Henry Spring is the largest spring manufacturing company maintain its leading position in the domestic spring industry, the initial production of watches and clocks spring, famous for the quality and stability, both in the spring production technology and equipment are the highest domestic.。
The torsion springs (torsion spring) is one of the widely used spring. Henry spring production of various specifications torsion springs (torsion spring) is well-known superior quality and stable. Henry spring HENRY (standing standard) torsion springs (torsion spring) and custom torsion springs (torsion spring) solution。

HENRYR everse the springs (torsion spring) - stainless steel standing size
The the Henry spring stainless steel HENRY (Standing criteria) torsion springs (torsion spring) with four end position。
Typically, the HENRY reverse the spring used in a supporting mandrel or arbor. Recommended mandrel sizes are listed in deviation allows about 10% The gap. If the deviation is larger, the size of the shafts to reduce. Assembly space (minimum axial space) must be sufficient to make the spring in good condition. The minimum axial space does not refer to the length of the coil.
HENRY reverse the spring should be used along the winding direction of the coil. Residual stress, loosen the direction, the maximum load is low. The torque value listed is the recommended maximum torque. Under static conditions, these values ??only need a little debugging will be able to increase by about 20%。
On inspection, the load acting on the 1/2 strut length (E). Other lengths slightly change the wire current length and affect the outcome of the trial。
By the formulaP= M / En ，Listed in the reference torque value can be converted to approximate direct load formula, P is the load acting on the length En。For example: Part of T012-090-055 when En = 0.187 P=M/En= 0.047／0.187= 0.251b,
How much load is？ Deformation in the middle of the torque value can be calculated through direct proportion。Such as；Part T030-
180-250，90。The deformation of the torque value is 0.312in-lb (35.3 N-mm)。
The reference torque value listed in the list of deviations to achieve. Torque in the intermediate bias value can be calculated through direct proportion. For example; parts T030-180-250, 90 ° deviation of the torque value is 0.312in-Ib.

HENRYTorsion spring (torsion spring) - piano wire material standing size
Piano wire torsion spring series used to supplement our stainless steel torsion spring series. Piano wire to reverse the spring end position, as shown below. The whole twist spring series in a standard size mandrel. HENRY reverse the spring in a supporting mandrel or shank axis above. The size of the recommended mandrel listed deformation allows about 10% of the gap. If the deformation is large, the handle shaft size should be reduced. Assembly space (minimum axial space) must be sufficient to make the spring in good condition. The minimum axial space does not refer to the length of the coil。
