effects of irregularities in gears profiles
effects of irregularities in gears profiles
(OP)
Hi All
No design criteria here just general information
Does anyone have any white papers or information on the effect of irregularity's on the gear tooth profile, such as vibration, wear and any concerns.
Thanks in Advance

RE: effects of irregularities in gears profiles
The paper you linked only covers spur gears. But TE is also a concern with other gear forms such as helical, spiral bevel, etc. Besides noise/vibration, another significant concern when the gears operate at high PLV is dynamic tooth loads. Spur gear meshes tend to have lower contact ratios than similar helical gear meshes, which reduces the problem of dynamic tooth load at high PLV. For this reason, spur gears are rarely used at a PLV above 10K ft/min. AGMA 2001-D04 section 8 discusses "internally generated gear tooth loads which are induced by non-conjugate meshing action of the gear teeth."
