The designation 1.8 T refers to the specific parameters of the timing belt, particularly its tooth profile and pitch. Timing belts are usually characterized by their pitch, which is the distance between the centers of adjacent teeth. The 1.8 in the name indicates a microtolerance tooth profile that allows for greater precision in engagement with the pulleys. The “T” indicates a type of tooth shape, typically trapezoidal, which enhances grip and reliability.

There are several types of V-belts designed to meet various operational needs. These include classical V-belts, narrow V-belts, and cogged V-belts. Classical V-belts are widely used in numerous applications, while narrow V-belts provide a more compact design for applications with space constraints. Cogged V-belts feature notches along the belt's length that improve flexibility, allowing for better gripping on smaller pulleys and enhancing performance in high-speed applications.

The core of a variable belt drive consists of a pair of pulleys connected by a belt. These pulleys can change in diameter or spacing, which alters the effective gear ratio between the input and output. By adjusting the distance between the pulleys or changing the width of the belts, operators can control how power is transmitted and at what speed. Hydraulic, mechanical, or electronic methods often facilitate these adjustments, making the system versatile in responding to different operational demands.
