Timing belts can be used as transmission or conveying. Different industries have different requirements for timing belts. Some customers will require green cloth on the surface of the timing belt. So what are the benefits of adding green cloth to the timing belt? Let Barbieri Let me explain to you why some timing belts have cloth on the tooth surface and some have cloth on the back, what are their functions and differences.
Timing belt with green cloth can be divided into:
1. Timing belt with PAZ7 ,Tooth surface green cloth
2. Timing belt with PAR7,Green cloth on the back
3. Timing belt with PAZ7-PAR7,Double-sided green cloth
Timing belt plus cloth is mainly: to reduce noise; increase friction and anti-skid function.
(Our company can choose from customers: green cloth/white cloth/black cloth)
1. Timing belt with PAZ7 : It is mostly used in high-speed systems, because the timing belt and the pulley will inevitably make noise when driving, and the purpose of adding green cloth to the tooth surface of the timing belt is to reduce noise. Its existence makes there is a buffer zone between the teeth of the timing belt and the teeth of the pulley, so that they are no longer mechanically moving during meshing transmission, reducing the friction coefficient and achieving the effect of reducing noise .
2. Timing belt with PAR7: The method of adding green cloth to the back of the timing belt is not a measure to reduce noise, because in some special conveying occasions, it is necessary to increase the friction on the back, so that Green cloth is added to the back of the timing belt, which can effectively increase the friction force to meet the production needs, effectively prevent slipping, prevent pollution and protect product transportation, etc.
