Poly V Ribbed Belt

According to the section size of the ribbed flat belt, it can be divided into five types: PH type, PJ type, PK type, PL type and PM type.

It is a special v-belt with many wedges in the longitudinal of a piece of tape, belonging to the friction belt.

Poly V Ribbed Belt  Structure:

Top cloth :

is used for the protection of the belt back, it can make the whole belt body maintain a high integrity, prevent the generation of cracks along the direction of the belt length, when the need to contact with the guide wheel, its protection is particularly obvious;

The core of the rope for tensile material:

widely used at present is polyester cord, high-performance wedge belt has more application of aramid cord;

 its main effect is to bear more wedge must be some tension in the process of use, this makes the tensile body remain the state of stretching, avoid getting into the rubber wedge it under negative stress and damage;

The adhesive layer of multiple ribbed belt plays the role of "connecting from the top to the bottom;

Poly v belt drives with the friction between the rubber wedge is with pulleys to transmit power, which requires the wedge glue should have wear-resisting, heat resistance, anti-bending of also should have a higher fatigue, low compression deformation, the larger lateral stiffness and enough hardness etc.

Not only to ensure the glue on the lateral wedge has enough rigidity, and on the longitudinal has high flexibility.

Ribbed belt on car with the thin body and large contact area with the belt wheel, the stress area of the belt is increased and the negative pressure is reduced.

Because of the good flexion performance of multiple wedges, the belt wheel with small diameter can be used, which is of great benefit to improving the structure of automobile transmission device, making it miniaturized and energy-saving.
