Analyze how to slow down the vibration of reducer parts

Nowadays, the society pays more and more attention to environmental protection issues, and the requirements for some noises are also very high. When the parts of the reducer vibrate, some noises may be generated, so how to alleviate them?

Selection of spring isolator styles for reducer accessories:

Generally, a self-supporting spring shock absorber is selected, which has the advantages of simple structure and low cost; the spring is exposed to facilitate the observation of the spring state at any time. The spring that needs to be replaced shall be disposed of in advance to avoid the sudden settling of the vacuum pump when the spring is rusted and damaged. Damage and pipe breakage, etc.

Choice of spring:

Generally, shock absorber manufacturers need to meet the following requirements when selecting springs: the diameter of the spring should not be less than 0.8 times its height under the rated load; the spring must have a certain extra stroke, and the vortex flowmeter should be at least equal to 50% of the rated static deflection; The horizontal rigidity is at least 100% of the rigidity to ensure the stability of the shock absorber.

弹簧减振器挠度的选择:通常减振器厂商所提拱的弹簧减振器额定挠度一般为25MM(自频率值约3-4HZ),此挠度可应于650转每分钟的真空泵的隔振。当转速低于650时,建议使用40以下挠度之弹簧隔振器。

Add inert base:

In order to meet more stringent vibration standards, it is undoubtedly the best choice to use a spring isolator when installing an inert base.

Install rubber vibration isolator:

The choice of rubber isolators: the materials are generally neoprene (CR), natural rubber (NR); compression-type rubber shock absorbers are generally used, and for lighter weight vacuum pumps, shear-type rubber shock absorbers can be selected; relative Compared with spring shock absorbers, the vibration isolation performance of rubber shock absorbers is relatively different.
