Estimation of Sliding Loss in a Parallel-Axis Gear Pair
The meshing model and the method used for estimation of sliding loss in a parallel-axis gear pair are presented. First the sliding loss model for single tooth meshing spur gear is constructed. The sliding loss is attributed to the deviation in direction of force from the line of action due to fricti...

| description | The meshing model and the method used for estimation of sliding loss in a parallel-axis gear pair are presented. First the sliding loss model for single tooth meshing spur gear is constructed. The sliding loss is attributed to the deviation in direction of force from the line of action due to friction. Afterwards the sliding loss of a helical gear pair is considered. The helical gear is modeled as the multi-section spur gears aligned slantwise along with base helix angle. Thus the sliding loss of each section can be considered as same as the loss of the spur gear pair. Then the total sliding loss is estimated by combining the losses of all sections together. To verify the method, the estimated results were compared with the experimental results and estimated results done by the other researchers. The estimated results agree with the experimental results. The sliding loss increases with loads and speeds. The gear with larger module has higher sliding loss. Increasing the helix angle, the sliding loss will be increased, but increasing the transverse pressure angle the sliding loss will be decreased. Various empirical formulae of friction coefficient are used in this paper, and the accuracies of various formulae are shown. |
