Rubber timing belt

The specific composition of the product is:

* Neoprene ringless jointless belt

* Raw materials: Neoprene (Germany)

* Skeleton Material: Polyester Cord (Japan, UK)

* More than 2500 models to choose from

* Die width 480mm, any width can be customized. Neoprene timing belt with dynamic bending, crack resistance, good performance, ozone performance, anti-aging, heat, oil, wear and other characteristics. Widely used in textile, automotive, chemical fiber, cigarette, paper, printing, chemical machinery and equipment.

(1) Glass fiber tensile layer

     Glass fiber tensile layer is a rope composed of multiple strands of glass fiber. It is spirally wound along the width of the tape at the position of the nodal line of the tape. It has high strength, small elongation, good corrosion resistance and good heat resistance.

(2) Neoprene tape back

   Neoprene tape back It adheres glass fiber tightly to the pitch, plays a role in protecting the tensile material, and needs to be used in the transmission in the case of a back, to prevent damage due to friction, it is more than a polyurethane timing belt The back has superior hydrolysis resistance and heat resistance.

(3) Neoprene belt teeth

   The teeth are made of neoprene with high shear strength and hardness, and need precise molding and precise distribution position to properly mesh with the spline of the pulley. The root of the teeth should keep a specified distance from the pitch line, and the pitch should be when bending. No change.

(4) nylon cloth layer

   Nylon cloth layer is the anti-friction part of the protective tape and should have superior wear resistance. It is composed of nylon cloth with small friction coefficient.

   The resistance to hydrolysis, heat and impact of the neoprene timing belt is better than that of a polyurethane timing belt. Its transmission power range is large. Especially in high-power transmission, the polyurethane timing belt cannot be compared with it. Operating temperature is generally -34 ~ 80 C

Polyurethane timing belt:

Polyurethane timing belt is generally made of nylon thread (or steel wire, copper wire) as a tensile body, casted of polyester, with oil resistance, impact resistance, aesthetics and other characteristics.

Polyurethane timing belt is hard-wearing but it is not as good as rubber timing belt.

Chemical properties

- Anti-aging, waterproof solution, UV protection UVA, ozone protection

- Working temperature: -30°C～+80°C can withstand a maximum of +110°C for a short time

- Highly oil- and oil-proof esters

- Resists most acid and alkali corrosion

Rubber timing belt is good in flexibility, water resistance is good, PU is not water resistant, reciprocating work is poor, high and low temperature performance is poor, and wear resistance is good. Under normal temperature and static conditions, PU polyurethane timing belt is good. Otherwise, rubber timing belt is good. Polyurethane TPU timing belt is a thermoplastic polyurethane material, it has high modulus, high strength, high elasticity, permanent deformation, good winding, excellent wear resistance, oil resistance, low temperature resistance, aging resistance, can reach Medical and health requirements. Polyurethane TPU timing belt wear resistance is 8 times that of rubber timing belt, more than rubber timing belt health, is more suitable for food, medical industries, clean production industries. TPU timing belt has gradually replaced the rubber timing belt. TPU timing belt is widely used in computer embroidery machines, beverage machinery, and stained glass manufacturing industries. The skeleton material used by the company is aramid rope, not embroidered steel wire rope.
