Giredhi 10.9 Torque-Shear Bolts
MaParamita Ekutanga Epakati
**Zvimiro Nezvinhu:** Zvimiro zvinojairika zvinotangira paM16 kusvika kuM30, nehurefu hunowanzova pakati pe40mm kusvika 220mm. Zvinhu zvinoshandiswa zvinosanganisira simbi dzesimbi dzakadai se20MnTiB ne35VB. Zvimiro zveM16-M24 zvinowanzoshandisa 20MnTiB, nepo zvimiro zveM27-M30 zvichishandisa 35VB. Zvinhu izvi zvinopa hwaro hwekushanda nesimba repamusoro kwemabhaudhi.
**Mitemo:** Inofanira kutevedzera GB/T3632-2008 standard. Musoro webhoti ucharatidzwa ne grade yekushanda ye 10.9S, apo "S" inomiririra bhoti rakasimba rezvivakwa zvesimbi, zvichiita kuti zvikwanise kuzivikanwa uye kuteverwa kwemhando yepamusoro.
Kuumbwa kwePair yekubatanidza: Pear yega yega yekubatanidza inosanganisira bhoti rimwe chete, nati imwe yakasimba yemhando ye10H, uye washer imwe yakasimba yeHRC35-45. Zvinhu zvitatu izvi zvinofanirwa kugadzirwa mubatch imwe chete kudzivirira kusiyana kwebatch kukanganisa kugadzikana kwekubatana.
Zviratidzo Zvikuru Zvekushanda
Hunhu Hwakanaka hweMichina: Sebhaudhi rine simba guru, simba rayo rekudhonza riri pakati pe1040-1240 MPa, simba rayo rekugadzira harisi pasi pe940 MPa, kureba kwayo hakusi pasi pe10%, uye mwero wayo wekudonha unosvika 42%. Inogona kutsungirira zviri nyore mitoro inochinja-chinja uye yakawanda isati yaiswa, inoratidza kutsungirira kwakasimba kuneta, uye inogona kuderedza stress amplitude pasi pemitoro inochinja-chinja, ichiwedzera hupenyu hwebasa rezvivakwa zvesimbi.
Kuramba Kuora Kunochinjika: Kurapa kwakasiyana-siyana pamusoro kunowanikwa. Kune nzvimbo dzakajairika, kuisa dema uye kuisa phosphating inzira dzakasiyana, kugadzira firimu rinodzivirira rinoenzanisa kudzivirira ngura uye kugadzikana kwehuwandu hwekukweshana. Kune nzvimbo dzakakosha dzakadai semapuratifomu egungwa nenzvimbo dzine munyu wakawanda, Dacromet coating kana hot-dip galvanizing zvinogona kushandiswa. Dacromet coating, se coating ine ushamwari nezvakatipoteredza inobva ku zinc-aluminium, inoratidza kudzivirira ngura kwakanyanya.
Zvakanakira zveMaumbirwo uye Kuvaka
Magadzirirwo Akasarudzika Echivakwa: Musoro webhoti wakaita sehowa une muromo wakaita sesprite kumagumo. Musoro uyu wakaita sesprite chinhu chakakosha pakuvaka uye kuongorora mhando. Pasi pemusoro pane chifukidziro chinodzivirira kutsvedza kudzivirira bhoti kuti risatsvedze kana kutenderera panguva yekuisa, zvichideredza matambudziko ekuchengetedza anokonzerwa nekuiswa zvisina kunaka.
Kuisa Zviri Nyore Uye Zvinoshanda: Kuisa kunoshandisa chipanera che torque chakatsaurirwa. Chinepa chekunze chinoiswa pa nati, uye chinepa chemukati chinoiswa pamucheto wakaita se sprite. Kusimbisa kunowanikwa kuburikidza ne counter-force. Kana torque yasvika pamutengo wakajairika, mucheto wakaita se sprite unotyoka otomatiki, zvichiratidza kuti preload yasvika 95-105% yemutengo wedhizaini. Izvi zvinobvisa kudiwa kwekuyera torque nemaoko uye zvinodzivirira zvikanganiso zvinokonzerwa nekuchinja-chinja kwe friction coefficient munzira dzechinyakare dze torque, zvichiita kuti kunaka kwekuvaka kuve nyore uye kudzoreka.
Nzvimbo Huru dzeKushandisa
Bhaudhi iri chinhu chikuru chekubatanidza simbi uye rine mashandisirwo akasiyana-siyana. Mubasa rekuvaka, rakakodzera machubhu epakati ezvivakwa zvirefu, matrusses enhandare hombe, majoini ematanda emafekitori, nezvimwewo; muinjiniya yemabhiriji, rinogona kushandiswa pakubatanidza main beam, kubatanidza bridge deck uye majoini ekusimbisa shongwe yebhiriji; pamusoro pezvo, rinogona zvakare kushandiswa kune michina inorema senge tower cranes newind turbine towers, pamwe nekubatanidza simbi munzvimbo dzakakosha senge offshore platforms ne transmission towers, uye rinoenderana nemhando dzakasiyana dzekubatanidza dzakadai se friction type ne pressure type kuti zvisangane nezvinodiwa zvakasiyana zvekumanikidzwa.
