What should be considered when choosing the material of the synchronous belt

As an important component of the mechanical transmission system, the performance and service life of the synchronous belt largely depend on the choice of material. The working environment is one of the key factors that determine the selection of synchronous belt materials, among which factors such as temperature, humidity, dust and chemicals will affect the performance and service life of the synchronous belt. In high temperature or high humidity environments, materials that are resistant to high temperature and humidity, such as polyurethane (PU) or metal synchronous belts, should be selected. In dusty environments, metal synchronous belts have more advantages due to their external wear resistance and strength. In addition, for occasions where chemical substances may be exposed, materials with good chemical resistance should be selected to ensure the stability and reliability of the synchronous belt.

In addition to the working environment, load and speed are also important considerations for the selection of synchronous belt materials. In environments with high speed and large load changes, the synchronous belt needs to withstand greater tension and friction. Therefore, materials with higher strength and wear resistance, such as polyurethane or metal synchronous belts, should be selected. These materials have higher tensile stiffness and fatigue life, and can meet the use requirements under high speed and heavy load conditions.

Another key factor affecting the selection of synchronous belt materials is the input driving force. When the input driving force is large, the synchronous belt needs to withstand greater tension and impact. In this case, metal timing belts are preferred due to their high strength and good impact resistance. At the same time, metal timing belts also have excellent thermal conductivity, which helps to dissipate heat and improve transmission efficiency.

While considering the above factors, attention should also be paid to the plasticity of the timing belt. Some timing belts, such as polyurethane timing belts, can form conveyor-type timing belts with different functions by welding blocks of different shapes on the back. This plasticity enables the timing belt to meet a wider range of application needs, thereby improving its applicability in mechanical transmission systems.

In addition to material selection, design and manufacturing processes also have an important impact on the performance and service life of the timing belt. High-quality timing belts should have high-precision tooth shapes to ensure transmission accuracy and stability. In addition, reasonable design and manufacturing processes can also improve the wear resistance and anti-aging ability of the timing belt, thereby extending its service life.
