What is Pk Belt

V-ribbed belt refers to the ring rubber belt with flat belt as the base, while the inner surface of the arrangement with equal spacing of 40 ° trapezoidal wedge, its working face is the side of the wedge. We use PK belt to transmit the power among the crankshaft pulley, AC compressor pulley(fan), tension pulley, water pulley, alternator, hydraulic pump…These parts are separated to each other, it is this piece of belt to make them work together.

Compared to V belt, V-ribbed belt has many advantages. V-ribbed belt has more transmission power, almost 30% higher than the ordinary V-belt when at the same space. V-ribbed belt makes the transmission system compact, and the space that the transfer device takes is 25% lower than ordinary V-belt under the same transmission power. With thin body and rich flexibility, it is able to adapt to the small-diameter pulley drive and could also drive multiple wheels at the same time. Besides, it adapts to high-speed transmission, the speed could be as fast as 40m/s; what's more, the belt has such advantages as small vibration, less heat and smooth operation. And its resistance to heat, oil and abrasion ensures its small elongation in use and long life.

Tips to V-ribbed belt

1. Wedges of V-ribbed belt broke down in use

• Band wheel does match the V-ribbed belt;

• Wedges of the belt are exposed to some solvents or other chemical medicine;

• Working temperature is too high, the cooling method should be improved;

2. Parameters of the wheel does not match the standard or the wheel gets rusty.

Precautions for purchase of V-ribbed belt

Choose a V-ribbed belt with right models and suitable wedges that are compatible with the wheel diameter and wedge slot.

Precautions for the use of V-ribbed belt

1. When the belt is exposed to oil or water in use, it is suggested to clean or dry it up immediately;

2. The wrap angle is too small, it is suggested to change the position of the wheel on the reverse
side so as to increase the angle;

3. The tension of the belt is too small, it is suggested to enhance the tension;


4. V-ribbed belt makes noise in use

• The belt skids in use, it is suggested to dry it up in time;

• The wedge of the belt is inserted with something, it is suggested to add a protective cover for the transmission of the belt;

• The belt wheel position deviated, it is suggested to modulate it;

5. Large vibration of the belt in use, it is possible that the tension of the belt is too small, it is suggested to enhance it.

Our quality guarantee

Our PK belt is delivered to our customer after going through strict quality tests from the feeding process to a finished product. Following are the quality tests concerning PK belt.

1. Quality control of rubber compound composition: conducting a test over the rubber compound composition of each single batch of primitive compound to ensure that the compound conforms to the standard.

2. Quality control of hardness and weight: conducting spot checking over finished belts to ensure the stability as well as qualification of the hardness and weight of each belt.

3. Quality control of the belt length in each barrel: conducting spot checking over the belt length in each barrel to control the tolerance under 0.05mm

4. Test of the tension of the string: conducting a test over the tension of the string of each batch to ensure that its tension conforms to the standard.

5. Test of the service life: conducting a spot checking over the service life for about a season or even 6 months, therefore, what are left are all high-quality belt after screening, which means that the quality of our PK belt is ensured.
