Torque hinges, also known as friction hinges, and traditional hinges are both types of mechanical devices that allow rotational movement around a fixed point. However, there are several key differences between the two types of hinges.
Function: The main function of traditional hinges is to provide a pivot point for a door or lid, allowing it to open and close. Torque hinges, on the other hand, provide resistance to rotational movement, allowing a door or lid to be held at a specific angle or position.
Design: Traditional hinges typically have two or more plates or leaves that are joined by a pin or rod. They are designed to be visible and often require additional hardware such as screws or bolts for installation. Torque hinges, on the other hand, are often designed to be hidden and may require specialized mounting or attachment methods. They also typically have a single plate or leaf that is designed to provide resistance to rotational movement.
Load capacity: Traditional hinges are typically designed to support heavier loads than torque hinges. They are often used in applications such as doors, gates, and cabinets where strength and durability are important. Torque hinges are typically used in lighter-duty applications such as laptop screens, tablet stands, and automotive seats.
Range of motion: Traditional hinges typically provide a full range of motion, allowing a door or lid to swing 180 degrees or more. Torque hinges, on the other hand, are designed to hold a position within a specific range of motion. They may provide a limited range of motion, such as 90 degrees, or a more precise range of motion, such as 15 degrees.
Friction resistance: Traditional hinges typically have a fixed amount of friction resistance based on the tightness of the pin or rod that joins the plates or leaves. Torque hinges, on the other hand, can be designed to provide variable levels of friction resistance, allowing for precise control over the amount of force required to move the door or lid.
In summary, traditional hinges and torque hinges have different functions, designs, load capacities, ranges of motion, and friction resistance. While traditional hinges are typically used for heavier-duty applications that require strength and durability, torque hinges are often used for lighter-duty applications that require precise positioning and control.
