Torsion
spring because is to rely on the torque and rotating force to produce the effect, so for spring stiffness to have very strong demand, spring stiffness refers to the unit, is in a fixed Angle, formed by the rotary torque, if spring stiffness is insufficient, torque and rotating force is insufficient.
Besides torsion spring to be aware of is big deformation, load and rotate to specification three pay attention to the site.
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.
which refers to the large deformation of spring can withstand deformation degree, the degree is higher, the better.
Another big load refers to the spring on the premise of keeping rotary force, and the duration of the can, of course duration is as long as possible.
After talking is turning to the specifications, rotate to specification refers to the torsional spring rotate to the left or right, rotate Angle size, and so on.
Is, of course, the greater the Angle of rotation, the better.
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.
The , essentially perfected by leaf spring hardware, is one of the first home appliance to be widely distributed.
