60.T Clutch Gear and Chain Sproket

Modern metallurgy has greatly increased the useful life of automotive gears. Automotive gears transmit torque and rotation through an angle from a power source to the driven member. Extreme pressure gear oil is a lubricant for automotive gears and bearings.
Automotive gears are machined from wrought bar stock and subsequently heat treated to develop the required surface hardness and tooth bending fatigue durability.
Automotive gear ratio is the number of turns of the drive wheels in relation to the number of turns of the engine. If the engine is considered the input and the drive wheel is considered to be the output then the input gear or the pinion is said to mate with the output gear or the ring gear to drive or rotate it.
