How To Make A Torsion Spring Youtube There are 4 key torsion spring design flaws that can affect the performance of a torsion spring. 1. incorrect direction of operation 2. inside diameter too. A torsion spring is normally supported by a rod (mandrel) that is coincident with the theoretical hingeline of the final product. typical tolerances. tolerance values for torsion springs depend on the body diameter to wire diameter ratio and are about 10% in torque and 5% in diameter. The stationary cone must be toward the center of the garage door while the winding cone must be toward the outside of the door. 21. you may need to loosen the set screws for the spring to slide onto the shaft. 22. slide the spring and bearing toward the center of the door. 23. loosen the set screws on the cable drum. 24. The first formula calculates a torsion spring's spring rate: k = \frac {m} {\theta} k = θm. in this equation, we find: \theta θ — angular deflection. we can express the spring rate either as torque per radian k \mathrm {rad} krad or torque per rotation k \mathrm {rot} krot.

Step 3: make small adjustments. using the appropriate winding bar, turn the spring in the direction needed to adjust the tension. make small quarter turn adjustments and test the door’s balance after each turn. continue until the door opens and closes smoothly. Then, determine the angular deflection (degrees of motion) through which the spring leg is required to rotate. divide the torque by this angle to obtain the spring constant (rate) you require. (rate = torque degrees) or, if the torque required to rotate the spring through a given angle is required, use the formula (torque = rate x degrees).
