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.
