Coefficients of Friction
The coefficient ea khohlano ea PTFE thepa e itšetlehile ka tse ngata tse feto-fetohang, ho akarelletsa le khatello, thellehang lebelo le mocheso.Maikutlo a arotsoe ka phello ea mefuta e meng, leha ho lumeloa hore khatello e phahameng le lebelo le tlase li rata khohlano e tlase.
Coefficient e ka tlase ho ea lisebelisoa tse ling tse tiileng tsa boenjiniere.E tlalehiloe ka mokhoa o fapaneng ho tloha ho 0.02 ho isa ho 0.2, empa sena se ipapisitse le boitokiso ba bokaholimo le mokhoa oa tlhahlobo.Chate ea mojaro / khohlano e bonts'a phello ea mojaro.
Ka kakaretso, coefficient ea khohlano pakeng tsa mating surface le PTFE slide bearing pad e tla ba bonyane ha khatello ea kelello ho PTFE e le holimo (ho lumellana le meeli e amohelehang ea creep), ho beleha ho entsoe ho tloha PTFE e sa tlatsoang, le qetello ea bokaholimo ba ho tsoala e bentšitsoe haholo.
Ho phaella moo, e 'ngoe ea litšobotsi tsa bohlokoa ka ho fetisisa tsa likhohlano tsa PTFE ke ho ba sieo ha 'stick-slip', hobane ho fapana le li-bearings tse ling tsohle tse tloaelehileng, khohlano e tsitsitseng ea PTFE e lekana kapa e phahame ka mokhoa o fokolang ho feta khohlano e matla.
