Most Comet torque converter systems range in ratio from approximately initially through about when "fully shifted. Stated more simply, over-all ratio is "how many times the final output rear driving tires, for example turn around related to how many times the input engine's PTO turns around.
Conversely, the latter would travel more quickly though it could not handle as great a load or as difficult a terrain. Of course, other factors which affect the machine speed and load-handling ability are the engine HP and RPM and also the drving tire's diameter. Menu Search Account Compare.

There are no gears, no complicated controls or levers and neither manual shifting nor clutching is involved in these systems. The basic operating principles of the variable speed drive system of the type used in many RV's are shown in the above illustration. 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 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. Both the clutch and the driven units are composed of pulleys with moveable sheaves. The moveable sheaves allow for the pitch diameter, offering infinitely variable power ranges. How does it work? The drive clutch 1 is activated by centrifugal force from the engine crankshaft.
The moveable sheave of the clutch is forced in as shown above as the rpm of the engine is increased. This contacts the drive belt 2. 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 driven unit is 3 forced out, as shown, allowing the belt to seek its smaller, high speed ratio diameter. As this happens, the speed from the engine transferred to the final drive is increased. The illustrations show the variable speed drive system in the extreme low position broken lines - 2 and the extreme high position solid lines - 2.
The system is infinitely variable between low and high ends. Why use a Comet Torque Converter System? 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.
Each Comet system is fully automatic and can be used anywhere that control by engine throttle alone is desireable. Available in three gear ratios , , , our compact worm gearboxes are built in extremely compact footprints for applications where space is limited.
