Numerical Investigation of the Effective Parameters on Reducing the Machining Time of the Straight Tooth Bevel Gear

When there is a need to transfer power between non-parallel shafts, bevel gears are used. Bevel gears are widely used in power transmission systems such as car differentials and helicopter gearboxes, so knowing and improving the performance of this type of gear is particularly important. It is important and necessary to accurately calculate the machining time of the desired bevel gear in order to reduce time and costs. In this paper, data are collected using Taguchi's test design method in three levels. The amount of machining time was calculated for each test, then with the help of signal-to-noise analysis, the influence of the input parameters on the design of the straight tooth bevel gear on the reduction of the machining time has been investigated. The investigated parameters are conversion ratio, allowable contact stress and allowable bending stress.According to the obtained results, the conversion ratio parameter was found to be the most effective parameter on reducing the machining time. The optimal value of the conversion ratio was reported at level 1 with a value of 1.5.
