Door Hinge Friction Calculation

Multiply the angle by the torque to calculate the friction in newtons n.

Door hinge friction calculation.

Where n is the normal force and μ is the friction coefficient for your materials and whether they re stationary or moving. Most hinges can open a full 180 degrees unless the door is protected by a door stopper or another obstruction. If you want the hinge to hold in such a way that the panel starts to fall at a certain angle enter that angle for your calculation. Some versions are available with asymetric behaviour up to almost one directional torque hinge e g.

For displays or mirrors reell precision makes. The normal force is equal to the weight of the object so this can also be written. Torque weight x distance to center of gravity x cosine angle if weight is evenly distributed distance to cg is length 2 calculation assumes zero degree angle unless otherwise specified. A monitor or display or any sort of flip machine covers in the desired position.

As a designer and manufacturer of torque hinges leeco offers standard lines of torque hinge products that can be applied to most position control applications. A constant torque hinge friction hinge position hinge is used to hold e g. With our component modules customers can easily specify their required torque value within the available torque range without extra cost. For heavy machine covers.

Most friction hinges have the same torque in either direction.
