The round belt is also known as polyurethane round belt. It is usually made of PU, and its Chinese name is polyurethane for short. With thermoplastic high-quality polyurethane materials, the physical properties such as density, elasticity and rigidity can be obtained by simply modifying the formula. At present, it has been widely used to replace glass fiber insulation materials, wood, traditional rubber products, etc
PU round belt characteristics:
(1) Smooth transmission, buffering and shock absorption capability,
low noise;
(2) Accurate transmission, no sliding when working, with constant
transmission ratio;
(3) Convenient maintenance, no lubrication and low maintenance
cost;
(4) It is not easy to break at low temperature, and the temperature
resistance range is - 35 ℃ to 80 ℃; Used for temperature of 20 ℃ -
60 ℃;
(5) It can be used for long-distance transmission, and the center
distance can reach more than 10m.
(6) It has excellent flexibility resistance, abrasion resistance,
impact resistance, oil resistance, water resistance, chemical
corrosion resistance, plastic agent, easy connection, installation,
long service life and other characteristics;
(7) The speed ratio range is large, generally up to 10, and the
linear speed can reach 50 m/s, with a large power transmission
range, up to several watts to hundreds of kilowatts;
(8) Nylon core and steel core can be added; Hardness range: Shore A
hardness 80A to 95A; Elongation: 5-8%<8; 5-6%>8; Very high
tensile strength
