Torsion spring what are the main parameters

Torsional spring belongs to spiral spring. Torsion spring to be able to store and release angular momentum or according to the torsion body axis rotation arm to static data stationary one equipment. The top of the torsion spring is fixed to the other parts, while other parts around the spring management center turns, the spring bring them back to the original position, torque or turning force. 

 Then the main parameters of what it? Here and spring manufacturers together to learn about: inside diameter tolerance + / - 2%. De( Diameter) : equivalent diameter plus two times the wire specifications. Torsion spring, during the whole process in a work will narrow diameter, tolerance, ±2%±0. 1) mm。 L0( Of course the length) : watch out for: work in length will reduce, of course, during the whole process of tolerance + / - 2%. Ls( Support plate length) : this is a spring coil axis to the length of the spring supporting plate, the tolerance + / - 2%. An( Larger distortion Angle) : large distorted perspective of torsion spring, tolerance + / - 15 degrees. d( Spring wire specifications) : the main parameters of the diameter of the spring line. Dd( Large shaft diameter. ) Main parameters: the narrative in the industrial production using the spring shaft of large diameter and tolerance + / - 2%. Di( Inner diameter) Lose twice: the inner diameter of the spring is equal to the diameter of wire specifications.

 Torsion spring in the work process, the inner diameter can reduce to the axis neck diameter, A1 & amp; f1 M1:( Distortion Angle, load and torque) Perspective: the following is the formula to calculate the distortion A1 = M1 / R. Understanding of load, can use the formula to calculate M = F * Ls estimates torque. Fn( Larger load) : allow the effect on the torsional spring support board is strong, tolerance + / - 15%. Mn( Maximum torque speed) : allows larger torque ( Copernicus * mm) , tolerance + / - 15%. R( Spring stiffness) Main parameters: a clear spring work if frictional resistance.

 Copernicus * mm/degrees, tolerance + / - 15%. Support plate parts: torsion spring support plate has four parts: 0 ° and 90 °, 180 ° and 270 ° ( You can look at the picture) 。 Spiral bearing: right the spring, second hand azimuth sinistral spring clockwise rotation. Everyone can all the two spiral spring to manufacturing. Spring package number: every spring is the only number: type. ( De*10) 。 ( d*100) 。 ( N*100) 。 In view of the spring right-handed, marked as D. For left-handed spring, marked as G. N tag number of turns. Such as: D. 028. 020. 0350 # express right-lateral torsion spring, diameter of 2. 8 mm, stainless steel wire diameter 0. 8 mm, the existing 3. Five laps.
