According to the application requirements, design of the torsional
spring handedness (
Clockwise or counterclockwise)
To determine the spring handedness.
Each circle or closely around or separate around, can the torque (competency
At right angles to the axis spring)
。
The end of spring can wound as hooked or torsion arms straight.
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.
torsional spring is usually very tight, belong to the spring of the compact, not easily bend, hardness is strong.
But between each spring ring also has the regulation of pitch, the pitch can be very effective to reduce the friction between the spring coil.
In addition, the torsion spring on the rotating force or rotating force will produce resistance.
