Fastener torque uye matambudziko akajairika

Kupatsanurwa kwemabasa eiyo fastener torque

1. PATAC ine basa rekuburitsa dynamic torque uye yekutanga static torque.PATAC inoburitsa dynamic torque chiyero zvinoenderana nedhizaini zvinodiwa, zvakasanganiswa nemhedzisiro yekuyedza uye mhedzisiro yemugwagwa.

2. ME ine basa rekuburitsa static torqueMaererano neiyo dynamic torque yakaburitswa nePATAC, torque yechishandiso chekusimbisa inogadziriswa muNominal kukosha kweiyo dynamic torque standard pamutsetse wekugadzira.Ipapo iyo static torque inoyerwa zvinoenderana neyakajairika kugadzirwa modhi.Uchishandisa nzira yehuwandu (30 seti yedata), iyo Nominal uye kushivirira kweiyo static torque standard inowanikwa, uye iyo static torque standard inowanikwa.

Dynamic torque uye static torque yekunyora fomati

1. Dynamic torque

D zita+/-kushivirira NM;Dynamic torque yakanyorwa nenzira yezita +/kushivirira senge D30 +/- 5nm;Hapana nzvimbo iri pakati peD ne30+/-5NM;Apo D inomiririra Dynamic;NM ndiyo chikamu che torque: Newton.Meters;kushivirira kunofanirwa kuve kwakafanana kushivirira uye hakufanirwe kuiswa kune chimiro cheasymmetric kushivirira kumusoro uye pasi.Semuenzaniso, D30 + 3/-5NM haina kururama.Muchigadzirwa, iyo inoshanduka torque kukosha kwechigadziro chekusimbisa inofanira kunge iri mazita, uye haifaniri kubviswa kubva kune zita rekukosha nemaune;

2. Static torque

SA-BNM;Iyo static nguva inofanirwa kunyorwa semhando yemafomu akadai se: S25-35NM;Hapana nzvimbo pakati peS uye 25-30NM;Apo S inomirira Static;A inomiririra muganho wakaderera we static torque, B inomiririra muganho wepamusoro we static torque;NM ndiyo chikamu che torque: Newton.Meters;

3. Dynamic torque yezvipikiri zvakazvigarira Mipikiri inozvigarira inowanzogara pasi peiyo FDSNS standard (Fully DrivenSeated Not Stripped) .Somuenzaniso: D1.5+/-0.5NM S1NM MIN FDSNSWipapo D inomirira Dynamic(dynamic);Inoteverwa nenzvimbo; 1.5 +/- 0.5NM inoratidza huwandu hweiyo dynamic torque, 1.5NM inongova yereferensi yeiyo chaiyo set torque mukugadzira, uye haina kuratidzwa seNominal kukosha.Iyo chaiyo dynamic torque inoshandiswa inogadziriswa nekugadzirwa maererano nemamiriro chaiwo epfuti ine simba torque, asi inofanira kuve nechokwadi kuti FDSNS standard (Fully Driven SeatedNot Stripped, kureva, zino harina kutsvedza). Pakupedzisira, ona FDSNS (Yakatyairwa Zvizere NotStripped).

Zvinhu zvinokanganisa dynamic torque

Paunenge uchiisa torque ine simba, funga kwete chete zvigadziriso, asiwo zvigadziriso uye zvigadziriso zvekushandisa.Iyo dhizaini torque yakanyanya kudiki, iyo iri nyore kukonzera kusunungura uye kuneta kuputsika, uye haigone kukudziridza kugona kwezvisungo;Iyo dynamic torque yakakura kwazvo, iyo iri nyore kuita kuti mafasteners abudise, kunyange kutsemuka, mazino anotsvedza, uye kupwanywa nemafasteners.Kuoma kwezvinhu, kushata kwepamusoro, friction coefficient uye chimiro chefastener ichakanganisa iyo dynamic torque inodiwa. .Panguva imwecheteyo, zvakakoshawo kufunga nezvesimba rekusungirira kuti ive nechokwadi chekuti harizopwanyika, uye wobva wawana iyo yakanyanya torque iyo iyo fastener inogona kumira. fastener.Iyo shoma ine simba torque inofanirwa kuve nechokwadi kuti haina kusununguka mukushandiswa kwevatengi, uye iyo yakanyanya torque inofanirwa kuve nechokwadi chekuti chisungo uye chekusunga hachikundike (sekuregedza, kutyora, kutsvedza, kupwanya, deformation, nezvimwewo). Kuti upe kutamba kwakazara kukuita kwezvitsigiro, iyo axial preload yezvisungo inofanira kunge iri 50 kusvika 75% yemutoro wakavimbiswa wezvisungo.
