Torsion
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.
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.
torsional spring can store and release energy or by torsion Angle of body static fixed axis rotation arm to a particular device.
This kind of spring is usually a dense body, but, spring coil between nodal distance in order to reduce friction.
They spin or rotate to generate resistance force.
News leaf spring hardware, as the name suggests, find extensive use in leaf spring hardware institutions. Since leaf spring hardware has become much dependent on technology in today's world, there is wide use of such News.
