Bolt sechishandiso chinowanzoshandiswa mukugadzirisa, kushandiswa kwakanyanyisa, asi kushandiswa kwenguva refu kuchaunzawo matambudziko akawanda, akadai sekubatanidza slack, kusakwana kwesimba rekugadzirisa, bolt rust nezvimwe zvakadaro. Hunhu uye kushanda zvakanaka kwekugadzira kuchakanganiswa nekuda kwekubatana kwakasununguka kwemabhoti panguva yekugadzira zvikamu. Saka sei kusunungura bhaudhi?
Kune nzira nhatu dzinowanzoshandiswa dzinopesana nekusunungura: friction anti-loosening, mechanical anti-loosening uye zvachose anti-loosening.
- Bolt kaviri
Nheyo yekurwisa-kusunungura nati pamusoro: pane maviri anokweshana epamusoro apo nzungu mbiri dzinopesana nekusunungura. Yekutanga friction surface iri pakati pe nut ne fastener, uye yechipiri friction surface iri pakati pe nut ne nut. Panguva yekumisikidza, preload yekutanga friction surface i80% yechipiri friction surface. Pasi pesimba uye mitoro yekuzununguka, kukwenya kwekutanga kukweshana kunoderera uye kunyangarika, asi panguva imwecheteyo, nati yekutanga inomanikidzwa, zvichikonzera kuwedzera kuwedzera kwekukwenya kweyechipiri friction surface. Kukwenya kwekutanga nekwechipiri kunofanira kukundwa kana nati yasunungurwa, sezvo simba rechipiri rekukwenya rinowedzera sezvo simba rekutanga rinodzikira. Nenzira iyi, iyo inopesana-kusunungura maitiro ichava nani.
Pazasi shinda inopesana nekusunungura musimboti: Zvisungo zvepasi zvinosungirira zvinoshandisawo nzungu mbiri kudzivirira kusunungura, asi nzungu mbiri idzi dzinotenderera dzakatarisana. Pasi pesimba uye mitoro yekuzununguka, kukweshera kwekutanga kukwesha kwepasi kunoderera uye kunyangarika.
- 30 ° wedge shinda anti loose tekinoroji
Pane 30° wedge bevel pazasi pezino re30° wedge female thread. Kana mabhaudhi nuts abatanidzwa pamwe chete, matipi emazino ebhaudhi anotsikirirwa zvine mutsindo paberere reshinda yemunhukadzi, zvichikonzera kukiya simba guru.
Nekuda kwekuchinja kweAngle ye conformal, simba rakajairwa rinoshandiswa pakubata pakati petambo iri paAngle ye60 ° kune bhaudhi shaft, pane 30 ° sekunge netambo dzakajairwa. Zviripachena kuti dzvinyiriro yakajairwa ye30° wedge shinda yakakura kwazvo kudarika clamping pressure, saka inokonzeresa anti-loosening friction inofanira kuwedzerwa zvakanyanya.
- Kubva kukiya nzungu
Yakakamurwa kuita: inoshandiswa kumichina yekuvaka mugwagwa, michini yemigodhi, michini yemagetsi vibration yehurefu-simba yekuzvivharira nzungu, inoshandiswa mumhepo, ndege, matangi, michina yemigodhi, senge nylon yekuzvivharira nzungu, inoshandiswa kushanda kudzvanywa haisi yakakura kupfuura 2 ATM yepeturu, parafini, mvura kana mhepo semhepo inovhara 1 - 00 kuvharika kwemhepo. nati pachigadzirwa, uye chitubu chinosungirira kukiya nati.
- Thread locking glue
Thread locking glue is (methyl) acrylic ester, initiator, promoter, stabilizer (polymer inhibitor), dhayi uye filler pamwe chete mune chimwe chikamu chenamira.
Nekuburikidza negomba mamiriro: pfuudza bhaudhi kuburikidza nescrew gomba, isa shinda yekukiya glue kune shinda ye meshing chikamu, unganidza nati uye uisimbise kune yakatsanangurwa torque.
Kune iyo mamiriro ekuti kudzika kwegomba kwakakura kupfuura kureba kwebhaudhi, zvinodikanwa kuisa glue yekuvhara kune tambo yebhaudhi, kuungana uye kuomesa kune yakatsanangurwa torque.
Kune mamiriro egomba remapofu: donhedza glue yekuvhara kusvika pasi pegomba rebofu, wozoshandisa glue yekuvhara kune thread yebhoti, unganidza uye simbisa kune torque yakataurwa; Kana gomba remapofu richizarurwa pasi, chete glue yekuvhara inoshandiswa kune thread yebhoti, uye hapana glue rinodiwa mugomba rebofu.
Kune maviri-musoro bhoti yekushanda mamiriro: iyo yekuvhara glue inofanira kudonhedzwa mugomba rekutsvaira, uye ipapo glue yekuvhara inoputirwa pabhoti, uye stud inounganidzwa uye yakasimbiswa kune yakatsanangurwa torque; Mushure mokuunganidza zvimwe zvikamu, shandisai glue yekuvhara kune meshing chikamu chestud uye nut, unganidza nut uye uisimbise kune torque yakatarwa; Kana gomba rebofu rakavhurika pasi, hapana kudonha kweglue mugomba.
Kune pre-assembled threaded fasteners (sezvinogadziriswa screws) : mushure mekuunganidza uye kuomesa kune yakatsanangurwa torque, donhedza glue yekuvhara munzvimbo yemeshing yeshinda kuti ubvumire glue kupinda roga.
- Wedge-mu kukiya anti-yakasununguka kaviri paki washer
Radhial saw zino pamusoro pekunze kwewedged lock washer yakavharwa neworkpiece pamusoro painobatika. Kana iyo anti-kusunungura sisitimu inosangana neane simba mutoro, kutama kunogona kuitika chete mukati meiyo gasket.
Kuwedzera kureba kweweji yekiyi washer munzira yekuwedzera ukobvu kwakakura kupfuura kusimuka kwelongitudinal yebhaudhi yekuwedzera shinda.
- Split pini uye slotted nati
Mushure mekunge nzungu yasimbiswa, isa pini yecotter muberere renzungu neburi remuswe rebhaudhi, wovhura muswe wepini yecotter kudzivirira kutenderera kwakati kwenut nebhaudhi.
- Series simbi waya yakasununguka
Iyo anti-kusunungura yenhevedzano waya yesimbi ndeyekuisa waya yesimbi mugomba remusoro webhaudhi, uye kubatanidza mabhaudhi munhevedzano kuti zvibatane. Iyo inzira yakavimbika kwazvo yekuzorora, asi ine hunyengeri disassemble.
- Misa gasket
Mushure mekunge nati yakasimbiswa, bhenda iyo imwe-lug kana kaviri-lug stop washer parutivi rwenati uye chinongedzo kuti uvhare nati. Kana mabhaudhi maviri achida kupindirana kaviri, mabhureki maviri anowacha anogona kushandiswa kugadzira nzungu mbiri dzichibhurana.
- Spring washer
Iyo inopesana-kusunungura musimboti wewachisi yechirimo ndeyekuti mushure meiyo chitubu washer yakanyungudutswa, chitubu chewachi chinoburitsa elasticity inoenderera, kuitira kuti nati uye bhaudhi tambo yekubatanidza pair irambe ichichengetedza simba rekukwenya, inoburitsa nguva yekupikisa, kudzivirira nati kusununguka.
- Kupisa kunyunguduka kusungirira tekinoroji
Kupisa kunyunguduka yekusimbisa tekinoroji, pasina kudiwa kwekutanga-kuvhura, mune yakavharwa mbiri inogona kubatwa zvakananga kuti iwane kubatana, muindasitiri yemotokari inoshandiswa zvakanyanya.
Iyi inopisa inonyunguduka yekusimbisa tekinoroji inotonhora yekugadzira nzira yekuzvirova-rova uye screw joint mushure mekumhanyisa-kutenderera kutenderera kwemota kunoitwa kune pepa zvinhu kuti abatanidzwe kuburikidza nekusimbisa shaft iri pakati pemidziyo uye deformation yepurasitiki inogadzirwa nekukwenya kupisa.
- preloaded
Simba repamusoro bhaudhi yekubatanidza kazhinji haidi mamwe ekudzivirira-kusunungura matanho, nekuti mabhaudhi ane simba akanyanya anowanzoda yakakura isati yaomesa simba, yakakura kudaro isati yaomesa simba pakati pe nati nechikoniso kuti ibudise kumanikidza kwakasimba, kudzvanywa uku kunodzivirira kutenderera kweiyo nut friction torque, saka nati haizoregere.
