What are the main factors that affect the wear resistance of rubber driving belts

The wear resistance of a rubber drive belt refers to its ability to maintain surface integrity and performance when rubbed or rubbed against other surfaces. This property is critical to the performance of rubber drive belts in a variety of industrial applications.

Rubber material selection and hardness

Effect of hardness

The wear resistance of rubber transmission belts is closely related to the hardness of the rubber material. Hardness is usually expressed using Shore A or Shore D hardness. Higher hardness generally means better wear resistance, as harder rubber surfaces are more difficult to wear. However, too high hardness may reduce the elasticity of the rubber and affect the buffering performance of the transmission belt. A balance needs to be struck between hardness and elasticity.

Types of rubber materials

Different types of rubber materials have different hardness and wear resistance. For example, natural rubber, nitrile rubber, and neoprene have excellent wear resistance in some applications. Depending on the specific application, the manufacturer will select the appropriate rubber material and may customize it to improve wear resistance.

The role of additives and fillers

Filler selection

Adding fillers to rubber is an effective way to improve wear resistance. Fillers with higher hardness such as silica gel and silica can increase the wear resistance of rubber. These fillers are dispersed in the rubber matrix to form a hard mass that resembles tiny particles that resist wear and extend the life of the drive belt.

Lubricant additives

Additives with lubricating properties help reduce friction and improve the belt's wear resistance. These additives form a film that reduces the coefficient of friction between the rubber and other surfaces, slowing down the wear process. Stearate, polytetrafluoroethylene (PTFE), etc. are common lubricating additives.

Surface design and texture

Surface texture design

The design and texture of the drive belt surface directly affects the friction between it and other components. Properly designed textures provide greater surface area, dissipate frictional heat and reduce wear. In addition, the carefully designed surface texture helps prevent slippage and improve transmission efficiency.

Texture Manufacturing Process

The molds and manufacturing processes used in drive belt manufacturing also have an impact on surface texture. The high-quality manufacturing process ensures uniform and stable surface texture, preventing uneven wear and improving wear resistance.
