Abstract

By strain gauge measurements of spiral bevel gears, the influence of lengthwise crowning and relative displacements between pinion and gear on tooth root stresses was investigated. It was found that the crowning effects the load distribution over the lines of contact and the load sharing between pairs of teeth meshing simultaneously. For both influences a quantitative description could be derived. In the case of relative displacements, deviations in pinion mounting distance and in offset have the strongest influence on the root stresses. A method was introduced to determine the increase or decrease of maximum stresses that have to be expected for a combination of certain values of these parameters. Further, a optimization criterion was derived that allows finding the amount of lengthwise crowning producting the lowest root stresses for a certain service condition.
