How to distinguish the quality of the V belt?

**V-belt, first of all, you have to study the national standards of the V-belt carefully and master the technical data requirements of the standard. Secondly, we should understand the rubber and understand what kind of rubber is suitable for V-belts. Only by understanding these two issues will you be able to run a business.

What you tell here is not necessarily good. It's true that it's based on standards!!

Visual, feel, and according to standard inspection.

GB T3688 GB T3686 HG3056 There are so many standards that you need to find yourself.

There are numbers and letters on the back of the V-belt, which represent the V-belt model and specifications.

There are two kinds of triangle belt core structure and rope core structure, which are composed of four parts: cloth wrapping, top glue, tensile body and bottom glue. The V-belt of the rope core structure is easy to manufacture, the tensile strength is general, the first is cheap, and the V-belt with the core structure is widely used, with good toughness and high strength, and is suitable for occasions with high speed.

Check the method

Apply about 2 kg of vertical pressure to the middle of each tape by hand, and the sinking amount is 20 to 30 mm.

New and old do not mix: when two or more than three triangle tapes need to be replaced, the specified type of triangle tape should be selected, and the tightness of each group of triangle tapes is required to be consistent, and the new and old triangles are not allowed to be mixed or reduced to use, otherwise, the new and old triangle belts are unevenly stressed, and even the old triangle belts do not work, which affects the power transmission and shortens the life of the triangle belts.

V-band (V-belt) is divided into three types: ordinary, narrow and wide V-band, of which there are seven types of ordinary V-belt models: Y, Z, A, B, C, D, E, and F.

Common sizes:

Model Upper Width, Thickness, Angle.

a "(13mm) "( 40。

b "(17mm) "(11mm) 40。

c "(22mm) "(14mm) 40。

d "(32mm) "(20mm) 40。

e "(40mm) "(25mm) 40。

Different types of V-belts, e.g. A, B, C, etc. If they have different models and different specifications, then they are not the same size. For example, type A:

The width is 13mm. The thickness is 8mm. And type B:

The width is 17mm. Thickness is shaped: width is 22mm.

The thickness is. You generally use this to determine the type of belt you are using, and you are right.

1. The model specifications of the V-belt:

The specifications of the V-belt are planned by the size of the back width (top width) and height (thickness), according to the size of different back width (top width) and height (thickness), the national standard stipulates the O, A, B, C, D, E and other models of the V-belt, and the section width, top width and height of each type of V-belt are different.

According to the shape of the V-belt, various groove types are made, and these different groove types determine the O-type pulley, A-type pulley, B-type pulley, C-type pulley, D-type leather sensitive pulley, E-type pulley and other models of pulley.

2. The models of V-belts are: O, A, B, C, D, E, 3V, 5V, 8V for ordinary reinforced type, AX, BX, CX, DX, EX, 3VX, 5VX, 8VX, narrow V with SPZ, SPA, SPB, SPC, and strong and narrow V with XPA, XPB, XPC.

Each model of the V-belt specifies the cross-sectional size of the V-belt:

The cross-sectional size of the A-type triangle belt is the top width of 13mm, the thickness of the B-type triangle is the top width of 17mm, the thickness of the C-type triangle is the top width of 22mm, the thickness of the D-type triangle is the top width of the thickness of 19mME, the cross-sectional size of the triangle is the top width of 38mm, and the corresponding size (width * height) of the thickness is O(10*6), A (.
