Function and characteristics of railway equipment rubber backing plate
Jun 06, 2023| The railway equipment manufacturer introduced that the track rubber backing plate is cushioned under the rails. The rubber backing plate eases the pressure on the rails when the train is running, improves the safety factor, and also increases the service life of the rails and accessories.
The track rubber pad is usually black, and there is a layer of steel plate inside the rubber pad, which increases the toughness of the rubber pad and ensures the quality of the rubber pad.
The rubber backing plate is made of oil-resistant rubber, which is mainly used for rail fixing of reinforced concrete crane beams, and can also be used as a backing plate for steel crane beam tracks.
It has the functions of reducing the wear of the track top; reducing the impact of the crane on the crane beam; reducing the wear of the crane rim; reducing noise;
Since the 7a-2 composite rubber backing plate is installed between the track and the crane beam, it not only increases the friction force between them, makes the rail difficult to move, but also avoids or reduces the gap between the track and the crane beam along the same length of the track. average phenomenon. Thereby improving the stress situation of the pressure plate bolts.
The cross-section of the elastic composite rubber backing plate is slightly convex in the middle, so that the force is reasonable. The small rectangular convex strips on the backing plate are easy to deform, which not only makes the backing plate and the track easy to contact, but also increases the elasticity of the backing plate and plays a shock-absorbing role.
A certain number of grooves are made on the contact surface between the track rubber backing plate and the track to reduce the internal stress under the wheel pressure and increase the friction between them; the four protruding feet on the rubber backing plate just clamp the bottom surface of the rail, so that the rubber The pad is always directly under the track without shifting. The "rubber pad" and the "upper tongue" of the pressure plate are an important part of the flexible track system.
