Gear is a mechanical part with teeth that can mesh with each other. It is widely used in mechanical transmission and the whole mechanical field. Modern gear technology has reached: gear modulus 0.004 ~ 100 mm; Gear diameter from 1 mm to 150 meters; Transmission power up to 100,000 kilowatts; Speed up to hundreds of thousands of RPM; The highest circumferential speed is 300 m/s.

Tooth width b -- Axial dimension of tooth.
Face pressure Angle ɑ T -- Acute Angle between the radial line of the intersection of the tooth profile and the indexing circle and the tangent line of the tooth profile passing this point.
Standard Rack: a Rack that has the dimensions of the base circle, tooth profile, full tooth height, crown height, and tooth thickness to meet Standard spur gear specifications. A Rack that has been cut to Standard gear specifications is called a Standard Rack.
Standard Pitch Circle: the Standard Pitch Circle used to determine the dimensions of gears. Is the number of teeth x modulus
Standard Pitch Line: the tooth thickness measured at or along a specific Pitch Line on a rack, 1/2 Pitch.
Action Pitch Circle: when a pair of spur gears bite, each one is tangent to the rolling Circle.
Standard Pitch: if the selected Standard Pitch is used as the base Pitch, it is equal to the base rack Pitch.
Pitch Circle: the track left on the contact point of each gear at the center line of two gears is called Pitch Circle.
Pitch Diameter: Pitch circle Diameter.
Effective Working Depth: a pair of spur gear crown height and. Also known as working tooth height.
Addendum: Difference in radius between the Addendum circle and the node circle.
Backlash: The gap between the tooth surface and the tooth surface when two teeth are occluded.
Clearance: The Clearance between the top of one gear and the bottom of the other when two teeth fit.
Pitch Point: the Point at which a pair of gears bite and are tangent to the Pitch circle.
Pitch: the distance between two adjacent teeth of corresponding point arc.
Normal Pitch: Pitch measured by the same vertical line along a specific section of involute gear.
Transmission ratio : the ratio of the rotational speed of two meshing gears. The rotational speed of the gear is inversely proportional to the number of teeth. Generally, N1 and N2 represent the rotational speed of two meshing teeth
