As a transmission device, the belt is widely used in various fields. It has the advantages of large load capacity, high transmission efficiency, simple structure, easy maintenance and so on, and is widely used in many occasions. However, the performance of the belt also needs our attention. This paper will discuss the performance of the belt from the aspects of tensile strength, deflection and life.

First of all, the tensile strength of the belt is one of the important indicators to measure its performance. The belt needs to withstand a certain tension during the transmission process, so the higher the tensile strength, the better the stability of the belt during the transmission process. The level of tensile strength is related to the material of the belt, in general, polyester, polyamide and other materials of the belt tensile strength is higher, can meet the larger load requirements.

Secondly, the deflection of the belt is also an important indicator to examine its performance. The belt may experience a certain degree of deformation during the transmission process, which is called deflection. A belt with a large deflection will cause energy loss during transmission, thereby reducing transmission efficiency. Therefore, we need to choose a belt with less deflection to improve transmission efficiency.

In addition, the life of the belt is also our focus. The life of the belt depends on a number of factors, such as the use environment, load conditions, maintenance and so on. In general, we need to choose a better quality belt, and in accordance with the instruction manual for correct installation and maintenance, in order to extend the service life of the belt.

In addition, the friction coefficient of the belt is also one of the factors to be considered. The friction coefficient between the belt and the drive wheel directly affects the transmission effect. The higher the friction coefficient, the higher the transmission efficiency, but too much friction will also lead to energy loss and excessive wear, so it is necessary to choose the appropriate friction coefficient under the premise of meeting the transmission needs.

Finally, the use of the belt environment and wear resistance are also factors we need to consider. Belts in different working environments may be subjected to different degrees of wear, so it is necessary to choose a belt with good wear resistance. In addition, different use of the environment of the belt requirements are also different, such as high temperature, acid and alkali environment need to choose high temperature, acid and alkali resistance and other special materials of the belt.

In summary, the performance of the belt has an important impact on its transmission effect and service life. Correct selection of belt materials, reduce deflection, pay attention to maintenance, etc., can improve the working efficiency and service life of the belt, so as to better meet the transmission needs of different fields.
