How To Determine The Tightness of The Rubber V-belt

In modern industry, there are mainly mechanical transmission, hydraulic transmission, pneumatic transmission, and electrical transmission. Among them, mechanical transmission is the basic transmission mode, which transmits motion force and motion through meshing transmission and friction transmission, and plays an important role in it. The degree of tightness is usually determined based on usage experience, and it is good to adjust it so that the belt does not slip during transmission. There is no theoretical calculation basis. There are several types of belts, and there are also many specifications for belt length. When the tightness of the belt can be transmitted normally, it is important to manually press the middle part of the belt. The longer the belt, the greater the degree of compression.

According to everyone's experience, the most popular way for rural diesel engines to drive the working machine is to apply a force of about 20N (about 2kg) in the tight span of the rubber belt, with a sinking of 8-12mm. The correct inspection method for the use of the joint v belt model is to apply a vertical pressure of about 2 kilograms by hand in the middle of each tape, with a sinking amount of (20-30) millimeters. If it is not suitable, it should be adjusted in a timely manner.

What tests should be done for rubber v belts?

1. Appearance quality;

2. Fatigue performance, no torque fatigue life not less than 1.0X107 times, and 24-hour center to center distance change rate not exceeding 2%;

3. The tensile strength of the V-belt, the elongation at reference force, the adhesion strength of the wire rope, and the adhesion strength between the fabric and the adhesive;

4. Dimensional reference length limit deviation, exposed height, variation in center distance, and compatibility difference;

According to everyone's experience, the most popular way for rural diesel engines to drive the working machine is to apply a force of about 20N (about 2kg) in the tight edge span of this product, and the rubber belt should sink 8-12mm.

The structure of the rubber belt

Rubber belts are widely used in various types of enterprises such as mining and oil production machinery, port transportation, steel manufacturing, ceramics, cigarettes, cement, papermaking, textiles, etc. And provide supporting equipment for various consumer goods, such as washing machines, sewing machines, packaging machines, etc.

structure

1. The outer layer is made of special woven fabric, which has high tensile resistance and abrasion resistance, giving the surface a strong resistance.

2. The buffer layer and colloid part are made of high resistance to flexibility, high wear resistance, and low compression deformation rubber, which can maintain the normal cross-sectional shape of the tape during use.

3. The adhesive tape reinforcement layer is made of low elongation and high tensile aramid/polyester cord, which can fully utilize the function of the adhesive tape.
