Characteristics and Application Fields of Multi-groove Belt

　　multi-groove beltIt has the advantages of both V-belt and flat belt. It not only has the soft mechanical and strong characteristics of flat belt, but also has the advantages of compact and effective V-belt. Let's learn about the characteristics and application fields of multi-groove belt!

The main characteristics of 1. multi-groove belt are as follows.

1. When the multi-groove belt has large transmission power and the same space, the transmission power is 30% higher than that of the ordinary V-belt.

2. In the case of compact transmission system and the same transmission power, the space occupied by the transmission device is 25% smaller than that of the ordinary V-belt.

3. The multi-groove belt body is thin and soft, suitable for transmission with small pulley diameter and high-speed transmission. The belt speed can reach 40 m/s; small vibration, less heat and stable operation.

4. Multi-groove belt heat-resistant machinery, oil-resistant machinery, wear resistance, small elongation and long life.

2. multi groove belt application areas:

Multi groove belt is widely used in textile machinery, printing and dyeing machinery, airport logistics machinery, tobacco machinery, sports machinery, woodworking machinery, food machinery, automobile manufacturing machinery, ceramic machinery, steel machinery, stone processing machinery, paper printing machinery, electronic machinery, glass deep processing machinery, hardware processing machinery, wire and cable and other industries.

Multi-groove belt, also known as multi-wedge traction belt, is a kind of flat belt. The characteristics of multi-groove traction belt are that the contact area and friction between the belt and the pulley are large, and the load is evenly distributed along the belt width, so the transmission capacity is greater; Because the belt body is thin, light, soft, reasonable in structure and small in working stress, it can be worked with a small pulley; the inner surface is equipped with an annular rubber belt with 40 trapezoidal wedge at equal interval, its working face is the side of the wedge. The multi-groove belt also has the characteristics of small transmission vibration, fast heat dissipation, stable operation, small elongation, large transmission ratio, and high linear speed. In addition, it can also be driven on the back of the multi-groove belt and use an automatic tension adjuster. Longer life; obvious energy-saving effect, high transmission efficiency, compact transmission, small space occupation, and reliable transmission.

Multi-groove belt traction belt is especially suitable for high-speed transmission with compact structure and large transmission power. The models are: PJ PM type, length, width and thickness can be customized, hardness can reach 40-75 degrees, and temperature can reach -10-80 degrees. It is generally used in various tractors and extruders, and has high-performance traction effect on cables, PVC hose special-shaped plastic products and other products.

According to customer requirements, multi-groove belts can be made into PJ ribbed belts with different groove spacing, angle and inner circumference. Due to the large number of wedge-shaped working surfaces and large carrying capacity, the shortcomings of other V-belts with different lengths can be prevented. Moreover, the V-ribbed belt has the advantages of smooth transmission, high linear speed and compact structure. Multi-groove belt is mainly used for high-speed external grinding machine and other machinery, woodworking electric planer and other power tools transmission.

Cut three samples with a length of 250 mm from one PJ V-ribbed belt, and mark a marking line with a spacing of 100mm at the middle position of the PJ V-ribbed belt. When more than three samples cannot be taken from one PJ V-ribbed belt, samples can be cut from the same batch of PJ V-ribbed belt, but must be indicated in the report. 7.4.2 High temperature resistance test method
Place the sample at 100 ℃ ± 2 ℃ for 96 h ± 1 h and then take it out. After standing at laboratory temperature for more than 2h, bend it along a cylinder with a diameter of 20 mm at a contact angle of at least 90 °.
