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

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

Straight Sided Splines

Involute Splines

Splined shafts and hubs are usually used as connectors in many different types of applications. One of the most common applications is to connect motors to gear reducers. They may also be used in transmissions.Involute splines resemble spur gears, but tend to have different pressure angles.

Method of ignition

SI engines, mixture is uniform (conventional engines), mixture is non-uniform (stratified-charge engines) ignition is by the application of external energy (to spark plug)

CI engines, ignition by compression in conventional engine (Diesel engine), pilot injection of fuel in gas engines (eg, natural gas and diesel fuel – dual fuel engines)

AIR STANDARD CYCLES

AIR STANDARD CYCLES
Because the products of combustion are not too different from air (in terms of thermodynamic properties) we can analyse the engine cycle as a series of reversible non-flow processes using air as the working fluid throughout the cycle.This is known as an air-standard cycle.
