This relationship may also be stated in an equation, and may be simplified by using letters to indicate the various values, as follows  [Pg.286]

Di = first pitch diameter D2 = second pitch diameter Di + D2 [Pg.287]

In many cases, particulariy on machine repair work, it may be desirable for the mechanic to determine the diametrical pitch of a gear. This may be done very easily without the use of precision measuring tools, templates, or gauges. Measurements need not be exact because diametrical pitch numbers [Pg.289]

Many machine trains utilize gear drive assemblies to connect the driver to the primary machine. Gears and gearboxes typically have several vibration spectra associated with normal operation. Characterization of a gearbox s... [Pg.302]
