How to calculate the bearing capacity of the hinge？

The calculation of the bearing capacity of the hinge is usually based on the principle of mechanics, which needs to consider the weight, shape, size of the object, as well as the type, size, structure and other factors of the hinge. Here are some specific calculations and considerations:

First, calculation method

1. Single hinge bearing calculation formula:

F = W × (L – e) / L

Where F represents the maximum force that the hinge can withstand (unit N), W represents the weight of the object (unit N), L represents the length of the object (unit m), and e represents the distance between the center of gravity of the object and the hinge (unit m).

2. Double hinge bearing calculation formula:

F = W × (L1 + L2 – 2e) / (2L1)

Among them, F represents the maximum force that the hinge can bear (unit N), W represents the weight of the object (unit N), L1 and L2 respectively represent the length of the object (unit m), e represents the distance between the center of gravity of the object and the hinge (unit m).

Second, consider factors

1. The weight, shape and size of the object: these factors will directly affect the load-bearing requirements of the hinge. The greater the weight, the stronger the bearing capacity required; Shape and size affect the position of the center of gravity and the torque distribution.

2. Hinge type and structure: Different types of hinges (such as flat, cylindrical, ball, etc.) and structure have different effects on load-bearing capacity. For example, cylindrical hinges usually have a greater load-bearing capacity than flat hinges.

3. The material and size of the hinge: the material and size are also important factors affecting the load-bearing capacity. In general, stainless steel and copper hinges have higher load-bearing capacity, while iron and zinc alloy hinges have lower load-bearing capacity. At the same time, the larger the size of the hinge, the greater the load-bearing capacity.

4. Use environment: Use environment will also have an impact on the bearing capacity of the hinge. For example, in humid or humid environments, the load-bearing capacity of the hinge may be reduced by factors such as corrosion.

Third, practical application

When calculating the bearing capacity of the hinge, it is necessary to consider the above factors comprehensively, and evaluate and select according to the specific situation. For example, when choosing hinges for doors and Windows, factors such as the weight, size, opening mode and use environment of doors and Windows need to be considered; When choosing cabinet hinges, you need to consider factors such as the weight of the cabinet door, opening Angle and frequency.

In addition, in order to ensure safe use, the following points need to be noted:

Select the appropriate hinge type and size in strict accordance with the load-bearing capacity requirements.

Avoid overloading the use of hinges to avoid safety accidents.

Check the fastness and operation status of the hinges regularly, and maintain and replace them in time.

In general, the calculation of the bearing capacity of the hinge is a process that takes multiple factors into consideration, and needs to be evaluated and selected according to the specific situation.
