Dhaimondi denderedzwa rekuona mablades ane hunhu hwakajeka hwechimiro cheplate yakatetepa, uye anowanzoita deformation panguva yekuona, izvo zvinokanganisa kugadzikana kwesimba panguva yekugadziriswa. Kuongorora kugadzikana kwedhaimondi circular saw blades, zvinonyanya kutangira pakushushikana, mafambiro echisikigo uye mutoro wakakomba wemasaha akatenderedzwa panguva yekugadziriswa. Kune akawanda maitiro parameters anokanganisa zviri pamusoro apa zviratidzo, zvakadai sesaha blade kutenderera kumhanya, clamping flange dhayamita, blade ukobvu, blade dhayamita uye sawing kudzika, etc. vakasarudzwa kubva pamusika. Nekuchinja maitiro akakosha maparamita, iyo inogumira yekuongorora chinhu nzira uye yakanyanyisa musiyano wekuongorora nzira inoshandiswa kuwana mabatiro eiyo yakakosha maitiro paramita pane yekushushikana mamiriro, yakasikwa frequency uye yakakosha mutoro wedenderedzwa saw blade, uye kuongorora nekugadzirisa iyo key process parameters yekuvandudza kusimba kwesimba resaha blade. The theoretical hwaro hwepabonde.

1.1 Mhedzisiro ye clamping disc dhayamita pane saw blade stress.

Kana iyo yekutenderera kumhanya kweye denderedzwa saw blade inosarudzwa se 230 rad / s, dhayamita yeplamping plate.

iri 70 mm, 100 mm uye 140 mm zvakateerana. Mushure mekupedzisira chekuongorora chinhu, iyo unit node kushushikana kwesaha blade

inowanikwa pasi peakasiyana clamping disc diyamita zvipingamupinyi, sezvakaratidzwa mumufananidzo 5b. Sezvo dhayamita ye

clamping plate inowedzera, kushushikana kweiyo unit node yesaha blade inowedzera; zvisinei, apo kumanikidzirwa

mhando yeplamping plate inovhara maburi mana ekuderedza ruzha pashizha resaha [10-12], kukosha kwekushushikana.

inoderera nekuwedzera kwedhayamita yeclamping plate.

1.2 Effect of saw blade ukobvu pane saw blade stress

Kana iyo denderedzwa yakaona blade kutenderera kumhanya inosarudzwa pa230 rad/s uye dhisiki rinosunga rine dhayamita ye

100 mm inosarudzwa kuti iite chisungo chakakwana pane blade yesaha, ukobvu hwesaha blade hunoshandurwa.

uye kushushikana kwenzvimbo yeyuniti node ine ukobvu hwe2.4 mm, 3.2 mm uye 4.4 mm yesaha

yakaongororwa nefinite element. Shanduko yemaitiro meta-node stress inoratidzwa muMufananidzo 5c. Nekuwedzera kwe

kuwanda kwesaha blade, kushushikana kwekubatana kweiyo saw blade unit kwakaderedzwa zvakanyanya.

1.3 Mhosva yedhayamita yeblade yesaha pakudzvanya kweblade

Iyo saha blade inotenderera kumhanya inosarudzwa se230 rad/s, uye flange ndiro ine dhayamita ye100 mm

yakasarudzwa kuti iite chirambidzo chakakwana pasaha. Kana ukobvu hwesaha blade iri 3.2 mm,

iyo dhayamita yesaha blade inochinjirwa kune yekushushikana mamiriro eyuniti nodes ane saw blade madhayamita e

318 mm, 368 mm uye 418 mm zvichiteerana. Kune magumo ekuongorora chinhu, shanduko yemaitiro eunit node stress ndeye

inoratidzwa Mufananidzo 5d. Mune sawing mode yekugara mutsara kumhanya, pamwe nekuwedzera kwehupamhi hwesaha

blade, kushushikana kwekubatana kweiyo saw blade unit kunowedzera zvakanyanya.

Kuongorora kwakashata kwakanyanya kwekukanganisa kweiyo iri pamusoro pemaitiro paramita pakushushikana kwesaha ndeye

inoratidzwa muTebhenekeri 3. Inogona kuonekwa kuti chiyero chekuchinja kwemaitiro ekugadzirisa uye kushungurudzika kwakanyanya

musiyano unoenderana neTafura 3 inoratidza kuti kumhanya kweshizha resaha kune yakanyanya kukanganisa pane

kushushikana kwekubatana kweiyo saw blade unit, dhayamita yesaha uye ukobvu hwesaha blade,

ichiteverwa nekukanganisa kushoma padhayamita yeplamping plate. Hukama huri pakati pesaha

kugadzirisa kugadzikana uye kushushikana ndeye: kudiki kukosha kwekunetseka kwesaha blade, zviri nani kugadzirisa

kugadzikana kwesaha. Kubva pakuona kwekudzikisa kushushikana kweyuniti node uye kugadzirisa iyo

kugadzirisa kugadzikana kweshizha resaha, kuderedza kutenderera kwekutenderera kweshizha resaha, kuwedzera kukora

yeshizha resaha, kana kudzikisa dhayamita yeshizha resaha mumamiriro ekugara mutsara wekucheka can

kunatsiridza kusimba kwakasimba kwesaha blade; iyo dhayamita yeclamping ndiro inosungwa nekuti kana

vhara gomba rekudzikisa ruzha, uye kugadzikana kwekugadzirisa kwesaha kunze kwegomba rekudzikisa ruzha.

iri pamwe neplamping plate. Iyo dhayamita inowedzera uye inokwira, uye zvinopesana ndezvechokwadi mukuderedza ruzha

gomba.
