Classification and Selection of Rubber Buffer Shock Absorbers

2018.08.14
Rubber buffer shock absorbers are classified according to their function:

1. Narrow sense rubber buffer shock absorbers that support various devices;

2. Rubber bumpers for the purpose of absorbing impact;

3. Rubber springs used as mechanical actuating members;

4. Dynamic dampers that eliminate vibration of a specific vibration frequency;

5. Rubber couplings are also included in the category of rubber buffer shock absorbers.

Rubber buffer shock absorber

Rubber buffer shock absorber can be classified by shape as follows:

1. Compressed type. This type is a rubber shock absorber that is mainly used for the compression direction. The advantage is that the load bearing capacity is large, but the elastic modulus of the compression direction cannot be chosen too low.

2. Shear type. This type is a rubber shock absorber that is mainly used for the cutting direction. Its load-bearing capacity is small, but the advantage is that the elastic coefficient can be chosen very small

3. Compound. It is a rubber shock absorber for the combination of compression and shear, with intermediate features of compression and shear.

4. Cylindrical type. This type of rubber shock absorber can be used for vibration damping in the vertical direction, axial direction, twisting, and distortion of the shaft. For the vertical direction of the shaft, similar to the compression type rubber alkali shaker, the load-bearing capacity is generally large, but the elastic modulus cannot be chosen too small.

Rubber buffer shock absorber selection

When we choose the shock absorber, we should first understand its characteristics, and then choose according to the environment. The rubber shock absorber is characterized by its shape can be designed as needed, the stiffness is adjustable, the damping ratio is larger than the spring, the shear, the tensile, the compression, and the installation are simpler.

At the same time, due to the nature of the product itself, there are many occasions where rubber products are very inappropriate. First of all, the rubber will become brittle at minus 30 degrees, losing its own elastic deformation. At that moment, there is no damping effect at all, so in an environment that is too cold, do not use rubber-based vibration-damping products to avoid the expected effect. If you are in a very hot environment, do not use rubber buffer shock absorbers. Otherwise, not only does it not have the expected damping effect, but even an accident may occur.
