■Torsion spring
・The correct direction to use a torsion spring is to use it in the direction in which the spring is rolled up.
- Twisting the spring in the winding direction will reduce the coil diameter. Therefore, the guide rod that passes through the inner diameter side is generally set at approximately 90% of the maximum load.
・The spring constant of this standard is calculated based on the arm length 1/2, the free angle B (135°), and the number of turns, and the allowable displacement is determined based on the assumption that it will be used under static load.
