A crown wheel is a wheel with cogs or teeth set at right angles to its plane and the pinion is a small cogwheel that meshes with the crown wheel. The pinion thread is specially....

Sprockets are used to run chains or belts. They are typically used in conveyor systems

Double Helical Gear is of cylindrical form. It has two sections of teeth, right hand and the other left hand. They operate by engaging themselves simultaneously with the teeth of....

Screw gears are helical gears of opposite helix angle will mesh when their axes are crossed.

A rack is basically a straight gear used to transmit power and motion in a linear movement.

Internal gears typically resemble inverted spur gears but are occasionally cut as helical gears.

Herringbone gears resemble two helical gears that have been placed side by side. They are often referred to as " double helicals" .
One benefit of herringbone gears is that it....

Helical gears are very similar to spur gears except the teeth are not perpendicular to the face. The teeth are at an angle to the face giving helical gears more tooth contact in....

Spur gears are by far the most common type of gear and with the exceptions of the " cog" the type of gear that has been around the longest.
Spur gears have teeth that run....

Worm gears are used to transmit power at 90Â ° and where high reductions are required. The worm resembles a thread that rides in concaved or helical teeth.

Bevel gears are used mostly in situations that require power to be transmitted at right angles ( or applications that are not parallel) . Bevel gears can have different angles of....
