Joint Rubber belts are widely used in agricultural machinery. The standardized rubber v belt has a trapezoidal cross-section and no joints throughout the entire circle. It can be divided into 7 types: O type, A type, B type, C type, D type, E type, and F type.The cross-sectional area of the belt gradually increases from O type to F type. The selection of belt model is determined based on the transmitted power and belt speed, which involves many knowledge.

The outer protective fabric used in the joint triangular belt has always been mainly cotton canvas, and it still maintains this state to this day. For some of the those who require better bending performance, they also start to use cotton blended canvas, or even Total synthesis fiber canvas. Outsourcing protective fabrics will continue to maintain this trend in the future.

When installing the belt, the symmetrical center planes of the main and secondary pulleys of the unified circuit should be within the same plane, and the positional deviation should not exceed ± 3% of the center distance.

The joint v belt has two types of special belt core structure and rope core structure, which are respectively composed of four parts: wrapping fabric, top glue, tensile body, and bottom glue.

The banded v belt has two types of special belt core structure and rope core structure, which are respectively composed of four parts: covering cloth, top glue, tensile body, and bottom glue. The V-belt with rope core structure is easy to manufacture, and its tensile strength is just as common, but its price is not too high.
