The difference between Li, La, LW and le of triangle belt of corn harvester

There are many corn harvesters in the market, including various brands, two lines, three lines, four lines, etc. At the same time, the matching V belt models of different harvesters are also very many, disorderly, which makes the Agricultural machinery operator suffer a lot, and the manufacturers are also very difficult. For the Agricultural machinery operator friends, it is difficult to put them on the four English suffixes. What is the connection between Li, LD, La and le, the user does not know. Today, Today I'd like to introduce you

Li is the inner circumference of the V-belt, which is the inner circumference of the V-belt we measured by expanding.

La refers to the length of the outer circumference, including the joint belts  and the single belts are the same.

The more fuzzy is that the identification of LD and le, LD, refers to the reference length, and Le refers to the effective length

How does LD and Le differentiate?

Today, take the pulley and belt to introduce the meaning of the two V belt marks, LD and le. The reference length and effective length we usually call the pulley are that we measure the pulley, and have a reference line, The length corresponding to the reference line is called the reference length. When the reference length is on a single belt, the position of the line rope is about. The effective length should be reflected in the length measuring machine or installed on the pulley. It refers to the length of the outer circle of the belt wheel in the transmission system. In the joint belt, we can find that the effective length Le is obviously different from the outer circumference LW, Because there is a height difference between them, which is what we call the exposure height.

In addition, remind you that there may be nothing behind some models. This is a brand-based view. The representative meaning of V belts of different brands is different.

You should not look down on these English suffixes. The size of the V belts  will be different due to your neglect. Finally, the V  belt for goods preparation cannot be used, which will affect your harvest.
