What is the impact of material selection on the performance of rubber transmission belts

As one of the core components of modern mechanical transmission systems, the performance of rubber transmission belts is greatly affected by material selection. Different material combinations have an important impact on the wear resistance, temperature resistance, strength and flexibility of the transmission belt.

Rubber material

The rubber material of a rubber drive belt is one of the key factors that determine its performance. Common rubber materials include natural rubber, synthetic rubber (such as nitrile rubber, neoprene, fluorine rubber, etc.) and silicone rubber. Different rubber materials have different wear resistance, oil resistance, high temperature resistance and anti-aging properties, and are suitable for different working environments and application scenarios. For example, natural rubber has good wear resistance and flexibility and is suitable for general industrial transmission; while nitrile rubber has good oil resistance and wear resistance and is suitable for transmission in lubricating grease environments.

Reinforcement layer material

The reinforcement layer is the support layer of the rubber transmission belt and is mainly used to withstand tensile force and torque. Commonly used reinforcing layer materials include polyester, nylon, steel wire, etc. Different reinforcement layer materials have different strengths, fatigue resistance and high temperature resistance, which directly affect the load-bearing capacity and service life of the transmission belt. For example, the polyester reinforced layer has high strength and fatigue resistance and is suitable for general industrial transmission; while the steel wire reinforced layer has higher load-bearing capacity and high temperature resistance and is suitable for high-load, high-speed transmission occasions.

Fillers and additives

Fillers and additives are auxiliary materials in rubber transmission belts, used to improve the rubber's processing performance, wear resistance, oil resistance, etc. Commonly used fillers and additives include carbon black, vulcanizing agents, anti-aging agents, etc. Different fillers and additives can improve the properties of rubber. For example, carbon black can improve the wear resistance and oil resistance of rubber, and vulcanizing agents can promote the vulcanization reaction of rubber and enhance the strength and fatigue resistance of rubber.

Surface coating

The surface coating is an additional coating on the surface of the rubber transmission belt to improve the friction properties, anti-skid properties and wear resistance of the rubber. Common surface coatings include rubber surface coating, cloth surface coating, oil surface coating, etc. Different surface coatings can provide different friction coefficients and wear resistance properties, suitable for different working environments and application scenarios. For example, rubber surface coating can improve the friction between the transmission belt and the transmission wheel, enhancing transmission efficiency and transmission stability; while cloth surface coating can improve the wear resistance and stretch resistance of the transmission belt and extend its service life.
