Friction Hinge Basics | Reell Precision Manufacturing

Reell Precision Manufacturing — Sat, 01 Jun 2024 05:00:00 GMT

What Is a Friction Hinge?

Friction hinges, sometimes called torque or position hinges, are specially designed using resistance to control the motion of pivoting objects. Friction hinges are used to hold doors, panels, lids and screens solidly in position at any given angle, as well as determining the force required to move them.

To better conceptualize what a friction hinge is, think about the pivoting motion of laptop screens — one of the most common friction hinge applications in everyday life.

How Do Friction Hinges Work?

Unlike ordinary hinges, friction hinges are designed to provide rotational resistance. In order to achieve this, a special friction mechanism is used inside the hinge which restrains the hinge’s pivoting motion, ensuring a specific amount of force is required to open or close the object.

To suit a variety of applications, friction hinges are available in many forms, including:

How Much Weight Can a Friction Hinge Hold?

Friction hinges can be made from a number of different materials, helping to determine their load-bearing capacity. However, it’s important to first focus on torque, not materials.

The torque, or rotational resistance of a friction hinge determines how it will function in an application, providing a smooth, controlled motion, while also holding components solidly in their desired position. The amount of torque needed from a friction hinge depends on several factors, such as:

The weight of the object being held
The distance between the axis of rotation and center of gravity
The angle of the object relative to parallel

Reell's largest hinges can hold up to 11.3 N-m each, or 22.6 N-m for per pair. There is no “standard” weight this translates to, as weight is only one of the factors determining the necessary torque for your application.

For example, consider two different scenarios when holding a lid at 20° above parallel using two friction hinges. In each case, consider the weight of the lid evenly distributed so the center of gravity is exactly in the center and the lid has 2 hinges:

Common Materials Used for Friction Hinges

Friction hinges are available in a variety of materials. The right material for your needs depends on the application requirements. Metal friction hinges may provide the strength needed, or nylon options may be needed for weight conscious applications. Every material has its own set of properties, offering unique benefits.

Zinc friction hinges provide a cost effective solution with a good balance of strength and design flexibility. For improved visual appearance or chemical resistance, zinc friction hinges can be painted or coated.

Stainless steel friction hinges are strong, durable, and resistant to corrosion and oxidation. Many people turn to stainless steel friction hinges for outdoor use, where there is the possibility of exposure to moisture, salt, UV light and other harsh elements.

Aluminum friction hinges are also resistant to corrosion and oxidation, much like stainless steel, but have a much higher strength-to-weight ratio. This makes aluminum friction hinges ideal for reducing weight without sacrificing durability.

Glass-filled nylon friction hinges offer lower cost and greater versatility than metal hinges. These hinges provide an aesthetically pleasing and economical option for applications where weight is important and the strength of metal may not be required. Nylon can be used in traditional hinges, specially designed monitor mounts, and more.

How Long Do Friction Hinges Typically Last?

Friction hinge cycle life determines how long until the product fails to hold position as intended. Failure can lead to falling lids and potential injury. Some friction hinges last longer than others so look for products with rigorous testing and qualification. Lower priced products may last a few hundred cycles while some solutions may perform acceptably for thousands of cycles in various environments. In comparison, Reell friction hinges are engineered with patented ReellTorq® clip technology, providing consistent long-life, zero-adjustment performance of up to 50,000 cycles.

Common Friction Hinge Applications

Engineers use friction hinges where ever they need a pivoting motion or secure positioning. This includes laptop screens, equipment lids, furniture, monitor adjustment, self serve kiosks, lighting and medical devices.

Friction hinges are common in the transportation industry, used in airplane and bus headrests, tray tables and compartments, automobile center consoles, in floor storage, or adjustable mirrors and screens.

Choose the Right Friction Hinge

When selecting a friction hinge, consider a multitude of factors — including all the requirements of your application, along with the conditions it will be subjected to. These considerations include:

Weight, load and size requirements
Hinge location and angle
Orientation and rotational axis
Life cycle requirements
Environmental conditions and chemical exposure
Aesthetics and design factors

How to Create a Hidden Pivot Point with Torque | Reell Precision Manufacturing

Reell Precision Manufacturing — Wed, 01 May 2024 05:00:00 GMT

In some markets, surface mounted hinges and hardware can conflict with the current design trend of free flowing lines and smooth, clean surfaces. In other applications, surface mounted hinges, while reliable and easy to mount, can create issues with cleanability.

TI300 torque inserts from Reell create a smooth feel and infinite positioning internal to the assembly. Design engineers can create a hidden, torque enabled pivot point for a cleaner, eye pleasing design in just three simple steps. With a simple design trick, even the most challenging design configurations can incorporate a hidden torque element.

Step One – Create Installation Port

Referencing the installation port dimensions found in the Sales Drawing at Reell.com for the correct TI300 size, drill a blind hole in one rotating half to accept the knurled shaft. Then drill a blind hole to accept the main body in the other rotating half.

Step Two – Install the Main Body Portion of the Torque Insert

Making sure the main body is aligned with the installation port, press the body into the blind hole by pressing on the main body. Avoid pressing on the shaft itself as shown in Figure 1.

Step Three – Install the Knurled Shaft Portion of the Torque Insert

While aligning the second rotating half with the torque insert shaft, press onto the knurled shaft to the correct depth. A shim may be required to maintain the correct press depth as shown in Figure 2.

Design Trick

If the overall design doesn’t allow for a blind hole on each side, or the assembly process dictates a press of the two halves at the same time from one side, allow for the torque insert’s main body to be recessed and add a simple cap or flush plug to cover the hole as shown in Figure 3. By securing the two rotating parts and aligning properly, the torque insert can be pressed into each part with a single motion. Be sure the press tool presses on the main body while allow clearance to press the torque insert below the surface.

How the Right Torque Profile Can Solve Your Customer’s Problem | Reell Precision Manufacturing

Reell Precision Manufacturing — Mon, 01 Apr 2024 05:00:00 GMT

The feel and ease of adjustment is a key factor in the perception of quality, safety, and utility in a product. If the motion feels smooth and secure, the design feels safe and high quality. The movement builds confidence in the design because it feels right.

All systems requiring adjustment and positioning have an axis about which components move. Adding torque to the motion of that axis makes it feel better. Adding the right torque profile makes it feel perfect.

To understand how to effectively utilize the correct torque profile we consider:

3 types of torque profiles.
4 common problems the right torque profile can solve to improve your design.

Torque Profile Options

Smooth premium feel motion and sure positioning in both directions

Symmetric torque elements provide equal torque in the forward and reverse direction. Specify symmetric torque products to ensure the same feel in either direction, and when forces are generally the same over the entire range of motion, such as vertically mounted doors.

Symmetric torque is also commonly used where the overall positioning forces are low, making directional differences in torque less perceptible to end the user.

Easier to open with the same smooth quality motion and solid positioning

Differential torque provides lower torque in one direction than the other. Movement in the primary direction provides the full rated torque, while movement the opposite direction provides 60% of the rated torque. This enables designers to account for application conditions impacting the user experience, such as biasing a door so the force to open the door is less than the closing force. In more complex mechanisms different torque levels can be used to sequence multiple motions in desired order.

Very easy to open, with solid downward positioning Ideal for high-force vertical mounting applications

As the name implies, One-way torque provides torque in one direction and near zero torque in the opposite direction. A One-way torque element is particularly useful in heavy lid applications, removing all hinge torque in the upward direction when lifting against gravity, but still providing full support in the downward direction to hold the lid in place.
