GEARS HUB: OVERVIEW

Gear is a toothed machined part, like a wheel or cylinder that meshes with another toothed part to transmit or generate motion or to change speed or direction. Function for a gear is to mesh with another gear basically, but gear can mesh with any device having compatible teeth, such as linear moving racks also. Sometimes gear engineers don’t use gears and relay on the advent of electronic controls and the availability of toothed belts because gears for height power machinery are difficult to design.

There are many categories in the Gears based on function and industry that can be combined in a multitude ways, some of which are meshing circular spur gears. Herringbone and helical gears utilize coved teeth for capable to high speed power transmission. Gears mate or mesh via teeth with very specific geometry, a gear's most important feature is that unequal sizes (diameters) can be combined to produce a mechanical advantage, so that rotational speed and torque of the other gear are different from that of the first.

Lets talk about the applications of the gears, we can say there is no machine without gears, it’s a important part for any machine have immense usage in all industries like automotive industries, defence, marine, agriculture, coal plants industry, steel industry, mining many more industries, in all our industrial gears holding a wide area of applications.

In advance machines, gears are used for two basic purposes like increasing or decreasing of rotation speed of torque or power. Torque is measure of force to produce torsion and rotation about an axis. For increasing and reducing torque a large drive gear is coupled to a smaller driven gear.

Geometry of Gears


The essential features of a gear mesh are:

Center distance: The distance between the centers of two pitch circles.

Pitch diameters: The tangent to two basic circles is the line of contact in gear vernacular. Where this line crosses the line of center establishes the pitch. The ratio of pitch diameters gives the velocity ratio.

Pitch: It is a measure of tooth spacing along the pitch circle.

Number of teeth: Pressure angle of the contacting involutes: The angel between the line of force between meshing teeth and the tangent to the pitch circle at the point of mesh.
