Dampers are relatively common devices in daily life, and are often used in aviation, aviation, military, guns, automobiles and other industries, bringing great convenience to our lives. Do you know what a rotary damper is? What is the role of the rotary damper? The editor-in-chief will talk to you about the content in this regard. If you are interested, come and find out.

A rotary damper is a device that provides motion resistance and consumes kinetic energy.

The rotary damper enables the moving part of the meter to quickly stop the device in a stable deflected position. In seismic instruments, dampers are used to absorb the natural vibration energy of a vibrating system, usually proportional to the speed at which the vibrating system is moving.

The rotary damper plays an important role in compensating the small friction and air resistance of the pickup swing system and changing the frequency response. Dampers are widely used in aviation, aviation, military, machinery and other industries.

If the goods are free to move, if the goods hit the shelves, it will cause damage to the goods, risks to the operator, and damage to the overall structure of the shelves. Dampers play a very important role in this. The damper (also called the reducer) on the gravity rack is mainly used for the gravitational acceleration generated by the goods on the gravity rack.

This allows the goods to descend smoothly and slowly along the track, eliminating hidden dangers. Guaranteed goods and operators. Here damping can be divided into external and internal.

The rotary damper makes the product move slowly and mechanically, which improves the quality and life of the product, and provides a one-way buffer and a two-way buffer.

Rotary damper features:

1. Speed

The rotational damper may slow down depending on the rotational speed and the torque will change accordingly. In this way, the law of the speed and torque variation of the rotary damper is known. The faster the damper spins, the more torque there is. The rotary damper is slowed down and torque is reduced.

2. Temperature

The rotary damper changes with the temperature of the surrounding environment, and so does the torque. According to this, the law of the temperature change of the rotary damper and the surrounding environment can be obtained. The higher the ambient ambient temperature, the lower the torque and the lower the ambient ambient temperature. Reason: As the ambient temperature changes, the viscosity of the brake fluid inside the rotary damper changes. However, if the ambient temperature returns to normal, the torque will return to its original value.

Rotary damper structure:

The specific structure of the rotary damper takes a standard gear as the main body, and the shape of the gear is gradual.

Use a 20-degree pressure angle with a diameter of about 0.35, the material is mainly shell and polycarbonate, and the gear material is acetaldehyde. It can be seen that the auxiliary torque with the gear as the center and the shaft constitute the rotational damper.
