Gear tooth thickness measurement
WebMay 15, 2024 · In order to determine the tooth size of a gear after taking into account the backlash allowance, you first must determine what the nominal tooth thickness should be. There are three methods for determining this value. They are chordal tooth thickness measurement, span measurement, and over pin or ball measurement. WebThe value measured is the sum of normal tooth thickness on the base circle, sbn, and normal pitch, Pbn (k –1). (See Figure 1). Figure 1 details the span measurement of a spur gear. As such, the span measurement is on the outside of the teeth. For internal gears, the tooth profile is opposite to that of the external spur gear. As such, the ...
