Introduce the structure, principle and advantages of rotary damper in one minute
The specific structure of the rotary damper is based on a standard gear, and the shape of the gear is a gradual type. This form of gear works well, and can even be said to be excellent in operation.
When it comes to rotary dampers, many people will wonder, is this an industrialized name? In fact, just hearing the name "rotary damper" seems to be an industrial institution far away from us. Seems to be related to making large aircraft engines or buildings. Anyway, it doesn't matter much. In fact, the rotary damper is a small thing. And it is an indispensable little thing in your daily life. Homeowners can find it on some small machinery in their own home, and sometimes they can even install it themselves. So, what is the rotary damper then?
1. The specific structure of the rotary damper
The specific structure of the rotary damper is based on a standard gear, and the shape of the gear is a gradual type. This form of gear works well, and can even be said to be operational.
2. Principle of rotary damper
Rotary damper is a general term for parts. It uses hydraulic principle and electronic work. In order to improve the vibration isolation effect of rotary damper, the structure of rotary damper usually adopts passive device. The rotary damper has an electromagnetic bearing, the structure of the rotary damper is good, and it has electromagnetic and anti-vibration properties at the same time.
3. Advantages of Rotary Dampers
The importance of sportiness and fit is not used in the gear, and the parts around the rotary damper are arranged to work together to achieve the ultimate goal. In addition, the rotary damper has evolved from a shock-resistant damper, so the life of the rotary damper will also be extended, thereby extending the life of the item that uses the rotary damper.
4. Development process and application of damper
1. Warehouse shelves
In a gravity rack warehouse, the goods are affected by gravity and accelerate on the inclined warehouse runway. If the goods move freely, the impact of the goods on the shelves will cause damage to the goods, operator risks and damage to the overall structure of the shelves. Dampers play a very important role in this.
2. Engineering structure
In the 20th century, especially in the past 2 to 30 years, great efforts have been made to improve the anti-vibration capability of buildings, and remarkable results have been achieved. The pride of this achievement is the "structural protection system". People get rid of the traditional concept of beams, columns and walls to improve the ability to resist vibration, combined with the dynamic performance of the structure, cleverly avoid or reduce the damage of earthquake and wind. Base isolation (BaseIsolation), various energy absorption and energy dissipation systems using dampers, mass resonance damping system (TMD) and active control (ActiveControl) shock absorption system on the roof of high-rise buildings have all moved towards engineering practice. . Some have become indispensable protection measures to reduce vibration. Especially for unpredictable earthquakes, in multi-dimensional vibrations where the failure mechanism is not yet clear, the protection system of such structures is more important.
