small flat belts

The term 5PK refers to a specific type of V-belt that has five ribs or grooves. The “P” stands for “poly V,” which describes the belt's construction. These belts are typically made from durable rubber or polymer materials reinforced with fibers to enhance strength and longevity. The 5PK belts are widely used in automotive applications, such as in power steering systems, air conditioning compressors, and alternators, as well as many industrial applications.

The working mechanism of tooth belts is based on the interaction between the belt's teeth and the pulley grooves. When the pulley rotates, the teeth of the belt mesh with those of the pulley, creating a mechanical link that transmits torque. This system allows for high torque transfer with minimal backlash, which is particularly advantageous in applications requiring precise positioning, such as in robotics or CNC machines. Additionally, tooth belts operate quietly compared to chain drives, making them suitable for environments where noise reduction is essential.
