õõtsvedrud

Oõtsvedrud, often translated as torsion springs, are a type of mechanical spring that stores rotational energy when a torque is applied. Unlike extension or compression springs that work along a linear axis, oõtsvedrud are designed to resist twisting. They typically consist of a coiled wire that exerts a torque in the opposite direction to the applied twist. The ends of the spring are usually anchored to other components, allowing the spring to apply or resist rotational force.

These springs are commonly found in everyday objects and industrial applications. Examples include clothespins, where the oõtsvedru provides the clamping force, and garage doors, where they are used to counterbalance the weight of the door, making it easier to lift and lower. In more complex machinery, oõtsvedrud can be used in levers, hinges, and mechanisms requiring controlled rotational movement or a return to a specific angular position.

The design of an oõtsvedru involves careful consideration of factors such as wire diameter, coil diameter, number of coils, and the material used. These parameters dictate the spring's torque capacity, the angle through which it can operate, and its overall lifespan. Materials commonly used include various steel alloys, chosen for their elasticity, strength, and resistance to fatigue. The performance of an oõtsvedru can be affected by factors like temperature and the rate at which the torque is applied.
