Abstract: Two approximate solutions are given for Flügge’s closed cylindrical shell characteristic equation, valid for the lower and higher harmonics, respectively. It is shown that as the harmonic number ...

Abstract: A method is described for calculating the tooth contact stresses in internal gear pumps, and it is shown that a considerable reduction can be achieved in the maximum contact stress by altering ...

Abstract: A study is made of the motion of crossed helical gears. Exact expressions are derived for the position of the contact point on each gear and for the sliding velocity, both as functions of ...

Abstract: A numerical procedure is described by which gear pairs can be checked for possible tooth interference. Two commonly used rules for avoiding interference are assessed, and one of them is shown ...
