Door Hinge Friction Calculation

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.

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

Most hinges can open a full 180 degrees unless the door is protected by a door stopper or another obstruction. 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. Didn t read calculate the force of friction using the formula.

For displays or mirrors reell precision makes. 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. Weight of panel 2 lblength of panel 10 in.

For heavy machine covers.
