Fastener matambudziko akajairika uye kuongororwa

Mune mamwe maapplication iwe unogona kuisa torque kumusoro webhaudhi kana nut uye kuchengetedza kubatana kwakasimba; Mune anotevera mamiriro ekushandisa, zvinokwanisika kuisa torque kune chimwe chete chezvikamu:

 

1, kukanganisa kurongeka

Mumakomba ekupindira anokodzera, torque inofanira kuiswa kune nati yekuisa.

2, bhaudhi musoro nenzungu zvine maumbirwo akasiyana nemadhayamita

Kana musoro webhaudhi nenati zviine zvimiro zvakasiyana (senge hexagon head bolt ine square nut) kana kuti madhayamita akasiyana zvakanyanya, zviri nani kuisa torque padivi diki renzvimbo inotakura.Semuenzaniso, kana musoro webhaudhi uri mudiki pane nati, torque inofanira kuiswa kumusoro webhaudhi.Inogona kungonzwisiswa sesimba diki uye hukuru hukuru.

3. Zvinhu zvakasiyana

Kana zvinhu zviviri zvakasiyana zvinoda kusungirirwa pamwe chete, zviri nani kuisa simba rekusimbisa pachinhu chacho nekamwe kadiki kekukweshera, ndiko kuti, torque inosunga padivi zvingangoburitsa kukwesha kushoma.

4, refu bhaudhi application

Kana torque ikaiswa kumusoro webhaudhi refu kwazvo, dambudziko rekuputika kwemhepo riri nyore kwazvo kuitika, saka kushandisa torque kune nati munyaya iyi kuchabatsira kudzivirira dambudziko iri.

Iko kune kushandiswa kwakadaro kwekuti nut ine nut ine flange, asi musoro webhoti hausi, kureva kuti, friction radius kune rumwe rutivi rwe nut yakakura kudarika iyo padivi remusoro webhoti.

Kana iyo torque yekusimbisa yakatemwa kana nati ichizosimbiswa, ipapo dambudziko rekuremerwa rinogona kuitika kana musoro webhaudhi wakasimbiswa uchishandisa iyo torque.Kazhinji, inoda kusvika hafu ye torque inodiwa kukunda kukwesha pasi penzvimbo inoomesa, saka radius diki yekukwesha inokonzeresa kuti torque yakawanda ipinde mujoini yakarukwa uye nekudaro kukonzera matambudziko.

Zvichipesana, tichifunga kuti torque yakatemerwa maererano nekusimbiswa kwemusoro webhaudhi, kana nati yakasimbiswa, kureva kuti, torque inoiswa kudivi neyakakura friction radius, izvo zvinokonzeresa kusakwana preload pakubatanidza tambo yekupinza, uye inogona kukonzera matambudziko akasununguka.

 

Sei kushandisa washers?

(1) Kana iyo base zvinhu zvakapfava zvakanyanya, iyo yepasi yeplate zvinhu ichakuvadzwa panguva yekugadzira screwing mubhaudhi kana screw.Nekushandisa washers, iyi extrusion pressure inogona kugoverwa pamusoro penzvimbo hombe, kudzivirira kukuvadzwa kune yaamai ndiro pamusoro.

(2) Kana iyo base yakapfava zvakanyanya, uye gomba rakatenderedza chisungo chekuisa rakakuvadzwa, ipapo dambudziko rekudhonza-kuburikidza nekutadza rinogona kuitika panguva yekuputira mukati meiyo yekumisikidza, nekuti kazhinji, simba rinoshandiswa mukusimbisa maitiro rinokwana kudhonza chisungo kuburikidza nemidziyo yemubereki ndiro, uye kuvepo kwewachi kunobatsira kuburitsa diki yekumanikidza.

(3) Kana bhaudhi kana screw mukati meplate yaamai isiri yakatsetseka, yakati sandara, musoro wechibatiso ungangonamira, kuburikidza nekushandisa washer, unogona kuve nechokwadi chekuti pamusoro pebhaudhi kana screw slide uye kuita kuti kuiswa kuve nyore.

(4) Mamwe mawashi ane dhizaini yakakosha, kuitira kuti ave nebasa rekudzivirira kusunungura nzungu.Isu tinowanzo kudaidza rudzi urwu rwewachi kukiya washer, kune akawanda marudzi ezvimiro mafomu, yakashama muromo, nyeredzi uye masaisai zvichingodaro.Iyi mhando yewachi yekukiya inoda kushandiswa pamwe chete ne nut.

Zvinogona kuonekwa kuti mukuwedzera kune yakanyatsogadzirirwa kukiya washer, iyo yakasara yewasher inonyanya kugovera mutoro pasi pemusoro webhaudhi uye nut face, ndiko kuti, washer inongoita basa rekugovera mutoro wekubatanidza chimiro.

Chikonzero nei ma threaded fasteners akasununguka mushure mekuiswa kunonyanya kukonzerwa nekuchinjika mutoro, nekuti ichaita kuti mubatanidzwa utsvedze, saka isu tinogara tichisimbisa kukosha kwe preload, zvakakwana preload inogona kudzivirira zvinobudirira dambudziko rehama slide yejoini, uyezve kudzivirira kuitika kwekusunungura.Nekudaro, pakugadzikwa kwema threaded fasteners, kunyatso kudzora preload inyaya yakakosha, kunyangwe kana iyo tambo yakatarwa uye maturusi ekuisa asina kuchinja, maopareta akasiyana anogona kukonzera dambudziko rekusakwana preload.

Uye zvakare, isu hatigone kufuratira kuti kana washer yaiswa, washer haina kuchengetwa yakagadziriswa, inogona kutenderedzwa pamwe neaxis yeiyo threaded fastener, uye izvi zvichanyatso kanganisa torque yekupinza, uye zvino kukanganisa preload simba.

Mumakore achangopfuura, kushandiswa kweFlange fasteners kwakawedzera zvishoma nezvishoma, nokuti iyo flange inewo kukwanisa kugovera zvinonzwisisika simba rekutakura, uye kubvisa dambudziko rekutenderera rataurwa pamusoro apa, saka zvigadziro zveflange zvishoma nezvishoma zvichatsiva kushandiswa kwegaskets.

3. Basa rekutanga

 

Paunosarudza abhaudhi uye nutkubatanidza, iwe unofanirwa kuisa torsion simba kuti uwane kukiya kuburikidza ne torque chishandiso kana chipanera chebhuku, uye torque inozopedzisira yashandurwa kuita preload inodiwa nechikamu chekubatanidza, rimwe simba reiyo preload rinogona kuve nechokwadi chekuti kubatana kwekupokana nekudedera kusunungura uye kuneta, mune mazhinji maapplication, iyo yakakwira iyo preload, zviri nani.

Unotsanangura sei preload?Paunoomesa bhaudhi kana nati, pane kukakavara pakati pemusoro webhaudhi nemusoro weti. Sezvakangoita kana uchitambanudza chitubu, chitubu chinogara chichiyedza kudzokera pachimiro chayo. Iyo bhaudhi yakatambanudzwa inoedzawo kudzoka pahurefu hwayo hwepakutanga kuti isunungure kunetsana, saka pane kudzvanya kana kumanikidza simba, iyo inodhonza bhaudhi nenati yakanangana.Uye wobva wabatanidza mubatanidzwa.

4.Sum up

Kuburikidza nesumo iri pamusoro, tinonzwisisa kana torque inofanira kuiswa kumusoro webhaudhi kana kuti nati kana ichiomesa uye mamiriro anoenderana, basa rewasher uye nekuvandudzwa kweiyo flange fastener, maitiro ekuvimbisa pre-yakasimba simba rinodiwa pakuiswa.
