, radial ib qho tshuaj synthesis fais fab tuag fi "
14. Cov pab pawg thib peb ntawm cov khoom tshuaj xyuas yog qhov tseem ceeb los ua kom tsis muaj qhov sib thooj ntawm kev faib khoom. Cov khoom muaj xws li: koob tshuaj tiv thaiv hniav muag Fβ, tiv tauj kab kab mob kam Fb, axial suab txwv kev sib txawv Fpx
15. Cov qhabnias zoo ntawm cov iav dawb paug: 5, 6, 7, 8, 9, 10
16, qhov nyob nruab nrab ntawm kev sib tos ntawm iav, thiab nws cov av sab hauv: IT5, IT6, IT7, IT8 qib
17. Dimensional Tolerance ntawm Iav Shafts thiab Lub Koom Txoos Qhov Ncaj Ncees: IT5, IT6, IT7
18. Sab saum toj ntawm lub voj voog uas siab ntev: IT7, IT8, IT9
19. Radial runout ntawm kev siv dav hlau thiab qhov kawg ntawm qhov chaw dav hlau siv: Raws li qhov loj ntawm txoj kab uas hla kab, kos lub rooj raws li qhov loj ntawm 5, 6, 7, 8, 9, 10
20, yuav tsum tau piav qhia: Kuv muab thawj pawg, pawg thib ob, pab pawg thib peb ntawm kev soj ntsuam cov kev tshawb fawb ntau dua, tab sis qhov tseeb, hauv cov duab kos, peb tsis muaj ntau qhov kev soj ntsuam ntau ntau cov kev xeem tsis yog ua rau cov teeb meem rau kev soj ntsuam, tab sis kuj nce nqi raug tsim. Yog li ntawd, tsuas yog qee tus xwb thiaj tuaj yeem tshawb xyuas cov duab kos. Koj tuaj yeem xa mus rau cov kev kos duab ntawm iav, thiab koj tuaj yeem saib ntawm Phau Ntawv Mechanical Design Manual. Piv txwv li, ntawm no yog ib daim ntawv teev cov khoom uas niaj zaus tshawb xyuas thiab teev rau hauv daim duab:
21, tshuaj ntsuam cov tshuaj pinion:
21. Raws li cov lus koj muab rau saum toj no, cov theem qis ntawm pinion iav tau teem rau 7FL, thiab qib tom ntej yog qhov tseeb ntawm qhov tseeb phau ntawv:
22, lub lim piam txaav nrug FP: 0.063
23, lim tiam ib lub lim tiam sib txawv: f.0: 0.018
24. Cov kab mob vov uas khij rau hauv daim duab: Lub hauv qhov taw qhia raws li IT7 theem: Kos cov "Standard tolerance table" raws li lub qhov loj hauv phau ntawv.
25, sab saum toj lub voj voog radial khiav: kos lub "txuj siab rau qhov rooj" raws li qhov loj ntawm lub dav diameter
26, loj cov khoom kuaj mob loj:
27, Ua siab ntev tso siab rau Fp: 0.090
28, lim tiam ib lub lim tiam sib txawv: 0.020
29. Lub voj voos ntawm lub voj voog rau ntawm daim duab: Lub qhov nyob sab hauv raws li IT7: xyuas qhov "Standard tolerance table" raws li lub qhov loj me hauv phau ntawv.
30. Radial runout ntawm lub voj voog saum toj: kos lub "txuj ci siab kam" raws li qhov luaj li cas sab nraud
