Second, the teeth were assumed to be evenly distributed along the pitch diameter, Figure 10.

The system incorporates the use of fixed-length, interchangeable wedge pins that locate and lock on the gear's pitch diameter, work with pieces with any number of teeth, and can compensate for varying teeth spacing and pitch values.
Recall from our past discussions there are three diameters on a thread: the major, the minor, and the pitch diameter. Look up the thread size in your Machinist Handbook.
Six of the rollers required a gear with only a 1-inch pitch diameter; a slightly larger seventh roller increased its pitch diameter by only 0.4 inch.
It accommodates gears with up to a 275mm pitch diameter. The machine's compact design includes a self-contained electrical enclosure and hydraulic unit for easy installation, with the overall footprint coming in at 2.3 x 3.4m.
Use the following formula to calculate the radial force on the shaft: F = HP x 126,000 x K/PD x RPM Where: F = Radial force on shaft, lb HP = Horsepower transmitted PD = Pitch diameter of sprocket or sheave, in.
Portable or Bench External and Internal Thread Inspection Systems incorporate functional and pitch diameter size measurements for UN, Metric, NPT, and all other thread forms.
Studying the evolution of the theoretical deviation to the cylinder worm processing with whirl processing, made with this program, a series of conclusions must be made: -the deviations are having higher values at the nose of tooth and lower at the pitch diameter
Refer to the Machinery Handbook or even look at the thread gages; you can see that the pitch diameter of the nut is larger than the pitch diameter of the bolt.
