Introducing Railway Equipment Rubber Backing Plates

In railway equipment, the rubber backing plate is an inconspicuous existence, but the role of the rubber backing plate cannot be ignored. Next, let’s learn about the rubber backing plate together!

The rubber backing plate is made of rubber. Natural rubber is widely used because of its small change, large tensile force, long elongation when damaged, and low price. The rubber pad has long-lasting high elasticity, and has good shock absorption, impact isolation and sound insulation properties.

When selecting the rubber backing plate, it should be considered to avoid making the rubber work under tension for a long time as much as possible, and the deformation of the rubber should be controlled within the allowable percentage range according to the thickness.

The main performance parameters of rubber shock absorbers are stiffness and damping. According to the changing speed of the loading force, it is divided into three types: static stiffness, dynamic stiffness, and impact stiffness. The three stiffnesses of rubber shock absorbers are different.

It should be pointed out that the temperature has a great influence on the stiffness of the rubber shock absorber, the temperature decreases and the stiffness increases;

As the temperature increases, the stiffness decreases. The installation and use of rubber pads should be based on factors such as machine characteristics, vibration strength, disturbance frequency, and environmental requirements. Try to choose processes and equipment with less vibration, determine the placement of rubber shock pads, and use them reasonably. wait.

It is necessary to understand the vibration characteristics of machinery and equipment, as well as the possible consequences. Reasonable use of rubber shock-absorbing pads, and other shock-absorbing measures.
