摘要： A method for designing a gearset meeting one or more design targets is described. In particular, the design target is efficiency. Initially, a size and ratio of the gear set is specified. Gear friction coefficients are then calculated, and a value for a design target for the gear set is calculated. One or more of the macro-geometry parameters are modified, and the macro-geometry parameters are chosen such that the advantageous effects of one macro-geometry parameter on the design target counteract any disadvantageous effects of another macro-geometry parameter. In this way, a design for a gearset meeting the one or more design targets is produced. The efficiency calculation includes the effect of a lubricant. Further design targets can include gear noise and gear durability.

摘要： A method for designing a planetary gearset meeting one or more design targets, comprising the steps of specifying a size and ratio of the gearset, specifying a number of planets, calculating all valid combinations of tooth numbers and planet numbers that satisfy one or more constraints, selecting a starting combination, calculating a value for a design target for the gearset and modifying one or more macro-geometry parameters. The macro-geometry parameters are chosen so that the positive effects of one parameter on the design target counteract any negative effects of another macro-geometry parameter. This method produces a planetary gearset meeting one or more design targets. The design target may be for bending strength wherein the last step comprises calculating bending strengths for the gear teeth and comparing with the target design, modifying the macro-geometry parameters when outside of the design target. The macro-geometry parameters may relate to the module and comprise reducing power loss by reducing contact length between two meshing teeth and increasing bending strength by increasing either one of the pressure angle, helix angle, face width or centre distance. The method can be implemented on a computer system as part of a computer-aided engineering system.
