Fastener torque le mathata a tloaelehileng

Karohano ea boikarabello bakeng sa torque ea fastener

1. PATAC e ikarabella bakeng sa ho lokolla torque e matla le torque ea pele e tsitsitseng.PATAC e lokolla maemo a matla a torque ho latela litlhoko tsa moralo, ho kopantsoe le liphetho tsa liteko le liphetho tsa liteko tsa 'mila.

2. ME e na le boikarabelo ba ho lokolla torque e tsitsitsengHo ea ka torque e matla e lokollotsoeng ke PATAC, torque ea sesebelisoa sa fastening e fetotsoe ka Nominal value ea tekanyo e matla ea torque moleng oa tlhahiso.Ebe torque e tsitsitseng e lekanyetsoa ho latela mokhoa o tloaelehileng oa tlhahiso.Ho sebelisa mokhoa oa lipalo (lihlopha tse 30 tsa data), ho fumanoa Nominal le mamello ea static torque standard, 'me tekanyo ea torque e tsitsitseng e fumanoa.

Torque e matla le sebopeho sa ho ngola sa torque e tsitsitseng

1. Torque e matla

Lintlha tse amang torque e matla

Ha u beha torque e matla, u se ke ua nahana feela ka li-fasteners, empa hape u nahane ka li-fasteners le lisebelisoa tse matlafatsang.The dynamic torque e kholo haholo, e leng bonolo ho etsa hore li-fasteners li fane, esita le ho robeha, meno a thelle, 'me li pshatlehe ka li-fasteners.Bothata ba lintho tse bonahalang, ho rarahana ha holim'a metsi, coefficient ea ho ferekana ha holim'a metsi le sebopeho sa fastener se tla ama torque e matla e hlokahalang. .Ka nako e ts'oanang, ho boetse hoa hlokahala ho nahana ka matla a fastener ho etsa bonnete ba hore e ke ke ea sithabetsoa, ​​'me joale u fumane torque e kholo eo sekontiri se ka se khonang. fastener.Torque e fokolang e matla e lokela ho etsa bonnete ba hore ha e lokolohe ts'ebetsong ea ts'ebeliso ea bareki, 'me torque e kholo e lokela ho etsa bonnete ba hore fastener le fastener ha li hlolehe (tse kang ho inehela, ho senya, ho thella, ho senya, ho senya, joalo-joalo). Bakeng sa ho fana ka papali e felletseng ts'ebetsong ea li-fasteners, axial preload ea li-fasteners ka kakaretso e lokela ho ba 50 ho 75% ea mojaro o tiisitsoeng oa li-fasteners.
