Spur Gear Terms and Concepts - Gears Educational Systems

from the Pitch circle to the root circle. Clearance (C) Refers to the radial distance between the top and bottom of gears in mesh. Some machinists and mechanics refer to clearance as "play" or the degree of looseness between mating parts. Whole Depth (WD) Refers to the distance from the top of the tooth to the bottom of the tooth.

Sep 22, 2014· Arborists typically use trunk diameter to determine a root protection zone during development. A common guideline recommends a tree protection zone with a radius of one foot for every one inch of trunk diameter – a 12 to 1 ratio. It's important to stress that this is just a guideline.

Dec 11, 2020· While determining working voltages, we need to evaluate both peak and root-mean-square (RMS) voltages. The peak value of the DC voltage will determine the clearance, and the RMS value of the AC voltage will determine the creepage distance. Based on the working voltage, we calculate the minimum PCB line spacing.

The module is the measure of gear tooth size which is normally used for metric system gears. It is similar to the Diametral Pitch (DP), which is commonly used for English system (inch measure) gears but they differ in the units used and in that they bear a reciprocal relationship. Module is the pitch circle diameter divided by the number of teeth.
