positive drive belt

A poly V belt, often referred to as a multi-rib belt, is designed with several longitudinal ribs on one side and is flat on the other. This design allows the belt to maintain a strong grip while minimizing slip, subsequently improving transmission efficiency. Poly V belts are commonly used in automotive applications, HVAC systems, and various industrial machinery. Their ability to deliver power through compact spaces and operate quietly gives them a significant edge over traditional belts.

A CVT transmission belt, also known as a drive belt or variator belt, is a unique belt that plays a pivotal role in the operation of a continuously variable transmission. Unlike traditional automatic or manual transmissions that use fixed gear ratios, a CVT can adjust the ratio infinitely within a given range. This capability is primarily achieved through the movement and tension of the CVT belt, which connects two pulleys—the primary pulley and the secondary pulley.
