Conjugate Relief in Gears/ Transmission Error

  1. Nov 17, 2011 #1

    1) Transmission Error: I understand it is the deviation of the driven gear from its theoretical position based on the driving gear moving with uniform angular velocity. Ie it is a measure of the where the driven gear actually is compared to where it should be.....but I dont understand how this would induce noise or vibrations...the tooth pair are always in contact so there wouldnt be any vibration

    I dont find it physically intuitive....

    2)Could anyone explain to me (or provide sources of information) to what is conjugate relief in gears in the context of micro geometry analysis? Ie, I am looking at a graph of conjugate relief as a function of roll angle...
