Mukugadzirwa kwedu kwemaindasitiri, mabhaudhi anowanzo putika, saka nei mabhoti achiputsika? Nhasi, inonyanya kuongororwa kubva pamativi mana.
Muchokwadi, mabhaudhi mazhinji akatsemuka nekuda kwekuregedzera, uye anotyoka nekuda kwekusunungura. Nemhaka yekuti mamiriro ekusunungura bhoti uye kuputsa anenge akafanana neaya ekuputsika kwekuneta, pakupedzisira, tinogona kuwana chikonzero kubva kune simba rekuneta. Muchokwadi, simba rekuneta rakakura zvekuti hatigone kuzvifungidzira, uye mabhaudhi haadi simba rekuneta zvachose panguva yekushandiswa.
Chekutanga, kuputsika kwebhaudhi hakukonzeri nekusimba kwebhaudhi:
Tora M20 × 80 giredhi 8.8 yakakwirira-simba bhaudhi semuenzaniso. Huremu hwayo hungori 0.2kg, ukuwo huremu hwayo hudiki huri 20t, iyo yakakwira se100,000 yakapetwa uremu hwayo. Kazhinji, isu tinongoshandisa kusungira 20kg zvikamu uye tinongoshandisa chikamu chimwe chete chegumi chehukuru hwayo. Kunyangwe pasi pekuita kwemamwe masimba mumidziyo, hazvibviri kutyora churu chehuremu hwezvikamu, saka kusimba kwekusimba kweiyo threaded fastener yakakwana, uye hazvibviri kuti bhaudhi riparadzwe nekuda kwe simba risina kukwana.
Chechipiri, kuputsika kwebhoti hakusi nekuda kwekuneta kwesimba rebhoti:
Iyo yekusunga inogona kusunungurwa kazana chete muyedzero yakachinjika yevibration yekusunungura, asi inoda kuzunguza miriyoni imwe kakawanda mukuyedza simba rekuneta. Mune mamwe mazwi, tambo yakasungwa inosunungura kana ikashandisa chikamu chegumi chesimba rekuneta kwayo, uye isu tinongoshandisa chikamu chimwe chegumi chegumi chehukuru hwayo, saka kusunungurwa kwetambo yakasungirirwa haisi nekuda kwekuneta kwesimba rebhoti.
Chechitatu, chikonzero chaicho chekukuvadzwa kwema threaded fasteners kusununguka:
Mushure mekunge chisungo chasunungurwa, hombe kinetic simba mv2 inogadzirwa, iyo inoshanda zvakananga pane yekumisikidza uye zvishandiso, zvichiita kuti chisungo chikuvadzwe. Mushure mekunge fastener yakuvadzwa, iyo midziyo haigone kushanda mune yakajairika mamiriro, izvo zvinowedzera kutungamirira kune kukuvara kwemidziyo.
Iyo screw thread yefastener inoiswa pasi peaxial force inoparadzwa uye bhaudhi rinobviswa.
Kune zvisungo zvinoiswa pasi pesimba reradial, bhaudhi rinogerwa uye gomba rebhaudhi rine ovha.
Chechina, sarudza nzira yekukiya shinda ine yakanakisa kukiya mhedzisiro ndiyo yakakosha kugadzirisa dambudziko:
Tora hydraulic sando semuenzaniso. Huremu hweGT80 hydraulic hammer ndeye 1.663 matani, uye mabhaudhi ayo eparutivi maseti manomwe eM42 mabhaudhi ekirasi 10.9. Kusimba kwebhaudhi rega rega i110 tons, uye simba rekudzivirira rinoverengerwa sehafu yesimba resimba, uye simba repamberi rinokwira sematani mazana matatu kana mana. Zvisinei, bhaudhi richatyoka, uye zvino ragadzirira kuchinjwa kuva M48 bhaudhi. Chikonzero chakakosha ndechekuti kukiya bhaudhi hakugone kuzvigadzirisa.
Kana bhaudhi richitsemuka, vanhu vanogona kugumisa nyore nyore kuti simba rayo harina kukwana, saka vazhinji vavo vanotora nzira yekuwedzera giredhi resimba rebhoti dhayamita. Iyi nzira inogona kuwedzera pre-tightening simba remabhaudhi, uye simba rayo rekukwesha rakawedzerwawo. Ehe, iyo anti-kusunungura mhedzisiro inogona zvakare kuvandudzwa. Nekudaro, nzira iyi inzira isiri yehunyanzvi, ine mari yakawandisa uye purofiti shoma.
Muchidimbu, bhaudhi nderekuti: “Kana ukasarisunungura, rinotyoka.”
