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 friction hinges have the same torque in either direction. 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 heavy machine covers.

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. 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 constant torque hinge friction hinge position hinge is used to hold e g. Weight of panel 2 lblength of panel 10 in.

With our component modules customers can easily specify their required torque value within the available torque range without extra cost. 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. Some versions are available with asymetric behaviour up to almost one directional torque hinge e g. Multiply the angle by the torque to calculate the friction in newtons n.

Most hinges can open a full 180 degrees unless the door is protected by a door stopper or another obstruction.
