There are no gears, no complicated controls or levers and neither manual shifting nor clutching is involved in these systems. Each Comet system is fully automatic and can be used anywhere that control by engine throttle alone is desireable. Since these devices consist of a 'belt' and two 'variable pitch pulleys' all working together harmoniously, serving as both clutch AND transmission, we often call them 'variable speed drive systems.' Weather-proof, completely mechanical and occupying minimum space, they can operate mounted in any position and are adaptable to a wide variety of applications, both stationary and vehicular.Why use a Comet Torque Converter System?.The system is infinitely variable between low and high ends. The illustrations show the variable speed drive system in the extreme low position (broken lines - 2) and the extreme high position (solid lines - 2). As this happens, the speed from the engine transferred to the final drive is increased. The moveable sheave of the driven unit is (3) forced out, as shown, allowing the belt to seek its smaller, high speed ratio diameter. The drive belt will then be forced to a larger diameter within the clutch sheaves, thus pulling it to a smaller diameter within the driven unit (3) sheaves.

The moveable sheave of the clutch is forced in (as shown above) as the rpm of the engine is increased.

The drive clutch (1) is activated by centrifugal force from the engine crankshaft.

The moveable sheaves allow for the pitch diameter, offering infinitely variable power ranges.

Both the clutch and the driven units are composed of pulleys with moveable sheaves. The engine clutch is activated by centrifugal force, and the driven unit is torque sensitive, meaning it is responsive to the torque demand of the driven shaft or jackshaft, to adjust the ratio of the system for the power required according to the various conditions. The variable speed drive system normally consists of an engine clutch (1), and a driven unit (3), connected into a system by a 'V' type belt (2). The basic operating principles of the variable speed drive system of the type used in many RV's are shown in the above illustration.What is a CVT (Continuous Variable Transmission) drive system?.
