In general, spec torsion spring (torsion spring) is usually used on a supported mandrel or shank. It is recommended that the spindle size should allow about 10% clearance in the listed deviation. If the deviation is large, the shank size should be reduced. In order to make the spring function in good condition, the space in the assembly (minimum axial space) must be sufficient. The minimum axial space cannot refer to the length of the coil

In general, spec torsion springs are used on a supported spindle or shank. It is recommended that the spindle size should allow about 10% clearance in the listed deviations. If the deviation is large, the shank size should be reduced. In order to make the spring function well, the clearance in the assembly (minimum axial space) must be sufficient. The minimum axial space cannot refer to the length of the coil

Spec torsion spring should be used in the direction of winding coil. Because of the residual stress, the maximum load is low in the direction of loosening. The torque values listed are the recommended maximum torques. These values can be increased by about 20% with only a little adjustment under static conditions
During the inspection, the load should be applied to 1 / 2 of the strut length (E). The use of other lengths will slightly change the current length of the wire and affect the test results

For example, when en = 0.187, P = m / en = 0.047/0.187 = 0.251b, what is the load of component t012-090-055 when en = 0.187, P = m / en = 0.047/0.187 = 0.251b? The torque value of intermediate deformation can be calculated by direct proportion. For example, component t030-180-250,90. The torque value of deformation is 0.312 in LB (35.3 N-mm).
The listed reference torque values should be achieved at the listed deviations. The torque values at the intermediate deviation can be calculated by direct proportion. For example, the torque value of component t030-180-250 with 90 ° deviation is 0.312 in IB
