If this gives me a goofy answer like 22.1, I suspect it is a metric gear, and divide 25.4 by the pitch (or divide the pitch by 25.4 and hit the 1/x button on the calculator) and see if it comes reasonably close to one of the standard metric moduli of 0.5, 0.8, 1.0, 1.25, 1.5, 2.5, etc.

The centre distance that the calculator returns is for the two gears in tight mesh. Some allowance will have to be made for backlash. This amount will vary depending on the tooth size of the gears and the manufacturing tolerances.

Backlash Base Circle Center Distance Chordal Thickness Circular Pitch Circular Thickness ... Gear teeth size varies inversely with Diametral Pitch. Pitch Diameter (D) The Pitch Diameter refers to the diameter of the pitch ... from the Pitch circle to the root circle. Clearance (C) Refers to the radial distance between

The arc movement measurement thus obtained is converted to degrees by applying the following equation: Backlash (degrees) = Arc Movement (inches) x 57.296/Radius (inches) The following table gives the American Gear Manufacturer's Association specified Backlash range for Coarse pitch Spur, Helical and Herringbone type of gears.

Table 7-2 Commonly used diametral pitches . Instead of using the theoretical pitch circle as an index of tooth size, the base circle, which is a more fundamental circle, can be used.The result is called the base pitch p b, and it is related to the circular pitch p by the equation (7-8) 7.5 Condition for Correct Meshing. Figure 7-5 shows two meshing gears contacting at point K 1 and K 2.

Module m represents the size of involute gear tooth. The unit of module is mm. Module is converted to circular pitch p, by the factor p.

2. Basic Gear Terminology and Calculation / Let's learn the basics of Basic Gear Technology ! Gear size, pressure angle, number of teeth…we introduce the basic terminology, measurement, and relational expressions necessary to understand basic gear technology.

Spur gear backlash is the amount of tooth space between mating gears at the pitch circle diameter. Backlash may be measured or specified in the transverse, normal, or axial planes, and in the direction of the pit circles or on the line-of-action.

Whether the resulting operating backlash lies between the maximum and minimum recommended backlash is a measure of the appropriateness of the gear drive. BHN ( Gear / Pinion ) : If a steel gear is used, Brinell Hardness (H b ) of the gear material is required for strength calculations.
