Some knowledge points of damping wheel

Damping What should be paid attention to when using for wheels? Gear transmission is one of the most commonly used forms in machinery. Nowadays, the gear system is developing in the direction of high speed, heavy load, light weight, high density and automation. In gear transmission, the problem of noise caused by vibration is becoming more and more prominent, and the control of axial vibration of gear transmission is the key to reduce noise. Therefore, according to this situation, a damping material is added to the gear, or a damping wheel is made of the damping material.

Damping wheel is a physical quantity used to measure the system's ability to consume vibration. Damping materials may also be referred to as viscoelastic materials. Under a certain force, it has some characteristics of a viscous liquid and will consume energy, while an elastic solid material will store energy. Because of this feature, in the form of gear transmission machinery, damping wheels are used to eliminate the noise and resistance of mechanical movement, which has been fully utilized in important mechanical industries.

Damping wheel can be divided into one-way gear and two-way gear. It is widely used, such as car sunroof switch, car audio flip, car refrigerator flip, car ashtray, various electronic and electrical appliances flip, trash can flip, Computer host panel, etc., play a shock-proof buffer effect on the product. And the flip effect is more rhythmic, thereby improving the level of the entire mechanical movement effect.

These are the advantages of damping wheel . damping wheel is characterized by low noise transmission, shock absorption, self-lubrication, and high mold processing production efficiency. Of course, different industries, different types of damping wheel , specifications are not the same.

When using damping wheel , you should also pay attention to some matters. Simply put, it can be said from the following points that it is easy to make mistakes and affect the performance of the pressure damping wheel. Let us learn the main points of using the low pressure damping wheel .

1 . Due to the harsh environment of construction machinery. Therefore, the sealing performance of the pressure damping wheel is required to be high, and dust and other impurities should be prevented from entering the pressure damping wheel during use. To prevent sharp tools from scratching or damaging the surface of the gas spring piston rod, do not apply paint or corrosive chemicals to the piston rod.

2. The stroke of the damping wheel should be added with a certain margin (about 10mm) on the basis of the working stroke to avoid errors during installation. It affects the service life and performance of the pressure damping wheel.

3. Pressure damping wheel installed on construction machinery. Due to the use of the environment in the outdoor, the service life is generally short. Consider when designing.

4. damping wheel working environment temperature range is generally -35~60.

5. The damping wheel cannot withstand lateral force or oblique force during operation. Otherwise, eccentric wear will occur, resulting in early failure of the gas spring, which should be considered in the design.

6. Suitable for light weight, no locking device door structure. When closing the door, the connecting line between the fixed support point and the movable support point of the gas spring passes through the center of rotation to ensure that the elastic force of the gas spring can close the door, otherwise the gas spring will often push the door open. For heavy door structures (covers of machines), locking devices are usually provided.

7. When the gas spring is closed and in working condition, there should be no relative movement. The amount of continuous expansion should be controlled within the required range.

8. The door structure of construction machinery (such as the cover) is generally heavier. When choosing a gas spring, consider choosing a gas spring with a safety device to avoid safety hazards caused by the failure of the gas spring.

9. Gas springs shall not be used as restraining devices. In addition, it is also necessary to increase the limit device, generally using rubber head for limiting.
