Door Hinge Friction Calculation

The normal force is equal to the weight of the object so this can also be written.

Door hinge friction calculation.

Most hinges can open a full 180 degrees unless the door is protected by a door stopper or another obstruction. With our component modules customers can easily specify their required torque value within the available torque range without extra cost. Some versions are available with asymetric behaviour up to almost one directional torque hinge e g. 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.

Didn t read calculate the force of friction using the formula. A constant torque hinge friction hinge position hinge is used to hold e g. Most friction hinges have the same torque in either direction. 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. Weight of panel 2 lblength of panel 10 in. For heavy machine covers. 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.

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.
