Convert Between Different Gear Pitch Types

The following are the basic formulas for convert from diametral pitch, ciurcular pitch and module pitches.

D = Diametral Pitch         C = Circular Pitch            M = Module You Have You Need Rule Formula Diametral Pitch Circular Pitch Divide Pi (3.1416) by the diametral pitch C = 3.1416 / D Module Divide 25.4 by the diametral pitch M = 25.4 / D Circular Pitch Diametral Pitch Divide Pi (3.1416) by the circular pitch D = 3.1416 / C Module Multiply the circular pitch by 8.08505 M = C x 8.08505 Module Diametral Pitch Module divided by 25.4 D =  25.40 / M Circular Pitch Module divided by 8.08505 C = M / 8.08505 Other Topics IC engine, Air Standard Cycles, Method of Ignition, Gear Types, External vs Internal Gears, External Gear Pump, mechanical Engineering, Gears, Gears Purpose, spur gears,Helical gears,herringbone gear,Worm gears,Mechanical Pdf,English books,Photoshop tutorials,Physics files,Thamizh,Manufacturing,Gears pdf,Computer science,Harry potter,Best 100 english books,Rack and pinion,Face Gears,Involute Splines,Straight sided Spline

Bevel / Miter Gears

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 application but tend to be 90°

Helical Gears

 The teeth on helical gears are cut at an angle to the face of the gear. When two teeth on a helical gear system engage, the contact starts at one end of the tooth and gradually spreads as the gears rotate, until the two teeth are in full engagement.

This gradual engagement makes helical gears operate much more smoothly and quietly than spur gears. For this reason, helical gears are used in almost all car transmissions.

Because of the angle of the teeth on helical gears, they create a thrust load on the gear when they mesh. Devices that use helical gears have bearings that can support this thrust load.

One interesting thing about helical gears is that if the angles of the gear teeth are correct, they can be mounted on perpendicular shafts, adjusting the rotation angle by 90 degrees.

Gears The Purpose

Gears are generally used for one of four different reasons:

-

To reverse the direction of rotation

-

To increase or decrease the speed of rotation

-

To increase or decrease the speed of rotation

-

To move rotational motion to a different axis

-

To keep the rotation of two axis synchronized

Gears

Gears are wheels with teeth. Gears mesh together and make things turn. Gears are used to transfer motion or power from used to transfer  motion or power from one moving part to another.
