So after boils down to the tensile strength and shear strength of material, of course with the fourth strength theory to calculate the Von Mises stress for material can withstand great strength, combined with the length of the
spring, can calculate the big allow reverse Angle.
of course, we also can find that different applications, including
torsion spring turns is also different, so, it will involves a lot of physics and mathematics knowledge.
Through needed to hold the device size, resistance to calculate the torsional spring need laps.
And, in the process of calculation, according to the actual requirements of applications to design the rotation direction of the torsion spring.
the category of torsion spring for all spring design principle is a kind of complex, the change of the pattern is also quite lively, so the design theory also involved is complicated.
Torsion spring belongs to the spiral spring.
Torsion spring end was fixed to other components, while the rest of the component rotates around the center of spring, the spring pull them back to the initial position, produce torque or turning force.
Torsional spring (
扭力弹簧)
Is the extreme of the variations in the spring, from single torsional spring to double torsional spring torsion spring abnormity, and the deformation of various torsion bar, in accordance with the design shape.
So when the design is also more difficult to master the necessary information of the torsional spring:
1, free length;
2, control the diameter, outer diameter, inner diameter, the inside diameter of casing, or through the outer diameter of round rod.
3, steel wire size wire diameter;
4, materials (
Types and grades)
；
5, laps: the total number of turns and right-handed or left-handed;
6, torque: deflection pounds to a certain Angle;
7, the large deflection (
Free position to calculate the Angle)
；
8, the end of the form;
please note: material diameter, outside diameter, arm length, height of freedom, and other geometric dimensions, such as torque and the corresponding guide and corresponding torsion Angle.
