| Abstract | ||||
| The flash temperature is one of the important factors for evaluating the scoring resistance of the gear teeth. In the present paper a numerical solution of the flash temperature for W/N circular arc gear due to moving heat source is done taking into account the partitioning of the heat in the contact zone to each tooth and all the variables for the design of this type of gears. Tooth load speed of rotation, module, radii of curvature, helix angle, gear ratio, number of teeth and contact ratio are considered. The theoretical results of the flash temperature arte presented and discussed with the above variables. A curve filling of the results is done and the following formula derived for the flash temperature ᶿ/µ = CP0.9725, N0.369, m0.968, p < sup>0.994, CR0.706, β0.193 This formula represents a simple tool for the designer to calculate the flash temperature the corresponding load carrying capacity and life of the gear are determined. The study also shows that there is a certain minimum value for the flash temperature with the change of the gear ratio. | ||||
