Door Hinge Friction Calculation

For heavy machine covers.

Door hinge friction calculation. 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. 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. For example if the door can only be opened 120 degrees and the torque is 3 360 nm the friction is 403 200 newtons 120 x 3360 403 200.

With our component modules customers can easily specify their required torque value within the available torque range without extra cost. Most friction hinges have the same torque in either direction. The normal force is equal to the weight of the object so this can also be written. For displays or mirrors reell precision makes.

Some versions are available with asymetric behaviour up to almost one directional torque hinge e g. A constant torque hinge friction hinge position hinge is used to hold e g. Where n is the normal force and μ is the friction coefficient for your materials and whether they re stationary or moving. 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.

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