Parizvino, mhete yekucheka inoshandiswa zvakanyanya mundima dzakawanda.Asi vanhu vazhinji havazivi nzira yekusarudza saizi yakakodzera yemhete yekucheka.Senyanzvikuurayamugadziri, isu,XZWD Slewing Bearing Co., Ltd, nhasi tichazivisa zvakadzama maitiro ekuverengera kunzekuurayasaizi.
1.Iyo inotakura simba curve ye slewing bear
Imwe neimwe mhando yekuurayayemasampuli echigadzirwa ane inoenderana inotakura-inotakura simba curve, uye girafu inogona kubatsira mushandisi kusarudza iyokuurayapreliminary.
Kune marudzi maviri emacurve, imwe ndiyo static curve (① line), iyo yakanyanya kuremerwa iyokuurayainogona kutsungirira kana ikaramba yakamira.Imwe yacho ibolt load limit curve (8.8, 10.9, 12.9), inosarudzwa kana urefu hwebhaudhi hwakareba kashanu sedhayamita yebhaudhi, uye preload i70% yemuganho wegoho rebhaudhi.
- 2.Kuverengera nzira yekusarudza bheya
1) Nzira yekusarudza
Ita shuwa iyo yakanyanya kuremerwa iyokuurayainogona kutsigira kana ikaramba yakamira (axial load Fa, radial load Fr, kupidigura nguva M).Isa iyo yakanyanya kuremerwa seyakamira chiyero kukosha.Static mwero kukosha kunofanirwa kutarisisa iyo yaivepo yakanyanya kuremerwa pamusimboti, iyo inofanirwa kupedzisa iyo yekuwedzera mutoro uye yekuedza mutoro.
Ita shuwa iyo static chengetedzo coefficient fs zvinoenderana nerudzi rweinjini huru (application mamiriro), ane nhamba kukosha ona tafura 1.
Kutanga sarudza rudzi rwekuuraya, ita shuwa nzira yekuverenga ye static referensi mutoro Fa uye M.
Verenga Fa uye M
Static load limit curve inoenderana nerudzi rwakasarudzwa rwekuurayapakati pemienzaniso, womaka (Faˊ，M ˊ)
Tarisa uone kana iyo coordination point (Faˊ，M ˊ) iri pasi peiyo static load limit curve
Kutarisa kuverenga kweiyo bhaudhi yekutakura simba (ona ichi chikamu 5.2.4)
2) mhando sarudzo mune static
Kuverengera nzira ye static referensi mutoro Fa 'uye M'
Nzira I(a=60°)
Iko kuverengera kusarudzwa kwe-single-row four point contact ballkuurayaprocess by load support angle 45° uye 60° zvichiteerana .
Nzira I (a = 60 °)
Fa′=(Fa+5.046×Fr)×fs
M ′=M×fs
Nzira II(a=45°)
Fa′=(1.225×Fa+2.676×Fr)×fs
M ′=1.225×M×fs
Mune formula: Fa '-kuurayayakaenzana pakati axial simba (104 N )
M'-kuurayanguva yakaenzana yekupidigura (N. m)
fs-chengetedzo chinhu mumamiriro ekushanda akasimba ekutsigira kuuraya (ona tafura 1)
Wobva watsvaga mapoinzi maviri ari pamusoro pacurve, imwe yacho iri pazasi pecurve.
Single-row crossed roller type
Fa′=(Fa+2.05×Fr)×fs
M′=M×fs
Mhando yebhora-mitsetse miviri
Iko kuverengera kusarudzwa kwebhora-mutsara wakasiyana dhayamita bhorakuuraya, kana Fr <= 10% Fa, shanduko yekumanikidza angle mukati memujaho inofanira kuverengerwa, ndapota taura nesu nezve maverengero ayo.
Fa'= Fa×fs
M ′=M×fs
Mitsara mitatu yemhando ye roller
Pakusarudza katatu-row rollerkuuraya, ingoverenga kupindirana kweaxial raceway mutoro uye nekupidigura nguva.
Fa'= Fa×fs
M ′=M×fs
2) Dynamic sarudzo
Ndokumbira ubate dhipatimendi redu rehunyanzvi kuti ushandise kuenderera mberi kwekushanda, kumhanyisa kutenderera uye zvimwe zvikumbiro zvehupenyu hwesevhisi yerutsigiro rwekutenderera.
3) Kutarisa kuverenga kwebhoti yekutakura simba
Iyo yakanyanya kuremerwa (hapana static kuchengetedza factor fs) inoshandiswa kurodha kutenderera kutsigirwa.Tarisa kana mutoro uri pazasi pemuganho wekutakura curve yegiredhi inodiwa mabhaudhi;
Kana iyo bhaudhi inotakura simba isina kukwana, tinogona kusarudzakuurayazvakare kana kubata dhipatimendi redu rehunyanzvi.
Iyo fekitori inogona kupa ruzivo zvinoenderana neyakagadzirwa sampu, uchishandisa iyo static bearing capacity curve, zvinoenderana neinotenderera inotakura mhando yekusarudza nzira yekuverenga yekutanga kusarudzwa.kuuraya, uye tekinoroji nekambani yangu yekusimbisa.Inogonawo kupa ruzivo rwekutenderera kukambani yedu, kana uchiita sarudzo yekugadzira nekambani yangu, ndapota bvunza iyo 《inotenderera inotakura sarudzo yetekinoroji tafura tafura 》(kusanganisira annex A uye annex B patafura yeparameter), uye zadza. mukati, kuitira kuti tigone kuzviisa kwauri nekukurumidza sezvinobvira kwakaringana rotary kutakura sarudzo yehurongwa hwehupfumi uye hunoshanda.
