OEM Stainless Steel Industrial Usage Double Spiral Metal Torsion
Spring
Torsion spring is a mechanical part that uses elasticity to work.
Usually made of spring steel. It is used to control the movement of
machine parts, mitigate the impact or vibration, store energy,
measure the size of force, etc. Torsion Spring, namely Torsion
Spring, is a complex design principle among all types of springs
and the type change is quite lively, so the theory involved in the
design is the most complicated.
When the spring twists, the material is in a tensile or shear state
as mentioned in the torsion calculation, so the torsion Angle limit
is ultimately caused by the failure of the material, which cannot
be restored to its original state when plastic deformation occurs.
Of course, the Von Mises stress calculated by the fourth strength
theory is the maximum strength that the material can withstand.
Combined with the length of the spring, the maximum allowable
torsion Angle can be calculated.
Production line diameter: production wire diameter range
0.08mm-10.0mm Technical standard: according to customer
requirements, the company to solve the customer's best as its own
responsibility, but also to produce high precision spring
specialty. RoHS compliant: Able to measure more than 76 chemicals
and materials, plating thickness types of surface treatment:
