How are the inner and outer diameters of the V-belt represented?

Triangle belts come in different specifications and models, and the inner and outer diameters of different specifications of triangular belt products are also different. Next, let's talk about how the inner and outer diameters of triangular belts are represented.

LI: Inner diameter, LD LW LP refers to the pitch circle, L A outer circumference.

L: Ordinary triangular belts generally follow the standards Z, A, B, C, D, etc.

LD, LP, and LW are generally narrow V-band execution standards for SP series and XP series.

LA generally refers to English standard 3V, 5V, etc.

Number of turns thickness=outer diameter - inner diameter (this is the relationship between inner diameter, outer diameter, thickness, and number of turns)

The area of the circle formed by the outer diameter - the area of the circle formed by the inner diameter=length * thickness (this is the relationship between the outer diameter, inner diameter, length, and thickness)
