The structure of the neoprene timing belt is composed of the following four parts:
(1) Glass fiber tensile layer
Glass fiber tensile layer is a rope composed of multiple strands of glass fiber. It is spirally wound around the tape's pitch line along the width of the tape. It has high strength, low elongation, good corrosion resistance and good heat resistance.
(2) Neoprene tape back
The neoprene tape back firmly adheres the glass fiber to the knot line, and plays a role of protecting the tensile material. When a belt back is used in the transmission, it can prevent damage caused by friction. It is better than the polyurethane belt back It has superior hydrolysis resistance and heat resistance.
(3) Neoprene tape teeth
The belt teeth are composed of neoprene with high shear strength and appropriate hardness. They need precise molding and precise distribution positions to properly mesh with the tooth grooves of the pulleys. The tooth roots must maintain a specified distance from the pitch line. No change.
(4) Nylon Covering
The nylon cloth cover is the anti-friction part of the protective tape. It should have superior abrasion resistance and consist of a nylon cloth with a small friction coefficient.
Chloroprene timing belts have better hydrolysis resistance, heat resistance and impact resistance than polyurethane timing belts. Its transmission power range is large. Especially in high power transmission, polyurethane timing belts cannot be compared with them. Working temperature is generally -34 ～ 100 C
