    Torque required to tighten the cap for leak proof

    For thread engagement force : Frictional force, Ff = m g (sin α + μ cos α) For comp. of seal : E = Stress / Strain Stress = E*Strain Force/Area = E*Strain Force = E*Strain*Area Resultant force = Frictional force + Comp. force And the Compressive torque, Tc = K x Force x d (where k=Coeff...

    Torque required to tighten the cap for leak proof

    Yeah. I consider frictional force of thread engagement too while doing torque and got the result of ~20Nm. Hope in lead screw torque Calc. approach also friction parameter will be considered right?

    Torque required to tighten the cap for leak proof

    Thanks for your suggestion. As per the water pressure, I suppose to compress the seal by 40% based on this if I directly estimate the torque I'll get ~20Nm. If I use torque formula of lead screw concept, I'll get ~65Nm. So got confused. Guide me which way I need to go

    Torque required to tighten the cap for leak proof

    What approach should I consider? Shall I go with lead screw torque calc.? or any other

    Torque required to tighten the cap for leak proof

    Hello Anyone, Could you help me in finding the torque req. for a cap to leak proof? My cap (polyproplene) which dia. was 32mm and its detail specs are, thread major dia.- 28.5mm, min. dia. - 26mm, pitch - 3mm, thread angle-45deg which has a EPDM rubber seal placed inside (outer dia 26.5mm &...
