Force exerted by driving tooth on the driven tooth along the line of pitch point to the point of contact of two teeth is known as

Gears are wheel-like machine elements that have teeth uniformly spaced around the outer surface. They are used in pairs and are a very valuable design tool. Gears are mounted on rotatable shafts and the teeth are made to mesh (engage) with a gear on another shaft. Gears use the principle of mechanical advantage, which is the ratio of output force to input force in a system. For gears, the mechanical advantage is given by the gear ratio, which is the ratio of the final gear's speed to the initial gear's speed in a gear train.

Gears use the principle of mechanical advantage, which is the ratio of output force to input force in a system. For gears, the mechanical advantage is given by the gear ratio, which is the ratio of the final gear's speed to the initial gear's speed in a gear train.

Types of Gears:
Spur Gear: The spur gear has a helix angle of 0°.
Worm Gear: Worm gears are found in right angle gearboxes. They “turn a corner.”
Helical Gear: This is an angle toothed gear. ...
Bevel Gear: Bevel gears tend to have a lower ratio and run at a higher efficiency than worm gears.
