Impact of design constraints on the spur gear pair parameters

During the gearbox design process, pinion and wheel parameters are selected so the transmission meets the client needs. The process is rather simple and often automated. However, when the special demands like the limited dimensions or weight are present, task becomes more complex, requiring systematic approach. In this paper we observe the impact of limited outer dimensions on the spur gear pair parameters. To find the optimal solution, we used the genetic algorithm optimization method and ISO standard for load capacity calculation. The gear module, the pinion number of teeth and the both profile shift coefficients were used as variables. The influence of constrained dimensions was examined on two different sets of input data ; each consisting of outer gearbox dimensions, rotational speed and desired gear material, representing pairs for different uses.
