Features: T5 T10 Trapezoidal Timing Belt,Rubber Timing Belt For Paper Machine,AT5 AT10 AT20 rubber timing belt,Rubber Trapezoidal Teeth Synchronous Belt,timing belts,synchronous belts Huatao Industrial Belt Co., Ltd. , https://www.huataobelt.com
Trapezoidal Timing Belt is a synchronous belt used to transmit power, consisting of trapezoidal teeth arranged in rows. It transmits power from one shaft to another through the force of gravity and friction and is widely used in various mechanical equipment. It has the advantages of smooth transmission, low noise, compact structure and high transmission power.
The belt teeth are constructed from a reinforced neoprene compound containing aramid, which ensures the belt teeth have high shear strength.
High tensile strength, fiberglass cord provides high strength, high flexibility and high tensile elongation.
Neoprene protects it from dirt, grease, and moisture.
Application areas:
Printing, packaging, papermaking, machine tools, textiles, engraving, petrochemicals and other environments that require high load and high speed drive devices.
Description:
Mainly material is rubber or polyurethane, and the frame usually uses fiberglass cords or steel wires. It is characterized by good meshing performance and transmission efficiency, and is suitable for high-speed and high-precision transmission. The cross-sectional shape of a trapezoidal tooth is similar to an isosceles trapezoid. The size of the tooth top and tooth root are equal, and there is a fixed spacing between two adjacent teeth.
Trapezoidal timing belt are divided into two types: single-sided toothed and double-sided toothed, referred to as single-sided belt and double-sided belt.
