They are similar in that both designs give longer service life compare to a belt driven camshaft and they do not need replacement within the expected life of the engine. They are different in that a chain driven camshaft is turned by a chain running off the crankshaft and a gear driven set up transmits the turning force from the crankshaft all the way up to the camshaft using gears alone.
A chain drive set up may have some sort of tensioning device for the chain that may occasionally wear out
What are the similarities and differences of drive theories and
both of them are random access memories
With a chain drive the driven wheel will always rotate in the same direction as the drive wheel, but in a gear drive the direction of rotation will change between drive wheel and driven wheel.
Belt drive is quieter, but can be damaged by stones caught between belt and sprocket.
Belt drive is smoother and lasts much longer. Chain is better for very high torque and big swing arm movement applications, but replacement through chain stretch and sprocket wear a regular unwelcome expense
It is chain drive.
A chain and sprockets.
there is no it is a waste of money
slack of the chain
Chain
If your car is in first gear then you are in drive. Dont mix up the differences between manual and automatics transmissions
It's called the drive chain.
